i type adapted to be removably attached to the sole of a shoe for affording a sure footing for pedestrians, athletes, and such persons, and the invention has for one of its objects to improve and simplify the construction of devices of this character so as to be comparatively simple and inexpensive to manufacture, reliable and eiiicient in use, and readily applied or detached.

Another object of the invention is the provision of an improved calk-carrying plate having sole-engaging hooks whereby the creeper is carried entirely by the sole, one of the hooks being movable and operated by a clamping lever to clamp or unclamp the plate on the sole.

\Vith these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate certain embodiments of the invention, Figure 1 is a bottom plan view of the creeper applied to a shoe. Fig. 2 is a perspective View of the creeper removed. Fig. 3 is a side View thereof. Fig. 4 is a transverse section on line 44, Fig. 2. Fig. 5 is a bottom plan View of a modified form of creeper intended more especially for icy surfaces. Fig. 6 is a top plan view of the creeper. Fig. 7 is a sectional view on line 77, Fig. 6.

Similar reference characters are employed to designate corresponding parts throughout the views.

Referring to the drawings, A designates the plate of the creeper, which is preferably a sheet metal punching of suitable gage and formed with a front calk 1 and side calks 2 and 3, adjacent the rear of the plate, said calks being in the form of lugs bent substantially at right angles to the plane of the plate and having their flat faces disposed in angular relation so as to prevent slipping in different directions. It is preferable to Specification of Letters Patent.

to be too heavy for the user, and in order to stiffen the calks, the metal at the point of bend is indented at 4 so as to form bracing ribs between the inner faces of the calks and plate, the bending of the calks and forming of the bracing ribs 4 being preferably done when the steel is soft and afterward, the plate is tempered. At the front corners of the plate A are upwardly-extending and oppositely-curved sole-engaging hooks 5, and projecting from the rear por tion of the plate is a laterally-curved arm 6 terminating in a sole-engaging hook 7 disposed behind the calk 3 and arranged to engage the sole B of theshoe at the curved portion where the sole merges into the shank.

The plate is provided with a second arm 8 disposed approximately at right angles to the arm 6 and extending rearwardly and to the opposite side of the sole. This arm 8 carries a movable sole-engaging hook 9 that is disposed to grip the sole at the portion thereof where the same curves inwardly to merge into the shank, the front hooks 5 being disposed to grip the sole close to the toe portion thereof so that four points of engagement are provided between the creeper and shoe sole, whereby the creeper is firmly held in place. The calks 2 and 3 are arranged between the front side hooks 5 and the rear hooks 7 and 9. In order to lighten the weight, the central portion of the plate A is cut away at 10 and the arm 8 is depressed out of the plane, as at 11, of the plate, so as to be offset from the bottom face of the sole in order to accommodate the slidable hook 9 and the means for operating the same. The hook 9 has a base portion. 12 provided with a longitudinal slot 13 through which extends a headed rivet 14E fastened to the arm 8, and the arm 8 itself has a longitudinal slot 15 in which engages a pin or projection 16 on the base 12 of the hook 9 whereby the pin and rivet co oper'ate to guide the hook inwardly and outwardly during the operation of clamping or unclamping the creeper. At the inner end or root of the arm 8 is pivoted an operating lever 17 that is connected by a link 18 with the sliding hook 9. The lever is attached to the plate A by a rivet 19, and the link is connected by a pivot 20 to the lever and to the sliding hook 9 by the guide pin 16 that forms a pivot. The link 18 is in the form construct the plate of light steel so as not gripping the sole.

of a flat spring and is provided with spaced apertures 21 for engagement with the pin 16 to thus permit the sliding hook-16 to be adjusted inwardly or outwardly to accommodate the clamp to soles of different sizes, and the resiliency of the link will hold'the same engaged with the pin 16 without the need of any fastening, so that a ready adjustment of the link is always afforded. \Vhen the creeper is applied to the sole, the link, the inner portion of the lever and the base of the sliding hook, are housed between the bottom of the sole and the offset portion or arm 8 of the plate, so that the parts are protected from injury. The lever 17 which is resilient, has its outer end formed into an upstanding lug 28 so arranged as to engage the side edge of the sole immediately adj acent the sole-engaging hook 7, and when the creeper is fully clamped, the lever 17 will bear against the arm 6 that forms a stop for the lever.

In applying the creeper to the sole, the lever is swung close to the arm 8 of the plate A so as to thereby move the sliding solegripping member outwardly to its full extent. The creeper is then adjusted to the sole in such a manner as to grip the hooks .5 and 7 to the edges of the sole, as shown, and the lever 17 is then thrown in the opposite direction to move the hook 9 inwardly for As soon as the free end of the lever, which rides on the bottom surface of the sole during the clamping move ment, reaches the edge of the sole, it springs upwardly so that it will lie in the same plane as the arm 6 of the plate. The arm 6 prevents the lever from being moved too far, while the lug 23 on the extremity of the lever engages the sole so as to prevent the lever from opening. The lug 23 may be provided with an aperture 2% for engagement with any suitable instrument, if found necessary, for unclamping the creeper. In unclamping the creeper, the lever is first sprung downwardly out of the plane of the arm 6 so as to withdraw the lug 23 from the sole to ride over the latter during the opening movement of the lever. This opening movement projects the clamping hook 9 away from the sole so as to permit the fixed hooks 5 and 7 to be disengaged. The creeper, above described, is especially adapted for baseball players, runners and other athletes, although it can be used as an ice creeper, if desired.

The preferred form of the invention, as adapted for an ice creeper, is disclosed in Figs. 5 to 7, inclusive, in which the plate A is provided with groups of calks in the form of pointed spurs 25 depei'iding from the bottom side of the plate. The plate is provided with the front hooks 5 and a rear hook 7. The rear part of the plate is offset at 26 out of the plane of the plate for accommodating the sliding hook 9', operating lever 17, and link 18. The operation of this form of creeper is substantially the same as that al ready described, so that further description is deemed unnecessary.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.

Having thus described the invention, what I claim as new, and desire to secure by Letters-Patent, is
