Application 111ed` Hay '3,'

This` invention* relates 'to improvements in Fig. 2 is a part section taken along the line 2-2 o f Fig. 1.

Fig. 3is a side elevation of the pumping apparatus. j I I Referring tothe drawings numeral 20 designates the. container' or crankcase provided withv an open end 21 adapted to beclosed byl means of a cover plate22 held in position by studs 23. Container 2() has a flange 24 25 whichis adapted to fit on a flange 25 provided on the tank 26. Flanges'24 and 25 are held together bymeans of studs 27. The tank 26 has a pipe 28 which forms communication between the inside of the :au container 20 and tank 26.' Another pipe 29 leading from the tankv 26 'connects withthe various pi es not shown through which 4Huid is delivere from the tank 26 to various outlets, not shown.

A lug 30 formed on the container 2O has a passage lcommunicating with the inside of said container, said passage being screw threaded to receive a coupling 32 to which is secured the pressure switch member 33.

`4o This pressure switch member 33 is controlled by pressure within the container 20 and is adapted, in turn, to control the operation of the electric motor 34 which is mounted on the upper surface 35 of container 20.

The motor 34 includes a drive shaft 36, to

the outer end of which is secured a driving ulle 37 shown-in the present drawings to e o the V-type. A corresponding V-type,

pulley 38, of greater .diameter however, is

to secured to the drive shaft 39 in any suitable manner. A V-type belt 40 connects the driving pulley 37 with the driven pulley'38.

Within the container 20cthere is provided `a tubular portion 45 preferably -formed inricate lthe moving elements ofl tween the upper edge of the seat 62 formed about 191m.` seria; no. losaoe.

ytegral-`v with said container. This tubular portion is open at both'ends and hasan aperture 46 communicating with the inside of the container. At the edge of this aperture nearest'the -inner open end of thetubular portion there is providedan u wardl extending partition 47 which terminates ow' the 'ceiling20 of the container 20. This partition forms

chambers

48 and 49 inside` thejsaidfcontainer, said, chambers being in communication with each other by means of the vpassageway 50 formed bythe space bepartition 47 and the ceiling 20'* of the container.

The outer end of the tubular portion 45 is providedwith screw threadson its interior 7 surface for receivin the valve cage51. This valve vcage is provi ed with assag'es 523ml 53 formed on opposite sides o a central lug 54- Passage 53 communicates with a passage 55 formed'in the tubular portion 45, said passage having a plug 56 provided therein. Passage 52 communicates with the intakeV port 57, formed by housin extension 58 secured to or formed integra with the end wall of the container 20. Pipe 59 is connected" .to the intake port 57, said. ipe 59 lea to any desired source of iiui to be pum said source not being shown in the presenty drawings. v

The central lug 54 has a screw-threaded recess which receives the pin 60, said in'-` supporting a collar 61 at its free end. e vaive 'ca-ge is provided with an annular valve passages 52 and 53. The end of the central lug 54 is flush with the, annular valve seat 62 and forms thew 'l yinner section of the valve seat. "En aging with this valve seat is a disc valve 63 oosely carried by the pin and `held against its seat by means of a spring interposed be tween the collar 61 and the valve.

A vcylinder 65 is provided in the tubular portion 45, the one end of the cylinder-lyn in spaced relation with the valve cage 5% while the other end of thefsaid cylinder ex- 1N tends intov the container 20 as shown in Fig. t 1.. The cy1inder65 is provided with a plu- .rality of apertures 66 adjacent theinner of the aperture 46 of tubular portion 45.

' The cylinder 65 includes a iston' 70 which comprises a cross head mem r 71 and va. piston .head comprising an assembly of various elements to be described. '111e .surrounds the cylindrical'portion 72 of said cross head, said bearing bushing being interposed between the spaced shoulder portions 73 and 74. This bearing bushing slidably supports the cross head 1n the cylinder 65. In umps used for delivering water it is pre erable to use leather for the bearing bushing 4rinasmuch as water will tend to lubricate the same and keep it in good condition.

Extending-forwardly toward the valve cage 51 there is kanother cylindrical portion 76, of lesser diameter than the portion 72, secured to, or as shown in the drawings, formed integral with the said larger cylindrical cross head portion 72. This smaller cylindrical portion 76 is closed at its forward end by means of wall 77. Extending forwardly from the portion 76 and formed integral therewith is a spider portion including oppositely disposed arms 78, the outer edges of which are spaced from the cylinder 65. These arms 78 support a ring 79 of substantially lesser diameter than the cylinder 652 said ring being screwthreaded on its interiorsurface for receiving a hollow sleeve A80. Hollow sleeve 80 has an outwardly extending iange 81 at its forward end by means of which the sleeve is adapted to act as a clamping element for v'the leather cup washers 82 and 83 which 'form the bearing elements of the piston head.' The washer 83 is clamped between the ring 79 and a spacer ring 84 which surrounds the sleeve 80 while the cup washer 82 is-clamped between'the spacer ring 84 and the ange 81 of the sleeve 80. vThus it may be seen that the piston head comprises the hanged sleeve 80, cup washers 82 and 83 with their interposed spacer ring 84 and the ring 79 which is secured to the cross head 71 by means of the spider arms 78.

The edge o f the inner end of sleeve 81 lies adjacent the spider arm 78 and forms a seat for the valve 86 which is loosely carried on al vstud 87 carrying a central guide member 88 rovided in the sleeve 80. The valve. 86 is eld against its seatby means of a spring interposed between the valve seat and the end wall 77 of the cross head 71, said valve being kept in alignment with its seat by means of the guide member 88 which is in the form of a spider to permit fluid to pass through the sleeve.

