DOUBLE-CYLINDER DOUBLE-ACTING PUMP.
Application filed March 31, 1927. Serial No. 179,503.
My invention relates to double acting, double cylinder, reciprocating piston pumps. Such pumps are well adapted for use in 'visible dispensing apparatus for gasoline, in pumping the gasoline from the underground storage tanl to the glass bowl at the top. Their compactnes's permits their being mounted in the housing ofsuch apparatus. @ne object ot my invention is to provide a highly concentrated, inexpensive pump of the continuous flow type the `operation of which will not be interfered with by .small particles of grit and sediment.
Another objcctot my invention is to provide an apparatus that can be used to pump liquid continuously by continuous rotation of the crank in either direction, at the option of the user. A left handed person can use it with the same facility as a righthanded person.
.Another object is to provide a pump that is easilyv assembled and will have all necessary accessibility for cleaning'the valves or for making other repairs.
Another object of this invention is to have all working parts protected from the weather by the casing and run in the liquid pumped, rendering otherprovision for lubrication unnecessary.
The particular embodiment of my invention selected for illustration, is a `gasoline pump shown in the accompanying drawings, in which Figure l, is a longitudinal section on the axis ot the crank shaft and on the line l-l ot 2 as thoughshown there in full,
Fig. 2, is a cross section on the line 2-2 otFigure 1,
lig. 3, is a cross section on the line `3--3 ot` Figure l,
Fig. 4t, is a cross section on the line 4-4 of Fig. 6, the body castings only being shown. y y
Fig. 5, is a cross section on the line 5 5 et 6. the body castings only being shown, y
Fig. 6, is an elevation of the pump on the side opposite the crank, and
7, is a perspective ot one of the two similar machined castings forming the pump body, looking toward the side which is joined to the other casting.
Referring now to the drawings, the pump body is made up ot two generally similar' castings A and B. Casting A carries a connection c for the suction pipe (not sho-wn) and a connection 0:1 for the discharge pipe (not shown), and has a plugged opening a2 thru which Water and sediment may be drained from the bottom of the body. lVithin the outer side of the casting A is formed a cylindrical. chamber i3 preferably lined with a thin brass tube at. The inner side oit' the casting A is generally fiat in shape having an encircling raised portion a5. It also has a central rib al which extends lengthwise centrallyof this flat portion and at its ends unites with the opposite sides of n the encircling raised portion o5. Raisedv portions a5 and a7 have their seating surfaces in the same plane and a cutout gasket g1 of the same general form as said seating surfaces a5 and o7 is seated upon them. Bosses as on the surface oit the outer side oi the casting A are tapped to receive cap screws (not shown), bywhich the pump is secured to the housing, (not shown) in which it is placed.
Generally co-axial with the cylinder a3 at the top oiE the casting A is' an opening ai 30 for purposes ot assembly, which opening is tapped and closed by a screw plug alo. The bottom cylinder head is formed of a casting a secured to the casting A with gasket g between` by cap screws al* or in any other convenient manner; and carries a guiding portion (i12 (1o-axial with tho cylinder and bored to receive a depending prolongation p ot the piston P. A screw plug 613 is usedk to close the bottom of the guide om, and may 90 be removed ttor drainage.
The piston P is of any suitable double acting type, and the connecting rod p1 has `a cap p2 secured in position by cap screws p3 in the usual manner.
On the inner side of the cast-ing A are two longitudinal depressions @15, @16, one on either side ot the rib a7. Near the bottom form of mechanism shown and described but claim as within the scope of my invent-ion all devices readable on the claims finally all. A double acting two cylinder' reciproi eating piston pump, haring in combination two parts each containing a cylinder, means for securing said parts to each other to form a pump body, channels in the so attached side of each said part so that when said parts are united a suction chamber and a discharge chamber will be formed by said channels, a fluid passage connecting each cylinder at each of its ends with the suction chamber, a valve in each of said passages opening away from the suction chamber, a fluid passage connecting each cylinder at each of its ends with the discharge chamber, a valve in each of said passages opening toward the discharge chamber, a suction inlet connected with said suction chamber and a discharge outlet connected with said discharge chamber, a double acting piston for each cylinder and means for reciprocating said pistons.
