F- R. SMITH ROLLER SKATE 7 Jul 5, 1932.

Filed June 19, 1951 Patented July 5,1932 M p; i


Application filed June 19,

My invention relates to improvements in roller skates and more particularly to ball bearing roller skates.

The primary object of the invention is to provide a skate wherein the Wheels are sectional and contain ball bearings which permit less friction during the use of the skates, and the mounting of a resilient tire on the wheelsto insure a minimum of shocks to the user when the skates are in motion.

Another object is the novel construction and the easy running qualities Obtained by the use of the spring leaves in conjunction with the single wheels forward and back and 5 their forked arms. I u e Other objects will be apparent from the following description in connection with the accompanying drawing which. illustrates the mechanical features of the skates, and in which: n

Fig. 1 is a side elevational view with the frame of the skate insection.

Fig. 2 is a vertical transverse section taken on line 22 of Fig. 1.

Fig. 3 is a section taken on line 3-3 of Fig. 2;

Fig. 4 is a section 011 the line 44 of Fig. 1. Referring to the drawing: the heel plate is noted at 10 riveted at 11 to a foot spring 30 plate 12 and at 9 to a leather heel support 8 which fits between theplate 10 and the foot 7 said foot plate being cut out at 13 to form an aperture 14 and the cut out portion is bent downward forming a flange 15. 35 12 is bent in such manner as to form a rise 16 just back of the ball of the foot 7;which' 45 at opposite ends and extending atan angle ing a unit.

The plate 1931. Serial No. 545,431.

from said plate 25 and areintegral with the a plate. Mounted between the arms 29 and 30 are the wheels, each of which consists of a shaft 31, flattened at each end 32 and 320;,

said ends being threaded to receive the nuts 33 and 33a; on each shaft is a cone'shaped bearing race 34, ball bearings 35 and bearing cups 36 and 37 which have countersunkapertures 36a and 37 a in their outer surfaces into which a felt,leather or rubber washer 38 is fitted. Bearing cup 36 is threaded at 39 to be turned into the bolted flange 40, the bolts 41 I i being inserted through the flange a and the wheel discs 42 and 42a and the center supporting plate43 and the bolt flange 40 thus form- When the wheel isassembled and bolted together the prongs 29 and 30 are slipped over eachend of the shaft. 31 and held in position by the nuts 33 and 33a. 3 The disc 40 and 40a have at their periphery rims 44 and 44a with a peripheral tire seat or groove 45 in which a tire 46 is mounted being cast upon the center supporting plate 43. f A toe clamp 47 of the usual kind is carried by the forward section of the foot plate 12 andan instep strap or heel support 8 is riveted to the heel plate 10.

When the body is resting fully upon the skates the weight flattensthe springs 22'and 23'slightly and thus spread the wheels fur ther apart giving a resilient spring like motion when in user i a I claim:

V 1. Arollerskatecomprisinganupperspring foot plate, a lower, upwardly bowed, springplate clampedto the under side of the foot plate, said lower plate having a fork at each end, anda wheel supported in each fork.

2. A roller skate as in claim 1, and a reinforcing spring plate fixed to the under side of the foot plate and resting upon the lower plate. t r

3. A roller' skate as in claim 1, the foot;

plate having a longitudinal flange depending therefrom beside the lower plate.

4. A roller skate comprising an upper foot plate, a reinforcing spring plate fixed to the 5 under side thereof, a convex spring plate on topof which the reinforcing plate rests, an adjustable clamp extending around all of said plates, the convex spring plate having forks at the ends, and a wheel in each fork.


In testimony whereof, I do affix my signa- E NK R; M I I
