Application filed March 16, 1910. Serial No. 549,789. v I I H To allwhom it inay concern:

Be itknown that I, AUGUST Tmssn, a citizen of the United States, residing at Chi cago. in the county of Cook and State of Illinois. have invented a new and useful Improvement in Pasteuriz ng Apparatus, of which the following is ti-specification.

My object is to rovide is construction of pasteurizer by which the pasteurizing op-. eration may be carried on-continuously, and under pressure when'desired, whether the pasteurizing agent bestea'm or water, and

by which pasteurization of the material to uniformly.

Referring to the accoinpanymgflfawmge- F gure 1 shows by a view IIIQIGVat-IOR a be treated may efi'ected expeditiously and past'euriziug"apparatus constructed in ac-,

cordance with my inventiom'thc apparatus illustrated in this figure being designed for use with-water as the paste izing agent. Fig. 2 is a view in elevation o {the pasteurizing up aratus showing portions thereof in section, t is view being taken the right hand side of Fig. 1' and. at, right angles thereto and the section bein taken at line 2 on Fig. 1 and viewed in t e direction of the arrow.

Extending through the center-of the rings 25 and journaled 1n bearings- 29, is n shaft 30 which carries two spa'ced' V .g gde 31 and. 2, respective of--f t conical form tap g W y as mpre sented at 33 in Fig.2, and journaled on. these heads are internally tapered sleevesjfifi and 35, respectively, which are provided in with radially exten g arms 3.6-:ind 37,-respectively, connecting with. the opposite-1 ends of the receptacles 16 -to 24 inclusive as loo illustrated of those-shown in Fig. 2.- sleeve 34.. and arms 36 contain conduits=38 to 46 inclusive, which are spaced equidjs'-; a f taut from each other and'con municate re spectively, with the interior of the. reoep;

tacles 16 to 24, inclusiveot their -'left-hand ,l ,i'

sleeve 35 and arms 37 contain conduits 4.7

to 55 inclusive which are likewise spaced equidistant'fromeach other and communicate, respectively, with the interior. of the receptacles 16 to 24 inclusive at their righthand endsin F g. 2, when the receptacles are inthepositions illustrated in Fig. 1;

In the particular construction illustrated,

the head 31 contains seven angle-shaped conduits 56 to 62 inclusive which open through its periphery and its outer face as repre sented of those conduits illustrated in Fig. 2, the conduits 56 to 62 inclusive being so arranged that when the receptacles occupy the positions represented in Fig. 2 they will communicate with the conduits 10 to 16 inclusive, respectively. The conduits 56 to 62 inclusive communicate with pipes 63 to 68 inclusive and an exhaust-pipe 69, respectively, the pipes 63, 64 and 65 leading into the lower ends of tanks 72, 71 and 70, re-' spectively, and the pipes 66, 67 and 68 containing pumps 73 are adapted to discharge into the tanks 70,, 71 and 72 respectively,

- these tanks being designed. to receive water for circulation through the receptacles 16 to 24. inclusive as hereinafter described, and maintain it at different degrees of temperature for producing gradual heating of the material to be pasteurized, pasteurization of the same and subsequent cooling thereof, as for-instance the water in tank 72 may be maintained at 18 R, that in tank 71\at 35 R. and that in tank 70 at 48 1%., though it will be understood from the following description ofthe operation of the apparatus that the temperature of the water in the different tanks may be varied as conditions require The head 32 contains four passages 74, 75, 76 and 77, which are 'sodisbottles,'- cans orthe like,' 'c'ontaining the mar. terialto be pasteurized are represented at.

'7 9,-these supports preferably being m'ade'of-v posed as to cause the conduits.-18, 49, 50 and 51 to communicate with the conduits 5 5, 5 1, 53 and 52, respectively, when the receptacles occupy the positions illustrated-1 in Fig; 2 for effecting circulation therethrough of the pasteurizing water as hereinafter described.

It will be notedfrom the foregoing that thestationary heads 31 and 32 form with their cooperating sleeves 34; and 35, respectively, valves for the conduits at the opposite en s of the receptacles for controllin theflow of water from the several tanks into. and out of the latter when-the rings 25 are intermittently rotated andthe, receptacles carried thereby niove. in a circular path.

