Application led Apri1'3, 1916. Serial No. 88,734.

To all/whom z't may concern:

Be it known that I, AUSTIN JOHNSON, a citizen of the United States, residing at Grand Ledge, in the county of Eaton and State of Michigan, have inventedl a new and useful Improvement in Pumps, of which the following is a specification.l

My device relates to pumps and more'particularly to that kind of pumps adapted to be inserted in the casing of drilled wells, and'in which a three-way device is employed for the purpose of permitting water to flow out of a spout located at or near the pump, o1' if desired,-t0 cut ofi' the Water from the spout and force it through. pipes to a tank or any other desired locality. Its main purposes are to make a device that shall be easy to install, maintain and repair without digging a pit down to the level of the three-way device, and that shall also provide proper means for the prevention of freezing and the drainage of surplus water.

I attain these purposes by the means shown in the accompanying drawings in which Figurevl is a vertical section ofl a pump in which my device is employed, the

lower cylinder being omitted,` as it may be of any ordinary construction and forms no part of my present invention; Fig. 2 is a detail showing a modified construction of the drainage device.

Referring more particularly to the drawings, 1, is the outer well casing proper of the well itself in which the device is mounted; 2 is a pipe connecting the upper cylinder 3 with the lower cylinder and 4 is the pump rod extending from the pump handle 5 through the upper plunger 6, to the lower plunger; these parts of the pump are substantially the same as are employed in ordinary differential cylinder force pumps and may be modified in any way without departing from my invention.

My device proper consists'of a pipe 7, somewhat smaller in external diameter than the casing 1. This pipe is provided with a right handed screw thread at one extremity and a left hand at the other. A head 8 is adapted to screw on the lower extremity of the pipe 7 and is provided with springs 9, adapted to engage the inside of the casing 1. A second head 11 is screwed on the upper extremity of the pipe 7, and rubber packings 10 and 12 surround the pipe 7, immediately in contact respectively with the heads 8 and 11. A grating 13,

wedge shaped at its two extremities, is

4mounted on theoutside of the pipe 7 in such oppositey direction, the pressure on the packings .will be released and the device may be readily withdrawn through the top of the casing 1.A Water openings 14 are formed in the side of the pipe 1 between the packings 10 and 12 so as to permit the water entering the pipe 7 to escape into the space between the pipe 7 and the casing 1, and thence through the opening 15 into the pipe 16 through .which itis carried to any desired locality. A second pipe 17 extends from the head 11 upto and into the base of the pump; this pipe is practically an extension of the pipe 7. :The upper cylinder 18 is connected by a pipe 19 with the upper extremity of the pipe 17, along screw 20 being employed for purposes' of adjustment as will be more fully explained farther on. The lower extremity of the upper cylinder 18 is closed by a packing end 21, provided with passages 22, 'adapted to engageV with upper and lower seats 23 and 24 respectively. For the purpose of drainage and air 'circulation a pipe 25 opens into the outer casing above and below my device serving to permit the circulation ofA air into the casing vo-f the well and also to drain awaywater from that part of the outer casing above my device. This pipe is of very smalll diameter. In the large sizes, where the outer casing is of sufficient diameter," the pipe 25 may be mounted inside the outer casingas shown in Fig. 2, but its operation is identically the same in the two cases. 26 is the spout of the pump and opens out of the pipe 17 or, lif desired, out of the base of the pump in such manner as to connect with the pipe17. Forl the purpose of connecting the pipe 16 with the casing l, a pipe saddle 27, is secured in anyV desired manner to the outside of the casing 1 and prevented from leaking by packing 28. The pipe 2 is extended upward through the head 8 inside of the pipe 7 and has its upper extremity formed into a seat at the head 21.v

The operation of my device is as follows: in order to mount my device in the well, it

is lowered into the outer casing and the upper extremity of the pipe 17 is attached to the body or base of the pump. The pipe 17 is then revolved in any desired manner, preferably by turning the pump body. The head 8, however, is held stationary within the casing by the springs). rlhe effect of this is to screw the head Steward the upper extremity of the pipe 7 and at the same timethe upper head 11 downward toward the lower extremity of the pipe 7, and thus force the vwedge shaped extremities of the grating 13 under the packings 10 and 12 and expand them against the inside of the casing 1 so as to entirely shut off the space inside of the casing 1 and outside of the pipe 7 between the packings so as to form a chamber between the two.

Suppose now it is desired to draw water through the spout 2G. The pipe 19 is turned by a head 2f) or any suitable manner so as to force the head 21 downward against the lower seat 2li. frs the water rises into the pipe 2 from the lifting cylinder below it can not enter the space 30 between the pipe 7 and the casing 1, being shut off by the head 21, and therefore rises through the passages 22 in the head 21 and flows upward into the pipe 17 outside of the upper cylinder and the pipe 19 and escapes through the spout 2G. 1f it is now desired to shut oli the spout 26 and discharge the water through the pipe 16, the pipe 19 is screwed upward by the head-29 so as to bring the head 21 against the upper seat; 'the water is thus prevented from escaping from the pipe 27 but flows outward over the upper edge of the seat 2st around the pipe 2 into the space 30, thence outward through the openings ld, the grating 13 and the saddle 27 into the pipe 16.

I claim as my invention and desire to secure by Letters Patent:

1. rlhe combination in a pump provided with upper and lower cylinders and adapted to be inserted in the casing of a drilled or bored well, and a pipe connecting said cylinders, of' a water chamber surrounding said pipe and provided with screw threads at its extremities; mounted on each of said threaded extremities, the 'lower extremity thereof being provided with means for engaging with the inner side of the well casing so as to prevent revolution; packing rings mounted near the extremities of said water chamber and adaptedv to close the space between said chamber and said well casing; a perforated a collar operatively collar vsurrounding said water chamber bctween said packing rings and provided with wedging extremities adapted to force said ring into engagement'with said well casing, and means for revolving said water chamber within said casing.
