This invention relates to pumping apparatus, and moreparticularly to pumps of the suction type.

The object of construct a pumping apparatus which will be simple and reliable, and having the parts thereof so constructed and arrangedl that they may be easily removed' therefrom in assembled relation for repairs o r replacements.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing, where-in the preferred embodiment of one form of the present invention is clearly shown.

In the drawings: Fig. 1 is a. longitudinal sectional view of a pumping apparatus embodying the pres@ ent invention, the removable cylinder and valve unit being shown in elevation.

Fig. 2-is a fragmentary sectional view of the removable cylinder and valve unit on an enlarged scale.

Fig. 3 is a view in side elevation of the pumping apparatus. In the drawings, a pump frame 20 is provided with a supporting log 21 and tie member 22 forming a drip chamber 23` both preferably cast integrally therewith. Meniber 22 is provided with a flange 22a. A

power head frame 25, provided with a sup' porting leg26, serves as a support for the free end of tie member 22 and for gear housing 27 having flange 27, member 22 and housing 27 being'secured to the power head`r frame 25 by bolts 28 which pass through the flange 22a, member 25 and flange 27, and nuts 29 engaging the ends of said bolts. Memberk25 also provides a support 30 for vertically disposed `electrc motor 31. and also provides vertically alined bearings 32 and 33 within which motor shaft 34 is journalled. A worm 35 is provided on motor shaft 34 between bearings 32 and 33. Member 25 is provided with two horizontally eX- tending arms 36 in which adjacent the ends thereof bearings (not shown) areV provided and in which is journalled a shaft 37 loosely carrying a worm gear 38 which meshes with worm The worm 35 is back of the plane of crosshead guide 43. An eccentric 39 carried by worm gear 38, is engaged by an y eccentric strap 40 which merges into .a connecting rod 41. A cross head 42 attached to the present invention is to the connecting rod 41 by pin 41EL is adapted to be reciprocated within a cross head guide 43 which is supported by cone shaped wall-v 44 of member 25, said Wall 44 extending into the tie member 22. Pump pistonrod 45 is adapted to extend into guide 43 and be detachably connected with cross head 42 being provided with an annular shoulder 46 adjacent theend thereof which ts within a tapped recess 47 in cross head 42. A hollow plug 48 surrounds rod 45 and is received by the threaded recess 47, and bearing against shoulder 46, connects rod 45 with cross head 42. Cross head guide 43 has threaded connection with a plug 49 having a central opening 50 of suicient size to permit plug 48 to pass therethrough. Plug .49 is recessed to receive 'with compression/lita cup washer 51 for holding packing 52 around rod 45 in position. Cup washer 51 is ofsuch size asto pass through opening 77 in wall 75 of pump frame 2O and to permit nut 98 to be -slipped over it olf the end of rod 45. Y

The gear casing 27 and lower portion of power head frame 25 constitutes a' lubricant chamber, in which the worm gear 38 operate's, thereby carrying lubricant to the worm 35. Lubricant is supplied to the -bearing 32 by a small pipe 6() 'which has its lower end as viewed in Fig. 1, submerged in the lubricant and the upper end thereof leading to bearing 32. An air inlet valve 61 is provided in gear casing 27, and a small-restricted passage 62 is provided in the cross head guide 43 serving 'as a vent and small enough to offer such resistance as to prevent a substantial amount of oil escaping therethrough. It will be apparent that when the cross head 42 is reciprocated to the left, as viewed in Fig. 1, air will be drawn through inlet valve 61 into the gear casing 27 and upon the return stroke of cross head 42 to the right, as viewed in Fig. 1, this air will be compressed by the cross head 42, .thus creating pressure on the lubricant in the lubricant chamber and forcing some of the lubricant up through pipe to lubricate the' bearing 32. rlhe lubricant will then run down the motor shaft 34 and drip back int-o the lubricant chamber.

