A short lever arm 3() is pivoted to the end of the lever arm 27 iat the pin 31. A spring shown in dottedy lines is connected to 'the pin 34 mounted on the outer end of the short lever arm 30 and to the pinl 28 upon which the longer arm 27 is pivoted. This spring tends to fold the two lever arms together or to collapse them. This eilort of the spring is transmitted to a finger 35 which when the parts are in the position. shown is held just out of contact with the valve stem 36 ofthe movable valve 37. A stationary stop 38 is mounted near the valve stem 36 in such position that the finger 35 is limited in its movement away-from the valve stem 36 to obtain a reversal of thev action of the spring 33.

The valve 37 controls an admission port 39 and an exhaust port 40. which communicates with the exhaust passage 41 shown in dotted lines. The central space between the ports 39 and 40 communicates by way of passage 42 with the air pipe 10 leading to the pump 1. The admission port 39 com municates with the compressed air supply pipes 13 leading to the main reservoir 2.

The pump cylinder 1 comprises a head member 44 and a foot member 45 between which the barrel 46 is fastened. The head megnber 44 has a socket or connection 47 to which the water discharge pipe 3 is connecte ed. This socket or connection 47 communicates with a passageway 48, the lower end of which passageway 48 communicates with the central pipe 49. The pipe 49 is fastened at its lower end to the valve cage 50 which contains the check valve 51, governing the movement of water in the discharge pipe 3.

A central bolt 52 passes through the foot member and is secured to the lower end of the valve cage 50, thus holding the head 44 and the foot 45 of the pump upon the end of the cylinder 46. The foot member 45 is provided with a foot valve 53 through which the pump is lled after each stroke. The valve passages for the valve 53 are covered by a conical screen 54 at the lower end of the foot'inember 45.

The operation of the system is as follows:

Assuming that the tank 2 is filled with compressedl air and that the exhaust port 4l is open and the admission port 39 closed after the completion of a stroke the pump 1 becomes filled with water due to the exhaust ports 40 being open.

As the pressure in the tank 5 drops due tp the escape of water at an outlet or faucet and as the piston 18 is moved over to the left, as shown in Fig. 5, the toggle arms` 27--30 are moved against the spring until the spring throw the short arm 30 to the other side of eener opening the admission port 39 and closing the exhaust port 40 thus admitting pressure to the pump 1. fis a ccnseeuence the water is driven out et' the pump l through the discharge pipe, part ci' it going to the delivery main 4 and a part into the tank 5. The delivery main should be so proportioned that upon maximum operation ci the system suiicient water will be invariably discharged into the air spring for each pump stroke to raise the pressure sulliciently to operate the pressure icontrolled valve. This raises the pressure in the tank 5, the air losing trapped in the top of the tank driving' the piston 18 to the right as shown in Fig. 5 and causing the spring 33 to move the short lever arm 30 past the center so as to cause the finger 35 to engage the ,stem 36 of the valve 37 closing olf the admission port 39 and opening the exhaust port 40. It is apparent that when the consumption system is closed as by closing all of the faucets the pressure in the tank 5 rises and shuts off the valve 37-39. This valve stays closed until the faucets or'other outlets are opened to reduce the pressure.

ln F ig. 2 I have illustrated diagrammatically a modification of the invention in `which the admission and exhaust to and from the cylinder'l is controlled by means of a cylinder and piston 56-57 which act as relay means for operating the valve 58 in the valve casing 59. This valve casing contains an admission port 60, and exhaust port 61 governed by the valve58. The valve casing 59 is secured to the cylinder 56 by means of Va pipe 62 which not only connects these parts together but serves as a supply pipe for air for operating the pump 1. he pipe 63 leading to the cylinder 56 is in this case adapted to be connected to the valve 11 instead of the pipe 10. The pipe 64 which supplies air for operating the pump is adapted to be connected to the tank 2 as fc instance by connecting with the pipe 13. But when the master valve 11 operates to admit air tio/the pipe 63 the piston 57 is driven downward opening thef admission port 66 and closing the exhaustport 61 oli the 'controlling valve 58. This admits compressed air from the tank 2 to the pump 1 by way oi the short pipe driving the water out at the discharge pipe 3 and raising the pressure in the tank 5 whereby the valve 11 is operated. c

The movable valve 58 is connected by means of a rod 66 to the piston 57 so!! that the movement of the piston 57 is transmitted to the valve 58.
