ROLLER-SKATE.

Specification of Letters Patent.

Patented Sept. 21, 1915.

Application filed November 22, 1913. Serial No. 802,401.

To all whom it may concern:

Be it known that I MAX FINKLEs'rEiN a citizen of the United States of America, re-

My invention relates to roller skates, and

resides in certain peculiar yielding supports or bearings for the rollers, and in certain details of construction, all as hereinafter set forth.

The primary object of my invention is to produce a strong, durable, and comparatively inexpensive roller skate, which has yielding or resilient supports or bearings for the axles upon which the rollers are mounted, whereby the foot of the wearer of such skate is cushioned and protected from shock and jar, and at the same time the act of skating is made easier and becomes more pleasurable.

A further object is to provide means in such a skate for readily introducing the springs employed therein, and preventing such springs from becoming displaced after all of the parts have been properly assembled.

Other objects will appear in the-course of the following description.

I attain the objects and secure the ac vantages of my invention by the means illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a roller skate which embodies a practical form of the invention; Fig. 2, a rear end elevation of said skate; Fig. 3, a front end elevation of the same; Fig. 1, a detail showing one of the hangers and the-bearing and guide block therein, as such block appears before the introduction of the spring into such hanger and the insertion of the axle in such block, the latter being partially broken away or in partial section, and, Fig. 5, an end elevation of one of the bearing and guide blocks.

This invention is applicable to skates having, two rollers, three rollers, or four rollers.

As herein shown it is applied to a skate hav-v ing three rollers, that is, two rollers behind and one in front.

It will be observed that the hangers for the roller axles, as shown in the drawings,

are arranged obliquely to the rest of the frame orto the heel and foot plates, those behind extending downwardly and rearwardly, and those in front extending downwardly and forwardly, but it is'to be noted in this connection that the angles thus formed between said hangers and said heel and foot plates may vary to any extent desired, even though the perpendicular should be nearly or quite approached.

The skate illustrated is of the extension, heel-strap and toe-clamp type, but it is to be understood that my invention is not restricted to any particular general type of skate, since it is applicable to practically any and all. types.

The skate which appears in the drawings,

comprises a heel-plate 1 provided with heel flanges 22 for straps 3-8, a toe-plate t provided with a. bridge 5 for a toe-clamp screw 6, and equipped with a pair of toeclamps 7, front andback lock bars 8, front and

back trusses

9 and 10, respectively, a pair of rear hangers 11 and a pair of front hangers 11, a rear axle 12 and a front axle 13, a pair of rear rollers 14: and a front roller 1 1, a channel-iron clamp 15, and a clamping bolt 16 and nut 17. The front and rear hangers 11 are similar to each other except in the direction of their obliquity. The two rear hangers 11 are riveted to the heellate 1, and the truss 9 extends forwardly from one of such hangers. The two front hangers 11 are riveted to the toe-plate 4, and the truss 10 extends rearwardly from the front hanger which is on the opposite side of the skate to that where is located the rear hanger from which extends the truss 9.

The toeplate 1 and the heel-plate 4 have overlapping, slotted, instep parts through which the bolt 16 passes, and adjacent terminals of the

trusses

9 and 10 overlap without touching and are received in the clamp 15 which ts such truss terminals from below. The bolt 16, after passing through the slotted portions of the toe-plate 1 and the heel-plate 4, extends downward between adjacent terminal parts of the

trusses

9 and 10, and through the bottom of the clamp 15, to receive beneath said clamp and the nut 17 It is by means ofthe parts and'members just described that the longitudinal adjustment of the skate is effected, and the sliding members secured after adjustment.

The skate thus briefly described is old and well known, and I make no claim thereto.

I will now take up in detail the new features.

There is in each hanger 11 alongitudinal slot 18 having at its base lateral extensions 1919. Hanging down from the top of each slot 18 into the same is a tongue or lug 20. filidingly mounted in each slot 18 is a block 21 in the lower portion of whichis an open ing 22 for either the axle 12 or axle 13. Each block 21 is provided on top with a lug 23, and the ends of the intermediate portions of said block as a whole are slotted to form grooves 242el in which are received the longitudinal edges of the slot 18 in which the block is located. The grooves 241 exceed in width the thickness ofthe portions of the hangers 11 which are received in such grooves, so as to provide for some lost motion laterally between each hanger and the block therein. Spiral springs 25 are inserted in the slots 18 between the tops of said slots and the blocks 21, such springs being held against lateral displacement by the

lugs

20 and 23, and the lost motion just referred to is provided to enable a certain amount of rocking motion on the part of the skate to take place without tilting the rollers 14:. The springs 25 take the weight of the skate and its load, as will presently be more fully explained, and since the bases of said springs bear on the blocks 21 and the latterare normally in the slots 18 above the recesses 24, it is plainly to be seen that the hangers 11,

, which bear on said springs, can be tilted laterally, to the extent permitted by the grooves 24:, without affecting said blocks through which the

axles

12 and 13 pass. The maximum breadth of each block 21 is approximately equal to the distance between the extreme ends of each pair of recesses 19, and the lower portion of such block, which is narrower than the part above and has therein the axle opening 22, has a longitudinal slot 26 therein which opens through the bottom thereof.

