G. L. LAWRENCE, JR. RUBBER SHOE AND METHOD OF MAKING THE SAME.

APPLICATION FILED MAR-26.1920- 1,352,008. Patented Sept. 7, 1920.

I 3-3 designates the UNITED STATES 'PATENT' OFFICE.

GEORGE I. LAWRENCE, JR., OF MELROSE, MASSACHUSETTS, ASSIGNOR T0 BOSTON RUBBER SHOE COMPANY,

A CORPORATION OF MASSACHUSETTS.

RUBBER SHOE AND METHOD OF MAKING THE SAME.

Specification of Letters Patent.

Patented Sept. 7, 1920.

Application filed March 2c, 19 0. Serial No. 369,044.

. To all whom it may concern Be it known that I, GEORGE L. LAwRnnoE, Jr., a citizen of the United States, residing at elrose, in the county of Middlesex and .State of Massachusetts, have invented certain new and useful Improvements in Rubber Shoes and Methods of Making Same, of which the following is a full, clear, and exact description.

his invention relates to an improvement in turned edges on lumbermens rubber footwear, and is designed to provide .a neat and efiicient joint between the edges of the quarters and the edges of the tongue, as well as between the edges of the quarters and the vamp and the method of producing the joints.

This is accomplished by folding over the top and front edges of the rubberized fabric quarters,'which are provided on their outer faces with a comparatively thick coating of high-grade rubber, which high-grade rubber is disposed on' the inner sides of the quarters to the width of the folds. This enables a good, waterproofed bond to be formed between the quarters and the edges of the tongue, and between the quarters and the vamp.

The precise nature of my invention will be best understood. by reference to the accompanying drawings, it being obvious, however, that changes may be made in the form anddetails of construction of the shoe, without departing from the spirit and scope of my invention as defined in the appended claims.

In the drawings,

Figure l is an inside face view of two quarters after they have been connected to each other at the back.

Fig. 2 is a detailed sectional line 22 of Fig. 1, and

Fig. 3 is a perspective view of one form of shoe made in accordance with my invention.

in these drawings, the reference character quarters, 4 the tongue two of its edges to the view on the which is secured at edges of the quarters 3, which is also secured to the thereof.

The lower edges of the quarters of the shoe are also secured to the vamp 5 at the point 6.

In the manufacture of shoes in accordvamp 5 at the lower edge ance with my invention, the fabric from which the quarters are died is provided on its outer face with a relatively thick coating 7 of good rubber. The top and vertical edges ofthe quarters are then folded upon themselves as indicated at 8 in, Fig. 1, and the two quarters are connected to each other along their back edges as indicated at 9 to form the center of theback of the shoe. In Fig. 1 I have indicated at 8 a portion of the edge before it has been folded upon itself. After the, quarters are secured to each other, a tongue-forming portion is connected to each of the vertical edges of the quarters, so that the inner face of said tongue-forming portions engages the surface of high-grade rubber 7 which has been folded back upon itself, as clearly indicated in Fig. 2. Eyelets 10 may then be passed through the quarters and the tongue-forming portions along both the outer edges of the connected quarters, as indicated at the right hand side of Fig. 1, but if desired, buckle straps may be secured between the inturned edges of the quarters and the edges of the tongue-forming portions.

The shoe is then built up in the usual mannner, and the folded edges of the quarters are connected to the vamp at the points 6, and the shoes are then vulcanized.

By folding over the edges of the quarters. I am enabled to provide a good quality of rubber at the seams to form the joint between the edges of the quarters and the various members to which they are secured.

The advantages of my invention result from the provision of a vulcanized shoe having rubberized fabric quarters whose seaming fabric edges are turned upon themselves, to bring the good facing of rubber on the exterior thereof into contact with the other members to whichthe quarters are to be secured along the joints, and the method of forming the joint.

Having thus described my invention, what I claim and desire to protect by Letters Patent is:

l. A rubber shoe having rubberized fabric quarters vulcanized at their front edges to the edges of the tongue and the vamp, said quarters having the fabric and rubber along their outer front edges folded upon themselves to bring the outer rubber faces of the quarters into contact with the edge portions of the tongue.

2. A rubber shoe havin fabric quarters comprising the steps of dieing out quarters provided with a coating 0 rubber on their from rubberized fabric, then foldlng the outer faces and vulcanized at their edges to fabric edges of the quarters upon themthe tongue and vamp, said quarters having selves to bring a portion of the rubberized the fabric and rubber along their front outer faces of the quarters on the inner edges and tops folded upon themselves to faces at the edges thereof, then building said bring the outer coating of rubber into conshoe and placing said folded edges of the quarters in contact with the adjacent members forming the shoe, and then vulcanizing said shoe.
