To all whom it may concern:

Be it known that we, LoUis S. MATHEUS and CHARLES LEINDECKER, citizens of the United States, both residing at Lawrenceburg, in the county of Dearborn and State of lndiana, have invented certain new and useful lmprovements in Compressed -Air Apparatus for Elevating Liquids, of which the following is a specification.

Cnr invention relates to that class of liquid-elevating mechanism wherein compressed air is forced down into a well or other like situation, the air being distributed through the water, and the escape of the compressed air forcing up the water in the elevator casing.

The invention has for its object the improvement of the head or chamber by which the air is distributed to the water in the well, whereby the compressed air can be introduced into the air chamber or head at the top, side or bottom of the latter, as is deemed most convenient, or as required by the necessities of any particular case, and whereby a more uniform or even pressure at the point of distribution of the air is secured.

A further object is so to form the outlet end of the distributing head or chamber that the air when leaving the chamber is forced out and up into the well. in an evenly distributed stream, thus raising the water and forcing it out of the top of the well.

A still further object is to so construct the head that one or more of these heads or chambers may be placed one above the other and connected to the same air introduction pipe so as to distribute compressed air at different heights in the well, all of these heads or chambers being operated by one air line. The use of a plurality of lifting chambers better enables the apparatus to raise water from shallow wells.

The invention consists in the arrangement of parts and the peculiar details of construction set forth in the accompanying specification and more specifically stated in the claims appended.

For a full understanding of the invention and the-merits thereof, and to acquire a knowledge of the details of construct-ion, reference is to be had to the ronowinndescription and accompanying drawings, in which:

Figure l is a section of a well or the water-elevating stand pipe therefor, said sta-nd pipe being broken away to show the air-introducing means; Fig. 2 is a fragmentary section of a stand pipe of the kind shown in Fig. l, but provided with a plurality of lifting chambers or heads; Fig. 3 is a longitudinal diametrical section of the head shown in Fig. l; Fig. 4 is a top view thereofyFi'g. 5 is a section on the line 5-5 of Fig. 3; Fig. 6 is a perspective view of the valve or disk which rests upon the upper end of t-he head; and, Fig. 7 is a fragmentary vertical section of the upper end of the head or chamber with another form of valve thereon.

Corresponding and like parts are referred to in the following description and indicated l in all the views of the drawings by the same reference characters.

Referring now to Fig. l, A designates a stand pipe which may extend down into a well of any character, or into a reservoir from which water is to be lifted, the lower end of the pipe being of course open for the admission of water into the pipe. The upper end of the pipe is provided with the union B` of any suitable character from which an outlet pipe C leads. rThe upper end of the union is formed with a head D which supports and through which passes the compress-ed air inlet pipe. The construction described is common to pumps of this class and requires no further description. Passing downward in the stand pipe A is the compressed air inlet pipe 2 which at its upper end is connected to any suitable source of compressed air, and is provided above the union B with a stop cock 3, whereby the passage of air may b-e entirely closed off, and a regulating cock or valve 4. The lower end of the air inlet pipe 2 is connected to a headV or chamber 5 shown in section in Fig. 3.

The head or chamber 5 is preferably cast. in one piece, and consists of the walls 6, these walls being formed at the bottom and at the side with openings 7 and 8 which may be closed by the screw plugs 9. These openings are screw threaded for the attachment of the air inlet pipe to the bottom or side of the chamber 5, as desired. When not connected to the air inlet pipe, however, they are blanked or plugged by means of the screw plugs 9. The head 5 is also provided with the screw studs l0, whereby the head or chamber as a whole may be centered in the pipe A. The upper end wall 1l of the In the form of our device shown in Fig. 3,

Y the lower end of the nipple 13 is smooth as at 15, and surrounding this smooth lower end and movable thereon is the'disk 16 the Y lower face of this diskbeing beveled rom Vthe center thereof outward and upward.

