METHOD OF MAKING SAME Application filed February 2, 1981.

My invention relates to new and useful improvements in shoes and the method of ma ing the same, the primary object of the invention being to provide an improved method of making womens shoes so that the shoe when completed will give the effect of what is known as a turned shoe, but in effect is made similar to a shoe produced by what isknown as the cemented shoe process, yet

differs from both of them and overcoming the many objectionable features of both of the aforesaid shoes.

A further object of the invention resides in providing a method wherein but asingle sole is used, thus eliminating the objectionable features of an inner sole, such as is used in the McKay process, the cemented shoe process and similar processes.

A further object of the invention resides in the provision of a process for making shoes which will produce rigidity and strength at the portions thereof requiring the same but which will eliminate unnecessar-y thicknesses at the portions of the shoe where thinness and lightness are most desirable. I

A further object ofthe invention resides in providing a shoe which is light in weight, durable under the heaviest wear and one which will avoid squeaks.

Still another object of the invention re sides in using a single sole from which is cut a marginal sole strip applicable to the last and to which the upper is secured prior to the application of the sole proper.

With these and numerous other objects in view, my invention consists in the novel features of construction, combination and an arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

Figure 18 is a transverse section through the toe portion of the shoe completed in accordance with my improved method.

In describing the invention, I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views and in which the numeral 1 designates a sole to which is applied the first step in my improved method which consists in channelling the ball portion thereof to form a marginal strip designated by the numeral 2, the channelling being accomplished with the usual Goodyear universal channelling machine utilizing knives known under the numbers 922L and 62. The next operation involves the removal of thestrip 2 from the sole which is accomplished by using what is known as a duplex feather edge shank producing machine, model A, with knives S, well known to the trade. In Figure 4, I have disclosed the marginal strip removed from the sole 1 and in Figure 3, I have disclosed the sole after said strip 2 has been removed therefrom.

prior to the application The sole is then smoothed and a heel portion thereof split as shown at 3 in the drawings, this being accomplished in the usual or any preferred manner. The edges of the sole throughout its length are then feathered in the usual manner. The process now-leads to the application of the elements to the last.

The lastin the drawings is designated by the numeral 4 and secured to this lastby temporary tacking as shownat 5 is a shank member 6. Applied to the ball portion of the last 4 is a sheet of paper or the like 7 which is utilized to cover that portion of the last to prevent glue or compo from adhering to said last. Applied to the ball portion of the last over the paper 7 is the marginal strip 2, this application bein a temporary one through the medium 0 the tacks or nails 8, as clearly shown in Figures 10 and 11 of the drawings.

The upper 9 is then lasted, being applied in the usual or any preferred manner, preferably being glued under the usual cementing method to the marginal strip 2 and to the shank member 6 and temporarily nailed or tacked by means of the nails or tacks 10, as clearly shown in Figures 12 and 13 of the drawings. The upper secured to the last in this manner is allowed to remain over night, or as long as may be necessary to accomplish the desired results, whereupon the tacks are removed. The shoe in this step of the process is disclosed in Figures 14 and 15,. A metal shank member 11 of the usual formation and as is usually applied to use in shoes of this character is then applied to the shank member 6. The shoe is then ready to have the sole erable. A lining, of course, is applied to the last along with the upper, as usual, and after the heel hasbeen properly applied in the usual manner, (not shown) a sock lining may be applied to the sole on the inside of the shoe in the usual manner, such lining in Figure 18 being designated by the numeral 12.

It will thus be seen that a shoe is constructed which is composed of but a single sole but which will give the desired effect of two soles, so far as rigidity and strength is concerned and yet have the lightness of a single soled shoe as well as the many desirable features of the turned shoe.

From the foregoing description of the method of constructing my improved shoe, the steps in the process of construction and the structure of the shoe in general will be readily understood and it will be seen that I have provided a comparatively simple, inexpensive and efficient means for carrying out the objects of the invention.

While I have particularly described the elements and steps best adapted to perform the functions set forth, it is'obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing' any of the principles of the invention.

Having thus described the invention what is claimed is:

1. The method of constructing a cemented shoe consisting in providing a sole of the desired final sole thickness in the finished shoe, removing from the edges of the upper surface of the ball section and adjacent portions of the shank section of the sole a rand of less thickness than the sole and reducing the thickness of the shank and heel portions of the sole, by removal of material from the upper surface thereof, to the thickness of the marginal portions of the ball section thereof, applying ashank piece and said rand to a last and securing the terminals of the rand in overlapping relation to the forward end of the shank, lasting an upper and permanently securing the same to the rand and the edges of the shank, and permanently attaching the sole to the upper, the rand, and the shank without delasting the shoe.

2. The method of constructing a cemented shoe consisting in providing a sole of the desired final sole thickness in the finished shoe. removing from the edges of the upper surface of the ball section and adjacent portions of the shank section of the sole a rand of less thickness than the sole and reducing the thickness of the shank and heel portions of the sole, by removal of material from'the upper surface thereof, to the thickness of the marginal portions of the ball section thereof, lasting-an upper upon a last to which said rand and a shank piece to which the rand is secured have been applied, and permanently securing the upper to the rand and the edges of the shank piece, and permanently attaching the sole to the upper, the rand, and the shank without delasting the shoe.

In testimony whereof I aflix m signature.
