' WALTER WARE, OF CHICAGO, ILLINOIS.
ROLLER-SKATE.
1 .dtlldhllidd.
To all whom/it may concern:
Be it known that I, WALTER WARE, a] citizen of the United States, residinr at Chicago, in the county of Cook and gtate of Illinois, have invented a certain new and useful Improvement in Roller-Skates, of which the following is a specification.
My invention relates to roller skates, and
the objects are to strengthen the skate and a socket 4 for receiving the ball til simplify the construction thereof. These objects are obtained by the mechanism and structural expedients shown in the accompanying drawings, in which:
Figure 1 is a side view of'a skate embodying the invention, a portlon belng shown in vertical central section.
\ Fig. 2 is a bottom plan view, a portion of one of the axles and associated parts being removed to better reveal-the construction.
Fig. 3 is a ing, and
Fig. A is a perspective view showing a fragment of the hanger to illustrate the ball and socket form of joint.
Similar numerals refer to similar throughout the several views.
The shoe plate 1 may assume any convenient form and is adapted to be fastened to the shoe of the user. In the present case it consists of sheet metal and has marginal ribs 2 for strengthenin it. the underside of this p ate are two plates They are duplicates of each other and preferably made of cast metal. Each has 5 formed at the upper end of the han er stem 6. The hangers also are prefera ly of cast metal and are duplicates of each other, and each is provided at its lower end with an axle 7 on which the wheels or rollers 8 are mounted. A platform 10 is formed upon each hanger for supporting a cushion 11 which is interposed between the platform and the boss 12 formed upon the companion frame 3. A stud 13 passes freely through a suitable aperture in platperspective view of the trussparts form 10 and also through the cushion 11' and screws into the boss 12 for holding the parts assembled as best shown at the left hand of Fig. 1. By preference, cushion 11 is cylindrical an provided at its upper end with a pressed metal cap 14. It is 7 made of rubber or other resilient material.
The parts are so constructed that the stem 6 of the hanger extends obliquely upward Specification of Letters Patent;

from the axle and outward toward the end of the skate," while the stud 13 extends from a point near the axle obliquely upward and inward toward the middle of the skate. The stem and the stud are approximately at right angles to each other. The socket 4 and 'ball 5 at each end of the skate constitute a ball and socket joint and the result is that the stems 6 of the hangers constitute, in effect, axes which permit the hangers to turn slightly, in response to the variations in pressure by the foot of the user upon the familiar roller-skate principle. To illustrate, when the user throws his weight to the ri ht side of the shoe plate, the front axle wi 1 turn slightly to the right and the rear axle slightly to the left, thus causing the skate to curve to the right. The movement for never very great and the cushions are sumciently resilient and yielding to permit it.
The ,screw studs are connected to the hangers loosely enough to permit them to make their necessary movement, but at the same time afiord adequate means for holding the parts assembled with the balls 5 in the sockets 4.
Roller skates are usually weak in the middle. In the present construction, however, the skate is extremely strong at this point and the added weight of material is inconsequential. This advantage is obtained in the following manner:
A shoulder rivet 16 shoe plate 1 near the middle and against the shoulder of the rivet at the bottom bears a flat bar 17. This bar is riveted at the ends to feet 18 formed at the inner ends of the plates 3. A brace 20 is riveted to the underside of the bar 17 at rivet 16. The outer ends of this brace have partially upturned feet 21 which. are apertured to accommodate the studs 13. They bear against the bottom of the bosses 12 and are lock nuts 22. This results in the formation of a very strong truss which acts as a most efiective reinforcement at the middle of the skate. It will be noted that the feet 21 engage the bosses 12 upon a plane almost transverse to the leg of brace 20 which lies between the riivetand the boss. In other words, there is a firm abutment for the end of the brace 20, and this abutment is faced in a direction advantageous in resisting the tensional strain in the brace. A force exerted downward this purpose is is fastened to the at the middle of the skate would put rivet 161 undercompression and would put both comparatively the brace and the bar 17 under tension, and hence there is a true trussing efiect.
The operation will be readily understood from the foregoing. As the user swings his weight from one side of the skate to the other he causes compression in one side or the other of the cushions 11 and a corresponding rotation of the balls 5 in the socket 4. This ermits the axles to turn to the rightor eft, as required.
The parts are few in number and are simple in form and yet they afi'ord great strength. Furthermore, the cost of manufacture is reduced by thus using duplicate plates 3 and duplicate hangers at each end of the skate.
Having thus described my invention, what I claim as'new and desire to secure by Letters Patent, is:
In a roller skate, a shoe plate, wheel and axle supports at the ends of the shoe plate respectively, a bar spaced from the under side of the shoe plate and having its central portion connected to said plate and its ends secured to the supports respectively, and a brace having its center secured to said bar and diverging portions extending away from the shoe plate and terminating in angular disposed ends secured respectively to the supports.
In witness whereof, scribed my name.
I have hereunto sub- WALTER WARE.
