Patent Number	Date	Title	Name	City	Description
8,881	Apr. 13, 1852	Feed apparatus of planing-machines	Joel Whitney	Winchester, MA	Extended 7 yrs, reissued twice. This patent was acquired by S. A. Woods, but it may first have been used by James A. Woodbury, who worked for Joel Whitney in two separate stints in his career, and is known to have sold his woodworking machinery business to S. A. Woods.
11,984	Nov. 21, 1854	Presser-bar for planing machines	Harvey Snow	Dubuque, IA	According to the 1873 "Subject-matter index of patents for inventions issued by the United States Patent Office", this patent was granted an extension.
20,527	Jun. 08, 1858	Planing-machine	James A. Woodbury	Winchester, MA
21,474	Sep. 07, 1858	Journal-box	Harlow W. Thayer	Sandwich, MA	This patent was reissued and also granted an extension.
26,902	Jan. 24, 1860	Planing machine	Solomon S. Gray	Boston, MA
43,074	Jun. 07, 1864	Improvement in barrel-machines	R. W. George	Richmond, ME	Co-assignee Gray was co-founder of Gray & Woods, but it appears that by the time of this patent he was no longer in partnership with S. A. Woods.
55,389	Jun. 05, 1866	Improvement in planing-machines	John B. Tarr	Chicago, IL	This important patent is for a side-head chip breaker. It prevents splintering of the side of the board while being matched. It is an improvement to patent 20,527. Unfortunately for inventor John B. Tarr, this patent's claims were considerably narrower than they could have been, which left room for manufacturers to put chip-breakers on their planer side-heads without having to pay any licensing fees. This issue is discussed in Charles Tompkins' book, "History of the Planing Mill".
56,656	Jul. 24, 1866	Improvement in planing-machines	James A. Woodbury	Boston, MA
RE2,676	Jul. 09, 1867	Planer	Joel Whitney	Winchester, MA	Extended 7 years (from Scientific American 1867-07-27).
RE3,110	Sep. 01, 1868	Planer	Joel Whitney	Winchester, MA
81,953	Sep. 08, 1868	Improved mechanism for operating the beds of planing-machines	Henry F. Shaw	West Roxbury, MA	J. H. Adams - patent attorney Like the immediately preceding patent 81,952, this patent is of interest because the two assignees were both important machine inventors and builders in their own rights. My invention relates to the application, in such-machines, of a differential gear, in connection with an eccentric-shaft or sleeve, operating together upon the principle described in the patent, No. 64,915, granted to me on the 21st May, 1867. In my present improvement, a cylinder, having a spur-gear upon its internal surface, is fixed to the shaft which moves the bed of the planing-machine, upon which spur-gear rolls-a second cylinder, with a spur-gear upon its external surface, and hung upon a sleeve arranged eccentrically on the shaft which carries the first named cylinder. The cylinder with the external gear is prevented from rotating, but is allowed an oscillating movement by means of an arm attached to it, and, extending a short distance, is provided with a slot, at its end, which plays upon a pin attached to the side of the frame of the machine. The rotation of the eccentric-sleeve imparts a motion, to the cylinder having the external gear, and the teeth of the latter, engaging with the internal gear, impart a motion to the latter, the amount of motion depending upon the difference of the relative diameters of the two pitch-lines of the spur-gears.

