REMOVABLE PINcH-cocx VALVE ASSEMBLY Filed June 1'7, 1954 United States Patent LIQUID DISPENSINGv CABINET WITH READILY REMVABLE PINCE-COCK VALVE ASSElVIBLY Lann-ie F. Norris' and David I. W. Timmers'man, Minneapolis, Minn., assignors toNor'ris Manufacturing Company, Minneapolis, Minn., a corporation of Minnesota Application June 17, 1954',` Serial No. 437,404 11 Claims. (Cl. 137-376) This invention relatesA generally to liquid. dispensing cabinets and particularly to a cabinet provided withV a readily removable pinch-cock valve assembly specifically constructed to facilitatechanging liquid containers enclosed in said cabinet.
While the invention disclosed and claimed in our prior patent, No. 2,601,319, entitled Liquid Dispensing Cabinet, issued in the United VStates Patent Oice on June 24, 1952, has worked very satisfactorily, our present inventionis an improvement thereon and is designed to further facilitate changing of thevliquid containers housed within said cabinet by providing a readily removable and separablepinc'ncock valve assembly which may be easily cleaned and which provides a positivel'ock for the valve assembly for safe, over-night storage.
It is therefore an object of our present invention to provide a liquid dispensing cabinet wherein liquid confining containers housed within 'the cabinet may be quickly and easily changed.
It is another object to provide a liquid dispensing cabinet specifically designed for refrigerating the liquid stored therein and provided with a pinch-cock valve assembly for controlling the liquid discharged from a container housed within the cabinet while permitting said valve assembly to be readily removed and disassembled for easy 'cleaning thereof.
It is a further object' 'to 'provide `a liquid dispensing cabinet provided with a 'pinch-cock type valve assembly having a portion thereof actuable only from within vthe dispensing cabinet and another portion actuable from outside the dispensing cabinet to permita ilexible liquid dispensing tube to 'be controllably opened and closed with said valve assembly being arranged so that closing ofthe tube by the actuating portion disposed within the cabinet will prevent dispensing 'of-liquid by actuation of the .portion disposed outside the cabinet.
It is still another object to provide a liquid dispensing cabinet having a valve mounting assembly with a'pair of pinch-cock valves mounted thereon, one -of said valves being spaced above the other with the upper valve being disposed within the cabinet and the lower valve lbeing disposed outside the cabinet, said valve mounting assembly receiving a flexible discharge tube therethrough to permit controlled llo'w by actuation of said valves, said lower valve controlling the flow only when said upper valve is open.
It is a still further object to provide a liquid dispensing cabinet for housing a liquid container and provided with `an extremely accessible tube-receiving valve mounting member, greatly facilitating changing of the liquid cony-tainers in the cabinet by facilitation of the mounting of the elongated flexible dispensing tube therethrough and arrangement of the valve mechanisms in operative controlled position with respect to said tube.
These and other objects and kadvantages of our invention will more fully appear from Ithe following description made in connection with the accompanying drawings, wherein like reference ch-aracters refer to the same Patented Sept. 17,1957

As `illustrated in the accompanyingdrawings, kwe provide a cabinet Shaving afb'ottom panel 5a, sidepanels 519 rear panel S'c yand a 'top panel 5d Vand provided with a closure door 6 'generally 'similar to the cabinet disclosed in our previously identified patent. The bottom 5a4 has a step 7 'formed along 'the front marginal edge portion thereof. n The tjop 'surface 8a 'of said s tep isr inclinedrearwardly from 'therjextrem'e forward edge thereof, and the bottom surface 8b thereof is also inclinedv rearwardly from the 'extreme forward edge thereof,.as best showny inA Fig. 4. The central portion of the step 7` has arecess, formed therein to receive `a mounting and anchoring mem-- ber designated as an l'entirety by the numeral 9. `Said.
