LIQUID DISPENSER.
Application filed September a, 1921. Serial No. 498,197.
To all whom it may concern:
Be'it known that I, ALFRED E. HOLMES, a citizen of the United States, residing at Chicago, in the county of Cook, and State of Illinois, have invented a certain new and useful Improvement in Liquid Dispensers, of whi h the tollowin' is a specification.
My invention relates to liquid dispensers and embodiesimprovements in the structure shown in my previous Patent No. 1,165,673 granted December 28, 1915. Experience with the previous form shows that leakage is diflicult to prevent, owing partially to the fact that the inlet valve makes, sliding con-- tact with the inlet port, and when the devices are made in quantity, as good commercial practice demands, it is difficult to get all samples to fit close enough to prevent leakage. As a result of my present invention it is possible to employ a tapered'or positively seating valve both for the inlet and outlet ports. This avoids the need of accurate fitting and produces at all times a tight closure. It also prolongs the life of the device, as abrasion does not cause the valves to leak.
In the accompanying drawings, which illustrate the invention, Figure 1 is a side elevation partly in section, of the complete device, showing the reservoir and its support as well as the valve mechanism.
Figure 2 is a vertical axial section of the valve mechanism showing the inlet valve in open position and the outlet valve in closed position. This is the normal position-of the parts.
Figure 3 1s similarto Figure 2 but shows the inlet valve closed and the outlet valve about to open.
, Figure 4 is similar to Figure 3 but shows the outlet valve in open position.
Figure 5 is aplan section on the line 5-' 5 Figure 4.
Figure 6 is a plan section on the line 6-6, Figure 4, and
Figure 7 is a plan section on the line 7-7, Figure 2.
Like numerals denote like parts throughout the several views. V
In the form illustrated, there is a container 1 supported upon a bracket 2 of any suitable design. The valve mechanism which embodies my invention is: mounted at the bottom of the container and includes a valve casing or chamber 3 having an inlet'port 4 at the top and an outlet port 6 at the bottom.
Said inlet port is here shown in the form of" a ring screwing into the upper end of the chamber 3. Both the inlet and outlet ports have positive seats, for example, are tapered, so as to cooperate definitely and positively with the shoulders 8 and 10 of the inlet and outlet valves respectively. The
inlet valve has an upstanding guide stem 12 which slides within the inlet port. The outlet valve -has a depending guide stem 13 i which slides within the outlet port and projects down far enough to form a handle by per end this spring abuts the. ring 4: of the Y inlet port. The chamber also contains an inner helical compression spring 18 which rests upon the outlet valve and at the upper end supports the inlet valve. For identification the inner spring 18 may be termed the cushion spring and its length is such that when the outlet valve is seated the inlet valve y will be low enoughto permit the flow of fluid through the inlet port and into the chamber 3.
Said spring, is long enough, however. to close the inlet valve before the upward-upon the valve stem 13. This comv presses the spring 16, but as the inlet valve is freeto rise, it-does not, at first, compress the spring 18. It simply causes the inlet valve to rise until it seats and closes the inlet port, as shown in Figure The parts are so constructedthat this closing action will be completed before the cut-away portions of the stem of the outlet valve rise above the valve seat 6. The consequence is that at one point during the upward movement of the outlet valve the parts will occupy the position shown in Figure 3 in which the inlet I thus making it impossible" to hold the valves in such position that fluid can descend in a continuous. flow from the container 1 out through the outlet port 6. The inlet valve closes by positively abutting its seat before the outlet valve opens. As the user continues to elevate the outlet valve, the cut-away portion of the stem thereof rises above the valve sea-t 6 and uncovers the port, thus permitting the charge of fluid within the casing 3 to emerge.
A little reflection will show the superiority of my present construction over the one shown in my said prior patent. In my present device the inlet valve is positive acting in the sense that it definitely abuts its seat instead ofhaving a sliding movement of indefinte length, as in the prior construction. The new result is made possible by making the valves in two pieces instead of one and introducing a cushion spring for transmitting motion from the outlet to the inlet valve and permitting the outlet valve to continue its upward movement after the inlet valve has been arrested by coming into contact with its seat. My present device retains all the advantages of the old and possesses the the case of a sliding cut-off, as with the inlet valve of the prior construction, constant wear increases the size of the port and decreases the size of the stem of the valve. Consequently, even if the closure is tight when the device is new, continued Wear tends to produce leakage. With the present design where the engagement of the inlet valve with its valve seat is positive, abrasion does not tend to cause leakage. On the contrary, the action is similar to that of a self-grinding valve and abrasion-simply renders the fit more perfect.
Having thus described my invention what I claim as'new and desire to secure by Lett'ers Patent is:
1. A liquid dispenser having a chambered casing having shouldered valve seats at the inner and outer ends, inlet and outlet valves adapted to abut said seats, a stem on the outlet valve having a cut-away portionadapted to permit the exit of fluid from the chamber, and a spring interposed between the two valves, said spring being short enough to permit the inlet valve to be away from its seat when the outlet valve is in contact with its seat and long enough to hold the inlet valve in engagement with its seat prior to the time when the cut-away portion of the stem of the outlet valvereaches the outlet valve seat.
2. A liquid dispenser having a container with a valve casing in the bottom, said cas ing being chambered and being provided with an inlet port and an outlet port,- said ports both having positive seats facing inward toward the chamber, an inlet valve having' a shoulder adapted to seat against the inlet valve seat and having a guide stem cut away at the side, an outlet valve having a shoulder adapted to seat against the outlet valve seat and having a guide stem cut away. at the side, the valve stem projecting through the outlet port to afford means for manipulating it, a
spring for normally holding the outlet valve ALFRED E. HOLMES.
