ROLLER-SKATE WHEEL.

SPECIFICATION forming part of Letters Patent No. 330,554, dated November 17, 1885.

Application filed Noremher 24, 1884.

To all whom it may concern,.-

Be it known that I, GEORGEO. BoYNToN, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Roller Skate VVheel's, of which the following, taken in connectionwith the accompanying drawings, is a specification.

My invention relates to the manufacture of 1o roller-skate Wheels; and it consists in a rollerskate wheel, the body of which is made of wood and re-enforced by an endless band of leatheroid or parchmentized-paper material, whereby the wheel is greatly strengthened and rendered much less liable to split without materially increasing its Weight. A

Figure l of the drawings is a side elevation of my improved roller-skate Wheel, and Fig. 2 isa section on line x x on Fig. l.

2o In carrying out my invention I iirst turn the wooden body A nearly to the form shown in the drawings', with its periphery slightly crowning, or larger in diameter in the center of its length than at its two ends, and with a hole through its center considerably larger than the diameter of the axle upon which it is to be mounted, and counterbored upon each side to have an annular recess surrounding said central hole, as shown in Fig. 2. I then take 3o a section of a tube of leatheroid or parchmentized-paper material of an interior diameter slightly less than the diameter of said wooden body at its ends, soak it in water to swell it,V slip it upon the Wooden body, and let it dry,

3 5 when it will shrink into iirm contact with the periphery of the wooden body, and thus become firmly secured thereto. Bushings of leatheroid or parchmentizedpaper material C Serial No. 148,708. (Model.)

are then fitted to and firmly secured in the recesses in the sides of the wheel, said bushings having drilled through their centers the y holes a to receive the axle, which holes may be formed before or after inserting the disk in the recesses. The chamber between the bushings C C may be filled with a ring of felt, b, or other absorbent material to hold oil, or the felt or absorbent material may be dispensed with and the chamber be filled with oil; but I prefer to use the felt packing b, because there will be less liability of damage to clothing from the flying oil. The wheel is then turned and polished, when it is ready for use.

The advantages of my improved skate-wheel are greater strength due to the re-enforcing hoop, more durable wearing peripheral surface dueto the greater hardness and tough-V ness ofthe parchmentized-'paper re-enforce, a better wearing-surface upon the axle, and a convenient and sure means of lubricating the axle.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

A roller-skate wheel having secured upon its periphery an endless hoop or tire of leatheroid or other parchmentized paper solidied into a homogeneous mass Without glue, ceinent, or other adhesive paste, substantially as described.

In testimony whereofI have signed my name to this specicatiomin the presence of two subscribing witnesses, on the 21st day of November, A. D. 1884.

GEORGE O. BOYNTON.
