CHARLES HAROLD SPOONER, 0F PRINCETON, MAINE.

PUMP.

Application filed March 6, 1822. Serial No. 541,387.

T 0 all whom it may concern:

Be it known that 1, CHARLES H. SrooNnP. a citizen of the United States residing at Princeton, in the county of Washington and State of Maine, have invented new and useful improvements in Pumps, of which the following is a specification.

This invention relates to liquid pumps and proposes the construction of a hand operated pump of the reciprocating plunger type which has for its principal object the provision of means whereby the discharge nozzle of the pump may be selectively structurally associated with the body of the pump so as to be conveniently manipulated by the operator of the plunger or removable from the pump body for operation at a distance therefrom.

Another object of the invention is the construction of a pump in which the valves are readily accessible for cleansing purposes or for repairs.

With the above and other objects in View, my invention consists in the improved pump illustrated in the accompanying drawings. described in the following specification, and particularly claimed, and in such variations and modifications thereof as will be obvious to those skilled in the art to which my invention relates.

In the drawings accompanying and forming a part of this specification, and wherein the preferred embodiment of my invention is illustrated:

Figure 1 is a view of a pump embodying my invention shown in elevation, partly in cross section.

I Figure 2 is a view inelevation taken at right angles to Figure 1.

Figure 3 is a detail view in cross section showing the pivotal mounting of the nozzle.

Figure 4 is a cross sectional view of the discharge nipple showing the discharge valve.

Figure 5 is a transverse section taken along the line 5 5 of Figure 4.

Referring in detail to the several figures the numeral 1 represents the cylindrical portion of a casing to which is attached, or made integral therewith, an offset portion 2. A partition wall 3 separates the space within said easing into two parts forming a plunger cylinder 4: and a discharge chamber 5. These chambers communicate adjacent their lower ends by means of a port 6.

The plunger chamber is closed at its upper end by the flanged plug 7, which may be of wood or any suitable material having an inwardly extending portion 8 of the same diameter as the plunger chamber and being secured tothe casing by means of the screws 8. The plug 7 is centrally apertured to permit the passage therethrough of the plunger rod 9.

The upper and lower ends 10 and 11 respectively of the plunger rod are slightly reduced in diameter forming shoulders 12 and 13 against which are seated the washers 1e and 15 respectively. washers form the stationary abutments for spiral springs 16 and 17. The spring 16 is confined between the abutment 14 and a collar 18 the latter being pinned to the plunger rod 9 by means of a pin 19. The lower spring 17 is held between the washer 15 and the plunger e7. The object of the springs is to cushion the thrust of the plunge rod at each end of the stroke by coming resiliently into contact with the upper and lower surfaces of the plug 7. The upper end of the plunger rod is provided with a transverse handle 20 which is secured in place by the screw 21 or by any other suitable means.

The plunger 4-7 is provided with the metallic expansion ring 22 and the follower 23 and is secured in place by the nut 24 which threadedly engages the lower end of the reduced portion 11 ofthe plunger rod 9.

The lower end of the casing 1 is externally screw threaded as shown at 2 3 to provide means for detachably securing thereto the strainer" 26 which is formed. with a screw threaded socket 27 for cooperation with the threaded lowerend of. the casing 1 and provided with a plurality of strainer apertures 29. The lower end. 30' of "the strainer is imperforate and affords a base of support on which the pump is rested when in operation.

The strainer is provided with a. partition 31 which is perforated at 32 to form an inlet opening for the plunger cylinder.

Said.

' provided with the hose connection 40.

threaded .at 38, as shown. in Figured, to which is secured the discharge nipple 39 A discharge flap valve 48 is pivotally secured by means of the pin 49 to' a projecting perforated lug 52 forming a part of the nipple 37 and housed within the hose nipple 3'9.-

clalm asnew and desire to secure by Letters The flap valve 4-8 is normally seated upon the end oi? the nipple 37. The flexible hose 41 is' clampably secured to" the hose connection 40 by means ofthe clip; a2 and leads to the discharge nozzle dill The Vent hole 50 extending through the wall of the casing. 1 near its upper end provides an air relief for that part of the plunger chamber which lies above the plunger and affords an exit for the discharge of any water which may have leaked past the plunger 47. I

The casing 1 is provided on its outer sur face with a threaded recess 44 shown in Figure 3 into which is secured theprojecting tubular support 45 upon which. is pivotally journalled' thenozzle d3 by means o-fa projecting bracket 4'6 made integral therewith and provided with a cylindrical bearing aperture 51 which rotatably cooperates with said tubular support. Thebracket 46 is slidably detachable from the tubular support 45 so as to permit the nozzle 43 to be carried to a point remote from the pump when occasion demands.

In operating the pump it is placed in a pail or other receptacle containing the liquid to be discharged, with the base, 30 resting upon the bottom of said receptacle. The nozzle 4L3 may be conveniently directed at various angles of elevation'by being turned upon its pivotal support by the person operating the plunger. By the provision of the detachable strainer 26 adjacent the inlet valve and the detachable hose nipple 39 adjacent the discharge valve, said valves may be conveniently reached for the purpose of cleansing or for repairs by removing said detachable fixtures; The location of the dis charge opening 36 at a point below the upper closed end of the discharge chamber 5 constitutes the upper portion of said chamber an air compression chamber steadying the stream issuing from the inlet and cushioning the impact of the working. stroke of the plunger. While the specification refers to water as the liquid medium upon whichthe pump operates it is to be understood that it will operate equally well with. any other incompressible fluid. In the case of corrosive substances such as acids or sea water the materials used in its construction must be selected with a view to the characterofthe substance which the pump is intended to handle.

It will be understood that various changes may be made in the form and relation of parts to suit different requirements of use, and that the invention, therefore, is not limited to the precise details of construction and arrangement shown.

Having described my invention what I Patent is 1. A pump including a plunger cylinder and a discharge chamber communicating therewith, said discharge chamber being provided with an outlet adjacent its upper end,

therewith, said discharge chamber being:- provided with an outlet, a bossexte'ndinglaterally from the plunger chamber, the axes of said bossand outlet lying. in parallel planes, a nozzle journalled onsaid boss, and I a flexible conduit connecting said nozzle and outlet.

I 3. A: pump including a plungercylind'e'r and a discharge chamber communicating therewith, said discharge chamber being pro vided with an outlet, a boss extending laterally from the plunger chamber, the axes of said boss and outlet lying in parallel planes, a nozzlejournalled on said boss and freely detachable therefrom and a flexible conduit connecting said nozzle and outlet.

4-. A pump including plunger cylinder and a discharge chamber communicating therewith, said discharge chamber being provided with an outlet, a boss extending laterally from the plunger'chamberin a direction opposite tosaid outlet, a nozzle journalled on said boss and a flexible condu tco-n-nectmg said nozzle and outlet.

5. A pump including a plungercylinder and a discharge chamber communicating therewith at its lower end,- Sl1-l d1scharge chamber being providedfwith an outlet adjacent its upper end, a boss extending laterally from theplungerchamber, the "axes of said'b'oss and outlet lying in parallel planes, a nozzle jo urnalied on said boss, and a lien ible conduit connecting said nozzle and outlet. 1
