MEASURING AND DISPENSING VALVE Filed June 27, 1957 United States Patent l z,s9s,6ss MEAsURiNG AND msPENslNG vALvE Application June 27, 1957, Serial No. 668,362 2 Claims. (Cl. 222-452) Des Plaines, Ill., assignor to Raymond National Bank and Trust Cle/Im- The principal object of this invention is the provision of a simple measuring valve structure which is of general application and which also has operating and hygienic features especially useful in conjunction with beverage d-ispensing machines.
, Another important object is the provision of a measuring valve which has no parts contacting with the liquid measured and controlled thereby, but which acts in alternation directly at spaced points upon a compressible tube carrying said liquid from the source of supply to the point of utilization or discharge.
Additional aspects of novelty and utility characterizing the invention relate to details of the construction and operation of the embodiment described hereinafter in view of the accompanying drawing, in which:
Fig. l is a fragmentary elevational View of a coffee dispensing machine employing the new valve to dispense cream;
Fig. 2 is an enlarged fragmentary sidel elevation of the measuring valve with parts shown in section;
Fig. 3 is a fragmentary top plan view of the parts seen in Fig. 2;
Fig. 4 is a perspective detail Fig. 5 is a fragmentary perspective detail of a valve presser finger.
As viewed in Fig. 1, the new measuring and dispensing valve consists of a somewhat U-shaped frame having a base portion 10, an upright limb 11, and an overhead arm 12.
Aligned, oblong tube passages 13 (see Figs. 2 and 3 also) are provided in the arm 12 and base portion 10 adjacent Ithe conjunction with the latter of the respective ends of an upright channel section or limb 11, at which positions are provided resilient back stops 9 of rubber of like material, secured in position by an adhesive.
A pliable delivery or feed tube 14 passes through the tube passages or guide openings 13 so that the tube is somewhat attened in the region adjoining said passages and the appertaining back stops 9.
At its upper end the feed tube removably engages the nipple 15A of a spike coupling shown to larger scale in Fig. 4, and comprising a head portion 15 on which is a seating gasket 16, and above which extends a hollow spike structure including spaced piercing points 17, angularly cut away and sharpened as at 18, 19, to enter the bottom of a carton (Fig. l) containing a dispensible liquid such as cream, and adapted to seat on a bracket means 21 iixed above the measuring valve.
The head portion 15 of the spike is provided with a gasket 16 aiding to seal the spike puncture in the carton; also the periphery of the spike head 15 may be provided with screw threading 15B for removable seating in bracket 21, although for most installations it is suicient simply to drop the spike into the seating hole in the bracket and omit the threading.
of the yspike coupling; modied r"ice At its'lower end the tube 14 ts into a discharge outlet 22 above a shelf 23 adapted to support a cup 24.
Referring to Figs. l and 2, the valve mechanism includes a rockable member 25 carried on a pin 26 suppor-ted between the channel uprights 11, and each of the ends of said member includes a somewhat lateral presser extension or finger 27, 28 disposed opposite one'of the tube back stops 9, each nger being adapted to press against the intervening and pre-atted portion of the feed tube'opposite the corresponding stop member 9 when the rockable member is pivoted in the appropriate direction, as depicted in alternation in Figs. 1 and 2.
A normal spring 30 is attached at one end to the upper end of the rockable Imember and (Fig. 1) at its other end to an adjusting screw 31 carried on arm 12, so that vthe lowermost finger 28 is normally pressed against the lower tube at and compresses the same against the correponding backstop 9 to close off the tube and block escape of the contained dispensible liquid.
Means for rocking the arm 25 from the normal posi tion of Fig. l into the discharge position of Fig. 2, includes a solenoid 35 having a plunger 36 connected by a bow spring 37 (Fig. 2) to a pin 39 on the rocking arm, the other end of said spring connecting through a pin 38 to the solenoid plunger.
A snap-action is afforded by providing another bow spring 40 to the upper region of the rockable lever member 25 on the opposite side of its pivot 26 from the rstmentioned bow spring 37, the second bow spring having one end engaged with a cross pin 41 on the rockable member and the opposite end pivoted on a cross pin 42 carried between the channeluprights 11.
The solenoid 35 may be equipped with the usual internal restoring spring (not shown) in which case the normal spring 30 has merely the work of returning the member 25 and the over-center bow spring 40 to the point whereby the latter assists in the return action when the solenoid is deenergized.
In operation, the solenoid 35 will be pulsed from some control circuit (not shown) which will cause the rockable presser means 25, 27, 28 to change from the normal position of Fig. 1 to the discharge position of Fig. 2, at which time the contents of the tube 14 situated in the region between the fingers 27, 28, will be released to ow into the receptacle 24, the upper iinger 27 blocking ow from the source or carton 20 until such time as the solenoid is deenergized and the upper nger 27 disengages the tube.
The measured quantity of dispensed liquid is that quantity entrapped in the span of the tube between the upper and lower lingers 27 and 28 in each complete oscillation of the valve lever or rockable member 25.
The accuracy of the measuring action is partly dependent on deliberate full-stroke movements, in both directions, of the member 25, and on the proper location and length of the fingers 27, 28. For ordinary adjustment these fingers may be bent up or down to change to a limited extent the moment of contact and disengagement thereof with the feed tube, but further adjustment is possible with the adjustable fingers such as nger 27X shown in Fig. 5 which is slidably held by screw and slot means 50, 51, on a return ybend 52 of the stock from which the modied rockable member 25X is formed.
The valve is so constructed that the feed and measuring tube 14 may be easily removed from the passages 13 which guide and maintain the measuring portions thereof relative to the rocking presser or valve ngers 27, 28.
Moreover, the tube 14 and carton spike 15, etc, are easily removed from bracket means 21, and the tube in turn is easily detached from the spike.
For hygienic purposes the foregoing features are of great importance in a beverage dispensing machine, as
3 no-movingr valveYparts-touch the-liquid inside the feed tube, and the latter and its coupling spike may be replaced by a fresh tube and spike'upon each installation of a fresh cartn'of'cre'am, 'the' tubes either being sterilized and returned, or discarded. l
