Application filed December 29, 1925. Serial No. 78,253.

My invention relates, in general, to thetreatment of packaged goods, and,' 'in particular, to an improvement in said treatment by which it is possible to run a continuous I procession of packaged goods composed of different kinds, through a single treating etfeet in such relation that the different kinds may be readily segregated upon'the 'completion of the treatment. 4 l Infurther explanation, and as illustrative of my invention, I will refer to' the canning art. It is customary in the canning. of certain food products, for example peas, to initially divide the peas into a plurality of 1 grades, each grade being preliminarily prepared, treated, placed in cans, andthe cans sealed or closed, each grade being so treated, simultaneously and continuously, in its own line of apparatus.- It is desirable, however, at this point in the process .to combine the several, grades for subsequent, treatment,

such for example as cooking, so that all may becooked or otherwise treated in a single line of apparatus, the use of such single line of apparatus, of suflicient capacity to handle allgrades simultaneously, being more economical than the continued se arate treatment of the various grades in individual lines of apparatus of smaller capacity.

not in one apparatus necessarily involves the proper segregation of said grades at the end of'the process, and it is to this end that my present invention is directed. For purposes I of'illustration, I shall confine'inyself to a "description of thecombining and segregation of two grades only, but it will be obvious that the principles involved can be extended to a greater number of grades if desired;

49 and for the same reason I shall describe the combining and segregating processes as applied to a cooking effect, as used in the canning of good products, but it will be apparent that the said processes may be applied with equal facility t6 other effects. It is also -tobe understood that theprinciples of my invention are "not limited to the treatment of canned or packaged goods, but may be employed in the segregation of other 50 classes of objects which are continuously ad vanced in a single line or procession of individuals of different kinds.

It has been suggested, that where identical cans containing two different grades of product are simultaneously fedinto and passed through a 'grade before or while feeding them tothe cooker, but this, even if it were practicable relative positions through the entire path of This combining of several grades of prod member for each receiving means, so timed single cooker, the proper segregation of such cans, at the discharge of the cooker, can be accomplished by the expedient of preliminarily marking the cans of one in the rapid movement of the procession, in-

volves manual attention both in them'arking andin the separation subsequently, such acts being wasteful of time, uneconomical, and not very accurate or satisfactory in results.

I have, however, fdund that it is possible to feed the two grade lines continuously to the single path of the cooker effect in such manner, that the individuals of each line may 7 be automatically and with accuracy sepa rated upon the completion of the cook, and each delivered to its own destination, the operation requiring no manual attention.

My improvement consists essentially in so feeding the two grades to the line or path of the cooker eliect that the individual cans of each grade occupy predetermined relative positions in said line and continue in such said cooker; and at the end of the cook diverting said individuals to different destinations in the same'relative order in which they wereinitially placed in the line. The apparatus by which my improvement is carried out, comprises separate means for receiving the respective grade lines, a single elevator with pockets adapted to supply the cans individually to the cooker; a transfer with relation tothe pockets of the elevator as to depositthe cans of the two lines in predetermined respective pockets; a cooker member having a definite can path through it, to which'path the elevator delivers the cans in continuous procession with the cans of the two grades still occupying their prede termined relative positions and in and through which pathsuch predetermined relation is preserved; and a means associated -with the discharge of the cooker member timed correspondingly to the initial relative positioning of the cans in the line to switch said cans to separate destinations.

For the sake'of illustration, I'have herein shown and described an apparatus adapted to place the individual cans of two different grades in successively alternating sequence or order in the procession leading into and through the cooker, and an apparatus associated with the discharge of said cooker for alternately directing the ind1vidual cans of said procession into two separate lines. It

must be understood, however, that my invention is not limited to such individually alternating sequence in the cooker line, but may include, by a proper and obvious arrangement of, the combining and segregating apparatus, the positioning ofv the individuals of the two grades in any predetermined order or relative position in the cooker line, and the subsequent segregation of said in dividuals from the line according to the same predetermined order. Thusfor example the cooker line may be composed of alternating groups of cans, the cans of one group being fed from one grade line, and those of the next group from the other, and so on, instead of the individually alternating arrangement hereinafter way of illustration. Obviously the segregating apparatus must b-eso timed as to segregate the cans,- whether by groups or-individually, in the same predetermined order as they are fed into the cooker line.

A preferred form of apparatus embodying my invention will'now be fully described with reference to the accompanying drawings, wherein- Fig. 1 is a partly broken side elevation of a single line cooker of well known type having associated therewith apparatus for introducing cans from two sources and for segregating them at the discharge.

ig. 2 is a vertical section, enlarged, of the combining and feeding -mechan'ism.

Fig. 3 is a section taken in the direction of the arrowon the line 33 of Fig. 2.

Fig. 4 is a vertical section, enlarged, of the cooker discharge and can segregating mechanism.

Fig. 5 is a transverse section, taken on the line 55 of Fig. 4, of the segregating disks, and their associated mechanism. i

Fig. 6 is a transverse section, taken on the line 6-6 of Fig. 4, of the segregating disks, the associated mechanism being omitted for the sake of clearness.

F v Fig. 7 is a sectional detail of the mechanism shown in the lower portion of Fig. 4, the segregating disks being advanced through approximately ninety degrees.

In the drawings, and referring for the moment to Fig. 1 thereof, the reference numeral 1 designates a cooker through which the cansare, passed in a continuous single line procession. For punposesof illustration, I have shown this cooker as of a well known type having a helical rail 2 extending around its inner periphery and forming a continuous helical can path along which the cans (not shown) are propelled 15v a reel 3 provided with spaced longitudinal bars 4. said. reel being mounted upon and rotated by a central shaft 5. At one end, said shaft described by carries a gear 6, with which is. associated a drive shaft 7. Suitable means, not shown, are provided for maintaining the deslred temperature in the interior of the cooker.

