To all who'vri 'it may concern:

. chine embodying a sterilizing chamber that "necessary, and is consu1ned,to properly heat.

Be it known that I, JOHN JnNNiNGs, a

Greenwood, in the county of Johnson and State of Indiana, have invented certain new anduseful Improvements 1 in Agit'ating Cookers and Processors, of which the' following'is a specification. I y v This invention relates to an agitating object of! the invention'is to provide a ma- -a capable of receiving and sterilizing 'alarge number of cans, thereby giving the machine a large working eapac'ity,thisbeing of u'tmost importance, since considerable time is the product within-the cans by bringing it to the desired temperature to effect thenecessary sterilization to destroy ,terial development and growth. I

A further obj ect of the invention is to provide means for supporting the cans on their. sides and rolling them through the cooking chamber to brin the contents successively above the axes of the cans,and by-arresting the movement of the cans at intervals, 'to permit that. portion of the contents carried upward by the movement of the cans to settle bank, allof the contents of each can will future bac- -finally. be brought to the surface. 4 A further obj ectof the invention is to provide a cooker which will afford suflicient travel for the cans between the inlet and outlet valves to in ire the'cohtents of the cans to be perfectly" ri-l'i'zed before the cans are discharged from the cooker. I

A further object-of the 'in'vention' is to pro vide a cooker for sterilizing canned goods which is provided at intervals with pipes which inject jets of steam to play upon the cans as they roll' through the cooking c'hamber. i

The further object of-this invention is to mount pn'e of the shafts'and ad rector to change the direction of the movement of the "cans so that they move in unison, in order that the tension of the chains carried by the spi'ocl cet wheels on the shafts may be ad- -cookei' for sterilizing canned goods; and the thereof in plan an'l a p justed Withoutidisturbingthe relative position of the directortherctoy citizen oftthe-United States, residing at 'Figure 1 is a fragmentary detail View of .55

T his frame is preferably composed of sheet steel, and

forms an inclosure or chamber 111 which the canned'product is'sterillzedg. This frame is provided with/suitable supporting legs 2.

A shaft Pis mounted in each end of the X body 1,. and extends .tra'nsversely through the sterilizing chamber. \Each of. these shafts carry a plurality of sprocket-wheels 5, which are keyed thereto and revolve therewith.- A sprocket-chain 7 connects a' sprocket wheele on each of the shafts 4', so

that when" one shaft is operatedmovement will be imparted to the other. The 'links forming the sprocket-chains 7 are of a length equaling the diameter of the cans,

and the links comprising the oppositely po sitioned chains: are divided. in groups of pairs which are tied together by. the rightangle plates 10. These plates are'rigidly se cured at the. ends with the-l1nks, and the, horizontal portions of the plates 10 form the bottoms of the channels on which the, cans ride while passing through the upper portion of the cooking chamber. The channels for retaining the cans are formed by means of the vertically extending portions of the'plates 10. These vertical extensions of the plates 10 bear against the internal wall of the body 1 so that the open ends of the channels are sealed, so as to prevent the cans from crawling over one another, to 1nterfere (with the operation of'the machine. The plates 10 extend transversely and nearly the entire width of the sterilizing chamber,

so that each channel is of considerable length and is capable of carrying a large number of cans to be simultaneously sterilized which, in a measure,- illustrates the large working capacity of the machine. v

To keep the upper portion of the con- "eyer-chains" in alinement when heavily 'ladened with'canned goods, I support said convyer at each link.- These links are provided with the antifriction rollers 12, which See Fig. 4:.

engage the channeled ways 15.

I These Ways are supported by the stay-rods 16 and extend to and engage the frame 1.

