HARRY BBOUSSEAU, OF NEW YORK, N. Y.

ROTARY PUMP, &c.

To all whom it may concern.-

Be it known that I, HARRY BROUSSEAU, a citizen of the United States, and a resident of New York, borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Rotary Pumps, &c., of which the following is a full, clear, and exact description.

This invention relates more particularly to rotary, pumps having a plurality of cylinders in each of which a piston is adapted to move.

One of the important objects of the invention is to provide a plurality of cylinders mounted to rotate with a shaft, and a second rotary shaft to which the pistons of the cylinders are connected and which is eccentrically arranged with respect to the firstmentioned shaft so that during the rotation of the shafts a relative movement is imparted between the pistons and cylinders to cause a relative reciprocatory movement, and in such a way that the rods connected to the pistons may be mounted upon independent pins and in vertical ,alinement 'thus simplifying the construction of such pumps as ordinarily constructed and overcoming the necessity of connecting all the pistons to a single stationary crank pin.

Other objects of the invention are to provide a plurality of cylinders having a common head and having openings in said head of a smaller size than the cylinders to cause the water in passing through the openings to offer sufficient resistance to force the cylinders and shaft which carries the cylinders toward the discharge side of the casing in order to prevent leakage and to avoid the necessity of having a packing at this point; and to provide a simple and eflicient pump in which a pump runner is provided with curved wings or vanes and which is adapted to counteract the centrifugal force due to the rotary motion of the cylinders which tends to force the water outward, the said runner serving to draw the water through the inlet and to deliver the same to the cylinders.

A further object of the invention is to provide a connection between one side of the casin and the suction side thereof so Specification of Letters Patent.

that any'leakage occurring in the casing on one side thereof may be withdrawn to the other side.

A still further object of the invention is to provide a pump in which the rotary parts of the invention are substantially balanced so as to have an easy and uniform movement.

A still further object of the invention is to provlde a pump in whichpractically n0 packing and valves are required between the several wearing parts, and which parts may be operated by belt, motor, or other driving means. With these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this specification, and will then be pointed out in the claims at the end of the description.

In the drawings, Figure 1 is a longitudinal section, partly in elevation, of one form of pump embodying my invention. Fig. 2 is an elevation, partly in section, of the pump follower or runner and the-cylinder casing. Fig. 3 is a detail view of the annular cvlinder head. Fig. 4. is a vertical seetion, taken on the line IVIV of Fig. 1; and Fig. 5 is a detailelevation of the pump runner.

- While I show and describe the invention as applied to rotary pumps, it will be understood that some of the parts may be used and the invention so modified as to adapt the same for rotary engines, air compressors, and the like, and that while the rods connecting the pistons to one of the shafts areshown as each arrangedupon an independent pin, it will be understood that where two or three cylinders are used, for example, the rods may be held directly on the end of the shaft without departing from the character of the invention.

The casing 10 has a base 11 to which; a boss 12 is connected by an upri ht 13. The boss 12 has a bushing 14 which orms a bearing for a shaft 15, which latter shaft may have a pulley to be driven by a belt, or said shaft may be operated by an electric motor or in any other desired way. A pin disk 16 is held to the shaft and projecting from said disk is an arm 17 which 15 connected by a link 18 to the cylinder casing 19, the latter forming a part of a pump runner or member 20 and rotating with said flange which may be rigidly secured to a flange 26 of the pump casing, and on the inner surface thereof may be inclined or conical, as at 27. The runner 20 and lts shaft 21 is held against len thwise move-- ment in the bushing 22 by a co lar 29 secured on the outer end of the shaft 21, the said collar being inclosed'within a cap 30 which has a threaded portion adapted to engage a threaded end of the casing head-boss 23.

