No. 253,735. Patented Feb. 14,1882.
JXM/ WQJ Y UNITED STATES PATENT OFF-met CHARLES E. MARS-HALL, OF BOSTON, .MASSAGHUSETTS, ASSIGNOR TO HIM- SELF AND GEORGE N. PARKER, OF SAME PLACE.
SPECIFICATION forming part of Letters Patent No. 253,735, dated February 14,1882.
Application filed August El, 1881. (No model.)
To all whom it may concern:
Be it known thatI, CHARLES E. MARsHALL, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Roller-Skates; and I do hereby declare that thefollowin g is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and .the construction of the skate, so that it will be strong, durable, and light to the feet of the wearer, and to render the rollers and axles selflubricating, whereby they will work with much greater ease and comfort to the person wearing them. These several objects I attain by the construction, substantially as shown in the drawings and hereinafter described.
In the accompanying drawings, A represents the sole-plate, formed by molding or pressing itout of paper-pulp, and has connected thereto the usual fastenings, a I), for securing it to the foot of the wearer.
To the heeland toe of the sole-plate A are secured metallic boxes 0, for containing rub-' her or other elastic cushions d. To these boxes 0 are hinged or pivoted the hollow axles B, each axle being formed with a frame or seat, 0, for the lower end of the cushions d, said seat being inclined in opposite directions, so
as to secure the entire elasticity of the cushions when the skater is turning a curve, and insuring the cushion being retained in place.
The seats 0 are each formed with an eye, 6, through which passes a pin, f, the ends of the pin entering the sides of the boxes 0, thereby securely connecting the axle B to the boxes, and enabling the sole-plate A to have the required rocking motion. The axles B are-made hollow to receive oil or other'lubricant, the same being introduced through an opening which is closed by a screw, 9, on a suitable plug. The lubricant works out through small holes h, near the ends of the axle, and onto the outer periphery of the same, thereby automatically lubricating itself.
The rollers D, like the sole-plate A, are formed from paper-pulp, the object thereofbeing to make the skate as light as possible to the feet of the wearer, thereby enabling the person to skate with less exertion and much longer without tiring. A skate with paper sole-plate and rollers increases its lightness to such a degree as to render the skate especially adapted to ladies and children. The rollers D are provided with metallic bushings i, and between these bushings and axles are a series of round bars, k, encircling the same, as shown in Fig. 4, thereby insuring the easy running of the rollers D with comparatively little friction.
The sole-plate A, I- prefer to make of the form shown,a concave or curve in the sole and toe portion and the surface of the heel portion on a line below the lowest part of the surface of the sole, as illustrated in Fig. 1, this being considered the most comfortable and easy'shape for the sole-plate to the skater.
Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A skate provided with a sole-plate com posed of paper, substantially as and for the purpose set forth.
2. In a roller or parlor skate, the combination, with the, usual sole-plate and axles thereof, of suitable rollers composed of paper, substantially as and for the purpose specified.
3. As an improved article of manufacture, a roller for parlor-skates, composed of paper, substantially as and for the purpose described.
4. In a roller or parlor skate, the axle B, cast with seats 0 inclined in opposite directions, as shown, and a central eye, 0, in com- 5 bination with the elastic cushions d, disposed upon each side of the eye 0, the latter being pivoted to the box 0 by pin f, substantially as and for the purpose set forth.
5. In a roller or parlor skate, the oombinatoo tion, with the axleB and roller D, having the In testimony that I claim the above I have metal bushing i, of the round bars 70, loosely hereunto subscribed my name in the presence retained around the axle and between it and of two witnesses.
the bushing by suitable disks or plates 0on- (JHARLES E. MARSHALL. nected to the axle upon the inner and outer Witnesses: sides of the roller, substantially as and for the JOHN G. MlLLER,
purpose specified. N. A. THOMPSON.
