IMPROVEMENT IN RO'l'ARV PUMPS Specification forming part of Letters Patent No. 102,05 7., dated April 19, 1870.

To all whom it may concern:

- Be it known that I, ANTHONY SLUTHOUR, of Cleveland, in the county of Cuyahoga andl State of Ohio, havev invented a new and use-A ful Improvement in Pumps; and I do declare that the following is a true and accurate' description thereof, reference being had to-the accompanying drawings, and to the letters of reference markedthereon, and being a part of this'specitication.

The nature of this invention relates to an improved construction of lift and force pumps;

its various parts, as hereinafter more fully shown and set forth.

Figure l is a rear elevation of my pump. Fig. 2is a vertical longitudinal section of the saine, and Fig. 3 is a bottom plan of the horizontal oscillating piston.

Similar letters of reference indicatev corresponding parts in each figure. v

In the drawings, A, represents ahorizontal cylinder, mounted on suitable legs, and closed byheads a.' Within the cylinder, at its bottom,l are twor longitudinal channel-plates, B B', inclined toward each other at their tops, and connected there and atthcir ends by partitions, forming a chamber, which the' inducb b' are foot-valves, longitudinally hinged to the plates B B', covering their Openings.

D' -s a shaft passing through suitable stuifing-boxes in theheads of the cylinder. E isl arectangular piston, secured to the shaft VD, closely fitting the cylinder at its greatest diameter and between the heads. c c' are clackvalves, hinged to the upper sides of the piston, and cover longitudinal openngsfat either side ot'its axis. F is the eductionfpipe at the top of the cylinder, discharging into ar pitch-- ler-spout, G.

H are levers, secured in any convenient -Vmanner to the ends of the shaft D, and are, in

turn, sleeved in a bail or handle, I, by means to the shaft D and its pistou E. J is a wing.- valve, seated in the eduction-pipe, over which is suspended a movable cup to prevent the Water from being thrown out of the spout.

To operate the pump, the' bail or handle I is moved to andvfro, causing the piston to Oscillate on its axis, when the. valve on the descending side opens, and allows the liquid to pass up through, its pressure closing the footvalve beneath. At the same time the valve 011 the ascending side of the piston closes, and the foot-valve beneath it opens, and Wa- 4ter rushes in to ll the vacuum, and in the rcontinuation'of the movement described a constant upward flow tained.

The edges of the piston may be provided with cup-leathers, and the stuffing-boxes packed, if desired; but it' the parts be propof the liquid will be mainv erly fitted all packing may be dispensgd with,

except a water-joint under the shaft D, which is formed by a groove, d, in the connection between the channel-plates; otherwise the vacuum would be destroyed.

By threading the end of the eduction-pipe and removing the cup K, la hose may bev coupled on and water forced through the same to any desired point.

The valve J serves to keep the pump primed by retaining the Water in the cylinder, but isl not essential to the working of the pump. By

lifting it the pump is emptied, and thus prevented from freezing up in cold weather.

rlhe pump may be operated by power or by hand, or with any other appropriate forms of levers which will produce an oscillatory motion in the shaft and piston. What I claim asv my invention, and desire to secure by Letters Patent, is-

'lhe cylinder A, provided with heads. a,

channel-plates B B', valyes b and b', induction-pipe C, eductiOnpipe F, valvefJ, cup K, shaft D, piston E, valves c ande', lever H, handle I, and disehargespout G, when each ot' said parts is constructed as described, and

all are combined. and arranged to'operate as and for the purpose set forth. i

ANTHONY vSLUTHOUB.
