ROLLER-SKATE.
SPECIFICATION forming part of Letters Patent No. 319,787, dated `Tune 9, 18851 Application led November 29, 1884. (Model.)
vTo all whom it may concer-i1,.-
r; new and useful Improvements in Roller- Skates, of which the following is a specication.
My invention relates to an improvement in iollerskates, whereby a simple, strong, durable construction is obtained.
One of the features of my invention consists in providing a pivotal axle for the hangerv bracket, which may be used as a temper-screw to regulate the tension of the`spring-cushion.
Another feature of my invention is the use of an automatic spring to lock the axlein position.
Another feature of my invention relates to the use of stops to prevent the foot-board from being inclined far enough to either end to strike the rollers, which endangers the equilibrium of the operator, all of which will be set forth in the description of the accompanying drawings, making a part of this specification.
Figure l is a central vertical longitudinal section of my improvement. Fig. 2 is a plan view of the spring-chair. Fig. 3is a front elevation of Fig. l', with roller removed. Fig. 4 is a side elevation of my improvement. Fig. 5 is a front elevation of the roller axle and frame. Fig. 6 is a side elevation of a modilied form of pivoting the spring-seat frame.
A represents one of the ordinary skate-rollers; B, the axle on which the rollers journal.
O represents the roller-frame.
Drepresents a journal-bearing bored through the frame G, which serves as a journal for the axis of the hanger-frame.
E represents the top face, which is a plane.
surface, and serves as a seat for the rubber spring-cushion.
F represents the hanger or bracket frame. It is provided with downwardly-projecting pendants or arms G H.
I represents flanges upon each side of arms G H, for securing the frame to the bottom of any desired form of foot-board.
Krepresents a spring chair-frame. It is provided with a slot or opening, L, through which projects arm H.
M represents a gain at the opposite end, en gaging pendant G.
c c represent hooks or turned points, engaging over the ends of flanges I I, Which are slightly rounded at points opposite the hooks 'c c, so as to allow them to rock or turn freely thereon.
d represents ledges or sides for supporting the rubber spring-cushion N.
O represents a lug projecting downward from chair K and hanging opposite the point of axles b. The top of the frameKserves as the upper seat of spring N.
The spring is compressed or adjusted by the following means: The front end of axle b is screw-threaded and taps through pendant H, and as it is turned inward strikes against lugO of frame K, pushing it out from pendant H, the hooks c c turning on the frame F and bringing seat E down upon spring N, which is compressed between the seats E e. A' reverse movement of the screw-axle b takes off compression from spring N.
In order to guard against liability of the turning of axle b, I provide lock devices. The barrel of axle b is made smaller than the squared head P, which serves as a turning-v head on which a key or wrench is fitted.
R represents a spring attached at oneend to arm G. It is provided with a slot, r, whose Width is such as to fit the square side of head P, but is less Ithan the diagonal dimension of the head; Spring R hangs normally with the slot engaging the square head l?, which is thus prevented from accidental turning.
When it is desired to turn axle b, a key is inserted on head l?, and spring R is pushed over the same onto the barrel, which is smaller than head l?, and then the screw-axle b may be readily turned. Vhen the key is removed, spring R retracts and occupies the position shown in Fig. 1, locking axle b in position.
In order to prevent the bracket F and footboard of the skate from being tilted too far, so as to cause the foot-board to strike the rollers A, I have provided stops a a on the rollerframe C, against which one of the sides d of the chair K will strike, and prevent further IOC the foot-board should strike rollers A, their revolving would be stopped, and the operator would be in danger of being thrown by the sudden checking or turning of the direction of the skate movement, all of which I eifectually avoid by the use of these stops.
A modication Yof my Vinvention could be formed by employing a stationary axle, b, and inserting a temper-screw through the pendants G II above and in the same plane there.
of; but the form here shownI deem the best.
Instead of providing the frameK with hooks c, frame K may be made ofthe shape shown in Fig. 6, and the hanger-frame correspondingly changed in shape, 1 representing a circular seat on which the frame K journals, which is grooved of corresponding shape to t and bear thereon, and is an equivalent for the form o'f construction shown in the other gures of the drawings.
What I claim as my invention is- 1. In a roller-skate frame, the oscillating spring-chair K, provided with the pendent lug O, in combination with the temper-screw b, bearing against the lug O, to adjust the chair as described,
2. In combination with the truck-framel the bracket or hanger frame j ournaled on an axle, which serves as a temper-screw to adjust the chair K and regulate the spring-tension, substantially as specied.
3. In combination with bracket F, oscillating spring chair K, and temper screw b, bearing against the latter, of the lock-spri ng R, for holding the screw against the chair, substantially as described.
4. The truck-frame C, provided wit-h stops a a, in combination with the bracket F, and the oscillating chair-seat K, interposed between the bracket and frame and having sides d, against which the stops a a are adapted to strike, substantially as described.
In testimony whereof I have hereunto set my hand. l
