PUNGHING MAGHINB.
Patented Oct. 19, 1886.
Witwe/sooo f v 3513 q awww Sgo STATES UNITE ATnNT FFICE@ PUNCHINGIVIACHINE.
SPECIFICATION forming part of Letters Patent No. 351,340, dated October 19, 1886.
Application tiled June 9, 18:16. Serial No. 201,594. (No model.)
To @ZZ whom t may concern.-
Be it known that I, Ciras'rnn Rollen, of Minneapolis, in the county of Hennepin, State of Minnesota, have invented a new and useful ImprovementinPunching-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speciitication, in which- Figure I is a perspective view of apunching-1nachine embodying my improvement. Fig. 2 represents details of the two-part head or plunger.
My invention relates to certain improve ments in punching-niachincs especially adapted for the use oi' tinners and sheet-metal workers; and it consists in the construction and combination of elements hereinafter described and specifically claimed.
'Io enable others skilled in the art to make and use my invent-ion, I will proceed to describe the manner in which I have carried it out.
In the said drawings, A represents the main frame or casting of a punchingmachine ot' any weltknown and suitable construction. Il represents the usual operating-lever, journaled in bearings in the front of the traine, and having itsrear end attached to a spring, C, as shown in Fig. If Upon a ledge, a, projecting from the main trame, is swivelcd or otherwise secured to rotate a standard, D, in the upper slotted end of which isfulcrumed the upper lever,E, by which power is applied to operate the leverB and its adjuncts. rIhe rear end ofthe lever B engages the head b of a threaded bolt, F, the shank of which also passes through the lever E, and is secured by suitable adjustingnuts, as shown. From this description it is evident that by swiveling the standard D, I am enabled to throw the lever in or out, as desired.
In the front portion of the main frame is located the plunger G, which carries the punch. This plunger is formed in two parts, d and c, connected together by screws f, whereby the section l may be removed when it is desired to take out a broken punch, or for 'any other similar purpose. The section c is provided with ribs g, which engage grooves in the sides of the frame A, thereby forming guides in which the plunger vertically reciprocates during the movements ofA the machine. By reference to Fig. 2 it will be observed each of the sections d c, which form the plunger, are provided with seinicircular grooves Z, having threads corresponding with the size and pitch of the thread on the shank of the'punch. This punch II is a steel punch, and has the usual punchingface and an integral threaded stein or shank, which passes through the threaded opening formed by the groovesl, and at its extreme upper end is provided with a squared portion adapted to receive a wrench or equivalent tool, whereby the punch is adj usted within the plunger until its punchingt'ace is at the proper distance vtroni the die m, as shown in Fig. l.
IIaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. In a punchingmachine, the main frame A and operating-lever E, in combination with a standard, D, swivelcd or otherwise secured to rotate upon the main frame, a lever, E, fulcrumed within the slotted upper end ot' the standard, a connection between the rear ends otl the said levers, and a reciprocating plunger carrying the punching-tool, substantially as described.
2. In a punching-machine, the main frame and the levers B and E and connections, in combination with a reciprocating plunger mounted in said trame and having a threaded opening, and a punching-tool having a threaded shank adjusted within said opening, substantially as herein described.
3. In a 1)L1ncliing11iacl1iiie, the frame A,
having grooves formed in its front portion, a
reciprocating two-part plunger sliding within said grooves, and having a threaded semicircular groove, l, formed in each part, a punch passing through said plunger, and having a threaded shank engaging the threads in the grooves, whereby the punch is adjusted, and screws for securing the two parts ofthe plunger together, substantially as described.
4. In a punching-machine, amain frame, in combination with a plunger formed in two sections, each section of which is provided with a seinieircular threaded opening, and a punching-tool having a punching-face and an integral threaded shank engaging the threads in the grooves, whereby the tool is adjusted, substantially as described.
