AIR bPERATED GASOLINE, WATER, OR OTHER FLUID PUIP Filed Oct. 5,1938
Patented Dec. 26, 1939 UNITED STATES ATENT OFFICE AIR OPERATED GASOLINE, WATER, OR OTHER FLUID PUMP 2 Claims.
This invention relates to certain new and useful improvements in air operated gasoline, water or other fluid pump.
The primary object of the invention is to provide an air operated gasoline, water or other fluid pump with an improved construction of valve mechanism that is float-controlled in its operation for placing'the compressed air line in operative relation to the gasoline, water or other fluid to be pumped.
A further object of the invention is to provide pump mechanism of the foregoing character embodying a tank or cylinder adapted to be lowered and immersed in a column or tank of fluid with valve mechanism at the upper end of the cylinder controlling the exhaust of air from the cylinder during the filling of the latter with fluid and also controlling the operation of a valve device to permit the flow of air under pressure into the cylinder to force fluid therefrom to the point of use or consumption.
"With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.
In the drawing:
Figure 1 is a vertical longitudinal sectional 30 view of the pump mechanism showing the valve mechanism at the head of and within a cylinder and the float operated devices for operating the valve;
Figure 2 is an enlarged vertical sectional view of the cylinder head upon the lower side of which the valve devices are supported; and
Figure 3 is a bottom plan View of the cylinder head.
Referring more in detail to the accompanying drawing, the compressed air operated pump comprises an elongated cylinder 5 of the desired capacity that has water-tight secured to the lower end thereof, in any suitable manner, a base block 6 while a head I is similarly secured to the up- 45 per end of the cylinder 5, the lower end of the head i being annularly reduced as shown at 8 for telescopic reception in the upper end of the cylinder.
Ihe base block 6 of the pump cylinder has a pair of valve openings 9 therein with which freely supported and movable upwardly opening valves 10 within the cylinder 5 are associated,
each valve 10 carrying a depending stem ll freely slidable in a bore in the base block 6 with a 5 cross pin [2 at the lower end of the valve stem H movable into engagement with the bottom face of the base block 6 for limiting upwardly opening movement of the valve.
As shown more clearly in Figure 2, the cylinder head 7 has a cross bore 63 therein that has its ends adjacent opposite sides of the head I directed downwardly as at Ba and preferably internally threaded at its endsthat open through the bottom wall of the head forthe threaded reception of the upper ends of a pair of diametrically opposite longitudinally extending pipes l4 within the cylinder 5, the lower end of each pipe It being anchored in position relative to the base block 6 by the locking ring [5 as shown in Figure 1. Each pipe M within the cylinder 5 and at a point adjacent thelower end thereof in proximity of the base block 6 is provided with a lateral inlet port I6 whereby water or other fluid in the cylinder 5 is forced upwardly through the pipes M into the cross bore l3 in the head I of the cylinder. A valve seat I! is provided at the upper side of the cross bore [3 centrally of the head i and with which a downwardly closing ball valve I8 is associated, the valve seat I! and ball valve l8 being surrounded by an-upstanding internally threaded pipe fitting l9 for the attachment of a pipe or other conduit for the flow of water or other fluid to the point of use.
As shown more clearly in Figures 1 and 3, the cylinder head 1 has. diametrically opposite openings 20 and 21 therein respectively at opposite sides of the cross bore 13, the openings 20 and 2| extending through the upper side of the head for the threaded reception of pipes 22 and 23. The lower end of the opening 20 communicates with a cross bore 24 adjacent the bottom of the head I with the cross bore in proximity of the center of the head I terminating in a port 25 opening at the bottom of the cylinder head, the port 25, cross bore 24, opening 20 and pipe 22 constituting an exhaust passage for air from the cylinder 5. A cross bore 26 extends from the lower end of the opening 2! to a point adjacent the center of the bottom of the cylinder head 1 and terminates in a downwardly opening port 21, the port 2?, cross bore 26, opening 2| and pipe 23 constituting a conduit for the supply of air under .pressure to the pump cylinder 5.
Valve mechanism and float operated devices therefor are arranged in the cylinder 5 for controlling the exhaust of air from the cylinder through the exhaust pipe 22 and the admission of compressed air to the cylinder through the compressed air inlet pipe 23, the valve mechanism and float with their associated devices including a block 28 secured to the bottom face of the cylinder head i by means of screw bolts passing therethrough and engaged in the openings 29 in the underside of the cylinder head IT, such openings being illustrated in Figure 3. As shown in Figure l, the block 28 has an angular passage 30 therein forming communication between the interior of the cylinder 5 and the port 25 in the head I, the passage 38 having a valve seat 3| therein that is adapted to be engaged by a slide valve 32 operating in a manner to be presently described. The block 28 has a cross bore 28a therein with a valve 33 slidable in the bore and tensioned in its closing direction by means of the coil springs 34 engaged with one end of the valve 33 while the other end of the spring is engaged by a screw plug 35 set into the outer end of the bore 2811 at one side of the block 28. The inner end of the bore 28a communicates with a valve opening 36 with the valve opening communicating with a downwardly opening central chamber 31 in the block 28, the polygonal valve stem 38 extending through the valve opening 35. A lateral port 39 in the block 28 forms communication between the Valve opening 36,0hamber 3i and port 21 in the cylinder head 1 whereby air under pressure may flow through the pipe 23 and enter the cylinder 5.
