Be it known that we, JOHN HENRY VAILE and HAR-RY F, Bon, citizens of the United States, and residing at Dayton, in the' county of '-lIontgomery and State of Ohio, have invented a new and useful Improvement in Pumping Apparatus, of whiclithe follow-* ing` speciticationis ay full disclosure.

,-The invention relates to a water pump- -ing apparatus particularly adapted for use in connection with` domestic watersupply systems. v Y `i v In commercializing domestic, water supply systems it hasbeen ,experienced that laymen in making installations failto, recognize the importance of following definite instructions for setting up Athe apparatus accompanying each shipment, thus making faulty and improper connections to the. disadvantage o f the equipment.` Frequent source of trouble is due to faulty and improperly made connections Vin the suction line from the pump to the'source vof water supply, a leak in the suction'line will permit the priming water in the line to readily drain therefrom,l resulting in the pump working idly without lifting water.

An object of the invention thereforeis to unitarily'combine a pump and priming reservoirl for constantly maintaining a priming chargeof water within ,the pump to a definite water level height which may submerge the suction valve of the pump or flooding the parts controlled by said valve, to reduce the possibilities'of inaccurate and imperfect connection in making `ATinstalla tions, with a more completeI combining and assemblingof the various parts and devices at the place "of manufacture resulting in a reduction of the costof ,manufacture, and

Y issuinor a more eicient'working ofthe system wlie'n installed. l

Further objects andfeatures of the invention are more fully revealed in the following description of the accompanyingrdrawings forming. a part hereof, andy inthe drawings like characters of lreference denote corresponding parts throughout the several views, of which:

Referring to the casing havingUba-se webs?J with and extending drawings, l indicates a cast integrally from the lower portionV f of the casing to provide a support. therefor:

The casing vinteriorly is subdivided linto chambers vby parti tion walls providing a p ump inlet chamber 3,' front rear 'suctiQn' chambers 4 4 and a mainwater 'inlet g chamber 5, The inlet r chamber '5k is formed. bythe partition lwalls or vertical and hor'i.- 110 lz oiital websG-fT 'respectively and an oiset casing portion .p

rejecting fromv ene side and at one end of the casing 1. The offset casing portion 8 vertically is equal in height to the height of the casing 1 and at its rear side and at the base'of the chamber 5 is provided with a water inlet opening 9 tapped for connecting the pipe 10 of the suction line for the pump leading to a cistern, well or water supply source. An open end tube 11 connecting 'with the base` web 7 through an opening in the web, longitudinally extends vertically and 'centrally through and above the chamber 5.' The tube 11 as a conduit at its upper end communicates with the chamber 5 and at its lower end with the pump chamber 3, through a horizontal passage 12 formed by the casing 1 andweb 7. i

, The casing 1 and its oiiset portion 8 has a plane upper surface receiving the apertured division plate 13 with a packing 14 interposed, and upon the division plate a water and air chest or casing 15 is secured, with suitable packing 16 interposed. The casing 15 is of a contour and interiorly subdivided by a partition wall or web 15 to provide a pump discharge chamber 17, an air chamber 18 open to chamber 17 and at an elevation above the water vdischarge opening 19 in the casing, and an air and priming chamber 20 directly above and open 'to the chamber 5 in the casing 1 through the port 21 in the division plate and port 22 in the upper Jface wall oi the casing 1. The tube 11 as a water trap for the pumpextends upwardly through said ports 21 and 22 into the chamber 20 to a height slightly above the seats oi the discharge valves of the pump. The casing 15 above the chamber 2O is provided with an annular flange 23 to provide a cup or funnel leading into the chamber 2O through an opening 24 normally sealed by a screw plug 25. The funnel being of service in initially priming the pump.

Pump cletac'lsf-As heretofore asserted the pump in construction may follow any well known principles most suitable for the particular class of service, and preferably including the principles set forth and embraced in the subject matter of Letters Patent #1,166,224 to H. W. Kimes, assignor to The Valie-Kimes Company, dated Deceniber 28, 1915. Said patent discloses the suc tion chambers and discharge chamber of the pump connection by permanently open ports independent of the valve controlled port or ports connecting said chambers. i

The suction chambers 1 -4 of the pump have portions extending downward at opposite sides of the inlet chamber 3 from which they are separated by the partitions or webs 264-26. t A piston cylinder 27 is mounted in the partition 26 and has its ends open and connnunicating with the downwardly extended portions `of chambers 11-4- respectively. Mounted in this cylinder is piston 28having a piston rod 29 connected there-to. The piston rod 29 passes through a stuiing box in cylinder head plug 30.

The chambers 41 which are separated one from the other by a vertical partition 81 communicate with the inlet chamber 8, through ports 32,33 respectively in the valve decks 26, these ports being controlled by yielding valves 34;-85.

The division plate 13 is provided with two ports S56-37 connecting the discharge chamber with the respective chambers lr-4:

These ports are controlled by yielding valves 38-39 similar in construction to the valves 811-35.

The tube 11 provides a water column for holding back the water in both the suction and discharge chambers of the pump so as to establish water level in the discharge chamber of lthe pump high enough to submerge or partly'submerge the discharge valves, and y holds the water nor'- mally inthe pump against any counterl'lowv through the suction line leaving at all times a priming charge of water in the pumpcyl-I inder.

The pump in operation lifts the water from its source through a suction line connecting with the inlet to 'chamber 5, exterior of the tube 11, thence downwardly through tube 11 into passage 12 and chamber 8, from whence, depending uponthe direction of piston stroke,

nately into the suction chambers Lil- 4.
