GEORGE E. MCGORMACK, OF EAST BRIDGEVVATER, MASSACHUSETTS,

ASSIGNOR OF ONEHALF TO GEORGE E. ROLLINS, OF EAST BRIDGE- WATER, MASSACHUSETTS.

LEATHER BOOT OR SHOE.

SPECIFICATION forming part of Letters Patent No. 730,555, dated June 9, 1903.

Application filed February 28,1903. Serial Flo-146,473. (No model.)

To o whom it may concern:

Be itknown thatLGEoRGE E. MCCORMACK, a citizen of the United States, residing in East Bridgewater, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Leather Boots or Shoes, of which the following is a specification.

, This invention relates particularly to weltshoes; and it has for its principal object to provide means. for preventing the adjacent surfaces of the outer sole and welt at the instep or shank of the shoe from rubbing together or chafing as the instep bends, and thus wearing off or breaking the stitches.

In order to accomplish this result, I provide at the instep, between the welt and the outer sole next and substantially flush with the outer edges on each side, spacers or layers of rubber or equivalent elastic soft material,

through which the stitching extends and within which the knots or looking portions of the stitches are located. By this means the outer sole and welt are prevented from rubbing or chafing, there is no shearing edge to cut the stitches, and inasmuch as there is a considerable space between the outer sole and welt, which is occupied by the spacer, the stitches in the course of relative movement of said sole and welt do not bend suddenly at or nearly at right angles, but at very obtuse angles, as they extend from thefwelt through the spacer to the sole.

The nature of the invention is fully described below and illustratedin the accompanying drawings, in which- Figure 1 is a side view of a shoe embodying my invention. Fig. 2 is a bottom view of the same, a portion of the outer sole and heel being broken out. Fig. 3 is a cross vertical section taken .on line 3, Fig. 2. Fig. 4 is a vertical section along the line of stitching, taken on line 4, Fig. 2.

Similar letters'of reference indicate corresponding parts.

a represents the outer sole, 1) the welt, and c the upper, all constructed as usual.

(1 represents the line of stitching.

At the instep, between the welt andthe outer sole and flush with their outer edges on each side of the shoe, I provide an intermediate layer or spacer e of rubber or equivalent elastic soft material, such as felt, each of said spacers extending from the outer edge inward through and beyond the line of stitching, substantially as indicated in Figs. 2 and 3. The spacers extend for a sulficient distance toward the heel and toe to practically include and protect those portions of the lines of stitching in which there is relative movement of the outer sole and welt as the instep or shank bends. The spacers may extend inward as far asdesired, and their inner edges and ends grow gradually thinner in section, being beveled or skived for that purpose. When the shoe is sewed, the stitches (1 extend from the welt I) through the spacers e into the outer sole or, andthe knot or look of each stitch is embedded in this soft-rubber spacer.

When the shoe is used and the instep bends, there is no chafing or rubbing of the stitch between the adjacent surfaces of the welt and outer sole, as said surfaces are kept a suffi cient distance apart by the spacers. Hence there is practically no shearing edge to cut the stitch. Moreover, by reason of the thickness of the spacers the efiect on the stitch of any relative movement of the outer sole and welt is to merely bend the portion of Y the stitch which is within the spacer at a slight angle, it being evident that there can be no sharp right-angular bend, as is thecase when the adjacent surfaces of the welt and outer sole are in contact. The efiect of the cushioning-spa'cer on the stitch is to prevent friction and to prevent its being worn down or severed by a rubbing or chafing process, and the general efiect on the shoe is to impart flexibility and keep out moisture.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent, is-

In a boot or shoe of the character described, the combination with the outer sole and welt, of a spacer consisting of a layer of rubber or equivalent elastic soft material, said spacer being located at the instep between the outer g I I 730,555

In testimony whereof I have signed my A. N. BONNEY.