Due to the cross head portion 76 being of lesser -diameter than the interior of cylinder 65 a space or chamber 89 is provided in the cylinder. The cross head portion 72 and the piston head are so spaced that in any position of the piston duringy its stroke the apertures 66 of the cylinder 65 will be in communication with chamber 89.

A wrist pin 90 is carried in the cross head portion 72. The one end of the connecting rod 91 is connected to said `wrist pin. 90. The opposite `end of the connecting rod 91 has a bearing ring or strap 92 which fits abouta fibrous bearing bushing 93, preferably of leather, which is carried by the ecf centric 94 between spaced shoulders in a similar manner as the bearing bushing on the cross head. Eccentric .94,is mounted on the end ofthe drive shaft '39 that extends through container 20.

Referring to Fig. 2, the method bf supporting thedrive shaft 3 9 is clearly. illus# trated. A journal box 95 is provided having a iiange 96 apertured to receive studs 97 by means' of which the journal box is secured to the one side of the container or crankcase 20. The journal box- 95 carries bearing bushings 98 in which is .journaled the shaft 39. The bushings 98 are split and thereby permit a ring 99 t float on the drive shaft 39f'between said bearings, said ring being of sufiicient diameter so that its lower portion will dip into'the lubricant 100 provided in a lubricant pocket 101formed integral v with the journal box 95. The'hub of the pulley 38 has an oil groove 102 which substantially prevents any oil from finding its way t'o the aperture in the journal box through which the hub of the pulley 88l ex#l tends. u

The surface of the flange 96 adjacent the side wall of the cranlcase 20 is provided with an annular protuberance 103. A dia.- phragm 104 surroundsV the shaft 39 and is interposed between the protuberance 108 and the surface of the crankcase 20, said diaphragm being clamped tightly therebetween when the studs 97 are drawn up to clamp journal box 95 against-'the crankcase. A sealing ring 105 surrounding shaft 39 is secured to the diaphragm 104 by means of soldering or welding, said sealing ring being recessed to receive a bearing ring 106 made u of any suitable lubricant containing materia The sealing ring 105 is positioned in-'the aperture formed in the side of the crankcase 20 and which is closed by the diaphragm 104.

The shaft 95 has a iiange 107 whose inner surface engaffes with F'the bearing ring 106. f'

The end of t e shaft 95 which lies adjacent the inner Wall of the crankcase or container 20 is engaged by the-convex surface of a washer 108 provided in a recessed nut 109 screw-threaded in the passage of a lug perf tion 110 formed on the one side of the con;

tainer or crankcase 20. A springy 111 is interposed between the end 112 ofthe recessed nut 109l and the washer '108, lsaid spring tending-to exert a pressure upon the washer whereby the shaft 39 will be :forced to the right as `regards Fig. 2. Pressure of the s ring 111 against the shaft39 will force the' ange 107 against the bearing ringv 106. A. 6 seal will thus 'be provided which will preventlubricant 100 from lpassing alongthe shaft-,39 and entering intothe container 20 and also the fluid in container 20 will be prevented fromentering the lubricant pocket l 101. l

. l When the motor 34'is o erating, the pul-` ley 38 will-be rotated thereby causing operation of the eccentric 94. Operation of the eccentric 94 will reciprocate the piston in l the cylinder 65. J y

Ony the stroke of the iston to the right as regards Fig. 1 fluid wi l be drawn through the pipe 59 into passage 52, said luld then opening the valve 63 against the eilect of its spring to hold it closed, entering the cylinder 65 on the side of the piston opposite the cross head 71. This movement of the piston will cause the cross head 71 to exert a pressure upon the fluid in the container 20 thereby Vtending to compress thevair'in said container and thus build up a pressure in the container to force fluid from tank 26 when an outlet is opened.

On the reverse stroke of the piston or to 30 the left as regards Fig. 1 vthe piston will exert a pressure on the fluid in the intake chamber of the cylinder or more specifically the chamber between thevalves 63 and 86, vthus closing the valve 63 and opening the '.35 valve 86. The fluid will now pass from the chamber between said valves 63 and 86, past the valve 86 into the space 89. The cubical contents of space 89 when the piston is at the extreme right position being substantially 40 less than the cubical contents of the space between the valves 63'and 86 more lluid will be forced past the valve 86 than said space 89 may contain, thus a greater portion of this iluid will be forced through the aperture 66 of the cylinder 65 into 'the chamber 48 of the container 20. Continued operation of the pump will build upa pressure in the container 20 which, when it has reached a proper value will operate the pressure switch 50 element 33to disconnect the'motor 34 from the source of current thus causing it to becomev inoperative. pressure 1n the container 20' reaches a proper low level, to be determinedv` the pressure switch element 33 will again be operated to connect the motor 34 and institute the pumping operation. o i As has been mentioned before the working portions of the pump including,r the cup washers82 and 83 of the piston` the bearing bushing 75 of the cross head and the bearing bushing. 93 of the eccentric and connecting -rod areof such a material preferably leather for water pumps that the fluid within the 5 container or crankcase 2O will keep lthe same 4maintain a fluid level in 'municating with the intake port 57 for purport 57, thence through However, as soon'as the well lubricated, thereby eliminating the necessity of providing separate lubricating systems for each of these elements.

The provision of the artition 47 will tlie chamber 48 of.

the container 20 regardless of the exhaustion vof fluid in both the container chamber 49 and tank 26 thereb 'maintaining a priming medium for the va ves r86 and 63. l

A valve 120 is provided in connection with the chamber between the valves 63 and 86 whereby air may be supplied tothe container 2Q whenthe same becomes water logged. A cap 121 is provided in the passageway ,comv poses of priming said intake port when it becomes necessary.
