T0 ALL WHOM -IT MAY CONCERN: l

. Beit known that I, CHARLES W. C Anoon, of Portland, in the county of Cumberland, and State of Maine, have invented a new *and useful improvement in the Propulsion of Vessels; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. l l

Figure 1 represents a side elevation of my invention. Figures 2, 3, 4, and-5 represent sectionalf'views of parts of the same. vSimilar letters of reference in the different figures refer to the same things.

The object of my invention is to applyth'e undulatory motion of the sea to the.lpropulsion of vessels through the medium of pumps.

Also to afford ameans of regulating the movement of the connecting-rods by which the pumps are actuated,

so that the length of stroke ofthe pistons may-be governed.

Also to propel vessels by direct impact of Huid when the propelling streams are made to issue in a daring manner, and to steer vessels thereby.

Also to cause the impelling fluid to act obliquely downwards lto the line of motion of the vessel when being n.

i propelled. i

In order that those skilled in the art may be able to construct my invention, I will proceed to describe it.

A A2,'ig. 1, represent two sea-going vessels, one being forward-of and at a short` distance from the other. B represents a framing extending vertically down by the sides of both vessels nearly to their keels, and reaching from within a short distance of the stem of the forward vessel to within a short distance of the stern of the after one, extending above the tops of the vessels about one-quarter further than below, and being connected at the top by lateral framework. This framing is made of great thickness and strength, and has the lower part which'A enters the water made in `wedge form. It is jointed to each vessel by shafts, vC C, and allowed to vibrate, the. shafts passing laterally across the decks of the vessels about midships Attached to this framing is oth'er framing which passes around the stem of the forward vessel and the stern ofthe after one, having its shape corresponding to that of th vessels, so 4that the entire framing enclosesfboth vessels, allowing them to play inside of it for propulsion by the waves; thelatter framing being represented by the letters :v x. The shafts are also of great strength, andare attached to the framing by caps passing over their endsl with bolts passingv through the sides-of the caps and the shafts, having their rims made very broad and bolted to the framing, the

shafts turning with the framing on bearings attached to the vessels.' D D are'connecting-rods attached to framing B, andto the pistons E E, these. pistons being parts oftwo force-pumps, F F, `on vessel A. G is an air chamber. H H areY induction pipes leading from the outside of the vessel near the stern, to the force-pumps F F. I I are pipes leading from the force-pumps to the air chamberyGrM K K'iare eduction pipes leading from the air chamber G, through the stern and outside of the vessel, running i'n au oblique downward direction, this direction being for the purpose of causing the impact of the fluid towards the most resisting part of the water.

The outlet ends of .these pipes are v flattened and curved, so as to give the streams a Haring form, a longitudinal lateral section thereof being shown in iig. 5,'the straight part being that nearest the stern of the vessel, and the daring part the farthest therefrom, so that a very quick and. decided action will be made upon thev vessel inl steering, as well 'as the exposure of a large -frictional surface in the impact. In these pipes, K K, near the stern, are. placed valves L L, for steering the vessels, these valves being connected with a wheel and pulley, V, on deck, so that each can be operated alternately at the same time; that is, one shut or partially while the other is open or partially. These pipes, K K, are made smaller in' diameter than the induction pipes, sie as to produce rapid streams. s

The operation is this: as the vessels change their relative positions by the undulating motion of the sea, the framing B is caused to vibrate, and the pumps F F to be worked,.drawing the water in through the induction pipes, which are large in diameter, and forcing it outthrough the eduction pipes, which are small in diameter, against the water'outside of the vessels, causing them to be propelled thereby. i

Mrepresets a pipe extending from one of the force-pumps to the other,fhaving a valve, N, in the same, a spout, O, leading therefrom outside of the vessel, for the purpose of regulating the speed. When the valve N is open the pumps will not act to propel the vessels, but when partially open there would be somo action, depending upon the extent of the opening. The spout is to carry off outside of the vessel anyl water that might issue from the valve N. Fig. 3, a represents a force-pump, b the piston, c c two rods jointed to the centre of the piston and extending outwards; d d are two slotted-arches attached to the sides of thepump, and extending upwards from lthe top about the same distance as the length of the pump. e e are two rods jointed to the rods c c, and extending inwards and jointed to the main connecting-rod, D; the'pins which join the rods c c and e e passing through'the slots in 'the arches on bothv sides, causing thev rods to follow the direction of the slots, the lower part of which,.and for about one-third of their length, having an oblique curved course inward towards eachother; after which,and for about one-third more of their length, they have a straight parallel course, and for the rest of their length they have again an inward oblique curved course, so that the piston can be conined to a limit of stroke without regard vto any irregularityof the waves; requiring less length of pumps, preventing unusual strain upon the machinery, or' sudden and dangerous increase of speed; and allowing the use of double-acting pumps when desired. When the waves. are of' the average height the rods will move only in the parallel part of the slots, but when above they will be carried into the obliquepart. P represents a doubleacting trunk engine; Q -a pipe leading from the same tothe air chamber G. Attached to the under side of the piston of the engine P, is a'connecting-rod leading to a crank on a longitudinal shaft, R, on the end of which is a propeller, S, so that the propeller may be used inpropelling the vessels in'conjunction with the streams from thee'duction pipes K K, and the streams be used mainly for steering. 'l represents an ordinary rudder which maybe used in conjunction With the streams. 'U is a pipe for carrying oii` the fluid after it has been through the engine. The operation when the propeller-wheel is used is this: as the undulatory motion of the sea actsl upon the pumps F F, they will draw water from the outside of the vessel, cause it to be forced into the air chamber G, and from thence through the pipe Q, to the engine P, and operating thev engineit will pass into the pipe U, and be carried to the outside of the vessel, the operationof the engine causing the prope1ler-wheel to be revolved and the vessels propelled. v i p Having thus described my invention, I would remark that air may be used `in the pumps instead of water if desired, in which case the induction pipes should open into the air; also, that a common engine governor may be connected with the machinery to regulate its action, either with a valve in the air. chamber or in one of the pipes leading therefrom. I A iiexible pipe may extend from theairchamber on vessel A2, along the framing B, to an engine-on vessel A, the engine being connected with a crank-shaft extending through the stern of the vessel,wi.th a propeller ou its end, so that both vessels may have propellers operated by one set of pumps. I would further remark that in the construction of the framing connecting the two vessels, I recommend that it be made of the best ship timber, and plankin g, in several thicknesses, placed vertically and horizontally, bolted together with great regard to strength, having knees both of wood and iron wherever they can be advantan geously placed, with bolts running' diagonally from the top of the framing to the bottom; the whole work thereon being done with a view of approximating to the same strength in the connections as if the two vessels were one; that is, as strong as a vessel would be of the length of the tw in any'paity of her. If it should be desired to have but little framing above the tops of the vessels, as with naval ships, an armniay extend from the main shaft to which the framing is attached on the after vessel, down into the hold of the vessel, and the pumps F F placed also in the hold horizontally, having their connecting-rods operating the piston attached to this arm, so that as the shaft was turned by the vibration of the framing, the pumps would be operated by the arm,and the vessel'spropelled. The framing in this case could be made' proportionably thicker, and, for naval vessels, iron plated. Auxiliary engines may be upon one or both of the vessels to propel them in and out of harbors.

` What I claim as new, and desire to secure by'Letters Patent, is-

The application of the undulato'r'y m'otion oi" the sea to the propulsion oi' vessels by means .of pumps, and substantially as described. V

I also claim controlling the movement of the connecting-rods by which the pumps are actuated, so that the length of stroke of the pistons may be governed, substantially as described. y CHAS. W. CAHOON.