		Improvement in planing-machines	Solomon A. Woods	Boston, MA
134,596	Jan. 07, 1873	Improvement in machines for jointing staves	Solomon S. Gray	Boston, MA
RE5,323	Mar. 11, 1873	Improvement in journal-boxes	Harlow W. Thayer	Sandwich, MA	This patent was extended and reissued. The original patent was co-assigned to Woodbury and Solomon A. Woods but this reissue was assigned to Woodbury and Thayer.
142,460	Sep. 02, 1873	Improvement in planing-machines	William H. Gray	Boston, MA	Invention is a means of linking the ends of the feed rollers in such a way as to keep the rolls parallel to the bed. Otherwise, stock fed off-center will experience uneven pressure.
142,936	Sep. 16, 1873	Improvement in planing-machines	Solon W. Nelson	Worcester, MA	For integral sharpener etc. This patent date was seen on an S. A. Woods planer. There is no direct evidence that this is the correct patent, but it is, by far, the most likely candidate.
161,726	Apr. 06, 1875	Improvement in planing-machines	George E. Woodbury	Cambridge, MA	An 1888 S. A. Woods catalog shows this patent date, and this Woodbury patent is the most likely candidate, especially since Woodbury and Woods received a joint patent a few years before (patent 117,230).
188,469	Mar. 20, 1877	Improvement in copying-presses	Richard E. Kidder	Worcester, MA	This patent is of interest in relation to woodworking machinery: the inventor was a manufacturer of woodworking machinery, and the assignee was, or would become, vice-president of woodworking machinery maker S. A. Woods Machine Co.
237,652	Feb. 08, 1881	Cutter-head for wood-working machines	Solomon A. Woods	Boston, MA
244,507	Jul. 19, 1881	Planing-machine	Solomon A. Woods	Boston, MA	This is the first double surfacer with endless-bed infeed and power-driven top and bottom outfeed rolls, and this type of machine became very popular in the following decades.
303,179	Aug. 05, 1884	Cutter-head	Martin Murphey	Brooklyn, NY	Co-assignee Joslin was vice-president of S. A. Woods Machine Co., and head of their New York branch. This is one of several patents granted or assigned to Joslin; it appears that S. A. Woods' New York branch was run as a separate business, and these patented inventions were developed independently of the parent company. We have not been able to find any information connecting the other assignee, Albert Johnson, to S. A. Woods Machine Co., although the search is hampered by the commonness of Johnson's name.
313,497	Mar. 10, 1885	Loose Pulley	James A. Horton	Reading, Middlesex County, MA
340,444	Apr. 20, 1886	Resawing machine	Isaac R. Joslin	New York, NY	Ad in May 1887 issue of Carpentry and Building: "Joslin's patent re-sawing machine, with segment saw. The best in the market. For sale by the S. A. Woods Machine Co." The saw is labeled with this patent date and "I. R. Joslin, N.Y." The inventor was a long-time employee of the S. A. Woods Machine Co., and by the time of this invention he was vice president of the company and head of their New York operations. Given all this, and the fact that this patent is not assigned to S. A. Woods Machine Co., it seems most likely that Joslin developed this machine on his own time, patented it, and then licensed it to his employer. In August 1886, only four months after this patent was issued, Joslin retired due to failing eyesight. He died of complications from typhoid in October 1889, age 56. At the time of his death he was working toward starting his own woodworking machinery manufacturing business.

374,283	Dec. 06, 1887	Planing machine	John R. Thomas	Boston, MA	This patent was a "Daniels and Woodworth planers combined", and can plane "three times as rapidly as the Daniels". A Daniels planer has a travelling bed to which the stock is shimmed and dogged to hold it firmly. The cutterhead consists of an arm that rotates horizontally above the stock, with a cutter mounted on each end of the arm. Where the Woodworth planer makes one face parallel to the opposite face, the Daniels planer makes the upper face flat and parallel to the bed.

483,970	Oct. 04, 1892	Planing-machine	John R. Thomas	Boston, MA	This invention relates to planers having cutters both above and below the stock. The under cutter is typically placed well beyond the upper cutter, but if there are any protrusions in the bottom of the board, then the stock lifts up while passing below the upper cutter, creating an uneven thickness. The innovation is to use a "preparatory under cutter to rough off or true up the under surface of the board or stick by removing any knots or projections therefrom before it arrives at the surface-plate below the upper cutter".

