TED STATS JOHN I. CARR, OF MATTAPOISET, MASSACHUSETTS.

PUMP-GEARING.

Specification of Letters Patent No. 24,193, dated May 81, 1859,'.

To all whom it may concern:

Be it known that I, JOHN I. CARR, of Mattapoiset, in the county of Plymouth and State of Massachusetts, have invented new and Improved Pump-Gearing for Operating Ships Pumps; and I do hereby declare the following is a full, clear, and eXact description of the construction and operation of the same, reference being had to the annexed drawing, making a part of this specification.

Figure l is a perspective View. and is all the drawing requisite to illustratev my invention.

A represents the deck of the ship; B1 B2 B3 a railing around the pumps and mainmast, which is supported by the posts b1 b2 b3 b4, and to which is affixed the machinery constituting my invention; C1 C2 the pumps; D1 D2 multiplying gear wheels; ElL E2 iiywheel; F1 F2 cranks which need no further specication.

G is a horizontal rockingbeam, permanently secured to the center of the shaft K2, connected also at each end in movable joints with the p-istons J1 J 2.

H is a lever secured in its center to the end of the shaft K3 at a and at right angles with the beam G, and also connects, in movable oints, at each end, with the connecting rod I1 I2 at a2 a2.

K1 K2 are the multiplied shafts, to the ends of which are secured the cranks L1 L2. These cranks are also connected with movable joints with the connecting rods I1 I2 at a2 1.5.

I4 is a connecting rod which operates always in a horizontal manner, and connects the two multiplied shafts by means of the cranks L3 L2, causing the shafts K1 K2 in conjunction with the lever I-I. Cranks L1 L2, and connecting rods I1 I2 to revolve with the same velocity, and also cause the resistance on the cranks F1 F2 to be equal.

Operation: By turning the cranks F1 F2 the fly-wheels are caused to revolve and consequently the shafts K1 K2 are also revolved. By means of the cranks L1 L2 on the shafts K1 K2, the connecting rods I1 I2 cause the shaft K2 and consequently the beam G to assume a rocking motion. The two fly-wheels E1 E2 are caused to rotate with equal lvelocity by means of the connecting rod I2 and the cranks L3 L4. The power vof the operators at the cranks Fl F2 being accumulated in the iy-wheels is disposed in regulating and causing the even working of the pumps.

The rocking beam Gr and the lever H may be considered a lever, the journals of the shaft K its fulcrum. The pistons, connecting rods and cranks, being properly constructed and of uniform dimensions, as shown by the drawing and model, there are no dead points; the resistance is equal 'on the pumps and the labor of the operators is uniform. Either pump may be disconnected, or the cranks Fl F2 turned either backwards or forwards and the result is the same. l

By this invention a quick, uniform, andl powerful stroke of the pistons is attained.

In this petition and specification I do not conine .my invention to operating ships pumps, it may be applied to other pumps. Neither do I confine to securing said machinery to the deck as described, it may be afhxed in any practical manner. Neither do I claim or desire to claim any previous invention for operating pumps; but

What I do claim as my'invention, and vdesire to secure by Letters Patent and to what I do confine myself is- The device, as herein set forth and described, for operating pumps on board v'of ships and in other places where said invention may be useful.
