ELAM A. OLIVER, OF BELLEVILLE, WISCONSIN.

COMPOUND METAL-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 322,847, dated July 21, 1885.

a Application filed June 24, 1884. (Munich) To all whom it may concern.-

Be it known that I, ELAM A. OLIVER, of Belleville, county of Dane,and State of Wisconsin, have invented a new and useful Improvement in Vises and Shears; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it ap-, pertains to make and use it, reference being had to the accompanying drawings forming a part thereof.

This invention is an improvement in combined metal-working machines; and it has for an object to provide a single machine, which may serve the purpose of a vise, punch, shears,

bolt-header, or tire-shrinker, all of which will be described,. and then pointed out in the claims.

In the drawings, Figure 1 is aside elevation of my machine. Fig. 2 is a detail view of the bolt-heading attachment. Fig. 3 is a detail view of the tire -shrinking attachment;Fig.

4, a detail view of the attachment for shaping horseshoe-calks, and Figs. 5 and 6 are detail perspective views of the upper part of the machine.

In Figs. 5 and 6 the bar 12 is shown lower down on the standard than in Fig. 1; but it is the same bar-in general construction and function.'

The standard or upright D may be provided with feet 10, which in practice are secured to the floor or on a suitable base. Near its upper end the standard is provided with forwardlyproj ected parallel arms a, between the ends of which the movable bar 0 of the machine is pivoted at (4 I prefer to provide these arms by bending a flat bar of metal centrally between its ends and securing it by welding or otherwise to the standard D, as will be understood. This construction serves to strengthen the standard and prevent any cracking or splitting thereof.

The upper ends of both bars 0 and D are provided at their inner edges with shoulders 7, which serve as support-s for any object which it is desired to clamp between the bars 0 D, as in a vise. These shoulders also serve as offsets on which to rest the inner sides of the sockets, presently described, so that the inner faces of such sockets will lie flush with or within the inner edges of the bars 0 D. The blade 8 is secured to the movable arm 0, and has its cutting-edge suitably beveled and ar-- ranged to out against the opposite edge of the standard, in which it is usual to seat a steel plate or blade to provide a durable cuttingedge. As the arm 0 is turned on its pivot a the blade 8 cooperates with the blade on the arm D, shearing any interposed metal.

In order to support the metal being cut, I provide the gage-plate 13, which is slotted at a, and has its lower edge bent under the arm a of the standard. This gage-plate is arranged on the opposite side of the machine from the blade 8, and is secured by a clampingscrew, a, turned through slot a The lower bent edge of the gage-plate suffices to hold such plate from turning on the screw a, and such screw operates to secure the said plate at any suit-able point of adjustment. The purpose of this plate is to support the bar being sheared so that the cut of the same may be right-angled or at any other angle desired.

In operation the bar is placed between parts O D, and bears at one side against standard O and at its other side against the gageplate 13, which may be set up or back'in order that the bar may be clamped at any desired angle. This gage-plate alscprevents any twisting of the bar while being sheared.

The bar 12 is arranged on the outer side of the arm 0, and is provided with arms b. I by preference form the connection between the standard D and the bar 12 by bolting the latter to the arms a of the standard, as shown. This bar 12 has an opening, I), and is provided with guides b", in which the die b of the punch may be removably held, so that it may be detached and another substituted in its stead for the purpose of punching larger or smaller holes.

The punch 15 is removably held by a setscrew to a supporting-bar, 14, which has a band, 16, encircling the bar 0, or may be otherwise secured thereto, as desired.

The operation will be easily understood. The die being on the fixed and the punch on the movable arm as' the latter is operated the interposed object will be punched as desired; To secure the metal against the die I provide a keeper-plate, B, which is fixed to the outer face of bar 12, below opening b, and extends thence upward above the said opening, and is arranged a sufficient distance away from the support 12 to receive and hold the bar being punched. This plate is formed with a slot, through which the punch 15 operates.

The arm 0 is provided near its lower end with a slot, 5. The foot-lever B is pivoted at 2 to the standard, and is provided at one end with a pin or roller, which operates in the slot 5, and at the other end withtreadle a. As the treadle is depressed the arm 0 is so operated as to cause its upper end to approach that of the bar D. The pivot-pin 2 of lever B extends through said lever, the standard, and an arch-plate, 9, arranged parallel thereto.

To return the treadle to place I provide a spring, 3, coiled on pin 2, and having one end attached at 4 to the opposite end of the lever, and its other end fixed to the standard or the plate 9, as desired. The treadle a of the lever B may be fixed rigidly or be pivoted thereto at B, and provided with a stop-lug, 1, bearing under the lever in advance of such pivot, so that the treadle will be rigidly connected with the lever B as to downward pressure, but will yield freely upward, so that it may be folded over against the standard and out of the way when the machine is not in use. A braceplate, 11, extends from the standard D alongside the bar 0, and serves to guide and steady the movements of said bar.

Each of the attachments E, F, and G have sockets 17. which are simply blocks mortised or recessed in their under sides to fit on the upper ends of arms 0 and D.

The bolt-heading construction shown in Fig. 2 has been claimed by me in a separate application, filed March 26, 1884.

The tire-shrinker F, (shown in Fig. 3,) consists of serrated base-plates f, provided with overhanging frames f, in which are journaled the toothed clamping-rollers 18, provided with levers 19.

In operation the j aws of arms 0 D are opened,

the parts F placed thereon, and the tire placed on the plates f. The rollers 18 are then clamped on the tire, and the jaws closed, effecting a shrinking of the tire by condensing that portion between the rollers 18.

The construction G (shown in Fig. 4) is for shaping horseshoe calks. In operation the attachment is applied to the arms 0 D, and the shoe is placed and held between the jaws of the arms 0 D. The toe calk can then be hammered out on the smooth beveled face of the attachment, and the heel-calks may be bent over and shaped in the grooves of the other section. The toe-calks can also be put on the shoe hot and welded on in the grooves of the attachment G. 7

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination of the standard, the arm Opivoted thereto and provided with a cuttingblade, and a gage-plate 13, supported by the standard and adjustable, substantially as and for the purposes specified.

2. The combination of the standard, the bar 0 pivoted thereto, the bar 12 arranged on the outer side of the bar. 0, and supported on the standard, the die carried by the bar 12, the bar 14:, and the punch supported thereon, substantially as set forth.

3. The combination, with the standard and the bar 0, both provided on their inner edges near their upper ends with shoulders 7, of the attachment bearing-sockets 17, adapted to fit on the standard and bar (3. and rest ,on shoulders 7, with their inner faces flush with the inner faces of the standard and the bar 0, substantially as set forth.

In testimony that I claim the foregoing, I append my signature.

ELAM A. OLIVER.
