Application filed October 2,1826. P Serial No. 139,098.

This invention relates to a device for dispensing liquids and has for an object to provide means for dispensing a predetermined quantity of a liquid drink.

Another object is to provide a means for holding and storing a quantity of a hot or cold 1i uid in a manner to maintain a substantia ly constant temperature, in combination with means quantities 'of said liquid, said means being located substantially entirely within said holding means; i A

Another object is to provide a measurin device located within-a main reservoir an having inlet-and outlet valves and means operable in unison with said valves for venting said device to facilitate flow of liquid therefrom.

A further object is to provide a liquid dispensing device comprising a valve operating lever in combination with a coin controlled lock for said operating lever.

A further object is to provlde a coin controlled dispensing device which is simple in construction, eflicient in operation and economical to manufacture.

Other objects will appear from the detailed description which follows.

In the drawings,-

Figure 1 shows a side elevation of the device partly in section;

Fig. 2 is a view in section of the measurlng device and related parts;

Figs. 3 and 4. show the co-operating valve ports in the inlet valve plate and measuring container; I

Figs. 5 and 6 show two different positions of the outlet valve and operating lever;

Fig. 7 shows the coin controlled locking lever in three working positions; and

Fig. 8 shows the mainop erating handle in two operating positions together with the rotatable supporting block for said handle.

Referring to thedrawings, numeral 1' indicates a. main reservoir or liquid container which is preferably a thermos jug properly constructedto maintain the confined liquid at a constant temperature for a reasonaple period. Said reservoir is supported in an inverted position on a frame comprising a ring 2, legs 3, and based. A platform 5 carried by legs 3 supports a coin controlled looking mechanism which will be described in detail hereinafter.

As best shown in cap 6 of the container Fig. 2 the usual screw 1 supports all of the to dispense measured elements which comprise the means for meas uring and feeding predetermined quantities; of the liquld. A disk like supporting base 7 made of brass .or other non-corroding 'material and hav ng a downwardly extending tubular extension 8 is arranged in said cap and an opemngQ 1s provided in-said cap to rece1ve the extension 8. A gasket 10 is placed between base 7 and cap 6. A measuring conta1ner 1l preferably in the form of a common elly glass is supported onbase 7 1n an inverted position. Outwardly extend-.

' ing lugs 12 on container 11 engage angular wit flanges 13'which are rigid base 7 and 7 thereby hold container 11 firml against the base 7. A gasket 14'is arrange between the container and the base and another gasket 15 is arranged between flanges 13 and the clrcular edge 16 of the neck opening in con- 7 tamer 1. a a

The bottom '17 of glass container 11 is ground to a true'surface and drilled in three. places to provide a central orifice 19, a vent o ening 21 and aliquid: inlet 20. -A valve p ate 18 is rotatably mounted on the bottom surface 17 and .is provided with a small; square opening 22, a small opening 23 and a larger opening 24 e ual in diameter to the inlet 20. A vent tu e 25 is mounted on 85, plate 18 above and in line with opening 23.

A valve operating rod in the form of a tube 26 is arranged axially in container 11 and passes through opening 19. The upper end of tube 26 terminates in a square end 27 00 which engages the square opening 22 in valve plate 18 thereby to rotate the same. The square end 27 is threaded for a short distance to engage corresponding threads of a vent tube 28. The vent tubes 25 and 28 are braced at their upper ends by a connection 31. A washer 30 and a'spring 29 surround the square end 27 and act to press plate 18 against surface 17. a

The lower end of rod 26 is threaded at 32 to engage firmly with a tapered valve 33 r0- tatably mounted in extension 8. A liquid outlet 34 in valve 33 is arranged to discharge in a certain position into a delivery tube 35 which extends from the extension 8. An operating lever 36 is mounted at the lower end of rod 26 being held thereon rigidly by a nut 37. The'free end of lever 36 is provided with a pair of spaced depending lugs 38 for a purpose to be explained later. When lever 36 is rotated back and forth, rod 26, valves 33 and 18 and vent tubes 25,

28 rotate as a unit to alternately fill and empty container 11.

The means for releasably locking the liquid delivery control lever 36 will now be described. A cylindrical supporting block 39 is rotatably mounted at the center of the platform 5 and said block carries an operatin lever or bar 41 extending outwardly a su%cient distance beyond a leg 3 to be grasped by the hand of an operator. A 6011 sprin 40 is anchored a one end on platform 5 an after being wound for about a onefourth turn around a slot 40' in block 39 has its other end anchored thereto. The purpose of spring 40 is to maintain bar 41 against a leg or sto 3 and return said bar to that initial position after a clockwise rotation.

A coin controlled locking lever'43 is pivoted on a standard 44 and a depending lug 45 is formed on one end of lever 43 of sutlicient weight to rotate the lever clockwise to a horizontal position until said lug contacts the platform 5. In this position, a detent 46 on lever 43 engages bar 41 to lock the same from clockwise rotation. A coin tray 48 on the free end of lever 43 is adapted to receive a coin from the usual coin chute 49. A coin stop ing plate 48 is mounted on block 39 and in one position lies close to tray 48. A coin deposited in tray 48 is sufficient to overbalance lever 43 and cause a counter-clockwise rotation until the rear end of lever 43 is raised far enough upwardly to strike a vane 42 extending laterally from the operating bar 41. In this position, lever 43 has not rotated sufficiently to dro the coin from tray 48 but has rotate far enough to unlock bar 41.

It will be noted that the pair of lugs 38 depending from lever 36 are positioned to straddle the bar 41. Hence, as best seen in Figs. 1 and 2, when bar 41 is rotated clockwise from its unlocked position it will cause a similar rotation of lever 36 and its connected valves to permit of liquid delivery to outlet tube 35. When bar 41 has moved with its integral vane 42 a sufiicient distance to permit said vane to clear from locking lever 43, said lever will be permitted to rotate counter-clockwise far enough to allow the coin in tray 48 to slide therefrom and into a suitable receptacle.

In the operation of the device, during the time that ar 41 is locked the openings 24 and 20 in the valve plate 18 and bottom 17 respectively are in registration and the container 11 is filled with liquid from the main reservoir 1 and, during this fillin act, air from container 11 is vented throug o ening 21 in bottom 17 which registers wit vent tube 25.

A suitable coin deposited in chute 49 and falling in tray 48 will rotate locking lever 43 counter-clockwise until stopped by vane 42 in which position bar 41 is unlocked. The outer end of bar 41 may be asped by the operatorand rotated. forwar ly during which time lever 36 and rod 26 rotate to shift valve plate 18 into such a position that vent tube 25 will register with the opening 20 in the bottom 17 of container 11 at which time the outlet 34 in lower valve 33 will open into tube 35 to permit delivery of the liquid contents of container 11.

lVhile liquid is flowing from container 11 to completely empty the same, air flows into container 11 from vent tube 25 and an equal amount of air is permitted to flow into reservoir 1 through the hollow rods 26 and 28. Upon release of the handle 4], spring 40 will cause an opposite rotation of all of the parts mentioned that have been shifted to operate valve plate 18. Bar 41 is returned to its initial position against leg 3 and is again locked by detent 46. 4
