PRESSINGr-FORM.

Application filed January 8, 1916.

To all whom it may concern.'

Be it known that I, HERMAN A. DAVEN- ron'r, a citizenof the United States, residing at Brockton, in the-county of Plymouth and State of Massachusetts, .have invented certain new and useful Improvements 1n Pressing-Forms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to pressing forms for sole laying machines, and more particularly to pad locators for such pressing forms.

The pressing pad on the forms of a common type of sole laying machine is held in position in a support, having flanges to hold the pad from transverse movement and a series of screws which pass through the flanges and into the pad to hold the pad from longitudinal movement. The pad is generally made of a yieldable material such as rubber, and the use of screws for holding ,such a material in the support is not satisfactory. Pads having different contours are used for dierent classes of work, and when they are fastened in place by screw-s they cannot be readily replaced. The pad for regular work has high places or bunches to engage the inside and outside shank of a shoe, and for treating shoes having long and short shanks the position of the bunches must be changed. The adjustment for changing the position of the bunches of the pad is not very great, and when using screws the pad becomes pierced with a large number of screw holes which are close together, so that the screws do not effectively hold the pad in position.

The primary object of the present invention is to provide a locator for the pressing pad of a pressing form which is efficient in its operation and will overcome the objectionable features noted above. To this end the invention consists in the pad locator for pressing forms which is hereinafter described and set forth in the claims.

The various features of the invention are illustrated in the accompanying drawings in which Figure 1 is a plan view of a sole pressing form embodying the preferred form of the invention; Fig. 2 is a side elevation mostly in section of the form shown in Fig.

Specicationof Letters Patent.

Serial No. 70,953.

1, and Fig. 3 is an end elevation of the pressing form.

The pressing form illustrated in the drawings is vof the same general type as lthe pressl ing form shown in my prior Patent No.

942,133, dated December 7, 1909. The form comprises a series of relatively movable supports 10 whichare mounted to give an equalized pressure lon the sole. Each one of the movable supports has an upturned flange 12 on each side so that the pad may be placed between the flanges and held from transverse movement. Y

'Ihe pad 14: illustrated in the drawings is a continuous rubber pad having a leather facing 16. To hold the pad from movement longitudinally of the supports a U-shaped locator stay 18 is adjustably mounted on each of the end supports 12 to engage the ends of the pad. The parallel arms 20 of the locator are provided with elongated slots 22 which embrace screws 24: mounted in the flange 12 of the end supports. The locator is preferably formed of sheet steel and pressed into shape. A downwardly projecting flange 26 is formed on the body of the locator, and when in position the flange is substantially normal to the face of the support 10, so that the entire face of the flange engages the end ofthe pad. In using the locators, the pad is preliminarily brought into position on the supports, then the flanges 26 are brought into engagement with the ends of the pad by adjusting the locator along the screws 24, and the screws set to lock the locator in its position.

With this construction, the locators 18 can be adjusted relatively to the support, and relatively to one another to place the pad in any desired position upon the support. The pads very often differ in length so that the locators must be adjusted to adapt themselves to the length of the pad. With this adjustment the pad also can be located in different positions on the support to place the bunches 28 of the pad in different positions longitudinally of the support. In removing the pad the screws 24E are loosened, and the pad will be free. With this method of locating the pad, the body portion is not pierced by screws or injured in any way, so that it will wear much longer and still it is firmly and accurately held in position.

Having thus described the invention, What is claimed as neW is:

l. A pressing form for sole laying machines having, in combination, a continuous pressing pad, a support for the pad having a flange at its sides to prevent transverse movement of the pad, and a rigid locating stay at each end of the support to engage the pad and hold it from longitudinal movement, one of said stays being movable to' permit removal or insertion of the pad.

2. A pressing form for sole laying machines having, in combination, a continuous pressing pad, a support for the padfhaving flanges at its sides to prevent transverse movement ofthe pad, and a locating stay on each end of the support to engage the ends of the pad and hold it from longitudinal movement, one of said stays being adjustable relatively to the support.

3. A pressing form for sole laying machines having, in combination, a continuous pressing pad, a series of movable supports for the pad having flanges at their sides to prevent transverse movement of the pad, and locating stays adjustably mounted on the tWo end supports to engage the ends of the pad and prevent longitudinal movement thereof.

4. A pressing form for sole laying machines having, n combination, a continuous pressing pad, a support for the pad having flanges at its sides to prevent transverse movement of the pad, and a locating stay at each end of the support to engage the ends of the pad and hold it from longitudinal movement, said stays being longitudinally adjustable of the support and havingv a` pad engaging face which is substantially normal to the face of the support.
