To n/ZZ whom. it muy concern/:

Be it known that LWILLIAM J. RUEF, a citi- Zen of the United States, residing in Quincy,

in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Pasteurizers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My present invention relates to a machine for pasteurizing beer, &c., and belongs to the same class of machines as those shown andone of the bottle-containing baskets and its drain-pipe. Fig.rIV is a sectiontaken on line IV IV, Fig. III. Fig. V is a horizontal` section taken on line V V, Fig. III. Fig.v VI is a detail section showing part of the attemperating and cooling' tank and its supply-pipe. Fig. VII is a detail top view showing a modiiication. on line VIII VIII, Fig.- VII. Fig. IX is a section taken on line IX IX, Fig. VIII. Fig. X is a section showing the regulator; Fig. XI is a section showing one of the diaphragmvalves. Fig. XII'is a view similar to Fig. XI, showinganother of the diaphragm-valves.

Referring to the drawings, 1 represents a tank for holding the attemperating and cooling water, and 2 is a tank for holding water of maximum temperature. A Fitting over these tanks and extending into the latter is a housing or hood 3, thereby forming a leg or space 4in which the beer is attemperated, a leg or space 5, in which the beer is heated to and for a suiiicient length of time retained at a maximum temperature, and a leg or space 6, in which the beer is cooled. The bottles of beer are conducted through these legs by means of a carrier composed of endless chains Fig.`VIII is avertical section taken .driven by any suitable form of motor (not shown) connected up to the shaft of one of the sprocket-wheels 8. Communicating with Vthe tank 1 is a rotary pump 10, from which.

extends a pipe 11, having a branch 12 for discharging attemperating-water into the baskets 9 in advance of the introduction of the water of maximum temperature and a branch 13 for discharging cooling-water into the baskets after the bottles have been submitted to the actionof the water of maximum temperature. In the pipe 12 is a diaphragm-valve 14, (see Fig. XL) such as is shown in my Patent No. 701, 622, dated June 3', 1902. The air-supply pipe 15 of the diaphragm-valve communicates with a regulator 16, located in the tank 1. The regulator is shown in Fig. X and consists of a cylinder 17, secured to one wall of the tank 1 and having a tube- 18, that extends into the tank. Within the tube 18 is a thermostatic bar or rod 19, the inner end of which is made fast to the end of the tube 18. In the outer end of the cylinder, 17 is fitted a plug 20, into which is tapped a stem 21, having a port 22, that communicates with the pipe 15. The inner end of the stem 21 forms the seat for a valve 23 on the outerend of the thermostatic rod 19.

24 is a compressed-air pipe tapped into the plug 20 and which communicates with the interior of the cylinder 17.

When the temperature in the tank 1 falls below a given point-say 90o Fahrenheit-.- the bar 19 will contract and open the valve 23. Compressed air will then pass through the pipe 24, which is connected to a suitable compressed-air tank, (not shown,) through the stem 21, and through the pipe 15 to the diaphragm-valve 14, thus causing the valve to be closed and shutting ofi the 110W of' water from4 the pump 10through a pipe 12 into the baskets 9. When the temperature of the water in the tank 1 rises above the desired temperature, the valve 23 closes again, thus permitting the How or' water through the valve 14 and pipe 12 into'the baskets 9. As the baskets become nearly filled with water they overiiow back into the tank 1-that is, so long as they are passing through the leg 4. This overow is from basket to basket and is permitted by means of a double-legged pipe, (shown in Figs. III and IV,) and which consists of a leg 33, communicating at bottom with the basket with which it is pivotally connectedy and at top with a leg 33, having a discharge-opening 37, that terminates beneath the basket, so as to direct the water into the basket beneath.

