UNITED STATES PATENT OFFICE.

JAMES CARRIE, OF BROOKLYN, NEW YORK.

ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 482,721, dated September 20, 1892.

Application filed May 18,1892; Serial No. 433,426. (No model.)

To all whom it may concern:

Be it known that I, J AMES CARRIE, a-citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Roller-Skates, of which the following is a specification.

I will describe a roller-skate embodying my improvement, and then point out the novel features in the claims.

In the accompanying drawings, Figure l is a top view of a roller-skate constructed according to my invention. Fig. 2 is a central longitudinal section of the same. Fig. 3 is an inverted plan view thereof. Fig. 4 isatra-nsverse section taken at the line x as, Fig. 2. Figs. 5 and 6 are respectively an inverted plan and elevation of certain parts of a looking device.

A designates a foot-plate made in two sections A A having overlapping end portions adjustably secured together.

B is a heel-grip provided with a slot 1) and having an upwardly-turned end 6', capable of being adjusted against the heel of a shoe by means of a finger-piece D The opposite end of this grip has its central portion 11 sunk to fit an enlargement of a slot 61- contained in the section A. The sections A A of the foot-plate and the grip B are connected together by means of a rivet a and a bolt a each having their head portions resting on the grip l3 and their shanks extending through the slots b and a and through holes in the section A The rivet a is rigidly secured to the section A and is fitted to slide freely in the slots a and b. The bolt a has a square neck portion a to prevent its turning, and its head portion rests on the sunk part b in order to avoid having the shoe of the user resting thereon. The shank of this bolt extends through a locking device 0 and is provided with a thumb-nut a This locking device comprises a disk 0, secured to the section A by rivets c and provided with an annular inclined rim 0 forming a cam-surface.

c is a disk rigidly secured to or integral with a lever c and has an inclined rim corre sponding to that of the disk 0, against which it is held bythe thumb-nut a.

c is a shoulder formed in each disk to limit the motion of the lever when turned in a direction to release the parts. The lever c has an arm o to which is pivotally connecteda link (1, whose other end is loosely mounted on a washer d, adjustably secured to the slotted end of a reciprocating bar c. This washer is clamped to the bare by means of a bolt 01 and thumb-nut 02 The bar c has its forward end provided with slots e, converging toward each other, and in which are fitted to slide the shanks of rivets e These rivets are rigidlysecured to the inner extensions f of toe-grips j, which are supported by means of rivets f fitted in slots f and rigidly secured to the shoe-plate A. The inner extension of one of these toe-grips has a bifurcated or forked extremity f as shown in Figs. 2 and 3, and in which is fitted to slide the extremity or tongue portion f of the other or opposite toe-grip. By this construction the toe-grips are guided to move to and fro transversely of the skate.

G G are brackets, in which the rollers 9 have their bearings. Each bracket consists of two vertical side portions g'g united bya cross portion g and provided with flanges g, by which the brackets are rigidly secured to the shoe-plate. g g are journal-boxes extending between the hubs of each pair of rollers and having the axles of the latter loosely mounted therein. The journal-boxes g g are provided with grooves g g fitted to slide on, bifurcated end portions of the sides g 9 g is a coil-spring arranged between the journal-box and the cross portion g of the bracket and is secured in position by pro ecting studs g extending from the journal-box and the said cross-piece y 9 is a stop-plate secured at one end to the cross-piece g of the bracket and extending around the under side of an annular groove in the journal-box to limit the downward mo tion thereof. By this construction the coilspring serves as a cushion to afford an easy movement in use.

The bracket G may be provided with pro jections h, formed integral therewith,and between which the reciprocating bar c may be fitted to slide and caused to move in a direction longitudinally of the shoe-plate The operation of the device is as follows: The lever c is turned to a position shown dotted in Fig. 3, which loosens the parts sufficiently to adjust them to a shoe of any size. The nut d is then loosened and the bar 6 moved forward or backward to impart the requisite degree of lateral motion to the toegrips to fit the shoe of the user, after which the nut d is tightened to secure the washer d rigidly to the bar 6. The skate is then applied to the foot and the two sections A A brought together to fit the shoe lengthwise, after which the heel-grip B isinoved against the heel and the parts tightened together by the thumb-nut a The lever c is then turned to a position shown in full lines in Fig. 3, which imparts a movement to the toe-grips to grip the shoe and at the same time locks the two sections A A and the heel-grip I3 rigidly together.

Having now described my improvement, what I claim new, and desire to secure by Letters Patent, is

1. A support for a roller-skate axle, comprising a bracket G, secured to the shoe-plate and having two side portions g g provided with perpendicular slots open at the bottom, a journal-box extending the entire width of the axle between the h ubs of the rollers g and having fiat-sided and parallel grooves g 9 in which are loosely fitted the slotted portions of the sides g 9 a spring g and a stop-plate g, substantially as described.

2. The combination, in a roller-skate, of a shoe-plate, toe-grips having slotted extensions connected thereto and arranged to slide transversely thereof, a reciprocating bar provided with slots converging toward each other and engaging with pins secured to the extensions of the toe-grips, a link pivotally and adjustably connected to the reciprocating bar, means for guiding thelatter to move longitudinally of the skate, a lever having an arm pivotally connected to the said link, aheel-grip adjustably connected to the shoe-plate, a locking device, as O, for locking or unlocking the skate to or from a shoe, and a bolt, secured from turning, extending through the heelgrip, shoeplates, locking device, and lever and provided with a thumb-nut to clamp the said parts together, substantially as described.

3. In a roller-skate, the combination of a shoe-plate, toe-grips, each having a slotted extension, one of which is fitted to slide within a bifurcated end portion of the other, rivets secured to the shoe plate and extending through the slots of the extensions to support and guide the same, a bar fitted to move longitudinally of the shoe-plate and having slots converging toward each other and in which are fitted to slide pins secured to the extensions of the toe-grips, and means for reciprocating the said bar and locking the same in position, substantially as described.

4:. In a roller-skate, the combination of a shoe-plate composed of two overlapping sections, a heel-grip adj ustabiy connected thereto, a locking device comprising a disk secured to the front section and having an annular inclined rim forming a cam-surface against which bearsacorresponding cam-surface of a disk secured to the hub of alever, and a bolt, prevented from turning, extending through the heel-grip, front and rear sections of the shoe-plate, and locking device for clamping the said parts together, substantially as described.

55. In a roller-skate, the combination of the shoe-plate A, composed of two longitudinallyadjustable sections A A overlapping each other, the heel-grip B, and toe-grips ff, adjustably connected thereto, the reciprocating bar 6, having slots converging toward each other and adapted to impart a lateral to-andfro motion to the toe-grips, the link (I, pivotally and adjustably connected to the bar 6 and to an arm of a lever 0 and the locking device O, comprising the cam-disks 00 the bolt a thumb-nut a and lever 0 the latter being arranged to operate the toe-grips and lock the same, together with the heel-grip and thetwo sections of the shoe-plate, together sim ultaneously, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 10th day of May, 1892.

JAMES CARRIE.