member 9 has a pair of' cooperating, inclined anges, respectively designated by the numerals 9a and 9b fory respectively engaging in lapped relation, the top and bottorn surfaces v8a and 8b of step v8. Suitable means forl anchoring saidY lflanges to the 'step is provided, such Vas the Set screw element 10 thread'edly inserted through the lower flange 9bto pull the upper ange 9a .tightly against the top step surface 8a.4 The, mounting member 9 has a vertically disposed passage 11 formed therethrough as best shown in Fig. 4 wherein 'the center portionsl of the insert and exible tube are broken away, said passage 11 extending from the top thereof tofthe bottom of the mounting member. "Said passage is generally cylindrical in cross section "but the front portion 11a thereof is open and unobstructed from top to bottom, to .provide complete access to the passage 11 from the front 11a. An elongated insert member V1.2 lhas a cylindrical segment which '-is rotatably mounted in the cylindrical port-ion of said passage 1'1. v Said insert member defines a passage 12a therein and the upper end` of Vinsert member 12 has an enlarged abutment fla-nge body V13 which houses a manually operated, upper Valve mechanism designated as anentre'ty Ab'y the numeral 14 and is best shown in -Fig. 5. The upper Valve mechanism 14 has a tube-engaging and pinching ielement 14a slidably mounted in a horizontally to the axis of the passage 12a defined within lthe insertA member 12. Obviously, oscillation of the "handle -1`4c on its axis will swing actuating eccentric pin 14b through? a circumferential are and said .pin being mounted in an elongated slot 14d in the tube-engaging, pinching element 14a positively shifts said tube-closing element 14a into and out of closing position. The lower portion of valve mounting and anchoring member 9 has a pair of horizontally disposed pin-receiving recesses 15 formed on opposite sides thereof. Each of said pin-receiving recesses or apertures 15 has a pin-camming surface 16 extending forwardly and inwardly therefrom whereby a pair of opposed, spring pressed pins 17 mounted in an upwardly extending portion 18a of a weight member 18 can be easily inserted into said apertures 15. Said weight member 18 has a forwardly extending weight arm 18b fixed thereto and in the form shown, disposed a slight distance below the vspring pressed pivot pins 17 of said weight. A tube-engaging pincher 18e extends rearwardly or inwardly in spaced relation below said spring pressed pivot pins and is disposed below the lower extremity of insert member 12 to pass through the access opening 11a formed in the front of passage 11 to engage a tube 19 received through said passage and pinch the same together, as best shown in Fig. 4, the weight arm 1817 of course, providing sufficient closing force to positively close said tube 19. The upper rear portion of weight member 18 is bifurcated to provide a pair of horizontally opposed, pin-mounting bosses 18d, within which lthe pins 17 and pressure springs 17a are housed.
The tube-engaging closure element 18e fixed in rearwardly extending relation to the lower portion of Weight member 18 has a pair of stop shoulders 18e for engaging the front face of the lower portion of mounting member 9 to positively limit the inward shifting movement of said pincher element and prevent cutting of the tube thereby.
The following is the description of the assembly and operation of our new valve assembly.
With the insert 12 received in the mounting member 9, which of course has been previously secured to the front step by screws 10, the tube 19 from the liquid container C supported on the bottom 5 of the cabinet, can be easily inserted into the tube-receiving passage 12a when said insert member 12 has the opening thereof disposed in registration with the front opening 11a of mounting member 9. During this operation of course, the pinch-cock valve weight 18 is removed from the lower portion of mounting member 9 by retracting spring pressed pins 17 from their yrespective apertures so that the tube-receiving passage 12a is completely accessible throughout its entire length and said tube 19 can easily be mounted therein.
In practice, the tube 19 has the lower portion thereof sealed by any suitable means such as a positive vulcanized plug member being received therein and this closed end must of course be severed from the upper portion of the tube in order to permit the liquid to pass from the container C downwardly through the tube. It is of course possible to cut o this tube closure before mounting the valve weight 18 back onto the mounting member 9 by closing the upper cam actuated pinch-cock valve 14. However, in normal practice, the weight 18 is assembled on the mounting member before the tube closure is cut therefrom and normally holds the tube in closed position, as shown in Fig. 4. However, raising of the weight arm 18b will of course remove the tube-engaging pincher element 18e` from the tube and permit liquid to be discharged therethrough as long as the upper valve 14 is in open position.
It should be pointed out that the tube 19 can be completely surrounded in protected relation by rotating the insert member 12 `through 180 degrees to close the opening 11a with a closed segment of said insert and position the opening of said insert at the rear of the passage through said mounting member. The upper end of said mounting member has a substantially horiz-ontally disposed bearing portion which receives and engages the lower surface of the flange body 13 to support said insert in outstanding relation while permitting rotation thereof within said mounting member.
The distance across the opening 11a at the upper portion of the mounting member is slightly less than the diameter of the passage therethrough, thus positively retaining the insert member therein since the outside diam- -eter of the cylindrical segment of the insert member is substantially the same as the inside diameter of the passage through the mounting member.
It will be seen that we have provided a relatively simple yet highly eiiicient liquid dispensing cabinet which may be of the refrigerated type to house relatively large containers of milk or other liquids and facilitate dispensing thereof while maintaining the same in a cool condition. With the door 6 of the cabinet open, the container C may of course be easily lifted onto the cabnet bottom 5 and the tube 19 inserted into its confining passage as has been previously described and said tube completely enclosed in said passage, as described.
Wheneverv a container is changed, the insert member and weight-operated pinch-cock valve structure may be completely removed from the mounting member and thoroughly washed before being reassembled. The cornplete and unobstructed accessibility to the tube-receiving passage when the openings in the insert member and mounting member are brought into registration along with theremovability of the Weight-operated pinch-cock valve structure, greatly -speeds up changing of the containers within the cabinet and facilitates cleaning of the assembly. The parallel, front surfaces of the mounting member receive the sealing gasket 6a of the door 6 so that the complete peripheral area of the door 6 will be substantially sealed. The upper valve assembly mech- `anism 14 is of course housed within the cabinet behind the door 6 and when the door is closed and locked, said valve will be inaccessible from the outside, thereby providing an easy land quick means for locking the dispensing mechanism if desired, to positively prevent stealingof the milk or other liquid.
It will of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of our invention.
