ADJUSTABLE SKATE.

Applic ation' filed January 17, 1924. srm 110.686,?56. I

To all whom it mar concern:

Be it known that J OHN CAnLsoN, citizenof the United States of America, residing at 919 Liberty St, Springfield, in the county of Hampden and State of Massachusetts,

has invented certain new and useful .Im-

provements'in Adjustable Skates, of which vide a skate with a rigid one piece runner-or blade and a shoe support capable ofbelng connected. to the runner or blade in various longitudinal positions to fit various persons.

Another object of the inventlon is the provisionlof a runner blade for skates with a T-shaped supporting head.

\Nith the above and other ob ects in view the invention consists in certain new and useful constructions, combinations and, arrangements of parts, clearly described in the following specification and fully illustrated in the accompanying drawings, in which:-

Fig. 1 is a side elevation of one form of my invention. 1

Fig. 2 is a plan view thereof.

Fig. 3 is a transverse sectional view.

Fig. 4 is a detail perspective view of one of the shoe supporting devices or cups detached from the runner.

Fig. 5 is a side elevation of the modified form of the invention.

Fig. 6 is a detail view in perspective of a foot plate connection.

Fig. 7 is a detail transverse sectional View of a modified runner blade.

Referring to the accompanying drawmgs illustrating the practical embodiment of my invention 5 designates a runner blade which is preferably made with a T-shaped head 6 and a straight edge 7 for engaging the ice. The forward end of the runner blade 5 is curved upwardly and forwardly and is also, on its upper side, curved forwardly and downwardly. The rear end of the blade is curved rearwardly and downwardly and slightly upwardly and rearwardly on its lower side.

The rear end of the runner blade 5 is provided with a series of longitudinally spaced openings 8, located under the T-shaped head thereof and in parallel relation therewith. The heel supporting cup 9 is adjustably connected with the rear end portion of the blade by means of clamping jaws 10 and 11 formed on the base of said cup, which are shaped to [TENT 4 V snugly fit the T-shaped head ofthe runner,

blade. Through these jaws. the rivets 12 are extended after the required longitudin'aly ad ustment has been made, and are thenclinched or headedin fixed position, so asto firmly hold the heel supporting cup. on the runner blade. This heel" supporting cupis formed with an attaching head flange 13, whereby the cup may be connected positively to the heel portion of a skating shoe. 1

The toe supporting plate 14: is connected at itsrear end tothe supporting cupf15,

the base of which is formed with flanges.

or clamping jaws, 16 f and 17, which are shaped to snugly grip the T-shapedhead of the'runner blade. These jaws. are adjustably connected with: the runner blade through rivets 18 which may be extended through the series of holes 19 formed in the blade 5 immediately below the T-shaped head thereof and in parallel relation thereto. The cup 15 is provided with an integral flange 15* on its head which is riveted or otherwise connected directly to the footplate 14. The forward portion of thefoot or toe plate 14: is supported by means of the angle brace 20, which is connected by'rivets or the like at its upper end to the forward end of the toe plate, andat its lower end to the lower end being formed with clamping jaws 21, which are shaped to snugly grip the T- T-shaped head of the runner blade; said shaped head of the runner blade, and which are connected to the blade 5 by means of one or more rivets 22 extended through one of the series of holes 23 formed in the runner blade immediatelybelow the T-shaped head thereof. The brace 20 could be formed in tegral with the toe or foot plate if desired.

In Figs. 5 and 6 I show a modified form of the runner and the supporting connection for the forward end of the toe or foot plate, consisting of a runner blade 25 which is provided with an upstanding integral arm 26 to which the forward end of the foot plate 27 is connected by means of the brackets 28,

said foot plate being connected to the 1 with integral lugs 35 which are folded down- T-shaped wardly to engage the edges of the head 32.

: By means of'my invention a single runner blade can be used for various sizes of skating shoes, by simply varying the connection between the blade and the supporting mem ber.

The ice engaging and wear resisting straight edge maybe tempered glass hard and the T-shaped head given a lower temper,

so that the edge will maintain a smooth runningaction and the head will not be brittle and will resist bending and distortion.

The cups are preferably drawn with tapered walls, so as to give great strength.

The runner blade may be drawn or drop forged from T-shaped iron or steel, and its ends and edges ground to give the required accuracy.

Having described my invention I claim 1. An ice skate consisting of a runner blade having an integral T-shaped longitudinal head, and a shoe provided with separated jaws adjustably clamped to the T- shaped head. 1

2.,An ice skate having a runner blade provided with an integral Tshaped head and an upstanding integral arm, and a toe plate having connection with said arm and provided with a support at its rear end having clamping jaws straddling the T-shaped head and positively connected thereto.

3. An ice skate comprising a runner having a blade providing a rigid bearing edge and an integral T-shaped head providing lateral shoulders on the opposite sides of the blade having bottom faces substantially right angular to the sides of the blade, and shoe supporting means provided with pendant separated jaws clamped directly to the blade and having interlocking engagement with the T-shaped head by correspondingly shaped portions.

4. An ice skate comprising a runner hav ing an integral T-shaped head providing lateral shoulders, the underfaces of said shoulders being substantially at right angles to the sides of the runner, and a shoe supporting member consisting of a cup having an attachingv flange on its upper end and pendant jaws shaped to snugly fit the T-- shaped head, the cup being mounted on the T-shaped head and the jaws'being secured to the sides of the runner below said T- shaped head. 7
