Patent Number	Date	Title	Name	City	Description
14,863	May. 13, 1856	Handsaw	Jackson Gorham	Bairdstown, GA	Combination square and saw and the first in the 7/150 catagory. This patent was utilized by Henry Disston in the No. 42 and 43 series of saws and early examples will bear the incorrect patent mark of MAY 12,1856 instead of MAY 13,1856. Hiram Smith specifically mentions this patent as a basis for his patent, 20313, which was assigned to Henry Disston. Disston catalog pictures as well as know examples are marked with the incorrect patent date of MAY 12,1856 as well as JACKSON GORMAN in an arch above the date. A featured article in Scientific American, 15 AUG 1857, describes the saw as well as indicates to contact H. Williams, assignee, in Atlanta GA for more information.
20,313	May. 18, 1858	Device Attached to Handsaws for Squaring and Marking	Hiram Smith	Camden, NJ	References improvements on the Jackson Gorham patent, 14863, of 12 MAY 1856. Shoulder strips are riveted directly to the blade instead of the handle to ensure squareness is maintained. A sharp projection occurs at the beginning of the rule for reference and an awl is provided in the handle for marking.
20,337	May. 25, 1858	Leveling Device Attached to Handsaws	Henry Disston	Philadelphia, PA	One of the patents that is the basis of Disston's No 43, No 42, and No 39 combination saws. Text specifically mentions that it may be combined with the Jackson Gorham's patent 14863 (also noted on the 43 series saws). Patent is for the levels in the handle positioned for plumb and level with respect to the back edge of the saw. Note the spelling of Morse verus Morss. Strangely, the original patent page is missing the signatures to help asertain if this spelling is correct or an error in typesetting. Thomas L. is reported to be the father of Joab Morss of the venture of Disston and Morss.
		Leveling Device Attached to Handsaws	Thomas L. Morse (Morss)	Philadelphia, PA
29,680	Aug. 21, 1860	Machine for grinding saw-blades	Henry Disston	Philadelphia, PA	This machine hollow-grinds handsaw blades.
47,806	May. 23, 1865	Improved saw-setting machine	Charles Disston	Philadelphia, PA
59,950	Nov. 27, 1866	Improved Machine for Sharpening Saws	John Borthwick	Philadelphia, PA	Utilizes an emery rim or ring instead of a solid emery wheel or file in conjunction with a flange and plate to hold the saw. Several reference to the ease of use and the ability of children to operate the device. Available according the 1876 Disston catalog.
64,953	May. 21, 1867	Improvement in saws	Charles Disston	Philadelphia, PA
67,734	Aug. 13, 1867	Improvement in Hardening and Straightening Steel Blades	Henry Disston	Philadelphia, PA	Simulataneous hardening and straightening blades of steel using gradual pressure between plates and dipping the blades into the hardening composition while the blades are in a heated state. Disston subsequently applied for a different patent, 86286, since while this method worked well for handsaw blades and thin strips of metal, it did not allow larger circular saw blades to be adequately coated with the hardening composition.
70,423	Nov. 05, 1867	Improved Device for Setting Saw Teeth	Henry Disston	Philadelphia, PA	Notched swage hinged to rods that enable the cutting edges when set by the swage to be the same distance from the center of the saw. Believed to have been used due to the patent awarded later to John Baker, PN/79184 which modified the device.
70,424	Nov. 05, 1867	Improved Device for Sharpening Saw Teeth	Henry Disston	Philadelphia, PA	File and gauge for sharpening reciprocating saw teeth. The initial finished tooth serves to establish the next tooth. This device would be utilized with larger cross cut saws and within reciprocating sawmills.