The disk is annular and surrounds the nipple 13, and is capable of movement thereon. The upper face of the disk is provided with the opposed upwardly projecting studs 1T shown in Fig. 6, these studs being fiat on the inner faces to engage with the fiat faces of a nut 18 which is screwed rupon the nipple 13. By adjusting this nut 18 to any desired position upon the screw-threaded portion of the nipple 13, the disk 16 may be limited in its upward movement so that it cannot'open more than a certaindistance away from the face 14 of the upper end of the chamber 5.

j In order to prevent anymovement of the Y nut 18, we also provide the set nut 19 which thus locks the nut 18 in place when once adjusted and prevents any shifting. The object o making the disk 16 so thatr it is mov'- able'up and down upon the lower end of the nipple 13, is'to provide means whereby the upper face of.. the head `may be protected when the device is not in use, and prevent the deposition of sand Yor other matter upon the'upper end of the head. Of course when compressed air is escaping from the chamber 5 by means of the slots 12, the disk 16 will be raised to the position'shown in Fig. 3.

In Fig. 3, the upper end of the nipple 13 is connected to a coupling 20 which in turn is connected to the air-conducting pipe 2Q If, however, the air 'conducting pipe 2 enters the side or bottom of the chamber 5, the open end of the nipple 13'is closed by a `plug 22, Yas shown in Fig. 2. Of course, in

order to attach the air inlet pipe 2 to the sideror bottom of the head 5, it is necessary to provide the pipe 2 with elbows 23 and nipples 24 which have screw-threaded engagement withthe openings 7 or 8.

Thile preferably the disk 16 is movable so that upon the cessation of compressed air entering the chamber 5 the disk 16 will close against the upper end of the chamber, yet we may form vthe disk 16 so that vit has screw-threaded engagement with the nipple 13, as shown in Fig, 7. In this figure, the disk 16 is formed with an upwardly projecting hub 16', the inner face of the disk and hub being screw-threaded for engagement with the screw threads of the nipple. Thus, the disk is formed like a nut and may be turned up or down upon the nipple, it being held locked in place by means of the lock nut 19. Both these constructions, however, permit t-he disk 16 to be adjusted nearer to or farther from the beveled end of the head 5. It will be seen from the drawings that the bevel of the face of the disk 16 has the same angle as the beveled face 14 of the head.

While the construction which wc have described permits the air inlet pipe to be secured either to the bottom, side or top of the head 5, our construction also permits a plurality of heads to be used, as shown in Fig. 2, the heads, however, are of precisely the same construction as heretofore described. Where a plurality of heads are used, however, the air inlet pipe 2 enters either the bottom or the side of the lowermost head, and a vconnecting pipe 25 is used, which is engaged with the nipple 13 of one head, and leads into the screw-threaded opening 7 in the bottom of the head next above it. Thus, our construction permits of a plurality of heads being used, as well as the use of one head, and thus our device is adapted to many different conditions.

.In order to illustrate our construction clearly, the proportions of the diameter to the length in the head 5 have been varied. As a matter of fact, where the stand pipe A is six inches in diameter, the head 5 should be three inches in diameter and about lifteen inches long. It will of course be obvi ous, however, that these proportions might be changed in any manner to best fit the heads for their work, without departing from the invention.

The operation of this liquid-elevating apparatus is as follows: The tube A being filled with water above the level of the lowermost head 5, compressed air is forced into the tube 2, passes downward into the head or heads 5, and issues from the annular space between the face 14 and the beveled face of the disk 16. The issuing air, by reason of the peculiar form of the disk 16 and the face 14 of the head, has the form of what may be termed an annular jet or sheet, and the air when issuing therefrom, is forced out and up into the well, and evenly distributed therein, t-hus raising the water and forcing it out of the top of the well. The even distribution of compressed air in the water is one of the important elements of this class of devices, and we have found in practice that the peculiar form given to the upper end of the head and to the valve, is peculiarly efficacious in so distributing the compressed air through the water as to secure an easy lifting of the water and a maximum of suction.

Our device is extremely simple, has no internal parts, and therefore cannot readily get out of order. It provides for the attachment of the air inlet pipe in a plurality of places, thus permitting of variations to suit particular circumstances, and it is so constructed as to permit the device to be used in casings varying in internal diameter, the device being centered therein by the studs 10. rllhe device forms a unit which may be multiplied to any extent desired, so as to provide a plurality of lifting' heads, and the movable valve or disk 16 permits the issue of air in the form of an annular sheet, but protects the upper surface of the chamber when the apparatus is out of commission. rlfhis filling of the air chamber with foreign matter, and the consequent clicking upof the air passages, is sometimes extremely inconvenient and detrimental to the proper action of the elevator.
