DISPENSING APPARATUS.

Continuation of application Seria1.No. 551,301, filed April 10, 1922. This applicationfiled March 8,1923.

Serial No. 623,746. i

To all whom it may concern:

Be itknown that we, JOSEPH A. GOYER and LYNN T. Lnn'r, subjects ofjthe King of Great Britain, residing at Montreal, Province of Quebec, Canada, have invented certainand new useful Improvements in Dispensing Apparatus; and we do herebydeclare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a new and. useful dispensing apparatus designed especially for use in connection with a watercooler, and is a continuation of our Unitedstates application Serial No; 551,301, filed April 10th, 1922. The general principles underlying the invention are also applicable to a dispenser for heavy fluids, such as syrups and the like. f

In using a cooler of the inverted bottle type, the mouth of the. bottle, in all operations of filling, crating, and handling in transportation, comes in contact with the hands of the persons performing these operations. When a bottleis finally inverted in the cooler, the mouth which has comein contact with numerous hands is submerged in the water to be consumed. One of the objects of the invention is to avoid such unsanitary conditions.

The invention operates on the principle of the siphon, andincludes novel and efiicient means for starting the'flow of fluid.

For the purpose of illustration, a set of drawings is herewith attached, of which Figure 1 is a vertical section therethrough;

Figure 2 is a vertical section of the siphon starting device;

Figure 3 is a section on the line 44 of Figure 2;

Figure 4 is a section on the line 55 of Figure 3;

Figure 5 is a vertical section of the upper portion of a modification;

Figure 6 is a detail of Figures 1 and 6; and

Figures 7, 8 and 9 are details of the compressor in different stages of operation.

In the above views in which like reference characters are employed to designate corresponding parts throughout, the stand consists of a plurality of legs 11 upon which is mounted a top or platform 12. A shelf 13 is secured tothe legs beneath the platform and supports a cooling device 14. A

fluid container 17 of the type in which distilled water is supplied is mounted on" the platform '12 and is closed by a stopper '18.

A siphon tube 19 passes from the bottom of i the container through the'stopperandcommunicates with the cooling chamber in. a

manner described below. An air passage or vent 20 is formed in the stopper for the purpose of avoiding the creation of a vacuum in the receptacle. This vent consists preferably of' a curved tube 21 inserted in :the passage, provided :with an air filter '22 which may consist of any material through which aircan pass and which. will,,notallowthe passage of dust particles. 7

One of the legs 11 terminates below the platform 12 and is provided at its upper v end With a plug 23. Aunion 24' is secured to thisend andreceives an upwardly extend ing pipe 25in which the lower .endo'f a siphon leg 19' is fitted by means of a screw nipple 26 and porousor permeable packing 27. A valve28 is fitted in the pipe 25 for permanentlyshutting off the water supply.

The cooling device heretofore referred to comprisesa pair of. vessels' '29 and 30. one Withinthe other. A. 'ring31 overlies the tops of the vessels, while a cover 32'is seated in'the ring, The cover is co-eXtensiveIwith the cross sectional area of the vessel 30so that ice may be, uniformly distributed withins'aidv vessel, thus overcoming the disadvantages of the usual fillingopenings. The space between the inner walls of thesevessels is filled with a heat insulator 33 such as granulated cork. Within the inner vessel is a cooling tank 34 having a cover 35. A nipple 36 communicates with the interior of the tank and is connected tothe union 24 by means of an elbow 37 and a nipple 38.

A water tight fit is obtained by washers 39 screwed against the elbow and the wall of, the vessel 30 by means of nuts 40. The lower portion of the tank isprovided with a pipe 41 which passes through the insulated wall to a tap 42. A leak proof'ar: rangement is here provided by means of the washers 43 and nuts 44. A drain pipe 45 is providedwith the base of the cooler and allows the melted ice to drip on to a drip plate 46 disposed beneath the tap 42 and pipe 45, and inclined towards the bucket 16. 7

It will be seen by reference to Figures 1 to t that the siphon tube 19 is joined to the leg member 19" by means of a union e7 from which extends a stem 49 in an upwarddirection. The free end of the stem is formed in the nature of a piston 50 and is surrounded by a tightly fitting slidable Cylinder 51 having a closed top 52 and an air vent 53 in its bottom. Between the leg 19 and the union is fitted a valve casing 54; having an intermediate restricted portion 55 one side of which is curved to form a valve seat 56. The end of the casing adjacent the valve seat is formed with a pair of inwardly turned fingers 57 adapted to retain the valve head 58 which is of such configuration as to close the restricted portion 55 when in proper position. This valve is normally open, the valve head being spaced from the seat by gravity. A- similar device 59 is provided between the pipe 19 and the union 47, and opens in the direction of the union.

When it is desired to start the flow of liquid, the cylinder 51 is pulled upwardly to create a suction above the piston 50. This suction'draws from the container 17 through the pipe 19 and stem L9, at the same time opening the valve 59. The liquid thus drawn and dropping from the union 4&7 passes the open valve 58 and flows through the pipe 25 and cooler. Once the flow is thus started, it continues by reason of the atmospheric pressure upon the surface of the fluid through the vent 20. The air displaced from the cooling tank 34 during the filling of the latter passes upwardly through the nipple 36,.

elbow 87, ipe 25 and out of the permeable packing 2 It will therefore be seen that the pipe 25 serves the double function of conveying water from the siphon to the cooling chamber and allowing the air displaced from the cooling chamber to find its way to the atmosphere.

In the modification shown in Figures 5 to 9, a compressor bulb 71 having two open ends is disposed betweenthe siphon legs 19 and'19 having its ends in communication 73 being closed by the same action (Figure 9). After the suction in the bulb has been released by the complete expansion thereof, and filled with water, the weight of the latter pushes the lower valve 73 open, and a continuous flow is had therethrough by reason of the atmospheric pressure upon the surface ofthe liquid in the vessel through the vent 20. The upper valve .72'remains open because of the downward flow of water thereon.

Having thus fully described the invention, what we claim as new and desire to protect by Letters Patent is i A device for dispensing liquid comprising a lower vessel and an upper vessel having an air vent in its top, a pipe extending upward ly from said lower vessel to substantially the top of the upper vessel, a siphon tube extending from the lower portion of the upper vessel through the top thereof and having its lower leg received within said pipe, a permeable packing between the leg and the upper end of said pipe, and means communicating with said siphon for reducing the pressure in the upper leg thereof.

In witness whereof we have hereunto set our hands.
