M. G. :HEN-LEY. Roller Skate] No. 234,404. v Patented Nov. 16,1880.




SPECIFICATION forming part of Letters Patent No. 234,404, dated November 16, 1880,

Application filed February 27, 1880.

To all whom it may concern:

Be it known that I, M'IOAJAH G. HENLEY, of Richmond, Wayne county, Indiana, have invented certain new and useful Improvements in Roller-Skates; andI hereby declare the following to be a full, clear, and exact description of the same, reference being had to the drawings which accompany this specification,

forming a part of the same, and to the letters of reference marked thereon, in which- Figure 1 is a side elevation of the front end of the skate. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is an end elevation of the truck or wheels and frame. Fig. 4 is an inverted plan of the platform of a section of the skate, showing the metallic frame by which the trucks or wheels are attached to the platform of the skate and the devices by which it is made adjustable and detachable. Fig. 5 is a vertical cross-section perpendicular to the line of the axle.

Like letters refer to like parts.

In Fig. 1, O is the platform or foot-piece of the skate. A is the wheel. B is the axle, and Gr G is the gallows-frame which constitutes the hangers or supports for the axle B.

L L are supports secured to the foot-piece of the skate, as shown in Fig. 2, the inside surfaces of which are at a suitable angle to the plane of the foot-piece O, L being the shorter and placed at the ends of the same, while L is constructed with an angular top plate, Z, forming the upper portion thereof, having an inclined horizontal plain surface.

The set-screw D passes through an opening in the lower portion of the support L, which opening is provided with a thread, in which the screw D is operated, said screw passing into the cap of the gallows or hanging frame G and resting in a recess therein, by which the point of the screw D forms a pivot, allowin g the foot-piece O a rocking motion laterally. The screw D is provided with a jam-nut, a, fitting the thread of the same, and which works against the outer surface of the support L, thus securing the screw D rigidly .in its position.

The cap of the frame G, and which forms the bearing of the same, is constructed with its upper surface in an angle parallel with the angle of the top plate, Z, of the support L, and

forms the bearing for the spring E and the plate F. The plateF is made in nearlya square form, and is intended to move freely up and down between the inside surfaces of the supports L L, and is provided with a lug which receives the point of the screw M. It acts as a pressure-plate when it is operated by the screw M in regulating the tension of the spring E.

The plate F is provided on its opposite surface with a spur or any other suitable device, to hold the spring E, with which it is in direct contact, in place. The spring E, which is of rubber or any other suitable material, is of the same general form and size as the plate F,- by which it is operated through the action of the screw M, by which a greater or lesser density is communicated to the spring, thus accommodating the skate tothe weight of different persons using the same, as well as to regulate the flexibility of the lateral motion of the same. The screw M is let into the foot-piece of the skate by an opening in the same at an angle in the direction of the plate F upon which it rests, and is held in place by the operation of its thread in the support L.

The cap of the gallows or hanger frame G is provided with recesses on its front and back surfaces. fitted to receive the screw D on one side and the lug H of the support L on the other, permitting the lateral or rocking motion of the foot on the gallows-frame and wheels.

The wheels and axles are of the common form, and may be made of any desirable size, and any of the ordinary or well-known devices used for holding the wheels in place on the axles may be employed.

It will be seen that by removing the setscrew D the cap of the gallows-frame G, with its attachments, is readily removed and the wheels or trucks disconnected from the platform or foot-piece G, as shown in Fig. 4.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The plate F, when arranged to move free ly between the inside surface of the supports L L, and provided with a lug to receive the point of the screw M, the said plate being of a rectangular form, and in its operation serv ing as a pressure-plate when operated by the the supports L and L, the set-screw D, and screw M, regulating the tension of the spring jam-nut a, all arranged and operating in the E, with which it is combined, and which is armanner and for the purposes as described.

ranged, as described, to hold the spring E in 4. The combination of the screw D, lug H,

5 place. and gallows-frame G, when operating in the v5 2. The adjustable plate F and the screw M, manner and for the purpose as described. in combination with the spring E and foot- MIOAJAH O. HENLEY. piece 0, as and for the purposes set forth and Witnesses: described. I. T. DENNIS, 1o 3. The gallows-frame G, in combination with SAUL (J. DAVIS.
