Application led May 1,

To all whom t may concern.' c

Be it known that I, FREDERICK A. WAG- NER, a citizen ofthe United States, residing at Rochester, in the county-of Monroe and State of New York, have invented certain new and useful Improvements in Pumps;

and I do hereby declare the following to be vtank and secured in lugs 9, projecting lata full, clear, andl exactrdescription ofthe same, reference being had to the accompany-` ing drawings, forming-a part of this speciiication, and to theV reference numerals marked thereon. v t

`My present invention relates -to pumping apparatus and more particularly to equipment designed for household use to provide a constant supply of running water from an individual tankand an automatically operated power unit connected therewith and the inventionhas for its object to provide an improved apparatus of this character that will be compactly arranged andeasily Vshipped and set up or dismounted by relatively unskilled persons. The improvements are further directed toward providing a positively acting mechanism so protected and arranged as'to giveV long service withv To these and other very little attention. Vends the invention resides 1n certain 1mprovements and combinations of parts' all as'will be hereinafter more fully described,

the novel features being pointed out in the claims at the end of the specification.-

In the drawings: 1 M I Figure 1 is a front view of a pumping unit constructed in accordance with and il# lustrating one embodiment of my invention;

Figure 2 is a top view thereof; r

Figure 3 is a detail sectional view ofthe tank connection taken on theline 3--3 of Figure 1;

Figure 4 is a vertical section, slightly enlarged, taken longitudinally through the pumping cylinder on the line 44 of Figure 2 and Figure 5 is an enlarged transverse section through the pumping cylinder and valves on the line 5-'5 of Figure 2.

Similar referencel numerals throughoutY the several views indicate the same parts.

Referring more particularly to the drawings 1 indicates thefusual type ofvertical pressure tank having an intake 2 and dis- 'Y 1923. Serial No. 635,958.

n points 'by front legs 6 and a rear leg 7 par- .alleling the tankiwhich insures its stability.

It is held securely to the tank at the top or in its'own plane by a strap 8 embracing the erally from the table, by nuts 10. A similar strapor band 11lower down has its ends rsecured by -nuts 12 in lugs 13 on the rear mostrleg 7 The unit is shipped completely assembled except for the attachment of the table to the tank and the necessary pipe connections hereinafter described. All'the pur-V chaser has to dois to make these pipe con- .nections and apply the straps 8 and 11 with the four nuts which is a simple'matter.

The table isk preferably substantially squarev as shown. Extending from side to side at the. front thereof is the `pump embodying a cylinder and valve case 14 and a crank case 15 folded together at 16. The pump cylinder 17 contains a piston 18 on a pistonrod 19 acting through a stuliing box 2Q located at the joint between the two cases.Vr Atthe' o-pposite vend of the piston rod isa cylindrical cross head 21 havinga suit-able guideway 22 in the extensionof the crank case to which cross head the crank 23 is connectedby a wrist pin 24. The crank, counterweighted at 25, has a bearing 26 on the crankv 27 of a crank shaft 28 extending transversely' through' the crank case 15.v

- ing it tothe shaft 31.

The pump is'double acting, one end communicating with a water chamber 35 and the other with a water chamber 36 in vthe case 14. These chambers are 'supplied with water from a common supply chamber 37 arranged at `the lower front portion of the case 14 and into which leads the supply; pipe 38 connected to the source of water supply. Communication from the supply chamber 37 to the respective chambers 35 and 36 is had through intake valves 39 one Vof which is shown in Figure 5. Each valve consists of a cage 40 forming the seat and having a central lug- 41 supporting a post 42 in the present form of a shouldered screw having a head 43. The valve 3S) is a disc valve movable on the post and closed by a spring 44 surrounding the latter. Upward movement of the valve against the tension of the spring is limited by the head 43. The spring at its upper end bears against a plug 45 which is removable and of such a size as to then give access to the entire valve and permit the removal of the cage 40 if required. This is of great convenience in cleaning and adjusting the valves.

Opposite each intake valve 39 and at an elevation above the same to the rear of and above the'cylinder 17 is a discharge valve 46 constructed and operating the same as the intake valves 39 and similarly accessible through the removal of plugs 47. rllhey lead from the respective chambers 35 and 3G to a discharge chamber 48 from which runs a pipe line indica-ted generally at 49 delivering into the tank 1 at 2. The operation of the pump and valves will be obvious to one skilled in the art-when the piston '18 moves to the left in Figure 4 the intake valve 89 israised in chamber 36 and the discharge valve opens in chamber 35 while on the reverse stroke there is a similar result with respect to the other two valves. lt is to-be noted in this connection that the discharge valves 46 are at the tops of the L- shaped chambers 35 and 36 while the intake valves 39 are at the low level of these chambers with the result that if air enters with the water it will collect in the vicinity of the discharge valve and easily escape therethrough and not interfere with the operation of the intake valve.

The cylinder 17 and piston 1S are also made accessible through an aligned plug 50 of the nature of the plugs 45 and 47 for the valves and this plug is provided with a petcock 51 leading into the chamber 36. Sometimesv the air becomes so depleted in the tank 1 that it is desirable to pump in more air along with the water without emptying the tank and it is for this purpose that the petcock is provided.

The usual form of air chest 52 is provided on the discharge chamber 48 to maintain a uniform pressure in the line 49. There is also located in said line a suitable pressure valve 53 which may be adjusted to yield at `a given overload and discharge the water at 54 if for any reason the pump continues after the tank has been illed.

In the usual operation of the system and as before stated, the water enters the tank at 2 and discharges at 3 through the service pipe 55 provided with a suitable pressure gage 56. Such water is stored for a time within the tank and it is sometimes desired to obtain a direct supply of freshly pumpet water` as for instance when the water is drawn from a' well and it is desired to have cold water for drinking purposes. For this purpose I provide a fresh water lme 5.7 leading from the line 49 which latter is provided at the coupling with a suitable three-way valve the stem of which is indicated at 5S. Through the operation of this valve the water delivered by the pump instead of going to the tank can be diverted through the line 57. l

The intake or supply pipe 38 is provided with a priming chest 59 closed at the top by a plug 60. Also, by removing this plug air may be pumped into the tank for brief intervals which is necessary at times in order to maintain in the tank a sufficient body of air to maintain pressure.

The motor 33 is controlled by a suitable pressure switch so that it is automatically called into use when the pressure in the supply ine 49 falls below a predetermined point. This switch is located in the case 61 extending from a case 62 in which the dia phragm is housed. The circuit wires to the motor are indicated at 63 and the pressure line to the diaphragm from the pump line 49 is indicated at 64 but as pressure switches of this nature are generally known and such device in its ,details forms no part of the present invention, its interior arrangements are not shown.

It will be seen from the foregoing that my apparatus is compact and easily set up. The motor, pump, valve case and in fact all of the devices arranged on the table 5 are simple in construction and so arranged as to be readily accessible at all times. YIt is to be noted that the direct drive from the motor 33 to the pump crank shaft does away with 4the belts usually employed in apparat-us of this kind and which are a common source of trouble particularly where, as is often the case, the apparatus is located inra cellar where the air is damp or foul.
