V SELF-ACTING BRAKE FOR ROLLER-SKATES.

SPECIFICATION forming part of Letters Patent No. 521,181, dated June 12, 1894. Application filed October 10, 1893. Serial No. 487,778. (No model.)

To 00% whom it may concern.-

Be it known that I, J OSEF RIEDEL, residing at Vienna, in the Province of Lower Austria and Empire of Austria-Hungary, have invented certain new and useful Improvements in Self-Acting Brakes for Roller-Skates, of which the following is a specification.

Braking apparatus for preventing a backward motion of the roller skates are very desirable not only for beginners in their first period of learning how to skate but also for all roller skaters it is desirable. The beginner particularly fears backward motion during the skating as well as while standing still because of the liability to fall; but even the expert, while skating will find a great advantage in braking the backward motion of the skate which rests momentarily upon the ground at the time he wishes to push himself forward or to increase his speed; and this is especially true when skating up an incline where the skate that rests upon the ground tends more particularly to roll backward so that it wouldbe impossible to obtain any stability of the same upon the ground without braking apparatus. It is also desirable when the skater desires to stand still.

The roller skate of the present invention comprisingself acting and removable braking apparatus for preventing its backward motion is illustrated in annexed drawings.

Figure 1, is a side View of the roller skate duringthe forward motion; the position shown by dotted lines represents the parts in the position they adopt when the roller skate is stopped by the brake, that is when the foot supported by the roller skate presses backward toward the ground or even at the moment that the skate tends to roll backward. The fore and rear roller bearings show two difierent arrangements. Figs. 2*-2 show central vertical sections of the two different A pair of tension springs arranged 5 5 slide in longitudinal slots of the'plate a and 5c are prevented from falling out by means of pins 0'. The springs or half springs, f draw the plate 1) against the plate a and thus the said plate I) is fastened, as also the plate a, to the foot gear. the plate a serve as supports for the springs, or half springs, f and f; and the rods 0" which project through said springs serve to guide them and these are made of one piece with the clamps c.

The two part sole plate a b, whichhowever can be constructed of one piece without interfering with the principle of the invention is provided at the side with two pairs of flanges d, d, bent downward and also with two flanges e e bent downward which latter form the brake blocks for the rollers. Those flanges d d d d e e can also be fixed to the sole plate a b by any suitable means, as screws, rivets or the like.

The rollers r, r, are journaled in the bearin gs t t by means of their axles s s which bearings are made of one piece with the frame a; (see the front roller r and its bearing;) or the frames consist of the two side surfaces u connected by means of the distance bolt to, see the rear roller 0" and its bearing.

Each of the frames to is pivotally connected with the downward bent pair of flanges d d of the sole plate a b by means of a pair of gudgeons o o and the weight of the person wearing the skates is transmitted through the flanges d d d d through the gudgeons o o o 2) through the side plates u u' u a through the The upward bent flanges a of 6 5 bearings tttt upon the side pivots of the axles 5 s s and from there through the axles s s and the rollers r r to the ground.

The pivotal motion around the gudgeon 'v is only slight, being limited on one side by the brake block e against which the roller r rests'in the braking position and on the other side by the lower surface of the sole plate 1) (or a) against which the upper surface to of the horizontal cross-piece to (or the upper edge of the distance bolt u) comes in contactduring the forward motion, said contact pieces can be provided with cork, wood, leather or rubber layers which on one side increase the brake power and on the other side prevent noise at the moment of the coming in contact. In order to prevent the brake from working, it will simply be necessary to pass the pin .2 through the holes of the sides a and flanges d which holes register when the different-parts are in the position iudicatedby the full lines in Fig. 1, whereby the frame it is held rigid and cannot turn around the pins 1).

When the skate is moved forwardwhereby the rollers turn in the direction of the arrows cl d the parts remain in the position indicated by fulllines in Fig. 1 and the rollers 1" 0', keep at a distance from the brake blocks (2 6. But when" the rollersr r (or only one of them) have a tendency to turn in the opposite directiontof the arrows B B), which will occur ifthe skater (voluntarily or not) moves backward; each of the frames u will then swing into the second position, shown in Fig; 1 by dotted lines on account of the friction of the contact surface of the roller with the ground;

comprisingthe flanges e e bent down from the main frame, substantially as described.

2. In combination in a roller skate the frame having the side flanges d d bent downwardly and also the brake blocks a, the rollers, the supplemental frameshavingsides overlying the flanges d (l and pivoted thereto, said flanges and sides being perforated and the pin passing through the said holes to hold the frames u to the flanges cl (1 against turning, substantially as described.

In witness whereof Ihereunto set myhand in presence of two witnesses.

JOSEF RIEDEL. Witnesses:
