COMBINED SHEARS AND PUNCHIN-G-MACHINE.

SPECIFICATION forming part of Letters Patent No. 362,468, dated May 3. 1887.

Application filed October 18, 1886. Serial No. 216,138. (No model.)

I To all whom it may concern.-

Be it known that I, JoHN STORIZ, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of 5 Pennsylvania, have invented certain new and useful Improvements in Combined Shearsand Punching-Machines, of which the following is a specification, reference being had therein to the accompanying drawings, wherein-- Figure l is a side elevation of a combined metal cutting or shearing and punching-machine embodying my improvements. Fig. 2 is a vertical" section through the punch and operating devices therefor. Fig. 3 is a longitudinal section of same. Fig. 4 is a side elevation of the machine, the reverse of that shown in Fig. 1. Fig. 5 is an elevation ofthe punch end of the machine with one of the rotating orv circular disks, with part of affixed eccentric to it detached therefrom. Fig. 6 is an elevation of rear side of said detached disk.

My invention has relation to combined metal shearing or cutting and punching machines of the form wherein the cutting devices are located at one and the punching device at the other end of the machine, both of which devices are operated simultaneously by a common driving mechanism; and it has for its object to provide a simple, efficient, powerful, and durable combined punch and shears which is easily operated either by hand or by power to cut or shear sheet metal or other material,

cut off round rods or bars, and to punch the metal, as desired.

My invention consists of the construction, combination, and arrangement of parts, as hereinafter more fully described and claimed, having reference particularly to a base-plate or support which has at one end a shear or cutting blade, and at its other end a chamber or bearing for a punch and its operating mechanism, and to a lever or arm pivoted to said plate or support, which has at one end a shear or cutting blade arranged to make a shear-cut with the blade on the base-plate, and at its other end a. slot and eccentric-connection with rotating disks for driving or operating the punching devices, whereby a movement of the punch-operating devices also produces a movement of said pivoted lever or arm to produce a shear-cut between the cutting-blades; to a punch having a connection with an eccentric composed of two parts, each connected to or formed on rotating disks coupled together and mounted in suitable bearings, and provided with a driving crank or handle, and to diamctrical slots in said rotating plates for an adj ustable engagement of the driving-handle with said plates.

In the drawings, A represents a bed plate or frame composed, essentially, of a standard, (1, having lateral projections or arms a and a. The arm a is shorter than the arm a, and to its upper edge, at its outer end, is screwed or otherwisesecured a cutting-blade, b. The end of the long arm a terminates in a circular chamber or ring, a, having on its lower side a cylindrical guide or opening, a", for a punch or like tool-holder, D. To the open sides of the ring a are suitably secured annular plates a, which form inwardly-proj ecting flanges for the sides of ring a, to provide bearings for rotating disks E E, which extend part way into the ring or chamber a and have shoulders or cap edges to, fitting over the annular plates 7 5 a, as shown more plainly in Fig. 2. Between these disks E E is an eccentric, F, which revolves with the disks; but, to provide for the rotation of the disks in unison with one another and to firmly connect them and'the (30- 8o centric F together, the latter is made in two parts-viz., a central oblong part, f, fittlng between two outside parts, f, see more plainly in Fig. 3)-the former of which is secured to or formed on disk E, and the latter is correspondingly-affixed to disk E, and through the center of disks E E passes a screw, f The screw f secures the disks together, while the interlocking of the separable parts f f f eccentric F provides for the disks rotating in unison.

The use of the separable or divided eccentric F admits of the employment of a continuous or one-part eccentric-strap, g, for connecting the punch-holder to eccentric F, as shown 5 more plainly in Figs. 3 and 5.

In the outside faces of the disks are radially or diametrically arranged grooves c for the insertion of a handle or crank, E to turn the disks E E and eccentric F for operating the punching-tool.

If desired, the pin or bolt connection g be tween the eccentric strap 9 and punch-holder D may pass through vertical slots (1, formed in the sides of guide a and be provided with end collars or nuts to serve as additional guides for the punch-holder.

To base-plate A is pivoted or fulerumed, as shown at a a vibrating arm or lever, H, having at its forward end a blade, 71, which is arranged to out against blade I) to make a shearcut. The opposite end of lever or arm H is slotted, as shown at h, and has an eccentric pin or connection, 71, with disk E, said pin.

working in a slot, h, in said lever end.

The operation is obvious. A movement of crank E, either by hand, a trcadle, or other power, rotates disks E E and eccentric F, which, through medium of strap g, actuates the punching-tool, and through the medium of eccentric-pin it, working in the slotted end of lever H, vibrates it to effect a shear-cut between the blades b. If desired, a steel or other plate, L, having circular or other shaped apertures, Z, is secured to the side of base plate A, adjacent to the lever H, which plate and lever are provided with correspondingly shaped apertures, Z, which are used for cutting off lengths of round or other shaped bars. This plate L and openings Z Z are placed near to the pivot-point a or in line with the body of the standard a, so as not to impair the strength of the base-plate and admit of it resisting the strain incident to cutting the bars into lengths. The combined shearing and punching device is secured to a suitable stand or platform, M, upon which is secured asuitable female die or analogous devices, on, for completing the punch part of the machine. I do not limit myself to any particular form of punching tool or die, nor to their arrangement, as the female die or hollow be inserted in the holder D.

To give sufficient strength to the punching end of the device, in order to enable it to resist the strains incident to the operation of punching, a standard or brace, N, is formed or cast thereon and suitably bolted to the platform M.

If desired, suitable threaded openings, 0, may be provided in grooves e to screw the handle E to either of disks E E, as shown more plainly in Figs. 2 and 4'.

In the cap edges a of disks E E, adjacent to the plates a are annular grooves a and these are provided to reduce the friction be tween said disks and plates. The grooves or slots 6 in disks E E may be arranged as desired; but I prefer to so arrange them that the slots of one disk are intermediate of the slots of the other disk, as shown more plainly in Fig. 1. This arrangement affords greater facility for changing the angle of the handle E", by removing it from the slot of one disk to that of the other disk to obtain better leverage.
