Application February 6, 1933, Serial No. 655,383 Renewed September 28, 1939 3 Claims.
to provide a device of the kind described with a freezing coil around the outside of the inner wall and having a solid metal contact with said wall. The invention has as a further object to provide a vertical freezer of this description. The invention has a further object to provide a freezer which shall be compact, cheap in construction and efilcient in operation. The invention has other objects which are more particularly pointed out in the accompanying description.
Referring now to the drawings, Fig. 1 is a vertical sectional view through one form of freezer embodying the invention;
Fig. 2 is an enlarged sectional view of the upper end of the device;
Fig. 3 is a sectional view taken on line 3-3 of Fig. 2;

Fig. '7 is an enlarged sectional fragmentary view showing the contact of the coil with' the receptacle;
Fig. 8 is an enlarged sectional view taken on line 8-3 of Fig. 1.
Fig. 9 is a fragmentary section showing a modifled construction.
Like numerals refer to like parts throughout the several figures.
Referring now to the drawings, I have shown a receptacle I which receives the material to be frozen. This receptacle is made of good conducting material, such as metal. Surrounding the receptacle I is a coil 2 through which the refrigerant is circulated. This coil is preferably arranged so as to have an intimate or metal con tact with the receptacle I. I prefer to have the coil tightly wound around the receptacle I, and I may then solder the coil to the receptacle I so as to make a metallic connection. This solder is shown at 3. The coil is preferably coiled about the receptacle t, a coil at a time, and soldered as it is coiled so that when the complete coil is formed it will be completely soldered to the receptacle I. I may arrange the coil so that the inlet 4 is at the bottom of the coil, the refrigerant com- 'ing in at the bottom and circulating around the receptacle I through -th`e coil and being discharged at the top thereof into the discharge pipe 5. The pipe 6 may be used as the inlet if desired, or the inletv may be arranged at any position of the coil if desired.l There is an outer. casing 6 ony the outside of the coil 2 and suitable heat insulating material 1 is provided for insulating the coil 2 and the receptacle I.
Suitable means are provided in the receptacle I for agitating the material as it is being frozen. This agitating means isY driven in any desired manner, as for example by a motor 8 which is located vertically below the receptacle I. This motor has its shaft connected to the usual gear head 9 so as to secure the desired driving speed. The shaft I0 driven by the motor is coupled to the shaft I I which drives the agitating device, by a coupling which consists of a metal member I2 connected with the shaft I0 and a metal member I3 connected with the shaft II, there being a connecting element Il between them which is made of non-metallic material such as leather. 'I'he members I2 and I3 are preferably provided with three arms I5 which do not register. The arms of the member i2 are connected to the nonmetallic member I4 by suitable connecting devices II, and the arms of the member I3 are connected to the non-metallic member I4 at different points by the connecting devices I1. It will thus be seen that there is provided an elastic connection between the motor shaft and the agitating device in the receptacle I. The shaft I I projects intothe receptacle I and is connected with a rotatable frame so as to rotate it. This frame consists of the bottom member I3 and the top member 22 connected together by the connecting member i3d. Extending between the members I8 and 22 are the shafts i9 and 20 rotatably mounted in said members. There are also Scrapers 2l rotatably mounted upon the members IB and 22.
Connected with the shaft I9 is a gear 23, and connected with the shaft 20 is a gear 24. These gears are connected together by a gear 25. The gear 25 is connected with a shaft 2B, being keyed thereon. The shaft 26 has a. non-circular end 2l which fits into a noncircular opening in the end of the member 28. The member 28 has a flange 29 which engages a shoulder 36 on the cover 3l. The member 28 has a projecting part 32 smaller in diameter than the body portion thereof which projects through a spring collar 33. This spring collar has the spring arms 3d. A handle 36 is provided with a hollow screw threaded hub 31 which surrounds the part 32 and the spring collar :tand-which engages alserew thread in the hollow upper end 88 of the cover Il.
. When the handle I4 is unscrewedor loosenedl thehhft l'nditlltmhedlwl'llfmto rotate; and hence when theahaft li is rotated theshafts Ilandllarenotrotatedthegear 2l runningaroundwiththegearsusothataaid ened this causes the spring arms 34 of the spring collar 3l, due to the inclined faces II, to be compressed so as to frictionally engage the part 32 and the hub 31 of the handle and Stop the rotation of the shaft 2l. This holds the gear 2i stationary. The rotation of the shaft Il now causes the gears 24 to rotate as they rotatelaround the stationary gear 25, and causes the shafts i! and 20 to rotate, causing the beater arms to rotate about the axis of the shafts I9 and 2l and to also move about through the material in the receptacle I.
The gears 23, 24 and 25 are provided with a housing which is water proof so that the gears will be protected from moisture. This water proof housing is clearly shown in Figs. 1 and 2, the bottom being formed by a part of the member 22 and the top by the plate 22a,l which engages the upstanding part 22h. 'I'he shafts I9 and 2li have their ends projecting into this housing through openings, which are provided with the leak proof stufllng boxes 22e. These stufllngboxes also preferably contain and support the roller bearings 22d. The receptacle l is provided with a discharge opening 38 having a cover 39. The motor is preferably provided with a casing dil. A support 4l of any suitable material is provided for receiving containers into which the material from the receptacle i is discharged through the opening 38. This support is provided with an upstanding edge 42 which fits over a supporting piece 43, a portion of the support il resting on the member 44, which may be the top of the cabinet. The support is placed in position by tilting the outer end upwardly and placing the upstanding edge 42 under the supporting piece 43, and then lowering it to .its supporting position. This support is removed in the same manner by tilting it upwardly and disconnecting the upstanding edge 42 from the holding piece 43. The position of the portion of the support receiving the receptacle will depend, of course, upon the height of the receptacle, and will be in such position topermit the receptacle. when placed on it, to receive material from the opening. il.
Instead of having the metal or soldered contact between the cous and the receptacie l, I may enclose the coil and put some liquid. such as brine.
inside the enclosure, asshown in Fig. 9, this curing high efilciency.
I claim:
1. A device for freezing liquids comprising a receptacle for the liquid, a discharge opening for said receptacle, a fixed part below said opening, an outwardly projecting supporting piece on said fixed part. a tray having an upstanding edge and adapted to be tilted to place the upstanding edge under said supporting piece so that the tray will be held in horizontal position below said discharge opening.
