when the lid is sealed on the can, a vacuum will be created inthe can. This is ofv great advantagefrom many points of view.

In a canning plant, which is arranged for y canning various kinds ofl food as well as canning dilferent sizes of cans of the same food, it is of considerable advantage, as the equipment for doing this work is already arranged, `to subject the cans to various heating or cook- I ing periods.

It is one of the objects of the present invention -to provide an exhaust box or cooker which will accomplish the before mentioned f cooker from the inlet opening to the outlet features of advantage in a very 4simplemanner. f 'Y `vide an exhaust box or cooker having a plurality of disks connected together in a manner-to permit cooking food in open cans and variable as to time of cook.

"A further obj ect of the invention is to provide van exhaust box or cooker having disk means for giving the open cans of food a pref determined movement through the box or opening or any portion of said movement.V

` A further object of theinvention is to provideran exhaust box or cooker having disk means arranged to move open cans of food' along one side portion ofthe box from one end to the other and lthenacross said end to and returning along the other side portion of the box, and also having means for shunting the cans at intermediate points from one side of the box to the other. i

A further object of the invention is to proofthe devices for shunting the cans from one side of the box tothe other.

A further object of the invention is to provide an exhaust box or cooker which is of simple construction, is strongand durable and Ais well adapted for the purpose desired. 3

With the above and other objects in view,

lthe invention `consistsof the improvedV exhaust box and cooker and its parts and comwbinations as setforth in the claims, `and all equivalents thereof.

In the accompanying `vdrawings `in which `the same `reference characters indicate the same partsin all of the views: f

Fig.` 1 is a top view of the improved exhaust box or cooker, the cover being removed 'to show the parts therebeneath;

Fig.2 is a'longitudinal sectlonal view thereof, taken on line 2--2'of Fig.,1;;

Fig. 3 is a vertical sectional view of one of the disk members and its bearing and aportion of the frame;` j

. Fig. 4 is a side view on a larger scale, parts being in section, of one ofthe disk members and `one ofthe `shunting ldevices and Fig. 5 is a top fragmentary view o'one-of the-shunting devices. n. v l 1. f f

- Referring to the drawings,`- the reference numeral 8 indicates an exhaust box ortank of rectangularform, which vis supported by angled legs 9 connected tothe cornersand cover 10 closes the upper open portion of the tank. yA rectangularvframe 1 1 within the box or tank is provided .with transverse frameA members 12 having depending bearin s 13 vconnected thereto. Vertical shafts 14 a justably journaled in said bearings 13 have geared idisks `15 mounted on their upper ends. Said gears extend in two parallel 'lines adj acentop- `posite sides of the tank, the disks onthe inner sides of `the parallel lines being staggered with relation to theouter lines of dis s and in mesh therewith, as ycleanly shown in Fig.'y 1.

At one end of the box.` a `disk gear 15 is journaled which is in mesh with the two inner c disk gears lofthe opposite sides of the box,

A further object of the invention 1s to pro. vide an exhaust box or cooker having a very simple means for controlling the zuiljustments'` sorv thatall ofthe disk gears mentioned .Will be in meshV andform acontinuous train of gears kfrom one side of. theboxto the other.

vmedial portions of the tank. lAremovable A shunt disk gear 16 is journaled on one of the medial transverse frame members and is in mesh with the opposite side disk gears adjacent thereto, to provide a shunt can track 5 between the disks of the opposite sides of the box. Similar shunt disk gears indicated by dotted-lines'16 may be Vused if it is desired to rovide other shunt can tracks.

he box 8 adjacent one side end is provided with an inlet opening 17 and on the opposite side end is provided witha discharge open# ing 18, and a feed disk gear 19. inmesli with an adjacent gear is adapted to feed open cans of food through theinletopening and 15 into the boxl8, while a discharge diskgear :20 inmesh with anadjacent gear 15is ada ted to discharge the cans 21 through the ischarge openingf18 for further disposition.

1 Apinion 22,mounted onjashaft 23 ,in one 20' corner ofthe box, is in mesh with the adjacent diskgear 15 and drives the before-men- .'tionedv chain Vof disk gears. The vertical shaft 23 1on'which the pinion 22'is mounted,

` isjournaled in the same manner as the shafts Q5? `14. A bevel gear 24 mounted on `the upper end of the shaft 23 is inmesh with a larger y:bevel gear 25' mounted on ahorizontal-shaft y26 which is provided' on its outer end portion with a tight pulley 27 anda loose pulley 28.

30' Said bevel gears and pulley 27 are the means for-driving the machine, the power for the pulleys being derived by belt means (not shown')from.a'distant source of power.

