Application led .Tune 26, 1912. Serial No. 706,055.

To all whom 'it may concern Be it known that I, GEORGE E. MAXWELL,

a citizen of the United States, residing at Bronaugh, in the county of Vernon and State of Missouri, have invented new andA useful Improvements in Upsetting Attachments for Vises, of which the following is a specification.

This invention relates to devices for shrinking and upsetting tires and the like, and it has for its object to provide a simple, inexpensive and efficient upsetting device which may be readily applied to and used in connection with a blacksmiths vise of ordinary construction.

A further object of the invention is to provide a simple and inexpensive upsetting device which when not in use may be easily and quickly detached from the vise and stored in small compass.

vVith these and other ends in view which will readily appear as the nature of the invention is better understood, theV same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred form of .the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to when desired.

In the drawing,-Figure l is a perspective View showing the invention applied to an ordinary vise. Fig. 2 is a top plan view showing a portion of a tire applied in position to be operated upon. Fig. 3 is a side elevation illustrating a modified form of the invention, and also showing a portion of a tire in position to be operated upon. Fig. L is a top view of the same.

Corresponding parts in the vseveral figures are denoted by like characters of reference.

The improved upsetting attachment is composed of two members A and B adapted to be mounted, respectively, upon the movable jaw C and upon the stationary jaw D of an ordinary blacksmiths vise, said vise being equipped with a screw E for forcing the movable jaw in the direction of the stationary jaw. The jaws are forced apart in the customary manner by means of a spring F. The members A and B are each composed of a base plate 1, said base i plates being provided adjacent to their inner v or meeting edges with downwardV extending flanges 2 adapted to engage the faces of the vise jaws. Each of the base plates l is also provided adjacent to its outer edge with a downwardly extending flange 3 adapted to rest externally upon the vise which is usually provided with an enlargementor oifset 4 upon which the flange 3 may be supported. In the absence of such oiset, however, the flange 3 may be supported upon the body of the jaw.

Under the construction illustrated in Figs. 1 and 2 the base plates l are provided adjacent to one of their side edges with upwardly extending flanges 5 having teeth or corrugations, as shown at 6. Pivotally mounted upon each of the base plates l near the outer edge thereof is a cam lever 7 having a corrugated or toothed engaging face 8 and a handle 9 which extends a suitable distance beyond the edge of the base plate opposite to that having the flange 5 so as to be readily grasped by the operator standing in front of the vise or at one side of the latter.

In the operation of this device the members A and B are placed upon the jaws of the vise, while said jaws are separated or spaced apart, and the tire or article to be shrunk or upset is then placed upon the base plates l between the flanges 5 and the cam levers, the latter being actuated to grasp or secure the article between the corrugated faces of the flanges 5. The article may be steadied by the hand of the operator, while the screw E of the vise is actuated to force the movable jaw in the direction of the stationary jaw, thereby causing the article to be shrunk or upset, as will be readily understood.

Under the slightly modified construction illustrated in Figs. 3, l of the drawings the base plates here designated l of the members A and B are corrugated upon their upper faces, said base plates being provided adjacent to one of their side edges with upstanding flanges 5 upon which the cam levers, here designated by 7 are pivotally mounted. The handles 9 of said cam levers will thus extend upwardly instead of laterally from the vise, which may sometimes be found desirable. In other respects the construction and operation are precisely as hereinbefore described.

fis will be seen from the foregoing,` desci'iption, the improved upsetting attachment is extremely simple in construction and is capable o being pi'oduced at a very moderate expense. The said device may be very readily applied to any oidinaiy blacksmiths vise without the use of any special fastening` means, and it follows that the device may he applied o1l detached in a few moments. By this invention, the use of a special upsetting machine, the cost o which greatly exceeds that of my improved attachment, may he dispensed with.

Hating thus described the invention, what is claimed as new, is

lin upsetting device for vises including a noevee pair of base plates, one of the plates being adapted to he disposed upon each jaw of the vise, downwardly extended flanges projectingfrom the inner ends of the plates and adapted to engage the meeting,` faces of the vise, downwardly extended supporting)- legs projecting from the outer ends of said base plates and adapted to engage the sides of vise, and clamping levers for securing the work to the base plates.

ln testimony whereof l al'lnix my signature in presence of two witnesses.