Each receptacle l6to 24 inclusive is provided-at its opposite end with a swinging door 78,1.which, when closed, renders the rcceptacle fluid-tight. The supports forthe wire fabric in the form-.ofibaskets provided on "their under sides with rollers ,dQ- which rest onythe inner "surfaces oftlie receptacles-1- and b .taine which the supports are always main less of the positions occupied by the receptacles during the operation of the apparatus as hereinafter described.

rings 25 are caused to be intermittently romoved in'a circular path to advance the redrawal of the pasteurized material, their-re charging with-new material and subjecting the material charged into the receptacles to the pasteurizing agent circulated tl..ough

termittent movement may be effected in any desired manner, convenient means for accomplishing this purpose being those repre sented, a description of which is' as follows: The gears 28 mesh with pinions 81 rigid on adapted to meshwitha mutilated gear 84 carried on a shaft 85 driven-in any suitable manner. The effect of driving the gear 83 "from the mut-ilated 'gear 84 is that of cansingthe rings 25 and-receptacles 16 to inclusive to be rotated-throughout a portion only of the rotation 'i' the shaft 85, the gears being so proportioned that the receptacles are moved a predetermined distance with each engagement of the gear 84 with the gear 83 and are causetiltofremain at rest instance in the construction illustrated the recepta'cleswould be: atrest foij'aeriod five times ,as long as the period uring which they move, and each time the gear 84 engages with thegear '83 .the rings and rcceptac es'would travel'one ninth of a coin- 'is in communication-with the-co m:li 1 il% 55- of casing 24 throu 'h the medium oftherpas- :1 3,?4 and 6; the conduit 40-of casing 18is "open: to. the pipe 63 leading from tank 72 through-the medium of the conduit {56 in zt'he:headi31, and the othen-lcgnduit 4910f re-' ceptacle l8.-communi'cates with the conduit n condition therein, regard-5 54 of receptacle 23' through the medium of In the. operation of the apparatus, the 70. tated and the receptacles 16 to 24, inclusive,.

W hen the gear 84 in its' rotation meshes with the gear 83 the receptacles are' caused to travel in a circular path to the left in F1 1 a (118 'tance equal to one-ninth of the clrcumfera once of the circle n whiclrthey l'1e,'t o cause all of the receptacles to be moved one-mnth of a revolution in the direction indicated by the arrow in'Fig. 1. 'lhe 'e fi'iect of thus operating the apparatus is to ci'iuse' receptacle l7'to be moved into-the position occupied by receptacle 16 in' Fig. 1 and advanrre each of the other receptacles to the positions" formerly occupied bythe next receptacle in As the heads 31 and 32 are stationaryand the sleeves 34 and 35 rotate with the rcceptacles,tthe operation of the latteras described destroys ,the. couunuuicatrons bctween'the receptacles descrihei'l when lIl'tl'lG posit-ions illustrated ll] Fig. l and' 'establish -s new comuuiuicatimis between the several receptacles asis manifest from the drawii'igs. The receptacle 17 having been emptied-ofthe water contained therein by drainingit-into thereccptacle 16, it is now in a position-t0 permit of the removal of the pasteurizin'g material and the introduc-v tion therein of raw material to be. asteur-' ized zt-he-water'iu receptacle 18 (raining sis.'during-this.operation into receptacle/16. It.

will be noted that by the time the receptacles have made a complete rotationby theinter- -1nittent action referred to, the material stituting for it raw material, is being performed in the receptacles as they successively occupy the position representcdof casing 16 in Fig. 1, the material in the other receptacles is being subjected to the water from'the tanks 70, 71 and 72, and thus the operation of the pasteurizer is rendered continuous. The parts of the drive mechanisms -for the receptacles may be so proportioned as to provide as long periods of rest, during drawing the pasteurized material, and su'bwhich the 'pasteurizing fluid is'actingupou.

the material, as desired.-

To insure the discharge of thewater from the several receptacles they successlvely occupy the position represented of recepta ole 17 in Fig. 1, 1 provide on each receptiv cle a vacuum .valve 200 which operates in a. well known manner to permit air to enter the receptacles when the internal pressure is less than that of the atmosphere. 7

While I prefer toemploy a plurality of. tanks for furnishing water to the receptacles .at different temperatures and to -provide nine of the receptacles for the material to be pasteurized, I do notwishto be understood v as intending to limit my invention'toil is feature of the construction, as the number of receptacles may be increased or diminished as desired, and likewisc'the number-of tanks, in some cases the use of water at pasteurizing temperature only being desirable.

