Beit'known that I, Devin GAY, of Bath, .in thecounty of -Lincoln and State .of Maine, haveinyenteda nen7 and usefnlMachine'or Pumping Vessels, which is ,calculated to act or `operate on' the vpumps of itselfat sea lby i the motion `of the Vessel, when the vessel v.isnot in motion themaehinemay'be Worked so as to .operate on the pumps ,by a 'leYer or hand-brake.; and l d o Ihereby .declare that the folloWingis a full and exact description.

YToenable othersskilled in the art -to make .and `use .my inyentiomjl .will proceed to de- Scribe its.construction-and operation.

In a vvessel off ordinarySiZe, No. 1 represents two vperpendicular posts, five and a 'half feet long, and nine inches by six at 4the foot,;and six inches square atthe -top,the ,posts to be 4braced with kiron braces The frame may all be madeofiron cfa suitable size, ,-and With such -variations .as may be necessary, .ibut the .description here 'is Wood.

No.2, is a ooteneach post',.of asuitable size. Vhere .the foot of the posts can ,be Vformed into ,the ,Vesseh ,deck Or ,Otherwise `suitably fastened, the footmark 2 will vnot be necessary.

pendicnlar part of the brakes inside; these maybe about siX inches Wide and of a suitable length.

* No. k9, is an iron rod of a suitable size,

Which connects the :perpendicular part of the brakes atthe top, by afjoint, so as to play aboverthe Wheel, with twoparts or rollers yfixed' and yp rojecting ,out horizontally .at or near the centera suitable Vspace apart-the rod being crooked soas to bring the v,third part ,of Athe lengthin the center are placed across the piece marked 3 With the .perpendicular part inthe center, about @three inches yfrom surfacebf the Wheel, andl fas to add .or diminish Weight, as occasion myll'equire. The Weight'is suspended from .the shaft horizontally, by I ,tWo Vor Amore .arms

,the ,Weight to swingwithinther posts When through which a squarehole is made -to 'fit in the shaft: Itis immaterial Whether the shaft is square or round, if the wheel and weight be suitably fastened-now place the machine so as to bring the end of the brakes over the center of the pumps, and fasten it to the deck by four boltsV through the feet, marked 2, or otherwise-now attach the pump-spires to the end of the brakes-thus the vessel beingY in motion, the weight will swing and move the wheel around, and bring therollers in contact with the brakes, which puts the pumps in operation. The weight may be pulled or stopped by a pieceof iron in the form of abvail, marked 11, with a hole at eachend to play on staples, which are made fastin one side of the cap piece; a notch is made near the center of the bail,

. Vwhich catches on a part projecting up across the center of the weight when it swings on that side, by bearing or pulling down with a rope at the same time-or the weight may be stopped suitably otherwise.

No 12, is the hand brakepof suitable size and length, with a hole in the center to play on a pin or bolt in the center of 'the piece marked 4; and a piece of iron of a suitable size, with two prongs, which are made fast each side of the center, and the other end crooks in a littleand projects down into the space'between the two projectingparts or rollers, on the rod marked 9. For large vessels,'two iron brakes ofV equal Vdimensions of a suitable size, and long enough to give play outside the posts, with a hole in the center to play onabolt which passes through the piece marked Lv near the perpendicular shaft, and the part projecting down, as before described, on the wood-brake, where the two brakes are used. The piece marked t is equal on both Sides, Vand each end of the brake has a socket or hole to put a pole or handle,

through the brakes being placed von each side, and the rod marked 9 so varied as to have both sides alike, will give a more equal bearing than a single part; thus byworking vthe end of the brake up and down, puts the pumps in motion. When the handbrake is used, the weight should be stopped on the opposite side, andremove one roller which vbears against the perpendicular part of one brake. Wien the weight or wheel is in motion, the hand brake should be clear of the rod marked 9. 13 is the pumps about a foot above the deck. I make a fender, of sheet iron or `any other suitableA material, of a suitable width, which forms a circle for the weight to swing within, ,and suitably fastened to the posts. It may be made in two parts, so as to unship one or both parts as occasion may require. When the hand brake is used, as thebooin on board some vessels will prevent the machine being high enough to give it play.

Voutside the post.

A wheel or roller made of'cast iron made of suitable size, with a. bevel on the surface so that the wheel will lean toward the center may be applied to put the machine in operation instead of the weight, by making a circular' Aplatform of plank or other suitable material, about siX feet in diameter, laid fon the cap piece, supported by cross pieces and iron braces, as suits the builder, then the shaft extends up through the platform so as to fit on an iron lever of a suitable size and about three feet long, with an axle or journal turnedrto lit on the wheel, so as to play on the end near the surface of the platform. Thus when the vessel is in motion, the wheel will roll around on the platform, which will have the sameeffect on the pumps as that of the weight.

To stop the wheel orA roller on the platl through the platform near the other hole inside the chocks, then two holes opposite within where the wheel passes; then take a line or rope of suitable size and length and reeve the ends up through the platform inside the chocks, leaving the bite of the rope outside the posts, then make a knot of a suitableV space from the bite in each part of the rope, then reeve the ends through the chocks and draw the knots up, then make a knot on the outside of the chocks, then reeve the ends through the opposite holes in the platform and fasten the ends together There may be sheaves or pulleys fixed in suitable places to make the rope render easy. Thus by drawing the of the eccentric wheel for giving motion and action tothe pistons of the pumps by the rolling or pitching of the ship or vessel at sea or in rough water, and` combining therewith a hand lever for working the pumps by hand when the ship has not suficient motion.