To mamtama proper tension on the con veye'r-chains 7 and take up such lost motion as may result from wear, I mount the shaft 4, in one end of the machine, in the. movable journal-boxes 17, and by means of the-screwshafts 18, which engage said boxes and the frame 1, the. journal-boxes may .be moved in a direction to tighten the chains, by means of the hand-wheels 19. To compensate for wthe adj'ustabilit-y'of the shafta, the end-wall 2 3 of the sterilizing chamber is secured to and moves with the journal-boxes 17,-so as 'to keep the relative positions of the sprocketwheels 5 and the end-wall 23 the same.

The frame 1, forming the sterilizing chamber, is provided on its upper and. lower surface with an inlet and an outlet aperture 20,

through which the cans pass into and out of the machine. These apertures are located,

with relation to each other as to afford the cans the greatest amount of travel through the chamber, and thereby insure that the canned product will be thoroughly sterilized before it is discharged from. the machine. Thecanned product is preferably sterilized .by subjecting the cans to jets of live steam which will play upon the cans while they are passing through the chamber. The steam is fed into the chamber through numerous pipes 24:, which are located at convenient points along the side-wall of the sterilizing chamber.

In or'der'to sterilize a large number of cans with regularity and despatch, and re duce as much as possible the necessity for manual labor, I provide a device at the inlet and outlet apertures of the sterilizing chamber which, will introduce and remove cans .into and out of the machine. This device izin driven.

' ber'.

consists of a cylindrically shaped drum 25,

which is suitably supported in a segmentally This trough is secured a chain of pinions, one of which constitutes the idler pinion 32 which meshes with the pinion 83, secured to the end of the shaft 1, and by which the conveyer-chains 7 are The pinion 33 meshes with a corresponding pini'onBl securedto the shaft that drives the discharge device, which. removes the cans from the. sterilizing chamber. This chain of pinions, namely 31, 32, and 3et, together with the mechanism thcydri-vc, which include the feed and discharge devices and the conveyer-chains 7, are given an intermittent movement received through I the mutilated pinion 38, which is mounted on the shaft 39. The shaft 39 also carries the pulley 10, and by means of the belt. ll which leads to a suitable power source, the mutilated pinion 38 is given a slow continu-' ous movement, and through its periodical engagement with the idler pinion the movable parts are given an intermittent movement, as above pointed out. Each movement so imparted to the feed and discharge de'vices'is sufficient to give each device enough rotary movement to bring one of the lol'igitudinally extenting can-receiv-- ing channels :28 therein into registration with the inlet and outlet aperturesso that a series of cans will. simultaneously be introduced into and removed out of th sterili ing chamber. The movement between the feed and discharge devices and the c'onveyer is so timed thatwhile the devices are introducing and removing the cans the conveyer will have moved forward a sufiicient'dis'tance to bring a channel on the conveyer, formed by the vertical extensions of the right angle plates 10, beneath and above the inlet and outlet apertures 20 n the sterilizing chamthe cans from the machine, but they also form valves for closing the inlet and outlet apertures 20 so that the steam, which is employed for sterilizing thecanned product and is under pressure within the chamber cannot escape.

I prefer an intermittent movement especially for the conveyer, for the reason that The cylindrica drums '25 and the troughs 26 not only introduce and remove with an interruption in the movement .of the "cenveyer andthi-i with each pulsation of Increment whiclrurges the conveyer forl the contents ofthecans will be agid, or, in other words,'shift ed about, so ithe entire bulk in-each can is thoroughly 'isthe end sought. ,I' am aware that cans-containing food have been supported on their sides and have been rolled continuously through a cooking chamber, asshown for example in Patent x0. 498,358 to Men-n1- & Lovell.

termittently through the cooking chamber,

but in neither'case is ,the can rolled to bring different portions'of the solid contents sues cessively to the periphery of the bulk, and this intermittent travel of the cages and crates does ndt mix the contents of the cans;

I 'have found by experiencethat by supthem through the cooking chamber, brings all of the contents of the can successively above the axis of the can, and that by arresting the cans movement at intervals, permitting. that portion of the contents carried upward by the movement of the can to drop, a thorough mixing of the contents. of each can is ultimately accomplished.
