AIR-EXPANDING WATER-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 762,615, dated June 14, 1904,

Application filed July 24, 1902. Serial No. 116,803- (No model.)

To all whom it may concern.-

Be it known that 1, ANDREW BYE, a citizen of the United States, residing at Butte, in the county of Silverbow and State of Montana, have invented certain new and useful Improvernents in Air-Expanding Water-Elevators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to compressed-air water-lifts, and has for its object to provide an apparatus whereby the expansion of air may be used for'elevating the water.

A further object is to provide an apparatus of the character described which shall be simple of construction, durable-in use, comparatively inexpensive of production, and efflcient in action.

WVith these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, which'will be hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation with parts in section of an air-lift embodying my invention. Fig. 2 is a top plan view of the receiving-chamber. Fig. 3 is a vertical section through the airchest and casing of the slide-valve. Fig. 4 is a detail view of the connection between the outer end of the valve-stem and the rocking lever. Fig. 5 shows a bottom plan view and opposite end views of the sliding and oscillating piston. Fig. 6 is a side view of the piston disconnected from the slide-valve and shows the valve and a portion of the air-chest in vertical longitudinal section, and Fig. 7 is a horizontal section through the piston-casing.

Referring now more particularly to the drawings, the numeral 1 represents the waterreceiver, with which communicates the waterinduction pipe 2, leading from an elevated tank or submerged in the sump-hole, and the water-discharge pipe 3, which is connected at its upper end with the delivery-pipe 4 by means of an interposed throat or ejectorchamber 5.

6 represents a check-valve located in the pipe'2, which controls the flow of water into the

receiver

1, and 7 indicates a float in said receiver. A check-valve 8 is arranged in the base of the pipe 3 and is adapted to allow the water from the receiver 1 to pass into the pipe 3, but to prevent its return.

9 represents an air-chest mounted above the receiver 1 and suitably supported by uprights or columns 10.

11 is a piston-casing mounted on said chest and having arranged therein a sliding and oscillating piston 12, which operates an ordinary D slide-valve 12, which controls the flow of air through ports g, h, and tin the chest to the several parts of the apparatus. An air-supply pipe 13 communicates with one end of the chamber 11 and leads from an airpump or a receiver and is supplied therefrom, and 14 represents an air-exhaust pipe provided at its upper end with a gooseneck bend 15 at its point of juncture with the said throat which is fixed to a rock-shaft 18, to which is connected a crank-arm l9, jointed at its lower end to a rod 20, which is adjustablyconnected at its upper end with a rocking lever 21,.pivoted to a bracket 22, projecting from the airchest 9. To the opposite end of the lever 21 is pivoted an adjustable link 23, which connects said rocking lever with a laterally-projecting arm 2 L, fixed to the stem or rod 12 of the piston 12. Through this mechanism the piston 12 is oscillated bythe rise and fall of water in the water-receiver, thereby covering and uncovering air-ports in thecylinder and casing, allowing air to enter at one end of the cylinder and discharge at the other, or vice versa, to shift the piston 12 back and forth, and thereby shift the D slide-valve, which controls the flow of air to and from the water-receiver. l

The receptacle 1 may be of any desired size and shape; but in the drawings I have shown it as a short vertically-arranged cylinder with a dome-shaped projection 26 on each end for the reception of the float 7 at the opposite I00 ends of its movement. The lower end of the discharge-pipe 3 communicates with the dome at the bottom and the air-pipe 16 with the one on top. The receptacle is preferably supported on a base, as legs 27, which raises it high enough for the curved ends of the pipes 2 and 3. The lower ends of the inclined uprights are preferably seated on top of the receptacle, which thus makes a very compact structure and holds all of the parts rigidly against displacement. The top dome 26 is located between two of the uprights, and a manhole 28 is formed between the other two, through which access is had to the interior of the receptacle, preferably over the rod 18.

'A counterweight 25 is mounted upon the rock-shaft 18 and counterbalances the weight of the float.

The

ports

9, 7b, and 1 in the air-chest 9 corn municate, respectively, with the exhaust-pipe 14, the air-conducting pipe 16, and the airsupply pipe 13. In the pistoncasing are formed air admission and exhaust ports a c and cl cl, the admission-port and its companion exhaust-port (i being arranged on one side of the center of said casing, and the other pair of admission and discharge ports a d are arranged on the other side of the center of said casing. The exhaust-ports (Z d have a common outlet to the atmosphere at f. The piston 12 is slotted to receive the upper portion of the valve 12 and is so fitted as to have both an oscillatory and a reciprocatory movement.

