REFBIGEBJATING APPARATUS.

Application filed November 1, 1921. Serial No. 512,081.

To all whom it may concern:

Be it known that I, FERNAN' O. CONILL, a citizen of the Republic of Cuba, and a resident of Marseille, France, have invented acertain new and useful Refrigerating Apparatus, of which the following is a specification.

This invention relates to refrigeration and more particularly to refrigerating apparatus.

One of the objects of thisinvention is to provide a simple and practical refrigerating apparatus of thoroughly reliable and dependable action and of a construction and form as will be readily portable. Another object is to provide a simple and practical means for reliably controlling the action of the apparatus, which apparatus may be in general of the type set forth in my co-pending application, Serial No. 496,232, filed August 29, 1921. Another object is to provide a valve mechanism for controlling the action of such apparatus, which mechanism will be of simple construction, thus lending itself to inexpensive manufacture and to ready and convenient manual control. Other objects will be in part obvious or in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangements of parts as will be exemplified in the structure to be hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawing, in which is shown one of various possible embodiments of this invention Figure 1 is a sectional view of this apparatus showing the same tilted in one direction.

Figure 2 is a similar view partly in el vation showing the same tilted. in the opposite direction.

Referring now tothe drawing and more particularly to Fig. 1, there is shown a receptacle'or container 1 adaptedto receive a suitable liquid in which is dissolved asuitable liquefiable gas. Thus, for example, the solvent may comprise water, glycerine, or a suitable heavy oil, and the gas dissolved therein may be ammonia or sulphur dioxide, for example. F or convenience of descripin the drawing. The conduit 3 has a downwardly directed branch or leg 4 connecting to the interior of the refrigerating chamber 2, the latter being provided with an interior chamber 5 preferably of tapered form as shown in the-drawing. In this chamber 5 may be placed directly the substances desired to be refrigerated or frozen but preferably the chamber 5 receives suitable molds or auxiliary containers in which the substances to be frozen are placed as is more clearly set forth in my aboveonentioned co pending application. 7 The conduit 3 has a downwardly extending branch 6. adjacent its other end whence it is formed to provide two branches 7 and 8 each communicating with the receptacle 1, the former being in communication with the receptacle 1 adjacent its upper end and the latter being extended downwardly to ward the bottom of the receptacle 1 and well below the normal level of the liquid contained therein. The connection between the'branch 6 of the conduit 3 and the branches 7 and 8 is preferably made by means of a yoke portion 6 extending transversely of the branch 6 and in a general horizontal direction. as shown in the drawing. The branches 7 and 8 are provided with valve seats 9 and 10, respectively, and preferably at'their upper ends and substantially where they join the yoke portion 6 The valve seats 9 and 10 are adaptedto coact with a valve member preferably taking the form of a hollow ball 12. The bottom portion of the connecting yoke 6 is preferably curved so as to provide portion intermediate its ends of higher level than the valve seats 9 or 10 and so that there is in effect formed a roll-way for the ball valve 12, this rollway 11 acting to guide the ball valve 12 in its transit from one valve seat to the other. Thus, referring to F ig, 1, it will be noted that when the apparatus is tilted into the position shown in Fig. 1, the ball valve 12 rides into and remains in connection with the valve seat 9. Vice versa, whenithe apparatus is tilted in the opposite direction or into the position shown in Fig. 2, the ball valve 12 rolls across the way 11 and into eoacting position with respect to the valve seat 10.

In order to insure the proper positioning of the valve 12 with respect to the valve.

seats there are provided two handles 13 and 1 1 conveniently secured to the transversely extending conduit 3, it being noted that the handles 13 and 14 are arranged. on opp0 site sides of what may be termed the center of gravity of the apparatus as a whole. By lifting the apparatus by the handle 13, the apparatus is' automatically swung into the position shown in Fig. 1 and the ball valve 12 placed in co-action with the valve seat9.

When the apparatus is grasped by the handle 14 it is automatically swung into the position shown in .Fi 2 in which it will be noted that the valve 12 is transferred to the valve'seat 10 in the branch 8 and has thus in effect opened the passage through.

gresses the gas, such as ammonia, is driven out of the solvent, such as water for ex ample, and passes through the branch 7, the branch 6, the conduit 3, the branch 4 and into therefrigeratingreceptacle 2. During this stage the receptacle 2 may be cooled. as by dousing it with, or immersing it in, water or any other suitable cooling medium, and the gas transferred as above described to the refrigerating receptacle 2 condenses and in effect liquefies. After substantially all of the gas has been driven out of the solvent in the receptacle 1 the heating of the solvent is discontinued and the apparatus is thereupon grasped by the handle 13 thereby automatically to position the parts as shown in Fig. 1.

When so positioned, the receptacle .1 may be cooled as was the receptacle 2 during the.

stage hereinabove described, and the sub stance to be frozen having been placed within the chamber 5 undergoes cooling or re frigeration. The liquefied gas collects in the lower annular space in the refrigerating "rates it obtains its heat of evaporation from the contents of the chamber 5, thus cooling the contents, and upon continued evaporation passes upwardly through the branch 4. thence througlnconduit branch 6 and branch 8 into the receptacle 1, it being noted that the ball valve 12 prevents the passage of the gas through the branch 7 which, as above noted, communicates with the upper portion of the receptacle 1. 'The gas is thus constrained to flow downwardly through the extended branch 8 and into the solvent,

whence it is reabsorbed thereby and again often as desired, it being noted that no loss of solvent or gas takes place.

It will thus be seen that there-has been provided in this invention an apparatus in which the several objects hereinabove set forth as well as many advantages are.

achieved. The construction, it will be noted,

is simple and yet thoroughly practical and reliable and thus insures proper sequential s operation of the apparatus through its va-..

rious cycles.

As many possible embodiments maybe made of the above invention and as many changes might be made in the embodiment above set forth, it is tobe understood. that all-matter hereinbefore set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
