SLIPPEE.

Patented Nov. 28, 1916.

Original application filed August 31, 1915, Serial No. 48,216. Divided and this application filed July 18,

1916. Serial No. 109,986.

To all whom itmay concern:

Be it known that I, ERNEST A. BICKFORD, a citizen of the United States. residing at Worcester, in the county of lVorcester and State of Massachusetts, have invented a new and useful Slipper, of which the following is a specification.

This invention relates to a slipper and, while not strictly confined thereto, is particularly adapted for a slipper made almost entirely of felt.

The principal objects of the invention are to provide a simple and practical slipper in which preferably the insole and upper are integral with each other throughout; to provide a slipper in which there is no seam be tween the insole and upper so that there are no stitches at that point likely to pull out, and also to provide a cushion without complicating the manufacture or materially increasing the expense.

Reference is to be had to the accompanyings, in which Figure 1. is a side elevation of a felt blank from which the slipper is to be made; Fig. 2 is a cross sectionof the same shown bottom side up and showing the first step in the method of manufacture after the blank is formed; Fig. 3 is a similar view showing the outsole stitched on; Fig. 4c is a similar view showing the next step, the application of the cushion. and Fig. 5 is a cross section of the complete slipper.

1 shows simply a felt blank from which the silpper is to be made. This, as shown, consists of a single integral piece of material, preferably felt, embodying an upper A and an insole B. This article is formed at a single operation, as by a felting process, and preferably the insole is made of the same thickness and texture as the upper. In order to manufacture a slipper from this blank as shown in Fig. 2 the insole is slit from end to end. This makes two flaps of the insole which can be turned up as shown more especially in Fig. 8. This is taken advantage of for the purpose of applying the outsole D. This outsole may be soft, hard, thick or thin as desired. In any case when applied as shown in this figure, it is inserted through the slit and its edges are stitched to the blank AB along the boundary line between the insole and upper respectively, 2'. e. the line where they merge. In the case shown in the drawing this outsole is of a comparatively thin leather, and consequently its edge can be turned up and in slightly in order to sew it. Another step in the preferredway of manufacture is indicated in and then the slipper is turned and the product shown in Fig. 5 is the result. It will be seen that this results in an article in which there is not necessarily any seam between the insole and upper, and consequently no stitches are likely to come out at that point. Furthermore, the insole preferably is integral and continuous with the upper, thus forming a convenience in manufacture, reducing the cost, and leaving a smooth bottom which can he covered if desired as is understood in this art. Another great advantage is that the only seam between either of the soles and the upper is located inside the shoe where it cannot come to wear and cannot be seen from the outside, and this is a seam not between two edges but between one edge of the outsole and the body of the upper. In this way an extremely neat and durable article is provided at a comparatively small expense.

It will be understood, of course, that in the manufacture of the slipper the cushion can be omitted if desired in certain classes of slippers or it can be secured to, or form a part of, the outsole before the latter is placed in position, and the same procedure can be carried out with a blank in which the insole and upper are sewed together.

Although I have illustrated only one form of the invention I am aware of the fact that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction herein shown and described, but

lVhat I do claim is 1. As an article of manufacture, a slipper comprising an upper and insole, and an outsole secured to the insole by a line of stitches located entirely within the slipper,

having one side of the line of stitches located on the inside of the upper and insole, and the other side located on the outside of thle insole but on the inner side of the out SO e.

2. As an article of manufacture, a slipper comprising a felt upper and insole integral with each other, said insole being slit from end to end and sewed up, an outsole secured to the insole by a line of stitches entirely concealed from the exterior of the slipper, and a cushion located between the outsole and insole.

3. As an article of manufacture a slipper comprising an upper, an insole integral therewith, and an outsole secured to the insole by a line of stitches located entirely within the slipper so thatsaid stitches cannot come to Wear on the exterior surface of the slipper said insole having a slit therethrough to permit access to the stitches, and the slit being sewed up.

In testimony whereof I have hereunto aflixed my signature.
