This invention relates to a device for holding the heel and the heel end of a shoe in proper relative positions while the shoe and the heel are being nailed on or otherwise secured together.

The device is particularly adapted for attaching wooden heels to womens shoes and is constructed and designed for use in shoe repair shops. To this end, the invention embodies certain novel features of construction whereby it is especially adapted for ready attachment to or removal from a work bench or a counter. In addition, the invention contemplates and provides novel means for clamping the heel and shoe in proper relative position without injuring or marring the heel or shoe.

Additional objects of the invention are topro- Vide a shoe clamp which is manually operated, simple and inexpensive in construction, and which is composed of few parts separably united and compactly arranged.

With the foregoing objects in view, the invention consists in the novel construction and ar rangement of parts hereinafter more fully described and pointed out with reference to the accompanying drawings, wherein:-

Figure 1 is a side view of the shoe clamping device in operative condition, the heel end of a shoe and the shop counter being indicated in dotted lines.

Fig. 2 is a top plan view of the device.

Fig. 3 is a front end View thereof.

Fig. 4 is a fragmentary side view partly sectioned to disclose the heel clamping members.

Fig. 5 is a horizontal section on line 5-5 of Fig. l.

Fig. 6 is a fragmentary detail View of the front heel clamping member, partly in section.

In order that the device may be conveniently attached to and supported on the corner of a bench or counter, such as indicated in dotted lines at 1, in Fig. 1, the various units are mounted on or made integral with a base plate 9 having laterally spaced lugs Ill and I9 depending from the under side thereof adjacent one end of the plate in overhanging abutting relation with one edge of the counter or other support; the plate being fastened to the support by screws, bolts or other fasteners, inserted through the holes I I in the plate. Integral with the plate and eX- tending vertically of the upper side thereof is a post having a T-shaped body portion I3 surmounted by a head I5 which is substantially square in cross section. The head l5 is grooved or recessed in its top side to provide spaced bearing lugs I1 and I1' which are apertured to receive the ends of the fulcrum or pivot bolt I9 at one end of an arm 2l, which is provided at its opposite or free end with a vertically disposed screw threaded bore in which is screwed a long clamping screw 23. The screw 23 is provided at its upper end with a handle 25 and at its lower end with a swivelled work-engaging member 21. Arm 2I extends forwardly of the broad face or head of post I3 with its free or screw bearing end overhanging the end of the base plate having the depending lugs I9 and I9'. By reason of its pivotal connection with post I5, the arm 2l is movable from a horizontal to a vertical position for substantially an arc of 90, and at its pivoted end is provided with a stop lug 29 adapted to abut the rear edge 3l of the post head I5 when the said arm is vertically disposed. Suitable means are provided for locking the arm 2l and clamping screw 23 in clamping position. The particular locking means illustrated comprises a plate 33 flexibly connected to the post by a string 35 and carrying a locking pin 36 insertable through aligned openings in the post bearing lugs I1 and I1; the arm 2l having an aperture adapted to register with the pin receiving openings in the post bearing lugs when the arm ZI is horizontally positioned as illustrated in Fig. 1. The T-shaped portion of the post serves as a vertical guide for the carrier 31 of the heel back clamping member 39. Carrier 31 comprises a tubular block having its rear end cut out, as at 4 l, to receive the broad head of the T-shaped post I3. A pair of angle straps 43 and 43', preferably of spring metal, are attached by screws 45 to the rear end of carrier 39 so as to engage rearwardly of the head of the post I3 and transversely of the rear flange thereof, as shown in Fig. 5; the said straps being secured at their outer ends by a ring bolt and nut assembly 41 whereby they may be clamped against the post I3 to hold the carrier 31 stationary on the post. The clamping member 39 carried bythe member 31 is preferably a wooden plug having its outer end concaved and arcuate to t snugly against and around the back portion o-f a shoe heel 49. Several different types of plugs 39 will be used separatelywith carrier 31 to accommodate different types of shoe heels, and the carrier is adjustable vertically of post I3 to enable the operator to set the plug or clamp 31 in exactly the right position against the back of the shoe heel as the particular design and journaled for rotation in lugs I9 and |0 of the base plate and having a crank arm 53 at one end. Shaft 5| is provided with a pair of through openings extending transversely therethrough and laterally spaced apart to be on the outsides of lugs I and l0', these openings being adapted to receive the legs of a U-shaped member or yoke 55 extending upwardly and around the front end of the base plate 9 so as to bear against the front portion of the shoe heel 49. Yoke 55 is adjustable relatively to shaft and is xed in any position to which it is adjusted by means of abinding screw 51 screwed into one end of shaft 5| and bearing against one leg of the yoke, as shown in Fig. 6. The means for rotating shaft 5| to .place yoke 55 into and out of heel clamping position, consists of a hand lever 59 pivoted at 6| to a lateral extension 63 of the base plate and having its lower end pivotally connected at 65 to one end of a link 61 which has its opposite end pivotally connected at 69 to the crankr53 of the shaft. Movement of the handle end of lever 59 to the left of Fig. l causes the clamping yoke 55 to be swung away from the back clamping member 39 or into heel releasing position. Reverse movement of the lever causes clamp yoke 55 to press the Vheel rmly against the back clamping member 39, the opposite end of which is in abutment with the broad face of the T-shaped post |3. Fastened to the base plate 9 by bottom lug and disposed concentrically with the axis of the lever 59, is a lever quadrant '|3 having an arcuate slot 'l5 through which extends the shank of a headed lbolt 'l1 carried by the lever 59 and having a wing nut 19 screwed on its inner end. When the wing nut is screwed up tight, the lever is clamped to the quadrant for preventing any movement of clamping member 55, and when the wing nut is loosened,`

the lever 59 may be swung freely within the limits 0f arcuate slot 75, for turning shaft 5| andswinging clamping member 55 into and outof clamping position.

In using the device, the wooden heel' 49 is placed on base plate 9 and clamped between

clamping members

55 and 39 by proper manipulation of lever 59. The shoe Yto which the wooden heel is to be attached is then positioned withthe heel end of the shoe resting upon the top of the wooden heel 49 as indicated in dotted lines in Fig. 1 and the arm 2| is then swung into position so that the clamping screw 23 depends inwardly of the shoe with the bearing plate 2! pressing the heel end of the latter against the heel. The screw 23 is then rotated by the handle 25 to clamp the heel end of the shoe and the wooden heel in proper relative position. In this conditionofjthe clamp, the first two nails are driven through. the bottom of the shoe and into the heel in front of the bearing end 21 of the clamping kscrew 23. The latter is then turned and the looking pin 36 pulled out to release the arm 27| which may be then swung upwardly and out of the way. The process `of attaching the heel and shoe is then nished by driving in the next three nails, there generally being ve nails in all in the heel of va womans shoe.

From the foregoing, it is Vthought that the operation and 'construction of the device will be readily understood.
