Specification forming part of Letters Patent No. 170,680, dated December 7, 1875; application filed August 25, 1875.

To all whom it may concern:

Be it known that I, WILLIAM MOBARNARD, of Clarksville, in the county of Butler and State of Iowa, have invented an Improved Pump, of which the following is a specification:

My invention is a pump specially adapted to elevate water from a well in a continuous forced stream by rotating a shaft. It consists in arranging and combining a reservoir, a series 0f cylinders and pistons, a receivingchamber, a wellltube and air-chamber, and a rotating shaft carrying a grooved cam, as hereinafter fully set forth.

My drawing is a perspective view, illustrating the construction and operation of my invention.

A represents a metal reservoir, the basepiece ot' my complete pump. B is an induction port or tube at the center and bottom of the reservoir A. O (l is my receiving-chamber, corresponding in form and size with the reservoir A. Nos. l 2 3 represent a series of independent pump-cylinders made of metal,

-Wood, glass, earthenware, or any suitable material. They are :fitted and fixed between the reservoir A and the receiving-chamber C, Which tWo parts are rigidly connected by means of suitable rods or screwbolts being passed through the flanges. These cylinders connect the two water-chambers A and C, and the pistons operating in the cylinders lift the Water from the reservoir to the receiving-chamber, hand from thence force it up through a Wel1tnbe.

D represents the cover or platform of the Well. E is a well-tube rigidly attached to the top and center of the receiving-chamber (J. It passes up through the well-cover D sufciently high to discharge the water in the manner of a common pump, and to support a driving mechanism. The tube is secured to the platform or cover D in any suitable Way. a, a is a rotating shaft passed through a suitable stufting-box at the l[op of the tube E, and then down through the tube and the receiving-chamber C, where it rests in a bearing in the center of the base-plate of the chamber C. b c are common bevel-gear wheels supported in a suitable bearer, d, rigidly at c is rigidly fixed to the top of the shaft a a. g is a grooved cam-wheel rigidly fixed to the shaft a, and in a central position in the receiving-chamber C. It stands at an angle relative to its shaft, and its inclined groove may be termed a double inclined plane. m m represent studs or anti-friction rollers in the groove of the cam g. They are rigidly connected with the piston-rods n, which carry the pistons up and down in the cylinders l 2 3. The pistons have suitable valves for the passage of water, and are directed in suitable grooves or guides r, attached inside of the Wall of the chamber C.

In the practical operation of my pump the bevel-gear Wheel b may be turned right or left by a crank, a pulley, or drive-wheel on the same shaft, operated by hand or any suitable power to rotate the mating wheel c and the shaft a. The grooved cam-wheel g, rotating With the shaft a, Will alternately raise and lower the anti-friction rolllers m, and thereby, through the connected piston-rods it, impart a reciprocating motion to the pistons in the series of pump-cylinders 1 2 3. The pistons will be thus actuated independently and successively to elevate Water from the reservoir A to the receiving-chamber C, and their concerted action will force a continuous stream upward through the tube E to be discharged therefrom by means of a colnmon spout, s. That portionof the tube E above the spout s, closed air-tight at its top by means of the stuft'- ing-box, through which the shaft ot passes, be-

comes an air-chamber to aid the pistons in forcing the water from the Welltube, and. makes the tube E a combined Well-tube and air-chamber. Suitable hose may be attached to the spout s, for throwing the Water when desired.

I am aware that a series of cylinders and 'pistons have been used to pump a continuous stream, and that a cam-wheel having an inclined groove has been used to actuate the pistons in succession to force the Water successively through the same num ber of connect ed cylinders in a continuous stream.

I am also aware that in a double-acting pump, wherein two pistons are actuated by an oscillating arm, a reservoir, two cylinders, a

tached to the top of the tube E. The Wheel receiving-chamber, and a combined waterf; wessi) j tube and air-chamber arecenneeted to'lift and A, the-series of cylinders and-y pistons 1 `2 3,

But l claim that my combinay"the reeeiving-chamber C, thecombined welltion7 wherein a rotatin g shaft passes through tube arid air-ehamberE, and the rotating shaft the entire length of the well-tube and air. a, carrying the grooved cam g,substantially as chamber,v is new and greatly advantageous, in and for the purposes shown and described.
