IMPROVEMENT IN TRUCKS.

Specification forming part of Letters Patent No. 122,686, dated January 9, 1872.

SPECIFICATION.

We, ANTHONY VAN HAAGEN and JOHN H. COOPER, both of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented an Improvement in Trucks, of which the following is a specification:

My invention consists of a truck constructed in the peculiar manner too fully explained hereafter to need preliminary description, the truck being designed for the conveyance from place to place of blocks of soap, marble, stone, packages, &c., with the view of saving much of the labor demanded in moving such articles with ordinary trucks.

Figure 1 is a side View of our improved truck; Fig. 2, a plan view; and Fig. 3, a vertical section of the lower portion of the truck on the line 1 2, Fig. 1.

The frame of the truck consists of the op posite sides A and A, connected together by the front, 13, but disconnected at the rear, the whole being, in the present instance, cast in one piece. To each side of the frame, near the rear end of the same, is hung a pin, D, on which is loosely hung a wheel, E, the rear of the truck being supported by these wheels E, and the front of the truck on a smaller wheel, F, hung to the forked end of a vertical spindle, G, which turns in a projection, a, on the front end of the frame, the spindle being furnished with a suitable shaft, H, by which the truck is guided and drawn over the ground. Two rods, I I, are arranged to slide and turn in, and are guided by lugs b b on each side of the frame, the rods also passing through.

projections 61 d on a plate, J, above which plate each rod has a collar, 6, and handle f,- and the lower end of each rod is provided with a plate or arm, h, which, by turning the said V rod, can be moved to a position beneath the object to be lifted, as shown in Fig. 3, or can be moved on one side, so as to be clear of the said object. The vertical position of the plates J, and consequently of the rods I I and of the load, is controlled by bell-crank levers K, one lever being hung to a pin, 4., on each side of the frame, and each plate J bearing upon a roller at the end of the short arm of one of the levers, as shown in Fig. 1.

Our improved truck, although well adapted to the moving about from place to place of the truck is so backed that the opposite sides I of the frame will be on opposite sides of the block, the plates h having been previously moved outward by turning the rods I I, and the plate J, with the said rods and plates, having been lowered by raising the long arm of the lever K to the position shown by dotted lines.

The truck having been adjusted to the position shown in Fig. 2, in respect to the block X of soap, the plates or arms h are so turned as to take their places beneath the board M, and the opposite levers K K are then simultaneously depressed, thereby causing the short arms of the same to elevate the sliding plates J and with them the rods I I and the block of soap, to an altitude determined by a stop, :0, formed on each plate, with which stop the roller on the short arm of the lever comes in contact, as shown in Fig. 1. hen the levers are in this position their short arms are so inclined from the perpendicular, that, resting against the stop on the plates J, they serve to support the block of soap, the Weight of which cannot disturb the levers.

The block being now supported by the truck may be moved with the latter to the desired position on the floor, when, by elevating the long arms of the levers K, the block can be lowered until the board M is in contact with the floor, when the truck, after turning the arms h h outward, is at liberty to be used in moving another block. A horizontal bar, 02, supported by rods 10 and stayed by diagonal rods q, serves as a handle, by which attendants can aid theman at the shaft H in drawing the truck and its load over the floor.

It will be evident that the truck can be used for conveying blocks of marble or stone, cases of dry goods, 850., from place to place.

It will also be evident that by combining a 7 equivalents, through the medium of which the said arms h k can be raised or lowered.

3. The combination of the said sliding plate J and its stop a: with the bell-crank lever K.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
