Nov. 5, 1940. s. KREESBERG MEASURING AND DISPENSING DEVICE Filed Sept. 2, 193s INVENTOR SIMON KRE/SBfRG A TORNEY Patented Nov. 5, 1940 UNITED STATES PATENT OFFICE 2,220,605 MEASURING AND DISPENSING DEVICE Simon Kreisberg, Brooklyn, N. Y. Application September 2, 1938, Serial No. 228.077

1 Claim. (01. 221-116) This invention relates to devices for dispensing a measured quantity of liquid such as cream, being particularly adapted for use in restaurants, cafeterias, etc.

When it is realized that devices of this type must be kept clean and free. from the acids formed in dried milk and cream, and that for this reason they must be dismantled and thoroughly cleaned quite frequently, it will be apparent that simplicity of construction and ease of assembly and disassembly are important characteristics. Hence, the primary object of this invention resides in the provision of a device of the character contemplated which is simple of construction and may quickly and easily be assembled and disassembled for thorough cleaning of the parts thereof.

The invention also contemplates. the provision of means for mounting said device on a liquid container in such a manner as to enable said device to completely drain said container and thus obviating the necessity of tilting or otherwise seeking to completely drain said container.

Because of the peculiar properties of the liquid which is to be measured and dispensed by the contemplated device, it is desirable to agitate said liquid and for this purpose, the device is constructed to cause a rapid release of a bubble of air of considerable size through said liquid, during each dispensing operation of said device.

In order to realize the advantages above .set forth, the present device is constructed in the form of a cock, the body of which is provided with diametrally opposed chambers or pockets, and the key of which is provided with registering recesses, said pockets and recesses being formed as wide as it is possible in the structure. Thus, a rapid release of liquid is afforded during dispensing and a similarly rapid release of the air trapped in one of the pockets to cause 'agitation of the liquid in the container is also afforded.

In keeping with the purposes of the invention, the key of the cock is spring-pressed into its tapered seat in the body of said cock by a simple plate which may be associated with said body as by means of bayonet and slot connections. It is obvious from the foregoing that rapid dismantling and re-assembling of the device is afforded.

With the above objects, features, and advantages of the invention in mind, and with others which will later become more readily apparent, reference is now had to the accompanying drawing in which is illustrated a preferred form of device as at present contemplated. The following detailed specification is descriptive of said device.

. In the drawing:

, Fig. 1 .is a longitudinal sectional view through 5 a measuring and dispensing device, incorporating the features of the invention.

( Fig.2 is a plan sectional View thereof, as taken onjthe plane of the line 22 of Fig. 1.

Fig. 3 is a similar view on the line 33 of 1 Fig. ,1.

Fig. 4 is a vertical sectional view with the cock taken at right angles to the plane of Fig. 1.

In that practical embodiment of the invention illustrated in the drawing, a container such as lll for liquids or the like is preferably formed withan opening at the bottom thereof and adjacent its front wall. The container is provided with a fitting l2 having a passage I3 in register with the mentioned opening, II and provided with aninternally threaded lateral extension M. It can be seen from this arrangement that all of the liquid in the container Ill may be drained through the passage l3. H

,The cock, generally designated l5, in the presout instance comprises a body l6 provided with a tapered seat H for the key [8. The key is resiliently compressed into its seat as by means of a coil spring [9 held under compression by a collar 20 around the Shaft 2| of the key 18, said collar being engaged by a cover plate 22 preferablyformed with bayonet pins 23 engaged in bayonet slots 24 in the cock body I6. From the foregoing, it is obvious that ready dismantling of the key from the body may be had by a simple, partial turn of the plate 22 and that said plate 22 through the medium of the collar 2|] and spring I9 effectively positions the key 18 on its seat in the cock body.

It is desirable to limit the rotational movement of the key in the'body and for this rea-, son said key is formed with a projecting pin 25 on its upper portion, Said pin being movable in an arcuate cut-out 26 formed in the body and cooperating with the abutments 21 and 28 of fect the measuring accomplished by the device, it is essential that they have similar capacities, and for this reason their similarity of size and shape simplifies the construction of the cock and obviates the trial and error method of obtaining similar relative capacities.

