Specification of Letters Patent.

Patented June 22, 1%15.

Application filed April 19, 1915. Serial No. 22,458.

To all whom it may concern Be it known that we, NATHAN GENn'rHo TULLER and ANDREW MATlI-IE\V RASMUSSEN, citizens of the United States, residing at Beloit, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Ice-Skates, of which the following is a specification, reference be ing had to the accompanying drawings.

Our present invention relates to new and useful improvements in ice skates and as its principal object aims to provide a skate in which the sole plate is yieldably supported. on the runner by a novel form of shock absorbing support.

Another object is to construct a shock absorbing supporting member, which is designed with such regard to proportion, number and arrangement of parts, that it may be cheaply manufactured, will be durable and efficient in service and may be readily applied to or removed from the skate, without requiring any extended changes or alterations in the construction thereof.

A. further and more specific object of the invention is to provide a support which is particularly adapted for application to the rear end of the sole plate and consists essentially of a pair of telescoping members, between which is interposed a helical spring adapted to absorb, to a considerable extent, all the shock and impact ordinarily transmitted from the runner to the sole plate, as a result of contact of the runner with rough ice or when the skater is jumping, hurdling or performing some similar feat.

The above, and other incidental objects of a similar nature, which will be hereinafter more specifically treated are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claim which is appended hereto and forms part of this application.

With reference to the drawings, wherein there has been illustrated the preferred embodiment of this invention, as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts.

Figure l is a side elevation of the skate; Fig. 2 is a vertical section taken through the shock absorbing member; Fig. 3 is a top plan view of the sleeve of the supporting member; and Fig. lis a detail perspective view of the stud of the supporting member.

As disclosed particularly in Fig. l of the accompanying drawings, the supporting member designated, as an entirety by the letter A is especially designed for application to the sole plate B of the skate at the rear termlnal thereof. It will, of course, be understood, however, that the member A may be employed in connection with the tip of the sole plate or as a supporting member for the heel plate, without departing in any way from the spirit of the invention.

The supporting member A. consists essentially in three elements, a tubular sleeve 10, a stud or stem 11 and a helical spring 12 which is disposed within the sleeve and normally tends to project the stud from the sleeve. 6

The sleeve 10 is, as stated, preferably tubular in shape, although it may be polygonal, if so desired. The upper end of the sleeve is closed by a circular head plate 13 which is of greater diameter than the sleeve and is provided adjacent its perimeter with a plurality of threaded bores 14. Fastening screws indicated at 15, are passed through receiving apertures 16 formed in the sole plate B adjacent the rear end thereof for threaded engagement in the bores of the head plate, for the obvious purpose of rigidly attaching the sleeve to the sole plate. The sleeve 10 is of a length less than the distance normally included between the sole plate and the upper edge of the runner 17 when the sole plate is in parallel relation thereto. The stud or stem 11 is bifurcated at its lower terminal, as indicated at 18 to produce the parallel lugs 19. As shown in Fig. 2 the lugs are engaged against opposite faces of the runner when the stem is applied thereto. The upper end of the stem is cored out to form a socket 20, in which the lower end of the spring 12 is seated. The upper end of the spring 12, of course, bears against the head plate. The spring, when not under compression, tends to hold the stud partly projected from the sleeve as in Fig. 2.

From the foregoing description, it will now be seen that the supporting member A serves as a shock absorbing element which will take up any impact or jars to which the runner of the skate is subjected. It will also be seen that inasmuch as the supporting member A is extensible, the sole plate is yieldably supported at its rear end so that it may readily conform to the surface of the shoe sole of the skater.

In reduction to practice, it has been found that the form of this invention illustrated in the drawings and referred to in the above description as the preferred embodiment, is the most eflicient and practical; yet realizing that the conditions concurrent With the adoption of this device will necessarily vary, it is desirable to emphasize the fact that variousminor changes in the details of construction, proportion and arrangement of parts may be resorted to,-When required, without sacrificing any of the advantages of this invention, as'defined by the appended claim. I

What is claimed is The combination With a skate, of a shock absorbing supporting member for the sole plate thereof, said supporting member including a stud having its lower terminal bifurcated to receive the skate runner and having a socket formed in its upper terminal, a sleeve slidably receiving the stud, a head plate formed on the sleeve, fastening devices detachably securing the head plate to the plate.

In testimony whereof We hereunto al'lix our signatures in the presence of two Witnesses.
