BOOT oR SHOE.

SPECIFICATION forming part of Letters Patent No. 728,679, dated May 19, 1903.

Application filed March 13,1902. Serial No. 97,978. (No model.)

To all whmn it may concern:-

Be it known that I LOUIS A. DANIELS, of l-Iaverhill, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Boots or Shoes and Methods of Making the Same, of which the following is a specification.

This invention relates to boots and shoes in which the upper and sole in a turned boot or shoe and the upper, inner sole, and welt in a welted boot or shoe are united by a single thread having a series of loops inserted through the upper or through the welt and upper and through the between substance of the sole and locked by tongues formed on the sole. In Letters Patent of the United States No. 242,328, dated May 31, 1881, a boot or shoe of this class is shown, the locking-tongues being formed by making inclined V-shaped incisions in the sole, each tongue being independent of and isolated from the others. This formation of the tongues makes it necessary that the entire tongue be formed before the needle advances to penetrate the between substance and draw the loop therethrough. It has been found practically impossible to give the tongues a uniform length and width by cutting them in the manner above indicated, since very slight changes in the relative positions of the sole and the V-shaped cutter cause a marked change in the length, width, and thickness of the tongues. There is a liability, therefore, of making some of the tongues so short and attenuated that they will not properly engage and lock the loops. It has also been found difficult to secure proper registration between the needle and the tongues as heretofore formed. Owing to the difficulties above indicated the tonguelock system has not thus far been practically successful.

Myinvention has forits object to enable the tongues to be made practically uniform in size and shape, and therefore to uniformly engage theloops. ThisresultIaccomplishbyforming the tongues by two operations, one performed before and the other after the entrance of the needle into the sole, the first operation consisting in the formation of the usual channel in the surface of the sole, while the second consists in the formation of transverse'slits in the channel-lip after the needle has entered the channel, the operation of completing the tongue being simplified, so that it can be successfully and practically performed by cutters following the needle and accurately defining the edges of the tongues with reference to the loop subsequently drawn through the between substance by the needle, the length and thickness of each tongue being accurately defined by the channel.

The invention consistsin the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a perspective sectional view showing the toe portion of a boot or shoe embodying my invention. Fig. 2 represents a section on line 2 2 of Fig. 1. Fig. 3 represents a perspective view of the sole as it would appear if separated from the upper. Figs. 4. and 5 represent perspective sectional Views showing different stages of the operation. Fig. 6 repre sents a sectional View of a welted boot or shoe embodying my invention.

The same reference characters indicate the same parts in all the figures.

In Figs. 1 and 2 of the drawings, a represents the sole, and b the upper, of a turned shoe, said parts being shown in the positions they occupy when first assembled, the sole and upper being wrong side out. The sole has a cut or channel a formed in one of its sides, the mouth of said channel being formed in the face of the sole farther from the edge of the sole than the bottom of the channel, the said bottom being separated from the margin of the sole by the usual between sub stance. A lip a is thus formed, said lip con stituting the outer side of the channel.

In connecting the sole and upper a series of loops 0' are drawn from a single thread 0 through the between substance by a curved needle fof the kind ordinarily used in turned or welt shoe machines, the needle entering the channel during its forward movement and then penetrating the between substance. The continuity of the channel enables the needle to readily find and enter it and reach the between substance. After the needle has entered the channel and while the portion of the channel immediately above the needle is supported and somewhat raised by the needle, as shown in Fig. 4, so that said portion is somewhat stretched or distended by the needle, and thus held under tension, I out two slits 3 3 in the lip at opposite sides of the needle, as shown in Fig. 5, said slits forming the edges of a tongue 0 the top and bottom surfaces of the lip constituting also the top and bottom surfaces of the tongue. When the projected needle has engaged the thread 0, it is retracted and draws a loop 0 through the upper and the between substance, the loop being s'ubseq uently cast 03, thrown over the tongue a and taken up, the result being the locking of the loop by the tongue. The above-described operations are repeated until the upper and sole have been connected by a series of loops 0' and tongues 0, The needle may be operated by hand, the slits 3 3 may be cut by a hand-knife manipulated by the operator, the thread may be engaged by hand with the barb of the needle, and the loop may be cast OE and taken up by hand, although, of course, in practice these operations will be performed by a suitable machine.

In-Fig. 6 Ishow awelted boot or shoe united in the manner above described, a being the inner sole and f the welt.

It will be seen that the channel formed in the sole before the sewing or loop-forming 0peration accurately defines the length and thickness of the tongues, while the slits define the width of the tongues. All the tongues are therefore made uniform in size and shape, so that all the loops are uniformly engaged and locked.

I claim- 1. A boot or shoe sole having a lip formed by cutting a channel in one side of the sole, the bottom of said channel being separated from the edge of the sole by between substance, said lip having slits converting portions of it into loop-locking tongues.

2. A hoot or shoe comprising a sole having a lip formed by cutting a channel in one side of the sole, the bottom of the channel being separated from the edge of the sole by between substance, said lip being divided crosswise to form tongues, an upper, and .a soleand-upper-uniting thread having a series of loops extending through the between substance and engaged with said tongues.

In testimony whereof I have affixed my signature in presence of two witnesses.

LOUIS A. DANIELS.
