Claims.

This invention relates to devices for use in positioning work pieces relatively to each other and is illustrated herein with reference to the positioning on a shoe bottom of an outsole which 5 extends only a short distance rearwardly of the heel breast line of the shoe, the present application being a division of my copending application Serial No. 223, i69 filed September 6, 1938, and covering Methods for use in the manufacture of shoes.

Outsoles of the type referred to are frequently attached to shoe bottoms by pyroxylin cement in a sole attaching press, the cement being first applied to the outsole and the overlasted margins of the shoe upper and being then allowed to dry. Just before the sole attaching pressure is applied, the cement is activated by a solvent to put it in condition for sticking the outsole to the shoe bottom. Since outsol'es of the type referred to do not overlap the entire heel seat portion of the shoe bottom, it is especially diflicult, particularly in attaching presses having no sole and shoe positioning mechanism thereon, to position the sole and shoe relatively .to each other in the press after the solvent has been applied.

An important object of the present invention is to provide an improved device for use in relatively positioning objects such as shoes and soles and establishing such positions so that they may be readily reestablished prior to the permanent attachment of the sclesto the shoe bottoms.

To the accomplishment of this object the invention provides, in accordance with one feature, an improved article of manufacture comprising a resilient member in the form of a hinge similar to a pair of sugar tongs and having legs thereon which carry oppositely extending means such as prongs for securing the legs respectively to work pieces between which the hinge member is adapted to be located, said hinge member also having means at its rearward portion for further securing it to one of said work pieces.

As herein illustrated, one leg of the hinge member is provided with at least one prong adapted to secure it to a. work piece such as a shoe bottom, and it has another prong or prongs thereon spaced from the first prong also adapted to secure said leg to the shoe bottom, thereby establishing the leg and hinge member in position on the shoe bottom and maintaining said leg against movement relatively thereto. In accordance with another feature of the invention, the other leg of the hinge member is provided with means for securing that leg to another work piece, such as an outsole to be attached to the Divided and this application March 9,

shoe bottom, said means being constructed and arranged to maintain the outsole against movement in its own plane relatively to the shoe bottom or, in other words, against lateral movement relatively to the shoe bottom. Preferably, and. as illustrated, the last-named means may comprise a plurality of prongs spaced from each other and arranged to hold the outsole against said lateral movement.

With the above and other objects and features in view the invention will now be described in connection with the accompanying drawing and will thereafter be pointed out in the claims.

In the drawing,

Fig. 1 is a perspective view of the hinge member embodying the present invention; and

Fig. 2 is a perspective view of the hinge member being utilized in connection with the cement attachment of a short outso-le to a shoe bottom.

The device embodying the invention is indicated generally in Fig. 1 by the numeral 4 and comprises a hinge fastening member similar to a pair of sugar tongs and consisting of a pair of forwardly projecting legs 6 and 8 the forward ends of which are enlarged and provided respectively with a plurality of sets of prongs It] and [2 which are spaced from each other widthw-ise v of the legs and are arranged to be pressed or driven into a plurality of work pieces such, for example, as an outsole A (Fig. 2) and the bottom of a shoe B between which the hinge member is adapted to be mounted before the outsole is attached to the shoe bottom. As shown in Fig. 2, the outsole A is a so-called short outsole which extends only a short distance rearwardly of the heel breast line of the shoe.

The hinge fastening member 4 is preferably composed of thin, resilient material such as metal which is bent over upon itself to form [the legs of the hinge. Adjacent to its rearward end the hinge member is provided with another set of projections or prongs [4 whereby it may be readily secured to the heel seat portion of the shoe bottom, the prongs M, as shown, being punched or otherwise formed in the rearward end of the lower leg 8 of the hinge. Preferably and as illustrated, the prongs on the hinge member may be conveniently formed by stamping them out of the metal and turning them in the proper direction away from the legs of the hinge member. Moreover, the prongs of each set diverge slightly from each other to cause them to become bent or clinched in the material of the work pieces when they are driven into the same,

thereby securing the legs firmly to said work pieces.

In using the device the operator positions the hinge member 4 with the rear prongs i4 extending against the insole of the shoe B at its heel seat portion, the insole being designated by .the numeral 16. The overlasted marginal portions of the shoe upper will at this time have been coated with cement l8 such, for example, as pyroxylin as shown in Fig. 2, and the marginal portion of the attaching surface of the outsole will likewise have been coated with cement 20 which has been allowed to dry in the usual manner. After the operator has positioned the hinge member so that the legs 6 and 8 extend forwardly in overlapping relation to a metal shank piece 22 in the shoe bottom, as shown in Fig. 2, he presses or drives the rear prongs l4 into the insole, thereby securing the hinge to the shoe bottom. While this operation can, if desired, be performed manually with a suitable tool or driver, it may be conveniently performed with the aid of the machine disclosed in a copending application Serial No. 327,881, filed April 4, 1940, in my name. It will be observed in Fig. 2 that the forward prongs I2 on the lower leg 8 of the hinge member are spaced far enough apart so that they will not engage the shank piece 22 but will preferably be located in positions to engage the inner portions of the overlasted margin of the upper.

After the hinge member has been secured to the insole I6, as described above, the outsole A may be placed on the shoe bottom with the rear portion thereof overlying the forward ends of the legs 6 and 8 of the hinge member, The operator may then position the outsole properly with respect to the shoe bottom and press or drive the diverging sets of prongs I0 and I2 on the opposite legs 6 and 8 into the outsole and shoe bottom, respectively, thereby securing and maintaining the hinge member 4 against movement relatively to the shoe bottom and also establishing the relative positions of the outsole and shoe laterally and longitudinally while the sole and shoe are located in their proper relative positions. While the above operations may be carried out by hand, a convenient way of performing them is with the aid of the machine disclosed in my copending application hereinbefore referred to.

The operator may now raise the outsole away from the shoe bottom, as shown in Fig, 2, and, by a brush 24 or other suitable implement, apply a solvent to the cement on the attaching surface of the outsole and, if desired, to that on the overlasted margin of the shoe upper. As illustrated in Fig. 2, this operation may be readily accomplished with the aid of the hinge member 4 without losing the previously established positions of the sole and shoe relatively to each other. After the solvent has been applied the outsole A may be returned to its former position on the shoe bottom and the members mounted in a cement sole attaching press to attach the outsole permanently to the shoe bottom. In placing the outsole and shoe in the attaching press, the operator can conveniently assist in maintaining the forepart of the outsole in a proper position laterally of the shoe bottom by hand if that appears to be necessary.

The hinge member 4 will, of course, remain permanently'in the shoe bottom but, since the diverging sets of prongs ii), [2 and M are not long enough to extend completely through the outsole or insole but become clinched in the material thereof, the presence of the hinge member is no detriment to the finished shoe. While the hinge member 4 has been described herein in connection with the cement attachment of short outsoles to shoe bottoms, it should be understood that this member is not limited in its application or utility to such outsoles nor to the cement attachment of outsoles to shoe bottoms as distinguished from their attachment by other means.
