This invention relates to improvements in continuous cookers.

It is one of the objects of the present invention to provide a continuous cooker havmg air an charge valves for charging cans into the cooker and discharging cans therefrom.

A further object of the invention is to provide a continuous cooker in which jets of air, water or steam are used to'force the cans into the cooker and to discharge the cans therefrom.

A further object of the invention is to provide a continuous cooker in which the air and steam pipes are positioned within the axial portions of the caniinlet and discharging valves.

A further object of the invention is to provide a continuous cooker which is of simple construction, is strong and durable and is well adapted tor the purpose de-.

scribed.

With the above and other objects in view, the invention consists of the improved continuous cooker and its parts and combinations as set forth in the claims, and all equiv.- alents thereof. I f

In the -accompanyingdrawings in which the sameyreference characters indicate the same parts in allof the views:

Fig. 1 is a top view of the improved continuous cooker; l Fig. 2 is an end view thereof, parts broken away and other parts being shown in section to illustrate interior construction;

Fig. 3 is an end view of the cooker;

Fi 4-. is a'to view partly in sectlon, of the discharge en rtion of the cooker; and

Fig. 5. is a simi ar view of the chargingend portion thereof.

Referring to the drawing,'the numeral 8 indicates a horizontally extending cylindrical cooker receptacle or drum, which is mounted on supports 9 and is provided with an inlet opening 10 at its upper portion adjacent one end, and an outlet opening 11 at the'lower end portion of the drum, adjacent its other end. Said 0 enings areabove the water level maintains in said drum. The tank is provided with-a rotary carrier 12 formedof spokeds iders 13 (only one being shown) moun on'a shaft 14, and longitudinally extending angle bars 15 which are connected to. the s aced spiders and each bar has one of its ang ed portions extending steam operated inlet and dis- Said bars extend in parallel relation to the shaft of the carrier and are of less distance apart than the diameter of the cans. or food containers 16, so that said cans cannot pass therebetween. The bars meet with a sp rally trending guide track member 17 which is positioned within the drum and surrounds the carrier and is connected to the inner eriphery of the drain. They said guiding memberis formed of metal of T-sha in cross section with the stem portion 1? of the T extending radially inwardly to form a continuous end guide for the cans, while the outer cross section portions 17" form'guides for the side edge portions of the cans. The convolutions of the spiral member are spaced apart a suficient dlstance to to roll on the cross portions an between the stems while being moved by the carrier and advanced by the spiral member. The charging opening 10 is provided with a rotary va ve 18 enclosed in a cylindrical valve casing 19 mounted on the drum. The valve is also of c lindrical form in cross section and closel ts the casing and is formed with radia opening can pockets 20. for receiving cans to be processed. Theupper portion of the valve casing is formed with an inlet 0 eniiig 21 for receiving the cans. Y An inc ined trough 22' extends from a int of supply upwardly to the valve casing and over the drum to form a support for the cans 16 which are fed to the valveby an endless chain 23. Said chain extends in a vertical plane around the drum and is formed with nsverse bars 24 which directly' enga with a ore 25 for receiv a steam pipe 26 having a jet opening 27 in alinement with a w. mt" duct 28 ending to and in communication with the bottom portions of the can pockets 20 to blow the cans out of said pockthe cans. The valve 18 is formed ermit a can ets in successive order when the pockets turn into re ister with the opening 10 of the drum, as c earli shown in Fig. 2. The pocket valve an the steam pi e 26 form" avalve 26', and as each valve poc et turns into registerwith the drum opening 10, its duct 2.8 will move into register with the jet opening 27 and permit the escape of steam therethrough to force the cans out of the pockets and into the rotary carrier 12.

The cans in traveling around the inner e of the drum will be moved endwise by s'd the spiral member" 17 from the inlet open radially, and the other circumferentially. 10 tothe outlet opening 11 of the drum.

A cylindrical valve casing 31' encloses the valve and the drum discharge opening 11 and is formed with a downwardly extending discharge opening 32 through which the cans are discharged. The discharge valve 29 is formed with a bore 32'- for receiving a steam pipe 33 having a jet opening 34 in ls alinement and communication, successlvely,

with radial ducts 35 formed in the valve member and extending from the bore 32 to the bottom portions of-the can pockets 30, so that as said jet opening and ducts come into register, a jet of air from the pipe 33 will force the cans in successive order out of the pockets.

An air or steam jet is also used for forcing the cans from the carrier into the discharge valve 29 and to accomplish this re- J suit, a tube 34: extends into the end portion I the endless chain and'will drop by gravity 1 d inlet valve adjacent the inlet opening of the of the drum and terminates within the carrier and has a jet opening in radial alinement with the discharge opening 11 of the drum. The discharge of air or steam through saidtube coincident withthe can pockets registering with the discharge opening of the drum, is controlled by a valve 36 i and actuated in timed relation to the pockets by a cam member 38. The cam 38 is mounted on and driven by the shaft 39 which rotates the discharge valve 29. A shaft 40 rotates the inlet can valve 19 and both shafts have a cared connection 42 with a driving shaft 41 journaled on the drum. Said driving shaft 41 also has a geared driving connection 43 with the carrier 12 within the drum, and the geared connection 42, and is provided with pulleys 44: for belted connection with a source of power. A shaft 45 geared to-and extendingv from the geared connection 42 t0 the opposite end of the drum, is provided with a chain wheel 46 for drivingthe feed chain 23.

Steam is supplied to the drum through pipe 47, and water by pipe 48. A gauge 49 m icates thelevel of water within the drum.

In use the drum is part1 .filled with hot water and steam is supplie to the drum to ma ntain the temperature desired. ,The cans of; food are now fed into the inlet valve by into the pockets of the valve, and the sai valve in rotating will carry them into the drum. When each can insuccessive order isv in register with the drum inlet opening, the can willdrop by gravity into the carrier, and

. to make amore positive feed jets of steam,

air or water are directed 'ainst the cans to force them out of the poc ets in successive .steam, water or air in addition to gravity will cause the cans to drop from the carrier into the pockets of the discharge valve and said valve in rotating will carry the cans to the discharge opening of the discharge valve.

Upon arriving at this point, t'ne cans will drop out of the pockets by gravity and will also be forced out of the pockets by the jets of compressed air or other fluid under pres- I sure.

I From the foregoing description, it will be seen that the cans are forced into the drum and carrier by steam or other fluid pressure and are discharged from the carrier and the drum and the discharge valve by steam, Water or air'under pressure. In feeding the cans into or discharging the cans from the drum, the valves prevent the loss of any material amount of the heating medium within the drum. The material within the cans is cooked while the cans are passing through the drum, and the'degree of cooking can be controlled by the speed of travel of the cans through the drum and the amount of hot water within the drum so that the cooking operation is a continuous one and that the cans may be fed to and discharged from the drum continuously.
