ROLLER-SKATE- SPECIFICATION forming part of Letters Patent No. 326,540, dated September 22, 1885.

Application filed February 14, 1885. (No model.)

To aZZ whom it may concern..-

Be it known that I, GEORGE W. BAKER, of Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and .useful Improvements in Roller-Skates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in roller-skates, having for its objectaflat spring for the support of each roller-axle, said spring being slotted longitudinally, so that its torsional action is substantially that of two springs with an unyielding depending plate passing through the slot in the spring, with laterally-projecting shoulders aboveand below the spring, and so arranged that the spring is supported by the plate and the compression, recoil, and torsion of the spring are limited thereby.

With these objects in view my invention consists in certain features of construction, and in combination of parts, hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of my improved roller-skate with one of the rollers removed. Fig. 2 is an end elevation. Fig. 3 is a view in perspective of the spring. Fig. 4 is a View in perspective of the depending plate that supports and limits the movements of the spring. Fig. 5 is a plan view of the spring before itis bent.

A represents the foot-rest; B, the spring; C, the plate that supports and limits the movements of the spring; D, the rollers, and E the roller-axles. The rollers are set in pairs,and the devicesfor holding the axles are fac-similes of each other, but reversed in position, as shown. The springs and plates 0 have each aflat corresponding part for attachment to the foot-rest, with holes, respectively, b and c, that register, so that but one set of screws is required for attaching a spring and plate, the springs lying next to the foot-rest, between it and the foot of the I plate 0.

The spring has a longitudinal slot, B, extending about the length of the yielding parts of the spring. The springs are bent approximately in the form shown, and the free ends thereof are wrapped around the central portion of the axles and riveted, holding the axles firmly.

The plate 0 is bent at about a right angle, so that it extends downward for some dis tance about perpendicular to the foot -rest, after which it is bent obliquely, as shown, so that the latter part is approximately at right angles to the adjacent portion of the spring.

A tongue, 0, extends through the slot of the spring, with shoulders 0 above and extending about flush with the edges of the spring, and narrow shoulders 0 below. The shoulders a slope upward and outward, by means of which the spring in its normal position rests only on the inner part of these shoulders. The respective shoulders 0 and c are separated far enough to allow a limited movement of the spring. When the spring is compressed by an equal pressure on the two rollers, it is supported by both shoulders c, as aforesaid. If a greater pressure is had on one roller, causing arocking movement of the axle, the spring will engage the shoulder c on the side where the greater pressure is bad. In such cases the side of the spring sustaining the greater pressure will engage the contiguous shoulders c nearer to the outer end of the shoulder, according to the pressure. These shoulders c in the central part are cut away slightly, as shown, so as not to come in contact with the rivet-heads that secure the spring around the axle. Any torsion of the spring, as would be had if one end of the axle is pressed rearward, would bring and loosely connected with the spring and arranged to limit the movements of the spring in all directions, substantially as set forth.

2. In aroller-skate, a bifurcated spring rigidly attached to the foot-rest and to the rolleraxle, a plate rigidly connected with .the footrest and extending through the slot of the spring, with shoulders on either side of the spring, and arranged to limit the movement of the spring in all directions, substantially as set forth.

3. In a roller-skate; abifurcated spring rigidly secured to the foot-rest, and the free end thereof bent around and rigidly secured to the roller-axle, a plate overlapping and secured by the same fastening as the spring, a narrow part of the plate extending through the slot of the spring,with shoulders on either side of the spring to limit the movement of the latter, substantially as set forth.

day of February, 1885.

GEORGE W. BAKER.
