DISPENSING-VALVE.

Specification of Letters Patent. A P t t d Ap 192il Application filed December 16, 1919. Serial No. 345,418.

T 0 all whom it may concern:

Be it known that I, CHARLES P. Bossnn'r, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements 1n DlS- pensmg-Valves; and I do hereby declare that the following is a full, clear, and exactdevscription thereof.

operation to eject a certain limited quantity of liquid upon each actuation of the operating member of the valve, and to prevent leakage through the valve after a certai amount of liquid has been discharged.

'Such valves are usually provided with a measuring chamber in which is disposeda plunger to procure ejection of the limited amount of liquid, the valve member being adapted to operate by reason of the velocity flow of liquid to either close off flow of liquid from the reservoir into the valve, or from the measuring chamber through the discharge port of the valve. i

It is a furtherobject of my invention to provide an arrangement wherein the plunger, upon movement in either direction, imparts an initial movement to the valve member so as to reduce the liability of sticking of the valve member.

With the above and other objects and advantages in View, which will beapparent as the description proceeds, my invention resides in the novel features of construc tion, combination and arrangement ofparts which will be hereinafter more particularly described and defined by the appended claims.

In the accompanying drawings: Figure 1 is a longitudinal sectional view through a soap dispensing valve constructed inaccordance with my invention.

Fig. 5 is a similar view on a plane indicated: by the line 5-5 of Fig. 1.

:Fig. 6 is an inner end view of the valve.

Referring now more particularly to'the accompanying drawing, my improved valve structure comprises an elongated cylindrical casing 10 divided in its intermediate portion by a relatively wide partition 11 to form a measuring chamber Aat its outer portion, and a valve chamber 13 at its inner portion, the partition being providedwith a central aperture to permit communication between the chambers. The outlet port 12 of the valve extends obliquely through the bottom of the wall'of the main casing 10 at its intermediate portion and opens at the" inner side of the partition 11. pluglS is threaded in the valve chamber end of the casing and is of longitudinal inlet ports l 't and with a nipple portion 15 whereby the valve may be secured to any suitable reservoir orother source of supply. A stem 16 is slidable axially in the plug 15 and is extended through the chambers of the casing and the partition 11, said stem being threaded into the inner end of a plunger 17 which-is slidable in the measuring chamber end of the casing.

A spring 18 is coiled on the stem within the measuring chamber A and bears against provided with a plurality the plunger and against the partition 11,

outward movement ofe the plunger being limited bya head 19 on the inner end of the stem 16, said head being adapted to to close the inlet passages 14 of the plug.

A sleeve 20 is slida bly mounted on the stem 16 within the valvechamber B and isprovided at one end with a radial flange 21 adapted to engage against theplug 13 and close the inlet ports 14, said sleeve being also provided with a series of longitudinally extending radial ribs 22 which project beyond the other end of. the sleeve and carry a disk 23 adapted to seat against the adjacent face of the partition 11 and close the outlet port 12, said disk being provided with a central aperture of such diameter as not to interfere with free passage of liquid between the chambers. I V

Entering now into the operation 01" my improved valve structure, it will be seen that the plunger 17 which constitutes the operating member of my valve and is therefore provided with a suitable headfZei at its outer end, is normally disposed outwardly and the headed end 19 of the stem 16 is urged against the plug 18 to provide a positive closure pre venting passage of liquid from the reservoir. The disk 23 is also engaged against the partition 11, thus closing the discharge port 12 of the valve and a certain amount of liquid is contained within the measuring chamber A and the valve chamber B. To actuate the valve, the plunger 17 is moved inwardly and in this inward movement of the plunger the valve member will be carried on the stem 16 thus uncovering the discharge port 12 and seating the flange 21 against the plug 13 to close the inlet ports 14-. The amount of liquid displaced by the plunger 17 in its inward movement is thus forcibly ejected from the valve, and when such ejection has occurred, the valve member will slide on the stem to close the discharge port 12 by reason of flow of liquid from the reservoir. This movement is however more thoroughly eilected when the plunger 17 is normally released after being moved to its inward limit of movement, thus causing the plunger to move outwardly under the action of the spring.

" As the plunger moves outwardly, it will draw a successlve charge of liquid into the measuring chamber, the flow of fluid in either direction through the valve chamber serving to move the valve to its selective closing position by impinging against the flange and disk portions of the valve member.

I have thus'provided an exceedingly simple and efficient dispensing device in which, upon movement of the plunger in either direction the flow of liquid to and from the measuring chamber effectively imparts the desired moving impulse to the valve member which is reciprocably mounted on the stem of the plunger. It is noted that in the normal closing position of the valve, a double seal is afforded against leakage through the valve, by the disk 23 and stem head 19.

lNhile l have shown and described a preferred embodiment of my invention, it will be appreciated that various changes and modifications of structure may be employed to meet differing conditions of use and manufacture without departing in any manner from the spirit of my invention.

What is claimed is:

A valve structure of the class described comprising a storage chamber, a valve cham ber in communication with the storage chamber, a valve member reciprocable in the valve chamber, inlet and outlet ports for the valve chamber, a plunger having a stem slidable in the measuring chamber, said valve being slidably mounted on said stem and operable by the flow of liquid upon reciprocation of the plunger to open and close said ports successively.
