, To all whom, t may concern.-

Beit known that I, AAGE J ENsEN,a citizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented a new and useful Improvement in Liquid-Ripeners, of which thefollowing is a specification.V

My invention is in the nature of a device for cooling or heating and simultaneously agitating liquids-as, for instance, in ripening cream preparatory to churning it; and it consists in the novel construction and arrangement of receptacle with means for cooling or heating the cream, as may be desired, and at the same time agitating it, as will `be hereinafter more fully described with reference to the drawings, in which- Figure 1 is a vertical central section. Fig. 2 is a plan view. Fig. 3 is an enlarged vertical section through the breast of the tank;

Figs. 4 and 5, enlarged detail sectional views v showing the step-bearing and cream-outlet.

Fig. 6 is a bottom plan View of the cream-receptacle. Fig. 7 is a vertical section, and Fig. 8 an enlarged horizontal section, of one of the gangs of pipes or tubes, and Fig. 9 is an enlarged cross-section of one of the tubes of the same.

In the drawings (see Figs. 1 and') the tank or outer casing is constructed as a vertical cylinder having its outer wall composed of wood staves S, with a lining of galvanized sheet-steel Q, and a layer of corrugated sheetasbestos R between the said lining and the staves. This corrugated sheet forms air-cells and has a layer of paper on each side of it, as

seen in Fig. 3. The inner wall A of the receptacle is made of tinned copper of cylindrical shape and with a conical bottom, thelowest point of the bottom being offset laterally from the center and communicating at E2 with a discharge pipe E', having a cutoif gate E3.

Around the receptacle A is arrangeda number of steel wire hoops U to reinforce orbracel the said'receptacle. At the top of the receptacle A is a circular angle-iron `B, riveted and soldered to A.

C is an annular inclined breast fastened per'- manently to ring B at the top and fastened at y the bottom edge to the upper edge of the outer casing by screws M, which (see Fig. 3) are threaded into an angle-iron rim O, with a rubber gasket N between.

T is a steel hoop arranged outside the upper ends of the wooden stavesto hold them in place, and Fis a wooden hoop arranged inside the staves and above the air-cells to prevent crushing the same. The horizontal flange of the angle-iron O covers the tops of the staves and the hoops T and P, and between the vertical fiange of the angle-iron and the wooden hoop P is clamped the steel lining Q. On top of the fianged ring B rests a cork packing-ring J, held in the groove of a channeled ring I, securedto the lower side of the hinged lid K.

The cover of the inner receptacle Ais lined with tinned copper and is made in three sections K K' K2,of which the middle section, K', is stationary and K and K2 are lids or doors, connected by hinges m m to the stationary portion. The sections m of the hinges are extended to the circular edge of the'hinged lids and are formed with curved seats m", that receive the cam-heads of short levers m2. These levers are connected by links m3 with the annular breast C, as follows, (see Fig. 3:)

D is a brass casting fastened by screws F to thel annular breast and having a loop d, in which issecured the pivot-pin of the links m3. When the levers m2 are thrown out of the seats W, the hinged side may be opened; but when the levers are in the position shown in Fig. 3 the cam-heads draw the lids tightly down, so that the cork packingJ makes an airtight joint. Y

The bottom of the receptacle A (see Fig. 1) is made of double thickness, theinner layer Al being tinned copper and the outer layer A2 of galvanized iron fastened together throughout'the entire surface lby numerous closelyplaced rivets a, (see Fig. 6,) and the outer layer of galvanized iron is4 formed into vertical flanges a2, radiating as shown. These ribs or flanges a2 impart stiffness to the bottom, so as to enable it to properly sustain the central shaft and rotating gangs of tubes without vibration.

X represents the gang of tubes which are connected to acentral hollow shaft X,which shaft is provided with a special step-bearing at its lower end and at its upper end extends through a stuffing-box 14 in the middle stationary part K of the cover. The step-bearing (see Figs. l and 4) consists of a circular plate 1, having an inclined bottom surface and a screwthreaded central hole. Theinclined bottom surface is to lit the incline of the conical bottom of the cream-receptacle, since the lowest point of the conical bottom is eccentric to the shaft. l'nto the screw-threaded hole in the plate 1 is turned the lower screw-threaded end of a step-bearing 2. This step-bearing is made conical on its exterior surface and has a central hole through it to form a passage-way for liquids. Surrounding the exterior conical surface of bearing 2 is a swiveling sleeve 3, connected by a screw-thread' with a sleeve 4, screwed onto the lower end of the hollow shaft X/, so that this hollow shaft and its gang of tubes X and the sleeves 3 and 4 rotate together. The conical inner surface of sleeve 3 fits with a water-tight ground joint onto the conical exterior of step 2 and always wears to a'water-tight fit. Into the upper end of the step-bearing 2 is screwed a stationary stand-pipe 5, which extends up to nearly the top of therotary gang of tubes X. The gangs of tubes communicate with the top of the hollow shaft at 14 and communicate also at the bottom with the hollow shaft; but there is no passage-way through the hollow shaft from its upper end to its lower end; but fluids passing through have to pass through the gangs of tubes on each side of the hollow shaft.

