Description As seen in the drawings and referring more particularly to Figures 1 to 11 inclusive, I have shown the bottom of a shoe l5 having a heel l6 and sole H, the construction of which may be of the usual type such as used by playersin various fields of sports, for instance, runners, football players, baseball players and so forth, who at times find it very inconvenient and injurious to keep Wearing their shoes with spikes and/or the like when not actually engaged in 5 the game or competition. Heretofore users of spiked shoes have had to change their shoes or walk on the spikes. According to the present invention it will not be necessary for a wearer to remove the spiked shoes when not engaged in competition, but insmad the user keeps the shoes on and may easily remove the spikes and/ or the like at will therefrom. Furthermore, according to my invention I can provide a shoe with spikes selectively upon the ball of the foot, the heel or both, securely retained in place to heel and sole plates in the shoe 15.

In carrying out the present invention, I provide a metal attaching plate l8 to remain a part of the shoe l5 with the body portion of said plate preferably having the shape of a standard spike plate 19 and embedded flush with the bottom of the shoe. Entirely embedded within the bottom of the shoe is another plate 20, for convenience referred to as a base plate, and which is preferably fiat. Rivets 2| or other suitable means applied at the corners of the attaching plate 18 will secure the two plates permanently assembled. The body portion of attaching plate 18, however, is offset from the base plate 20, this being conveniently accomplished by offsetting each corner 22 of the attaching plate. The outer ply, sole or lift of the shoe bottom is provided with an opening shaped to fit around the body portion of the attaching plate and overlie the offset portions thereof and the edge portions of the base plate. After this assembly of plates is applied to said ply, sole or lift, stitching or otherwise securing the ply, sole or lift makes the'plates a permanent and solid part of the shoe but without protruding from the bottom. This operation will assure at all times a permanent fixture of the plates I8 and 20 either to the sole I! or heel 16 of the shoe I5. In passing it is to be noted that the base plate 20 in shape is substantially the same as that of the sole portion of the shoe, though somewhat smaller in contour so as not to interfere with the stitching operation when the ply, sole or lift is stitched or otherwise attached to the welt of the shoe. I have found it very advantageous to utilize the base plate 20 in connection with the present invention for several reasons, one of said reasons and a particular feature being that it will prevent concentrated pressure of the spikes, when worn, bearing against the underside of a persons foot.

By virtue of the off-set mounting of the body of attaching plate I8 and base plate 20, a hollow space or recess 24 is provided, the purpose of V which will hereinafter be more fully described.

The attaching plate .I8 is conveniently provided with a plurality of openings therethrough,

said openings preferably being in the form of open-ended or key-slots 25, one of which is adjacent the forward end of the base plate and two others toward the rear of the plate, all substantially directed longitudinally of the shoe with their larger or open ends similarly placed with respect to each other. equally spaced from the toe and symmetrically disposed with respect to a medial line longitudinally of the sole, and between them is provided an opening 26 which likewise penetrates the thickness of the attaching plate I8.

Centrally of the plate I8 and in line with the opening 26 and the one key-slot 25 adjacent the forward end of the plateis a rivet 21 passing therethrough from the inner side of the plate,

and adjacent the underside of the base plate 20. Said rivet 2'l securely holdsa member 28 in placeto the inner surface of the plate I8, said member being of relatively thin spring metal and normally juxtaposed against the inner surface of said plate, and preferably having an area sufficient to underlie and close all said openings 25 and opening 26, thereby preventing dirt or other foreign substance from entering through these holes to fill the recess 24 between the base plate 20 and attaching plate I8, when the spike plate I9 is unattached therefrom.

The spike plate I9 may be providedwith a plurality of headed studs 29 the shanks of which project upwardly substantially the thickness of metal comprising the attaching plate I8, enabling the shanks to pass through slots 25 and the underside of the headed portions of studs 29 to engage the plate I8 for securely holding the spike plate I9 thereto. Said spike plate is applied in such manner that the headed studs are inserted first into the rounded or enlarged openings of the slotted openings or key-slots 25, and upon engaging the underside of the metal spring 28, the studs how the spring, after which the shanks register with the smaller parts of the slots 25 and then being pushed forwardly towards the forward end of the plate I8 or until the shanks of studs 29 have reached their limit of movement in the smaller ends of the slots.

