6 Claims.

The invention relates to improvements in shoe sole laying and lasting machines and has for its primary object the provision of an improved machine or appliance of the character indicated which is capable of economical production and highly eiiicient in use.

Another object of the invention is the provision of a construction of the character indicated so constructed and arranged as to facilitate the proper shaping of a shoe and fitting of the sole thereto. v

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification and in which- Fig. 1 is a top plan View of the clamping arrangement employed in the device;

Fig. 2 a side View of the complete device on a reduced scale;

Fig. 3 a partial section taken substantially on line 3 3 of Fig. l; and

Fig. 4 a section taken substantially on line 4 4 of Fig. 1.

The embodiment of the invention illustrated in the drawings comprises a suitable supporting frame li; generally in the form of a. table. A vertical last spindle II is arranged as shown at the topV oi said table adjacent the front end thereof. The shoe last of usual construction and carrying a pre-welt shoe I2 is provided with the usual socket to receive the upper end of the spindle I i as will be readily understood.

Two laterally swinging plates or wipers I3 are arranged as shown on opposite sides of the shoe and last, each clamping plate being provided with curved beveled edges I4 nicely shaped as best shown in Fig. 1 to the contour of the corresponding sides of the rear portion of the pre-welt shoe on the last. At the inner ends the clamping plates I3 are reinforced at top and bottom by reinforcing plates l5 and carry trunnions I3 fitting into sockets in the tops of supporting posts Il and whereby the clamping plates .I3 are pivoted to swing toward and away from the last in planes just below the welt of the pre- 50?, welt shoe on the last.

ly over` the tops of the posts I8 and are provided with stop blocks i8 which limit their inward swing at the proper positions. At their forward ends the clamping plates I3 are provided with handle members I9 arranged to be secured Q- The plates I3 pass free' gether in their innermost portions by a latch member 20 as best shown in Fig. v1.

A third clamping member 2l is arranged as shown to slide in guide grooves 23 formed in the sides of the supporting frame and also to enter guide grooves 23 formed as best shown in Fig. 4 between the inner edges of the reinforcing plates which are extended for this purpose, said third clamping member thus being caused to operate in the same plane as the clamping plates i 3. The third clamping member 2I has its inner edge 24 beveled and shaped to the contour of the toe portion of the prewelt shoe on the last, as will be readily Aunderstood. The clamping plate 2I is normally held in retracted position by means of a tension spring 25 and is connected as shown with the ends of a pair of operating wires 26 attached to posts El on the underside thereof. Operating wires 25 lead thence forwardly and downwardly around the guide member 28 where they are connected with the upper end of a belt or strap 29 in turn connected with the foot lever 3D for operating the same.

In use and in operation a pre-welt shoe comprising the usual upper, insole and welt are secured to the last by temporary nails in the usual Way and said last is then placed on the spindle II and nicely adjusted thereon until the plane of the clamping plates 2| and I 3 is arranged to pass just under the Welt of the shoe. The edges of the plates I3 are then fitted around the shoe just under the welt, and tightened and secured in place about the rear portion of the shoe to shape and hold the corresponding portions thereu of on the last, as will be readily understood. Then the foot lever 3B is operated to draw the clamping member 2| into position to similarly clamp about the shoe to shape and hold the toe portion thereof in place on the last. As will be noted, the clamping plates I3 are pivoted to swing on the trunnions I5 which are located opposite the toe portions of the last so that when clamping plates I3 are swung inwardly they first engage and position the sides of the upper before the heel portions are effectively engaged thus facilitating the stretching and shaping of the upper to the last. Then the nails securing the insole in place are withdrawn, adhesive is apu plied to the insole and welt and the outer shoe sole applied by heavy pressure and pounding to be accurately and nicely secured in place. When this has been done the shoe is in condition for removal and sewing and trimming of the insole.

By this arrangement the shoe soles may be spirit of the invention. I, therefore, do not wish to be limited to the precise details of the construction set forth, but desire to avail myself of such variations and modifications as fall within the scope of the appended claims.

I claim:

1. A device of the class described comprising av pair of opposed clamping members pivoted to swing toward and away from the rear sides and rear of a last positioned between them, said members being pivoted to swing at points opposite the toe portions of the last and in planes located substantially below the welt of a shoe member on said last and shaped to fit the cor- Iresponding shoe sides; means for forcing said clamping members. toward each other to clamp and shape a shoe upper to said last; means for locking said clamping members in clamping positions; a third clamping member arranged and mounted for movements toward and away from the toe portion of said last in a plane located substantially below the welt of a shoe on said last and shaped to fit the toe portion of the shoe; and means for operating said third clamping member.

2. A device of the class described comprising a. pair of opposed clamping members pivoted to swing toward and away from the rear sides and rear of a last positioned between them, said members being pivoted to swing at points opposite the toe portions of the last, and in planes located substantially below the welt of a. shoe member on said last and shaped to flt the corresponding shoe sides; means for forcing said clamping members toward each other to clamp and shape a shoe upper to said last; means for locking said clampingl members in clamping positions; a third clamping member mounted to slide toward and away from the toe portion of said last in a plane located substantially below the welt of a shoe on said last and shaped to fit the toe portion of the shoe; and means for operating said third clamping member.

3. A device of the class described comprising a pair of opposed clamping members pivoted to swing toward and away from the rear sides and rear of a last positioned between them, said members being pivoted to swing at points opposite the toe portions of the last and in planes` located substantially below the welt of a shoe member on said last and shaped to flt the corresponding shoe sides; means for. forcing said clamping members toward each other to clamp and shape a shoe upper' to said last; means for locking said clamping members in clampingy positions; a vthird clamping member arranged and mounted for movements toward and away from the toe portion of said last in a plane located substantially below the welt of afshoe on said last and shaped to fit the toe portion of the shoe;

a spring normally holding said third clamping member in retracted position; and means for forcing said third clamping member toward said last.
