20,1938.l 1'.. R GOETTIE. 2,140,955 l ROLLER SKATE. BRAKE l Filedl Nov. 22, 1937- INVENTOR.-

Patented Dec. 20, 1938 UNITED s'rnfrrfzs PATENT OFFlCE Z Claims.

This invention relates to a brake for roller skates and it consists in the constructions, arrangements and combinations herein described and claimed.

It is an object of the invention to provide a structure in which simultaneous braking action will be applied equally to each of the front and rear wheels of a skate.

It is also an object of the invention to provide a brake structure which may be readily installed upon skates now in use.

It is a still further object of the invention to provide means for manually applying the brakes and provide means for automatically releasing the same.

Additional objects, advantages and features of invention will be apparent from the following description considered in conjunction with the accompanying drawing, wherein Figure 1 is a side elevation of a skate, partly in section, showing my brake applied.

Figure 2 is a fragmentary bottom plan view.

thereof.

Figure 3 is a perspective view of a guide member employed in the brake.

Figure 4 is a perspective view of one of the brake shoes.

Figure 5 is a plan View thereof. Figure 6 is a front elevation of a pair of skates equipped with the brakes and illustrating the operating means therefor.

There is illustrated in Figures 1 and 2 a skate I0 having front and rear bracket members II and I2 to which there is mounted a truck I3 by means of a bolt I4. The bracket II is carried by a forward section I5 extensibly connected with a rear section I6 associated with bracket I2, the sections being retained in adjusted position by means of bolts I1. The construction described is well understood in the art.

Upon each of the bolts I4 adjacent their inner ends there is resiliently mounted a brake shoe I8, the shoes being apertured for reception ofthe bolt, a helical spring I9 being interposed between 45 the shoe and truck I 3. The shoes I 8 comprise oppositely disposed contact portions 20 for braking action against respective rollers 2l of the skate,

and an upstanding offset apertured lug k22. The

spring I9 functions to maintain the brake in re- 50 leased position yet movable to engage the wheels for braking action as will be described- A box-like guide 23 is xed to the underside of the skate and preferably includes a tongue24 of a thickness to pass between the extensible sections I5 and I6 and secured therebetween upon tightening of the bolts Il. The tongue 24 also includes a hook portion 25 adapted to engage the inner longitudinal edge of the section It of the skate. The guide 23 will be positioned upon the skate with the 5 entrance opening 2G disposed toward the outside of the skate, the entrance and outlet edges of the guide being rolled to prevent chai-lng or excessive wear upon actuator straps 2l threaded therethrough, as will be described. 10

The straps 2l extend downwardly from a belt 28 adapted to be fixed about the waist of the skater, the straps extending downwardly upon the outside of the legs. The straps have branched extensions 29 and 39, the latter being threaded 15 through the guide 23, the branch 29 being secured to the extension 22 of the rear brake I8, while the branch 3E] is secured to the front brake extension 22.

1n use, when a skater desires to slow down or 2o stop, it is merely necessary to give an upward pull upon the straps 2l. This will effect a pull upon the extensions 29 and 39, causing movement of the brake Shoes Z into contact with the rollers 2l, thereby retarding rotation of the rollers. 25 When such action takes place, the springs I9 will be compressed, and with release of pull upon the straps, the springs will return the brakes to normal released position.

While I have described the invention specifi- 30 cally and shown a preferred construction in the drawing, this is by way of illustration only, and I consider as my own all such modifications as fairly fall within the scope of the appended claims. f 35 I claim:-

1. In a roller skate, having front and rear truck mounting brackets, a roller truck for each bracket, a bolt connecting respective brackets and trucks, a brake shoe loosely mounted upon the 40 bolts, said shoe having oppositely disposed roller contact portions, a helical spring on each bolt interposed between a portion of the truck and the brake shoe normally holding Vthe brake shoes in released position, each of said brake shoes having an upward offset extension, a guide housing upon the underside of the skate, a pull strap threaded through the guide and having connection with re-V spective upward extensions of the brake shoe.

2. The structure of claim 1 in which the pull 50 strap includes an adjustable belt for attachment upon a skater.