72,766	Dec. 31, 1867	Improvement in Bolts for Saw Frames, &c	F. Washbourne	New York, NY	Head and shank made separately and then brazed together as an improvement over a cast saw bolt. Frequently found on American, and some Canadian, split nut saws and also sometimes observed with the patent stamped on the bolt. WRT Canadian use, Rob Paul reports "Flint of Rochester opened his saw works in St Catharines Ontario in 1856 (the first saw works in Upper Canada), and sold to R H Smith in 1870. From my collection, R H Smith initially used a J Flint medallion and his own blade etch which included "R H Smith, Successor to J Flint", then an early "R H Smith" flush mounted split-screw medallion has no patent date, and later surface mounted R H Smith medallions have the 1887 Glover Pat date"
73,238	Jan. 14, 1868	Improvement in circular saws	Henry Disston	Philadelphia, PA	Circular saw patented gullet tooth. Each tooth has the back edge formed as an arc of a circle with the center eccentric with the center of rotation (image 2). Sharpening lines of teeth continue to ensure that same number of teeth remain as the saw diameter is reduced thru sharpening. Use of one of Disston's patented gummer is referenced. Prominently displayed in the 1876 Price List
79,184	Jun. 23, 1868	Improvement in Swage for Circular Saws	John Gulick Baker	Philadelphia, PA	An improvement over Henry Disston's patent, 70423, which was apparently put into use at the Disston works and this patent reflect the experience with the earlier patent in use. The swage is hung loosely to the bar and its movement is independent but limited by a pin in the bar. Disston's patent had the swage secured to the bar when used.
80,242	Jul. 21, 1868	Mincing Cleaver	Samuel J. Tongue	Philadelphia, PA	Munn & Co.- patent attorneys This invention consists in combining a mincing knife or cutter, and a cleaver, in such a manner that one and the same implement may be used either in the capacity of a cleaver or a mincing knife, as desired. In using the implement as a cleaver, the handle is grasped horizontally, in the usual way, the cutting edge rising and falling in the vertical plane; but in using the device as a mincing-knife or chopper, the handle is grasped vertically, and worked up and down in that position. Blade is stamped "Disston, Philada, Warranted, Patent July 21st, 1868."
86,724	Feb. 09, 1869	Improvement in Screw Driver Handles	Eli S. Bitner	Lock Haven, PA	A smooth metal cap fits loosely in a socket in the top of the screwdriver to eliminate friction to the palm when driving screws. Sold by Disston and Sons in the 1876 Price List.
101,942	Apr. 12, 1870	Improved Method of Manufacturing Circular Saws	Thomas Taylor	Philadelphia, PA	Blade segments are formed by rolling instead of grinding.
105,370	Jul. 12, 1870	Improvement in reciprocating sawmills	Edward Rhodes	Philadelphia, PA	The invention relates to gang-saws, and the sliding frames to which they are attached.
105,543	Jul. 19, 1870	Improvement in Machine for Sharpening Saws	John Atkinson Borthwick	Philadelphia, PA	Sharpener on swinging frame and constructed and jointed to enable the saw blade to be sharpened in place without removing the blade. Available in 1876 Disston Price List

D4,497	Nov. 29, 1870	Design for a Saw	Edward Rhodes	Philadelphia, PA
109,881	Dec. 06, 1870	Improved Process for concave/vex Circular blades	Thomas S. Disston	Philadelphia, PA
110,751	Jan. 03, 1871	Improvement in Handles for Cross-Cut Saws	Thomas S. Disston	Philadelphia, PA	Special handle plate allows handles to be place on end or top of the saw. Additionally, two set screws allow the handle to be angled to suit the user's preference. Thomas Disston later patented the two set screw idea for adaptation for handsaws under patent 143128. Unlike his later patent, this patent does not appear to be adopted by Disston Saw Works.
111,619	Feb. 07, 1871	Improvement in Saws	Henry Disston	Philadelphia, PA	The saw is a combination of a common handsaw (x-cut) and a rip saw. Breasted toe enables cutting skirting as well as helping to overcome kinking when making ripping cuts.
		Improvement in Saws	Thomas Hill	Philadelphia, PA
112,007	Feb. 21, 1871	Improvement in Buck-Saw Frames	John Gulick Baker	Philadelphia, PA	Recessed metal socket with diagonal braces. Sold by Henry Disston & Sons as the Climax Frame No.77

126,527	May. 07, 1872	Improvement in Try Squares	Henry Disston	Philadelphia, PA	Try square that is a compromise between all metal and all wood handled try squares. Blade and metal stock are securely attached and the wood handle is recessed to accept a dovetailed rib on the stock.
		Improvement in Try Squares	Joab Morss	Philadelphia, PA
129,731	Jul. 23, 1872	Improvement in Saw Frames	William Hawley	Hawley, PA	Concave slotted shoulder and oblique cross bar. Appears to be listed as Brace Frame No. 70 in the 1876 Disston Price List although the oblique is opposite in the catalog picture.
130,484	Aug. 13, 1872	Improvement in Saw Tooth Swages	John Connor	Philadelphia, PA	Hammer used to reform and set saw teeth. Available in three sizes: large circular saw; small circular saws; and bandsaws and small circular saws. Listed in Disston's 1876 Price List - Conqueror Saw Swage
134,320	Dec. 24, 1872	Improvement in saw setting devices	Charles T. Shoemaker	Philadelphia, PA
142,445	Sep. 02, 1873	Improvement in files	Henry Disston	Philadelphia, PA
142,900	Sep. 16, 1873	Improvement in Tips for Saw Files	Henry Disston	Philadelphia, PA	Detachable rubber tip for use with a saw file to make the file easy to manipulate and protect the thumbs and fingers.
143,128	Sep. 23, 1873	Improvement in Hand Saws	Thomas S. Disston	Philadelphia, PA	Set screws to secure/remove the handle as well as allow the handle's angle to be adjusted to suit the user's preference. This saw handle was offered in the 1876 Price List with a saw blade of comparable quality to the No 7. Thomas Disston references his 3 JAN 1871 patent,110751, for a cross cut saw handle that uses the same premise and applies the principle to handsaws in this patent.
147,110	Feb. 03, 1874	Improvement in machines for making buck-saw frames	Thomas S. Disston	Philadelphia, PA
150,626	May. 05, 1874	Improvement in saw sets	John Smith	Philadelphia, PA
150,678	May. 12, 1874	Improvement in handsaw handles	Christopher Eisenhardt	Philadelphia, PA	Advertised as a element of Disston and Sons' New Patent Skew Back Hand Saws. The design facilitates the use of the thumb of the left hand to assist in sawing, especially ripping.
150,723	May. 12, 1874	Improvement in circular-saw machines	John Smith	Philadelphia, PA
151,363	May. 26, 1874	Improvement in Saws	Henry Disston	Philadelphia, PA	Handle is designed to to be grasped by one hand (four fingers) and shaped to allow the other hand to also grasp the saw. Blade has a slot and enlarged hole to facilitate removal/replacement of the blade. Sold by Disston as their Nest of Saws in the 1876 Price List. The handle design utilized was the more conventional compass saw handle ('pistol') design.
151,818	Jun. 09, 1874	Improvement in Handsaws	George Abrams	Philadelphia, PA	Frame and bar arrangement that allows the blade to be curved for cutting a curved line.
152,347	Jun. 23, 1874	Improvement in Handsaws	Henry Disston	Philadelphia, PA	Skew back handsaw. Changing the back from straight to skew reduces vibration of the saw and it makes the saw less likely to jar the operator causing kinks.
157,634	Dec. 08, 1874	Improvement in handles for saws	William J. Reagan	Royersford, PA	Recess for thumb - right hand only. Primarily used on the Disston No 9 improved backsaw and also occasionally found on Disston's No 4 backsaw models. Unknown if the the use on No 4s was a catalog item or a special order. Early handles have the patent number stamped near the recess. Reagan also held a patent 154,904 an improved casting for school desk arms. The patent specification gives the patentee's location as "Royer's Ford" rather than the usual spelling of Royersford.
163,162	May. 11, 1875	Improvement in Saw Sets	Henry Disston	Philadelphia, PA	Handled saw set/saw wrest designed to accomodate teeth of different thickness by utilizing a revolving disk with openings corresponding to the blade thickness along with set screws to secure the disk as well as limit the set. Known examples are marked H. DISSTON & SONS/PHILADA and PATENTED./MAY 11.1875.
163,163	May. 11, 1875	Improvement in Saw Gummers	Thomas S. Disston	Philadelphia, PA
167,996	Sep. 21, 1875	Improvement in Handsaws	Henry Disston	Philadelphia, PA	Patent for Disston's cover top design
169,343	Nov. 02, 1875	Improvement in Saw-Bucks	Henry Disston	Philadelphia, PA	Sturdy saw-buck that is easily taken apart and stored in a compact space. Available in the 1876 Disston Price List although the patent is not referenced.
