63,232	Mar. 26, 1867	Improvement in saws	James E. Emerson	Trenton, NJ	This is a very early patent for insertable saw teeth. The idea was already known at the time, but in earlier patents, such as 14,172, the teeth do not resemble modern inserted saw teeth.
66,692	Jul. 16, 1867	Improvement in saws	James E. Emerson	Trenton, NJ	An advertorial in the 1868-02-01 issue of Scientific American features this invention, complete with four engravings. The principle of this invention is that below each gullet there is a series of semi-circular holes. When a tooth is sharpened, the gullet is filed down to the next semi-circular hole. The semi-circle defines the bottom of the gullet, avoiding the stress concentration of a sharp gullet. This innovation was heavily promoted by the American Saw Co.

2,023	Feb. 03, 1873	Removable saw set socket	Charles H. Waterous	ON, Canada	It appears that this invention was the work of James E. Emerson, and the others were listed to get around the laws that made it difficult for non-Canadians to be granted Canadian patents. Wilkes and Waterous were partners in C. H. Waterous & Co., which in April 1874 became the Waterous Engine Works Co., Ltd., wholly owned by the Waterous family. The Waterous companies made a diverse line of products including sawmills, and presumably also including this saw set.

167,368	Aug. 31, 1875	Improvement in Pipe-Wrenches	George W. Waitt	Philadelphia, PA	One of the basic alligator wrench patents. Displayed at the 1876 Philadelphia International Exposition (that maker's name is variously spelled Flanigan, Flanagan, Flanagin ).. used by American Saw Co, Roebling, etc. for the traditional No. 1 alligator wrench which remained in production into the 1920s, as well as for larger sizes. Waitt devised an improvement to this wrench which received pat. no. 1,041,707 on Oct. 15, 1912.
170,833	Dec. 07, 1875	Improvement in crosscut-saws	James E. Emerson	Beaver Falls, PA	Insertable teeth for a crosscut saw.

280,793	Jul. 10, 1883	Pipe Wrench	A. Wells Case	South Manchester, CT	The wrench is a variant of the alligator wrench, with the toothed jaw face curved. This curvature makes the gripping edge of the teeth tangential to pipe circumference throughout the size range of the wrench. Comparable Canadian patent no. 17,229 gives the patentee's name as Alfred W. Case. The AMERICAN SAW Co. of Trenton, NJ produced this design as the FALCON PIPE WRENCH. A known example includes the patent date in the markings.
17,229	Jul. 12, 1883	Improvements in Pipe Wrenches	Alfred W. Case	Manchester, CT	Canadian patent for A.W. Case's alligator wrench produced as the FALCON PIPE WRENCH by American Saw. The DATAMP entry for U.S. patent no. 280,793 has additional information about production, etc.

