ANDREW TRACY, OF POUGHKEEPSIE, NEV YORK.
MACHINE FOR CUTTING SHEET METAL.
Specification of Letters Patent No. 2,181, dated July 17, 184:1.
To all whom t may concern Be it known that I, ANDREW TRACY, ot the village ot Poughkeepsie, county of Dutchess, and State ot New York, have invented a new and useful machine tor cutting sheet tin, copper, brass, iron, or any sheet metal and glass, which machine I denominate the rotary and graduating circular hing shears and press, and l dohereby declare that the following is a full, clear, and exact description of the const-ruction and operation of such machine, (reterence being had to the annexed drawing making part of this speciticatiom) in which- Figure I is a perspective view of the entire machine;
Said press or machine being a cast iron trame with a screw or lever power worked by hand, (marked A, on the drawing,) which power on being applied brings the two circular holding plates marked a, a, together, thus secu-ring the sheet of metal or glass, lirmly for shearing',
To theI upright cylindrical sections of the machine exhibited in detail and marked s, s, (Figs. 2, and 6,) the circular holding plates are tixed, and attached to the interior ot said cylindrical sections is a graduated rod or lever marked B, in which the shears marked b, 7). are secured for operating, and by means of a thumb screw used for :tastening the saine on the said lever, made to cut the metal or glass at any given diameter.
Two distinct modes oit operation in shearing or cutting' the metal or glass are contemplated, viz: First. that the shears be moved round by hand, being fixed on the .lever so as to cut the metal or glass at the required diameter, the holding plates, and metal or glass shut therein contained, being tixed and stationary. Second, the material to be cnt being secured as above, the holding plates with the material therein, are made to revolve by the use ot the lever and ratchet, represented in parts by Figs. 3, 4e, and 5. The thumb screw ot the shears marked C, being turned prior to each movement or operation, until t-he cutters marked fZ, (Z, are forced through the metal sheet, or into the glass, (a diamond or diamonds being employed in the cutting, or shearing ot glass.) The tirst mode of operation is deemed most feasible when the material, (whether metal or glass,) to be cut or sheared is comparatively thin and light; the second mode ot operation, may be preferable when the material is of a thick and stubborn texture. The upright cylindrical .sections with the circular holding plates, their internal structure and movement are represented by figures marked 2 and G: E is the lower, F, the upper center of said sections; G is the worm spring to raise the upper section in order to liberate the metal or glass from the holding plates after the shearing process.
The shears consist of two sections or parts united b v a hinge at one end; at the other end ot the shears are fixed the circular cutters marked CZ, (l, which cutters when the shears is in operation revolve on screw pins, there being one ot such pins in each jaw of the shears. The cutters being forced through the material to be sheared as above stated.
What l claim as mv invention and desire to secure by Letters Patent, is-
1. Att-aching the upper rotary-shear, to a hinge piece, regulated by a thumb screw, tor the purpose and in the manner specitied.
2. Attaching the stock of the shears to a lever revolving around the center of the holding plates.
And the combination of the lever and ratchet, with the upper holding plate, for turning the metal or glass as herein described.
Dated Poughkeepsie July 3d 1841.
ANDREV TRACY.
