It is the general object of our invention to provide a new construction of shoe. or slipper, in which the upper, insole and out-sole are secured together in a new and improved manner.

A further object is to provide an improved method of making the shoe and assembling and securing the parts thereof together, by the use of which method marked economy of manufacture is attained. The shoe or slipper thus constructed is of attractive appearance and possesses excellent wearing qualities.

Our invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

Preferred forms of the invention are shown in the drawings, in which Fig. 1 is a side elevation of a special last used in carrying out our invention;

Referring to the'drawings, our improved method of making a shoe or slipper involves the use of a 15 special or preliminary last L, shown in detail in Figs. 1, 2, 3 and 24. v

This special last L comprises an upper part or body portion 25 of standard shape and commonly made of hard wood. A metal plate 23 is perma- 20 nently secured to the bottom of the last and extends beyond the edges of the last, thus providing a flange portion or projection 21. This flange may extend entirely around the last as shown at 21. in Fig. 24 or may be confined to the front and shank portion as indicated at 21 in Fig. 3. This metal plate 26 or 28' is provided with the usual openings 23 through which the insole member may be tacked to the last.

In making a shoe by our improved method. we first take an oversize insole 30 (Fig. 4) of any suitable material, such as fibre board. This material should be relatively thin but of substan-.* tial stiffness. Before assembling the insole 33 on the last L or L, we apply a coating of a suitable cement around the edge of the insole on the bottom face thereof, as-indicated at 3| in Fig. 4.

We then secure the insole 30 to the bottom of the last by tacks 32 (Figs. 5 and 7) it being essential that the insole shall be of the exact outline of the metal plate 23 and that the edge of the insole shall coincide with the edge of the plate.

We next assemble the upper 33 on the last L, bringing the edge portion 34 of. the upper around the edge of the last plate 26 and insole 33, and pressingit firmly against the cemented portion 3| of the bottom of the insole. -Preferably the edge portion of the upper is given a cement coating before the parts are assembled.

We then remove the tacks 32 and draw the special last L out of the partially assembled shoe, leaving the upper 33 and insole 30 in the assembled relation shown in Fig. 8.

We then insert a row of stitching 36 (Figs. 9 55 and 10) around the edge of the insole and up-' per, thus binding the doubled edge portion of the upper 33 around the edge portion of the insole 30 and securing it at both faces of said insole.