The continuous can path through the cookerextends from a can inlet valve indicated at 8'to a can discharge valve indicated at 9, so that the cans pass into,-through, and

ont of the cooker in a continuous procession.

The valves may be of any suitable and well known form, and are drivenby any sintable means, as for example a shaft 10' provided with a pinion 11 meshing with the main gear 6. The cans are fed, in continuous processlon,

to the inlet valve 8 by. an elevator indicated" at 12,.and shown in detail in Figs. 2 and 3.

This elevator comprises a trough 13, in

able and convenient means for carrying out this step of the invention,

I have provided the mechanism shown in Figs. 2 and 3. The cans of one grade, indicated in broken lines and designated by the letter A, are fed to the elevator 12 by a gravity chute. 18, Fig. 2. and one such can A is deposited in each alternate pocket or space betweenflights of she elevator chain. In order to prevent the propel the cans up said trough, the

a sprocket 16 engaging oneupon a shaft 17 which is driven inthe proper cans'A from entering the interveningchain pockets, I provide a pair of turrets 19, Figs.

2 and 3, securedupon the sprocket shaft 17,

and formed with pockets 20 corresponding with each alternate pocket or space'of the chain, andwith intervening teeth 21 adapted to enter the intervening pockets or spaces of said chain to exclude the cans therefrom. Thus'the cans A can only enter the alternate chain spaces corresponding to the turret pockets 20, as hown in Fig. 2.

The cans of the other grade, indicated in broken lines by the letter B, are fed, in any suitable manner not shown, through an aperture 22, Fig. 2,to a pocketed turrent' 23,

which timed to deposit them in the elevator pockets or spaces intervening between those occupied by the cans A. sultablv formed guides 24 cooperate .,with said turret 23 in thus feeding the cans B to the elevator. Theturret 23 is mounted upon a shaft 25, which is connected with the shaft 17 by a chain indicated at 26. and said shaft 25 is driven. by a chain indicated at 27, in Fig. 1, from the cooker valve shaft 10. Thus the elevator. and its feed mechanism are driven in the proper timed relation to the cooker valves.

The sources from'which the cans A and B, entering. ,respectively at 1'8 and 22, are brought, is immaterial. The essential point is that said cans are automatically placed upon the elevator in a definite pre-dete-rmined relation, which in this case 1s one of individual alternation, the procession of cansin said elevator consisting of the twogrades,

' A and B, in alternating sequence. This relamechanism is illustrated in Figs. 4 to 7 R6 fer-ring for t e moment to Fig. 4, the movdisks are rotated so that their raised portions 38 come into line-with the can path, the can then approaching. along the chute 28 is able member of the discharge valve 9 is shown as a well known form of pocketed rotary turret 9 which is understood to re ceive the cans successively from the cooker in i the usual manner, and which deposits them, in a procession'and still in their initial sequence, upon a chute 28,'down which they roll by gravity;

The chute 28 extends downwardly, and passes between two continuously revolving disks 32, suitably mounted in a frame 33. These disks are axially aligned, and are secured upon shaft portions 34, one of which is connected by a chain with the cooker valve shaft 10. The relation of said disks andtheir shaft portions is shown in Fig. 5. Each shaft portion 34 carries a gear 36, which are interconnected b a pinion shaft 37. Thus both disks 'revo ve together, although the space between them is clear for the passag of the cans upon the chute'28.

The inner faces of the disks 32 are formed with se mental raised'portions38 at two diametrlcally opposite points. As shown in Fig. 5, said raised portions do not extend to the centers of the disks. and taper "0a toward their peripheries. The sides of said raised portions also taper cit, as shown in- Fig. 6, and their maximum area is bounded by the curved lines seen in Figs. 4 and 7 The raised portions of the two disks are op posite each other, asxshown in Figs. 5 and 6. The normal, or flat portions of the surfaces of the disks 32 are so spacedas to permit the caught by said ra sed portions, as indicated at B in 'Figs. 5' and 7, and is carried up with said disks and deposited upon a chute 39,

Figs. 4 and 7 ,spaced above the lower-p01- tion of the chute 28, and leading to a separate place of deposit, not shown. v

The disks 32'are so timed with relation to the discharge valve 9 of the cooker that.

they make a quarter revolution "for each can discharged by said valve,- so that alternate cans arc'allowedto pass along the chute 28, and the intervening cans are diverted to the chute 39; and they areso timed with relation to the feed turrets 19, and to the length of the can path between said turret-and-said disks, that as each can of grade A approaches said disks, it passes freely between them along the chute 28. and as each can of grade B approaches, it is lifted out of the L procession and deposited upon the chute 39.

Thus the two grades, which are initially combined in a definite pre-determined order or sequence in a single procession, are subsequently segregated, automatically, according to the same order. 1

It is to be noted that any failure to supply either or both grades of cans to the combining feed mechanism will have no effect upon the segregating mechanism, for, in the event of such failure of. supply, the pockets or spaces of the feed elevator 12 into which the absent cans would have been fed will remain empty, and as such pocketscomrnunicats with corresponding pockets in the cooker path formed by the reel rails 4 and the helical guide rails 2, the positions of the absent cans will be held vacant througout the entire can path. That is to say, there is no opportunity for a can to get out of its predetermined position in the procession, even though the adjacent positions he vacant, and

therefore each can will be directed by the passageof a can between them, as indicated at A in Fig. 5. Thus when said disks are in the rotative position shown in Fig. 4, the can A can roll down the chute 28, passing freely between them, and continuing on out to any suitable place not shown. But when said segregating disks to its proper destination irrespective of. its neighbors in the procession.
