' WELT FOR BOOTS AND SHOES.

Specification of Letters Patent. v

Patented July 5,1910.

To all'abhom it may concern:

Be it known that I, Gnoncn F. Dunn, a

citizen of the United States, and aresideiit of Brockton, in the county of Plymouth and State of Massachusetts have invented an for Boots and Shoes, ofwhich the following description, in 'con nection with the accompanying drawings, is

a specification, like numerals on the drawings representing like parts.

This invention relates to welts for boots and shoes as an article of manufacture.

In order that the principle of my invention may be readily understood, I have disclosed one illustrative embodiment thereof in the accompanying drawing, wherein Figure 1. is a vertlcal cross sectional view of a boot or shoe having my welt applied thereto; Fig. 2 is a plan view of a' welt embodying my invention; Fig. 3 is an edge view 0 tion on an enlarged scale of said welt; and Fig. 5 is a similar view showing the same applied to a shoe.

Welts have, previous to my invention been made of indeterminate length and sol as articles of manufacture for use in McKay and Goodyear boots and shoes. Such Welts.

have in certain instances been proyided upon their inner edges with projections or teeth, as shown for example in the patents to Wm. B. Arnold, No. 646,592, and No. 674,831.

While welts constructed inaccordance with said patents have been found efiicient for the purpose intended, my present invention seeks to im rove the same in some respects, but is ca a le of embodiment in welts generally, w ether or not they be provided with teeth or projections and whether or not such teeth or projections be of the character disclosed in said patents. Preferably, however, the welt in which my invention is embodied is rovided with projections or teeth not only or the pur ose of saving stock, as

will be further described, but because of the peculiar coiiperation of said teeth or proections with other features of the invention.

Welts constructed in accordance with the patents referred to as well as other weltssaid welt; Fig. 4 is a vertical sec-.

the insole it has been customary to provide a guide for said stitches in the form of a channel or groove into which the sewing threads are sunk,'so that they will not be encountered by the stitching-threads that secure the outsole to the welt.

In accordance with my invention, I provide a piping strip of leather and stitch said pipin strip to the welt by a line of stitchin threa s adjacent the inner ed es of sai piping strip and welt and there ore passing through the teeth or projections upon the inner edge of the welt if, as preferred, the

latter be provided. Whether or not the channel in the lower face of the welt be provided and whether or not the inner edge of the welt be provided with teeth or pro- ,jections, the i ing strip and the welt,'having previous y een stitched together as described, are secured to the insole by a line of sewin threads positioned between said line of stltching threads and the outer edge of the welt and pipin strip. In this manner, the sewing threa s, which are customa rily chain stitching, are reinforced by the stitching threads, and in the event that the sewing threads break in the manufacture of the shoe or in its use or more especially if they break in the repairing thereof, the de-' scribed line of stitching threads securing the pi ing strip to the welt will continue to ho d the piping strip and welt together.

Referrin more particularly to the drawing, the we t, who is of suitable material, is indicated at 1 in the several figures, it being preferably made of indeterminate length as an article of manufacture. sired, the under face ofsaid welt may be provided with a channel groove 2 to receive the sewing threads, but it is unnecessary because the threads'which secure the outsole If deto the welt are positioned entirely outside the piping strip and cannot therefore interfere with the line ofsewing threads securing said welt to the insole. In other words the piping strip-acts as a spacin means between the line of sewing threa s for the insole and the line of sewing threads for the welt is provided with teeth or pro ections 3, such as shown in my co-pending appllcation Serial No. 47 6,650. It will therefore be understood that the toothed edge of the welt is of reduced thickness and that a very mate outsole. Preferably the inner edge of the edge of the welt.

rial saving is effected in cutting the welts from a strip by the formation ofteeth as disclosed in said application.

While the saving of stock is important in the formation of welts and for that reason it is important to sever the welt strips from each other by teeth 'as described, it is of very great importance that the inner edge of the welt be of reduced thickness whether th1s reduced thickness be effected by the formation of teeth or otherwise, because having formed the inner edge of the welt of reduced thickness, I may secure the inner edge of the piping stri thereto and yet the combined thickness 0 the inner edges of the Welt and the piping strip will not be too great to prevent both being fed as a un1t through the usual welt guide or manipulated as a unit. It has heretofore been suggested that a filling strip and a welt may be cemented or otherwise attached prior to the manufacture of shoes. but so far as I am aware. this has never been done in practice, for prior to my invention when a piping strip has been secured to a shoe the piping strip and the welt have been fed through separate guides to the shoe. This necessitates a cumbersome and awkward mode of procedure and has never met with favor. In fact, the objections have been so serious as substantially to preclude the use of piping strips with welts. In accordance with my nvention, however, the thin edged welt and previously secured piping strip may be fed as a un1t through a sin 1e welt guide and may be secured to the s cc as readily as welts devoid of piping strips have heretofore been secured.