172,392	Jan. 18, 1876	Improvement in saw-gummers	John Connor	Philadelphia, PA	An example of this saw gummer has been seen, marked "DISSTON & SONS / PATENTED JAN 18TH 1876".
177,481	May. 16, 1876	Improvement in insertable saw-teeth	Henry Disston	Philadelphia, PA
178,123	May. 30, 1876	Improvement in insertable saw-teeth	Thomas S. Disston	Philadelphia, PA
181,422	Aug. 22, 1876	Improvement in Handsaws	Henry Disston	Philadelphia, PA	A hole thru the blade facilitates a screw/bolt to secure the blade to the back of a backsaw as either a "U" shaped clamp or as part of the frame. Would prevent the blade from working its way out of the metal back as is sometimes encountered with backsaws. Known example with closed handle but apparently a short lived design.
		Improvement in Handsaws	Charles T. Shoemaker	Philadelphia, PA
181,421	Aug. 22, 1876	Improvement in tabs for gang-saws	Henry Disston	Philadelphia, PA
181,650	Aug. 29, 1876	Improvement in Saw Blades	Henry Disston	Philadelphia, PA	Handsaw blade's double taper is accomplished by rolling rather than previous method of grinding which wasted metal and reduced toughness of the blade.
181,648	Aug. 29, 1876	Improvement in Securing Saw-Handles to Blades	Henry Disston	Philadelphia, PA	The heads of the saw screw and nut are slightly domed, and their outer edges beveled so that they flare outward toward the face. Additionally, the screw is received by a blind threaded socket in the tubular projection of the nut. The tubular projection may, or may not, be long enough to engage the saw blade. Disston expresses a preference for those which are long enough to engage the blade. The overall purpose of this patent is to allow the handle and the saw nuts and screws to be finished and polished prior to assembly, with the beveled edges of the bolts/screws forming their own seats in slightly undersized shallow holes bored into the handle. This also allows for the saw nut to be subsequently tightened without altering appearances. Saw nuts based on this patent were cast, making them relatively expensive to produce. Additionally, the shafts were relatively thin, so were prone to twisting off. In time, they appear to have been superceded by Glover's patent (375350). Figures 4 & 5 of the patent drawing were added to illustrate the common "split nut" arrangement which Disston intended to replace.
183,805	Oct. 31, 1876	Improvement in Methods of Attaching Saws to Handles	Joseph Holden	Middletown, NY	Handle with thumbscrew to allow a slotted blade blade to be inserted/removed. Slot in handle allows the blade to be placed in four different positions. Initially produced by WM&C and later offered by Henry Disston & Sons as the No. 70 Holden Pattern Compass Saw.
188,243	Mar. 13, 1877	Improvement in Wrenches	Willis D. Gold	Philadelphia, PA	The tool is a steel bitted screwdriver, with the malleable iron handle containing several wrench openings on the sides and end. It is called an improvement on Gold's May 14, 1867 patent (no. 64,662). One version of the tool may have been a tool kit screwdriver for Domestic sewing machines. According to Ken Cope's "American Wrench Makers 1830-1930" H. Disston & Sons of Philadelphia produced this as the Excelsior Wrench and Screwdriver.
188,604	Mar. 20, 1877	Improvement in Combined Pruning Shears and Saw	Thomas S. Disston	Philadelphia, PA
189,199	Apr. 03, 1877	Improvement in insertable saw-teeth	Thomas S. Disston	Philadelphia, PA
192,240	Jun. 19, 1877	Improvement in circular saws	Henry Disston	Philadelphia, PA
194,659	Aug. 28, 1877	Improvements in Saw Handles	Henry Disston	Philadelphia, PA	Keyhole style metal saw handle. Known examples have the patent date cast into the handle. Interesting to note that this appears to be one of the few patents that Henry Disston assigned to his brothers but perhaps only as a result of the dual inventor status.
		Improvements in Saw Handles	John Vandegrift	Philadelphia, PA
201,276	Mar. 12, 1878	Improvement in Spirit Level and Plumb	Joab Morss	Philadelphia, PA	Adjustable level and plumb. Bearing point is rigid while the adjusting screws act directly on the vial casing which is claimed to provide a more certain and delicate adjustment than adjustments provided by springs or spring arms. Known example marked with patent date and R & E MNFG Co.
