Our invention relates to adjustable heel clamps, especially useful in holding high heels during the process of attaching to shoes, and itconsists in the constructions, arrangements and combinations of parts herein described and claimed. Y

It is an object of our invention to provide a clamp which is readily'adjusted to accommodate heels of various sizes'and shapes.

A still further object of the invention is to provide clamping jaws of such formation as to hold the heel in'rigid position,.while yet preventing themarring or splitting of the heel during the nailing operation of the heel to the shoe.

Additional objects, advantages, and features of invention will be apparent from the following description considered in conjunction with the accompanying drawings forming a part of this application, wherein;

Figure 1 is a perspective view of our clamp;

Figure 2 is a and Figure 3 is a cross section on the line 3-3 of Figure 2.

In carrying out our invention we provide a support 1 having lateral ears 2, suitably apertured for fastening means. The support 1 may, however, be providedwith a central angular recess 3, to accommodate the clamp to the usual repairmans jack.

Upon the support there is integrally formed a head 4, which comprises a clamping jaw and ear ,6. The head 4 together with its associated jaw 5' and ear 6 thus presents a figure substantially U- haped in cross i'ection. The upper surface of the head 4: is planiforin and extending longitudinally thereof we provide a rib 7. The rib 7 stops short of the jaw 5 a suitable distance, and closely adjacent the jaw 5 there is an adjusting screw 8. The screw 8 extends vertically and is screw threaded through the head 4 and extends in a plane parallel to thejaw 5. The screw has a supporting head 9 and oper ating knob 10, whereby the supporting headmay be raised or lowered, as'desired.

The jaw 5 is enlarged at its upper part and curved to overlie the head l-slightly.

longitudinal section thereof;

The enlarged part is suitably rabbeted to receive a'resilient pad member 11, this pad preferably being formed ofrubber, andof oblong shape, in order to accommodate heels of various sizes, as will be apparent, as the description proceeds. j j p A longitudinally movable jaw 12 is slidably mounted upon the rib 7. The jaw 12, in the present instance, is substantially V- shaped in top plan, having a smooth lower edge 13, adapted to slide upon the upper surface of the 'heade. Upon the rear portion of the jaw 12, there isprovided a recess 14 having a rear wall15. The wall 15 is cut away, as at 16, to permit sliding engagement with the rib 7 It should be noted that the rear portion of the jaw 12 is inclined and presents a jaw of tapered formation extending inthe direction of the fixed jaw 5. By

thisconstruction, heel's'of var'iouslongitudi- To 7 nalv configurations may be readily gripped between the opposed jaws 5 and'12. v I

The ear 6 is suitably apertured' and threaded,intermediate its height, to receive an operating stud 17. The stud 17 com- 7 prises a head 18 upon one end, the opposite end being reduced, as at 19 and has-a head 20. The head and the reduced portion 19 are split lonigtudinally as at 21, so that these parts may be compressed for insertion so in the aperture 19a of the rearwall 15. As soon as the head 20 has passed through the wall, the head will spring outwardly dis} posingshoulders beyond the aperture we; thus preventing withdrawal of the stud 17. The interior portion of the j aw 12 is preferably provided with a suitable facing 21, which may be sponge. rubber, felt or the like, or any other material which will afford the necessary protection to an engaged heel, It should also be noted that the recess 14 permits the facing 21 to flex or swing thereinto, thus 'ac' commodating heels of variousconfigurations, yet affording ample support throughout the length thereof. v

In the use of our device, a selected heel A I is positioned with its ground engaging portion resting upon the support 9 and its fiat face B abutting the padll. The heel A may be raised or lowered to position the heel ai suitable distance above the jaw 5, by manipulation of the screw 8. The operation stud 17 is now rotated to move the jaw 12 into engagement with the rear portion of the heel A. Any degree of pressure may be exerted upon the heel to securely hold it, and due to the pad 11 and the facing 21, all possibility of damaging the heel is obviated. With the heel thus supported the shoe may be readily nailed to the heel.

From the foregoing it will be seen that I have provided a clamp of simple construction, yet efficient in operation, and one, by virtue of its V-shaped clampingj aw, will accommodate heels of various shapes and sizes.

l/Ve claim:

1. A work holder comprising a frame hav ing a fixed jaw, provided with a resilient gripping member in its upper portion, a longitudinally movable jaw carried by said frame, said movable jaw comprising a substantially V-shaped gripping member, said \/shaped member having a tapered portion extending from its upper edge inwardly toward the fixed jaw to accommodate work of various configuration, a flexible lining carried by said movable jaw suspended from its upper portion, the lower parts of said jaws being offset from their upper portions, whereby the work is held by the upper portions of said gripping members.

2; A clamp for the heel of a shoe, comprising a fixed jaw, a movable and means for moving said movable jaw, said movable jaw beingof V shaped formation with a recess therein and provided with a flexible lining mounted for swinging movement in said recess.

3. A worx clamp jaw, comprising a rigid wall, having a projecting portion and a rece d,- ing portion, and a flexible wall, mounted on said projecting portion for swinging movement insaid receding portion.

4:. In awork clamp jaw, means forengaging; the work, consisting of a rigid wall, having a projecting and a cutaway portion, and a flexible wall mounted on said projecting portion, and swinging in said cut-away portion.

5. A. work clamp jaw having a rigid wall, a. flexible wall supported on said rigid wall for engagement withthe work, and means for positively limiting the flexing movement of a: portion of said flexible-wall;

6. A work clamp jaw having a recess, a flexible Wall movable into said recess upon engagement with the. work, and means for rigidly supporting, a portion of said flexible wall.
