H FRICTION-SHOE FOR SELF-PLAYING MUSICAL INSTRUMENTS.

T all whom it may concern:

Be it known that I, IRVING B. SMITH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Friction-Shoes for Self Playing Musical Instruments, of which the following is a specification.

This invention relates to improvements in what are known in the art as friction shoes for self-playing musical instruments. Such shoes are, as is well known, incorporated in the mechanism to be brought into contact with an element by which they are actuated to operate the instrument action. Heretofore the shoes have been constructed of wood provided with a sole or facing of cork, leather or other suitable material. In use the wear comes upon the sole or facing and when the same becomes worn to a degree that detracts from an accurate cooperative relation between the shoe and the actuating element therefor, the only remedy has been the removal of the shoe and substitution of a new one This is troublesome, both in the removal of the old and substitution of the new, and particularly in the latter operation, because the new shoe has to be adjusted with great nicety.

It is the object of my invention, in the first place, to provide a shoe constructed with separate foot portion which may be readily, accurately and securely attached to and detached from the body portion of the shoe, enabling a worn footto be taken out and a new one substituted with easeand facility.

In the second place the object of the invention is to improve the construction of the shoe in other respects as will hereinafter appear.

To the ends stated the invention consists of a shoe and its elements possessing the characteristics hereinafter described.

That which is regarded as new will be set forth in the claims appended to the description.

Referring to the drawings, wherein I have shown that which I regard as the best known embodiment of my invention,Figure 1 is a side elevation of the complete shoe Fig. 2 is a perspective of the body-portion of the shoe; F1g. 3 is a perspective of the foot-portion; Fig. 4 is a perspective of a spacer or filler element; and Fig. 5 is a perspective of a different type of body-portion.

In said drawing, the reference numeral 1 Specification of Letters Patent.

Application filed May 3, 1906.

Patented June 9, 1908.

Serial No. 315,059.-

designates the body-portion of the shoe and 2 the foot-portion. The body-portion is constructed with means for the connection of the removable foot-portion. Preferably this means consists of one element of a tongue and groove-connection, and as shown, the body portion is provided with the tongue element 3, 3. The foot-portion, in this eX- ample, is provided with grooves 4, 4, to take over the tongues 3, 3.

Means are provided to insure the accurate positioning of the foot-portion with relation to the body-portion, and a simple and preferable means is shown, consisting of a stop in the form of an offset or lug 5 with which the foot-portion is provided and which is so located that when in the act of assembling the body and foot-portions the stop comes against a complemental stop such as at 6 of the body-portion, the foot will be in exactly accurate position.

Releasable means are provided for retaining the body and foot-portions in assembled relation, which means may be of any suitable description. In Fig. 1, a screw 7 passing through the wall 6 and into the stop 5 is shown. In Fig. 5 the retaining means is automatically acting and consists of a spring finger S with which the body portion is rovided and the hook 9 of which takes bac of the stop 5. I/Vhen this type of means is used it will be observed the stop 5 is confined and held securely between the hook 8 and body.

wall 6. I contemplate, furthermore, providing a light, yet rigid shoe, of economical manufacture, a skeleton body portion of sheet metal. T 0 this end the said bodyportion is struck up from a sheet metal blank,

referably of steel or aluminum bronze, with lireast wall 6 and wings 10 of suitable shape, and with a base 11 to receive the foot portion, said base being fashioned to provide the tongues 3, 3. To hold the wings 10 rigidly in proper relation to each other a spacer or filler-block 12 is interposed between the same and may be secured in any suitable way, as by rivets 13. The body portion is provided with means, such as pivot openings 14, for the pin by which it is incorporated as an element of the playing mechanism. When the retaining means are of the kind illustrated in Fig. 5, the spring finger may be struck out from the wall 6 as shown. The foot portion 2 is preferably of wood, (maple is desirable) and is preferably provided with a standard sizes as articles of manufacture andmay be easily removed when worn and as easily, and with accuracy and without special skill, be replaced by a new one.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A friction-shoe for self-playing musical instruments consisting of a body-portion having a laterally projecting base, and a separable foot-portion detachably connected to said base and having a convex active face.

2. A friction-shoe for self-playing musical instruments consisting of a body-portion having a laterally proj ecting base, a separable foot having a convex active face, and a tongue and groove connection between said foot and base.

3. A friction-shoe for self-playing musical instruments consisting of a body-portion having means at its upper end for pivotally supporting the same, a separate foot portion having a convex active face provided with a facing of friction material, means for separably connecting said portions, means for accurately positioning said portions when assembled, and releasable means for maintaining the connection of said portions.

4. A friction shoe for self-playing musical instruments, consisting of a body portion, a separate foot portion slidably connected thereto and provided with a stop, and a convex active face and releasable means cooperating with said stop for maintaining the connection of said portions.

5. A friction shoe for self-playing musical instruments, consisting of a skeleton body portion constructed of sheet-metal, and provided with a laterally projecting base a foot portion separably connected to i said base, and having a convex active face and releasable means for maintaining such connection.

6. A friction shoe for self-playing musical instruments consisting of a skeleton bodyportion constructed of sheet-metal having breast wall, parallel wings and base-portions, a foot portion having a convex active face separably connected thereto, and releasable means for maintaining the connection.

7. The friction-shoe body constructed of sheet-meta] having breast wall and parallel wing-portions, and a forwardly extending base portion provided with means for connection to a shoe foot.

8. The body 1, constructed of sheet-metal having the breast wall 6, parallel wings 10, forwardly extending base 11, and filler 12 between said wings.

9. A friction-shoe foot of the character described having its opposite faces respectively flat and convex and provided on opposite sides with means for connection with a shoebody.

10. The friction-shoe foot having its opposite faces respectively flat and convex and a stop rising from said flat face.

11. The friction-shoe foot having its oppo site faces respectively fiat and convex, a stop rising from said flat face, and means on opposite sides of the foot for connection with a shoe-body.

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

IRVING B. SMITH.