The rotating gangs of tubes 6 are arranged vertically and parallel to each other and communicate at top and bottom with the horizontal pipes 7 7, which connect them with the hollow central shaft. The vertical tubes 6 are in cross-section of a sharpened elliptical shape, as seen in Fig. 9, with the major axis of the ellipse set tangential to the circle of rotation, as in Fig. 8, so that these thin tubes cut edgevvise through the cream with the least resistance and also afford the largest superiicial area for a given cross-section. These tubes also get continually larger from the center outward, as seen in Fig. 8. This is to give a larger volume of cooling or heating medium within in proportion to the larger quantity of cream which these outer tubes pass through in revolving through larger circles of cream. In this wayl get a better distribution of heating or cooling effect from the gang of tubes throughout the body of cream in receptacle A( The circulation of the heating orcooling medium through the gang of tubes X is directed through them in various ways. To cause the circulation to take place first through the outer tubes and then successively through the inner tubes, l construct the tubes as shown on the left-hand side ol Fig. 1 Wthat is to say, l. locate in the upper horizontal pipe 7 a longitudinal partition 8 with short transverse partitions 9 9 in the lower half of this pipe, while in the bottom pipe 7 on the left-hand side the transverse partitions 1() extend all the way across the pipes. l In this case the liquid passes from the space 14 in the hollow shaft horizontally over the top of longitudinal partition 8 to the outer tube, then descending itis turned up bythe lirst partition 1 0 of thelower pipe and rises through the second tube from the outer one and after passing therethrough is turned down by the transverse partition 9 into the next inner parallel tube, and so on it continues to the bottom part of the central hollow shaft. On the right-hand side a longitudinal partition 11 arranged in the lower pipe 7 with short transverse partitions 12 above it, while the top pipe 7 onl this side is provided with transverse partitions 13,like the partitions 1() on the left-hand side. ln this case the cooling or heating liquid passes down first through the inner tube and then up through the next outer tube until it reaches the outermost one, and then it returns beneath the longitudinal partition 11 to the bottom part of the hollow shaft X. lf desired, both sides of the gang of pipes may be made like the right-hand side of Fig. 1, as shown in Fig. 7, o1' both sides may be made like the lefthand side of Fig. 1. As the heating or cooling liquid passes into the lower end of hollow shaft Xl it rises therein outside of stand-pipe 5 and overflowing into the upper end passes down through stand-pipe 5 and hollow stepbearing 2 and through the bottoni A A of the cream-receptacle to the space outside the creani-receptaclc and between it and the outer casing. The object of this stand-pipe 5 is to prevent the cream from passing out ol the receptacle Ain ease the bottoni bearings should become leaky, as the stand-pipe 5 rises to a point above the level of the cream in the rcceptacle A.

The cream-outlet Efroln receptacle A, Fig. l, is provided with a special connection (shown in detail in Fig. 5) in which a ilaliged plate (l is secured to the conical bottom A A2 and is clamped to the sheet-metal lining of the bottom of the casing by a nut cf and rubber gasket e. The socket of the plate c is drilled out and screw-threaded interiorly to receive a screw-nipple c, which has a screw connection with the plate c, the nut c2, and also an elbow 2*, connecting with the discharge-pim, E'. The inner wall of the nipple is llush with the opening in plate a, which makes a smooth passage-way for the discharge of cream with no angles or crevices for the collection and retention of sour cream, thereby making a sanitary constructior. This creamoutlet forms the only support for the bottom of the cream-receptacle, as seen 1n Fig. l, and as the hollow conical step-bearing has no IOO IOS

IIO

support beneath it the. value of the special vconstruction of the bottom of thel cream-receptacle will now be understood,the double.-

bottom with stifening-ribs preventing the vibration of the bottom from the action of the moving parts'.

Where the hollow shaftXpasses through"V the middle section of the cover, said shaft is provided above the stuliing-box 14 with a bevel-wheel 22, which is engaged by a bevelpinion-23 on a short horizontal shaft, bearing at its outer end a driving-pulley 24. .By this means the hollow shaftand gang of tubes are rotated. Above the bevel-gear the hollow rotary shaft X is connected to a stationary pipe 15 by means of a stuiiing-box 25.- `This pipe is open at its upper endl for the recepa T-coupling 16.

The hinged sections K Kzof the cover when raised allow the cream to be' introduced.

In the side of the outerzwall of the casing* near the top there is an overflow-pipe L2 for water.

Rzis an air-inlet, through which compressed air may be introduced ontop ofthe cream to force the same ythrough the outlet-pipe .E

and up through aconnecting-pipe to any vessel located higher than the ripener.

The operation of my ripener is as follows: The cream-gate E3 beingclosed, the cream is introduced into lthe space within the receptacle H through the covers KV K2 until the receptacle is filled and the cream surrounds `perature.

eXteriorly and completely immerses the gang of tubes X. Gold brine or ice water isnow introduced through the top of pipe 15 and passes down the hollow shaft X to the point 14and then traverses the interior of the gang of tubes-X and passing out at the bottom rises to the top of.stand-pipe 5 and descending through the same and through the hollow bearing 2 gains the space below the bottom of the receptacle A .and rises between the same and the outer casing, escapes at the overflow L2, carrying away the absorbed heat of the cream.` As the water passes through the gang of tubes X the latter is slowly revolved, which causes every portion ofv the cream to be reached by the cooling stream of water in the tubes, and which tubes also vact as an agitator to thoroughly stir the creamand render it 0f uniform yconsistency and tem- When the cream has been sufficiently treated itis drawn off through the gates E3. 1f instead `of cooling the cream itis pipe 20, and this draws the water from around the receptacle A through pipe 19 and after heating it sends it through pipe 21 into the hollow shaft and the rotating gang 0f tubes,

Ywhere it raises the temperature of the cream.

This closed circulation vof" warm water from` the annular space between the walls of the the hollow shaft and tubes to the annular space again may be continued until the proper `temperature and ripening effect is secured.
