In. the pastithas, been the practice of shoe,- l makers or cobblers to hold a shoe on a last by of a strap or sling passing over the shoe and looped d to receive the cobblers foot. This requires that the cobbler always have a foot in the. sling while working on a shoe, which pre- 30, vents freedom of movement and is generally a clumsy method. of. holding the shoe. With our improved vise th c bble s not v to keep his foot in a strap.

In terms of broad inclusion, the shoe vise embodying our invention is mounted on a shoe last supporting stand. The vise comprises means for holding a shoe on the last, and means for fastening the in shoe holding position. The shoe holder is preferably a pivotally mounted arm having a strap for engaging the shoe, so that when the arm. fastened down the strap is tightened against the shoe.

In greater detail, and referring to Figures 1 and 2 of the drawing, our shoe vise is mounted on the ordinary stand 2 which supports a shoemakers last 3. The vise comprises a bracket 4 having a sleeve portion 5 embracing the stand. The mounting sleeve has a hinged section and the parts are clamped about the stand by any suitable means, such as a hinged bolt and lever nut 5. The bracket extends upwardly and rearwardly and terminates in a forked portion 7.

A shoe holding arm 3 is pivotally mounted on the bracket on a pin 9 between the legs of fork I. This arm is yokeshaped, and in the shoe holding position shown in- Figure. 1, fingers lilrof the yoke project forwardly about the sides. of a shoe H- on the last. The yoke. fingers. have. slots t2: for carrying a strap. l3 extending across. the

.wardiy. below the shoe. sole, so that the upper surface of the shoe is left substantially clear for working purposes. Strap it of" course extends across the top, butthatis. also. true at straps prov is movable from itsv shoe viously used. Arm 81 holding positionlto a retracted position extending rearwa-rdlyl, as. shown by. dotted lines; in Figure i. In this. retracted: position the arm is out; or the way, and the shoe is free forren'ioval from the last.

Means are: also provided for urging arm 8- into retracted position, so. that as soon as the arm.

is released it swings back out of the way For this purpose. a spring lz i ispreierablycoiled; about the pin with one end anchored in the fixed; pin and the other and fastened to. the arm. end it. or the arm is. preferably bifurcated as shown in Figure 2, to. give a wider bearingtoallow a central placing of spring M. fiuitable stops or lugs H: on the arm and bracket serve to limit the in retracted position.

Means are provided for clamping arm 8 down in shoe holding position to tighten strap l3 against the shoe. For this purpose a hooked-shaped cam i8 is pivotally mounted by a pin is extending between fork l of the bracket, and is adapted to engage a pin 2! extending between the sides of bifurcated arm portion 16. Face 22 of the cam is designed to apply downward pressure on arm 8 when the cam rotates ahead; and the hook of the cam extends forwardly so that the cam rides off pin 2! to free the arm when the cam rotates backwardly.

Means are provided for actuating the cam. As

best shown in Figure l, a lever 23 is also fixed on pin 19 and extends forwardly to provide an operating handle or knob M conveniently arranged below the last. The lever is movable between clamping and release positions; the latter being indicated by dot and dash lines in. Figure 1. .An unbalanced spring 26 is connected between the bracket and lever and serves to urge the lever.

into one or the other of its positions as the spring passes over the pivot center; Stops or lugs 21 on the lever and bracket serve to limit movement of the lever; and the upper limit is set so that pin 2| clears the end of cam l8 to allow arm 8 to.

be brought down.

In the operation of the vise, arm 8 is first brought down and lever M is then pushed down to engage cam lt-with pin 25. Once engaged, arm 8 is automatically held, and further downward movement of the lever tightens strap it against the shoe by reason of thecam action. After the strap has been tightened, arm 8 stays in the clamped position because of the friction between cam l8 and pin 21, and also because of the tension in spring 26 tending to hold lever 23 down. Cam surface 22 need not be steep, since a small movement here results in a large movement at the end of the arm. Thus there is little tendency of arm pin 2! to move back out on the cam.

When it is desired to free the shoe it is only necessary to tln ow lever 23 into its up position, thus releasing arm 83 and allowing the latter to swing back into its retracted position. With 8 out of the way, the shoe may be worked on Without being clamped down, or the shoe may be removed.

While we have shown the pivot mounting of arm 8 at the heel side of the last, it is understood that the Whole arrangement may be reversed to position the bracket under the toe.

Figures 3 and l show a modified construction comprising a strap 3! connected to a yokedshaped arm having fingers 32, one of which extends into a lever 33 terminating in a handle arm in a selected position. For this purpose a disc or segment 39 is formed on the bracket and is provided with notches for receiving a springpressed dog ii actuated by a button 42 at the end of the handle.

By this simple arrangement the lever may be pressed down and locked when sufficient tension has been put in the strap.

When the stand is turned around for the cobbler to Work from the heel end of the shoe, the

- yoke arm is thrown over to the opposite side,

as indicated by dotted lines in Figure 3, to tension the strap from the opposite angle. The action of the hold down strap is thus substantially the same as the slings now used, except that the foot of the cobbler is left free.

The yoke-shaped shoe holding arm is so pivoted that the strap pulls down at substantially the same angle for either side of the stand; and the yoke finger length'is such that the strap automatically clears the shoe when the arm is thrown over. When the device is not in use the arm and strap hangdown in retracted position alongside the stand where they are completely out of the Way.

We claim:

1. The combination with a shoe last and supporting stand, of a shoe vise comprising an arm 2. The combination with a shoe last and supporting stand, of a shoe vise comprising an arm pivotally mounted for movement between operative positions extending from opposite sides of the. stand, a strap on the arm for engaging a shoe on the last in either position of said arm, and means for holding the arm in either of its oppositely extending positions.

3. The combination with a shoe last, of a shoe vise comprising a strap for straddling the instep of a shoe on the last, the depending ends of the strap slanting forwardly in one position to draw the heel of the shoe against the last and slanting rearwardly in another position to draw the toe of the shoe against the last, and means for tensioning the strap in said positions.

4. The combination with a shoe last, of a shoe vise comprising a strap for straddling the instep of a shoe on the last, the depending ends of the strap slanting forwardly in one position to draw the'heel of the shoe against the last and slanting rearwardly in another position to draw the toe of the shoe against the last, and means including an arm pivoted about an axis lying below said instep and movable from one side to anotherof said axis for tensioning the strap in its forwardly and rearwardly slanting positions.