A bracket arm 40 depends from the block 28 and pivotally supports a lever 4| adjacent its upper end as at 42, the upper end of the lever 4| carrying an arm 43 extending upwardly into the chamber 31 for engagement with the polygonal valve stem 38, which, when the lever 4| is-moved on its pivot 42, acts to unseat the valve 33. A forked arm 44 projecting laterally of the lever 4| above the pivot 42 supports the sliding valve 32 for forcibly moving the same into engagement with its seat 3 i the valve 32 gravitationally opening. The side of the lever 4| opposite the forked arm :24 carries a laterally directed arm 45 engageable with the under side of the block 28 for limiting pivotal movement of the lever 4| in one direction.
The lever 4! is tensioned by devices that act to hold the same at its limit of pivotal movement with the arm 45 carried thereby engaged with the under side of the block 28 or the forked arm 44 engaged with the valve 32 to hold the same onto its seat 3|. The tension devices include a lever 46 pivoted intermediate its ends as at 4'! onto the lower end of the bracket arm 48, the lever 48 carrying a depending arm 48 intermediate its ends, a coil spring 49 being interposed between the lower end of the lever 4| and the lower .end of the arm 18 and of a length and force to hold the lever 4| at its limit of pivotal movement. A float 5|) carries an upwardly extending arm 5| at one side thereof with the upper end of the arm pivotally attached as at 52 to one end of the lever 48 while a weight 53 carrying an upwardly extending arm 54 has the upper end of said arm pivotally attached as at 55 to the other end of the lever 45. Rods 56 depending from the float 5|] and weight 53 are guided in openings in a bridge-piece 5T suitably supported adjacent the lower end of the cylinder 5. A pair of adjustable abutments 58 are respectively carried by the lever 46 at opposite sides of the lever 4| and upon pivotal movement of said lever 46 are adapted to be moved into engagement with the lever 4| for moving the latter on its pivot 42 for the operation of the valves 32 and 33.
The pump cylinder 5 is adapted to be lowered into a tank or well and submerged in the fluid therein, the fluid entering the cylinder 5 through the valve openings 9 and the upward movement of the fluid into the cylinder 5 forces the air in the cylinder through the valve opening 3| and exhaust pipe 22. During the rise of fluid in the cylinder 5, the float rises, being balanced by the weight 53 for the operation of the lever 46, one of the stops 58 carried by said lever 46 being engaged with the lever 4| when the cylinder 5 is substantially filled with fluid for moving said lever 4| against the tension of the spring 49 to cause the upwardly extending arm 43 carried by the lever 4| to shift the valve stem 38 and unseat the valve 33, such movement of the lever 4| closing the valve 32 on its seat 3| and allowing compressed air from the pipe 23 to enter the upper end of the cylinder 5 and force the fluid therein upwardly into the pipes M by the inlet openings or ports l6 adjacent the lower ends of said pipes to enter the cross bore E3 in the cylinder head 1 and pass outwardly thereof through the valve opening H to the point of consumption. As the fluid is forced from the cylinder 5, the float 50 lowers therein for reversely pivoting the lever 56 and causing the other abutment 5S thereon to reversely pivot the lever 4| for moving the valve 33 to close the valve opening 36 and opening the air exhaust valve 3|, so that fluid which again enters the cylinder 5 is unrestricted in its flow thereinto by the exhausting of the air in the upper end of the cylinder through the exhaust pipe 22.
While there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
I claim:
1. In a compressed air operated pump of the character described, a cylinder having valved fluid inlets at its lower end, an air exhaust and compressed air inlet at the upper end of the cylinder, separate valves for the air exhaust and compressed air inlet, a tensioned lever having a pair of arms respectively engaged with the valves for sequential operation thereof and normally held at its limits of pivotal movements in opposite directions, fluid delivery means associated with the cylinder and float operated means for the operation of the tensioned lever, the air ex- N haust control valve being supported on its lever arm and positively closed on its seat by upward movement of said arm, said exhaust valve gravitationally opening upon lowering movement of its supporting arm, the compressed air inlet valve being spring pressed to closed position on its seat, and the float operated means including a lever having adjustable abutments thereon movable into engagement with the tensioned lever at a point adjacent the limits of movements of said float operated lever for causing the tensioned lever to move with snap action for the operation of the exhaust and inlet valves.
