Application June 26, 1945, Serial No. 601,635
This invention relates generally to a fluid dis-v penser but more specifically to a dispenser for milk, cream or other edible liquids wherein the delivery tube from the container is flexible and removable therefrom.
The main object of the invention resides in the provision of a fluid dispenser wherein the fluid container has a delivery nozzle at the lower part, the said nozzle being detachably engageable with a flexible delivery tube closed at'the outer end, the said tube being adapted to be removably mounted in and operatively connected to a discharge valve associated with a housing at the places of distribution of the fluid contents.
Thus, when the fluid container is at a dairy or at a place of manufacture for filling purposes it is first suitably cleaned with the delivery nozzle open. Thereafter, a flexible delivery tube closed at one end is engaged with the said nozzle preparatory to the filling operation. At the place of distribution the container is inserted in a housing provided with a discharge valve, the flexible tube being adapted to be mounted on and operatively connected to the valve, the closed end of the tube thereafter being severed to serve as a discharge port 'while the valve serves as a control for said port. When the fluid contents of the container has been exhausted at the place of distribution, the delivery tube is removed from the valve and is carried by the container after the said container has been withdrawn from the housing for return to the dairy or filling station. It is to be observed that the invention contemplates the use of a fresh and new delivery tube for each filling of the container thereby eliminating the necessity for. cleaning of the delivery tube and the valve operative thereon' Afurther object of the invention resides in the provision of a fluid dispenser wherein the fluid container is provided with balancing means cooperating with a gauge. on the door 'of the container housing to indicate to the distributor the fluid volume of the container.
A further object of the invention resides in the provision of a fluid dispenser wherein the container or fluid storage tank is provided with a delivery nozzle within a recess on a wall of the container, the said nozzle having a stopper in the form of a flexible delivery tube provided with a severable closure at the outer end and being adapted to cooperate with a discharge valve, the said severable closure serving as av dis chargepo-rt for the fluidcontents of the contailner upon severance after assembly with the vave.

Figure 15 is a view in perspective of the central bearing axis for the valve control disk members of the valve mechanism.
Figure 16 is a view in perspective of the flexible delivery tube having a severable closed end.
In accordance with the invention and the preferred form shown, a discharge valve or faucet secured to a wall 66 of housing 61 is comprised of a valve carrying casing generally indicated by numeral I and a conduit for the detachable mounting of a flexible delivery tube, said conduit being comprised of a pivoted bracket generally indicated by numeral I I, the bracket having a curved wall to form a groove portion Ila to cooperate and register with a groove I2 along the upper and curved side edge of easing ID.
A tapered flexible delivery tube l3, attached at one end to container 68 and shown in Figures 4, 5, 6 and 16 closed at the smaller end as at I3a during filling and transportation of the milk container as will hereinafter appear, is introduced in the discharge valve by raising bracket I I about a pivot 23 mounted on an attaching valve bracket I5 (Figure 8). Disposed in bracket I5 is a central and elongated slot I6 adjacent the inner end of the conduit as above described. The grooved portion I la of the pivoted bracket I and the groove I2 adjacent the inner ends are flared to register with the slot I6 as at IIb and I2a respectively (Figure 8) so that the inner end of flexible tube I3 may be manipulated for pcsitioning along groove I2 when bracket II is raised, the outer end of groove I2 extending beyond grooved portion Na and being vertically disposed and terminating in a tubular section I'l. Upper edge l8 of the tubular section I! supports the lower edge of grooved portion Ila, the outer end I3a of the flexible tube passing through I1. After the tube I3 is thus introduced pivoted bracket II is closed and the end I3a is severed below tubular section IT as indicated by reference lines in Figures 4, 5 and 6 and as shown in severed position in Figure 1. The pivoted wall portion II has a flared portion III), a web portion Hchaving an indent IId.
