Patented Oct. 12, 1937 SOLE PRESSING PAD Chester D. Turner, Haverhill, Mass, assignor to United Shoe Machinery Corporation, Paterson, N. J.,, a corporationof New, Jersey 2 Application May 27, 1936, Serial No. 82,081

, 5 Claims.

This invention relates to, pads for pressing soles on shoes and particularly to covers for such pads.

Objects of the invention are to improve the operation and prolong the life of such pads.

As illustrated herein, the invention isembodied in a pad having a cover and means for holding the cover yieldingly in place upon the pad.

In the use of sole pressing pads such as that disclosed in Letters Patent of the United States No. 2,017,982, granted October 22, 1935, on an application of Frank Merritt, it has been found that after considerable use the rubber top surface of the pad becomes somewhat roughened and worn and the continued bending of the upper, portion of the pad adjacent to the slots which are formed in its lower surface, particularly, at the forepart of the toe, is apt to cause the rubber finally to give way. Pads of this type are frequently adjusted by raising or lowering the ball line portion with respect to the two ends of the pad and it is hence undesirable to reduce the flexibility of the pad by a cover secured tov it in'such a way as to interfere with its bending. Accordingly, the cover may, as illustrated, be composed of a plurality of layers of durable sheet material such as leather or of a single layer of suitable thickness, the cover being held in place on the pad by yielding means which, while keeping the cover in proper place upon the pad, permits unrestricted bending of the pad; Eyelets may be inserted about the periphery of the cover which not only serve to hold the layers of the cover together when it is made up of a'plurality of layers but also provide protected openings through which an elastic element such as a cord or tape may be passed to hold the cover in place upon the pad. The cord or tape between the openings may be secured in various ways to hold the cord yield ingly in place, for example by passing the tape or cord around under the pad from an eyelet on one side of the cover to an eyelet on the other side of the cover and so on, back and forth. 1

In the drawing,

Fig. 1 is a perspective view of a pad with the cover of the present invention applied thereto, and

Fig. 2 is a perspective view of the pad in inverted position, parts being shown in section.

The yieldingly held pad cover of the present invention, as shown in Fig. 1, comprises a piece of leather in cut approximately to the shape of a shoe sole and somewhat larger than the largest shoe to be operated upon. If desired, the layer Ill may be supplemented, as disclosed in Fig. 2,

by another layer of similar shape and-of the same or different material. Leather orpigskin have been found to be suitable materials from which to form the pad cover. Around thep'e'riph ery of the cover H) a series of eyelets [4 are inserted which serve as hollow rivets to hold the layers of the cover together when two or more layers are used and serve further to provide protected openings through which an elastic member It may be threaded to hold the cover I yieldingly in position upon a pad l8. The pad l8, as illustrated herein, is of the type disclosed in the patent previously mentioned andconsists of a central portion 20 of solid but comparatively soft rubber and a peripheral portion 22 of more rigid material which, at the forepart, is separated from the softer portion 20 by a slot 24,-and, in the vicinity of the ball line, the forepart and the shank part of the pad are separated by a slot 26. The slots extend from the lower surface of the pad toward but not to its upper surface, and the upper portion of the pad above the slots may be made of the same grade of material as the central portion of the pad and extend over the harder portion 22 to the edge of the pad. The entire shoe engaging surface of the pad is overlaid with a thin layer 28 of rubber softer and tougher than the portion 20, the layer 28 being vulcanized to the portion 20 to form an integral pad structure.

In adjusting the pad for shoes that are to have different heights of heels, the pad has tobe bent about a transverse axis in the vicinity of the ball line, which bending is facilitated by the slots 26, and it is important so to arrange the cover It] that it will not interfere with the adjustment of the pad. Accordingly, the cover I0 is attached to the pad by means of the elastic cord l6 which may be passed through the eyelets H5 at convenient points and secured to the pad or to the machine in which the pad is used in such a manner that the cover II] will be held in proper position upon the pad l4 and, by reason of such yielding connection, can accommodate itself to any changes in the longitudinal contour of the pad. Also, if desired, the resilient cord may be passed under or back of the pad from one side to the other and threaded through suitable eyelets to hold all portions of the cover extended over the shoe-receiving surface of the pad.

Having thus described my invention, what I claim as new and desire to' secure by Letters Patent of the United States is:

1. Apparatus for applying pressure to shoe soles comprising a yielding pad, a cover for the shoe-engaging surface of the pad, and resilient means extending from one side of the cover under the pad to the other side of the cover for holding the cover in operative position upon the pad while permitting the engaging surfaces of the pad and cover to shift relatively to each other.

2. Apparatus for applying pressure to shoe soles comprising a rubber pad, a leather cover for the shoe-engaging surface of the pad, and an elastic cord passing through holes in the margin of the cover and extending under the pad for holding the cover in operative position upon the pad.

3. Apparatus for pressing soles upon shoes comprising a yielding pad adapted to be bent about a transverse axis to adapt it for pressing soles upon shoes which are to have difierent heights of heels, a cover for the pad having protected openings about its periphery, and a resilient cord threaded through the openings and carried under tension back of the pad to hold the cover in operative position upon the sole-receiving surface of the pad.

4. Apparatus for pressing soles upon shoes comprising a yielding pad adapted to be bent about a transverse axis to adapt it for pressing soles upon shoes which are to have different heights of heels, a cover for the pad having protected openings about its periphery, and a resilient cord threaded through the openings and passed under tension back of the pad to the opposite side of the cover to hold the cover yieldingly in operative'position upon the sole-receiving surface of the pad.

5. Apparatus for pressing soles upon shoes comprising a rubber pad having a transverse slot in its lower portion whereby it is adaptedto be bent about a transverse axis to shape it for pressing soles upon shoes which are to have different heights of heels, a leather cover for the pad having a plurality of layers connected by eyelets about their peripheries, and a resilient cord threaded through the openings in one edge of the cover and passing under tension back of the pad and through an opening in the opposite edge of the cover to hold the cover in operative position upon the sole-receiving surface of the pad.
