ASH-EJECTOR FOR SHIPS.

SPECIFICATION forming part of Letters Patent No. 482,759, dated September 20, 1892.

Serial No. 426,912. (No model.)

To all whom it may concern:

Be it known that I, HORACE SEE, of the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Apparatus for Ejecting Ashes and other Refuse from the Holds of Ships, which invention is fully set forth and illustrated in the following specification and accompanying drawing.

The object of this invention is to render more certain, useful, and efficient certain forms of apparatus heretofore employed as ashes-ejectors.

The invention will first be described in detail, and then particularly set forth in the claims.

The accompanying drawing illustrates the improvements embodying my invention.

In said drawing the several parts are indi cated by reference-letters, as below described.

The letter A indicates a receptacle, preferably shaped like an inverted hollow cone, forming a hopper, into which the ashes to be removed are thrown by means of shovels or otherwise; a, a lid or cover to the hopper, secured thereon by hinges and screws or bolts so as to fit on the hopper with a watertight joint of any approved construction. A draincock B is fitted to the upward discharge-pipe C, so as to drain any water remaining in the hopper or in said pipe after the apparatus has ceased to operate. The jet-cock D is a conr inon straight-way cook (or maybe any simple valve) for opening and closing communication between the jet-pipe E and the dischargepipe 0 through the jet-nozzle F, which makes a water-tight joint with the discharge-pipe O.

Inserted between the main line of the ejector-pipe E and the cock D is a side branch or passover pipe and valve G H, which pipe connects the pipeE and the lower portion of the hopper A. By means of this by-pass the ejector-pipe and ashes-discharge pipe may be used as a line of pipe for the discharge of bilgewater by the ejector-pump or by any suitable bilge-pump when the apparatus is not in use as an ashes-ejector.

The operation of the apparatus as an ashesejector is as follows: The lid or cover a of the hopper A being closed, the drain-cock B is opened and any water that may be in the rislug or discharge pipe 0 is drawn oif. This cock being again closed and the cock D also closed, the pump (not shown) is started and an initial head or pressure accumulated sufficient to force the ashes up and overboard through the pipe G. Then said pressure is sufficient, the cock D is opened, when the cover a may be raised and the ashes thrown into the hopper A in suitable quantities successively. As the ashes fall to the bottom of the hopper and into the base of the dischargepipe they encounter the current or jet from the jet-nozzle F and are by the force of the jet carried with the water up the pipe G, and thence by it discharged through the side of the ship overboard. When the ashes are all discharged, the cover is again closed and secured before the pump is stopped. This will prevent any backfiow of water out of the hopper due to the head of water which may remain in the pipe 0 when the pump is stopped.

The apparatus or plant when not desired for use as an ashes-ejector is converted into a bilge-discharging apparatus by simplyopening the valve H and closing the valve D and hopper-cover a and starting the pump connected to the pipe E. This plant or apparatus therefore dispenses with the necessity of employing a separate pump and line of discharge-pipes for pumping out the bilge, one single plant performing either function alternately of bilge-pump and ashes-ejector, as oocasion may require.

I am aware that cocks or a three-way cock have been suggested for ashes-ejecting apparatus to first freely discharge the ejecting water and then suddenly shut it 01f and divert it upon the mass of ashes to discharge them, and such means I do not claim. I have discovered that certainty and efficiency in discharging the ashes are secured only by locating an ejector-cock in close proximity to its ejector-nozzle and keeping said cock closed until after the ej ector-pump has created a high ing said cock and letting the full head of water impinge upon the ashes at the base of the dischargepipe in front of the ejector-nozzle.

The attachment J on the pipe 0 is an airvalve or vacuum-valve, which automatically opens should a vacuum form in said pipe, the

formation of which W0 'uld impair the efficiency of the discharge of solid and liquid matter combined.

Having thus fully described my invention, 5 I claim 1. In an ashes-ejector, the combination of an ash-receptacle, a jet-pipe provided with a valve or cook located in close proximity to the jet end of the pipe for opening and closing 10 the jet-orifice, and a discharge-pipe connected to said ash-receptacle and jet-pipe to discharge said receptacle through its bottom, substantially as and for the purposes set forth.

2. In an ashes-ejector, the combination of an ash-receptacle provided with a removable cover or seal, a jet-pipe, a discharge-pipe, and a bilge-discharge passover-pipe and valve connecting said pipes, for the purposes set forth.
