ATTACHING SOCKET FOR SHOE CLEATS Filed 001;. 9, 1935 H- D- .DrzLs'c all.

Patented Nov. 3, 1936 UNITED STATES PATENT OFFICE 8 Claims.

This invention relates to attaching sockets for shoe cleats of that general class shown and. described in United States Letters Patent issued to me on the 3rd day of December, 1935 under N0.

2,022,655, the present invention being an improvement thereon.

The object of the invention is to provide a shoe sole socket of simple and inexpensive construction capable of being readily attached to the outer lift of a shoe sole, either during the manufacture of the shoe or subsequent thereto and which will provide a secure anchorage for the opposite ends of a shoe cleat and effectually prevent accidental displacement of said shoe cleat when Walking, playing golf, or under other conditions of service.

A further object of the invention is to provide a shoe sole socket, the construction of which is such as positively to clamp the opposite faces of 6 the outer shoe lift and thus prevent the socket from working loose or being forced upwardly and embedded within the adjacent surface of the inner shoe lift.

A further object is to provide a shoe sole socket including a face plate having a recess formed therein communicating with a slot or socket in the shoe sole and provided with spaced attaching spurs adapted to extend through the socket or slot and engage the grooved face of a clamping plate.

i A further object is to form the opposite walls of the slot or socket in the shoe sole with flat faces against which the attaching spurs bear so as to prevent accidental rotation of the face plate.

A still further object of the invention is generally to improve the construction of the socket whereby the use of attaching nails, screws and similar fastening devices is entirely dispensed with. In the accompanying drawing forming a part of this specification and in which similar numerals of reference indicate corresponding parts in all the figures of the drawing,-

' Figure 1 is a bottom plan view of a shoe provided with an attaching socket constructed in accordance with the present invention, the cleat or anti-skid tread surface being indicated in dot and dash lines.

Figure 2 is a vertical sectional view taken on the line 2-2 of Figure 1.

L Figure 3 is a transverse sectional view taken on the line 3-3 of Figure 1.

' Figure 4 is a detail top plan view looking at the. inner face of the outer lift and showing how the terminals of the attaching spurs engage the clamping plate.

Figure 5 is a group perspective view with the parts comprising the socket separated.

Figure 6 is a group perspective view illustrating a modified form of the invention.

The improved shoe sole socket forming the subject-matter of the present invention is principally designed for detachably securing a shoe cleat or other anti-skid tread surface in position on the outer lift of the sole of a shoe, and by way of illustration is shown in connection with a shoe of conventional construction, in which 5 designates the upper, 6 the outer sole or lift, and I the inner sole, the cleat or anti-skid tread surface being indicated in dot and dash lines at 8. The cleat 8 is of the construction shown in my patent previously referred to and embodies a plurality of pivotally connected links, there being a headed pin 9 secured to each end of the cleat and coacting with a shoe sole socket for detachably securing the cleat in position on the shoe.

The shoe sole socket comprises an outer face plate I0 formed of metal or other suitable material and preferably circular in shape, as shown, the central portion of the face plate being provided with a substantially elliptical-shaped opening I I which communicates with a slot or socket I2 formed in the outer lift 6 of the shoe. The slot or socket I2 extends entirely through the outer shoe lift 6 and the width of said slot or socket is preferably less than the diameter of the face plate I0 so that when the face plate is positioned on the outer surface of the lift 6, said face plate will entirely cover the socket, as best shown in Figure 2 of the drawing. Secured to or formed integral with the face plate ID are upstanding attaching spurs I3 adapted to extend through the slot or socket I2 for engagement with an inner or clamping plate I4. It will here be noted that the slot I2 is narrower at its ends than at the center thereof and that the end walls at the narrow portion are flat or straight but of approximately the same width as the attaching spurs to form shoulders or abutments I5 for engagement with said spurs so that when the face plate is positioned on the shoe sole, the spurs I3, by engagement with said fiat walls or abutments, will prevent accidental rotation of said face plate. The inner or clamping plate I4 is preferably in the form of a flat metal disc of a diameter equal to or approximately equal to that of the face plate In and at opposite sides of the disc or clamping plate I4 the metal is cut away to form locking notches I5 adapted to receive the adjacent ends of the attaching spurs [3. The metal constituting the disc I4 is stamped or otherwise depressed between the locking notches to form a transverse seating groove I6 adapted to receive the pointed terminals ll of the attaching spurs so that when said attaching spurs are bent laterally they will seat within the groove 16 and thus present a perfectly fiat flush surface for contact with the adjacent surface of the inner sole or lift 1, as best shown in Figure 2 of the drawing.

In applying the improved socket to a shoe sole, the outer sole or lift is stamped, punched, or otherwise formed with the slot or socket l 2, after which the face plate I is positioned on the outer surface of the lift 6 with the attaching spurs I3 extending through the slot I 2 and in engagement with the fiat walls or abutments l thereof. The clamping plate l4 having been previously positioned on the inner face of the lift 6, the terminals of the attaching spurs are bent downwardly within the seating groove l6 thereby firmly clamping the parts together and preventing accidental displacement of the device. It is preferred to slightly moisten the leather of which the lift 6 is formed prior to the application of the socket thereto as by doing so the face plate and clamping plate will automatically seat themselves in the soft leather so that said plates will be disposed substantially flush with the respective faces of the shoe lift. It will thus be seen that the walls or abutments I 5 of the slot or socket l2 serve to prevent accidental rotation of the face plate while the attaching spurs l3 by engagement with the clamping plate I4 serve to securely clamp the device in position on the shoe sole. As the device is positively clamped on the shoe sole, it follows that liability of the face plate being forced upwardly or causing the clamping plate to become embedded in the inner sole is prevented and such movement is further prevented owing to the broad bearing surface the clamping plate presents to the inner sole.

In applying the cleat to the socket it is merely necessary to turn the cleat at right angles to shoe until the headed pin 9 of the cleat registers with the recess H in the face plate when the head will readily pass through the recess ll into the socket I2. By then giving the cleat a quarter turn, that is to say, moving the cleat to the position shown in Figure l of the drawing, the headed pin 9 will engage the walls of the face plate around the recess H therein and detachably hold the cleat in position on a shoe sole, as set forth in my prior patent.

While it is preferred to make the slot or socket l2 of the shape shown in Figure 5 of the drawing, it will, of course, be understood that this slot or socket may be of any other desired configuration so long as the flat end walls or abutments I5 are present and the slot or socket is of less width than the diameter of the face plate so that the face plate when positioned on the shoe sole will extend beyond the walls of the socket. A shoe socket constructed in accordance with the present invention may be applied with equally good results to a shoe sole during the manufacture of the shoe or when half soling a shoe without the employment of nails, screws and similar fastening devices, the stitching used for securing the outer lift of the sole to the inner lift serving to hold the clamping plate against the inner sole, as will be readily understood. It will, furthermore, be noted that the plate or disc l4 not only forms a clamping memher but also constitutes a closure for the inner end of the slot or socket 12, so as to prevent moisture, dirt and foreign matter which might possibly enter the socket through the opening in the face plate when the cleat is removed, from finding lodgment between the inner and outer lifts of the shoe sole.

In Figure 6 of the drawing, I have shown the face plate provided with three attaching spurs l3 which fit in countersunk seats I8 extending inwardly from the circumferential edge of the clamping plate. It will, of course, be understood that any desired number of such spurs may be employed and that said spurs may be of any desired Width and the terminals thereof pointed or blunt as desired without departing from the spirit of the invention.
