Application November 20, 1936, Serial No. 111,931 6 Claims. (C1. 12-125) This invention relates to a device for holding the heel and the heel end of a shoe in proper rela tive positions while the shoe and the heel are be ing nailed on or otherwise secured together. The device is particularly adapted for attach ing wooden heels to women’s shoes and is con structed and designed for use in shoe repair shops. To this end, the invention embodies certain novel features of construction whereby it is especially 10 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 15 shoe. Additional objects of the invention are to- pro Vide a shoe clamp which is manually operated, simple and inexpensive in construction, and which is composed of few parts separably united 20 and compactly arranged. With the foregoing objects in view, the inven tion consists in the novel construction and arrangement of parts hereinafter more fully de scribed and pointed out with reference to the 25 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 sec tioned 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 40 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 sur mounted 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 bear~ 55 ing 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 oppo site or free end with a vertically disposed screw threaded bore in which is screwed a long clamp ing screw 23. The screw 23 is provided at its Ci 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 over hanging 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 clamp ing screw 23 in clamping position. The particu lar 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 30 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 car rier 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 sta 40 tionary on the post. The clamping member 39 carried bythe member 31 is preferably a wooden plug having its outer end concaved and arcuate to ñt snugly against and around the back por tion o-f a shoe heel 49. Several different types 45 of plugs 39 will be used separately’with 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 50 of the shoe heel as the particular design and shape of the heel may require. In advance of the back clamping member 39 and cooperably positioned relative thereto is a front clamping assembly comprising a shaft 5I 2 ' ` 2,124,144 journaled for rotation in lugs I9 and |0’ of the ings extending transversely therethrough and lat post, a heel front clamping member on said plate and movable to and from proximity with the bask heel clamping member, and a shoe clamping member mounted on said post and adjustable to erally spaced apart to be on the outsides of lugs I0 and l0', these openings being adapted to re a position for clamping the heel end of a shoe 5 against a heel clamped between the said front and ceive the legs of a U-shaped member or yoke 55 back heel clamping members. base plate and having a crank arm 53 at one end. Shaft 5| is provided with a pair of through open extending upwardly and around the front end of 2. A shoe clamp comprising a base plate, a the base plate 9 so as to bear against the front perpendicular guide post thereon, a slide on said portion of the shoe heel 49. Yoke 55 is adjustable .Spost, a removable member in said slide and ex relatively to shaft 5| and is ñxed in any position tending horizontally outwardly therefrom in par to which it is adjusted by means of abinding allelism with the base plate with its outer end screw 51 screwed into one end of shaft 5| and shaped to receive and to support the back portion bearing against one leg of the yoke, as shown in of a shoe heel, a member pivotally mounted on Fig. 6. The means for rotating shaft 5| to .place said plate for engaging the front portion of a yoke 55 into and out of heel clamping position, shoe heel to clamp the latter against the member consists of a hand lever 59 pivoted at 6| to a lat supporting the back of the heel, and an arm eral extension 63 of the base plate and having its pivotally mounted in said post for adjustment to ward and away from the heel clamping members, 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 ñrm ly against the back clamping member »39, the op posite 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 con centrically 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 car ried 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 and a clamping screw at the free end of said arm 20 for clamping the heel end of a shoe upon the shoe heel. 3. A shoe heel clamping device comprising a base plate, a pair of heel clamping members mounted on said plate, one of said clamping members being mounted to turn about a ñxed axis and the other member being mounted for adjustment vertically of the plate to accommodate heels of varying heighths, 'a clamping screw adapted for insertion in the heel end of a shoe for clamping same against the top portion of a shoe heel, clamped between the heel clamping members, means carrying said clamping screw and adjustably connected with said plate for moving said clamping screw into and out of shoe clamping position, and individual means asso quadrant for preventing any movement of clamp ciatedwith the clamping units for locln'ng them ing member 55, and when the wing nut is loosened,` in clamping position. the lever 59 may be swung freely within the limits 0f arcuate slot 75, for turning shaft 5| and‘ïswing ing 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 manipula tion of lever 59. The shoe Yto which the wooden heel is to be attached is then positioned with‘the 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 pro per 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 ïway. ’ The process `of attaching the heel and shoe is then ñnished by driving in the next three nails, there generally being ñve nails in all in the heel of va »woman’s shoe. From the foregoing, it is Vthought that the op eration and 'construction of the device will be readily understood. ` What is claimed as new isz 1.
