The leather layers l2 and I3.

therefore, the skate elements 6 and are designed to give more elevation to the heel tion of the foot. Each of said skate elements 6 and i is comprised of a longitudinal plate M which is fastened by rivets |5 to its plate.

lindrical stud it? having a screw-threaded hole |1 therein and which is provided, for strengtheningpurpo'ses, with webs Hi and IS. A long screw 26 is screw-threaded in the stud l6. Immediately below the stud I6 the screw passes through the front end of a leather strap 2|, and beneath this there is a lock nut 22 on said screw 20. Beneath the lock nut 22 there is a metal washer 23 adjacent to an annular rubber cushion 24, beneath which there is located a perforated car 25 integral with a T-shaped cylindrical bracket 26, through which an axle 21 passes to support a pair of front rollers 28 and 29 in the same way as a pair of rear rollers 30 and 3| Beneath the car 25 there are a rubber washer 3|a and a metal washer 3|?) adjacent to the head of the screw 20. Screw-threaded on the axle 21, at each end of the T-shaped bracket 26, there is a nut 32 for holding the axle 21 tightly in the bracket 26. Outside of the nuts 32 there are carried the wooden skate rollers 28 and 29, which are provided with two annular ball races 33 and 34 provided with circular sets of balls 35 and 36 to provide ball bearings, the balls of which are retained in place by the nuts 32 on the inner faces of the wooden rollers 28 and, 29 and nuts 31 onthe outer faces thereof, which are also screw-threaded to the axle 21. Lock nuts 38 on the ends of the axle 21 hold the nuts 31 in locked position. Furthermore, the T-shaped axle bracket 23 has a diagonal arm support 39 which extends upwardly and is provided with a short pin which passes into a rubber washer 4| which is supported upon an inclined projection 42 forming a part of the plate 14 and which is provided with a hole 43 to receive the short pin 48. As shown in Fig. 7, the strap 2| may beprovided with a front hole 44 and a rear hole 45 for connection with the two skate elements 6 and. 1 described above.

However, as shown in Fig. 6, instead of the strap 2| I may provide a turn-buckle rod 46 having at the two ends thereof screw-threaded rods 41 and 48 which have, respectively, spherical heads 49 and 53 to be received in universaljoint sockets 5! and 52, which have screwthreaded thereon annular retaining caps 53 and 54. Nuts 55 and 55 on these rods'41 and 48, respectively, have, together with said rods 41 and 48, right and left-hand screw-threads to cooperate with a similarly screw-threaded turnbuckle 51. Also, in this instance there are shown leather washers 58 between the nuts 22 and the metal Washers 23 to compensate vertically for the thickness of therubber washers 4|, and maintain the desired angularity of the diagonal support 39. V

In the operation of my invention, it will be understood that the shoe particularly the solev or pad 2 thereof, is not only provided with a considerable degree of elasticity, due to. the packof the foot than is provided at the front por- Fur- V thermore, formed on the plate Hi there is a cy-.

4 ing 3 and the rubber or other elastic material enclosing the said packing 3, but is also capable of considerable torsional movement, respectively, between the front and rear ends of the pad on a horizontal axis. In skating with the skates constructed'in accordance with my invention, :7 are mounted on a yieldable mounting so that when the foot is depressed at one side of the skate,

this will cause a turning of the axle 21 in a horizontal are on the inclined axis of the arm 39, thus giving turning movement to the skate. In addition thereto, in the skate made in accordance with my invention, various other movements are effected while skating. For instance, the turning movement referred to astaking place at the front of the skate can be different from' the turning'movement attained by the rear. of the skate, due to the torsional flexibility of the shoe and pad 2 simulating the torsional movement of the respective parts of. the foot normally. Also, a very important movement of which my skates are capable is that the two skate elements 3 and 1 may move laterally'as a whole with regard to each other, even without a turning movement, due to their independent mounting and the flexibility of the shoe I and pad 2. different portions of the two skate elements 6 and 1 are capable of different relative elevations from the floor, while, supported from the latter; Also, the two elements are, furthermore, capable of relative rotation as a whole on horizontal;

transverse axes of the foot above the axles 21, due to the bendability of the pad 2. Likewise,

the two elements 6 and 1 are capable of moving" towards each other as a whole, due to thefiexibility of the strap 2| and to the loose connectionof the turn-buckle bar 46 therewith. In the case of the leather strap 2!, the two elements 6 and 1 are capable of slight relative movement as a whole away from each other longitudinally, due to the elasticity of the strap. Also, it will be noted that the noise in skating is greatly reduced by reason of the skate elements 5 and 1- not being mounted on a single plate'to act asv a sounding board, but, instead, are mounted on the yieldable pad 2 of the shoe. The elimination of the noise is further greatly aided by rea son of the rubber washers SM and the rubber washers 4 I in that it will be noted that the axles 21 and T-shaped brackets 26 in which they are carried are effectively floated on theyielding,

elastic, rubber cushions 24', 3|a, and 4| from the' plates l4 and the plates 8 and it, which in turn are supported upon the elastic pad 2 comprised of a casing of elastic rubber or other similar materials enclosing the elastic packing of cot-f ton linters or fibrous material.

In skating with the'said skates, it is found that on account of the fact that'the skate freely and effectively accommodates itself to the unevennesses in the floor, a better traction is obtained between the skate and the floor, thus per- Furthermore, for similarreasonsthe' of the foot while applied to the skate. Besides, the skating equipment is light in weight, notwithstanding the flexible and elastic qualities thereof, because of the use of the packing in the pad 2 which eliminates the necessity oi heavy thick, rubber soles. In other words, thesole, comprising the pad 2, is as elastic a-S rubber, but much lighter. .Also, the sound in skating is practically eliminated becausethe rollers 28, 29, 3i, and 3| are practically floated on rubber supports and, besides, are not connected together by any unitary plate to act as a sounding board. The self-alignment feature also conduits to thee) sence of noise. In effect, the skatesmade in accordance with my invention avoid bindingthe foot to what amounts to a splint, which was previously necessary with the skates, as hitherto made. In skating with my skates, thus, theskate in reality moves with and is capable of substantially the same motions as the foot in its natural movements.

While I have described my invention above in detail, it is to be understood that many changes may be made therein without departing Irom the spirit of the same. For instance, in my skates, a correct mounting thereof of the sole can be attained as the respective elements can be placed directly beneath the ball and heel of the foot, respectively. Also, the inclinations of the two studs 16 can be made differently to the ball and heel of the shoe, respectively, according to the angle of the supporting sole portions, so as to attain different turning. movements thereby, if desired.
