Application December 29, 1938, Serial No. 248,223

13 Claims.

Heretofore shoes have been regularly made with a welt attached to the upper, to which the sole of the shoe in the first manufacture of the shoe is attached by sewing, or to which a halfsole is attached by sewing in the repair of the shoe. It is now a common practice to attach the sole to the new shoe, or the half sole to an old shoe, by fastening thereon with cement. In such cases the sole or half sole is not sewed to the welt, but is cemented thereto. In such cases because the welt overhangs the last it will not be firmly supported thereby and extra support is needed therefor while the sole or half-sole is being attached thereto by cement under pressure.

The object of this invention is to provide a support for the welt of the shoe, so as to prevent it from yielding while the sole or half-sole is being fastened thereto by cementing under pressure.

Another object of the invention is to provide a support that can be quickly adjusted to a great variety of sizes and shapes of shoes.

Another object of the invention is to provide adjustment by which the welt support will be held firmly in place on the shoe and will give adequate support to the welt under pressure.

These and other objects of the invention will be illustrated in the drawings, described in the specification, and pointed out in the claims at the end thereof.

In the drawings:

As above stated, it is common practice to attach soles or half-soles to shoes by cement, and where the shoe is provided with a welt some extra support is needed for the welt to hold it up under the pressure that is placed on the sole while it is being attached to the shoe in the cementing process. For this purpose I provide special forms of welt supports which will now be described as follows:

The welt support shown in Figure 1 comprises a yoke I, Fig. 2A, having bifurcated ends 2 and 3, and 4 and 5, arranged in pairs, extending laterally therefrom and having brackets 6 and 1 extending upwardly therefrom. It also has a threaded opening 8 located centrally therein. Between the bifurcated ends 2 and 3 is pivoted the arm 9, and between the bifurcated ends 4 and 5 is pivoted the arm l8. Each of these arms comprises a long extension 9A and WA on one side of the pivot, and a short extension 93 and HOB on the other side of the pivot.

Threaded into the opening 8 is a stud II, on which is mounted to slide a block I2. Between the block l2 and the yoke l is provided a helical compression spring l3. Threaded on the stud is a wing nut I4 by which the block l2 may be moved forward toward the yoke l, the spring I3 being compressed between the two parts as they are drawn together. The ends of the block I2 are grooved, and in the grooves engage the short arms QB and "3B. The inner edges of these arms are cam-shaped so that they react in the grooved ends of the block l2 and are spread thereby as the block advances. This, in turn, causes the long ends 9A and 19A of the arms to be drawn together toward the shoe. On the long ends SA and "3A of the arms is pivotally mounted extensions l6 and I! which are adapted to engage in the groove between the welt and the upper of the shoe, and as the wing nut I4 is screw-ed forward it presses these extensions firmly in place, so that they act as a support for the welt while the last is in the shoe. In both the extensions l6 and H are provided holes. Through the hole in the extensions 16 the end of the cable I8 is passed and is fastened in place therein by a knot l9. This cable passes around the toe of the shoe and rests in the groove between the welt and the upper. in the extension I! and is drawn tight around the toe of the shoe by a mechanism that will now be described.

Mounted to turn in the brackets B and I is a shaft 20 having a wing head 2| fastened on the end thereof. The'bracket 1 has its outer face grooved with grooves 22 as shown in Figure 6. On the outer end of the shaft 20 is provided a pin 23 which engages in one or the other pairs of these grooves. On the shaft 20 is provided a washer or collar 24, held in place by a pin 25. Between this washer and the bracket 1 is placed a helical spring 26 which normally moves the shaft 20 down, as shown in Figure 5, and holds the pin 23 in engagement with the one or the other pair of grooves as shown in Figure 6. The cable I8 passes through a hole ISA in the shaft 29, and by turning the shaft 29 the cable is wound up thereon and is drawn tight into the groove between the welt and the upper of the shoe. The

cable is held in tension by the shaft, and the shaft is held against turning in the reverse direction by the engagement between the pin 23 and the grooves 22.

In regular operation a last is preferably usedsuch as is shown in a companion application Serial No. 240,085, filed November 28, 1938. This last, or any equivalent last, is inserted in the shoe and the welt support is then applied to the shoe, first by turning the wing nut l4 so as to bring the extensions properly into engagement with the shoe, and then the cable is adjusted to the shoe, and the shaft 29 is turned so as to put it under tension. In this way the welt is firmly supported from the last within the shoe so that it will not yield under considerable pressure.

