IMPROVED MEANSv FOR WORKING SHIPS" PUMPS.

Specification forming part of Letters Patent No. 45.973, dated January 24, 1865.

the accompanying drawings, making a part of this specification, and to the letters of reference marked thereon.

In said drawings, Figure l is a front eleva tim; Fig. 2, an end elevation; Fig. 3, afront view of the main or pumping shaft, showing the gears and ratchetwheels thereon. Fig. 4 is a transverse section of the same. Fig. 5 and 6 are respectively afront and end view of a single ratchet-wheel with the accompanying nxed wheel and the pawls thereon, similar letters referring' to like parts in all the drawings.

The object of this invention is to free a ship or vessel from the water accumulating therein, from leakage or other causes, by causing the rocking or rolling of the vessel to actuate suitable pumping apparatus. To effect this, a heavy weight, oscillating freely within certain limits, carries two toothed segments, each of which operates a gear or toothed wheel, run ning on a sleeve upon the main shaft of tl e machine. By an arrangement of ratchetwheels and pawls the reciprocating motion of the weight and segmental gears thereon imparts a continuous rotal y motion to the main shaft, and a continuous action ofthe pumping apparatus is thereby obtained.

I am aware'that the oscillation ot` a pendulum or weight, deriving its relative motion from the rocking or rolling of a vessel, has been employed to operate ships7 pumps, as in the Letters Patent of Coates and Perry, No. 18,192, and I do not intend to claim as a novelty the actuating-power I employ, but the manner of utilizing the same, as hereinafter more fully set forth.

The construction and operation of my in# vention are as follows:

A frame-work, A A B, iirlnly bolted to thelower deck, D, or to a suit-able platform, supports the rod E, upon which is the sleeve F. A rigid forked hanger, C, is attached to the sleeve F, and supports the weight WV, and the toothed segments H and I. The

cross-pieces B B in the frame-work support the main shaft M, to which are secured by setscrews the wheels P P, each carrying four pawls, p p, pivoted on its inner face. The gears h and t' are rigidly connected with the ratchet-wheels It and R', respectively, by intervening sleeves, and both turn loosely on the main shaft with their respective ratchetwheels. The vibration ofthe weight produces a continuous rotary motion of the main shaft in the following manner: The toothed segments H and I are constantly engaged with the respective gears h and i', and as the segment H is toothed upon the convex face, and the segment I upon the concave face," the gears h and i, will be turned in opposite directions with every oscillation of the weight. The ratchet-wheels R R will move with the gears 7i and z', respectively, and will also be revolving in opposite directions. The teeth of both these ratchet-wheels incline in one direction. and it occurs that as the ratchet-wheels are revolving in opposite directions, whenever the weight oscillates the pawls p p p p on one or the other flange or fixed wheel P P will engage the teeth of its ratchet-wheel, and impa-rt the motion of the corresponding gear to the main shaft, while the other gear-wheel will turn loosely upon the shaft. A fly-wheel, O, on one end of the shaft M insures regularity ofnlotion, and a crank, N, on the other end, operates a pump, S, by the crank-rod T.

I do not confine myself to the method herein set forth of actuating a pump by means of a crank uponlthe main shaft, nor to the use of the pump herein shown, as the methods of applying the power and the forms of pumping apparatus used must be various.

Somd of the points of utility in my invention I conceive to be as follows: First, that it makes available an auxiliary power which has not been heretofore utilized to any extent for the purpose, and by its continuous and automatic action in sea-going vessels keeps them free from bil ge'water without the use of manual labor; second, that as the power is taken from the pendulum at its lower part, and in the line of its most extended motion, everyv full oscillation produces more than one revolution ofthe pumpingshaft, and in a fullsized machine several revolutions, thereby facilitatin g the operation of pumpin g; third, that the main shaft may be turned by a winch or other means in one direction, independently of the pendulum, so that the pumps may be op` erated byhandit necessary; fourth,thet some suitable portion ofthe cargo may be attached to the forked henger sind serve as e pendulum, thereby avoiding the necessity of conveying entre weight.

The segmental gears may be placed on either side or above the freine-Work, and be there actuated bythe Weight.

I do not claim, broadly, the use ofthe power derived from en oscillating pendulum as epplied to pumping or other useful purpose, as the seme is used in the invention of Contes and Perry, before mentioned, and in the invention of J ames Armstrong, Letters Patent No. 32, 38; but

What I do claim as my invention, and desire to secure by Letters Patent, s- Y Operating the pumping appara-tus of n ship 0r vessel by means of an oscillating Weigh t, in combination with the mechanism deseribcd, the Whole arranged snbstantiull y as set forth.