The piping strip is indicated at 4 in the several figures and is composed of leather and preferably of the best quality. The said .piping strip is folded uponitself and incloses at its outer ed e a suitable thread 5, which preferably is o braided cotton. The inner edges of the piping strip are cemented together. It is important that the piping strip should snugly embrace the thread 5 at all points. This cannot be effected by the use of cement alone, as the cement cannot extend into close proximity to the thread 5, and moreover there is a tendency of the faces of the piping strip to separate from each other ad acent such thread. I secure -a rmanently rounded bead like effect by a ine of stitching Gextending through both portions of the piping strip as close as practicable to the thread 5.

The welt and piping strip are secured together by a line of stitchin threads 7 extending the entire length 0 the welt, said stitching threads passin through the thin It wi 1. be apparent that were the inner edge of the welt of the full thickness of the body thereof, this line of stitching would so increase the combined tion. In other words, it is not necessary to alter the machines in order topermit the use of my improved combined welt and piping strlp.

The combined piping strip and welt pre pared and secured together as described are secured to the insole 8 which is provided with the usual stitch receiving and retaining channel 9 and shoulder 10, the latter receiving the edge of the upper 11 in the usual manner. The combined welt and piping strip having been applied thereto in the manner indicated in Fig. 1, the several parts are secured by a line of through and through sewing threads as indicated most clearly at 12 in Fig. 5. The said sewing threads are customarily of chain stitching. These sewing threads sometimes break in the sewing operation, but much more often in the use of the shoe and articularly in re airing the same. After the shoe is finishe the'welt is held in position by the said line of sewing threads which secure it to the insole and also by the threads securing the welt to the outsole. If the said line of sewing threads 12 should break at one or more points, the welt would still remain held because secured to the outsole, but the. piping strip would be released from the welt at one or more points, were it not for the provision of the line of stitching threads 7 ,which secure said piping strip to the welt. Therefore saidline of stitching threads not only serves to secure the piping strip to the welt, but also to reinforce the action of the line of sewing threads 12. The line of stitching threads 7 being positioned between the line of sewing threads 12 and the inner edge of the welt not only are far less subject to reakage than the line'of sewing threads, but being ositioned as stated they do not interfere with the application of the sewing threads 12 when securing the welt to the insole.

It will be apparent that when my combined pipin str1 and welt is used the line of sewing a s securing the welt to the outsole is necessarily positioned outside the outer edge-of the piping strip, and hence is so far removed from the line of the'sewing threads 12 securing the welt to the insole that'tliere is no danger of interference of said two lines of threads, and hence there is no need of providing the channel 2 to receive and position said line of sewing threads 12.

Inasmuch, however, as many workmen are accustomed to use welts having a channel strip be secured thereto, thecombined p: strip and welt present a sufficiently fiexi descriptive sense and not for purposes Correct'ion in Letters Patent No. 963,694.

and prefer to operatetherewith, I may and preferably do provide such channel.

It is a parent that by providing the welt with test or projections, or otherwise fashioning' it with a thin ed e, the welt is reng dered more flexible at said ed e in its own plane. Therefore even thong the piping 1ng einner edge to permit themto be bent as a unit about the toe of the shoe and properly a plied and secured thereto. In other words, the combined inner edges of the welt and piping stri are substantially as flexible and as easy 0 application to the shoe as the unthinned edge of the usual-welt. Moreover, the piping strip conceals the teeth or projections and infect is secured thereto and serves to position the same. Therefore, the welt may be fed through its guide without any possibility of the entangling of said teeth in the guide or any other parts of the mechanism.

-The piping strip is secured to the grain face of the welt and not only enhances the appearance of the shoe but renders the same substantiall water tight because the piping strip is we ged as it were, inbetween the welt and the upper in such manner as to prevent access of water at that point.

' Having thus described one illustrative embodiment ofmy invention, I desire it to be understood that although specific terms are employed, they arense in a generic 811% o limitation, the see e of the invention being set forth in the 0 owing claims.
