[EDWARD J. COX, OF RAVENNA, OHIO.
ROLLER-SKATE.
SPECIFICATION forming part of Letters Patent No. 243,761, dated July 5, 1881.
O Application filed April 7, 1881. (No model.)
To all whom it may concern Be it known that I, EDWARD J. Cox, of Ra.- venna, Portage county, Ohio, have invented a new and useful'Improvement in Roller-Skates, of which the following is a specification.
The nature and object of my invention is a roller-skate, in which the axle of each pair of rollers is supported by an ihclined hanger whose upper end is pivoted to the bottom of the footplate, and the lower end supported between two rubber springs by a screw-bolt in a rigid hanger attached to the bottom of the footplate.
In the drawings, Figure l is an elevation. Fig. 2 is a vertical longitudinal sectional view through the center of the foot-plate. Fig. 3 represents the inclined hanger of a pair of rollers. Fig. 4 is a section, on an enlarged scale, at the dotted line in Fig. 2.
The bottom of foot-plate a is recessed at a near each end. Each pair of rollers b rotate on shaft 0, which is supported by the inclined hanger d. The upper end of hanger d is pivoted through lug e and rubber spring to by pinfin recess a to plate a. Below shaft 0 hanger d has a perforation, 6, through which it is bolted between two rubber springs, 12 n, by screw-bolt 0 to the rigid hanger 9 attached to the bottom of plate a. The springs to and a slightly yield to the stroke of the rollers on the floor, and thus lessen the noise and prevent a sudden jar to the skater. Hanger g has a flange, h, at its lower end, to retain rubber spring a in position. The perforation i of hanger d is countersunk on both sides of the hanger, to allow the latter to turn on its pivot f. The rubber spring n is compressed on one side by tipping foot-plate a when moving on a curve.
When a person using the skates is moving in a curve the greater weight on rollers b at the side of plate a which is tipped down compresses each spring a n on the opposite side from the other. and turns the inclined hangers d on their pivots f. The center of the axis of shaft 0 is in line with pivot f, and the directions of shaft 0, pivot f, and screw-bolt 0 are at right angles to each other. Each hanger d turnsin the opposite direction from the other by reason of their being convergently inclined. When the pressure of the foot on plate a restores it to a horizontal position, the reaction of the compressed rubber springs n n turns hangers 01 back again to aposition in which the rollers b will move in a straight line.
The roller-shaft c has its hearings in the outer arms, 11, of hanger d, and also in the central part of thehanger, which is bolted through springs a n to hanger 9.
Roller 12 has a circumferential groove, 00, at the middle of its face, in which is placed the rubber ring 8, a cross-section of which is circular. This ring is solid, to give it firmness, and it extends but slightly beyond the circumference of the roller, that the weight or pressure on plate a may compress ring 8 entirely within the groove and allow the whole width of the roller-face to be in contact with the floor.
The purpose and function of the rubber ring 8 is to lessen the noise of the rollers by preceding them in contact with the floor, and also to prevent lateral slipping of the rollers on the floor. V
I claim as my inventio n 1. In roller-skates, the inclined hangers d, converging downward, and each beingpivoted at its upper end to the foot-plate a, and provided with the countersunk perforation z'at its lower end, and with rollers I) and shaft. 0 intermediate the perforations and the upper pivot, in combination with two rubber springs, n a, screw-bolt 0, and rigid hanger g, the springs n n being on opposite sides of hanger d, and the screw-bolt o passing through the springs and countersunk perforations into the rigid hanger, substantially as and for the purpose described.
2. In roller-skates, the inclined hangers d, pivoted at their upper ends to the foot-plate a, and provided with rubber spring w between the hanger and footplate, in combination with rollers 1), rubber springs 00., screw-bolts o, and rigid hangers g, substantially as described.
EDWARD J. COX.
