To all whom it may concern."

Be it 1 citizen of the United States,

of Massachusetts, have invented a certain new and useful Improvement in Rubber- Soled Shoes, of which the following is a specification, reference being had therein to the accompanying drawings.

his invention relates to an improvement in rubber soled shoes in which the upper is made of canvas, chick, or similar material.

and the novel features thereof are pointed out nd clearly defined in the claims at the close of this specification.

In the drawings, Figure 1 is a side elevation of a finished shoe embodying the invention.

Fig. 2 is a side elevation top ready for the rubb to be attached.

Fig. 3 is a side elevation of the top after the rubberized strip is attached thereto by sewing ready to be lasted.

The top will be secured to the canvas top at all, thei eby avoiding all of inner sole bv cement, as shovvn at 8 applied the a ove mentioned objections which are to the lnner face of the canvas upper alon due to the construction when the rubber near its edge and to the inner sole itself strip laps on to the upper as above deand a light coat to the inner face of the scribed portion or the rubberized The invention. will be fully understood from the following description taken in connection with the accompanying drawings canvas top.

After the upper is attached to the inner sole, a suitable filler 9, as of rubberized cloth, is applied to the inner sole to level it off with the canvas which laps on to the inner sole. The rubberized strip may lap partially on to, the filler, and where it contacts with the filler it is cemented, but only a very thin coating of cement is used, whereas under the old method of forming the shoe, the rubber strip required two heavy coats of cement all over its inner face.

The shoe is now ready for the outer sole which has a coating of cement applied to the inner face thereof, and a thin coating of cement will be applied to the proximate face of the filler and that portion of the outer face of the rubber strip which is turned over on to the bottom. The outer sole 10 is then firmly cemented to the filler and to the said turned over portion of the rubber strip, as shown in Fig. 6. The outer sole preferably extends on all sides some distance outwardly beyond the exposed portion strip so that the said exposed portion ofthe rubber strip is merely a narrow portion of the fold, which looks like a bead or welt, and the shoe has the and there is no lap over portion of the rubber strip on the canvas top. The lap portion is all inside, lapped between the filler and the outer sole. After the cement is properly dried the shoe is vulcanized in the usual manner.

VVha-t I claim is:

1. A rubber soled canvas shoe having a canvas top, a rubber outer sole, an inner sole, and a strip of rubberized cloth having one edge extending in between the inner and outer soles, the other edge being secured to the top along the lower edge of the top and forming an exposed bead between the top and the outer sole.

2. A rubber soled canvas shoe having a canvas top, a rubber outer sole, an inner sole, and a strip. of rubberized cloth folded over and secured through the fold to the top of the rubber I appearance of a welted shoe.

:. along the lower edge of the top in such position that when the shoe is completed the fold will form a bead between the top and the outer sole, the other edge of the strip extending in between the inner and outer sole and secured therein.

3. A rubber soled canvas shoe having a canvas top, a rubber outer sole, an inner sole, and a strip of rubberized cloth secured to the top along the lower edge of the top in such position that when the shoe is completed the rubberized strip lies between the inner sole and the outer sole with its outer edge exposed and forming a llIie of union between the top and the outer so e.

4. In a rubber soled canvas shoe, a canvas top, a rubber outer sole, an inner sole, a filling between the inner sole and the outer sole, and a strip of rubberized cloth folded over at one edge and secured by suitable fastenings through the fold to the outer face of said canvas top around the lower part thereof, the other edge of said rubberized strip extending in and being lasted between the said inner sole and outer sole, the said folded edge of the rubberized strip appearing in the finished shoe as a bead between the outer sole and the canvas upper.

5. A rubber soled canvas shoe having a canvas top, an inner sole, a rubber outer sole, and a strip of rubberized cloth folded over near one edge and secured to the outer face of the canvas top by suitable fastenings which pass through both thicknesses of the fold and through the canvas top leaving the edge of the fold exposed as a bead between the canyas top and the outer sole, the inner edge of the said rubberized strip extending inward farther than the folded edge and being lasted in between the inner sole and the outer sole.

In testimony whereof I affix my signature.