In assembling, each block 21 is introduced into the recess 19 below the slot 18 in which said block is to operate, the bottom part of the slotted and recessed portion of the hanger 11, in which said recesses and slot are located, being received in the block slot 26. Thus, said block is located at the extreme bottom part of the open portion of the hanger and sufficient space is left between the top of the slot 18 in said hanger and the top of said block for the introduction of one of the springs lVithout some provision of this kind it would be very diflicult to compress the spring sufliciently to get it into its slot and around the

lugs

20 and 23. The springs 25 are all introduced into their slots, while the blocks 21 are in their extreme low positions, and then the '

axles

12 and 13 are inserted in place, said axle 12 being passed through the two rear blocks while the latter are raised sufficiently, against the resiliency of the two springs above, to enable said axle to clear the rear hangers 11 while being passed through the openings 22 in said blocks, and similarly the front blocks are forced upwardly and the axle 13 is inserted therein. Upon the release of the parts the

axles

12 and 13 are forced down by the springs 25, acting through the medium of the blocks 21, onto the bottom edges of the open portions of the hangers 11, and there they are normally retained, such edges still being in the lowermost portions of the slots 26, but said blocks being now raised into the slots 18 with the longitudinal edges of such slots in the grooves 241.

l A spacer sleeve 27 is placed on the axle 12 between the two rear blocks 21, and the two rear rollers H are mounted loosely on said axle where they are held against axial movement by means of two collars 28 on said axle between adjacent sides of said blocks and the hubs of said rollers, and two nuts 29 screwed on to the ends of said axle outside of said rollers. 7

Unlike the rear rollers lat which are mounted outside of the rear blocks 21, the single front roller let is loosely mounted on the axle 13 between the front blocks 21. There are collars 28 on the front axle between adjacent sides of the front blocks and the hub of the front roller, also a pair of nuts 29 on said axle outside of said blocks.

The rollers are capable of rotating freely on their axles, which latter have no motion of themselves.

As already observed, the load which the rollersl l and the

axles

12 and 13 carry is supported on said axles and the blocks 21 by the springs 25, consequently as the load varies in the act of skating said springs are compressed and expand thereunder, the hangers 11 sliding in the grooves 2l,iwith the result that all shock and jar are absorbed by said springs, instead of being transmitted to the foot to which the skate is attached, the movements are facilitated and rendered more pleasurable as well as comfortable, and the aforesaid act is enhanced generally. When the springs 25 are compressed in the act of skating or under the weight of the person standing upon the skate, the bottom edges of the open portions of the hangers 11 pass below or move away from the axles. The rocking motion incident to the greater compresslon of the springs on one side of the skate than on the other has already been mentioned, and it has been explained how such motion can occur without tilting the rollers.

Changes in the shape, size, and construction of the skate in general, other than those hereinbefore pointed out, and of the new features, may be made without departing from the nature of my invention.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, in a roller skate, with the frame of such skate, such frame consisting in part of slotted hangers, of blocks slidingly mounted in said hangers, axles mounted in said blocks, the latter being cut out to permit said axles to bear on the closed bottoms of the hanger slots, resilient members arranged to force said axles normally against said closed bottoms, and rollers mounted on said axles.

2. The combination, in a roller skate, with the frame of such skate, such frame consisting in part of slotted hangers, of blocks slidingly mounted in said hangers, axles mounted in'said blocks, the latter being cut away to permit said axles to bear on the closed bottoms of the hanger slots, resilient members in said slots above said blocks and adapted to force the latter downwardly and normally to cause said axles to bear on said closed bottoms, and rollers mounted on said axles.

3. In a roller skate, a hanger apertured to form an underneath bearing for an axle, a block for the axle, such block being arranged in sliding relation to saidhanger, and cut out at the bottom to clear said bear- 1g and permit the axle in the block to bear thereon, a resilient member bearing on said hanger and on said block, and an axle receivable in said block and bearing and normally retained by said resilient member, acting through said block, in said bearing.

4. The combination, in a roller skate, with the frame of such skate, such frame consisting in part of slotted hangers, of blocks arranged to slide in the slots in said hangers, such blocks being grooved to receive the longitudinal edges of said slots, resilient members interposed in said slots between the tops thereof and said blocks, axles mounted in said blocks, and rollers mounted on said axles, the arrangement of parts being such that the bottoms of said slots ride away from said axles when said resilient members are compressed.

5. The combination, in a roller skate, with the frame of such skate, such frame consist ing in part of slotted hangers, of grooved blocks arranged to slide in the slots in said hangers, the longitudinal edges of said slots being received in the grooves in said blocks, and each of said grooves being wider than the thickness of each of said edges, resilient members interposed in said slots between the tops thereof and said blocks, axles mounted in said blocks, and rollers mounted on said axles.

G. In a roller skate, a hanger having a longitudinal slot therein with lateral recesses at the base thereof, and a bearing and guide block receivable in the recessed portion of said hanger and slotted to receive that part of said hanger which is below the open portion thereof, said block also being grooved to receive the longitudinal edges of said slot, and per orated to receive an axle.

7. The combination, in a roller skate, with the frame of such skate, such frame consisting in part of hangers, of a block arranged in sliding relation to each of said hangers, a resilient member interposed between each of said hangers and its block, axles mounted in the blocks, rollers mounted on said axles, and means to provide lost motion laterally between each of said hangers and each block, whereby said frame may be rocked laterally without tilting said rollers.

8.