Pivoted wall II is secured to bracket I5 above slot I6 by means of a pair of spaced disks I9 joined by a curved extension |9a terminating off a vertical wall 2|] of bracket II. Disks i9 and extension I9u extend into a transverse slot 2 I, the inner walls of said disks I9 being in bearing contact with protruding spaced knuckles 22 of bracket I5 extending across slot 2| (Figure 11). The pintle or pin 23 for pivoted bracket II penetrates the said disks I9 and knuckles 22, the pin exposed between knuckles 22 having a plane surface 24 forming an obtuse angle with the plane of attaching bracket I5 (Figure 14). A spring urged pin 25 is mounted within an opening 25a in the solid wall portion of pivoted bracket II as by a spring 26 and nut 21, said pin having concave end 28 and being engageable with the pintle 23 for resistance to pivotal movement of bracket II. The said resistance is minimized when the concave end 28 is about to and engages the plane surface 24 of pintle 23 and this takes place when the pivoted bracket I I is forced by grasping web He at depression H d in lowered position for closure of bracket II whereupon gravity and the lessening of friction by pin 25 on plane surface 24 causes pivoted bracket II to snap into closed position.
The valve carrying casing I0 is provided with a longitudinal bore 29 extending from and through bracket I5 and terminating in and commumcating with tubular section I1 (Figures 6, 7
and 8). A hollow valve member 30 is slidably reciprocable in the bore 29, the operative end 3| being rounded and closed and adapted to enter tubular section I! and constrict flexible tube l3 therein against the inner Walls for restricting flow of fluid therethrough.
Valve member 30, in order to constrict and relieve constriction of flexible tube I3, is actuated by engagement of a transverse valve pin 32 mounted in a transverse opening 34 on lug 33 carried by valve 30, said lug 33 having a passage way 35 in the valve casing I9. Pin 32 is free to reciprocate with the movement of lug 33 in a transverse and elongated slot 36 in casing I 0, and is actuated by engagement of the projecting pin ends with a pair of curved and spaced cam slots 31 and 38 situated in a pair of spaced and parallel disk members 39 and 49 of a frame 4| provided with an operating handle 42 (Figures 4, 5, 6, 12 and 1-3).
The inner walls of disks 39 and 40 are fiat'and bear against the flat and partly circular front and rear walls 43 and 44 of casing I0, the disk members 39 and 40 of the frame 4| being mounted for rotatable movement on an axis 45 penetrating a transverse opening 45a centrally of walls 43 and 44 of casing I 0, the axis 45 being prevented from rotation by the use of a projecting pin 46 which is engageable with a corresponding notch (not shown) in the front wall 43 of casing I0. There is also an opening 48 registering with the notch in one of the disks such as disk 39 (Figure 4) adjacent one of the aligned central openings 49 and 50 to receive the central axis 45, the said opening 48 permitting introduction of pin 46 on axis 45 through the disk 39 for engagement of pin 46 with the notch in front wall 43. (Figures 4, 5).
Central axis 45 on each end is provided with a nut projection 5| and an internally threaded bore 52. Each of the disks 39 and 40 on the outer face has a mounting bead 53 and a groove 54 to receive a Bakelite cap 55 and a wire spring" 56 for resilient attachment of said cap to each disk. Each cap 55 is adapted to conceal a cover disk plate 51 having a central square opening 58 to engage nut 5|, the cap being'secured by a threaded bolt 59 engaging the threaded bore 52 (Figures 12, 13).
Valve member 30 is hollow to receive a coil spring 60, which engages the closed curved end 3| of valve member 30 at one end and at the opposite end abuts the inner end of a threaded head 62 engageable with a threaded inner end portion 63 of valve bore 29, the spring at said end surrounding a pin 6| extending from head 52 (Figure 6).