28 represents a rotary pump communicating with the tank 2 and from which a pipe 29 extends to the top ot' the machine, where it is provided with branches 30, having nozzles 31 for discharging hot water into the baskets. The left-hand nozzle 31 is located in the upper part of the leg 4, and this nozzle is provided with adiaphragm-valve 32, corresponding to the valve 14, except that it is held open by the compressedair pressure instead of being closed by the compressed-air pressure, so that when the valve-14 is closed the valve ,32 is open, and vice versa, the result being that when Athe water in the tank 1 falls below the desired temperature the valve 32 will be opened and hot water will pass through the baskets in the leg 4 into the tank 1, and thus restore the temperature in the tank. As soon as the water rises above the desired temperature again the valve 32 will be closed and the valve 14 opened, and thus the cooling of the water caused by attemperating the cold beer is constantly counteracted by hot water passing from the tank 2 through the diaphragm-valve 32, the result being that the water in the tank l is maintained at approximately a uniform temperature at all times.

As the carrier is passing through the leg 5 the beer is submitted to the action oi' the water of maximum temperature which overiiows from the baskets through the conduits 33 33a back into the tank 2, where it is maintained at the maximum temperature in any suitable way-as, Jfor instance, by means or' a steam-jet 60, (see Fig. II,) located in a pipe 61, that connects the two ends of the tank together. In the pipe 62 ot' the jet-pump is a diaphragm-valve 63, corresponding to the valve 14, and connecting with the diaphragmvalve is a regulator 54, corresponding to the regulator 16. When the water falls beneath the point desired-say 148C Fahrenheit-the regulator 64 will open the valve 63, admitting steam to the tank through the pipe 61. As the carrier is passing up through the leg 6 the beer is submitted to the action of coolingwater deposited in the baskets through the pipe 13, which, as stated, communicates with the pump 10, that is located in the tank l,

and the bottles are thus gradually cooled down before being exposed to the atmosphere. As the baskets leave the top ol the leg 6 the water commences draining therefrom into the baskets beneath, this being ell'ected through means of the swiveled double-legged pipes 33. (See Figs. III and IV.) These pipes are connected to the lower portions ol the baskets, as shown in Figs. III and V, and they are slowly turned into a horizontal position by coming against a pin 36. (See Fig. I.) As they are turned the water flows from their lower extended ends 37 and is discharged into the baskets beneath and iinally back into the tank 2. rl`he bottles are thus gradually cooled down as they move upwardly through the leg 6. Then the carrier is moving downwardly from the sprocket-wheel that is located over the leg 6, the baskets are empty ol water, so that the beer can be removed about the poin t B. Beneath this point there is located another stationary pin 38, against which the pipes 33 impinge and are turned back to their upwardly-inclined positions, so that the baskets are ready to take and hold water again when they reach the point A.

Any loss of water in the tanks is restored through pipes 40, provided with valves 4l, to which are connected lioats 42, located within the tanks. (See Figs. I 'and Vl.) \\"hen the water falls beneath the desired level, the floats will by descending open the valves 41, thus permitting a flow ol water into the tanks from the pipes 40, which are connected with any suitable source ot' water-supply.

54 represents stationary rails tor guiding the endless chains of the carrier where they are deiiected in the course oil their travel.

In Figs. VII, VIII, and IX, l have shown a niodiiication of the double-legged pipe 33 33, which consists in locating a iixcd waterconduit at one end of the baskets, which conduit consists ot a leg' 25, communicating with the lower part of the basket and at top with a leg 26, having a lower extension 27, that terminates beneath the basket. 'lliis conduit permits the overiiow ot' the water from the basket, and to discharge the water from the baskets (which in the other form is eilected by the turning of the pipe 33 33, as described) I employ a valve 27, which is normally held to its seat by a spring 27"'. The stem ot the valve projects some distance beyond the basket and is adapted to come against a suitable stationary pin to etliect the opening ol the Valve when the baskets reach the top ol the leg 6. I/Vith a machine thus constructed a very small tank may be utilized, inasmuch as the attemperating and the cooling et the beer is eifected without the use oi. a l'ank to hold the water through which the carrier is passing at the time that the atten'iperating and cooling processes are being carried on.