Nichols Machine Works, where it seems to have been their biggest-selling product. In early 1899 they sold all rights for that machine to the S. A. Woods Machine Co. The 1899 S. A. Woods catalog features the No. 211 Lock Corner Box Machine that carries this patent date plus the date for patent 593,551. The description says, "We present to the attention of progressive box manufacturers the well-known Nichols Lock Corner Machine, the patents, patterns, good will, etc., of which we have recently purchased from the inventor." This machine was not shown in the 1898 S. A. Woods catalog.

1,041,234	Oct. 15, 1912	Automatic Feeding Table	Charles W. H. Blood	Winthrop, Suffolk County, MA	George L. Maxwell - patent attorney This invention relates to feeding mechanism for advancing pieces of stock in a continuous line to a machine, for operating, thereon and, while having other, and more general fields of usefulness, is especially designed to cooperate with a planer or like machine to automatically feed a continuous line of boards or other steely to the machine. A principal object of the invention is to provide a mechanism adapted to receive boards or other stock supplied therein irregularly, for example, in intermittent) bunches or carelessly, and to automatically take the boards one by one and feed them in proper alignment to the planing mechanism, with the forward end of each board always abutting against, the rear end of the preceding one so that an uninterrupted line to the planer heads is maintained. The invention provides means to insure that only one board shall be advanced to the planer mechanism at once and adjustments are provided to accommodate beards or other stock of varying widths and thicknesses. In carrying out my invention I connect the automatic feeding mechanism for operation in timed relation to the planer and I preferably connect the driving connections so that the feed mechanism of the feeding table over runs the drive or receiving capacity of the planer, say about twenty per cent., so that the succession of boards being fed are always closely pressed and abutted, end to end as is requisite in the high speed planer operations now in common use.

This patent was subsequently improved in a patent, 1,679,457, that was assigned to H. C. Dodge, Inc. of Boston. Mr. H. C. Dodge was the president of woodworking machinery maker S. A. Woods Machine Co., and H. C. Dodge, Inc., was bought out by S. A. Woods Machine Co., and therefore this patent was used on motors for woodworking machinery. Patent 1,805,437 was co-invented by John B. Wiard and assigned to S. A. Woods Machine Co.

1,679,457	Aug. 07, 1928	Dynamo-electric machine	John B. Wiard	Lynn, MA	"This invention relates to dynamo electric machines and more particularly to improvements designed to dissipate the heat arising from internal losses in such machine. The invention has for its object the provision of an effective cooling or ventilating system embodied in the machine itself in simple, compact form particularly, though not exclusively, intended for high speed direct-connected, induction motors where the constructional features render the ordinary methods of cooling impracticable... one embodiment of the invention in an alternating current motor of the induction type which is mounted on the frame of a wood-working machine directly connected to drive a working part thereof, such as the cutter head 5." Harry C. Dodge was later the president of S. A. Woods Machine Co., and it is my hypothesis that he started as a motor manufacturer with his own firm and was subsequently bought out by S. A.

1,681,793	Aug. 21, 1928	Flexible coupling	Amos P. Steiner	Waynesboro, PA	This flexible coupling consists of a pair of plates, each with a circle of pins, so that the circle of one set of pins fits completely within the circle of pins on the other plate. Then a rubber or leather band is snaked sinusoidally around the pins, providing the flexible coupling between the plates. This invention has been seen on various woodworking machines, and has also been seen in a catalog from the S. A. Woods Machine Co., labeled as the Woods Flexible Coupling.

1,773,712	Aug. 19, 1930	Apparatus for controlling electric motors	John B. Wiard	Lynn, MA	"This invention relates to apparatus for co-ordinately controlling the starting of different motors of a group so as to automatically prevent the operation of some one or more motors, or of devices driven thereby, during the period that one or more other motors of the group are being started and brought up to speed... As a specific illustration of such a case there may be instanced the use of motors in a wood-working machine where one motor is employed for driving the feed mechanism and a number of other motors used for driving the cutting devices which cut or shape the work when the latter is fed within their working range." The inventor worked for motor maker H. C. Dodge, Inc., and later for woodworking machinery (and motor) maker S. A. Woods Machine Co.
