DISPENSING AND MEASURING VALVE.

' Measuring Valves; and I do hereby declare the following to be a full,

clear, and'e'xact description of the invention, such as will enable others skilled in the art to which it ap .ertalns to make and use the same.

y-mvention relates to new and useful unprovements in dispehsin or measuring valves and more particular y to that class adapted to be used for dispensing liquid soaps or similar articles and my object is to provide means for discharging'a pro-determined j ua-ntity of the liquid at each '.oper- 'ation o the valve stem.

A further object is to provide pocketsor recesses on diametrically opposite sides of the valve stemand so arrange said ockets whereby the pockets will be broug t into position to be filled or emptied by turning.

the stem a quadrant of a circle.

A further object is to provide suitable filling and discharging openings for the casing of the valve and a further object is to provide means for preventing bubbles forming in the discharge opening. Other objects and advantages will be heremafter referred to and more particularly pointed out in the claims.

In the accompanying drawings forming part of this application, Figure 1 is a perspectlve view of the valve complete. Fig. 2 1s a transverse sectional view thereof as seen on line 2*2, Fig. 1. Fig. 3 is a vertical central sectional View through the valve casll'lg Fig. 4 is a sectional view through the casing as seen on line 44, Fig. 3. Fig. 5 is a perspectlve view of the stem of the valve removed, and, Fig. 6 is a plan view of the washer used in connection with said stem.

Referring to the drawings in which simi lar reference numerals designate corresponding parts throughout the several vieWS, 1 indicates the caslng' of m improved valve, through the center of which extends a bore or socket 2, for the-reception of the valve stem 3, said bore and stem being slightly tapered from end to end as is the usual practlce. v

.tudinal center is an inlet and outlet port l and 5, respectively, the inner ends Gland of said ports be ng preferably oblong or flared upwardly or downwardly fora purpose to e hereinafter set forth. The ortion of the casin through which the inlet port 4 is extended, is provided withthreads 8,] whereby the valve may be readily attached to any suitable form of pipe or other object.

The stem iiis'pi'oviclcd on diametricallv opposite sides with pockets or recesses 9 and 10, said pockets being separated by a partition 11, which partition is substantially fan shaped at its'edges to form cut ofl's l2 vand 13, which cut oii's are adapted to cooperate, respectively, with the inlet and out let portions at and 5, the width of said cut offs being sli htly greater than the width of the inner ends 6 and 7 of the inlet and outlet port-s, respectively.

The length of the pockets 9 and 10 are substantially equal in length to the inner ends 6 .and 7 of the inlet and outlet ports.

f'wherc'by when the pocket-sure brought into registration with said ports, the discharge and intake of the liquid passing through the valve will be quickly accomplished.

The extent of the pockets 9 and It) is such that when the cut off valve is resting at one side of the inlet 4. a supply of the liquid will be deposited in the pocket '10. the cut oil '13 will be positioned at the opposite side of the outlet poi-t5- and in "position to dis charge the contents of the pocket 9 as shown by .full lines in Fig. 2 and by rotating the stem the quadrant of a circle,.the cut oil s l2 and 13 will be moved to opposite sides of their respective ports as shown by dotted lines in Fig. 2,thus bringing the pocket 9 to be filled through the inlet port. and pocket 10 in position to discharge its contents throughthe outlet port- 5, the movement of the stem being limited to the proper extent by providing a channel 1a in'thc upper end of the casin 1, in which travels a pin 15 carried by t e stem 3, the longltudmal ex tent of said. channel being such as to permit a quarter rotation ofthe stem. In this nannor, a predetermined quantity of the l1qu1d will be discharged with eachoperation of the valve stem and to guard against a greater amount of the liquid being discharged as the stem is being rotated; the

cut oils will completely close their respcctire ports while said cut offs are being:

moved from side to side of their respective ports.

It has been found by experience that the dispensing valves for liquid soap w ll become inoperative by bubbles forming across the outlet port and it has beenthe practice heretofore to provide air vents to overcome this objectionable feature, but said air vents were found to be defective. To this end, therefore, I provide a plate l6,'preferably of thin metal and positioned in the outer .tioning the same substantially at the axial center of tli'e outlet port and projecting it beyond or below the lower end of the outlet port will sever or destroy the bubbles as they are formed in the liquid running downwardly.

The upper end of the stem 3 terminates in a lever or handle 17, whereby the stem may be readily rotated when desired, while the lower end terminatesin a shank 18, a portion of which is providedwith threads 19 to receive a nut 20, while that portion of the shank adjacent the stem forms a bearing sur:

face for a washer 21 and to cause the washer to rotate with the stem and likewise the nut to rotate with the washer and thus prevent- ,ing loosening of the nut by turning the stem, the tank and washer are provided with cooperating fiattened portions as shown in Figs. 5 and 6.

In operation,'the valve is attached to any suitable form of shank or rece tacle for holding the liquid, more especia ly, li uid soap, through the medium of pipes tnot shown) or direct to the receptacle, said valves being preferably positioned over a wash basin and where a plurality of basins are arranged in juxtaposition to each other, a valvemay be positioned over each of the basins and connected to one reservoir or receptacle through various ipe sections, thus obviating the necessity 0 providing a tank for each valve.

When it is desired to obtain the soap, supposing the stem to be positioned as shown by full lines in Fig. .2, t e lever 7 'is swung to the left until the pin 15 has traveled the full length of the channel 14, thus rotating the stem a quadrant of a circle and positioning the same as shown by dotted lines in Fig. 2.

This operation disposes the filled pocket 10 in position to discharge its contents throu h tlie o utlet port 5 and brin s the pocket 9 in posit on tobe filled throng the inlet port 4-, and if a suflicient quantity of the soap is not obtained with one operation of the lever, said lever is again swung in the opposite d rection and thesupply contained in the pocket 9 discharged.

It will thus be seen that I have provided a very cheap and economical form of dispensing valve and one that will discharge a predetermined quantity or the liquid being dispensed and thus obviatin the possibility of accidentally wasting the liquid.

It will further be seen that a number of the valves may be employed and connected to one source of supply and further that the supply of liquid can be obtained with but a slight movement of the stem of the valve. It will further be seen that by forming the inner ends of the inlet and outlet ports oblong, the intake and discharge of the liquid Wlll be facilitated and that by providing the late in the outlet port, clogging of said port y bubbles forming in the liquid will be obviated.

It will be understood that when the device 1 is'placed in its operative position, the plate 16 will point downwardl What I claim is:

1, In a device of the character described, the combination with a valve having its plug member provided with a li iiid receiving pocket and a casing for sai plug having inlet and outlet ports, of means arranged substantially in the line of the axial center of the outlet port for utilizing the action of capillary attraction upon the discharging liquid.

2. A device of the character described, consisting of a valve having its casin prov ded with inlet and outlet ports, an provided with a partition arran ed in substantially the axial center of said outlet port,

said partition projecting beyond the discharge end of said outlet.

- 3. A device of the character described, consisting of a valve provided with inlet and outlet ports and a partition arranged substantially in the axial center of the outlet port and projecting beyond the discharge end of said outlet port, the projecting end of said plate being tapered to a point.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