To securely lock the spike plate I9 to the attaching plate I8 and prevent accidental removal of the spike plate I9 therefrom, I have provided on the underside of the said plate I9,

a means which in practice engages with the,

opening 26 in the plate I8. Such means may conveniently be an "elongated arm or flat spring member 30 and mounted at one end to the plate, as towards the forward part thereof by a rivet 3I. Adjacent the end opposite from the rivet end is a detent'32 which for convenience protrudes upwardly and away from the spring arm 30 but is securely attached to the spring arm by being welded or otherwise held thereto. When spike plate l9 has been slid home upon attaching plate I8, that is, after the headed studs 29 have been inserted in and moved to the smaller ends of slots 25, detent 32 will then register with and enter opening 26 thereby preventing any possible dislodgment of the spike plate I9 from the plate I8. When desiring to remove Two of these slots are the spike plate from the plate I8, the spring arm snaps down against and closes the several open- 7 mgs 25 and 26.

It has been found that the usual construction of spikes depending from spike plates of the prior art often bend or break when coming in contact with an obstruction in the ground, such as a stone, thereby rendering further service of the plate worthless. In the present invention, I have provided the spikes 33 depending from plate I9 of a durable and sturdy construction both by utilization of tempered steel and. by arching or reinforcing the same at the bends as at 34 and clearly appearing in section of Figure 10. Said arching may be accomplished by utilization of a power press (not shown) in punching or stamping a portion of the material. From the foregoing it will be readily understood that the strength of the spikes 33 are materially enhanced and the ability thereof to withstand wear and tear will be increased.

It further is to be understood, owing to the construction of the spike plate I9, that it will not be necessary to designate rights and lefts since the structure shown enables the removable spike plate to be used for either the right or left shoe. Furthermore, should a spike become damaged, the user can remove the damaged plate and apply a new one without removing or changing his shoe.

Referring now more particularly to Figure 11, I have shown a slightly different construction of attaching plate I8 and different manner in which it may be made fast with respect to the base plate 20. In this respect, I have illustrated the attaching plate I8 as being flat, and in order to provide for the recess 24 as heretofore described, I have provided washers 35 (three in number) one at each corner, and means asso-,

ciated therewith for making said attaching plate with interposed washers fast to the base plate 20. One such means comprises rivets 36 passing through from the insole of the shoe and terminating at the outer surface of the attaching plate I8.

This construction permanently holds the immovable members together and to the shoe, assuring against wobbling or displacement. It is to be understood that in securing the aforementioned members to the shoe, the sole or heel are not affixed thereto until after the members are first set. The spike plate I9 with headed-studs 29 and stud 32 may be applied to the attaching plate I8 as heretofore described in detail.

I have shown a further modification of attaching plate and spike plate in Figures 12 to 14 inclusive. In this instance an attaching plate 31 may be secured to the under surface of either to the heel I6 or sole II of the shoe I5 by flathead screws 38 countersunk in theplate so as not to interfere with attaching or removing spike plate 39 therefrom. Said plate 31 in this instance may be constructed so as to provide overhanging longitudinal shoulders 40 at its two side edges as seen in Figure 14. V

The spike plate 39 may be constructed as heretofore providing spikes 4|, but having its longitudinal side edges turned up and bent inwardly to provide grooves 42. Said grooves will engage the shoulders 40 when the spike plate 39 is slid home upon attaching plate 31. In order to lock the spike plate 39 to the attaching plate 31 so as to prevent accidental displacement, I have shown an elongated spring arm 43 pivotally mounted, as at 44, to the underside of the spike plate 39, free to move in a lateral direction when lifted at its free end. Said arm 43 adjacent its free end, that is, its end opposite to the pivoted end, is bent inwardly in the shape of a detent 45 and is adapted to pass through a slot 46 in the spike plate 39 and thence into a similar opening 41 in the attaching plate 39. In this condition the spike plate is prevented from sliding and is therefore held Securely to the plate 31 and cannot be removed until the spring arm with the detent is released from the opening 41. When the detent is lifted clear of the said opening 41, the arm may be then swung laterally into a position illustrated by the dotted lines in Figure 12, whereupon the spike plate 39 may be easily slid outwardly towards the forward end of the shoe l5 and removed.