The shoe shown in Figures 1 and 2 is a so-called ladys shoe with a high heel, but it will be understood that this support can also be used on childrens shoes, or ladies shoes provided with low heels.

In Figures 7 and 8 I have shown the welt support applied to a mans shoe. In these figures the parts at the right of the Welt support are all substantially the same as those shown in Figures 1, 2 and 5, the only difference being in the fact that the shaft 25! is preferably longer in a welt support used on a mans shoe than would be used in a welt support for a ladys shoe.

The long ends 90 and lilo are different from each other and are somewhat differently shaped from the arms 9A and IQA shown in Figure 1. This is due to the fact that the mens shoes are of greater width than ladies shoes and they are made with a deeper curve on the inside of the arch of the foot than is found on the ladies shoe. It is also true that while the welt support shown in Figure 1 can be used on either a right or a left shoe of the same pair, the welt support It passes through a similar hole 1 shown in Figure '7 must be specially made for each of the right and left shoe of the pair. The one shown in Figure 7 is the welt support used on the left shoe of the pair, it being understood that the welt support for the right shoe of the pair will be merely the reverse of the support shown in Figure '7 and being made symmetrical there-with.

On the outer end of the arm is pivotally mounted an extension 311 and rearwardly therefrom is also pivotally mounted an extension 3|. On the outer end of the long arm l to is pivotally mounted extensions 32 and 33 corresponding to the extensions 36 and 3!. These extensions swing free on the arms and engage in the groove between the welt and the upper and adjust themselves thereto as the arms are drawn together, as above explained.

Fastened to the extension-3i} is provided a cable 34 similar to the cable l8 above described, which passes around the sole of the shoe and through a hole in the extension 32. This cable then extends rearwardly and engages with the shaft 20, and is drawn tight around the toe of the shoe in the groove between the welt and the upper by turning the shaft 20, so that the welt is firmly supported thereby in the same manner as has been described in connection with the support used on the ladys shoe.

The extension 32 is shown in cross section in Figure 10, it being understood that all of these extensions 3i], 3|, 32 and 33 are wedge-shaped at the lower edge, as shown in Figure 10, so that they will project into and engage between the welt and the upper and will communicate the support of the last firmly to the welt.

In Figures 11, 12, 13 and 14 I have shown a modified form of the support for the welt of a mans shoe, although it is obvious that this can be adapted to support the welt of a, ladys shoe as well. In this modified form 40 indicates the yoke on which the two arms 4! and 42 are pivoted, which arms have the short extensions MA and 42A on one side of the yoke. The arms are drawn together by forcing the block 43 between the extensions MA and 423 by means of the wing nut 44 as heretofore described in connection with Figures 1, 5, 7 et cetera.

On the outer ends of the long arms 4! and 42 is pivoted eveners 45 and 46. On each of these eveners is pivoted extensions 45A, 45B, 46A, and 463. These extensions are adapted to engage between the upper and the welt of the shoe, so as to support the welt from the evener and the last within the shoe.

Mounted to turn in the yoke 48 is the shaft 41 having the handle 48 on the end thereof by which it can be turned. Between the brackets G and 1 on the yoke is provided a spring 26, which surrounds the shaft 41. On this shaft is a washer or collar 24 against which the spring presses. This collar is held against one-way movement on the shaft by the pin 25, so that the expansion of the spring pushes the shaft 41 down in Figure 14. In the bracket l is provided four grooves, similar to those shown in Figure 6 on the bracket 6, in which the pin 25 can engage and by which engagement the shaft is held against turning in any one of four positions in which it may be placed.

At 49 is provided a hole through which one end of the cable l8 passes. The other end of the cable is attached to one of the extensions, as indicated at 50 in Figure 11. This cable passes around the sole of the shoe between the welt and the upper and through a hole in the extension 45A, so that the welt is directly supported from the upper, which in turn is held firm by the last which is inside of the shoe. This cable is drawn tight by turning the shaft il. When the cable is drawn sufiiciently tight, the spring 26' will expand and force the pin 25 into one of the slots and thus lock the shaft against reverse movement.
