Patented Dec. 9, 1930 PATENT FICE ERIC K. SKONBERG, or BROOKLYN, NEW YORK, ASSIGNOR T TiiERM o-MAT DIS- rnnsnn, me, A CORPORATION or new YORK LIQUID DISPENSING DEVICE Application filed ma 26,

My invention relates to an apparatus for dispensing liquids and, more particularly, to a coin-controlled dispensing device, although certain features of the invention are applicable to vending machines for other purposes. In apparatus 3 of the class described, the prior art devices are of a complicated nature comprising an undue multiplicity of parts and from a manufacturingstandpoint, are not only expensive to construct, but also expensive to maintain.

It is an object of my invention, therefore, to provide a liquid dispenser which comprises a minimum number of parts and which is economical to manufacture and'install, as well as to maintain at a relatively low cost.

Another object is to provide in a liquid dispenser a novel combination of valves and air vents whereby measured quantities of aliq- 0 uid may be delivered in a short time from a main reservoir.

A further object of my inventionis to pro? vide a simple and novel coin control for a dispenser. a V Other objects will appear from the detailed description'which follows.

In the drawings:

Figure 5 is a top plan View of the coin-controlled mechanism; and V Figure 6 is a cross sectional view on's'ec't'ion 4c 6-6 of Figure 5.

Referring to the drawing in detail, my improved dispensing device: comprises a casing 1, which includes an upper portion 2, a lower 7 portion 3,-and a base 41. A shelf 5 is arranged 4 to support a cup 6 in position below a fluid delivery spout 7. The shelf is extended to a point adjacent the delivery orifice 8 of a chute 9 whereby to'receive a lump of sugar delivered from the chute at each operation'of the device. An operating rod 10 and a coin slot 1930. Serial misuse.

11 are arranged in convenient positions adjacent the spout 7.

A transverse partition 12 serves to support a fluid reservoir 13 within the casing portion 2 in position above a coin-controlled 55 dispensing mechanism located within the lower casing portion 3. I- prefer to employ a reservoir of the thermos type formed by the usual inner. and outer shells 14, 15. The reservoir is supported in an invertedposition with its neck or cap portion 16 extending through an opening 17 provided in the partition. V a

A ring 18having a flange 19 and a threaded extension 20 is adapted to screw upon the threaded portion of the neck 16. A plate or base 21. is supported in position upon the flange 19, which plate'in turn supports a liquid measuring container 22. A gasket 23 is arranged in position between the end of the neck '16- and a flange 24 formed on the container 22; This arrangement permits the container 22, gasket 23, and plate 21 to be forced against the end of the neck 16 by rotation of the ring 18 and extension 20 upon the neck. 1

A combined valve and valve operating tube 25 is rotatably mounted centrally withinthe container 22. This tube is shown in detail in Figurej l and comprises essentially a tubular portion 26 and a valve portion 27. The portion 27 has the shape of an inverted truncated cone and is provided with a fluid outlet port 28' and an air inlet port 29, and, as shown in Figure 2, seats within a similarly" shaped extension 30 formed on the plate 21. An air outlet port 31 is provided 1 at the, extreme upper end of the tube 25 and the tube is provided at its opposite ends with threaded extensions 32,33 and 3A, the purpose "so of which will be described later. a

Referring to Figure 2, the upper-end'o the'tube 25 is rotatably mounted in anopening formed centrally in the-top of the con tainer. A nut'35 engagesthe threaded per-e tion 33 and serves to maintain the valve portion 27 within the extension 30. A valve operatingpinion 36 is threaded upon the extension 34: and locked thereto by the pins 37. A valve 38 is rotatably mounted onthe container 22 and is locked in position on the tube 25 by means of a washer 39 and anut 40 whichengage the extension 32.. The valve.

