Patented Get. 29, 1929 PATENT OFFICE ARTHUR N. GULLICKSON,

OF CUSHING, Wl'SCONSN CREAM-COOLNG DEVICE Application led .Tune 15,

This invention relates to a cooling device and more particularly to a cream cooling device, and has for its primary object the construction of a device that may be conveniently positioned relative to the direction of travel of cream from a separator so that the cream will be forced to travel in a film formation around the device to provide a maximum cooling action in its flow toward the container therefor.

Another object of the invention is the novel construction and arrangement of the component parts so that a cooling fluid will travel a considerable distance before discharging thereby producing a maximum cooling effect.

Another object of the invention is the novel construction of fluid conveying means arranged in a predetermined position relative to a plurality of dist ibuting fins so that the flowing fluids will have a relative travel to facilitate the transfer of heat.

Besides the above my invention is distinguished in the novel manner of constructing and assembling the major part of the invention so that they will be connected together as a unit for insertion and removal from the receiver.

A feature of the invention is the novel manner of positioning and arranging the distributing fins so that cream or other fluid body will be made to travel over approximately the entire outer surface of the receiver.

l ith these and other objects in view my invention will be better understood from the following details of description taken in connection with the accompanying drawings, wherein:

Figure l is a side elevation of the device,

Figure 2 is a vertical sectional view on the line 2 2 of Figure l,

Figure 3 is a horizontal sectional view on the line 3 3 of Figure l.

Referring' to the drawing illustrating one of the many constructions of my invention the numeral l designates a receiver which may be of any suitable configuration but illustrated as of cylindrical formation and provided with an open top closed by the closure plate 2. Arranged wit-hm the re- 1927. Serial No. 199,083.

ceiver l is a device 3 for directing the cooling fluid from the top to the bottom of the receiver and then from the bottom to the top of the receiver, the device consisting of an inner tubular casing 4 suspended from the closure plate and terminating in a nipple 5. This inner casing l has concentrically arranged therearound but spaced therefrom a cylindrical casing G providing a dead air space 7 to insulate the cooling fluid passing through the casing fl until such time as the cooling fluid escapes from the tubular casing contiguous to the bottom of the receiver. Referring to Figure 2 of the drawings it will be noted that the casings et and 6 are substantially the same length and terminate in close relation to the bottom 8 of the receiver so that the cooling fluid will have to travel approximately twice the length of the receiver before discharging.

To extend the length of travel of the cooling fluid from the bottom to the top of the receiver I extend around the casing 6 and in contact with the inner wall of the receiver a spiral blade or vane 9 that extends from the bottom to the top of the receiver so as to give a spiral flow to the cooling fluid when travelling from the bottom to the top of the receiver. This action prolongs the period of contact between the fluid and the inner surface of the receiver to prolong the cooling action of the fluid. The closure plate 2 is further provided with a nipple l0 connected to the outlet pipe ll with an inlet pipe l2 connected to the nipple 5.

As the receiver l assumes a vertical position I have found it is of considerable advantage to discharge the fluid at the top of the receiver allowing gravitational action of the fluid to distribute the same over the surface of the receiver and to accomplish this desired effect in the best manner possible I at the point of contact of the fluid with the receiver a plurality of divergently arranged distributing fins 13 of the required formation to cause the fluid to flow along the fins to be properly distributed over the surface of the receiver in leaving the fins. As the combined gravitational action and the consistency of the cream provides a thin lm of fluid travelling over the exterior surface of the receiver it will be appreciated that the transmission of heat from the cream to the cooling fluid to the conductivity of the receiver is facilitated.

In the use of the invention I provide a bail 14 secured to the receiver and terminating in a hook 15 for suspending the device and mounted on the bail is a handle 16 for facilitating the carrying of the device. A

From the foregoing description taken in connection with the accompanying drawings it will be appreciated that I provide a device in which the parts are so constructed that the maximum cooling effect is accomplished, and as the various component partsv may be con- Structed and arranged in other relation than illustrated I wish it to be understood that I do not desire to be limited in any manner except as set forth in the following claims.

What I claim as new is:

1. A cream cooling device comprising a cylindrical receiver, a closure plate therefor, means centrally suspended by the cover plate and including` an inner casing terminating in a nipple exteriorly of the closure plate, and an outer casing arranged concentrically of the first casing but spaced therefrom, said casings extending into close proximity to the bottom of the receiver' and means for conveyingva cooling fluid to the inner casing and from the said receiver.

2. A cream cooling device comprising a vertical receiver, a closure plate therefor7 a tubular casing extending into close proximity to the bottom of the receiver-and having a nipple projecting from said closure plate, a cylindrical casing arranged concentrically of but spaced from said tubular casing, a spiral blade secured to said cylindrical casing and contacting with the inner surface of said receiver, an inlet pipe communicating with said nipple and an outlet pipe communicating with the upper portion of the receiver.

3. A cream cooling device comprising a vertical receiver, a closure plate therefor', a tubular casing extending into close proximity to the bottom of the receiver and having` aV nipple projecting from said closure plate, a cylindrical casing arranged concentrically of but spaced from said tubular casing, a spiral blade secured to said cylindrical casing and c contacting with the inner surface of said receiver, an inlet pipe communicating with said nipple and an outlet pipe communicating with the upper portion of the receiver, said tubular casing, cylindrical casing and pipes connected to said closure plate as a unit.

4. A cream cooling device comprising a vertical receiver, a closure plate therefor, a tubular casing extending into close proximity to the bottom of the receiver and having a nipple projecting from said closure plate, a cylindrical casing arranged concentrically of but spaced from sai-d tubular casing, a spiralV ceiver.

5. A cream cooling v device comprising a casing closed at its ends and having an inlet and out-let at its upper end, a tube arranged axially within the casing and having its upper end communicating with the inlet to convey cooling fluid to the lower end of the casing anda spiral vane surrounding the tube and adapted to convey the cooling Huid from the lower end of the casing to the outlet.

In testimony whereof I aflix my signature.
