moines.

To all 'whom it may concern:

Be it'knownthat I, ALFRED Jol-IN Knixs'r, a citizen of the United States, residing at Campbell, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Cookers, of which the following is a specification. y

My invention relates to the class of cookers used'in the canning art.

Machines of this class are characterized, in general, by an outer casing with means for heating it, and means for conducting the lled and capped cans in an extensive course through the casing, said course being, in accepted practice, such as is consistent with compactness in the machine for the sake of economy in floor space, and of a nature that will provide for rolling the cans as they travel through their course.

The object of my invention is to provide for these essentials in .a simple, compact, and effective machine, and to this end, my invention consists in the novel cooker which I Ashall hereinafter fully describe, b'y reference to the accompanying drawings, in which- Figure llis a broken top plan of my cooker. Fig. 2 is a vertical sectional view of the same, partly in elevation, 'the sectional portion being taken on a radial line from the center to the driving shaft 17. Fig. 3 is a perspective view of the tier or vertical series of Hoor-plates, together with the overlying can-pusher-frames, thev view point'being below, in order to show the receding progression of the discharge openings in said floor-plates. Fig. 4 is a fragmentary view taken in a vertical plane through the. discharge openings 32 of the lowermost floor-plate.

1 is a foundation plate, havin@ a pan-like shape, to serve as a receptaclel seal 2. Into this plate is inverted the casing 3, which may, when required, be readily lifted off to afford access to the interior parts. From the plate 1 rises a fixed column 4 its upper end projecting through the top of the casing.

Mounted on the column 4 are the ioorplates 5 invertical spaced series, saidfloorplates being non-rotatable and fixed to the column in suitable manner as, for example, by the set screw G,binding the plate hubs j, as shown -in Fig. 2. I have here shown seven of these,floor-plates, though there may Specification of Letters Patent.

be a greater or less number as desired. Above each floor-plate is a can-pusher adapted by its rotation to roll the cans upon the plate. Each pusher is, in its best form, a skeleton or open-work frame composed of a hub S, a rim 9, concentric spaced rings 10 disposed between the hub and rim, and radial bars 11 between the rings, thus dividing each plate into a multitude of open can-re ceiving pockets 12. As seen in Fig. 1, there are here illustrated three concentric annular series of these pockets, those of the uppermost pusher-frame only being shown in thisv figure. These pockets lie between the @rter rim 9 and the several rings 10, and said pockets in order to have the proper area to receive a can and be equal in size, are necessarily out of line radially, so that the bars 11 ofthe three series are not continuous radially. Though I have here shown three annular series of pockets for each pusherframe, this number may be varied aocordin?r to the size of the machine. A

Fach pusher-frame is mounted to` rotate about the column axis of the machine. The mounting here shown illustrates a simple and convenient construction, and comprises ball bearings 13 under the hubs of the pusher-frames, seated in raceways on theA floor plates, and wheels 14 under the rims of ytheJ pusher-frames, running on said floor plates. 'Io drive the pusher-frames, I here show teeth 15 on the rim 9 of each frame, with which mesh gears 16 on a vertical shaft 17 having a worm pinion 18 on its lower end. With this pinion engages a worm 19 on a drive shaft 20,4 carrying the pulleys 2L Outside the casing at one side of the upper portion thereof is fixedV and suitably supported yindependently of said casing, the

outer feed runway 22, which for the machine here shown, is a. three-part one. This runway is slightly inclined as shown in Fig. 2, to enable the cans to roll by gravity. The inner. end of the outer runway stops short of the casing, as seen in Fig. 1, so that said casing may be removed without interference from the runway. The runway at its inner end leads directly to the entrance opening 23 inthe casing; and inside the casing,

and supported by a bracket 241, from the column 4, is the inclined inner runway 25, the outer` e'nd of which lies at the entrance opening 9.3 of said casing and near enough to the outer runway to enable the cans to I iatenteaauiy 2i, inra. Application led December 1, 1913. i Serial No. 803,910.

roll directly from one to the other.v The inner end of the inner runway lies just above the series of pockets 12 of the uppermost. pusher frame. In the uppermost floorplate, on a radial line just back 'of the line in which said floor-plate receives the `cans from the inner feed runway 25', are the discharge openings 2G, shown in dotted lines in Fig. 1. One of these openings is shown more clearly in Fig. 3.

In: the next floor plate, below the uppermost, and just back of the discharge openings 2G in said uppermost floor plate, are the discharge openings 27, also shown in dot-ted lines .in Fig. 1. In Fig. 3, one of these openings 27 is clearly shown. In similar succession, or, as it may be termed, reced-` ing progression, the several floor plates are provided respectively with the discharge openings 28, 29, 30, 31, and 32, the latter being 'in the lowermost floor-plate. Under these last named dischargeopenings 32, is the inner discharge runway'33, which leads to the exit opening 34: in the shell, outside of which is the outer discharge runway 35. The receding progression of the several discharge openings is shown fully in Fig. 3.

36 are annular steam pipes in the spacers between floors, 37 is the manifold steam supply pipe, and 38 is a steam pipe in the water seal 2.

Cans 39 are indicated in dotted lines in various positions in connection with the cooker. l

The operation is as follows: The cans roll down the outer feedl runway 22 and into the machine through'its entrance opening 23. Continuing, they roll down the inner feed runway 25 and are delivered into the pocket-s 12 of the uppermost pusher-frame, and they rest on t-he uppermost licor-plate 5. This pusher-frame, rotating in the direction of the arrow shown in Fig. 1 and Fig. 3, causes the cans to roll on the floor-plate 5, throughout. nearly a complete circle, that is, to the discharge openings 26 in said floor-plate.

Through these openingsthey drop down asl indicated by the arrow in Fig. 3 into the pockets of the next pusher-frame below and rest on the second hoor-plate. By this second pusher-frame they' are rolled around on the second floor-plate, until they reach the discharge openings 27 of saidfioor-plate. Through these they drop' as indicated by the-arrow in Fig. l3; and in like manner they are carried around by succeeding pusher-frames on. succeeding floor-plates, dropping successively through the discharge openings of said licor-plates all as indicated by the arrows yin Fig. 3 until finally they drop through the last discharge openings 32 Yinto the inner discharge runway 33, and

thence they roll out through the exit opening 34 of the casing to the outer discharge runway 35 by which they are carried to their destination. It will be seen that by this ar.- rangement o-f thefeed and discharge runways the casing-3 may be lifted off without interference,'- and, further, that by the inversion of the'casing in the pan-like bots tom ,plate 1, a 'water-sealis possible consistent with the.l free joint of said casing with said plate.
