UNITED STATES WILLIAM H. ROSE, OF JERSEY CITY, NEW JERSEY.

LIQUID-DISPENSING DEVICE.

Application filed November 4, 1924. Serial No. 747,878.

To all ifi/0m t may concern:

Be it known that I, WILLIAM H. Rose, a citizen yof the United States, residing at Jersey City, county of `Hudson, and State of New Jersey, have invented new and useful Improvements in Liquid-Dispensing Devices, of which the following is a full, clear, and exact specification.

My invention relates to liquid dispensing` devices and refers particularly to devices of this character of a construction particularly adapted for use with disinfectants.

1t is frequently desirable to employ disinfectants in small. quantities at predetermined periods, the delivery of the disinfectant from a receptacle being Acaused either automatically or through manual manipulation.

The present employed methods for accomplishing these results by means of absorbent wicks is not applicable to many disinfectants, because of the absence of proper capillary power of the wick, or because of the eiect of the solution upon the wick, causing the delivery of the liquid to be uncertain or entirely interrupted.

Devices of the wick character can not be employed with soluble soap disinfectants, which rapidly decrease the capillary properties of the wick with the resultant discontinuance of disinfectant delivery.

My device overcomes these, and other, objectionable features of the present employed devices and 4presents armeans whereby disinfectants of the soluble soap class, and others, may be successfully applied.

My device includes a particularly formed valve, or valves, of such construction as to retain the liquid within the receptacle when it is not in operation, but will allow of the escape of the liquid in quantities dependent upon the amount and duration of pressure applied to the liquid within the receptacle.

1t is immaterial in the employment yof my device as to the source of pressure, which may be of manual, mechanicahelectric, or other types, as the device may be regulated to operate successfully by any means which will allow of interrupted pressure upon the receptacle contents.

The obj ect of my invention, therefore, is a liquid dispenser without wicks, or other elements depending upon capillary attraction, capable of the intermittent delivery of small quantities of liquids from a receptacle, the

delivery being` caused by pressure upon lthe. liquid within the receptacle, the device being applicable to soluble disinfectants of the soluble soap and other types of chemicals.

ln the accompanyinpr drawings illustrating modified forms of the device if my iuvention, similar parts are designated by similar numerals.

Figure 1 is a view of one forni of my device showing one means of its attachment to a supply receptacle.

Figure 2 is a broken vertical cross-section of one form of my device.

Figure 3 is a broken vertical cross-section of a modified form of my device.

Figure 4 is a broken vertical cross-section of a modified form of my device showing means for attaching and retaining the disc valve member.

Figure 5 is a verticalv cross-section showing a modified form of pressure means.

The particular form of the device of my invention, shown in Figures 1 and 2, comprises an annular receptacle having the top 10 and the side 11. The side 11 carries the inwardly extended flange 12 thus forming an opening 13. The lower portion of the inner face of the side 11 is internally threaded to mesh with an externally threaded ring 14. The ring 14 and the flange 12 thus act as a support for the rubber disc 15, producing a tight liointure. The disc 15 has a centrally positioned incision, or slot, 16, which remains closed under normal conditions but which may be opened to release liquid from within the receptacle when pressure is exerted upon said liquid.

A tube 17 is threaded within the threaded opening 18 of the top 10 and is connected to the tube, or pipe, 19 by means of the coupling 20, the tube 19 being connected to a supply receptacle 21, which need not be hermetically sealed by the lid 22. A tube 23 is threaded within a threaded opening of the receptacle and is connected to the pipe 24 by means of the coupling' 25. The tube 24 is attached to the base plate 25, to which is attached the semi-spherical rubber pressure member 26 by means of the binding wire 27.

Within the tube 17 is a flap valve member 28 having the incision 29 forming a flap valve 30, the valve allowing the downward iow of liquid from the pipe 17 when in normal position but being closed when pressure is exerted upon the under tace oit the flange valve 30.

In ope ation, the supply receptacle .contains a liquid which flows downwardly through the pipe members illing the receptacle, the valve disc l5 preventing` the liquid from passing therethrough. It the rubber member 26 be pressed, a pressure will be produced upon theliquid in the receptacle causing the flap valve 30 to close and the incision valve opening 1G to open, allowing the escape ot' liquid from the receptacle.

The design illustrated in Figure 3 is similar in construction to that described above, with the exception that the flap valve is omitted from the pipe 17 and the supply receptacle 2l is closed and air-tight. It will thus be seen that a pressure upon a rubber pressure member connected to the pipe 24 will cause the incision valve l5 to open and allow of the escape oil liquid from the receptacle.

In the device shown in Figure e, the valve disc 15 is retained in place by the angular member 3l threaded upon the outer face ot' the receptacle side l1 and having an opening 32 therein.

Figure 5 illustrates a convenient an'd etlicient pressure bulb,comprisingthe base 32 and the cap 33 having an opening 34 there` in, a hollow rubber member 35 rests upon the base 32 and has its push button 36 extended through the Vopening 34. VThe parts thereof may be so interrelated that the downward pressure of theinember 36 unt-il it is flush with the cap 33 will cause the release of a required quantity of liquid from the receptacle. j

I do not limit myself to the particular size, shape, number, or arrangement of parts, as shown Vand described, as ythese are given simply as a means for clearly describing the device of my invention.

l. In a liquid dispensing device, in combination, a receptacle having an exit opening therein, a resilient member covering the exit opening and having a slit valve therein, the slit remaining normally closed but being` capable of opening upon pressure exerted upon a liquid within the receptacle, means for retaining the slit valve over the exit opening, a liquid supply receptacle, a c'onduit connecting the supply receptacle tothe receptacle, a conduit connecting the receptacle with an intermittent pressure exerting device and a devicecap'able of exerting an intermittent pressure upon a liquid within. thc receptacle.

2. In a liquid dispensing device, in combination, a receptacle having an exit opening therein, a resilient member covering the exit opening and having a slit valve therein, the slit remaining normally closed but being capable of opening upon pressure exerted upon a liquid within the receptacle, means for retaining the slit valve over the exit opening, a liquid supply receptacle, a conduit connecting the Asupply receptacle, a check valve 'carried by the conduit allowing the flow ot liquid trom the supply receptacle to the receptacle and preventing the return of the liquid when a pressure is exerted upon a liquid within the receptacle, a conduit connecting' the receptacle with an intermittent pressure exerting device and a device capable of exerting an intermittent pressure upon a liquid within the receptacle.
