The object of the present invention is't-o provide askate of this general type having relatively large wheels yet withja lowfcentre I '7 of'support, which is economical in manufac- 9 ture, and which is oflight, rigid and durable construction. Y

With these objects in view, the present invention consists in the skate hereinafter [de-c scribed and particularly defined in the claims. r

. Having ,thus describedjthe invention", what I isclaimedis: 1

l. A skate comprising an integral frame having a horizontal sole plate, a vertical; red inforcing rib for the sole plate and integral therewith throughout the length of the plate,

skate as applied to a shoe; Fig. '2 is a bottom plan view of the skate; and Fig. 3 is a section on line 3-3 of Fig. 2. I I The illustrated embodiment of the inven- 7 tion comprises a skate having a frame or foot-supporting portion indicated generally at 4, on which are mounted wheels 6 at opposite ends thereof and in the longitudinal median plane of the foot. The frame is adapted for attachment toa shoe 8'of any desired a form, by means of rivets. I

The frame comprises an integral casting, preferably a die casting, It consists of'a sole plate 10 for engagement with the sole of the shoe, andthis plate is'considerably narrower than the shoe to which it is to be attached in order that it will not strike upon thesura face of the ground when theskate is inclined] V to one side or the other,-either. in straight "away speed skating or in making abrupt changes of direction. A longitudinal medial, vertical reinforcing rib 12 is formed on the t frame for the purpose of lending strength to the entire structure, while'permitting manufacture of the skate from material of light weight, such as is usually employed in the die casting art. At each end of the skate is a yokeil lwhich extends upwardly and longitudinally from the frame, being formed as a continuation of the reinforcing rib 12. The wheels arejournaled in the ends of the yokes and by the upward curvature of the yokes as w illustrated in Fig. 1, the center of gravity both ends of the ing integral frame having a sole plate adapt andyokes extending upwardly and longitudinallyfrom the sole plate and rib 011 frame and lying wholly above the lowermostpoint of the rib, and

wheels jounaled in the yokes.

2. A skate comprising a rigid and unyield,

ed for attachment to a shoe and of, less width than thatof the shoe to which it isto be attached, and yokes formed integrally with the sole plate and extending upwardly and outwardly from opposite ends of the soleplate, 59

.the plate at each end overlying and merging into the yokes. v

3; A skate comprising an integral casting having a sole plate and a medial, vertical,

yokes and wheels journaled in the I reinforcingrib,'the rib being extended longitudinally at opposite ends of the soleplate it i to formyokes, the yokes extending upwardly with their, free endslocated a substantial dis- A tance above the sole plate, and wheels journaled in the yokes.

4. A skate. comprising a rigid integral casting having a sole plate, a vertical reinforcing rib below the sole plate, yokes formed integrally with the sole plate and the rib 9 A and extending outwardly and upwardly from opposite ends thereof, the sole plate at each end merging into the yokes adjacent the rib with the top surface of the plate coincident with the top surface of the yokes at the point 1 of merger, the yokes being of a width at least as great as that of the rib, and wheels journaled in the yokes, the center of gravity of the skate being below the axis of rotation of 5 the wheels.

5. A roller skatehaving but two wheels arranged one in front of the other, a rigid foot-support located between said wheels and located in a plane below a plane assing through the centers of the said whee s, said foot su'pport being-formed lon tudinally to resent an up er surface whic is lower adacent to the ront Wheel than it is adjacent to the rear wheel thereb to conform substantially with a foot of t e wearer and yokes extending from the foot-support and attached to the wheels to support said footsupport between them.

6. A roller skate having afoot-su porting 29 plate, a reinforcini rib below said oot-suporting plate, yo es extending upwardly rom beneath the ends of the foot-supporting gate and having wheelsqournaled n their ee ends, the centers ot saidwheels being 533 located substantial distances above the plane of saidffoot-supporting plate.

I In testimony whereof I hereunto sign my name to thissgeeification. n URNHAM e. PRESTON.
