SPRING-PLATFORM FOR ROAD-WAGONS.

SPECIFICATION forming part of Letters Patent No. 435,861, dated September 2, 1890.

Application filed May 29, 1890. Serial No. 353,683. (No model.)

To all whom it may concern.-

Be it known that I, CYRUS \V. SALADEE, a citizen of the United States, and a resident of Cleveland, State of Ohio, have invented certain new and useful Improvements in Spring-Platforms for RoadWVagons, of which the following is a specification embodying my said invention, and the same is specifically pointed out in the appended claims.

The invention has for its object the short turning of the vehicle and the improved construction and arrangement of the several parts constituting the front and rear platforms adapted to support the body at opposite ends, all as hereinafter more fully described, and as represented in the annexed.

drawings. The front and rear platforms shown and described are independent of each other, and either may be used to support one end of the body, while any other well-known means may be employed to support the opposite end.

In the drawings, Figure 1 is a side elevation of the body-sill representing the connection therewith of the inner ends of the front and rear spring-platforms, respectively. Fig. 2 is a detached plan view of the front platform. Fig. 3 is a plan view of the rear platform. Fig. 4 is a plan View of the upper plate of the fifth-wheel coupling seen in Figs. 1 and 2. Fig. 5 is a detached plan View of the crossbar connecting the springs and rearwardlyextended arm seen in Fig. 2. Fig. 6 is a detached plan view of the front end of the lefthand spring seen in Fig. 2. Fig. 7 is an enlarged end view of the rear axle in section, showing a box-loop connecting the end of the spring thereto. Fig. 8 is an enlarged end view of the axle in section, showing a boxloop connecting the spring thereto suspended from a pivotal bearing instead of upon a slid ing bearing, as seen in Fig. '7.

g I proceed to the construction of the front spring-platform seen in Figs. 1 and 2 substantially as follows: The diagonally-arranged springs A A have their terminal ends connected to the axle and their inner ends united by a cross-bar O and rearwardly supported upon bearings C and 0', preferably upon a longitudinal bar 0, having its rear end supported upon a friction or roller bearing D,

and its forward end connected to the crossbar 0. Said friction or roller bearing D rides upon a segmental plate or bar III, which latter is suspended by its opposite ends from the bottom of the body at such requisite point as will admit of placing and operating said bearing D between the bottom of the body and said segment H. The outer ends of said plate H are connected to the bottom of the side sills of the body, preferably by the intermediate spool J and bolt J passing through the sill of the body, the spool, and the end of said plate, as clearly seen in Fig. 1. For the purpose of supporting the center of said segment-plate 11 against the downward pressure of said bearing D thereupon the bracket F is employed, having its rear end bolted to the bottom frame of the body and its front end bent down and secured to the under side of said plate H, as clearly seen in Fig. 1. If preferred, the spools J may be omitted and the ends of the plate 11 be bent up and attached directly to the side sills of the body.

The longitudinal bar 0 is provided with ears 0, preferably integral therewith, adapted to support the rear ends of the springs A A thereon by a bolt 0'. Both ends of this bar 0 are, in this instance, bent up, the rear end to take the roller D and the front end to unite with the cross-bar O. The D-plate E of the fifth-wheel is secured to the bottom of the body and its under face rests on the friction-plate E. Interposed between the latter and the cross-bar O is the bearing K, by which latter the hang of the body in front is regulated according to the height given said bearing. The terminal ends of the springs may be secured to the under side of the axle, as seen in Fig. 2. For the purpose of setting the clips S S in a right-angle position to the axle and at the same time omit piercing a hole through themain plate of the spring, as at S', Fig. 2, a projecting car A is formed on the outer edge of the plate, through which the inner clip-hole is pierced. (See Fig. 6).

In the rear springplatform, Fig. 3, substantially the same combination of parts is employed, as shown and described in the front platform, omitting thefifth-wheel and roller.

A cross-bar 0, having a forwardly-extended arm P centrally connected therewith, serves to support the inner ends of the springsB B, as clearly shown in Fig. 3. Theouter ends of the bar 0 connect to the side sills of thebody by bolts 1 and 2, and the forward end of the bar P is bent up and bolted to the center sillpiece of the body, as shown in Figs. 1 and 3. A support T (see Fig. 1) is interposed between the bar 0 and the body, whereby to regulate the hang of the latter in relation to the ground according to the depth given said support.-

Springs that are obliquely extended from the bottom of the body to'the axle and having the usual downward curvature tend to spread apart at their terminal ends when depressed underthe weight imposed in the direction of the arrow-points G G, Fig. 3. To provide for this tendency and relieve the springs from the lateral strain it. imposes upon their main plate, I shall employ either a sliding box-loop B, substantially as seen in Fig. 7, or a swinging box-loop B, as seen in Fig. 8. In either case said loop is made a detachable head connecting one or both ends of the springs to the axle in such manner that either or both ends of said springs may spread apart at their attachment to said axle to any extent the depression of the spring may require such movement.

In Figs. 3 and 7 the box-loop B is made to loosely fit and inclose three sides of the axle L, its lower ends terminating in bearings X. X, which are secured to the face of the main plate A of the spring B on the inside of the axle by the clip R and in front by the bolt B. By this method of attaching said loopto the spring-plate I avoid piercing the usual clip-hole at the junction with the axle or loop X. As before stated, this box-loop B is fitted to the axle loosely-that is, in such a manner that it and the'spring-plateAshall firmly clasp and inclose the axle, yet admit of its sliding thereon, as and for the purpose already described.

In Fig. 8 a bolt R passes through the top ends of the loop 13 and the head R secured to the top face of the axle, while its base is clipped and bolted to the end of the springplate A, as at R and R. In this case the ends of the springs are permitted to spread apart by swinging on the bolt R in place of sliding upon the axle, as in Fig. 7.

As before stated, one or both ends of these box-loops may be operated as described, or, if preferred in any case, the one may be stationary and the other operative on the axle in either or both of the platforms, Figs. 2 and In the latter case I prefer to secure the stationary end of the spring as per the attachment seen at A, Fig. 3, and in the front platform, Fig. 2, as at A, and the other end of the spring by either of the box-loops B seen in Figs. 7 and 8.

Without limiting my claims to the precise arrangement of the several parts shown and described, I claim-- 1. The combination, in a front spring-platform for road-wagons, of obliquely-extended springs A A, having their front ends attached to the axle, their rear portions .united by a cross-bar 0, connected to the bottom frame of the body by a king-bolt or other equivalent fifth-wheel device, a segment-plate H, rigidly secured to and suspended from the bottom of said body, and a friction or roller bearing D, secured to the terminal rear ends of said springs and adapted to ride upon the top surface of said segment-plate when turning the vehicle to either hand, substantially as set forth.

2. In a front spring platform, the side springs A A, diagonally extended from the bottom of the body to the axle, a cross-bar (3,-

uniting the springs near their innerends and connected to the bottom of the body by the king-bolt L, the arm 0, rearwardly ex tended from said cross-bar and adapted. to support the rear ends of the springs, and a friction or roller bearing D, riding upon the top face of the segment-plate H, the opposite ends of the latter being rigidly secured to and suspended from thebottom of the body, substantially as shown and described.

3. The combination, in a rear spring-platform for road-wagons, of side springs obliquely extended from the bottom of the body and secured to the axle at widely-separated points, the inner ends of said springs being maintained by the opposite ends of the cross-bar O, and a longitudinally-arranged central arm P, connected to said cross-bar and forwardly extended to form the upturned bracket 0, whereby to secure the latter to the bottom frame of the body, substantially as shown.

and described.

4. The combination, in a rear spring-platform of the character described, of side springs extending from the bottom of the body and secured to the axle at widely-separated points,

the inner ends of said springs being supported by the cross-bar O and forwardly-extended arm P, the opposite ends of said cross-bar being secured to the bottom frame or sills of said body and having a support T interposed between the bar and said bottom frame of the body, whereby to regulate the hang of the latter in relation to the ground, substantially J. A. GRAIN, J. W. I-IENNEY.
