Patent Number Date Title Name City Description
73,431 Jan. 21, 1868 Screw Cutting Tool Edgar B. Beach West Meriden, New Haven County, CT This patent was improved with patent #150,276.

Abstract:
his invention, though designed particularly for" a screw-cutting tool, may be applied to tools for general turning, the object being to construct a cutter which shall retain its form without being "reset" every time it is ground, and thus avoid the necessity of employing the most skillful workmen for this class of work; and the invention consists in a cutter formed so as to be attached upon one side of the thank, and inclined in the said shank so that the face or edge of the cutter will be at the proper angle to the work to be done, and so that by simply grinding the upper end of the cutter the tool will be sharpened, and the said shank provided with a device for securing the cutter upon the said one side.
Claim:
The cutter A, provided with the flange B, attached to one side of a shank
115,678 Jun. 06, 1871 Improvement in Pipe-Wrenches William Henry Barwick QC, Canada The shape of the hook jaw allows each size of wrench to grasp a range of pipe sizes. Hardware trade ads also show the wrench used on square and hexagon nuts. The specifications describe it as an improvement on Robert Bain's April 9, 1867 patent (no. 63,689), and Henry Getty's Jan. 13, 1863 patent (no. 37,395).
A Canadian patent 909 was issued for this wrench on April 4, 1871.
By 1876, Billings & Spencer had "purchased the entire stock, machinery, patent rights and good will" of the Barwick Wrench Company.
150,276 Apr. 28, 1874 Metal-Turning Tools Edgar B. Beach West Meriden, New Haven County, CT Abstract:
his invention relates to an improvement in he screw-cutting tool for which Letters Patent #73,431 were granted to me January 21, 1868; and, though designed particularly for screw-cutting, may be applied to tools for general turning. In that patent the cutter was secured by a clamping device dependent upon the friction o hold the cutter. In practice it has been found that the cutter is liable to be forced down or moved in its seat. The object of this invention is to avoid the possibility of slipping; and it consists in combining, with the shank fitted to receive the cutter in a recess upon its side, a cutter and clamping-piece with corresponding irregular sur- faces, so as to prevent the movement of the cutter in the direction of its length.
Claim:
The cutter A and the shank B, fitted to receive the said cutter, combined with the clamping-piece C and bolt D, the said piece C and the rear side of the cutter made irregular in form, so as to interlock.

915,012 Mar. 09, 1909 Drop Press and Attachment Therefor Louis Garfield Bayrer Hartford, CT H. E. Hart - patent attorney
As is well known, in machines of this character the upper die is raised to the top of the machine and after a piece of metal has been placed on the lower die the upper die is released and allowed to drop, operating in conjunction with the lower die to form the piece of metal to the desired shape. This upper die is fastened in a hammer which is secured to a board, and suitable rollers, operated by cams, are brought into engagement with this board, after the hammer has dropped, to raise it to the top of the machine. The tripping mechanism which throws these rolls into engagement with the board is actuated by the hammer when it reaches the bottom of its stroke and it is a novel form of tripping mechanism which constitutes the herein described invention.
956,280 Apr. 26, 1910 Wrench George Bryar Boston, MA The long slot in the handle provides the spring action to allow the alligator wrench jaws to grip and release pipe.
Compare this to Frederick E. Walden's March 9, 1920 patent (no. 1,333,517), produced as the WAL-PAT pipe wrench.

1,929,021 Oct. 03, 1933 Multiple Roll Set Board Drop Hammer Michael H. Flynn Hartford, CT Jeffery Kimball Eggleston - patent attorney
The object of the invention is an improvement in the mechanism for causing the lifting rolls of the several sets to bear simultaneously and equally upon the hammer board. These rolls and their supports and the members which move the latter are ponderous structures but are required to move quickly into and out of board-gripping position and some considerable difficulty has been encountered, under these conditions, in causing them to exert substantially equal pressure on the hammer board as well as in causing them to release the board simultaneously. Failure of the rolls to act in close unison when engaging, as well as when disengaging, the board interferes with sustained reciprocation of the hammer, besides inuring and shortening the life of the board. The present invention overcomes the difficulties referred to, by the use of mechanism simple in form and the least subject to derangement, under the severe conditions of drop hammer use.
