LIQUID DISPENSING DEVICS Fileqmay 24, 1957 LHQUID DSPENSENG DEVICES .loseph Crowder, Dunbar, W. Va. Appiication May 24, 1957, Serial No. 661,522 7 Claims. (Cl. Z22-426) This invention relates to liquid dispensing devices, and more specifically, the present invention pertains to dispensing means for dispensing a plurality of predetermined liquid volumes.
One of the primary objects of this invention is to provide a liquid dispensing device of the type referred to above with valve control means for controlling the dispensing of one of two known liquid volumes independently of each other.
Another object of this invention is to provide a liquid dispensing device for dispensing two known liquid volurnes, the dispensing operation being done in sequential order.
A further object of this invention is to provide a liquid dispensing device as described supra with a plurality of liquid containers served from a common reservoir together with valve means for cutting off the liquid supply from said reservoir to the containers as the liquid is dis pensed therefrom.
It is a still further object of this invention to provide a liquid dispensing device which is noncomplex in construction andassembly, inexpensive to manufacture, and durable in use.
Other and further objects and advantages of the present invention will become more manifest from reading of the following specification in the light of the annexed drawing, in which:
` Figure 2 is a fragmentary detailed cross sectional view taken onV the horizontal plane of line 2 2 of Figure 1, looking in the direction of the arrows;
Figure 3 is a fragmentary detailed cross sectional View taken on the vertical plane of line 3-3 of Figure 1, looking in the direction of the arrows; p
Figure 4 is a detailed cross sectional view taken on the horizontal plane of line 4-4 of Figure 1, looking in the direction of the arrows;
Figure 5 is a cross sectional view of the liquid dispenser similar to Figure l, the dispensing valve, however, being shown in one of its open and dispensing positions; and
Figure 6 is a cross sectional View similar to Figure 5, Figure 6 illustrating the dispensing valve as being raised to its second operative position.
Referring now more specifically to the drawing, reference numeral 10 designates, in general, a dispensing device constructed in accordance with the instant invention. The dispensing device 10 is seen to comprise an open ended cylindrical reservoir l2 including a bottom wall 14 having an integrally formed and substantially upright annular side wall 16.
The bottom wall 1.4 is provided with an enlarged centrally positioned aperture 18 having a depending annular boss Ztl which serves a function to be described below. The bottom wall 14 is also formedwith an offset transpatented July s, sV
versely extending opening 22 in which is xedly secured one end of a substantially vertically extending hollow cylindrical air vent tube 24.
The upper end of the reservoir 12 is provided with a substantially circular closure member 26 supported on the upper end of the side wall 16, the closure member 26 including a depending annular flange adapted to bear against the side wall 16 adjacent its upper end. As is clearly seen in Figure l of the drawing, the closure member 26 is provided with a centrally disposed aperture 30 surrounded by an upwardly projecting substantially hollow boss 32. A substantially hollow tubular element 34 depends from the closure memberf26 into the reservoir l2 and is coaxially aligned with the opening 30. For reasons to be made clear below, the hollow tubular element 34 is provided with a substantially rectangular bore 36 which extends throughout its length. The closure member 26 is also provided with an offset opening 38 and an integrally formed vupwardly projecting ange 4t). The ange 40 is internally threaded to receive the externally threaded end 42 of a removable cap 44 having a centrally positioned transversely extending air vent 46 formed therein.
A shaft S6 is mounted for reciprocation within the conduit 48 and projects upwardly therefrom through an aperture 58 formed in the closure plate 56 and through the aperture 18 formed in the bottom wall 14 of the reservoir 12. The upper end of the shaft 56 is externally threaded at 60, the threaded end 60 being, threadedly received within a knob designated by reference numeral 62. The knob 62 is provided with an integrally formed depending projection 64 which is adapted to bear against the boss 32. As is seen in Figures 1 and 4, the shaft S6 adjacent the inner end of the thread 60 is provided with a longitudinally extending substantially rectangularportion 66 which is slidably received in the bore 36. Thus the hollow tubular member 34 and the rectangular portion 66 of the shaft 56 cooperate to prevent the shaft 56 from turning as the knob 62 is rotated in a clockwise or counter clockwise direction.