38 is provided with fluid inletports 41 which register in an open position of the valve with ports 42 formed in the container 22.. An outlet port 43 for fluid and an'air inlet port 44 are formed in the extension to the plate2l. It will be noted from Figure 2 that the parts are in position to permit the delivery of the fluid. The valve 38 has closed the inlet portsliquid from the reservoir 13.. Itwill-be noted when port 43 is openthat air inlet port 44 is open. to permit airto fiow through ports 44,. 29 and 31 in succession, to vent air into a the container 22, whereas when ports 43; and

. 44 are closed, the airinthe container 22 will be vented through the ports 42 into-the reservoir 13, thereby permitting liquid to. flow from. the reservoir toithe container 22.. This arrangement of valves and. ports provides a very simple, compact and eflicient arrange:- ment whereby to insure a quick passage of liquid to and from the measuring, container and a simultaneous venting of air fromiand to the container; and reservoir.

The operating mechanism: and coincontrol I for the dispenser will now be described. As shown in detail in Figure 5, the operating rod- 10 is connected to a slidebar 45, which in. turn; is mounted to slide in a. support or guide 46. The guide 46 is carried byte support 47 suitably mounted on the bottom plate 4 by means of posts 48-. The; support 47 is provided with a bearing; 49 whichreceives a thrust bearing; 50- that engages the lower end of the tube A spring is fixed at one end 52 to the guide 46' and at its other end 53 toalug 54 formed on: the bar 45. A rack bar 55 is mounted ontheslide bar 45 and engages the pinion 36. An extension 56 onone end of the rackbar 55'slidingly' engages abearing 57. A coin slot 58 is formed partly in rack 55 and partly inrbar 45,'whereby the, present-sofa coin in: this slot will'lock 7 A plate-59 atlixed to the rack and bar together to cause them to slide as a unit. a jlug 60 extends laterally from bar 45. V

the bar 45 serves to maintainthe-rack 55 in position on the bar 45. A slot 60' is formed.- in-the bar 45 at a suitable locationfer the, purpose of permit- :ting the coin to drop from and below the slot 58-xto unlock the raekffr om} the bar at the proper point. ottheir joint; travel; ,A coin chute 61 extends from the-coin. slot 11 to a position adjacent the slot 58. A bell crank pusher lever 62 is pivoted at 63 to a fixed support. The free end of the pusher is adapted to engage the lowermost lump of sugar in the chute 9. A pin 64 projecting from rack 55 is adapted to engagelever 62 to rotate the? latter clockwise while'a. spring 65 functions to restore the lever 62. A register 66 is operably associated by means of link 6*Zand l'ever 68-with the-lever- 62 to tota l ize the'operati ons of the device.

In the operation of my apparatus, a coin inserted in the slot 11 will roll by gravity along; the chute 61 and lodge itself in the slot 581 A forward pull on the rod 10 will causethe slide 45 and. rack bar 55- tomove as a unit'since these two members arelocked together by-the coin. The: pinion 36 being in mesh with the rack. bar 55. will be rotated together. with the" valve tube 26 whereby toclose the outlet port 43 andv open the inlet ports 42,. and the container 22 will be. quickly filled with liquid from. the reservoir 13,.

. The forward movement. of the bar 55 will cause the pin. 64 o strike thezlever 62, thereby rotating the latter clockwise and causing a lump ofj'sugar to discharge from the chute 9.

Rotation of the lever 62fwill operate'the. Link 67 and crank 68 to move the. register 66; one step. Theforward movement of the rod. 10 is limited by a: stop? 69 adj ustably mounted on the rod. When the rod 10- has reached its extreme -forward. position, the coin. in slot 58 will :ta-ll. by gravity through. the slot. 60.

.The operator is required to. return. the rod. 1-0

in order to receive a measured. quantity of liquid.

Whentherod 10 is pushedbaek, the lug :6:Q- on the slide 45 will engage the rack 55 and returnthe latter to, its original position,

thereby rotating the pinion 36 and tube 26 in the counter-clockwise direction, whereupon the outlet port 43 isopened andthe in let ports 42 are closed. At the same. time,,the inlet air port 44 is opened to permit, air to flow upwardly through the tube 26 and out through air. port 31. into the container 22, whereby the contents.- of-thecontainer will be permitted to flow through thespout 7 into the-cup 6; t r I claim as my invention 1-..
