FREEZING APPARATUS.
Application filed January 28, 1926.
My present invention pertains to apparatus for freezing cream and other substance; and it contemplates the provision of a simple, highly efficient and inexpensive freezing apparatus, as hereinafter described and definitely claimed.
In the accompanying drawing, forming part of this specification The figure is a view partly in section and partly in elevation, and illustrative of the best practical embodiment of my invention of which 1 am cognizant.
Among other elements my novel freezing apparatus comprises a casing body 1, of any appropriate character, open at its upper end, and chambered at its lower end as designated by 2, and provided with a closure plate 3 for the chamber 2 and also provided with a drain 4, the latter being designed to discharge into a receptacle placed below the casing body 1 or to be connected with a conduit, not shown, that may lead to any desired point of discharge.
Located in the chamber 2 is'a worm gear 5 fixed to a shaft 6, stepped at 7 in a bearing carried by the closure plate 3 and extending through and adapted to turn about its axis in a bearing in the top wall of the chamber 2 and terminating at its upper end in an angular portion 8. Also located in the chamber 2 is a worm 9 on the armature shaft 10 of an electric motor 11. the latter being located exteriorly of the casing body and alongside the same.
At 12 is a can for receiving substance to be frozen. The said can in the operation of my novel apparatus is rotated about its axis, and it will be noted that the upper end of the can 12 is open, and that the can is capped by a removable cover 13 having a collar 14 journaled in the removable cover 15 of the casing. Surrounding the upper portion of the can 12 and removably arranged on supporting lugs 15 in the casing body 1 is an annulus 16. The said annulus 16 is made removable in order that when necessary access may be gained to the space within the casing body 1 and between the side wall or walls of said casing body and the can 12.
At its lower end the casing body 1 receives in the upper wall of the chamber 2 a bearing 17. The said bearing 17 surrounds the shaft 6, and is provided at its lower end with a flange 18 adapted to hold the worm gear 5 with attached shaft 6 against upward movement. At its lower end the can Serial No. 84,359.
12 is provided with a portion 19 of angular form in horizontal section which receives the angular end 8 of the shaft 6 so as to assure turning of the can 12 about its axis with the shaft 6. The exterior of the portion 19 of the can 12 is circular in horizontal section and is disposed in a shallow socket 20 at the lower end of a stationary or non-rotatable dasher 21, the said dasher 21 being of any construction compatible with the purpose of my invention, and being provided at its upper end with an angular portion 22 keyed in the casing cover 15 whereby the dasher 21 is held against rotation irrespective of the powerful turning of the can 12 about the dasher. Manifestly following removal of the cover 15 of the casing, the cap 13 of the can may be readily lifted from the can and from the dasher to afford convenient access to the substance in the can.
Coiled about the can 12 is a refrigerant conduit 30, the inlet terminal of which is designated by 31 and the outlet terminal by 32. In said conduit is located a valve 33 having a handle 34, and also in the conduit is located an expansion valve 35, said expansion valve 35 being of conventional or other appropriate construction. The valve 33 which is of cut 011' type and the expansion valve 35 are preferably arranged as illus trated relative to the casing body 1. I would also have it understood that I employ at 40 an automatic motor switch a member 41 of which is opposed to the handle 34 of the cut off valve 33. Between the switch 40 and the motor 11 is a lead 50, and also connected to the switch 40 is a lead adapted to be connected with any appropriate source of electric energy.
In the practical useh of my novel apparatus, appropriate mixture is poured in the can 12, and the dasher 21 is placed in posi tion, after which the cover 13 is placed in closed position, and cover 15 is also placed in closed position so as to receive and support the collar 14 on the can cap and prevent lateral deflection of the can. It will also be noted that on the placing of the cover 15 in the position illustrated, the cover will cooperate with the square upper end of the dasher 21 to strongly hold said dasher against rotation. The motor switch 40 is now closed through the medium of the handle 41, and the said movement of the handle 41 by acting against the handle 34 of the cut off valve 33 turns refrigerant into the expansion valve 35 and the conduit 30 about the can 12. The maintenance of the switch 40 in closed state will be attended by operation of the motor 11, and from the said motor 11 the can 12 will be powerfully turned about its axis. Incident to this operation, the contents of the can 12 will be agitated, and as freezing progresses, due to the action of the expanding refrigerant in the conduit 30. and as the contents of the can 12 become hard and stiff, the load on the motor 11 will be increased. The said increase of load on the motor 11 causes more current to flow through the automatic C11- cuit breaking switch 40 until at a predetermined time, the handle 41 flies open and brings about stoppage of the motor 11, and in said movement the handle 41 acts against the handle 34 of the valve 33 and thereby cuts off the supply of refrigerant to the conduit 30, or if preferred, the handles 41 and 34 may be so relatively arranged that the said automatic movement of the handle 41 may take place without acting against the handle 34 to close the valve 33, so that after operation of the motor 11 refrigerant may still be supplied to the conduit 30 to maintain the contents of the can 12 in a frozen state.
Of course, when the can 12 is empty, the valve handle 34 is manipulated manually to cut off the supply of refrigerant from the conduit 30.
Manifestly the annulus supported in the casing body 1 and about the upper portion of the can 12 will operate to prevent canting of the can 12 against the convolutions of the conduit 80, and will also 0 erate to prevent the fall of substance to e frozen into the space between the wall of the casing body 1 and the can 12.
Notwithstanding the practical advantages ascribed to my novel freezing apparatus, it will be noted that the apparatus is simple and inexpensive in construction and when employed in a household may be operated as an adjunct to refrigerators in which a refrigerant of expanding character is employed.
I have specifically described the preferred embodiment of my invention in order to impart a full, clear and exact understanding of the said embodiment. I do not desire, however, to be understood as confining myself to the structure illustrated and described in detail, my invention being defined by my appended claims within the scope of which structural changes and changes in arrangement may be made without departure from my invention.
