Application October 25, 1950, Serial No. 192,057

This invention relates to liquid mixing apparatus and particularly to apparatus for intermixing predetermined volumes of two or more liquids.

Soft drink concentrated syrups are prepared with sumcient sugar content to prevent fermentation thereof. However, when thi syrup is diluted before carbonating the drink, it will spoil in a relatively short time. Therefore, it is necessary to mix only small portions of the liquid to be carbonated to prevent wastage from spoiling of the diluted concentrate.

It is an object of my invention to provide apparatus constructed to mix predetermined volumes of two or more liquids by an automatically controlled mechanism.

It is another object to provide mechanism for mixing a batch of liquid produced by intermixing predetermined volumes of two or more liquids through a single cycle of operation.

More specifically, it is an object to provide two or more liquid supply tanks, each having a liquid delivering bucket, normally positioned therein and adapted to be shifted from filling position to dumping position to discharge liquid from the bucket into a single mixing compartment.

It is still another object to provide a number of liquid carrying buckets in the form of elongated troughs, each being closed at one end, and mounted on a single shaft to be swung upwardly from filling position to dumping position and thereafter returned to filling position, a single revolution power source being provided for actuation of a pitman to oscillate said bucket on the shaft and operate the mechanism through a single cycle of operation.

These and other objects and advantages will more fully appear from the following description made in connection with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views and in which:

Fig. 1 is a side elevational view of my mixing apparatus with a portion of the wall broken away and showing the mixing buckets in filling position by full lines and in dumping position by dotted lines.

Fig. 2 is a top plan view of the structure shown in Fig. 1.

Fig. 3 is a transverse vertical sectional view taken substantially along the line 33 of Fig. 2.

Fig. 4 is an elevational view showing the single revolution motor and the pitman actuated therey;

Fig. 5 is a diagrammatic view of the electric 2 Claims. (Cl. 222-56) 2 wiring circuit for the apparatus illustrated; and

Fig. 6 is a fragmentary traverse sectional view taken substantially along the line 8-6 of Fig. 4.

As shown in the accompanying drawings, I provide a compartmented liquid confining tank 8 having, in the form shown, a pair of supply compartments 9 and I8 divided by a longitudinally disposed partition II terminating at a transversely disposed partition I2, which forms a mixing compartment I3. A transversely disposed pivot shaft I4 is mounted across the upper portion of the tank 8 and in the form shown, is disposed directly above the transverse partition I2. A pair of liquid carrying and delivering buckets I5 and I6 are journalled'for oscillation in side by side relationship on said shaft I4. These buckets I5 and. I6 are in the form shown, elongated troughs, which are closed at the free ends thereof, a partition I5a closing the end of the water supply trough I5 and. a partition I6a having the adjustable level controlling notch I611 closing the end of syrup supply trough I6. The two troughs I5 and I6 are rigidly interconnected by an inverted U-shaped yoke I1, and are slightly spacedto straddle the longitudinal partition II, the bucket I5 operating in water supply compartment or tank 9, and the bucket I6 operating in syrup supply compartment I0.

A source of actuating power, such as the single revolution electric motor I8 is provided, and in the form shown, is mounted ona suitable platform I9 fixed at one end of the tank 8. The

motor I8 is wired in a conventional manner, so that whenever the switch 29 has been closed to start, the motor, the same will continue to operate for a single revolution, and then will be automatically stopped. The details of this internal wiring of the motor I8 are not shown, but there are a number of such motors conventionally being produced for sale such as a model 604B6 motor made by Minneapolis Honeywell Company, Minneapolis, Minnesota, and shown generally in Patent No. 2,194,701. It should be noted that the motor disclosed in said patent must be modified to produce a 360 rotation instead of the 180 rotation produced by the circuit and limit switches illustrated in said patent. The rotary shaft of motor I8 is disposed transversely of the tank 8, and a crank arm 20 is fixed thereto. The crank arm 20 has an elongated slot 20a. formed in the outer portion thereof, as best shown in Fig. 4. An adjustment pin 22 is inserted through said slot 28a, as best shown in Fig. 6. A bushing and collar unit 2| is journalled on said bushing to be reciprocated by crank arm 20
