P. BALLETTO Nov. 20, 1951 ACID PUMP Filed OCT.. 28, 1950 E402: MEW' f' Troja/Y Patented Nov. 20, A1951 UNITEDas'rggrlazs1v PATENT oFFICE Paul Balletto, Douglaston, N. Y. Application October 28, 1950, Serial No. 192,676
1 Claim.
This invention relates to an acid pump.
It is an object of the present invention to provide an acid pump adapted to be extended through a top of a drum and into the contents thereof and to receive and accumulate portions of the contents to elevate the same to a level beyond the top of the drum in order that the same can be discharged, and wherein the casings of the pump are simply fitted together with the inner one offset within the outer casing so that the outer casing may serve as the elevating passage for the liquid and wherein a simple one-way trap valve arrangement is provided in the lower end of the outer casing that is lifted to receive the liquid charge, but lowered over the inlet opening on the down stroke of the plunger.
Other objects of the present invention are to provide an acid liquid pump adapted to be tted into the top of a drum to remove the contents thereof which is of simple construction, inexpensive to manufacture, has a minimum number of parts, compact, easy to assemble, formed of standard sleeve parts and etcient in operation.
For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. l is a vertical sectional View of a drum with the acid pump embodying the features of the present invention fitted in the top of the drum.
Fig. 2 is a vertical sectional view of the acid pump. Y
Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 2.
Fig. 4.- is a fragmentary perspective view of the trap valve assembly.
Referring to the figures, I represents an acid drum having liquid or acid contents II in the bottom of the same. With the drum being stood upright, as shown in Fig. l, its top can be opened by the removal of a plug, not shown, and pump I2 thrust through a screw fitting I3 and supported in a vertical position within the drum. The screw tting I3 has a ange I4 adapted to lie over the top face of the drum. This fitting I3 is tightly secured to an outer sleeve casing I5 of the pump I2 so that the pump will be lowered into the drum the same distance each time with its lower end elevated from the bottom of the drum.
A trap valve assembly is secured to the lower end of the outer casing and comprises a securing retainer cup I6 having a bottom inlet hole I1 for the liquid and an inner sleeve I8 having diametrically opposite holes I9 and 20 in the sides thereof for receiving respectively projections 2| and 2 22 of a trap valve plate 23 having a skirted mem- .ber 24 adapted to lie over and surround the hole I1 and to close it off upon the down stroke of plunger 25. The valve element 24 is secured to the plate 23 by a rivet 26. The openings I9 and 20 receive the projections 2l and 22 of the plate 23 and thereby guide the movement thereof.
The plunger 25 operates in a pipe sleeve 21 which is eccentrically arranged in the outer sleeve I5 to provide liquid passage 28 through which the liquid is elevated on the down stroke of the plunger 25. This pipe sleeve 21 may be secured to the inner wall of the sleeve I5 by welding or in any suitable manner and the upper ends are joined together and closed by a cap 29 through which plunger rod extends. The upper end of the plunger rod has a handle 32 which is grasped to operate the plunger 25. The upward movement of the rod 3| is limited by engagement of a spring 33 supported upon a sleeve 34 with cap 36 tted .in the upper end of the inner pipe sleeve 21 and over which the cap 29 extends. Steel wool 31 lies in the cap 36 to keep the rod 3| clean and free of dirt.
On the exterior of the sleeve I5 is a tting -39 having a hole 4I therein and a nipple projection 42 to which hose 43 can be attached. A valve element 44 is adjustable in the fitting 39. The hole 4I is aligned with a small hole 45 in the outer sleeve I5 and through these holes on the valve element 44 being manually turned to its open position, the liquid or acid is elevated from the drum :gid discharged on the down stroke of the plunger Any liquid that may pass the plunger 25 may be returned to the bottom of the drum through the hole 46 lying on the opposite side of the pump and below the connecting flange I3.
The plunger 25, when it is lifted, Will suck in a charge of the liquid as the trap valve assembly will be lifted. On the down stroke of the plunger, the trap valve will be lowered over the opening I1 and the contents which have been sucked in will be elevated upwardly through the space 28 provided by the eccentric arrangement of the inner and outer casing sleeves.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.
Having thus set forth and disclosed the nature of my invention, what is claimed is: y
A pump construction comprising inner and outer sleeves, said inner sleeve providing the pump 3 cylinder and connected to the side wall of the outer casing eccentrically removed from the center of the outer casing whereby to provide an elevating passage for the liquid, thereby providing a unitary single pipe for the entire pump construction, a plunger operable in the inner casing and a rod secured to the plunger extending upwardly through the outer ends of he easing, a cap surrounding the upper ends of the casing, the lower endl of the inner casing being elevated from the lower end of the outer casing, and a trap valve assembly secured in the lower end of the outer casing, a discharge fitting secured to the outer casing and having openings in communication with the vertical passage of the outer casing and said trap valve assembly comprising a cupshaped retaining member having a bottom open ing, a sleeve in the cup-shaped retaining member` having opposing guide slots in the opposite walls 4 thereof, a trap valve plate having projections operable in the slots and a trap valve element of skirted formation secured to the trap Valve plate and adapted to lie over the opening in the re- 6 taining cup.
