In Fig; 0f the drawing; the pl nger 25 and the hollow slide valve oi'sieeveis are di'sclds'ed as when retained at their outer f' mostpos itions by the @011 spring 28; the 1mm mg surface 33 of said' pump plung'rahd thelifiiiti'ng' surface 35; of said hollow siiaevaw'ofsiseveta ing engaged againstthstop piece or'jpegazi Assurning thatliduid bstance' in thebot'tle [5 also fills the lower portio'nsof the purrib fi rnber l1 and the hollow slidei 'valveoi sleeve 25 beneath the pump plunger 28 and sad plunger manually to'be depressed, a st;r s'ilie'fit' action of the coilspring- 28, the plunger" and said hollow slide valve or peeve 1111 any will ben'io'vd inwardly oi: downwardly of the bottle together as a unit until the'outer or lower end of the hollow slide valve or sleeve has engaged the interior surface of the transverse closure wall- 18. During this initial inward or downward movement of'said pump plunger and the hollow slide valve or sleeve; liquid substance willbe pushed backwardly' to an unimportant extentthrough the inlet port 22 into theinterior o-f-saidbottle.
In Figa- Z-the pum plungerand-the hollow slide valve or sleeve are disclosed situated as when said pump plunger manually has been pushed irrwardly to extent just sufli'cient to'ca-u'se the outer or lower end "or said hollow-slide'valve or'sleeve to be engaged against the interior surface of the transverse closure wall 18; the inlet port 22 tobe 'cl'osed' to passage ofliquid substance backwardly through said inlet port,.and the outlet ports 30 and 24 tube-alined: Of course, inward movesaid hollow slide valve or sleeve in response to inward movement of the hollow slide valve or sleeve, instead of by engagement of the outer or lower end of said hollow slide valve or sleeve with the transverse closure wall I8, as will be understood. Supposing the pump plunger and the hollow slide valve or sleeve to be situated as in said Fig. 2, or as when movement inwardly of the bottle of said hollow slide valve or sleeve has just been arrested by engagement of the outer or upper limiting surface of the elongated slot 29 with the stop piece or peg 32, and manual depression of said pump plunger to be continued, the pump plunger will be moved inwardly or downwardly of the bottle relative to the hollow slide valve or sleeve thus to cause liquid substance to be emitted from the discharge outlet 23 by way of said outlet ports 30 and 24.
In Fig. 3 the pump plunger and the hollow slide valve or sleeve are disclosed as when said pump plunger has been pushed inwardly of the bottle to its extreme extent so that the upper limiting surface 34 of the elongated slot 3| is engaged with the stop piece or peg 32 while said hollow slide valve or sleeve also is at its extreme inner position. Supposing the pump plunger when situated as in said Fig. 3 to be released, said pump plunger and the hollow slide valve or sleeve initially will be moved outwardly or upwardly of the bottle together as a unit, in response to resilient action of the compression coil spring 28, until the inner or lower limiting surface 35 of the elongated slot 29 of the hollow slide valve or sleeve has engaged the stop piece or peg 32. During this initial outward or upward movement of said pump plunger and said hollow slide valve or sleeve, liquid substance will be per mitted to enter the interior space within the hollow slide valve or sleeve adjacent the outer or lower end of said pump plunger by way of the inlet port 22, and at the same time the outlet port 30 will be moved out of alinement with the outlet port 24.
In Fig. 4 the pump plunger and the hollow slide valve or sleeve are disclosed situated as when said pump plunger has been moved outwardly by the compression coil spring 28 to extent just sufiicient to cause the inner or lower limiting surface 35 of said hollow slide valve to be engaged against the stop piece or peg 32. As shown in said Fig. 4, the inlet port 22 is open to the interior of the lower portion of the pump chamber I1 and the outlet port 30 is out of communication with the outlet port 24. Supposing the pump plunger and the hollow slide valve or sleeve to be situated as in Fig. 4 and outward movement of said pump plunger by the compression coil spring 28 to be continued until the parts are situated as disclosed in Fig. 1, the pump plunger will be moved outwardly or upwardly of the bottle relative to the hollow slide valve or sleeve thus to cause liquid substance to be drawn or sucked through the inlet port 22 into the outer or lower portions of the pump chamber I1 and the hollow slide valve or sleeve 25.
It will be obvious that the dispenser as illustrated and described can be manipulated to cause measured amounts of a liquid substance to be dispensed from a container such as the bottle l5. With each outward movement of the pump plunger 26, adapted to be accomplished by resilient action of the compression coil spring 28, a measured quantity of the liquid substance will be loaded into the dispensing device, and
with each inward movement of said pump plunger, adapted manually to be accomplished, a measured quantity of the liquid substance will be removed from said dispensing device. The discharging operations will occur with movement of the parts of the dispenser from their positions as in Fig. 1 through their positions as in Fig. 2 to their positions as in Fig. 3, and the re-loading operations will occur with movement of the parts of said dispenser from their positions as in said Fig. 3 through their positions as in Fig. 4 to their positions as in said Fig. 1.