Guide bars 295 extend above and alon ythe T5351adva-ncingportions'of thedisk gears tol orm *40 accommodate a ysingle line `ofcans when inA 't :upright position, and the rotation of the advancing portions of the disk gears upon which guideway.

1 45" .The shunting. disk gear 16 isalso provided withrshunt guide bars 30 which are connected to and extend from the Gfuidev bars29on one lside of.I the .box to the similar guide bars 29 on f the otherisideof the box.v The guide bars29. W Yadjacentfthe shunt VguidebarsBO are formed l withgates 131 and 32 which may be :swung: 'frtinthe solidline positions to the dotted line 'positions indicated in Fig. 1 lto. shunt the cans from one'v side ofthe box to the other before 'swung to position to close t e'passageways 33 between 'the'guide bars 29. A crank lever lirO'l and links. 34'.V control the adjustment of the gates. j

n It is to be understood that the dotted line shunt diskgearsinay also be: provided with shunt guide bars and gates iff desired. The` '5guide bars areheld in position by angled supclosed Lto retain the water'during thevcooking porting members 35 which are mounted on the transverse frame members and extend upwardly and are connected to the guide bars.

The height of the disk gears with relation to each other is adjusted by means of set screws 36 which are'threaded through caps 37 mounted on the lower ends of-the bearings 13 and'bearv against the lower end ofthe shafts 14. Y. lLock nuts 38 hold the set screws in adjustedposition. Y

'iii-eportions^@faitv4 guide bars 29 which j project from the opposite sides of the box are formed with bottom portions to forni chutes `39 and 40 for feeding cans to the box and dis-` y charging cans therefrom.

The' bottom portion ofthe box is provided with an outlet opening 41 for discharging the water of condensationffroml the box, or in case hot water is'used, the openingmay be operation.

` Perforated steamI `pipes' 424 extending around the inner sidesof thebox andv central portions thereof, are positioned to spray jets of steam into the boxf and around the cans :as the cans are rolled'and advance between the guide in a zig-zag course from the inlet to the outlet opening. As the cans rest upon the advancing portions ofthe disk gears, the cans are moved forwardly in a zig-zag mannerv fromoiie endof the guide to the other. In somekinds of foodwhich does not require as much cooking as other kinds, the cans may be shunted across the medial portion of the box. and Awill be subjected to approximately: one-lialf of the cooking period.- -2Further more, disk gears and guide bars may be mounted inthe manner indicated by dotted I cooking periods.

It is-"to be understood ythat the train of fzfthe cans rest, will advancesaid cans along the geared disks may be arranged invarious ways to provide variable cooking periods without departing invention. l l

.fFroin' the foregoing descriptionit will be seen that an exhaust box or cooker issprofrom the spirit lof the.

.vided which isveryvsiinple .in'constructiom is efficient inv operation and permits variable causare in 'open position. j What I claim as my Ainvention is:v

An exhaust box or cooker,'coin`pris ing a receptacle having an inlet opening and an outlet opening, 'means for lheating the interior thereof, rotary'means and a guide'extending in two spaced linesforn'ioving open cans of foodVV through the receptacle in a cir- Vcuitous path from the inlet Vto the outlet: opening of the receptacle to provide acertain time period for cooking the foodlwithin the openv cans, and other rotary means between the two lines operable when desired `for shunting the open lcans from one portion of cooking periods of cansof y'food lv'vhile `the the line of normal path of travel of the cansk to another portion of the line of normal travel of the cans to shorten the cooking time period of the open cans of food.

2. An exhaust box or cooker, comprising a receptacle having an inlet opening and an outlet opening, means for heating the interior thereof, spaced lines of rotary disks for moving open cans of food through the reeeptacle from the inlet to the outlet opening, means for guiding the cans in a circuitous path from one disk to another in passing through the receptacle to provide a certain time period for cooking the food within the open cans, and other rotary disks and guide means interposed in the space between the lines of disks for shunting the cans from. the line of disks on one side of the space to the line ot' disks on the other side to shorten the cooking time period of the open cans of food.

3. An exhaust box, comprising a closed receptacle having an inlet and an outlet opening, geared disks positioned within the receptacle and extending in two spaced zigzag formation lines from the inlet to the outletopening, curved guide means positioned above the disks and extending from one end to the other of the train of geared disks for guiding cans on said disks, another disk interposed between the two lines of disks and geared thereto, another guide means positioned above the last mentioned disk and connected to the other guide means and having gates for deflecting cans from one formation line to the other to shorten the cooking period of the cans of food, and perforated pipes within the receptacle and extending along portions of the path of travel of the cans for heating the food within the cans.

In testimony whereof, I aiiix my signature.
