I ROLLER SKATE AND WHEEL THEREFOR.

Application filed May 25,

To all whom it may concern: Be it known that O'r'ro W. BOCHE, a citizen of the United States, and resident of Bridgeport, in the county of Fairfield and State of Connecticut, has invented certain new and useful Improvements in Roller Skates and Wheels Therefor, of which the following is a specification. I

This invention relates to roller skatesand to wheels therefor. I

An object of the invention is to produce an improved roller skate of simple, practical and durable construction and of llght weight, and to provide therein novel means for mounting the skate wheels, sald novel means consisting of certain of the elements of both said skate andwheels. A further object is to provide a novel and improved skate wheel that can be ec0nom-' ically manufactured and will be reliable and eflicient in use.

With the above, as well as .other, objects in view, the construction, arrangement and combination of parts constituting the. invention will now be fully described, reference being had to the accompanying drawing forming a part of this specification and wherein like reference numerals designate corresponding parts throughout the several figures, and will be hereinafter specifically claimed, it being understood that such changes in details ofconstruction and arrangement of parts maybe made as fall within the spirit of the invention and within the scope of the claims.-

In said drawings,

Fig. 1 is a side elevational viewon a reduced scale of a skate embodying the. fea- Y angular positions with respect to the foot tures of the invention. Fig. 2 is a sectional view on line 2'2 1n Fi 1' Fig. 3 is a sectional view Fig. 1;

on line 3-3 in Fig. 4 is a detail perspective View of portions of the foot plate-and one of the side plates, illustrating the connection betweeh said plates; and

Fig. 5 is a, sectional view, corresponding 1 with the showing of Fig. 3, disclosin a modified form of axle, that may be utilized for. mounting the skate wheels. 7

Of the novel skate, 10 denotes a metal foot plate and 11 and 12 denote, respectively,

to rest 1 1921. Serial No. 472,430.

clamp members of ordinary or preferred constructlon and for an obvious purpose.

13 and 14 denote, respectively, spaced" apart, parallel metal side plates arranged longitudinally of the foot plate adjacent the opposite side edges thereof and extending downwardly at right-angles therefrom to provlde supportin means for the solid axles,

denoted by 15, of t e skate wheels. ,The side plates are cut away at'the several locations indicated 16 for the sakeof li htness, thus providing attaching portions 1 positioned directly above the axles', whereby the side foot plate, the detachable connection being preferably made in the manner best shown the slot 19, as will be understood. I

The axles 15 are provided at their 0p'po-- site ends with reduced portions 23, and the side plates'are provided with openings tov snugly receive said reduced portions. The axles are fixed against rotation in the side plates, so that while one of the reduced portions 23 may be cylindrical, the otherone is platescan be detachably connected with the.

flat 'on one side, as best shown at 24in Fig.

L See also the hole25 in that portion of the side plate '13 shown in Fig. 4.. The side plates'may be held in their rightplate and against the ends of the larger portions of the axles 15 by means 'of screw bolts plates and each provided with a head 27 anda nut 28 bearingagainst the outer faces, respectively, of'the si e plates. .29 represents bushings located upon thecscrew bolts and arranged between the side plates, said bush ingsjbeing of the same length asare the larger portions of the axles, .foran apparent reason. v

In Fig. '1 of the drawing I have shown' a skate equipped with four axles, with an equal number-of attaching portions 17, and

7 the running surfaces of the two intermediate skate Wheels will be at slightly lower elevation than are @the running surfaces of the front and rear wheels.

It will be evident that the side plates cannot be disconnected from the foot. plate so K long as said side plates bear their ri htlllii angular relation to the foot plate. W en, however, the screw bolts 26 are removed from the side plates, saidlast mentioned" plates can be readily swung outwardly to remove the tongues 17 from the slots 19.

The skate wheels are all du licates of each other. Of each of said whee s, 30 denotes a pair of disks detachably secured together as by means of small screw bolts 31.-

Each of said disks is provided with a central opening 32 to freely receive the solid axle 15, and adjacent said opening the disks are flared outwardly, as denoted at 33, to receive metal balls, denoted by 34, adapted to rest within a circumferential groove 35 in the periphery of the axle 15 and arranged midway between the ends of the larger portion of said axle. Said disks are also flared outwardly adjacent their circumferential margins, as denoted at 36, to provide a bearing rim for the snug reception of the tire 37 composed of hard rubber or other suitable material. I I

It has already been remarked that the solid axles 15 are fixed in the side plates. It is to be now remarked that the outwardly flared portions 33 of the disks comprise the hubs of the skate wheels, said hubs riding over the metal balls 34 andsaid balls ridin over the groove 35 of the axle.

In Fig. 5 I have disclosed a modified form a of solid axle which may be employed in connection with the features of the present invention and which has been designed for use in the instance of double wheel skates. The foot plate, side plates and wheels in the present embodiment may be of the approximate construction of those already do- I scribed.

The axles 15, extending throu h the side plates and projecting some litt e distance beyond each side plate, as denoted at38, are

provided with a collar 39 en aging the side plate 14. and with a threade portion 40 to receive a nut 41 engaging the side plate '13. Bushings 42, one for each axle 15 and between the side -plates, serve the purpose, already described, served by bushings 29. Obviously, a single wheel skate axle 15- can be rovided with a bushing similar to the bus ing 42 to serve the same purpose, and

when such an arrangement is employed, the

- screw bolts 26 may be dispensed with if this is found desirable. against rotation tion 24'.

The grooves 35, 35 in the projecting portions 38 of the axle 15 serve the same purpose as do the grooves 35 in the axles 15.

Having thus fully described the invention, what I claim and desire to secure by Letters Patent is:

1. A. roller skate comprising a foot plate, a pair or parallel, disconnected and spaced apart side plates extending downwardly at The axle 15' is fixed by means of the fiat poriright-angles from adjacent the opposite edges of the foot plate for a proximately the length of said skate, space a art means on each side plate detachably an separately connecting the, same to said foot plate, said means in the instance of each side plate being arranged along, the greater part of the length of said skate, means forinsuring the positions of the side plates, axles fixed in and extending between said plates, and wheels on said axles...

2. A roller skate comprising afoot plate,

a pair of parallel, disconnected side plates extending downwardly at right-angles from adjacent the opposite edges thereof for apthrough a, slot adjacent the sideedge of saidfoot plate. I,

'3. A roller skate comprising a foot plate, a pair of parallel side plates-extending downwardly at'right-angles from adjacent the oppositeedges thereof, means for detachably connecting said side plates to said foot plate,-axles fixed in and extending between said side plates, means for insuring the positions of the side plates, and wheels on said axles, said connecting m'eans in the instance of each side plate including a tongue extending atright-an les from the flat upper edge of said side p ateand passing through a slot adjacent the side edge of said foot late, the body of said tongue resting in a epression in said foot plate.v

4. A roller skate comprising a foot-plate,

a pair of parallel side plates extending downwardly at right-angles from. adjacent the opposite edgesthereofimeans for detachably connecting said side plates to said foot said side plates, means for insuring the positionsof the side plates, and wheels on said axles, said connecting means in the instance of each side plate including a; tongue ex- "plate, axles fixed in and extending between tending at right-angles from the flat upper edge of said side plate and passing through a slot adjacent the side edge of said foot plate, the body of said tongue resting in a depression in said foot plate, and the rightangular bend in said tongue located in the plane of said foot plate and contiguous with the Wall of said slot farthest 'from said depression.
