PLATFORM FOR TRUCKS.

SPECIFICATION forming part of Letters Patent No. 351,145, dated October 19, 1886.

Application filed July 22, 1886. Serial No. 209,732.

To all whom it may concern:

Be it known that I, THOMAS WVRIGI-I'r, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Platforms for Trucks, of which the following is a full, clear, and exact description.

My invention relates to an improved construction of platform of four-wheeled vehicles; and the invention consists, principally, of the employment of double inverted arch-bars for holding and supporting the forward ends of the cross-pieces of the platform, whereby the platform is made lighter and cheaper than ordinary platforms, and at the same time stronger and less liable to sag.

The invention also consists of the construction, arrangement, and combination of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my new and improved truck-platform, showing the axle-tree and the fifth-wheel. Fig. 2 is a front elevation of the same, and 3 is a side view of the same.

A Arepresent the springs secured upon the axletree B in the usual manner, and the rear ends of the springs are bent upward and se cured to the rear bar, 0, in the usual manner. The forward ends of the springs are connected to the front metal bar or plate, D. Upon this plate D is placed the arch-bar E, on which rest the forward ends of the several cross-bars F F. The rear ends of these cross-bars are framed into the rear bar, 0, in the usual manner. Upon the forward ends of the cross-bars F is placed the upper arch-bar, G. Both archbars are bolted or riveted at their ends to the front plate, D, and the springs A, and down through the arch bars,the cross-piece F, and the front plate, D, are passed the heavy bolts H, 011 which are placed, between the lower arch-bar and the front plate, D, the supporting-blocks I, which prevent the arch-bars and the front (No model.)

plate from springing when the nuts on the bolts are turned home. The short center piece, J, is framed into the crossbars F in the usual manner, and in it is formed the king-bolt hole 6, and upon the bars F is secured the fifth wheel K, in the usual manner.

By constructing the forward part of the platform, as described, with the two arch-bars united by bolts to each other, and to the crossbars F and front plate, D, and supported by the blocks 1, the platform is very cheaply made, and is comparatively light, and is very stiff and strong, so that the platform will not sag and cause binding of the truck at the fifthwheel in turning, which is a great difficulty now experienced with trucks having a wooden front piece for supporting the forward ends of the bars F.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a truck-platform, the combination, with the bars F, of the bent arch-bar E, conneeting the side springs of the platform and supporting the ends of the bars F, substantially as described.

2. In a truck-platform, the combination, with the bars F, of the two arch-bars E G, between which the bars F are held, substantially as described.

3. The combination, with the arch-bar E, bolts H, bars F, and supporting-plate D, of the blocks I, placed upon the bolts H be tween the arch-bar and the plate D, substantially as described.

4. In a truck-platform, the two arch -bars E G, resting at their ends, upon the plate D and springs A, in combination with the crossbars F, held between the arclrbars, the blocks I, and the bolts H, the blocks being placed upon the bolts between the arch-bar E and plate D, substantially as described.