A valve 68 is mounted on the lower end of the shaft 56, the valve 68 abutting against a washer 70 which is retained in place by means of a nut 72 threaded on the lower end of the shaft 56. A helicoidal spring surrounds the lower end of the shaft 56 and one of its ends abuts against the closure plate 50 and the other end thereof bears against the valve 68. The arrangement of these elements is such that the spring 74 constantly tends to urge the valve 68 for movement away from the closure plate 50.
A collar '76 is xedly secured on the shaft 56 by means of a set screw 78. As is seen in the figures, the collar 76 serves as stop means for limiting downward movement of the valve within the conduit 48.
One end of a helicoidal spring Si) feeds against the upper side of the washer 76. The helicoidal spring Sil also surrounds the shaft 56 .and the upper end thereof supports a valve 82 which is freely mounted on the shaft 56.
A substantially hollow cylindrical liquid container is designated by reference numeral 84. The container S4 is provided with a bottom wall S6 h-aving an inverted substantially. frusto-conical configuration. The bottom wall 86 is centrally apertured to receive therethrough the upper end of the conduit 48. As is seen in the figures, the bottom wall 86 is welded at 38 to the conduit 43 intermediate the vertically spaced series of apertures 52 and 54.
A second container 90 surrounds the container Sd in spaced relation relative thereto. The container 96 is also provided with a bottom wall 92 having a truste-conical configuration. The bottom wall 92 is provided with a centrally disposed aperture to receive the conduit 43 therethrough. The bottom wall g2 is secured to the conduit 4S immediately below the circumferentially spaced apertures 52 by means of welding 94. Welding 94, or any other suitable conventional supporting means such as screws, brackets, etc., secures the upper end of the container 90 to the underside of the bottom wall i4 of the reservoir 12.
Any conventional supporting means such as, for example, a bracket 98 may be employed to permanently locate the dispenser 12 at a desired point.
Figure l illustrates the relative position of the component elements of the dispenser under nondispensing conditions. As illustrated therein, the valve 68 is disposed below the lowermost series of circumferential apertures 52 and the valve 32, is in its open position relative to the valve seat 29. Under these circumstances, lliquid is free to fiow from the reservoir 12. through the opening ii-,- and into the container 84. As the container Se becomes filled the same will overflow into the container 90. Liquid continues to ow from the reservoir i2 until both containers are completely filled.A It will be understood, of course, that the volume of the containers S4 and 90 have been predetermined.
Let it now be assumed that the operator desires to dispense only that liquid which is disposed within the conainer 9G. To affect this dispensing operation, the operator rotates the knob 60 in a clockwise direction causing the shaft 56 to rnove upwardly. This movement is continued until the valve 68 is interposed lbetween the two series of apertures 52 and 54. Thus the liquid disposed in the container 90 flows freely through the apertures 52 and into the upper end of the discharge or dispensing conduit 4.
Simultaneously with the opening of the apertures 52, the upward movement of the shaft 56 forces the valve S2. to seat against the valve seat and to thereby prevent any additional fluid from entering the container 96.
After all of the liquid has been discharged from the container 9), the operator then turns the knob 62 in a counterclockwise direction moving the shaft 56 downwardly until the valve 68 is positioned once again within the conduit 4S at a point below the first series of apertures 52.
lt should be pointed out at this time that as the valve S2 seats against the valve seat Zit and as the knob 62 is rotated still further, the spring Si) is compressed between the valve 82 and the collar '76. This is an important feature of the invention for, as the knob 62 is rotated in a counterclockwise direction, the spring 3i? maintains thc valve 82 closed against the valve seat 26 until the valve 72 has been moved to its closed position as is shown in Figure 1.
Let it now be assumed that the operator desires the tetal volumes of the containers-Lt and 99. Under these conditions, the knob 6a is rotated in a clockwise direction to `effect an elevation of the shaft 56, as described above. However, the knob 62 is rotated a number of more revolutions to cause the valve 68 to pass upwardly beyond the two series of circumferentially spaced apertures 52, 54.
Again, `the valve S2 is compressed against the valve seat 2t) by the spring tit) and thereby prevents the flow of fluid from the reservoir into either of the two containers. After the contents of both containers have been dispensed through the tubular member #i8 the knob 62 Y device it is clear that the operator need not completely exhaust the liquid contents of the container 96. Any part or all of the liquid disposed within the containers may he utilized. Additionally, it should also be understood that after the contents of the first container have i been exhausted, it is not necessary for the user to completely exhaust the contents of the second container. The valve may be oper ted in such a manner to obtain the desired volume of liquid.
