TRUCK.

SPECIFICATION forming part of Letters Patent No. 429,463, dated June 3, 1890.

Application filed February 6, 1890. Serial No. 339,407. (No model.)

To all whom it may concern.-

Be it known that I, HENRY MARTIN, a citizen of the United States, and a resident of Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Trucks; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which-- Figure 1 is a perspective view of my improved truck, showing the upper frame or deck open. Fig. 2 is a side elevationof the same, but showing said upper frame or deck in its down or closed position; and Fig. 3 is a detail view of one of the hinged or jointed corner supports or bearings.

Like letters of reference denote corresponding parts in all the figures.

This invention relates to trucks or vehicles for carrying loads of bricks or pallets; and it consists in certain improvements upon the truck for which Letters Patent No. 314,594 were granted to me on the 31st day of March, 1885, as will be hereinafter more fully set forth, and particularly pointed out in the claims.

Reference being had to the accompanying drawings, the letter A designates the truckframe,which may be mounted on either one or two wheels, as desired. Upon the forward part of this frame is hinged at B a rectangular frame 0, forming the lower deck or palletframe in precisely the same manner as described in my patent, No. 314,594, the free end of said frame resting on both sides about midway of its length upon the side springs S; but instead of constructing the upper deck or pallet-frame in a single piece, as shown and described in my above-mentioned patent, I conor corner-bearings F are of such aheight that when the upper frame-sections D and E are closed or folded down upon the lower frame 0, as illustrated in Fig. 2, there will be sufficient room between the two frames for the pallets of brick which are placed upon the lower frame, so that the upper frame may be folded down over the pallets resting on the lower frame without coming in contact with the brick placed thereon. The inner ends of the upper frame-sections are supported in this down or folded position by means of elbows or angle-irons G, one arm of which is bolted to the under side of the sides of the respective frames, while the other arm forms a foot rest or support for the frame upon the sides of the lower frame 0. When the upper frame-sections are in the raised or elevated position illustrated in Fig. 1, they are pre vented from tilting back too far by their rearward extensions f back of the jointed supports F, which by abutting against the corners of the lower frame will form a stop to the backward motion of the hinged frame-sections. Then these sections are in their down positions, resting upon the legs G, they will be aligned with each other, so as to form a smooth top surface or upper deck, upon which to support the upper tier of brick pallets. The objects of constructing this upper deck in two parts or sections instead of in a single piece, as in my patent, No. 314,594, are several and of considerable practical importance. It permits of the raising of the upper frame to remove the pallets of brick placed upon the lower frame without its inner ends striking against the racks of the drying-room. Again, as the raised ends face inwardly toward each other and toward the middle of the truck,

there is no danger to the workmen who handle the truck and brick pallets from injury from blows by the heavy frame falling down from its raised position and striking them on the head or otherwise inflicting injury, as is apt to happen where a long frame is hinged to the truck at one end only. Moreover, by making the upper deck in two sections it requires less effort to raise it, and as the meeting ends of the frame come together exactly over the middle of the sprin -support and are there supported by the foot-rests, the middle of the frame,where the strain is greatest, is not liable to sag as where the frame with its load is supported at the ends only.

It is obvious that, if desired, the springs S may be dispensed with, orasingle spring may i United States 1. The combination of the truck-frame, the lower pallet-frame hinged at one end to the same, and the upper deck or frame constructed in two parts or sections hinged at their outer ends to the corners of the lower palletframe, and provided at their inner free ends with feet or supports adapted to rest upon the sides of the lower deck or pallet-frame, substantially as and for the purpose set forth.

2. The combination, in a vehicle or truck of the described type, with the lower palletframe, of the upper hinged and divided frame supported at its corners by jointed bearings and provided with feetcorresponding inheight to said bearings and adapted to sustain or support the middle part of said upper frame upon the sides of the lower frame, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two Witnesses.

HENRY MARTIN.