As herein contemplated, the cock body I6 is preferably provided with two diametrically opposed pockets or chambers 32 and 33, these chambers being so arranged as to be sealed from each other by the key in any position of its rotation. The heights of these pockets in this instance are substantially the heights of the recesses in the key.

At right angles to the pockets 32 and 33, and

in line with each other, there is formed in the cock body an inlet passage 34 and an outlet nozzle 35. The former is formed with a threaded extension having engagement with the threaded seat l4 formed in the fitting l2. It will be noted that the passage I3 in the fitting l2 and the inlet passage 34 provide for an uninterrupted flow of liquid toward the throat 36 in said passage 34, said throat being substantially elliptical in shape, but of a similar area to the area of any portion of the mentioned passages. Both the throat 36 and the initial portion 31 of the nozzle 35 are also made of the same height as the heights of the recesses 30 and 3| and of the pockets 32 and 33. In this manner unrestricted flow of liquid through the cock is obtained and as a corollary to the action, unrestricted flow of air trapped in either of the pockets 32 or 33 is obtained.

In order to assist the rapid discharge of liquid through the nozzle 35, said nozzle may be vented as at 38. To insure against inadvertent dislodgement of the cock body extension in the fitting I 2, said body may be locked to said fitting as by means of a lock nut 39.

Assuming the position shown in Fig. 3, the passage 34, its throat 36, the recess 33 and the pocket 32 are filled with liquid from the container [9; and the nozzle 35, its upper portion 31, the

\ recess 30 and the pocket 33, having discharged a quantity of liquid, are now air-filled. The pin on the key is against the abutment 21 of the arouate slot 26, and the device is ready to dispense a quantity of liquid from the mentioned liquid-filled passages, recesses, and pockets. The handle 29 is now turned to bring the pin 25 into engagement with the abutment 28. The key [8 is thus turned to communicate the pocket 23 with the discharge nozzle 35 through the medium of the recess 3|. A measured quantity of liquid is thus cut off by the key and dispensed through said nozzle. Simultaneously, the key serves to communicate the passage 34 with the pocket 33 through the medium of the recess 30 and to seal said pocket 33 from the nozzle. It will be realized that the air trapped in said pocket 33 and recess 30 will seek egress through the passage 34. Be-

cause of the generous design of the passages and recesses, no retarding effect to the movement of this air will be had, and as the liquid from the container seeks to fill the pocket 33 and recess 30, said air will rapidly seek its way through the liquid in the passages 34 and I3 and through the bulk of the liquid of the container ID. This rapid discharge of air through the liquid causes a desired agitation thereof, so that the lighter molecules may not remain on top but will become thoroughly mixed with the heavier molecules of liquid. Thus, at each dispensing of a quantity of liquid, the liquid in the container is thoroughly agitated. It is obvious, of course, that the reverse movement of the handle from its last-mentioned position effects an exactly similar mode of operation, and thus each movement of the handle serves the double function of dispensing a measured quantity of liquid and agitating the liquid in the container.

It will be noted that the measuring and dispensing device is arranged so that the axis thereof is disposed at an angle to the vertical and that the discharge nozzle 35 is arranged at an angle to the body. With this arrangement, the discharge nozzle is directed substantially vertically so that liquid passing therethrough is rapidly discharged and directly so, into a receiving vessel such as a cup, or the like, having a limited diameter.

While the device as above described is preferred, it is obvious that immaterial changes therein seeking to obtain the results set forth, may be made without departing from the general scope and spirit of the invention. Hence, the prior pertinent art rather than the instant specific disclosure should form the basis of interpretation of the invention as claimed.

What I claim as new and desire to secure by Letters Patent, is:

A measuring and dispensing device comprising a key having a pair of opposed notches of a height greater than the width and depth thereof, a body in which said key is seated for limited rotation in both directions, and means for yieldingly holding said key seated in the body, said means comprising a compression spring, a collar set thereover, and a cover plate engaged with said collar and having separable connection with said body, said body being formed with opposed pockets of substantially the height of the notches in the key, with an inlet passage between and at one side of said pockets, and with a discharge nozzle between and at the other side of said pockets, said nozzle being disposed at an angle to the axis of the body and the body being arranged at an angle to the vertical whereby the discharge nozzle is substantially vertically disposed for rapid discharge therefrom of liquid into a receiving vessel.
