TION OF ILLINOIS.

OF CHICAGO, ILLINOIS, A CORPORA- PASTEURIZER AND RIPENEB.

Specification of Letters Patent.

Patented July 3, 1917.

Application filed April 12, 1915. Serial No 20,870.

To all whom itmay concern:

Be it known that I, THEODORE L. Venn runs, a citizenofthe United States, residing at Fort Atkinson, in the county of Jefferson and State of VVisconsin, have invented certain new and useful Improvements in Pasteurizers and Ripeners, of which the following is a specification".

This invention relates to apparatus for ripening cream and for pasteurizing milk and cream.

The object of the invention is to improve the construction of apparatus of this class with a view to increased efiiciency and simplicity.

In the accompanying drawings, Figure 1 is a longitudinal vertical central sectional view through an apparatus embodying the features of my invention. Fig. 2 is a sectional view of an air intake valve. Figs. 3'

and 3 are sectional views of members used in an alternative construction. Fig. 4: is an end elevation of the apparatus, looking from the left-hand end of Fig. 1. Fig. 5 is a fragmental view. Fig. 6 is a plan view of the parts shown in Fig. 4. Fig. 7 is a sectional view illustrating the manner of attaching a pipe coil to the central shaft. Figs. 8 and 9 a are fragmental sectional views illustrating the connections between the central shaft and the feeder tubes.

The embodiment herein shown of my invention comprises a vat 1 which may be of any suitable construction. To the end 1 of the vat is secured a support 2 having a wall 3 that lies against the end wall 1. Upon the wall 3 is a sleeve4 extending through an opening in the end wall 1. The inner end of said sleeve is internally screwthreaded to receive an externally screwthreaded flange 5. To the wall 3 of the support 2 is fixed a gland 6 (Figs. 1 and 5) which projects within the sleeve 4 and serves to retain the packing material 7. The flange 5 and the gland 6 constitute a bearing for a tubular shaft or bearing nipple 8. The other end of saidshaft is rotatably supported in a bearing member 9 which is secured to a bracket 10 upon the support 2. Fixed upon the shaft 8 is a thrust collar 11 which bears against the portion 12 of the support 2.

At the oppositeend of the vat 1' is. a cirulation tank or ice box 13. In the end Wall 1 of the vat and the opposite wall of the ice box are bearings 14 and 15 to support a tubular shaft or bearing nipple 16.

The

shafts

8 and 16 provide means for supporting and rotating a tempering element. Herein the tempering element is shown as comprising a central tube 17 and a spiral pipe coil 18. The central tube and the end of the central tube 17 is secured. Be

tween the sleeves 20 and 21 is a spiral tube 22 which communicates with said sleeves. To the end of said spiral tube is secured the adjacent end of the pipe coil 18. It will be seen that the central tube 17 and the mem bers l9 constitute a shaft having hollow ends which are connected to the bearing nipples or

tubular shafts

8 and 16 and to the coil 18.

At suitable intervals the pipe coil 18 is connected to the central tube 17 by means of feeder tubes 23. At their outer ends the tubes 23 are connected to and communicate with the interior of the pipe coil; and at their inner ends the tubes 23 are screwed with the interior of the tube 17 through holes 26. It will be seen that the tubes 23 serve to convey liquid from the central tube 17 to the pipe coil at various points in the length of the coil, and also serve! to support the coil.

The ring 25 (Fig. 8) which is nearest the outlet end of the coilhas a web 25 and constitutes a plug to prevent the tempering fluid from flowing any farther through the tube 17. An opening 26 establishes communication between the central tube 17 and the feeder tube 23.

The means for rotating the

shafts

8 and 16, the central tube 17 and the pipe coil 18 comprises a shaft 27 supported in two bearings 28 which are carried by the wall 3 of the support 2. The shaft 27 is supported at one end by a bearing 29 which is mounted upon the end wall 1 of the vat. The shaft 27 carries a tight pulley 30 and a loose pulley 31. A spiral pinion 32 on the shaft 27' meshes with a spiral gear wheel 33 on the shaft 8. 7

Means is provided to permit a circulation of hot or cold water through the rotary tempering element. Said means comprises an outlettitting which communicates with the tubular shaft 16. To said fitting is se- I cured a pipe 35 which communicates with a spray pipe 36 located within the upper portion of the ice-box 37 is a drain cock connected to the fitting 38 is an; overflow tube located within the ice-box, the lower end of said tube communicating with any suitable receptacle (not shown). The height of said tube determines the max mum level of the liquid in the ice-box. 39 is a strainer located within the ice-box and connected by means of a pipe nipple 410.- and a T 11 to. one end of a pipe d2 which extends longitudinally of the vat. The other end of the pipe 42 is connected by means of a pipe 13,. to the. interior of the bearing member 9. 14: is a water inlet. pipe. alsocommunicating with the interior of the memher 9. A steam supply pipe 45 having a shut-off valve 46 therein communicates with a nozzle 17. formed integral with the memher 9, said nozzle being axially alined with the, tubular shaft Ilhe rotation of the pipe coil causes a circulation of water through the shaft 8, the central tube 11,. thepipe coil 18-, the shaft 16, the spray pipe. 3.6- and the pipes a0, 42 and 43, back to the member 9.. The heat of the water is imparted to. the pipe coil 18 and thence tothe milk or cream to be tempered- Then the contents. of the vat are to be cooled, the hot water is drained off, and coldv water admitted to. the circulating system through the pipe 14:. When the milk or cream has. been cooled in this way as; much as possible, ice may, if desired, be placed in the box- 13,,the water supply piperl l shut off, and the water caused. to circulate by the rotation of the coil- 18.

i8 (Figs. 1 and 2), is an air-intake. valve communicating; with theinterior-of thesmemher 9-,, for admitting; air to. prevent the formation of a. vacuum. Said valve comprises a body 49 having a plurality of interior guide ribs 50. These, ribs serve to guide. a' vaLve member 51 which is in; theform of an inverted cup.. The member 521' normally rests upon shoulders 52.. The upper end. of the body- 4:9 is closed by a head 53, the lower face of which constitutes a seat for the valve member 51. 5a isa central port in the head- 53-, said port communicating. with. the atmosphere through ports55; Air flows through the ports 5 1 and 55- and around the valvemember 51- 2111(11 thencethrough the tube 56 to the. member'9i. Any

steam or liquid rising in the tube 56 and the body 49 will lift the valve member into contact with the seat 53.

In place of the pipe coil 18, a sheet-metal spiral disk coil similar to the one disclosed in Patent No. 790366 may be used. The opposite ends of such a spiral disk coil are connected to the

tubular shafts

8 and 16 by means of' members 57 and 5% (Figs. 3 and 3 Each of said members comprises an i1";ternally-screW-threaded portion 58 to receive the end of the tubular shaft the coil with its central tube is v supportedupon and attached to the opposite ends of said members. Tempering; fluid is admitted to the coil through openings. 59- and tothe central tube through the opening 60. The fluid lcavesthe coil; through the openings 61. The closed end of the member 5.7 a corresponds in funrrtion to.- the web 25.
