ROLLER-SKATE.

Specification of Letters Patent.

Patented may at, rate.-

To all whom it may concern:

heel end of the skate.

The principal object of my invention is to provide a roller skate having improved means for automatically checking the rotation of the rear wheel or roller to thereby prevent the unskilled skater from falling when his heels tend to slip from under him.

, The device will also be found effective for the 'skilleduser to quickly come to astop when desired by merely raising-the front rollers from the ground.

My improved skate dispenses with the additional brake roller which has been heretofore tried for accomplishing the aforesaid purpose.

My invention contemplates more particularly certain improvements in the construction of skates having an automatic brake ,at the heel endthereof.

. Figure 1' is aside elevation of a roller skate embodying the main features of my present invention; Fig. 2 is an underneathplan view thereof; Fig. 3 is a longitudinal central section of the rear or heel end of the skate, certain of the-parts being shown in elevation; Fig. 4 is a similar view to Fig.

3, but with the parts in the positions as-- sumed when the skate is tilted either accidentally or by design; and Fig. 5 is a perspective view of abrake block employed in the skate, shown detached therefromn Referring to'the drawings, in the particular embodiment of my invention; thereln shown, 6 is the sole plate ofany desired construction, but preferably made in two sections7 and 8,'longitudinal ly extensible with respect to each other.' The sole clamp 9 and the heel strap 10 may be ofany desired construction. The front wheels or rollers 11 are supported from the under side of the front section 7 of the sole plate by means of a bracket 12 which may also be of any preferrd arrangement. While there are shown two front rollers 11, it will be obvious that a slngle centrally disposed roller may be used in lieu thereof. I

Secured to the under side of the heel section 8 of the sole plate 6 is a bracket 18 having two downwardly depending ears 14 each of which is provided with an inclined slot 15 in which is slidably mounted an arbor 16 upon which a single ,rear wheel or roller 17 is journaled. The inclined slots 15 extend upward and forward and are .each open at the forward end so that the wheel arbor 16 with the wheel 17 mounted thereon may be easily removed when it is desired to substitute a new wheel. The

arbor 16 is engaged on each sideof the.

roller or wheel 17 by the slotted ends of a U-shaped bail piece 18 which extends forward and upward in the same general direction as the slot 15, and which is engaged at its forward, transversely extending portion 19 by a spring 20. The spring 20 encircles a rod 21, being maintained in place. thereby, and bears at its other end agalnst a downwardly extending lip 22 of a bracket 23 which also supports the rod 21. The

transversely extending portion 19 of the bail 18 is suitably apertured so as to be capable of slight movement on the rod 21 upon which the spring 20 is mounted. It

will be seen that the roller 17 is capable of a slight forward and upward movement against the tension of the spring 20. When the roller is thus moved forwardin a manner to be hereinafter set forth 1t w1ll en:

' counter a brake block 24 which is removably mounted in a slotted downwardly extending member 25; The brake block 2;

consists of a crescent shape .piece of metal or other suitable material-having a lug on its rear side which is provided with slots -.the slot 32 of the supporting member 25,

' eration. I 'Havm retaining member carried ing said brake blockin porting bracket. 1 I skate, the combination ofthe rear roller, a brake block supported agiworking rollers brake block and provides an efficient means of releasing the brake block for the purposeof replacement when the same is worn. The bracing member 30 can readily be removed by unscrewing the nut 33 which is carried by the bolt 81 to thereby release thebrake block.

The operation of the apparatus is as follows :When both front and rear wheels or rollers rest upon the ground, the spring 20 will be of such strength as to properly maintain the rear roller at the rear end of the inclined slot 15 and out of contact with the brake block 24. When, however, the foot of the skater is inclined and the front rollers lifted from the ground, either accidentally or through design, there will be a critical angle at which the roller arbor 16 will be moved forward and upward,with-' in the slot 15 and until thewheel 17 bears against the brake block 24 and further rotation of the" roller will thereby be checked. It will be seen that the arrangement is such that while being extremely light it will nevertheless be quite durable and-efiicient for its designed purpose. It will also be seen that the rear roller upon which the checking act-ion occurs is one of the main and that no auxiliary rollers are employed to efiect the braking 'op-- characteristic features of my invention,

what I claim as new and desire to secure by Letters Patent is 1. In a roller skate, the combination of the rear roller, a brake block supported ad- ]acent said roller, a bracket. in which said 's removably mounted, and a 1 by the framework of the skate for maintaining said brake block 1n its supporting bracket.

2. In a roller skate, the combination of the rear roller, a brake block supported adacent said roller, a bracket having a slot 2 I in which said brake block is removably mounted, and a. retaining member carried by-the framework of the skate'for supportthe s1ot of the sup- 3. In a roller thus described the nature and jacent said roller, a bracket having a slot in which said brake block is removably mounted, and a retaining member carried by the framework of the skate for support- 1ng said brake block in the slot of the'supporting bracket, said retaining member also serving as a brace the roller bears against said brake block.

4. In a roller skate, the combination of the rear roller, an arbor upon which said roller is journaled, a bracket having slots in which said arbor is slidably mounted, the slots in said bracket being inclined forwardly and upwardly and being open at the forward end,'a brake block mounted adjacent the roller and against which said roller is adapted to impinge, and spring means for normally maintaining said roller out of contact with said brake block.

5. In a roller-skate, the combination of the rear roller, an arbor upon which said roller is journaled, a bracket having slots in which said arbor is slidably mounted, a brake block mounted adjacent the roller and against which said roller is adapted to impinge, a bail member having slottedends which engage the roller arbor, and a spring bearing against said bail member to norto resist the strain when mally maintain the roller .out of contact with the brake block.

6. In a roller skate, the combination of the rear roller, an arbor upon which said roller is journaled, a bracket having slots in which said arbor is slidably mounted, a brake block mounted ad'acent the roller against which said roller is adapted to impinge, a bail member having slotted ends which engage the roller arbor, a rod sup ported from the underside of the skate and upon which said bail member is guided, and

a spring-surrounding said rod and bearing against said bail member to normally maintain the roller out of contact with the brake block.