The opposite cam slots 31 and 38 in disks 39 and 40 communicate with concentric slots 64 and 65. Thus, when handle 42 is in a vertical position (Figure 7) the valve end head 3| constricts the flexible tube I3 against the wall of tubular section IT in which position the faucet or valve is closed and at which time the terminals of valve pin 32 are in forced position by spring 6|)" at the outer ends of cam slots 31 and 38 and at the outer end of slot 36. To open (Figure 6) handle 42 is drawn outwardly and the valve member 30 is forced inwardly against spring 60 by displace ment of valve pin 32 along slot 36 by the action of'cam slots 31 and 38. The limiting inward position of pin 32 in slot 36 is maintained by concentric slots 64 and 65, the ends of the latter concentric slots serving as stops for the downward movement of handle 4 In this position of thevalve, tube- I3 is unrestricted for flow; To close or restrict flow through tube I3, handle 42 is raised untilthe terminals, of the valve pin 32 enter the inner ends of cam slots 31' and 38 whereupon the force of spring 60 causes outer travel of valve pin 32 along cam slots 31 and 38 bringing handle 42 to closed vertical position with a snap.
The faucet above described is adapted to be secured at bracket I5 to the lower end of a front door 66 of tank or housing 61 for a milk or fluid container 68 as by screws 69 (Figures 1, 4, 9) penetrating openings 69a in bracket [5. The said front door 66 has an opening for passageway of the flexible tube I3. The container 8 has a lower flange H riveted to the lower end of the upwardly turned side wall Ha. A raised bottom wall I lb is adapted to be secured therein as shown in Figure 10. Adjacent flange H of container 68 and at opening 12a is a recess or housing I2, the rear wall I3 thereof communicating with the container 68 by a nipple section I4 projecting into recess I2 and having a head for engagement of the inner end of flexible tube I3. If desired, the rear wall I3 of housing I2 may also be provided with a pressure connection I6 for attachment at its outer end within the recess I2 with a pressure hose line 11, the inner end of connection I6 having a slit valve I8. The purpose of introducing pressure into container 68 is to have forced flow instead of gravity flow of the fluid contents from the container.
Before filling container 68, tube I3 closed at one end as at I3a is secured to bead I5. Thereafter, the container is filled and tube I3 is rolled or curled within the recess I2, the mouth of the recess having a circular groove 8?! for insertion of a removable seal 8 I. .As shown, the mouth of the recess may have a reinforcement member 12b therearound.
The container 68 upon being received at the place for dispensing the contents is inserted through the front door 66 of the housing 6! and supported on a floor 82 having a pair'of tilting brackets 83 with sockets 84 at the rear thereof so that the flange II of the container may fulcrum thereon for balancing against a volume gauge secured to the door. Thus, near the upper end of door 66 is a gauge having a plunger 85 adapted to support the upper and tilted part of the container 68. The plunger projects from the inner side of door 66 and is adapted to abut at the end portion 85a the forwardly tilted end of container 68, the plunger being spring urged as by a coiled spring 86 in a housing 81 (Figure 3). The outer end 88 of plunger 85 is connected to a conventiona1 pressure meter calibrated for volume and indicated generally by numeral 89 the said meter being secured to the outer side of door 66.
Upon receipt of container 68 from the filling station the Storekeeper or operator introduces the container into the tank or housing 6! through door 66 for support on sockets 84 in the tilting brackets 83 in a position whereby recess I2 faces door 66 opposite opening I0 therein when the door is in closed position. Thereupon seal BI is removed from the mouth of recess I2 and flexible tube I3 is extended outwardly. At this time the faucet or valve on door 66 is manipulated so that the operating handle 42 is in down position and the wall I I is in uppermost position. Thereafter door 66 is closed and tube I3 is withdrawn through the door opening I0 and the bracket slot I6 and set along groove I2 for insertion through tubular section II. Thereupon wall II is brought down to closed position or as best shown in Figure 6.
Thereafter handle 42' is brought up to its verti= cal position to cause. restriction in tube l3 and the closed end I3a of the tube projecting from tubular section I1 is cut off resulting in an as: sembly as shown in Figure 7.
When the contents of the container 68 are exhausted tubular handle 42 is brought into downward position and wall A is raised so that tubelS' may pass'out of the valve mechanism upon the opening of the housing door 66, the said tube I3 remaining on container 68 and being carried thereby upon the removal of the container from the housing 61.
