Letters PatentNo. 91,045, dated June 8, 1869'.

IMPROVEMENT IN OPERATING SHIPS PUMPS:

The Schedule referred to in these Letters Patent and making part of the same.

To all whom. it' may concern Be it known that 1, ALMON ROFF, of Southport, in the county of Fairfield, and State of Connecticut, have invented a new and improved Automatic Pump- Attachment to Vessels; and I do hereby declare that the followingis a full, clear, and exact description thereowvhich will enable others 'skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a vertical transverse section of a vessel provided with my improved automatic pumpattachment.

Figure 2 is a plan or top view, partly in section, of the same. f

Figure 3 is a side elevation of the same.

'Figure 4 is a detail plan view of the adjusting-lever I of the same.

, to become exhausted, and many vessels were lost because the pumps could not be properly worked.

My invention consists chiefly in the application to the vessel,.of a detachable paddle-wheel, which will be revolved by the motion of the ship through the water, and which will, by suitable connection, operate the ships pump. The wheel can be readily removed when the pumps are not to beused, and as readily replaced when needed.

The device can be applied to all kinds of vessels, even to those which are propelled by steam, and will prove a greataid in all cases of danger from fire,

storm, or leakage.

The invention consists also of various details of construction of parts, as hereinafter more fully described.'

A A, in the drawing, are two horizontal crank-axles, which have their bearings in any suitable part of the vessel, and which have their cranks, a, connected with the piston-rods of two pumps, to operate the same when revolved.

The two shafts A carry toothed wheels b b, as shown.

B is a sliding shaft, having its bearings in the vessel, between the shafts A A, and carrying a toothed wheel, c, which, when --the shaft B is moved outward, will be in gear with the wheels b '1).

The shaft B can be projected through an aperture in the side C of the vessel, which aperture is lined with a box, d, so as to form a water-tight packing.

On the outer side of the vessel is secured, so as to surround partly the aperture i'u the side of the ship, a U-shaped plate, D, which has a groov'e on the inner side to receive a flange, e, that is formed 0n the hollow shaft, or shank f, of a p addle-wheel, E.

The shaft B is squared at its outer end, and the shaft f has a corresponding square aperture'.

When the wheel is to be used, it is placed with its ange, e, into the groove of the plate D, as in figs. l and 2, the plate D being open on top, to allow the insertion of the wheel from above.

The shaft B is then moved forward to fit into or through the shaft f, of the wheel, and to bring its pinion, c, into gear with the toothed wheels b b.

As the ship moves through the water, the wheel E, whose paddles reach into the water, will be rotated automatically, and will revolve the shaft B, and thereby also the shafts A A, operating thus the pumps.

The shaft B may also be square where it passes through the box d, in which case asleeve, g, is tted into said box around the shaft, as shown, to revolve with said shaft.

When the pumps are not to be worked, the wheel E isremoved, and the shaft B drawn in.

The apertureiu the side O is then enclosed by a spring plug, h, which is a double plate, with rubber or otherpacking between its leaves, and which is placed into the groove of the plate D, as is clearly shown in g. 5.

The device for throwing the shaft B in or out may be of suitable construction.- I prefer to use the apparatus shown in the drawing. In this an arm, i, is suspended from the shaft, B, and connected with a slotted crank, j, of a vertical shaft, F, which has its bearings in the vessel, as shown.

The upper end of the shaft F carries a cross-head, K, which is placed into' a countersunk box, G, arranged on the deck H, as shown.

The box can be closed, and the cross-head concealed, by means of a cover, I.

When the cover is removed the` cross-head can be turned, so as to swing the shaft F, to either move the shaft B` inward or outward, as may be desired.

The cross-head can be locked in either position, by means of a pin, l, fitted through it, and through one of two apertures in the bottom of the box G.

Instead 4oftwopump-shafts, only one, or more than two, may be thrown in gear with the operatingshaft B.

Instead of' being a paddle-wheel, the driving-device may be a screw, to be arranged at either end'or side of the ship.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- 1. An automatic pump-attachment tovessels, consisting of the removable paddle-Wheel, or its equivalent, arranged on the side of the vessel, to operate the pump or pumps, substantially as herein shown and described.

2. The sliding shaft B, -when arranged in a vessel, so that it can receive a paddle-Wheel, E, or its equivalent, for the purpose of automatically operating the pump or pumps, as specified.

3. The grooved U-'shapcd plate D, when arranged at the side of a vessehopposite an aperture through the same, substantially as herein shown and described, for the purpose of supporting the hollow shaft of the removable wheel E, or its equivalent, substantially as herein shown and described.

4. The spring-plug h, to be placed into the groove of the U-shaped plate D, for thepurpose of closing the aperture through the side of the ship, substantially as herein shown and described.

5. The vertical shaft F, havingthe crank j and cross-head k, when arranged in combination with the sliding shaft B, countersnnk box G, and cover I, all arranged and operating substantially as herein shown and described;

6. The sliding shaft B, carrying theiwheel E, or its equivalent, and fitted through the box d, when arranged to operate the pump-shaft or shafts A, substantially as herein shown and described.

. The above specification of my invention signed by me, this 5th day of March, 1869.

ALMON ROFF.