358,772	Mar. 01, 1887	Saw	James E. Emerson	Beaver Falls, PA
362,661	May. 10, 1887	Wrench	William B. Risdon	Trenton, NJ	A pin on a spring lever on the side of the jaw fits into one of several slots in the shank to hold the adjustment. A June 4, 1887 "Scientific American" notice about this patent was reprinted in the December 1988 "Missouri Valley Wrench Club Newsletter."
411,190	Sep. 17, 1889	Combined Wrench and Screw Driver	Burr Albert Haines	Smithville, NJ	The screwdriver blade fits in a slot through the handle and shaft of the adjustable jaw. The specifications describe the method of assembling all the parts. A slot on the inside of the adjusting nut allows the screwdriver blade to be retracted when not needed, and a notch on the outside of the adjusting nut indicates when the slots are aligned. Appears in early 1890s hardware catalogs as the HAINES WRENCH. It is a 4 1/2 inch long pocket wrench.
417,468	Dec. 17, 1889	Saw Tooth	William E. Brooke	Trenton, NJ
425,371	Apr. 08, 1890	Pipe Wrench	Andrew J. Curtis	Monroe, ME	The jaws are held "open" by a spring between the sliding pivot point and the adjusting bolt. The action is similar to alligator wrenches of the period. The selling point was the ability to grip at the tip of the jaws and reach into tight quarters. Corresponding Canadian patent no. CA-36,762 (with assignment to Philo. C. Blaisdell of Carrollton, NY) was granted June 5, 1891. Late 1890s ads showed four sizes: 9, 15, 18, and 22 inch.
482,281	Sep. 06, 1892	Wrench	George B. Stevenson	Chicago, IL	The "tail" of the movable jaw is enclosed within the hollow shell which also holds the adjusting ring. All-metal and wood handle versions were produced. Advertised as the TRIUMPH PIPE WRENCH and the STEVENSON WRENCH. A 1906 catalog listing shows it as the STAR PIPE WRENCH.
486,758	Nov. 22, 1892	Wrench	William E. Brooke	Trenton, NJ	Combined pocket wrench and screwdriver for bicyclists. The screwdriver is slid in and out of the case and clamped in place by the set screw. The adjusting nut for the movable wrench jaw is stabilized by pins that fit in a groove. A known example was offered at auction in the fall of 2010. Brooke's parallel patent (no. 486,759) has a different arrangement for the screwdriver.
486,759	Nov. 22, 1892	Combined Wrench and Screw Driver	William E. Brooke	Trenton, NJ	Screw-adjust nut wrench and screwdriver. The shank of the movable jaw and the screwdriver are adjusted individually. Brooke's parallel patent (no. 486,758) with a sliding screwdriver held by a set screw was produced.
491,870	Feb. 14, 1893	Wrench	William E. Brooke	Trenton, NJ	An adjustable alligator wrench with a double-size box end. The movable jaw has a spring to hold it against the adjusting bolt.
499,162	Jun. 06, 1893	Bandsaw mill	Charles M. Emerson	Bay City, MI	Inventor Emerson was a partner in Emerson, Smith & Co., which made sawblades and saw-sharpening tools. So far as we know, that firm did not make machines so we do not know why Emerson patented a band sawmill.
		Bandsaw mill	James E. Emerson	Beaver Falls, PA
503,677	Aug. 22, 1893	Wrench	Samuel W. Putnam	Elizabeth, NJ	The patent describes three different linkages to allow limited motion between two alligator wrench jaws. The opening to accommodate several sizes of square nuts is incidental and not claimed in the patent.
504,518	Sep. 05, 1893	Method Of Making Wrench Handles	William E. Brooke	Trenton, NJ	The handle in question is for a combined wrench and screw driver. The metal blank is stamped; the blank undergoes subsequent folding and drop forging processes to form the finished piece -- a hollow handle with integral fixed jaw, and slots for adjusting nuts for the screwdriver bit and movable jaw of the wrench.
539,801	May. 28, 1895	Attachable saw-tooth	James E. Emerson	Beaver Falls, PA	We have seen an 1896 price list from Emerson, Smith & Co., a company that made insertable saw teeth among its products. This patent was granted to the co-founder of that firm yet it is assigned to competitor E. C. Atkins & Co. Was there a takeover, or had Emerson left his own company? We don't know.
D27,471	Aug. 03, 1897	Design For A Wrench	Samuel T. Freas	Trenton, NJ	Single alligator wrench opening, with tapered wrench slot in handle, and small screwdriver on end of handle. Some wrenches marked with the patent date do not have the screwdriver but otherwise conform to the design.
593,882	Nov. 16, 1897	Wrench	Samuel T. Freas	Trenton, NJ	A spring-tensioned bearing thrusts a friction-cone end of the adjusting nut into a conical socket to prevent accidental alteration of the adjustment.
D28,270	Feb. 08, 1898	Wrench	Samuel T. Freas	Trenton, NJ	The design is a single end alligator wrench. It was the "traditional" form used by successive manufacturers. Some early examples produced by American Saw Co. and Roebling include the patent date in the markings.
