Application filed March 2, 1915. Serial No. 11,528.

T 0 all whom' it may concern: y

Be it known that I, KARL A. STRITTER, a citizen of the United States, residing at Nahant, in the county of Essex-and State of Massachusetts, have invented certain new and useful improvements in Boots and Shoes of whichl the following is a specification.

MyV invention relates to boots and shoes generally but more especially to boots and shoes constructed with so-called artificial soles, that is, with soles made from material other than leather such, for example, as rubber. f

The object-of the vinvention is to provide an improved boot or shoe andparticularly an improved boot or shoe havlng an artlficial sole.'

My improved boot or-shoe' comprises a sole that is made with a marginal slit or recess which provides a iap upon the tread side of 'the sole covering the stitches which fasten the sole to the upper part of the shoe and also covering a iexible reinforcing strip which is laid into position within sald slit or recess and through which the sole attaching stitches are passed, the flap being preferably cemented down on top -of the reinforcing strip and stitches after the sole attaching stitches have been formed.

With -vthe'` constructions heretofore commonly employed inA manufacturing shoes withv artificial soles of rubber or the like, itV

has been found that the tension on the thread during the stitching operation would cause the thread to cut its way completely or partially out of the awl or needle perforations made in the sole for .the stitches and, moreover, the awll or needle would start a cut or fracture that would extend or grow under the constant flexing the sole receives in: use. Also the exing of the sole and the strain brought upon the stitches while the shoe was in use caused the stitches to cut the `material of the sole thereby loosening the latter from the upper. The reinforcing strip ofmy "improved shoe may be of any suitable material but it is preferably a tape of textile material and when incorporated inthe shoe it obviates the objections just referred to by preventing the stitches from cutting the material ofthe sole. -Furtherf more the flap on the sole not only shields the stitches 4but it also conceals the reinforcing strip, the latter being an item of some .importance. The strip and. stitch coverlng flap on the sole not only conceals the strip upon the tread side of the sole, particularly l when a textile strip is used. Also the appearance of the shoe is greatly improved by having the strip concealed.

Other features of my invention are hereinafter pointed out.

In the accompanying drawings z-Figure l is a plan view partly in section, of the -bottom of a shoe embodying one form of the invention. Fig. 2 is an enlarged section on the line 2-2 of Fig. l. Fig. 3 shows a piece of tape such as may be used in carrying out myI invention. Fig. 4 is a sectional view of the sole before it is applied to the shoe and before `it has been trimmed.

Having reference to the drawings, A represents the artificial sole of my improved shoe. This sole A, which may be made from rubber, is formed with a slit a extending from a point` back of the breast of the heel forward along one side of the shank, around the forepart and thence' rearward along the opposite side of the shank to a point just back of the breast of the heel. This slit is provided to accommodate a flexible reinforcing, strip B, which is preferably a textile tape although any other suitable iexible ma- -terial may be used. and when said slit is formed in the margin of the sole a flap a is simultaneously produced upon the tread side of the sole.

During the operation of stitching the sole to the -welt D of the upper portion of the shoe the flap a is held back out of the path of the presser foot and needle either by being turned back by the presser-foot as the latter advances or through .any other suitable means. As the stitching operation progresses the tape .B is delivered or guided into the recess formed by the slit just in advance of the needle and presser foot so that the sole attaching stitches C pass through said tape as well as the sole A and welt D. After the sole has been stitched to the upper part of the shoe the ap is folded and cemented down onto strip B so as to cover the latter and the stitches. The sole is then trimmed approximately upon 'the line -y, Fig. 4 after which the heel E is applied.

When the heel E is applied to the sole the breast of the heel is forward of the ends of the slit a and flap a so that the latter is protected against Wear and tear by the heel.

Herein I have shown my invention as embodied in a Goodyear welt shoe but without departing from my invention the same may be incorporated in other types or makes of boots and shoes. Furthermore, while I prefer to start and stop the slit a and strip as at points just back of the breast of the heel, it is to be understood that I do not limit my invention in this respect and the slit and reinforcing strip may extend around the sole to any desired extent.

If desired the textile reinforcing tape B may be secured within the slit a by cement or otherwise before the stitching operation is started, but in practice it has been found convenient to have the presser foot of the sewing machine constructed to serve also as a tape guide by which the tape is laid into the slit just in advance of the needle as the sewing operation progresses.

By using a tape of textile material the former may be of the desired thinness and yet have the required strength.

IVhat I claim is l. As a new article of manufacture, a sole formed with a marginal slit to accommodate a reinforcing strip and provide a strip covering flap, and a strip of reinforcing mate* rial Within said slit.

2. As a new article of manufacture, an artificial sole formed with a marginalslit to accommodate a reinforcing strip and provide a strip covering flap, and a reinforcin tape secured within said slit. v

8. A boot or shoe having its sole made with a marginal tape receiving slit which provides a tape covering flap upon the tread side of the sole; a flexible reinforcing tape secured within said slit, and covered by said flap, and sole attaching stitches sewed lhrough said tape and also covered by said 4. A boot or shoe having its sole formed with a marginal tape receiving slit which provides a tape covering flap upon the tread side of the sole; a tape of textile material within said slit and covered by said flap, and sole attaching stitches sewed through said tape and also covered by said flap.

5. A boot or shoe having a rubber sole with a marginal tape receiving slit which provides a tape covering flap upon the tread side of the sole; a flexible reinforcing tape within said slit and covered by said flap, the latter being cemented down onto said tape, and sole attaching' stitches sewed through said tape and also covered by said flap.

6. A boot or shoe having an artificial sole made with a marginal tape receiving slit which provides a tape covering flap upon the tread side of the sole; a flexible reinforcing tape within said slit and covered by said flap, the latter being cemented down onto said tape, and sole attaching stitches sewed 1t-lhrough said tape and also covered by said In testimony whereof I have aflixed my signature, in presence of two witnesses.
