FFIQIIO JOSEPH N. STERLING 'OF SPRINGFIELD, OHIO.
ROLLER-SKATE.
SPECIFICATION forming part of Letters Patent No. 346,512, dated August 3, 1886.
Application filed January 6,1886. Serial No. 187,793. (No model.)
of Ohio, have invented certain new and useful Improvements in Roller-Skates, of which the following is a specification.
My invention relates to improvements in roller-skates; and theobjects of my invention are, first, to provide a novel and simple construction by which the supporting wheels or rollers may be readily detached from the body of the skate for oiling or cleaning; second, to provide a skate in which the tension of the I 5 elastic cushion of the front and rear truck may be easily and uniformly adjusted by a common adjusting device, each of said trucks being also capable of an independent adj ustment, so that a uniform adjustment may be secured at the same time the different trucks maintain a diiferent tension; and, third, to provide a connection of novel construction between the respective trucks and the foot-piece, whereby the elastic cushion is adapted to form a spring or cushion for the foot-piece without materially affecting the tension of said cushion.
My invention consists in the various constructions and combinations of parts, herein,-
0 after described, and pointed out in the claims.
In the accompanying drawings, which form a part of this specification, Figure 1 is a side elevation view of a skate embodying my invention. Figs. 2, 3, and 4 are a side, a sec- 5 tional, and a rear elevation, respectively, of
one of the trucks and its attachments. Fig. 5 is a side elevation view of the same, shown partly in section. Fig. 6 is a sectional elevation of one of the trucks, showing a modification of Figs. 7 to 11, inclusive, are detailed views of the cushion and connecting mechanism. Figs. 12 to 14, inclusive, are views of the detachable rollers, and Fig. 15 is a detailed view showing a modi- 5 fied form of the independent tensionadjustment.
In the said drawings, A represents the top or foot plate of the skate, and B B the rollers, which are constructed in the usual manner.
Each of the trucks is hinged to a frame, 0,
at an angle to the foot-plate A, so that an oscillation of the truck in either direction will produce a corresponding variation in the angle of the truck to the foot-plate, the normal position being at right angles. The usual elastic cushion or spring, a, is placed between the truck proper and the frame 0, to prevent the truck from turning too easily. The wheels B B of each truck are preferably journaled on either end, respectively,of a shaft, b,which ex tends through a bearing, 0, on the truck. The shaft b is preferably provided at one end with ahead, I), and is inserted through one of the rollers, then through the bearing 0, after which the other roller is secured thereon. In order that the rollers and shaft may be readily detached, I provide at one end of the shaft 1) an annular groove, 2)", with which a spring-catch, d, is adapted to engage. This spring-catch d is provided with a circular opening, (1, having a notch or recess, d therein. The main portion (1 of the opening is larger in diameter than theshaft b. Thenotch or recess 1?, however, is smaller than the said shaft, but is suliiciently large to pass over the neck of said shaft in the groove Z1. The spring-catch bis adapted to extend at each end through a case, 0, on the rollcr,which covers the end of the shaft 1). The catch (Z is reduced at each end where it passes through the said case, and is adapted'to slide through the said case, which'fornis bearings therefor. Around the lower part of the catch (Z is a spring, (1, which rests at one end against the case, and at the other against a shoulder on the said catch. Now it will be seen that when the catch (Z is pressed down until the larger portion 11 of the opening comes opposite the bearing through the roller the shaft 1) may be passed through said catch, after which, upon releasing the said catch, the spring thereon forces it into the groove If, as shown in Figs. 12 to 14, thus holding the said shaft against longitudinal movement through the roller. I have shown a spring-catch at one end of the shaft only, the said shaft being removable from the bearing 0. It is obvious that the shaft may be made stationary and a spring-catch employed for each roller, if desired. The case 6, which incloses the spring-catch d, I prefer- IOO ably make of metal, with a backwardly-extending sleeve, e, as shown in Fig. 13, to form a bushing for the roller. -This bushing and case are held in place'bya cup-shaped nut, e, the opening or mouth of which isadapted to fit snugly over the end of the bearing 0. In this way the bearings of the rollers are completely incased, so that dust and dirt are prevented from entering therein, and the grease or oil from coming out. In Fig. 12 the bushing or sleeve is dispensed with, the case 6 being secured directly to the face of the roller by screws or otherwise.
Immediately above the bearing 0 is another bearing, 0, at right angles thereto, through which passes a pin, f, which forms the connection between the truck and the frame 0.
-Each truck is provided, immediately above the bearing a, with a table, 9, on one side of which is a flange or projection, 9. Above the table 9 is a plate, on which the elastic cushion a rests. Extending through the table 9 from the bottom are adjusting-screws g g, which bear against the plate 9 and serve to more or less compress the rubber a, and thus adjust the tension of each truck, as desired.
Above the elastic cushion a in the frame 0 is a thin metallic plate, against which bears the lower end of the cam-lever h. This camlever is pivoted at h to the frame 0, and is connected at its upper end by a stud, If, passing through a slotted opening, h to a movable head, h".
Journaled in' suitable bearings in the respective frames 0 O, and held against longitudinal movement therein, is a shaft, 1, provided at the center with a suitable hand-wheel, Z, secured rigidly thereon. This shaft is screwthreaded at either end with right and left threads, respectively, and engages with the respective heads h",which are each bored and tapped out to receive the respective screws. It will be seen now that as the hand-wheel Z is turned in either direction the movable heads h will be drawn toward or moved away from each other. This movement of the said heads h turns the cam-levers h down against or moves them away from the plate thus compressing or releasing the elastic cushions a. Means are thus furnished for readily and uniformly adjusting the tension of the elastic cushions over each truck of the skate, while by the use of the screws the tension of the cushion of each truck may be separately adjusted. The cushion a rests at one edge direetly against the side of the frame 0, while at the other edge it bears against the flange g on the table 9. The bearing 0 is made somewhat shorter than the distance between the sides of the frame 0 to which it is connected, so that a small amount of longitudinal movement of the bearing on the connecting-pin f is permitted. The pin f standing as it does at an angle to the foot-plate A, the weight which comes upon the said foot-plate is supported partly on the said pin and partly on the elastic cushion a, so that an undue pressure on the foot-plate from a sudden shock or jar causes the frame to move in the direction of the arrow, and as indicated by dotted lines in Fig. 7, thus compressing the cushion a and releasing the strain on the pinf.
It is obvious that the constructions shown and described admit of various modifications. In Fig. 6 I have shown two cam-levers, h, at the top of the cushion a and attached to the head h, the said cam-levers being connected together by alink, 71, In Fig. 15 I have shown a single adjusting-screw, g placed centrally in the table 9, for adjusting the tension of the separatecushions. InthisconstruetionIpreferably employ trunnions, f, which take the place of the pinfto form the hinged connec- Having thus described my invention, I