The pump frame 20 includes 'an inner wall which provides a cylindrical intake vchamber 71, and an outlet chamber 72 which partly surrounds the inlet chamber and eX- no4 I lianged tends adjacent the ends of the inlet chamber, the wall 70 being common to both the inlet and outlet chambers and provided with alined openings 70a and 70b in opposite end walls 70 and 70d respectively of the inlet chamber 71. Inlet chamber 71 is connected with inlet pipe 73 leading from a suitable source of supply such as a well, and outlet chamber 72 is connected with outlet pipe 74 leading to suitable service pipes or elsewhere. A dividing wall 75 is provided hetween the pump frame 20 and the tiey member 22, being recessed as at 76 and provided with the opening 77.

A removablecylinder and valve unit 80, which is positioned within theintake chamber 71, comprises a cylinder 81 which is at its opposite ends and is threaded as at 82 and 83 for engagement with valve head members 84 and 85 respectively. Wall 70 is recessed at 861or receiving a gasket 87 and providing a seat for valve head member 85. Member 85 is provided with a plugging portion 85% for `closing opening 70 in wall L*70L Valve head membery 85 is provided with communicating passages 88 and 89 leading from the intake chamber 71 to the interior of cylinder 81, while passage 90 connects the interior of cylinder 81 with the outlet chamber 72. Valve head member 85 is provided with a central threaded aperture 91 for receiving hollow plugs 92 and 93. Plug 92 provides asupport for valve 94 which controls communicationbetween the inlet chamberf71 and the l interior of cylinder 81, and plug 93 provides a support for valve 95 which controls communication between the interior of cylinder 81 and the outlet chamber 72. Plug 93 is provided with an externally threaded extention 96 which passes through opening ,77,in Wall 75 and receives a nut 98 which when drawn up on the extension 96 fits in the recess 76 and also tends to compress the gasket 87 between the valve body 85 and the recess or seat 86, making a. tight joint.

Valve head member 84 is provided with communicating passages 100 and 101 leading from the intake chamber 71 to the .interior of cylinder 81, while passage 102 leads from the interior of cylinder 81 to theoutlet chamber 72. Valve head member 84 is provided with a threaded central aperture 103 .1n alinement with aperture 91 for receiv- 1n lu 104 and 105., Openin s 70l1 70", 77gaiid g1S09 are all in alinemeng y Meinber 84 is provided with a plugging portion 84a for closing opening h in wall 70d. Plug 104 provides a. support for valve 106 which controls communication between the interior of cylinder 81 andthe inlet chamber`7' 1. Plug 105 provides a support for valve 107 which controls communication between the interior of cylinder 81 and the outlet chamber 72. Plug 105 receives another plug 108 ctime the water that may .the right, as viewed for a purpose to be. described later. A threaded aperture 109 in' alinement with aperture 77 in wall 75 is rovided in the end of pump frame 20 adJacent the valve head member 84, and receives a plug 110 which is provided with a series of openings 111. Then the plug 110 is tightened up, a. gasket 112 between theend of plug 110 and the valve head member 84 is compressed, thus making a tight joint. A, nut 113 engages the threaded portion of plug 110 and compresses a gasket 114 between the nut 113 and the outer surface of pump frame 20, thus making a tight joint.

The pump piston 45a comprises cup leathers 120 and 121 spaced apart by disc 122 andheld in assembledy relation by nut 123 which. engages threadedmember 124. Pump piston rod 45 has threaded connection'with member 124 and loosely passes through alined openings in plugs 92 and 93, the opposite end thereof being connected with the cross head 42 as heretofore described. Felt washers 125 and 126, spaced apart by a bushing 127 are received within the threaded extension 96 which forms a stuliing box, thereby providing suitable packing for the pump piston rod 45, and lbeing held in position by packing nut 128.

l/Vhen the motor 31 is operated, the worm 35 drives worm gear 38 which in turn drives the eccentric 39 and eccentric strap 40, thus reciprocating the connecting rod 41 and causing the cross head 42 in the cross head guide 43. ing motion is transmitted from the cross head 42 to the pump piston rod 45, thus reciprocating the pump piston 45l within the This reciprocatcylinder 81. As the pump piston is moved to the left, as viewed in Fig. 2, a vacuum will be created in cylinder 81, causing valve 94 to open, whereupon water will flow from the intake chamber 71, through passages 88 and 89 into the cylinder 81. At the same be in the cylinder 81 on the left side of the pump piston as viewed in Fig. 2, will be forced through passage 102, valve 107 into the discharge to be reciprocated` chamber 72 and out into the service line.

