APPARATUS FOR UNLOADING VESSELS.

SPECIFICATION forming part of Letters Patent No. 258,237, plated May 23, 18 82.

' Application filed J anuary 30, 1882. (No model.)

unloading grainor other similar materialfrom vessels and. it consists of a conveyor and its operating mechanism arranged Within the vessel lengthwise of the same, in combination with one or more elevators arranged upon a shaft,

so as to be capable of a swinging movement with the shaft, and also an easy horizontal movement back and forth along the same, the whole being connected with the necessary operating mechanism, as will be more clearly hereinafter shown by reference to the drawings, in which-- Figure 1 is a side elevation of the apparatus and a portion of the interior of the vessel to which it is connected. Fig. 2 is an end view of the apparatus. Fig. 3 represents a plan or top view of the same, and Fig. 4 is an enlarged cross section through one of the shafts upon which the elevators are hung.

In the drawings, A in Fig. 1 represents a. portion of the interior of a vessel, 0. beinga portion of the deck, to which the hangers B for supporting the shafts b b are secured by bolts or in any well-known way. The shafts b b are provided with one or more grooves or keyways, 0, (shown in Fig. 4,) and the holes in the upper elevator-pulleys, c, are provided with keys or feathers to tit said grooves, so that the elevators may be moved easily along the shaft without turning thereon, and so that the pulleys cwill have to turn when the shafts b or b are turned. The elevator-belts are tightened by means of set-screws D (see Fig. 2) and a sliding box, at. There may be two or more elevators, E, arranged on a shaft, and they may be placed all on one side of thecon- Veyer or arranged on shafts on both sides, as

shown in Figs. 2 and 3.

move with it.

.The conveyor consists of an endless chain, c, arranged on the usual chain-gear wheels, F, one at each end, the chain(or belt or cable) being provided with a series of plates, f which The endless chain c rests on a bed, G, which bed is provided with vertical sides 9, so as to form a kind of trough or vessel to hold the grain, along which theplates f move in the direction of the arrows (see Fig. 1) when the device is in operation. The conveyer is operated (also the elevators) by means of a driviug-pulley on one or the other of the shafts b or N, which turns (through the gear-wheels H H) the gear-wheel'h and it will be seen that the turning of the shaft 1) by means of a pulley, as aforesaid, arranged in any well-known way, will operate the shaft 1) and all the elevators thereon, and that the proper movements will be transmitted to the other shaft, W, by means of the shaft I and the gear-wheels i i i on its opposite end.

In place of the conveyer shown, an ordinary screw-conveyer may be used; but it would not answer the purpose so well. A

In operating with my invention when the vessel is full of grain the elevator-legs are all turned so as to lie on top of the grain, from which position they swing down as they take away the grain and throw it into the conveyer, which carries it forward and drops it, so that it can be taken up by an ordinary elevator into an elevator-building. When the elevators E swing down into a vertical position, after taking away all the grain in their path, they are turned up and moved horizontally along the shafts b 1) into the proper position to take out another portion of grain, which operation is continued until the greater portion of the grain is taken away from the vessel.

I claim as my invention-- 1. An elevator, E, arranged upon a grooved shaft, 1), so as to be capable of both a horizontal movement back and forth along the shaft and a swinging movement as described, in combination with a conveyer arranged to move at right angles, or nearly so,to the movement of the elevator, and the operating mechanism of the several parts, substantially as specified.

2. The shafts l" b each provided with grooves 0, and an elevator, E, and their operating mech d anism, substantially as specified, in combination with a conveyor provided with a series of plates,f, arranged within a trough, G g, and

their operating mechanism, substantially as described.