In 'Figs. 10 to.13 inclusive, I have illustrated my invention as applicable to the use i of steam as the pasteurizing fluid.- In this construction, in which the parts corresponding to those shown in the preceding figures are designated by the same numerals, the

head 86, which corresponds to the head 31 of the preceding figures, dili'ers therefrom 1n the particular of having nine right-angled conduits 87 to 96 inclusive instead of.

the seven provided in the head 31', the sleeve 97 cooperating therewith and corresponding to the sleeve 34,- and the head 98 and sleeve 99 corresponding to thehead 32 and sleeve 35, respectively, being of the same jconstrucion and provided with the same conduits and passages as illustrated and described of thesimilar parts 34', 32 and 35, respectively,

of the-preceding figures, excepting that the head 98 contains a port 201 which registers with the passage 47 when the receptacles occupy the positions represented in' Fig. 10

and is adapted to register successively with the passages 48 to 55 inclusive as the receptacles are advanced in their circular path of movement, as hereinafter described. In this construction, the conduits 87 to 96 inclusive communicate with ipe's 100 to.108 inclusive, respectively, the ipes 101 to,104 inclusive communicating with" a steam-supply pipe 109; the pipes 105 to 108 inclusive'communicatin with areturn steam-pipe 110, and

the pipe 100 serving asan exhaust, the pipes 109 and 110 being connected with any suitable source of steam-supply for introducing steam into the pipes 101 to 101 inclusive,

. thence through the conduits 88 to 91 inclusive and through the conduits 39 to 12 inclu sive, thence through the receptacles 17 to 20 inclusive, and from these receptacles through the receptacles-21 to 24c-inclusive communi eating therewith through the medium of the 20 valve formed of the parts 98 and 99 as described of the construction illustrated in the preceding figures. Steam courses through the various receptacles containing the mate rial to bepasteurized at alltimes, excepting when such receptacles successively occupy the positionpccupied by receptacle 16 in Fig. 10, in which position its steam conduits are closed to the steamsupply and communication is made between it and the exhaust-pipe .100 which enables the steam to escape from the receptacle to place it n a condition in 'which its pasteurized contents may-be removed and raw material for pasteurization may be substituted. It is referred that the conduits for each receptac e leading into the valve formed oi the parts 96 and 87 open into a pipe terminating in a ,hollow ringshaped' pipe 111, having a section thereof broken away to afford oppositely directed openings 112 which, when the receptacles area at the lowermost point reached bythem in their movement in a circular path, extend :close tojthe bottom of the receptacles and serve {to permit of the withdrawahunder thepressure of the outgoing steam of the waterof condensation collected therein.

The receptacles of this construction may bedriven as described of the receptacles in the preceding figures, to cause them to successively-assume the position represented of receptacle 16 in Fig. 10 to permit-of the removal therefrom of the pasteurized material and the substitution therefor of material to be pasteurized. The 'port 201 communicates with a pipe 202 whichleads to any suitable source of compressed air supply whereby when the receptacles successively assume the position represented of receptacle 16 in Fig. 10, the steam will be forced there-- from through the exhaust-pipe 100.

A modification of the receptacles of the construction shown in Figs.'l to 11 inclusive is. represented in Figs; 14 and 15. .In this case, the receptacles instead of remaining in fixed, position and inverting as they move through a circular path, arepivotaii y sup ported to cause them to remain upright at all times, a description of the particular construction illustrated being as follows: The arms 36 and 37 are provided toward their outer ends with transversely-extending bearings 113 in which tubular extensions 11a carried by receptacles 115to123 inclusive are journaled, these tubular extensions comniunicating with downwardly-extending conduits 124: in the receptacles, and these conduits opening into the interior of the latter. The receptacles 115 to 123 inclusive are door-controlled at" their ends -as described that uniform pasteurization may be effected.

It will furthermore be noted that by pro:.

viding a plurality of receptacles adapted to be maintained, =during the pasteurizing operation inair-tight condition,- the pasteurizing medium may be circulated or passed therethrough under any pressure desired, which is of especial advantage in the case of pasteurization of beer in bottles, in which case theincreased pressure exerted by the gases formed in the bottles may be compensated for to equalize the strain on the latter and thus prevent breakage from this cause.
