Letters Patent No. 111,536, dated February 7,1871.

IMPRVEMENT IN HYDRAULIC APPARATUS.

The Schedule referred to in these Letters Pate-nt and making part of the same.

To all whom, it may concern;

Be it known that I ,GEORGE H1 HERRING, of Durand, in the county of XVinnebago and State of Illinois, have invented a new and useful Improveincnt in Apparatus for lifting or Forcing Water and other liluids, of which the following is a full, clear, .and-exact description, reference being had to the accompanying drawing forming part of this specification, and which represents a sectional elevation of an apparatus, constructed in accordance with my invention.

My invention, which l designate a self-acting forcepump, is mainly designed for forcing water in large or small quantities' to an altitude above the level of a running stream or fall by thepower of the latter as derived from the weight of the water in an accuniulative manner, by causing y the stream to supply a tank capabie of rising and falling under the control of -a counter-balance, andso that the tank after' it has received a certain load or charge of water overcomes the counter-balance and descends and automatically discharges itself into a well or chamber that has arranged within or connected with it a force-pump, the plunger of which is operated by the tank, said pump drawing the water from the well into its barrel and discharging it therefrom alternately'by or,dur,ing the movement of thetank, as the latter is controlled in its down-stroke by the weight of the water within it, and in its `11p-stroke after having discharged its con- `tents by the action of the counter-balance.

Referring to the accompanying drawing- Arepresents a running st-reamv or trough-receiving water from a head or fall, the height or depth ot' which may be. varied, or the .supply may be obtained` from a spring.

B is the power-tank or receiver, into which the water from the trough A enters.

This tank is suspended by -a rope orchain, C, arranged to pass over a pulley, D, and having attached to its opposite end a counterbalance,.E, which is of sufficient weight to elevate the tank, when empty, and with it the plunger F or working mechanism of the pump GL Said tank is fitted with a valve., b, openingv inward, or that is kept closed while the tank is receiving water, and which is only required to be opened toward the close of the down-stroke of the tank.

H is a well, in which the plunger G is placed, and

I, the discharge-pipe from the pump, leading torany desired height or distance.

J is an overflow for surplus water from the well. .Vater accumulating from the stream in the 1re# cciver B causes the'latter to descend,`and with it the plunger F, so as to force out thc water from the pump-barrel up to the discharge-pipe I.

As the tank and plunger, however, approach the end of their d0wnstroke,'the valve l) `comes in conltact with a stop or lifter, c, which opens s'aidvalve Ycut ott from entering the tank by means of a gate, d,

which is lifted oropened by the tank toward the close of the top strokeof the latter, andremains open till the tank is sufficiently loaded tovbegi'n its succeeding down-stroke.

In this way is an automat-ic action kept up without the aid ofwheels or complicated gearing, anda portion of the water furnished by the stream may be forced to any desired height above the level of the Vstream,tliis result, too, being irrespective of the head or fall variation ixrwhich will only affect the velocity at which the apparatus 'works or quantityl'of water delivered in a given time.

The pulleyD it is preferredto make of such a shape that the tank will descend with an accelerated motion, so as to insure its descent and opening cf the valve b, and said accelerated motion afterward made available, through the' operation of thccounter-lmlance, to carry up the tank with suticient force to open thc gate d for a fresh suppl y to the receiver or tank. l i

In cases where a high head ot' water' is available, then instead of the pump-,plunger being connected in a direct manner by `1'od with the power-tank, the connection may be made through the intervention of a lever.

Likewise, it" desired, two pumps may be used with a power-tank to 'eacl1,and a beam or "lever connecting them, so that they act in common, and alternately in reverse directions, and operate each as a counter-balance to the other, thereby dispensing with a separate counter-,balance or weight.

XVhat is here claimed, and desired to be secured by Letters Patent, is f l. A pump, the piston of which is operated in its down-stroke by the weight of water in a tank connected or supported on the piston-rod, said tank being provided with a valve' so arranged as to be opened by coming in contact with a projection, c, to canse said tank to discharge its contents into va Well or reservoir, in combination with a counter-balance, by

which said piston is raised when the contents of the Y tank are discharged.V

2. Combination and arrangement of the tank ]3, provided with avalve, b the pump G, and .its` piston F, cord or' chain C, pulley D, counter-balance E, and flume-gate d. for-operation as herein described.
