WATER-ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 268,086, dated November 28, 1882.

l Application filed August 17, 1882. (No model.)

.To all whom it may concern Be it known that I, ANDREW J. ENGLISH, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Water-Elevators; andI hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, which form a part of this specilcation.

The nature of this invention relates to certain new and useful improvements in waterelevators of that class where the water is raised by the pressure of the-piston working by gravity upon its downward stroke, and is elevated in its forward stroke by artificial means.

The invention consists in the peculiar construction, combination, and operation of the parts, as more fully hereinafter set forth.

Figure l is a sectional elevation of a well with my elevator. Fig.2 is a cross-section on the line X X in Fig. l.

In the accompanying drawings, which form a part of this specification, A represents a well or cistern, and B represents the top thereof, at or about the surface of the ground.

C represents a tubular pump-barrel, made of any vsuitable material, although the peculiar construction of my whole device enables wood to be used for this barrel with just as much efficiency as though made of iron. The bottom of this barrel is provided with a clap-valve, through which the water is admitted. In the drawings a suction-pipe is added, which, when desired, maybe attached to the top of a drivewell tube, the pump itself being lowered into the ground a sufficient distance to bring the upper operating parts within easy reach. This barrel is provided with a bottom, D, suspended by means of the bolts b and d 'rom the yoke E, which in turn is supported by bolts c from the platform B. The bolts b d secure the head F of this barrel to the bottom and to the barrei itself. A hollow piston, H, of a snfiicient smaller diameter than the interior of the barrel C to leave an annular space, c, between the two, and with a tigbtbottoxn, reciprocates within the barrel, and is lled with stone or any other suitable material to give it great weight, and if more weight is required to lift the column of water desired additional weights, G, may be attached in the manner shown in the drawings, outside the pump-barrel. At or near the lower end of this hollow piston there is secured a cup-leather, j, which, before the piston is inserted in the barrel, is of much larger diameter than the interior of such barrel, and immediately above such leather ring there is secured around the piston a rubber gasket, g, the two rings forming a packing for that end of the piston, of such a character that the water-pressure from below will force water upward into the annular space c, between such piston and the barrel, and a similar arrangement of rings, (the upper leather ring preferably being cone-shaped,) reversed, however, in position, is secured near the top and upon the inner side of the barrel to form a packing at that point which will prevent the water in the annular space e from escaping upward. By this arrangement of packing the piston is always kept in working order and never becomes drya condition which prevails in other devices of this character, and which renders it necessary frequently to charge the pump by pouring water in from the top, wet and soften the upper valve and make it opera tive, for there are none of them provided with the annular space between the piston and barrel adapted to operate as and for the purposes of this invention. v

1u order to prevent'an undue water-pressure iu the annular space, I provide a pipe, d', lead ing from the upper portion thereof' and connecting by a suitable T-coupling with a verti cal pipe, I, provided with a valve, h, at its upper end, through which any-air that may be found in the annular space e may escape. This pipe extends downward and enters the bottom of the barrel O to allow any over-pressure ot' water to escape and return to the barrel below the piston. This piston is attached to a rope, J, secured to and running over the windlass K, which is operated by the crank L and gilt-connections. This windlass is .provided with a clutch, M, actuated by a lever or treadle, N.

In practice, the piston, being attached to the windlass and at the bottom of the barrel, is elevated so that the bottom of thepiston comes nearly to the top of the barrel by means of the windlass, and as the packing of thepiston is suficiently tight a suction is created, which lills the barrel with water up to the bottom of the pistou. The clutch M is then disengaged,

IOO

so that the piston has no support from above.

A water-delivery pipe, 0, leading from the bot tom of the chamber upward, affords a means for carrying the water to the point where it is desired to discharge the same, and vthis pipeis supplied with a suitable valve, P, which, when opened, allows the water to be discharged by the descending` force ot' the piston. When a sufcient amount of water has been drawn the cook is closed and the descending motion of the piston arrested, to be resumed whenever the cock is opened for obtaining1 more water, and this operation is repeated until the contents of the barrel are discharged, when the clutch should be re-engaged and the piston drawn upward again to lill the barrel. By this construction and arrangement of parts a waterelevating device is obtained which is always ready for use, never requires priming, and which will discharge a Volume of water only limited bythe size ot' the barrel,byn1eans ofthe downward pressure ofthe piston working' by its own gravity.

WVhat I claim as my invention is- @espec 1. In a pump, substantially as described, the combination, with a weighted piston packed above and below to form an annular waterspace between, with valved air-outlet and water-connection with the well, of a well having inlet-aperture and valve, as set forth.

2. The combination of the weighted piston E, having annular waterspace e, formed by packingf, with the pipe I, valve h, and pipe d', and with the well having valve a and outletpipe 0, as set forth.

3. In a water-elevator wherein the wat-cris elevated by the gravity-pressure of the weighted piston, the combination of the barrel, the piston, the suction and delivery pipe, and safetypipe communicating,` with the annular space between the barrel and piston, the parts being constructed, arranged, and operating substantially as and for the purposes described.