0n the return stroke of the pump piston to in Fig. 2, the valves 94 and 107 will be closed and valves 95 and 106 will be opened, thus forcing the water to the right of pump piston that was drawn in on the previous stroke of the pump pistonout through passage 90 and valve 95 into the discharge chamber 72 into the service pipes, and drawing water from/the inlet chamber 71 through passages 100 and 101 and valve 106 into the cylinder 81. On the next stroke to the left of the pump piston, this water just drawn in will be forced out into the discharge chamber 72 as described before. lt will thus be apparent that for each stroke of the pump piston there will be a discharge and an intake of water,- thus securing a double acting effect.

'From the foregoing description it will be noted .that the power head member 25 has a variety of functions. It providesa. support for the motor 31 and also vertically disposed bearings for the motor shaft 34, as well as providinr one of the supporting i legs 26. This member 25 also supports the cross head 42 and providesa bearing support for the shaft 37 which carries worm gear 38. vThe member 25 also provides a convenient support for tie member 22 and gear housing 27, the wall 44 of member 25 and the housing 27 also providing a suitable lubricant chamber in which the drivingmechanism is located.

The cylinder and valve unit 80 may be easily removedA from the pump frame in assembled relation. The cup washer 51 is irst pried loose from plug 49 by means of a screw driver or other suitable tool, then the plug 49 is loosened from the cross head guide 43 and slipped together with washerl 51 back on the rod 45. Plug 48 is then loosened from cross head 42 and together with the end of rod 45 is pulled away from the cross head 1 42. The'plug 49 may then be slipped of over the plug 48 and the end of rod through means ofopening 50 in plug 49. This will leave the plug 48 and cup washer 51 still remaining on the rod 45. The nut 98 may then be removed from the threaded exten-n sion 96 of plug 93 and slipped over the Washer 51, plug 48 and the end of pump piston rod 45. P ug 110 is then removed from pump frame 20 and plug 108 is removed from plug 105. Avsuitable pulling tool having a threaded end may then be inserted into plug 105 in place of plug 108 and the entire cylinder and valve unit 80, including the pump piston and piston rod 45 may be pulled out through the threadedopening 109 in pump frame 20, the washer 51 readily passing through opening 77 in wall 75. After the cylinder and valve unit has been removed from the pump frame, the same may then be repacked or repaired and again inserted into the pump frame 20. A

The driving connections between the motor.31 and the crosshead 42 are easily aclcessible for repairs or replacements. Removal of bolts 28 permits removal of the gear housing 27, and permits lifting the power head supporting member 25, motor 31, worm gear 38, eccentric 40, connecting ro'd 41, cross head 42 and cross head guide 43 as a unit away from,y the tie member 22, after the piston pump rod 45 has been disconnected from the cross head 42. Upon removal of the gear housing 27 from the power head frame 25, the shaft 37 may be removed endwise from, its bearings, thereby making it possible to remove the worm gear 38, eccentric 39, eccentric strap 40, connecting rod 41 and cross head 42 from the member 25 in a direction away from the'cylinder and valve unit 80, after the pump rod 45 has been disconnected from the cross head 42. It will be apparent that these parts may be removed independent of the worm 35, and also the worm 35 and motor shaft 34 may be removed independently of the worm gear 38 and the parts connected therewith .just described. While the form of mechanism herein shown and described constitutes a preferred embodiment of one form of the invention, it is to be understood that other forms might be adopted and various changes and alterations made in the shape, size, and proportion of the elements therein without departing from the spirit and scope of the invention.