282,304	Jul. 31, 1883	Saw set	James Garland	Philadelphia, PA
288,807	Nov. 20, 1883	Try Square	Robert Hodges	Philadelphia, PA	Sold by Disston and Son's as the #1 1/2 iron square, Sample marked 'Patented Jan. 06,1885, also Henry Disston and Sons.' unable to find a connection to the date and tool at this time.
298,709	May. 13, 1884	Saw	John Smith	Philadelphia, PA
310,420	Jan. 06, 1885	Combination Gage	Andrew J. Hellings	Philadelphia, PA	Robert C. Barrie - patent attorney From about 1885 to 1910, Disston made a variety of Machinist's tools. This invention relates to that class of devices, which are used by mechanics in truing up work of different forms, and it has for its object to furnish a gage for square corners, hexagonal corners, and equilateral triangles, for finding the center of a square, for measuring the angle of a center hole, and for measuring the depth of apertures. I am aware that gages for trying squares and angles of sixty degrees, also narrow rules for measuring, are common.
311,435	Jan. 27, 1885	Saw	Almon Lord	Brooklyn, NY	Metal strap is riveted to the blade and attached to the handle by screws. Very similar to, and references Hankin's patent 295,385, with the exception that the metal "clamps" the handle by extending past the top surface to embrace a portion of the handle side. Originally produced by Harvey W. Peace Co. and marketed as the "Vulcan" and later produced by Henry Disston and Sons as the D-24 Pruning Saw.
326,798	Sep. 22, 1885	Saw with insertable teeth	John Smith	Philadelphia, PA
367,605	Aug. 02, 1887	Saw	Thomas S. Disston	Philadelphia, PA
375,350	Dec. 27, 1887	Saw Screw	Charles Glover	Hartford, CT	The primary focus of this patent is on the two-part construction of the saw medallion ("label screw"). In a sense, it can be seen as an improvement on Munger's patent (U.S.P.N 98180), which had no provision for preventing the shaft from twisting independent of the head if the swaged fit failed. The large show surface of Glover's medallion, in conjunction with the shoulder beneath it, allowed for the addition of longitudinal ribs on the shaft of the screw to resist turning. The medallion (figures 2, 3 & 4) and the saw screw (figure 5) shown in Glover's patent drawings both feature the internally threaded construction patented by Henry Disston in 1876 (U.S.P.N. 181648). This form displaces the through screw and "split nut" arrangement which had been the norm. Glover's saw screw differs from Disston's by being formed in a die rather than being cast and having longitudinal ribs on the shaft rather than a square section to resist turning. Also, though not specified in the patent, the shafts of Glover's saw nuts were of stouter construction. Glover's form eventually superseded Disston's. Saw medallions with this patent date have been found on saws from a wide variety of saw manufacturers.
395,218	Dec. 25, 1888	Handle for Crosscut-Saws	Christopher Eisenhardt	Philadelphia, PA
412,024	Oct. 01, 1889	Device For Inserting Saw Teeth	Thomas S. Disston	Philadelphia, PA	The wrench has a pin that fits in a hole in the tooth, and lugs that bear on either side of the cutting tip of the tooth. It conforms to the form of insertable teeth used in Disston circular saws of the period.
429,019	May. 27, 1890	Saw-gumming machine	Thomas S. Disston	Philadelphia, PA	This patent gummer was featured in the 1895 catalog from Montgomery Ward as "Disston's Patent Self Feeding Saw Gummer. Showing the Victor in position for work on a 60-inch circular saw..."
482,572	Sep. 13, 1892	Saw Filing Machine	Thomas S. Disston	Philadelphia, PA
495,931	Apr. 18, 1893	Handsaw	Thomas S. Disston	Philadelphia, PA	Compass saw with removeable handle that requires no tools to attach and detach.
510,846	Dec. 12, 1893	Saw Sharpening Device	Thomas S. Disston	Haddonfield, NJ	Combination saw vise and frame to hold and guide the sharpening file.
530,793	Dec. 11, 1894	Metal Saw	Matthew Odgers	Philadelphia, PA	Metal cutting saw with adjustable and removeable teeth. Blade has a series of sockets to receive the teeth and with a transverse holes to receive the securing pins for the teeth.
