Each of the . ' pulley-like wheels or rollers has a groove 20 in its It has for one of its objects to provide a novel periphery for the engagement of the belt I6, and skate device of this character which is so lde 5 each has an axle in the form of a bolt 2 I` for sup signed and constructed as to afford enjoyment porting it on the frame. By preference, the heel and exercise to the user, and which employs a bracket I1 is provided with a plurality of horizon combination of rollers and endless belt construc tally alined axle-receiving openings 22 while the tion wherein the lower stretch of the belt consti toe bracket I8 has horizontal slots 23 therein for tutes a ground-engaging track over which lthe supporting the axle of the roller I4, whereby the rollers travel during the skating operation. end rollers may be adjusted toward and from Another object of the invention is to provide each other to accommodate and adapt the frame a roller skate which is simple, light and inexpen I0 to different sized shoes. Furthermore, the lon larly to roller skates. sive in construction, whose rollers are adjustable gitudinal slot adjustment provided in the toe bracket enables the companion roller to be ad belts, and whose belt and roller construction is justed as desired to place the proper tension on such that the belt is eifectually retained on the the belt I6. For the purpose of effectually retain rollers and serves to protect the rims of the rollers ing the toe roller I4 in a set position of adjust and prevents them from scratching the skating ment, a washer 24 is applied to its axle and has iloor. 20 locking teeth 25 on its inside face which are A further object is to so arrange the rollersand adapted to mesh with corresponding rows of ser belt that the skate will have a rocker action. rations or notches 26 formed in one side of the toe Other features of the invention reside in the bracket I8 in parallel relation to its companion construction and arrangement of parts herein slot 23. after described and particularly pointed out in 25 The intermediate roller is adjustable vertically the appended claim. on its bracket I9 and for this purpose the latter In the accompanying drawing: has upright slots 21 therein through which its Figure 1 is a side elevation of a roller skate em axle extends.

Figure 3 is an enlarged vertical sec 30 is provided with a washer of the same type as the tion taken on line 3-3, Figure 1.

Figure 5 is a perspective view of one of 21. As shown in Figure 1, this intermediate roller the lock washers for adjustably retaining a roller I5 preferably assumes a position below the axial to accommodate diiîerent sized shoes as well as in a set postion of adjustment on the skate-frame. 35 plane of the end rollers I 3 and I4 to cause the belt ' In the preferred embodiment of the invention to take a substantially arcuate path of travel shown in the drawing, the same consists of a along its lower stretch and accordingly afiord a frame I0 of substantially U-shape in cross sec rocker-like action to the skate. tion which carries the roller elements of the skate The belt I6 is preferably of frusta-conical shape and which is rigidly secured to the shoe ~I-I by 40 in cross section, and the roller-grooves 20 which bolts I2 or like fasteners. The roller elements consist of ball-bearing supported rollers or pulley receive it are of similar cross section, as shown in Figure 3. 'I'he periphery of the belt projects like wheels I3 and I4 disposed, respectively, ad beyond the peripheral edges of the rollers and its jacent the heel and toe ends of the frame, and outer or ground-engaging face is preferably made intermediate like roller or pulley-like wheel`I51 45 of rubber and is crowned or arched in cross sec disposed between the end rollers, and an endless tion. The side edges of the belt are straight and belt I6 of rubberized or like material passing are coextensive or in registering alinement with around the several wheels, the lower stretch of the side walls of the roller-grooves to resist dis the belt constituting a ground-engaging track placement of the belt from the rollers. Adjacent over which the roller-like wheels travel during. thev 50 their bottom faces the opposite side walls of the skating operation. belt-receiving groove are widened by the pro The frame I0 is provided with depending end vision of circumferential recesses 28. By this con walls or bracketsI Il and I8 on which the com struction, the belt has a tendency, during the panion rollers or wheels I3 and I4 are respectively skating operation, to be crowded into the roller mounted, and intermediate depending wall or 55 grooves and .'to be thereby expanded into the 2,412,290 l* gaging the grooved rollers, said belt and roller widened portions or circumferentiaI recesses 28 to grooves being substantially frusto-conical in cross section with the tread portion of the belt project thereby prevent the belt from accidently coming off the rollers, as when skating round turns. Fur ing beyond the periphery of the rollers, and thei thermore, the belt projects somewhat beyond the peripheral edges of the rollers and ythereby serves . as a guard or protector and prevents the edges of the rollers from scratching the skating floor. I claim as my invention: A skate, of the character described„comprising a framefadaptedvforattachment toèa shoe, longi tudinally-alined, grooved rollers applied to the toe and heel ends of said frame, an endless belt err-_ lower stretch of said belt constituting a ground engaging track over which the rollers travel dur ing the skating operation, the side Walls of the roller-grooves adjacent the bottoms thereof hav ingy circumferential grooves ,therein4 into which 10 the-inner yportion of the beltíisgadaptedto extend.
