HARRY .T. LOZIER, OF DES MOINES, IOWA.

RUBBER-SECURING DE VICE.

have invented a new and useful Improvement in Rubber-Securing Devices, of which the following is a specification.

The object of my invention is to provide a device which may be secured to the inner portion of a rubber and will be adapted to grip the shoe, when the rubber is placed thereon and make it impossible for the rubber to pull off regardless of how sticky or adhesive the mud, through which the person may be walking, may be.

Another object is to provide such a device which will be adjustable so as to be made operative for any kind or style of a shoe.

A further object is to provide a device of this character which will not be bunglesome or unsightly but which will be practically hidden by the rubber, a very small portion thereof extending above.

A further object is to provide such a device in a simple, strong, durable and inexpensive construction, which may be sold independent of the rubber and is adapted to be secured in any rubber.

My invention consists of certain details of construction hereinafter set forth, pointed out in my claims and illustrated in the accompanying drawings in which Figure I shows a detail view of the gripping member I employ; Fig. II shows a detail view of my device, removed from a rubber, the gripping member being removed therefrom; Fig. III shows a front elevation view of my device complete but removed from a rubber; and, Fig. IV shows a side elevation view of a shoe incased by a rubber, shown inlongitudinal section, my device being secured in position.

Referring to the accompanying drawings the reference numeral is used to indicate a rubber of any ordinary type and the numeral 11 indicates the base of my device provided with orifices 12 by which it is secured through the heel of the rubber by any of the ordinary means, rivets and the like. At the rear of the base is an upwardly projecting portion 13, integral therewith and being constructed of spring metal. The length of this portion 13 is designed to be sufficient for it to extend from the base of i the rubber to a point slightly beyond the Specification of Letters Patent.

Application filed March 16, 190B.

Patented Nov. 3, 1908.

Serial No. 421,458.

the base and the upwardly projecting member is designed to be slightly less than the angle between the heel. and the back of the rubber, thus obviously causing the upwardly extending portion 13 to assume a position immediately inside the back of the rubber at its base and being separated at some little distance from the upper portion of the back of the rubber, thus obviously causing the tension of the spring metal of which the said upward portion 13 is composed to be against the back of the shoe so as to be adapted to grip the shoe with the gripping member as will be hereinafter explained. The said portion 13 is provided with a longitudinal centrally located slot 11 and in that part where the slot occurs the said portion 13 is wider, as shown in Figs. II and III, for the purpose of providing strength at that particular part of the lever, for such the upwardly extending member 13 is con sidered to be.

The numeral 15 indicates a lug beveled on its forward face so as to provide an acute angle 16 along its entire forward surface. Its rear surface being designed to engage the forward part of the lever 13, and centrally located in the rear portion of the lug 15 is a screw threaded shaft 17 designed to project. through the slot 14, and to be engaged by a nut 18 and in this manner the said lug, which is designed to construct the gripping member of my device, is secured to the lever 13. The said lug is also provided with, shoulders 19 and 20 designed to be engaged by their respective longitudinal sides of the lever 13, for the purpose of providing lateral bearings for the said lug and thus preventing it from binding. It is obvious that the lug 15 may be moved up or down upon the lever 13 and may be adjustably secured thereto. The shaft 17 is designed to be of a sufiicient length to extend through the slot 14 and to receive the nut 18, but no longer, so that the shaft will not project into the back of the rubber, when the rubber is on the shoe. The upper extremity of the upwardly projecting member 13 is turned, to the rear, as shown at 21, to provide a handle or thumb support, or the like.

In practical operation, my device being secured in the heel of a rubber the lug 15 is adjusted so that, when the shoe is in the rubher, it will be at the right height to engage the recess, which is in every shoe between the top of the heel and the soft leather part.

At this place the said lug 15 is secured and it is obvious that thereafter the said lug will not need resetting until the heel of the shoe is changed or a new pair of shoes used. It is obvious that as the tension of the spring lever 13 is toward the forward part of the rubber, that the heel being forced downwardly in the rubber will press the said member 13 to the rear and against the back of the rubber until the shoe is completely in the rubber, when the recess, before mentioned, between the up er part of the heel and the soft portion 0 the shoe will be in line with the gripping member 15, and obviously, will be gripped thereby. The said gripping member 15 is designed to be of a sufficient length so that it will project into the said recess when the shoe is in the rubber thus making allowance for different curves at the back of the shoe. In releasing the rubber the wearer inserts his finger or thumb between the turned portion 21 and the shoe and forces the lever 13 outwardly, and thus the gripping member is removed from its recess allowing the shoe to be withdrawn from the rubber.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is:

1. A rubber securing device comprising a base provided with orifices and an upwardly extending spring back, provided with a centrally located slot; a in provided on its rear surface with a screw tireaded shaft and a shoulder on each lateral side of said lug, said lug being beveled on its forward surface; a nut designed to en age the screw threaded shaft on said lug, su stantially as shown and described.

2. A rubber securing device comprising a base adapted to be secured to the bottom of the rubber; an upwardly projecting spring member provided with a longitudinal slot, said member being wider in its body portion directly opposite the said slot and being turned at its upper extremity; a lug beveled on its forward surface designed to be adjustably secured to said spring member; means for securing said lug to said spring, substantially as shown and described.
