VICTOR rEssEmER} or 'rncomeQwAsnmeron,

This invention relates] to V a method of manufacturing shoes, designed primarily for use in connection with the well known type' of McKay stitching machines, butit is to be understood that a method, in accordance with-this invention, can be employed in connection with any form of shoe stitching ma I referred 'to whereby the: rear portion of the inner sole, outer sole and upper and the forward portion of the outer sole and upper are stitched together from within the interior of an upper after ,being lasted and with the last removed, and further with the fore part or portion of the upper maintained in extended, lasted or shaped position during the stitching of the fore outer sole together,

Further objects of the invention are to provide, in a manner as hereinafter set forth,

a" method for manufacturing shoes and which eliminates the fore part of the inner sole of the shoe, thereby givingthe shoe the flexibility of, a hand, turn at the front and the stamina, rigidity and high arch support at the rear, as is obtainable more particular ly inthe McKay method orprocess of manufacturing shoes.

A further object'of the invention is to provide, in a manner as hereinafter set forth, a method of manufacturing shoes which provides for a shoe with an unusually satisfactory smooth inside soleon which the foot rests, eliminates tacks which are employed in the McKay process or method, and further eliminates heavy rough seams inside of the completed shoes which are present in the hand turned production of shoes.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a method of manufacturing shoes which .is

simple in its use, thoroughly efficient, conveniently carried out, and comparatively inexpensive to employ.

With the foregoing and other objects inv view, the invention consists of the novel combination and arrangement of steps hereinafter more specifically described in carrying out the method, but it is to be understood that changes, variations and modifications with respect to the steps of the method can be resorted to which fall within the scope of the claim hereunto appended.

a Figure 4 is asection on line Figure 3. Figure 5 is a transverse sectional view of the completed fore part of the shoe; Figure'ti is a section on line 66Figure 3. Referringtolthe drawings-in detail 1 denotesa lastprefe'rably of the ordinary Mc- Kay type and which has connected to the fore part or front portion thereof a shell'2 .of rigidimaterial; The shell 2 conforms to further is inturned throughout its bottom to form a gripping flange 3 of appropriate width. The material from which the shell 2 is constructed is of the desired thickness. The shell 2 completely encloses the top, sides and toe portion of the last lat the front portion of the latter.

An inner sole is indicated at 4 and the v fore part 5 thereof has its edge throughout inset with respect to the sides and toe at the front portion ofthe last 1. The inset edge of the fore part 5, of the inner sole 4, is indicated at 6 and which provides a pair of shoulders 7. When the shell 2 is mounted in position the ends of the flange 3 abut against the shoulders 7. The rear part of the inner sole 4 is indicated at 8 and which is flush with the sides and heel of the last 1. The inner sole 4 is detachably secured to the bottom of the last 1 in a known manner.