One end of this piston is provided with ports a, 7), and c, and the other end with ports a, b, and c, which ports are formed in the base of the piston and extend to and through the respective ends thereof, as shown clearly in Figs. 5 and 6.

The piston is adapted to operate as follows: Beginning with the position shown in Fig. 1, when the receiver 1 fills with water the float 7 rises and slightly rotates the piston 12 by means of the rock-shaft 18, arm 19, rod 20, lever 21, link 23, and arm 2A, connected to valve-stem 12". This rotative motion brings the port 6, Figs. 5 and 6, over port a, Fig. 7, and at the same time port I) over (2, admitting air under pressure to the left-hand end of the piston-casing and exhausting the air previously taken in at the right-hand end through d and f to the atmosphere. The piston 12 is now driven to the right, sliding the Valve 12 with it, until port 0 uncovers a, admitting air to right-hand end, thus balancing pressures and bringing the parts to rest. Valve 12 is now in its right-hand position, as shown in Fig. 6. Air under pressure now flows through ports 6 and h into the receiver through pipe 16, driving the water through valve 8 into the discharge-pipe 3. The float7 falls as the water leaves, rotates the piston 12 in the opposite direction to that described before, bringing port 5 over a and 7) over (Z, giving pressure to the right-hand end and exhausting the left. The piston now moves. to. the left, bringing the valve back to the position shown in Fig. 1. The air in the receiver now expands and flows back through pipe 16 and port it into port g and thence through exhaust-pipe 14, driving the water above that point out. This completes the working cycle. In order to prevent piston 2 from rotating too far so as to blind its ports, a pin a, Fig. 3, is driven through the valve-chest at c, Fig. 7, passing through a slot 20 in the piston, as shown in Fig. 6. i

The purpose of ports a and a of the piston is to register with ports (Z cl and open to the exhaust in case the piston overtravels, thus bringing it back to its exact place.

In operation the water enters the inductionpipe 2, passing the valve 6, enters the receiving-tank 1, the valve 6 preventing the return of the water through pipe 2. As the tank 1 fills the float 7 rises, and the crank-arm 19, fixed to the shaft 18 of said float, will raise the rod 20 and operate the rocking lever to shift the slide-valve to open the port connection with the air-supply pipe, thereby allowing compressed air to enter the receiving-chamber through the air-pipe 16 to force the water in said receiving-chamber out through the valve 8 into the discharge-pipe. As soon as the water is thus forced out of the receiving-tank the float will lower and will operate the slide-valve through the medium hereinbefore described in an opposite direction to that previously described to close said air-inlet vah e and open the air-exhaust valve to permit the escape of air through the said exhaust-port g and discharge-pipe 14:, and when the air is exhausted from the receivingchamber lmore water will rush in through the valve 6, and the operation will be repeated.

It may be well to state that the capacity of the receiver must correspond with one-fourth of the delivery and the entire exhaust-pipe.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of the invention will be readily understood without requiring an extended explanation.

Various changes in the form, proportion, and details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, what 1 claim, and desire to secure by Letters Patent, is

1. In a water-elevator, a receptacle provided with a water inlet and outlet and an airinlet, an air-chest mounted above the receptacle and communicating with said air-inlet and provided with a bracket, a slide-valve and an oscillating valve for controlling the passage of air through the chest, the outer end of the stem of the oscillating valve being mounted in said bracket, a lever pivotally mounted on the side of the bracket, a link for connecting one end of the lever with said valve-stem, a rod connected with the other end of the lever, and a float in the receptacle connected with said rod.

2. In a Water-elevator, a receptacle provided with a water inlet and outlet at the bottom and an air-inlet at the top, said top and bottom being each provided with a hollow dome-shaped projection, the air-inlet being connected with the top dome and the wateroutlet with the bottom dome, a rock-shaft journaled in the receptacle, a float connected with. said shaft in position to enter said domes at the limit of its vertical movements, a manchest, mechanism for operating the valves,

and a rod from the rock-shaft to said mechanism.
