This invention relates to shoe repair or manufacturing and more particularly to a harness for facilitating the assembly of soles to the Welts of shoes and boots.

It is an object of the present invention to provide a new and improved shoe harness for fastening welt and sole together that will avoid one or more of the disadvantages and limitations of the prior art.

Another object of the herein described invention is to provide a new and improved shoe harness for fastening welt and sole together that will be simple in structure and its mode of application, as Well as economical to use.

An additional object of the invention is to provide a new and improved shoe harness for fastening welt and sole together, that may be used with or Without a last and will have adjustments to permit it to be employed for a substantial range of sizes of shoes or boots.

Other objects will become apparent as the invention is more fully set forth.

For a better understanding of the invention reference is made to the appended drawings and the following description, which together portray a particular form of the invention by way of example, while the scope of the invention is more particularly pointed out in the claims.

Figure 11, is a view of the jaw members blown up to show the construction thereof.

Similar reference characters refer to similar parts throughout the drawings.

In the construction indicated, a conventional low cut shoe i8 is employed to illustrate the operation of the device based on this invention.

The structure consists fundamentally of a plate i I to press against the sole l 2 to be applied to the welt E3 of the shoe, on the outer surface thereof. To keep the welt ii! in place during the time that the plate It is engaging the sole, a series of jaw members if supported on a connecting strap H are applied on the projecting surfaces of the welt located farthest from the sole. The plate H and the strap and members are drawn tightly towards one another by individually spaced jacks i8. These jacks are suitably screw threaded and provided with wing nuts to do this in an efiicient manner. To permit adjustment and a certain amount of freedom, open slots 19 are arranged in the members l5 and quasi-elliptical holes 20 in the plate l I. These holes and slots are aligned with each other and spaced around the plate and strap to produce an even pressure over the whole peripheral areas of the sole and welt that are involved in the operation. The strap H is made of separate segments of material of suitable width, as shown in Figures 8 and 9, the joints 2| between them being suflicient to allow a reasonable amount of play and lateral adjustment when the end portions 23 are drawn together by the operation of the wing nuts 24 on the stud 22, to bring the latter closer or further apart. The members I5 are slidably attached to a clamp l6 and plate 9 by screws and are. connected to the strap 51 so as to lap over the joints 2i and are screwed therein to give flexibility thereto.

In order to furnish a sup-porting structure for the whole unit, a front frame is made up, having plural legs 25 bent and spread apart into U-shape and restricted at the junction element 26 as indicated in the drawings. A rear frame is made up, having plural legs ll) with flanged bottom portions ll. The upper portion 42 is restricted at its junction element 43 as indicated in the drawings. The lower portion 44 of the portion i2 is bent inwardly and upwardly at 45 and provided with toothed slots 46.

In addition the elements 26 and 43 are arranged with lateral connecting arms 21 and serving to lap with one another and form an adjustable link between the legs and thereby provide a homogeneous frame. The elements 26 are tapped for tighteners 28 that align and engage with holed bosses 29 mounted on the upper surface of the plate H. The screwing of the tighteners enable pressure to be applied to the plate i i when it is against the shoe H]. The legs 25 are coupled together with hinges 30 that enable them to be swung out or into the framed form over the shoe disposed within it. They are held positively in the framed position by a catch strap mounted on one leg and engaging with a pin 52 on the other leg when swung over so that its slot 3| slides over the pin 52. One set of the legs 46 are braced together by a crosspiece 32. This cross-piece is low enough down on the legs to prevent its obstructing the placement of the shoe on the frame and is provided with tongs 38. It is braced rigidly and supports, a stem 33 which has a changeable shoe last 34 secured to its upper end for insertion in the shoe Ill. The stem 33 is supported at its lower end: by a plate 41 having slots 48 at its rear end to. engage with tooth slots 46 and slots 48 at its front end to engage with tongs 38. Theshoegis: fitted on the last and rendered rigid and straight, so that the pressure of the tighteners 28 will be counteracted to press the plate ll against .the sole and welt in between them and bring them tightly together while the cement used to stick them together is infusing and drying. The bottom portions 36 of the front legs 25 are flanged to enable them to stand upright more appropri-,-.. ately. The last 34 and stem 33are connected to, the cross-piece 32 so itmay be tilted, as shown in' Figure 4 and move the last 34 likewise This is particularly desirable when the last is inserted in a shoe. The unit avoids consideration of the heel of the shoe, as such is attached by another method not involved in the use of this invention.

The device forms a harness unit for a shoe and is adjustable to the width of the shoe to be assembled, and the pressure is afforded in plural ways that the edges and the central area of the sole and welt may be properly impressed duringv the process and independently of each other. It is readily emplaced on a shoe and its operation is facilitated by the simple structure employed. It is not complicated, and is of a portable nature. It may be used on a great variety of shoes of all kinds of shapes, since itsadjust mentsmeet requirements in width without requiring changing of the holding and pressing elements in the structure. These elements however are so arranged that they may be replaced for any reason that make it desirable, and this without changing the frame or main parts of the construction.

In the operation of the device the connecting strap l? and jaw members are positioned over the welt 13 of the shoe as shown in Figures 6 and 7. The shoe is then positioned on the shoe last 34, and a coating of adhesive is applied to the shoe surface, and to the underside of the sole which is then applied to the shoe. The plate H is then applied to the sole, the rear screw 28 isslightly tightened and the front frame which is'in open position as shown in Figure 2, isthen closed causing the lateral connecting arms 21 and to align with each other. The tighteners 28 are turned to, contact the plate I! and forces the sole and. welt together. and holds same Until the .-jacks attache.d .to .theelliptical- 1. 01 35 29.816. slid into the .open slots 19 and the wing nuts; 1.4, tightened to hold the welt. and. sole togethenwith practically the same amount of force as applied to the sole by the tighteners 28 as shown in Figure 1.' The tighteners are then turned in a reverse direction and the frame is swung on its hinge 3H and the shoe with the plate I! and the connecting strap attached to it is then removed from the shoe last 34 and is then set aside until the adhesive has dried. The operation is then repeated on the other shoe. To remove the last 34 from the machine, the last is tilted as shown 4 in dotted lines in Figure 4, this tilting causes the plate 41 to lift off the tongs 38 and the slots 48 allow the plate to swing in the tooth slots 46 and be removed therefrom. The shoe last may be removed from the stem 33 and another substituted in its place.

While but one general form of the invention is shown in the drawings and described in the specifications, it is not desired to limit this application for patent to this particular form or in any other way otherwise than limited by the scope thereof, as it is appreciated that other forms of construction could be made that would use the same principles and come within the scopeof the appended claims.
