LIQUID-DISPENSIN G APPARATUS.

To all whom it mag concern:

Be it known that we, CHARLES R. MoDoN- ALD and ALBERT E. BEVAN, citizens of the United States, residents of xlTPOIl, county of Summit, and State of Ohio, have invented new and useful Improvements in Liquid- Dispensing Apparatus, of which the following is a specification, the principle of the invention being herein explained, and the best mode in which we have contemplated applying that principle so as to distinguish it from other inventions.

Our invention relates to liquid-dispensing apparatus and particularly to apparatus of this character designed for the dispensing of soft drinks, cream for coffee, etc., in restaurants, soft drink parlors, etc., carrying on a retail trade; also, for the dispensing of syrups at soda fountains. The objects of the invention are to provide apparatus of this character which may be economically built, easily and accurately operated, which shall dispense at each operation substantially the same amount of liquid, in which the liquid may be kept cool and refreshing, and which shall be satisfactorily sanitary.

The annexed drawings and the following description set forth in detail certain means embodying our invention, such means constituting, however, but one of the various forms in which the principle of the invention may be applied.

In said annexed drawings:

Figure 1 represents a vertical cross-section of our dispenser, taken in the plane indicated by the line II, Figure 3;

Figure 2 represents a fragmentary vertical section, taken in the plane indicated by the line 11-11, Figure 1; v

Referring to the annexed drawings in which the same ordinals indicate the same respective elements in the several views, I indicates a main casing by the ordinal 1, having a cover 2 formed with doors 3 through which ice may be dumped to retain cool the liquid contents of a receptacle 4 which is mounted upon posts 4 in the casing 1 and formed with a filling opening covered by a door 5, all as plainly indicated in F igure 1. This liquid receptacle 4 is formed with a well 6, the same in the form of apparatus illustrated, being aseparate cylindrical receptacle mounted by means of the flange 6 upon the floor of the main receptac184 and being in vertical alignment with a a lateral, vertically-extending channel portion 4 formed in the receptacle 4, as plainly shown in Figures 1 and 4:. However, we do not lay any stressupon the particular connection of the well 6with the receptacle 4 or the formation of the channel 4 or even whether or not the receptacle 4 and well 6 are integral or separate members. The receptacle 4 is supported so as certainly to drain into the well 6 so that it is evident, if there is any liquid in the receptacle 4, the well 6 will receive the same and it is the design of the apparatus to dip this liquid accurately and cleanly in measured amounts from this well 6 and dump the same into any desired receptacle exteriorly of the casing 1. This dipping is done through the medium of a bucket 7 adapted to be raised and lowered through the medium of a vertically reciprocable rod 8 having a finger piece 9. The discharge of the measured liquid is effected through the casing opening 10 normally covered, except at discharge periods,

Ill)

by means of a door 11 pivoted at one edge upon a horizontal axis 11. This casing opening 10 is in reality formed in an upwardly projecting cover member 12 formed with a vertical extension 13 serving as a bearing surface for the reciprocation of the rod 8, all as plainly shown in Figure 1. This member 13 also serves as a support to which is attached the hinge 14 of the door 11. The bucket7 is secured to the lower end of the rod 8 by means of a yoke 15 having arms 15 in the lower end of which trunnions 16, provided upon or formed integrally with the bucket 7 are pivoted. The bucket 7 is so weighted and pivotally hung as normally to maintain the position shown in Figure 1. It is evident that this position will enable the bucketwhen pulled upwardly by the rod 9 to dip an accurate measured amount of the liquid in the well 6. Secured to the outer wall of the bucket 7: is a lug 17 having an inclined groove 18, this groove 18 being bounded upon both sides by walls 18, one of which is partially cut away at its upper side so that a pin 19 projecting inwardly from the casing member 12, as plainly shown in Figures 1 and 5, will pass through the opening 18 and intersect the other wall 18, when the bucket 7 is raised, as shown in Figure 5, thus causing the bucket 7 to swing upon the trunnions 16, thus discharging the contents of the same through the opening 10, the mouth 20 of the bucket 7 being of a formation as plainly shown to effect such discharge in a very satisfactory manner. Before this discharge actually takes place and substantially concurrently with the tipping of the bucket 7, the door 11 has been opened in the following manner: Pivoted in the oppositely disposed walls of the casing member 12 by means of its arms 22 is a yokeshaped wire frame 21, plainly shown in Figure 1, in the position which the same occupies, when the bucket 7 is in its lower position. As the bucket 7 is raised by the rod 8 the yoke 15 intersects the arms 22 of the frame 21 and swings the latter outwardly upon its pivoted ends to the position shown in Figure 5, this movement of the frame 21 causing the same to pass through the opening 10 which will result in said frame 21 raising the door ll to the position shown in Figure 5, as will be readily understood. When the fingerv piece 9 is released or when the bucket 7 is positively lowered by means of pressing down said finger piece 9, the weight of the door 11 will force the frame 21 back into the position shown in Figure 1, thus both closing the discharge opening 10 and putting the frame 21 into position for again opening the door 11 when the bucket 7 is again next raised.

In order more accurately to disclose how the lug 17 and the pin 19 realign the bucket upon its downward movement to quickly tilt the same into its normal position, reference is made to Figures 8 to 12, inclusive. It will be noted that the bucket drops or is pushed from the dumping position shown in Figure 5 to the position shown in Figure 8 and that then the pin 19 intercepts the upper wall 18 and, acting thereon and traveling in the groove 18, swings the bucket, as the latter is lowered, first into the position shown in Figure 10 and then into the position shown in Figure 11. It is not meant that the realigning ofthe bucket is effected in a jerky manner but simply that Figures 10 and 11 1 illustrate two positions of the bucket as it is being continuously tilted from the position shown in Figure 8 to the position shown in Figure 11.

The discharge from the bucket 7 is so complete, and the tilting of the same again into its normal position so quickly effected, i. e., from the position shown in Figure 5, to its normal upright position, that there is practically no drip of the liquid from the mouth ing in retail quantities of any liquid and we claim it for such general purposes, but we have particularly designed the same for the keeping and dispensing of cream for coffee, as also soft drinks, and syrups for sodas, in retail'quantities.

What we claim is: z

1. In liquid-dispensing apparatus, the combination of a liquid receptacle formed with a downwardly-extended well compartment; a bucket; means for raising and lowering the latter from and into said well, the receptacle being formed with a discharge opening; a pivotally-mounted cover for said opening; a pivoted frame controlled by the bucket movements for opening said cover, the latter being free to close under the force of gravity and adapted when closing to move said frame back to normal position; a lug attached to said bucket and formed with an inclined groove; and a pin fixed in the wall of said receptacle adjacent said cover in the line of movement of said lug and adapted to engage the walls of said groove to tilt the bucket upon its upward movement and to realign the bucket upon its downward movement.
