SPRING-BOARD WAGON.
SPECIFICATION forming part of Letters Patent No. 295,635, dated March 25, 1884.
Application filed November 1, 1883. (No model.)
To all whom it may concern:
Be it known that I, JOHN C. F. HARRIS, of
Littleton, in the county of Grafton and State of New Hampshire, have invented a new and Improved Spring-Board \Vagon, of which the following is a full, clear, and exact description.
My invention relates to improvements in spring-board wagons; and it consists of a footboard mounted on the spring-board by springs more yielding and having longer range of movement than the springboard itself, to protect the feet of the rider from the benumbing jar of the spring-board; and it also consists of a novel arrangement of springs with the seat,
to render its motion easier than the motions it is subject to when positively connected to the spring-board, all as hereinafter fully described.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation of my improved springboard-wagon body with a part of the seat in section. Fig. 2 is a plan view with a part of the seat broken out; and Fig. 3 is a sectional elevation on line mm, Fig. 1, looking forward, and with the seat raised.
The spring-board A is connected at the middle, between the ends and under the seat E, by the cleats a, bearer a, and clip-bolt aflwith the semi-elliptic spring 13 extending along under the middle of the spring-board nearly from one axle to the other, and suspended from the spring-board near the axles by the shackles C, so that the spring re-enforces the board along the middle with much greater supportingpower than the board possesses, which power is so graduated by the nature of the spring that greater resisting-power is developed in proportion as the weight on the springboard is increased, thus preventing the spring-board from being overpressed and sagging, as such spring-boards do after short service.
shackles are to be constructed with broad and substantial wearing parts in the joints, and with broad attaching-p1ates c for substantial connection with the spring-board.
To prevent the benumbing effect of the springboard A on the feet of the rider when exposed to the short, sharp, and rapid shocks The.
of such boards, I propose to mount a footboard, G, on the springboard by the elastic fiat springs g, as shown, said springs being arranged to have sufficient flexibility and range to wholly overcome the strong and rapidshocks of the spring-board; and'to prevent the recurrence of the shocks of the spring-board by the foot-rest being over-pressed and forced down on the spring-board, I propose to apply one or more'rubber cushions, g, to the under side of the foot-rest.
For relieving the seat from the jars of the springboard as much as possible, I hinge the seat to its support H at the front h, and arrange the fiat steel Springs (1 under the middle of the seat, or thereabout, with rubber cushions b at the back, to soften the shocks when the seat is pressed down on the seat-supports D road. For the support of these springs d, I
make a rack consisting of side bars, (2, center cross-bar, (72", and spring -holding crossbars (1 and d, in which the springs are arranged independently and so as to be secured between the side bars by the cross-bars, and I mount this rack on the side of the back-support D of the seat by a strong bolt, d", and with stud-pins d, projecting from the surface of support D under the rack, so as to prevent it from vibrating on the bolt in case the seat is pressed down with more weight on one end than on the other. -I may fasten the springs d in the raclcfraine in any suitable convenient manner.
At the sides of the seat-supports D, and in the proper location for protection of the same from the wear of the front wheels when turning short around, I propose to apply wearirons F, having an upper rib, f, and a lower one, f, adapted to fend off the wheels alike rubber cushions I) above the seat-supports,
substantially as described.
3. The combination, with the hinged seat E, of springs (I, supported in the frame, consisting of side bars, d, and cross-bars, as described,
and attached to seat-support D by bolt cl, substantially as specified.
