Cables, or chains, 17 and 17 are attached to the opposite walls at the upper end of the chute with hooks 18 at their ends applicable to the hatch coaming to support and retain the chute against lateral movement that might be caused by the grain being delivered with force into the same in a lateral direction. It is preferred to use chains in lieu of cables for the reason that they permit the hooks to be applied to different links thereof to adjust their length in accordance with the distance between decks of the ship or distance from the chute to `points at which it is desired to attach the hooks.

The operation of my invention may be described as follows:

Ordinarily the grain delivered into a ships hold from a spout such as 8 is deposited in the bottom of the hold under the hatchway,

. and to fill the outer upper portion of the hold laborers with shovels are required to descend into the hold and shovel the grain into the upper corners of the hold.

Vith my invention the grain may be intercepted by the chute and deflected laterally and projected therefrom with suiiicient force so that it will be deposited into the utmost recesses of the hold through the medium of the force of the falling grain acting upon the curved plane surfaces of my improved chute.

lVith the spout positioned somewhat as indicated in Fig. 1 the chute is mounted therebelow with suihcient space between the lower extremity of the spout and the upper end of the chute so that the spout end will at all times be clear.

The chute is mounted by the cables 17-17 and 15 in adjusted positions so that the upper end of the chute will extend upwardly .through the hatch and the lower end will protrude into the hold in lateral directions and so that the upper extremity of the bottom 11 is nearly vertical andi therebelow where the falling grain will strike as it issues from the spoilt will impinge at a relatively sharp angle and thence to be deflected upon the curved portion of the bottom laterally toward the outward extremity of the ships hold.

The reaction of the grain upon the curved bottom will be sufficient to cause the grain to be projected for a considerable distance and to reach the outer walls of the hold and to issue in a stream of considerable upward trajectory so that the uppermost corners of the ships hold may be filled while the grain will slope inwardly toward the central axis of the ship which may from the spout.

The chute may be deflected up or down by means of the cable 15 to direct the stream of grain issuing therefrom at any angle desired and also may be swung fore or aft at an angle by shifting the hook 16 about the hatch coaming to direct the stream of grain forwardly or rearwardly of the hatch as desired.

It is desirable to provide the chute with a relatively broad7 flat bottom in order that the grain descending` from the spout will spread out and thus obtain through its falling force in reaction upon the chute bottom considerably more velocity in its projection from the chute than if confined within a curved bottom.

The cable supports 17-17 maintain the upper end of the chute in relatively fixed position under the spout, whereas the lower end may be cont-rolled and manipulated to direct the stream of grain in any direction desirable.

ln certain instances where stanchions or other obstructions may intervene the stream of grain issuing from the chute maybe further deflected to fill in the corners or upon the opposite sides of such stanchions by the workmen in the hold placing a deiiector, not shown, made of wooden plank and manipulated by hand in the stream of grain and further causing it to shoot off in one direction or another as the requirements demand.

The invention is very simple and easy to control and operate. Usually a chute is mounted in each hold of the vessel and the spout is moved to project the grain thereinto alternately, so that the vessel is loaded evenly and to provide opportunity for the stevedore to adjust the chutes not in operation to place the grain where needed.

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

1. The combination with a ship, hold and a hatchway opening into with a coaming about the hatchway, delivery chute comprising side walls be filled last by direct deposit having a the hold of a grain provided with shoulders adjacent the lower end of the chute adapted to abut the hatchway; the lower end of the chute extending horizontally into the hold and its upper portion being curved upwardly therefrom, and suspending means attached to the chute and having hooks thereon for attachment to the said .coaming 2. In grain loading devices7 the combination of a grain-chute having a flat bottom and side walls at right angles thereto throughout its length, said chute having an open top and having the opposite ends of its bottom disposed at approximately ninety degrees divergence, means to adjustably secure said chute in the hatchway of a vessel with the upper end of its bottom disposed at a relatively slight angle from the perpendicular, and a grain-spout arranged over said chute i to deposit falling grain vertically thereon.

3. The combination With a structure having a material receiving compartment, means for uniformly delivering material into the compartment comprising a longitudinally curved chute having a delivery portion arranged to extend laterally Within the compartment and an inclined intake portion eX tending upwardly from said delivery portion, and means disposed substantially at the juncture of said portions for engagement i5 with the sides of the compartment so las to limit the inward movement ofthe chute.

. 4. A chute of the class described, comprising a longitudinally curved bottom and substantially vertically disposed sides, said sides provided With abutting means for limiting the movement of the chute intoa ships hold.