A plurality of pistons 31 are adapted to work in a corresponding number, of cylinders 32. These cylinders 32 form a part of the cylinder casing 19 and are radially arranged about the runner 20. A ring 33. is arranged around the outer ends of the cylinders and forms a head for said cylinders. The cylinder casing 19 with the cylinders form substantially an annular body and has the central portion cut-away to ad'aptthe pin disk 16 to project within the same, and arranged on the in disk are a plurality of pins 34 arranged circumferentially about the shaft 15, said pins having their outer ends held in a disk 35. There aresix cylinders shown though this number may vary,

and each cylinder has its iston 31. Each piston 31 is hollow and as a pin 36 to which one end of the connectin rod or link 37 is held, the other end of sa d rod being connected to its corresponding pin 34. The

shafts

15 and 21 are eccentrically arranged with respect to each other and are off-center or eccentric to the extent of substantially.

one-half of the stroke of the pistons. It will be evident that bfy reason of the link 18. connecting the shat 15 to cylinder casing 19 that the two

shafts

15 and 21 will rotate in'unjson, and that by reasonv of the eccentric arrangement of said shafts, the pistons will be reciprocated withinthe cylinders during such rotary movement.

. The'casing 10 is provided with an intake or inlet 38 and a discharge 39. The intake end of the casing is connected to substantially one-half of the cylinders at the lower part of the casing so 'as to takein simultaneously three of thecylinders, and the discharge connects by an enlarged and tubular'part 40 with three of the discharging cylinders. As the pistons are reciprocated, as already explained, the water or other liquid or material will pass from the intake to the three lower cyhnders and drawn therein during the rotary movement of the

shafts

15 and 21, at which time the pistons of the three upper cylinders will be moved to discharge the material or liquid from said ,upper cylinders into the enlarged part 40 and to and through the dischar e 39. The rotary movement of the cy inders will have a tendency to throw the water outward owing to their speed and to centrifugal force, and such action of the cylinders. is counteracted by the pump runner or member 20. The pump runner 20 has aplurality of vanes or wings 41 which are so arranged that during the rotary movement of the runner the water will be drawn from the intake and delivered to the cylinders in such a way as to counteract the centrifugal force of the cylinders to force the water outward.

The cylinder head 33 has slots 42 substantially less in area than the area of the cylinders, so that during the discharge of the cylinders the said slots will offer resistance to the discharge of the water, and such resistance will lift the head and cylinder casing toward and force the head against that end of the pump casing 10, thereby preventing leakage and compensating for any wear that might occur at the discharge side of the casing should any leakage occur between the cylinder head 33 and the outer periphery of the runner by reason of said head being forced against the surface of the outer stationary casing, such leakage would be back to the intake side and would not interfere with the proper operation of the pump. The construction just referred to is designed to reduce leakage in the discharge or pressure side of the pump.

If leakage should occur from the intake side of the casing to the sidej43 of said casing, a pressure might be created therein sufiicient to force the face 28 of the runner hard against the inclined or conical face 27 of the head 24 and be otherwise objectionable. To avoid this, a pi e 44 has one end connected to the part 43 o the casing on the opposite side ofthe cylinders and this pipe has its other end connected to the intake portion so that during the action of the pistons any water or other fluid or material that might pass to the side 43 of the casing is withdrawn therefrom and forced by the pistons into the discharge.

From the foregoing, it will be seen that a simple and efiicient pum is provided in which the cylindcrs'and t e means for operatin the pistons are 'eccentrically arrange with respect to each other to cause a relative movement during the rotary movement of the pistons and cylinders; that simple means is provided to-prevent leakage; that simple and efiicier means is rovided whereby the centrifugal action 0 the cylinders is counteracted; that said pump is simple in construction and the parts so arelongated inlet. and discharge openings, at

rotary cylinder casing having a plurality of radially arranged cylinders, a runner having blades and counteracting the centrifugal effect of the cylinders, a shaft to which the runner is held, a piston for each cylinder, a second'shaft eccentrically arranged with respect to the first-mentioned shaft, connections between the second shaft and the pistons, and means for operatively connect ing the shafts to rotate in unison.
