SHOE TBEAD.

Application filed October 1, 1921. Serial No. 504,570.

To all whom it may concern Be it known that l, Jenn E. Masriins, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented new and useful Improvements in Shoe Treads, of which the following is a specification.

This invention relates to improvements in shoe treads.

It is a well known fact that the treads of shoes generally wear at some particular location thereon much more than at others, and inrepairing said shoes it is necessary, especially in the case of rubber heels, to throw away the entire heel when only a small portion thereof has actually been used. The result is a waste of much valuable material, while the fact that the shoes must be repaired involves considerable expense and inconvenience on account of the necessary delay that usually occurs while the repairs are being consummated.

The object of the invention is to provide the tread. portion of a shoe, and particularly the heel thereof, with removable cushions which, upon becoming worn, may either be replaced at small expense by new cushions, or said cushions may be interchanged in a manner to distribute the wear so that a greater portion of the material of which they are constructed maybe utilized.

Another object of the invention is to pro vide a simple structure in which the cushions may be inserted and removed at will. when replacements are necessary and which may be easily attached to and detached from the body of the heel by the wearer without requiring the services of a professional shoe maker, and thereby avoidinginconveniences and delay.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings:

Figure 1 represents a top plan view of a heel embodying my invention.

Fig. 2 is a vertical section taken on the line 2-2 of 1.

Fig. 3 is an underneath plan view f the heel.

Fig. 4 is an end'elevation of a portion of the heel as taken on the line ll of Fig. 1, the end plate having been removed.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5 represents the main body portion of a heel which may be con struoted of any suitable relatively hard material, as, for example, metal, wood, leather, hard rubber or any of the manufactured materials resembling rubber and embodying the properties thereof. The main body portion 5 of the heel may be secured to the main body portion of a shoe by nails which pass through holes 6, or in any other manner well known to those skilled in the art. A metal plate 7 provided with a beveled edge 8 is located in a recess 9 provided in the under surface of the body 5 in which it is inserted from the front edge thereof, and when said plate is in position within said body, the beveled edge 8 thereof engages a correspondingly beveled portion 10 provided upon said heel. The plate 7 is provided with a plurality of similar openings 11 formed therein in which are mounted removable cushions 12. A plurality of other openings 13 also similar are also provided in the plate '7 in which removable cushions 1d are mounted. The cushions 12 and 14- are preferably constructed of rubber or any other suitable resilient material embodying the properties of rubber, or if especially hard usage is anticipateththeymay be constructed of a suitable metal, and may be provided with a suitable anti-slipping tread surface for use winter when the ground is covered with ice. The cushions 12 and let are beveled at 15 to fit correspondingly beveled edges of the openings 11 and 13 respectively and are inserted within said openings from the upperside of the plate 7 when said plate is removed from the body 5 of the heel. The cushions 12 are interchangeable with each other as are also the cushions 14.

The plate 7 is held in position within the recess 9 by a locking member 16 slidably mounted in a recess 17 located at the front of the body 5 of the heel and a spring 18 also located in said recess 17 normally holds said member in the position illustrated in Figures 2 and l, said members resting in a recess 19 formed in the plate 7 and projecting in front of a shoulder 20 formed upon said plate 7 by said recess 19. An end plate 21 secured to the body portion of the heel in any desired manner holds the locking member 16 in position within the recess 17.

If, when the user of a heel constructed as herewith illustrated and described, walks in such a manner that a greater portion of the wear falls upon but one of the cushions 12, said cushion may be interchanged and the worn cushion replaced by the cushion which is only slightly worn, or if the rear portion only of both of the cushions 12 have become worn while the forward portion of said cushions has only been slightly worn, said cushions may be interchanged and the portion of each member which formerly constituted the forward portion is then located at the rear. In like manner if one of the cushions 14: becomes partly worn at one side thereof while the other cushion 141.- is only slightly worn, the badly worn cushion 14 may either be removed and reinserted to present the inner portion thereof at the side of the heel, or said cushions may be interchanged. In this manner it is seen that a greater portion of each cushion may eventually be utilized before it is necessary to entirely, discard a cushion and replace the same with anew one, and it may be possible to replace the cushions 12 several times before it is necessary to replace the cushions 14:. The replacing of the cushions may easily be accomplished by the wearer by simply forcing the locking member 1.6 upwardly from in front of the shoulder 20 of the plate '7 and then sliding said plate forwardly out of the recess 9. The cushions are then removed by forcing them upwardly out of their respective openings and others are inserted in their places as required. t is evident that any form'of spring maybe employedin place of the spring 18 if it is so desired. It is also evident that any number of cushions may be employed and said cushions may be of any size and of any shape desired as they may be provided with circular, rectangular, triangular or diamond shaped tread surfaces without departing from the spirit of this invention. It is also evident that the sole portion of a shoe may also be provided with a tread surface embodying the features of this invention, the same falling within the scope of the appended claims.

I claim:

1. A shoe tread comprising a .main body portion, a plate havin sliding engagement with said body portion, a plurality of removable cushions mounted within said plate and a locking member slidably mounted in said body portion and engaging said plate to prevent the removal of the latter from said body portion.

2. a shoe tread comprising a main body portion, a plate having sliding engagement with said body portion and provided with a recess formed therein, a plurality of removable cushions mounted. within said plate and a locking member slidably mounted in said body portion and projecting into the recess in said plate to prevent tie removal of the latter from said body portion.

3. A shoe tread comprisinga main body portion, a plate adapted to slide into interlocking engagement with said body portion, said plate being provided with a plurality of openings formed therein having beveled edges, a plurality of interchangeable cushions provided with beveled portions adapted to fit said openings and a locking member slidably mounted in said body portion and engaging said plate to prevent the removal of the latter from said body portion.

i. A shoe tread comprising a main body portion, a plate adapted to slide into interlocking engagement with said body portion, said plate being provided with a plurality of openings formed therein having beveled edges, said plate also being provided with a recess formed therein, a plurality of interchangeable cushions provided with beveled portions adapted to fit said openings, a locking member slidably mounted insaid body portion and a spring adapted to force said locking member into the recess in said plate and thereby prevent the removal of said plate from said body portion.

In testimony whereof I havehereunto set my hand in presence of two subscribing witnesses.

JOHN E. MASTERS.