607,712	Jul. 19, 1898	Strainer-Rod for Wood-Saws	William Smith	Philadelphia, PA
		Strainer-Rod for Wood-Saws	Edwin F. Shaw	Philadelphia, PA
628,775	Jul. 11, 1899	Cane Knife	Henry Disston	Philadelphia, PA	Corrugations are used on the portion of the blade that is close to and secured by the handle. Claims to overcome the problem of light cane knifes of breaking at the handle and with the corrugations the additional strength afforded, allows the design to remain light (and be able to be used by women and children).
636,168	Oct. 31, 1899	Saw Set	Matthew Odgers	Philadelphia, PA	Sold as Disston's Triumph Saw Set and kept in production until the 1940s.
643,914	Feb. 20, 1900	Trowel Grinding Machine	Edwin F. Shaw	Philadelphia, PA	Machine for grinding multiple trowels in one operation.
D33,617	Nov. 27, 1900	Design for a Saw Handle	Edwin F. Shaw	Philadelphia, PA	Patent term is for 14 years. Claimed essential feature is the handle having laterally extending flanges at the upper and lower edges of the handle. Clearly a handle that would be constructed of metal or plastic material.
684,729	Oct. 15, 1901	Saw Handle	Edwin F. Shaw	Philadelphia, PA	Design utilizes two piece, sheet metal construction with the intent of producing a handle that can be subjected to dampness and can be sterilized.
687,583	Nov. 26, 1901	Saw Handle	Edwin F. Shaw	Philadelphia, PA	Improvement over Shaw's 684729 patent for a metal handle saw. It appears that the improvement is the inclusion of internal flanges at the upper and lower edges, the handhold, and depressed flanges forming the recess for the back of the saw.
687,584	Nov. 26, 1901	Saw Handle	Edwin F. Shaw	Philadelphia, PA	Complementary patent to his patent 687584 for a butcher saw handle. Continuation from his earlier metal handle patent, 684729. In this patent instead of two mirror image pieces, the two pieces consist of a body section and a handle section that are joined together.
689,135	Dec. 17, 1901	Knife Handle	Edwin F. Shaw	Philadelphia, PA	Handle is made of metal to allow the entire knife to be sterlized without destroying the handle.
D35,483	Dec. 24, 1901	Design for a Crosscut-Saw Handle Member	Leonard Shallcross	Philadelphia, PA	Patent is for 14 years. Known example on 36" saw is marked on the metal curved rod - PAT'D DEC.24.1901.

816,433	Mar. 27, 1906	Side Dressing Tool for Saw Teeth	Richard C. Charlton	Philadelphia, PA
846,196	Mar. 05, 1907	Insertable tooth for metal saws	Samuel Freas	Trenton, NJ	This insertable tooth design was intended for metal-cutting saws. An ad in the 1912 "Disston Lumberman Handbook" features the "Disston Premier inserted tooth metal saw. Patented March 5th, 1907. Alternating round and oval-top teeth. Inverted wedge. Diameters from 18 inches to 60 inches. The fastest cutter and most durable saw of the kind ever made."
869,851	Oct. 29, 1907	Bevel	Ernest A. King	Philadelphia, PA	Blade is secured in position by use of a steel ball being pressed against a bevel on the screw holding the blade drawing it tight. In the event that the steel ball is lost, the screw at the head of the bevel can be used to lock it into place.
876,720	Jan. 14, 1908	Level	Ernest A. King	Philadelphia, PA
919,883	Apr. 27, 1909	Square	Ernest A. King	Philadelphia, PA	Traditional cabinetmakers square where the blade and stock is made of one piece in order to keep it square in spite of rough handling. The brass face of the square is attached to the wooden scales without weaking the scales as the pins are wedged into the slot between the scales.
938,680	Nov. 02, 1909	Adjustable and Detachable Handle for Saws	Robert E. Martin	Newark, NJ	Nine claims for this patent although essentially means to easily attach/detach saw blades and adjust the angle of the handle. Serations on the blade and handle to assist in positioning. Applicable to both traditional handsaws and compass saws. Similar to the patent, 885521, used by Bishop and Simonds with the main visual difference the use of single blade tightening nut on the former and a more conventional two bladed (wing) tightening nut on the latter. Manufactured by Henry Disston & Sons, Richardson Bros, and Atkins.
