ASH-Hoist EPECIFICATIQN forming part of Letters Igatent No. 289,159,`dated November 27, 1883.

I Application filed August ld, 1853 i l (No medal.)

To all whom, it nur/y concern.

Be it known that I, JOHN D. SPREoKnLs, of the city and county of San Francisco, and State of California, have invented au Improvement in Ash-Hoists; and I hereby declare the following to be a full, clear, and exact description thereof.

Hy invention relates to van apparatus which is especially useful for hoisting ashes from the fire-rooms of vessels and discharging them overboard; and it consists, mainly, of a receiver for the material at the bottom, aline of carrying-buckets with a suitable driving inechanism, by which the buckets are caused to pass through the receiver to load themselves and pass thence to the deck above, a receivingchute or disch arge-pipe leading out through the side of the vessel, and a means for keeping it clear and preventing choking, together with certain details of construct-ion, all of which will be more fully explained by reference to the accompanying drawings, in which- Figure l is a perspective view of my apparatus. Fig. 2 is a vertical section of the same. A. is a receiver, which is fixed in the door or hearth of the lire-room, or in any convenient place, so that when the ashes are to be discharged [which is usually about once in six hours) they may be easily raked into the receiver. Its sides may be vertical and sufficiently separat-ed to allow the buckets to pass between them. The bottom is rounded or curved, and a roller or pulley, B, is journaled to turn between the sides of the receiver, so that the buckets C (which are preferably secured to a leather belt, D, to lessen the noise of working) may-be carried down by the belt and dip into the receiver, so that as they rise upon the other side they will load themselves. The belt D extends around a roller or drum, E, upon the upper deck, at any suitable or convenient point, and both parts of itare inclosed by a casing, F. At the top the upper drum-shaft extends out, and has a gear-wheel, G, keyed to it, which is engaged by a pinion, H, upon the engine-shaft I. The shafts, gears, and the engine J, by which they are driven, are all mounted upon a frame, Ii, properly secured to thevessel. A discharge pipe or chute,

5o Il, extends from the upper deck downward,

and is curved outward, so as to discharge through the side of the vessel, and its upper end has a hood, M, extending upward and curving partially over the upper bucket-roller, so as to insure the discharge of the contents of the buckets into the chute without scattering. The chute extends down through the second deck in a nearly-vertical position, and below this deck it curves outward, so as to assume a more nearly horizontal position and pass out through the side of t-he vessel, thus obstructing the interior space to the least extent. As the material is apt to clog when discharged through this chute, an opening or passage, N, is made into it, entering, preferably, about in line with the direction of the lower portion, and a water-pipe connects with it with a valve, O, through which a body of water from the pump may'be discharged through the pipe and forcibly clear it or prevent any lodgment of mate` rial within it. l

P isv a gate or valve fitted into the dischargechute near its outer end, and serving to close it when not in use, and thus prevent any ingress of water from the motion of the vessel or the action of the sea. This valve swings in a chamber of somewhat larger diameter than the rest of the pipe, so that when open it is out of the way and leaves a clear passage. Its shaft has a 1ever-ar1n with a connecting-rod and hand-lever, by which it may be opened and closed, and a curved link or rack with setscrew or pawl to hold it open or closed at will. At a point above the deck Q where the donkey-engines are usually placed I make a door, It, in the side of the chute Il, and a plate, S, is fitted into the chute, so that when in place it extends upward and backward from the lower edge of the door-opening at an incline.

`This device is used whenever it is desired to hoist coal from the refroom bunkers for the use of the donkeyengines, and the coal, being taken from the receiver A, is carried up by the buckets and discharged into the chute, flowing down to the incline-plate S, which directs it outward through the door-opening upon the deck. When ashes are to be hoisted, this plate is removed and the door closed. The ashes are rst wet down, so as to cool them, and also prevent their injuring the elevator-belt, after which they are raked into the receiver, and the buckets, being in motion, will IOO scoop them 'up and carry them to the top,where they discharge them into the chute, through which they escape overboard, as before described.

. Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isv l. A device for hoisting and discharging ashes, adapted to be carried by a vessel, and consisting of a receiver placed near the furnace, a chain of buckets, and a discharge-chute, connected substantially as described.

2. The discharge pipe or chute L, in combination with the water-pipe or flushing-passage opening into it, substantially as herein described.

In an apparatus for discharging ashes or material from a vessel, the discharge pipe or JOHN D. SPRECKELS. Witnesses:
