This invention aims to provide a simple form of pump, which is efiicient in operation,
novel means being provided for returning to,
With :the above and other objects in View,
which will appear as the description pro- 1.5 ceeds, the invention resides in the combination and arrangement of parts and in the ,de-
tails of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodi- 20 ment of the invention herein disclosed, Within the scope of what is claimed, without departing from thespirit of the invention.-
Inthe accompanying drawings Figure 1 shows in section, a device constructed accordance with the invention;
Figure 2 is a section taken longitudinally of the pump, the cutting plane in Figure 2 being remote from the cutting plane in Figurel;
Figure 3 is a transverse section taken through the main part of the pump;
Figure 4 is a, transverse section taken through one ofthe valve housings.
In carrying out the invention, there is provided a casing, denoted generally by the numeral 1. The casing l is a composite structure including a central portion or body 2 and valve casings 3 and 4 secured at oto opposite ends of the body 2. A lid 6 is secured on the body .2. The casing 1 maybe supported on a pedestal 7 connected to the body 2. There is a chamber 8 in the valve housing 3, and the valve housing 4 issupplied with a chamber 9. A lower passage 10 is formed in the body 1 and in the valve housings 3 and 4. The lower passage 10 has an inlet 11. An upper passage 12 is formed in the valve housings 3 and 4 and in the body 2. The lower passage 10 is located in the longitudinal center of the casing 1.
The invention aims to improve generallyv 1930. Serial No. 458,959.
The central portion'of the'upiper passage. 12 is oifset to one side of the median tough tudinal plane of the casing 1, as be understood readily when Figures 2 .and 3. are compared. Intermediate its ends, the upper passage 12. is supplied with an outlet 14 located in the body 2. v
The housing 3' carries: a .spr-ingmpe-rated valve 1.5v which closes toward the passage 10-, and governs the backflow from the chamber 8 into thespassage 1.0.. The valve housing carries .a valve 16 which closes toward the chamber .8 and governs the backfiow from the upper passage 12 into the chamber 8. "The valve housing 4 carries .a spring-operated valve 17 which. closes toward the lower passage l0 and gouernsithe back flow from the,
Removable plugslt) may be mounted in the upper ends of the valve housings ;3 and 4 to give access to the chambers 8 and 9,.
The casing l hasa central compartment 20 1 located in the body 2 and. extended upwardly into the lid :6. The compartment 20 is contractedin Width, asshown in Figure .3, in its middle portion, the compartment extending into the upper part of the body 2 and being of considerable width within the lid .6. Across the compartment '2 extends a flexible diaphragm 21 which may be made-of a ruleber compound or any other suitable material; The fieXiblediaph-ragm21 rests on .a shoulder 22 in thebody 2 and is'held on the shoulder 22 loya'removable frame23secuned to the shoulder and locatedabove the .diaphragm21.
The casing 1 has aside chamber 24 located in the central body 220i the pump. Adri-ve shaft 25 is journaled for rotation theibodry 2 and extends across the chamber 24'. The shafit 25' may :be rotated in anyvdesired way, for instance, by meansof an external wheel 26,. An eccentric 2'1 is secured to the drive shaft-25 and islocated in thesidechamher 24;. Around;1the-eccentric-27 extends: a strap :28 pivoted to a depending'arm 29-ononeaendiof a shaft- .39- ihaving; depending; fingers .31
' mounted to swing on .pin shafts 32 carried by bearings 33 located in the body 2, the shaft 30 being disposed in the extreme upper part of the chamber 20. Intermediate its ends, the shaft 30 is supplied with a depending boss 34 defining a shoulder 35 from which projects a threaded stem36 carrying an arm '37. p
The stem 36 extends through thefiexible diaphragm 21. against the shoulder 35 and is held in abutment with the shoulder by a nut 38 pivoted on the stem 36. The lower end of the arm 37.
with the passage 10. The upper end of the tube 43 is located immediately under the flexible diaphragm 21 and ordinarilyis closed by the said diaphragm. Among other functions, the diaphragm 21 takes the place of stuffing boxes and glands usually found in an analogous place in similar force pumps. 3
In practical operation, the shaft 25 is rotated by the wheel26 and the eccentric 2.
cooperating with the strap 28, imparts swinging movement to the shaft 30 by way of the arm 29. When the shaft30 is rocked, the arm 37 cooperates withthe pitman 39 and the rod 40'to move the pistons 41 in opposite directions The water enters the lowerpassage 10 by way of the inlet 11 and is'suck'ed past the valves 15 and 17 by the action ofthe pistons 41. When the direction of movementof the pistons41 is reversed, the valves 15and 17 close, and the valves 16 and 18 open, the wa ter entering the upper passage 12, and leaving by the outlet 14, the pump being a double acting pump in operation. 1
The purpose of the flexible diaphragm 21 is to prevent the water from working into the side-chamber 24,and it supplants stuffing boxes and glands, as hereinbefore mentioned.
is not inroperation, prevents back pressure in The diaphragm 21, moreover, when the pump the inlet from passing the piston and leaking away, as would be the case if glands or packings entered into theconstruction. The diaphragm also regulates the height of the water in the compartment 20 and keeps the pump primed at all-times: The diaphragm 21 can raise when. enough water has leaked past the pistons 41 into the compartment 20, and when 7 diaphragm 21 raises, the upper end of the tube or duct 43 is uncovered, and the water is sucked. back into the lower passage 10 until the flexible diaphragm'21 closes down again on-the upper endof the tube or duct 43, due to the formation of a partial vacuum. 7 Having thus described the invention, wha
is claimed is.:
r 1. Apump comprising casing #0371;
The diaphragm 21 abuts.
inder carried thereby, the casing having a compartment communicating with one end of the cylinder, a piston slidable in the cylinder, a flexible diaphragm carried by the casing and extended across the compartment, an arm passing through the diaphragm and hermetically mounted therein, means in the compartment, on one side of the diaphragm, for connecting the arm to the piston, means in the compartment, on the opposite side of the diaphragm, for operating the arm, the
casing being provided with a duct for conducting away liquid which leaks past the piston into the compartment on the first-specified side of the diaphragm, the intake end of the duct being closed by the diaphragm in thenormal operation of the pump,-the dia phragm yielding under piston pressure,'when the compartment is full of liquid on the firstspecified side of the diaphragrmto space the diaphragm from the intake end of the duct and permit liquid which has leaked past the piston to flow away through the duct.
2. A pump comprising a body provided intermediate its ends with a vertical com partment, the body being provided upon one side with a vertical chamber spaced from T thecompartment, the body being supplied with inlet passage extended underneath the compartment, the body being provided arm located outwardl'y'of one finger and extended downwardly into the vertical chamber, means for mounting the fingers pivotally on the top of the body, means for connecting the first arm with the pistons, a shaft journaled in the body and extended across the vertical chamber, means housed in the vertical chamber for connectingthe second arm withthe shaft, and a lid on the body, the
lid covering the shaft and forming a closure for the vertical chamber. V.
