To all about it may concern:

lie it known'that 1,1. HUNTER HAR- woon, ot' the city of Detroit, State of Michigan, have invented a Convertible Skate, oi. which the following is a specification.

The object of my invention is to construct a skate which may be used on the ice and on a iioor or pavement alterni'ttely by making it interchangeable from a roller-skate to an iceskate, the rollers and the skate-iron being in ude adjustable and removable upon the same frame for that purpose, as hereinafter more fully described.

1n the accompanyin drawings, Figure 1 is a side view of a roller-skate, showing my im- Fig. 2 is a side view, represent ing my improved skate with iron runner attached in lieu ot't erollers. Fig. 3 is acrosssection of skate-stock, with end elevation of roller attachment. Ii 4: is a cross-section of skatestock, with end elevation of iron blade attached; Fig. 5 is a bottom-plan view of beveled dovetail seat. Fig. 6 is a perspective view of Fig. 2, and Fig. 'I a perspective view or" an adjustable roller-frame.

The same letters refer to like parts in each of the figures.

A I) represent a metal socket or slide, which is composed of the bed'plate A and two projecting bars, I, the adjacent inner surfaces of which are made in dovetail shape, and slightly divergent from one end to the other, thus forming a key-scat for the reception of the wedge-block d, hereinafter described. This seat is securely fastened to the frame or stock of the skate by means of two or more lugs, c, which project from the bed-plate A, and by screws introduced through them into the body of the frame. If the stock or frame of the such manner that it may be passed lon gitudi- '1 nally into it from one end of the seat until it is securely driven home, and thus firmly and rigidly held between the bars 1;. One end of this-block d is provided with a lug or longitudinal projection, 0, through which aset-screw, f, is passed, whichscrews into a similarlyformed projection upon the seat or bed-plate .A, or into the body of the frame or stock, as

may be preferred. Two or" these sockets or slidesA I) are attached upon the bottom side of the skate-stock, as shown in the drawin s. The two wedgeblocks d (shown in Figs. 1, J, and 7) are provided with suitable hearings or frame-work for the support of the rollers g, so

that the skate maybe used as a roller-skate upon a floor or pavement.

In Figs. 4 and 6 the skate is shown as converted into a blade-skate for use upon ice, an iron runner, 71, being" sulntitutcd for the rollers. In this form the blocks d are provided with jaws j, between which the iron or steel blade ii is secure y hold by one or more rivets, In case the blade or runner is made of cast metal, the blocks d may be formed thereon as stock. At every successive stride of the skater in skating forward, the blade is driven harder and tighter into the seat, and should the skater strike upon obstructions on the ice the same effect will be produced, rendering a disconnection of theiron from the frame an impossibility during the forward movements of the skater. The single set-screw f at the heel of the skate, Figs. 2, 4, and 6, is all-sufficient to hold the iron in place during the backward movement. 7

Although I insist that the dovetail shape of the block d and its corresponding seat A b shouldbe combined with the longitudinal wedge shape (more clearly shown in Fig. 5) in order to obtain the most perfect and rigid connection of the two parts, I do not debar myself from using either the dovetailed or.

the wedge shape singly. Should it be pre ferred, for instance, 'to form the sides I) of the seat A b, as well as the block (I, of wrought metal, then the dovetail shape shown in Figs. 3 and 4 may be dispensed with, and the longitudinal wedge shape will be sufiieient to furnish a firm and rigid connection of the two parts. The sides or bars 7) may in that case have an angular or L-sha-ped cross-section substituted for their dovetailed form, and will overlap the edges of the block (I, which is slid in between the laps.. In this modified form of the block (I and its seat, the wedge shape is indispensable.

My improvement is more especially designed for and adapted to the cheaper class of skates, principally used by children; but it may also be applied in the construction of the more complicated varieties of and improvements in both the roller and the ice skates.

I claim as my invention- 1. In a skate, the combination of the bedplate A and bars b, for reception of wedgeshaped block d, substantially as shown, and for the purpose described.

2 The bed plate A, with beveled side bars, b lfi for reception of wedge-shaped block (I,

secured to the stock of the skate by inc-ans wed ge-shaped blocks (1 d, with jawsjj, adapted to the corresponding beveled side bars, I b, 01' the bed-plate A, secured by set-screw 1", projected through the lug c, substantially as shown and described.

5. The bed-plate A I), connected to or forming part of the frame of a skate, for the purpose and substantially as described.

6. The wedge-shaped block d,-in combination with the bed-plate A b, for the purpose and substantially as set forth.

7. The set-screw f, in combination with the wedgeshaped block d and bed-plate A b, for the purpose and substantially as herein described.
