UNITED ,STATES PATENT OFFICE REMOVABLE SKATE AND BLADE 7 Patrick Adonizio, Pittston, Pa. -.Applicati0n July 18, 1939, Serial No. 285,203 I 2 Claims. 01. 2s0--11.17)

One object of this invention is to provide an ice skate having a tread of novel form, and another With the above and other objects in view,

which will appear as the description proceeds, the invention resides in the, combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed,

without departing from the spirit of the inven tion. I

In the accompanying drawing:

Fig. 1 shows in side elevation, a device constructed in accordance with the invention;

Fig. 2 is a section on the line 2--2 of Fig. 1;

Fig. 3 is asection on the line 33 of Fig. 1;

Fig. 4 is a fragmental side elevation showing a modification;

Fig. 5 is a fragmental side elevation showing another modification.

The device forming thesubject matter of this application preferably is made of metal throughout. It includes a narrow blade I, forming part of a tread, which, as a whole, is marked by the letter T. A tubular reenforcing rail 2' is provided, and is supplied in its bottom with a slot, receiving a portion of the blade I, the blade I extending upwardly to the top of the rail .2. The rail 2 and the blade I are joined together by welding or otherwise. The structure as thus far described is of importance, in that it enables the blade I to be thin and have an unusually secure hold on the ice. The structure, moreover, saves material.

At its forward end, the blade I has an upwardly extended and forwardly curved nose 3.

The nose might be straight, as shown at 3a in Fig. 4. It might be straight as shown at 312 in Fig. 5, the blade Ib being prolonged in front of the nose 3b to form an extension 4, the reenforcing rail 2b being'extended well upon the nose 4, to stiffen it. Infits upper end, the nose 3 has an opening, illustrated sufficiently by the corresponding parts 5a and in Figs. 4 and 5,

. respectively.

The numeral 6 marks an article of footwear, such as a hockey shoe. The sole of the shoe i'has been indicated at I and is substantially coextensive in length with the, shoe 6, and forming part of the shoe. The sole I, may be the ordinary shoe sole, of leather of the like, if preferred.

To the sole 1, at the forward end thereof, is secured a metal reenforcing strip 8, which, preferably, is approximately coextensive in width with the sole or base I and is somewhat greater in length than half the length of the sole of the shoe 6. At its forward end, the strip 8 has a depending, forked stud 9, into which is inserted the upper end of the nose 3, the nose being connected to the stud removably, by asecuring element Ill, such as a nut and bolt. At its upper end, the stud 9 has a head II of liberal dimensions, making a firm and secure union between the stud and the strip 8.

The reenforcing rail 2 is received within and secured to a downwardly tapered rear post I 2, having a threaded cylindrical portion I4 merging into a smooth, reduced, cylindrical neck I5, the

post I2 preferably being hollow. The neck I5 is received within a collar .IB, carried by a rear strip I1, attached to the sole 1. The collar I6 is externally threaded. A threaded coupling ring It! is detachably engaged with the cylindrical portion I4 of the post I2 and withthe collar IE;

and abuts against the strip IT.

The post construction and associated parts are duplicated, as shown at I9, in connection. with a forward strip 8., V

The coupling rings I8 are threaded down on the cylindrical portions I4 of the posts I2, the necks I5 are inserted into the collars l6, and the coupling rings I8 are threaded upwardly upon the collars I6, to hold the parts assembled, as in Fig. 2. This operation lines up-the hole in the nose 3 with theholes in the stud 9, and the securing element II! is mounted in place.

The structure is simple, but it affords an. inexpensive and convenient meanswhereby one skate, or tread may be substituted in place of another, without detaching the base or sole I from the shoe 6.

Having thus described the invention, what is claimed is:

l. A- skate including a base plate having collars, a tread having posts provided with smooth upper ends received in the collars. and coupling plate being provided with a part wherewith the nose coacts, said part and the nose having registering openings, the openings being brought into registration when the rings are threaded on the collars, and a securing element detachably mounted in the registering openings.
