Claims. (o 2155- 8 This invention relates to liquid dispensers or a simple type which are adapted to be used at soda fountains and other places for dispensing liquid from a container for-fountain and other drinks, 5 and the primary object of the invention is to provide a novel and improved device, simple in construction and efficient in operation, which will uniformly dispense a predetermined quantity of liquid at each operation. r

Another object is to provide a valve adapted to be secured over the open mouth of a container substantially filled with the liquid to be dispensed and which container is then inverted and supported in position with the'valve suspended there- 15 from in convenient position for operation to discharge a predetermined quantityof the liquid into a receptacle disposed below the valve.

And a further object of the'invention is toprevent the liquid from becoming air. bound in the In the accompanying drawing illustrating a se lected embodiment of the invention. I

Referring to the drawing, the [casing 1 comprises a valve body 2 and a head 3 secured .together by threaded engagement between the head and a lug 4 on the valve body. The valve body 2 has a tapered valve plug 5 extending therethrough and the engaging surfaces are" ground to provide a snug working fit. A handle 8' is rigidly mounted on the large end of the plug 5 and a stud 9 is secured on the small endof the plug'and extends beyond the valve body andhas a reduced threaded end portion 9. A stop collar .10 is rigidly mounted upon the stud 9. A coil spring 11 is mounted on the stud 9Iand has one'end thereof fastened in the casing 1 and the other end engaged with a'retainingcoll'ar 12. The collar 12 is fixedly mounted on the stud 9 and has a plurality of holes therein for selectively receiving one end of thecoilspring llto provide any de sired tension. The collar 12 is held on the stud by a nut. 13 on the threaded end portion. ,A

lower end of the 5 stop 15 is mounted on the casing and a recess 14 V is provided in the periphery of the collar 10 to receive the stop. The stop and recess limit the extent of rotation of the valve plug. The plug is providedwith apassage 16'which is adapted to register with a passage 1'7 and a passageltl or with the passage 18 and a discharge passage 19 in the valve body. The passage 1'7 extends through the lug4 on the valve body and the head 3 to the container 20. A gasket 22 is interposed between the head and the valve body at the periphery thereof to prevent leakage. A measuring chamber 23 in the head communicates with the passage 18 in the valve body and through a passage 24 in the head with a standpipe 25 which is secured to the head and is open at its outer end and extends near thebottom of the container. The container is inverted when in dispensing'position and isthreadedly engaged with the head 3 at 26, and a gasket 27 is interposed between the container and the head to prevent leakage. A vent pipe 28 is mounted on the head and has its upper end open near the bottom of the inverted container 20 and its lowerv end in communication-with the atmosphere through the vent passage 29 in the casing. The coil spring 11" acts to retain the so plug normally in the position shown in the drawing and also acts to wedge the plug into the valve body thereby eliminating leakage around the ground surfaces 6 and :71' Toassemble' the valve with a container substantially full of liquid, the operator first locks the air in the vent pipe28 by placing his thumb over the outer end of the pipe 29 and then immersing the vent pipe and the stand pipe in the liquid and screws the head'on the container, all the whilemaintaining theair passage closed. Then the container is inverted and the air normally in the neck of the container rises to the bottom of the container which is then in up position and the operator removes A his thumb to establish communication between" the 'air in the container and the atmosphere through the vent. As soon as the air in the container rises to the bottom of the container in its up position 'and' establishes communication through the stand pipe 25 and the measuring chamber, the liquid in' the container will flow through "the passage 17, forcingthe air therefrom into the measuring chamber and from the measuring chamber and from the measuring chamber through the passage 24' and stand'pipe 25 until the chamber is filled with liquid. The liquid in the stand pipe 25-will always seek the level of the liquid in the container. To operate the valve the operator rotates the plug 5 by' -means of'the handle8 as far as the stop 15 will permit. The

and re-establishing communication between the;

container and the measuring chamber and allowing the liquid to flow into the measuring" chamber in preparation for the next operation.

The invention provides a liquid dispenser of v simple construction adapted for use at soda fountains andsimilar places which can be easily assembled for use, which canbe easily cleansed and maintained in sanitary condition and which.

is adapted for quick operation to dispense a predetermined 'quantity of liquid. A dispenser of this kind will be supported above a counter or in some other convenient position to permit a glass to be placedbeneath the dischargel9 for receiving the liquid and it is important to prevent the valve from leaking which would result in objectionable drippingfrom the discharge. For this'purpose it is importantthat the valve plug should at all times operate snugly in, its seat and my invention utilizes the return spring 11 for this purpose by causing it to maintain a constant pull on the valve plugto tighten it in itsseat;

I have illustratedand described the invention in a simple form suitable for the purpose but it may be desirable, to make changes in the form, construction and arrangement of parts to satisfy different conditions and. I reserve the right to make any such changes within the scope of the following claims:

. I claim:
