process throughout a portion of the period of sald rotatlon. and then a cooling process throughout another portion of the period of rotation.

It is another object of the invention to provide a cooker-of the character indicated "herein the cans may be automatically fed into the chamber without substantial shock and automatically discharged therefrom after cooling.

it is also an object to provide simple and efficient means for automatically feeding a charge of cans into the chamber and discharging the same therefrom.

It is still another object of the invention to provide simple and eiiicient means for subject ing the groups of cans to successive cooking and cooling processes in the same chamber;

It is still a further object of the invention to provide a cooking and cooling chamber so constructed and arranged that the force of gravity may be used to effect the passage of the therethrough, and endwise, and

a simple and effective means provided for automatially closing and sealing the chamber at predetermined intervals.

FigureT-is a section on line 77 of Fig ure 6.

Figure 8 is an elevation of a portion of the cooker on the end opposite to that shown in Figure 1 and illustrating the tripping means for releasing the cans to enter the chamber. Referring now more particularly tothe drawing, 1 show at 11 a pair of standards in which is revolubly mounted as at 2 a tubular shaft 8 fitted with a head at near one end and engaging a nonrot-ating tube 5. Axially mounted in the shaft 3 to rotate therewith is a smaller tube 6, this tube also communicating with a non-rotating tube as 7 sothat the parts 3 and'6 may rotate and yet receive and discharge fluids as hereinafter set forth. The other end of the shaft near its standard 1 is also fitted with a head as 8 and a center tube as 9, and this'shaft and tube are connected to non-rotatin tubes as 10 and 11.

Each reference character 12 indicates a tubular chamber mounted upon an annular support 13 which is in turn mounted upon the shaft 3 to rotate therewith. Each chamber 12 is so positioned upon the support 13 that its axis lies in a horizontal plane when in its uppermost position during the rotation of support 13 and also when in itslowermost position, but is at the same time angularly positioned relative to the vertical plane in which the aXis of the support lies and therefore assumes an angular position relative to r a horizontal plane when between, the two extreme positions mentioned. from the uppermost to the lowermost positions-the chamber passes through the position of greatest angularity relative to a horizontal plane as 14;, a suitable angle being selected that will permit cans to slide easily therethrough.

Near each end of the chamber 12 is formed a recess as 15 and 16 having valve seats 17 rected and oppositely acting gate or valve memberspositioned in their respective recesses 1"16'and mounted upon a shaft 23 lying outside of the chamber 12 and parallel therewith and passing through the housings 19-20. One end of the shaft carries a pin 24 at an angle thereto, and the other end has an arm 25 mounted thereon carrying a terminal pin 26 extending laterally therefrom.

' The valve 21 has a hub portion 27 fitted with In its passage a pin 28 which engages a slot 29 in the shaft 23, the said slot being directed toward the adjacent end oi? the shaft and having a short portion as 30 lying at right angles to the axis of the shaft. A spring 31 is inserted between the hub 27 and the side of the housing 19 adjacent the end of the shaft. The valve has a hub portion 32 fitted with a pin 33 which engages a slot 3 1-, in the shaft 23, the said slot bcinil. directed toward the adjacent end of the shaft. A spring 35 is inserted between the hub 32 and the side of the housing 20 adjacent the end oi? the shaft. The result of this eonst ruetion that when the *alves are closed upon seats 17 and i8 and, the shaft 2?) is rotated mantra-clochwise the pins 2S;-l 'l move in the slots and permit the springs to unseat the val ves the continued rotation Oil: the shalt turning the valves back into their respective housings so that the chaml'ier 12 is clear for the passage of cans. When the shaft again turned clockwise the pin 28 first moves along the edge 30 so that no movement is imparted to valve 21 but the pin 3?) advances the valve 22 a little ways into the chamber so as to form a stop for the cans admitted to the chamber 12. Further rotation of the shaft carries both of the valves into the chamber to center over their respective seats whereupon the slots function to force them into engagement with the said seats the positions of the pins in the slots in this last position being indicated at 36 and 37 respectively.

The cooking is effected by means of steam admitted through tube 9. 'Communicating with this tube is a conduit 38 comn'nmicating with an annular tube or conduit 39 lying in substantially the plane of the adjacent end of the machine. From this annular conduit the steam is led to chamber 12 by means of a short tube 41-0 titled with a val ve 4-1 the stem oi which is litted with a cross handle 42. The steam enters one end oi. the chamber at 41-3 and discharged at it through :r'cmuluit 45 parallelling the chamber 12 to a poi ut adjacent conduit i-lilwhere it is titled with a valve 4:6 and disclnn'ges into an annular conduit -iiT. The annular conduit 4i? communicates with the hollow shaft 2 by means oi? a conduit 48. W hen the valves 4;1-i(3 are open and the chamber 12 in closed a continuous flow oi steam passes therethrough, but the valves may be closed to permit the use of a cooling fluid. Stop

pins

49 and 50 mounted on stand ard 1 are positioned to engage the cross handle 42 of valve 4&1 andat the same time the handle 51 oil. valve 4:6 to open the same, and other steps are pe. ioned as at 52-53 to close the same. These stops are indicated in dotted lines in Figure 1 clearly showing their positions relative to the other operating parts hereinafter described.

The cooling under pressure -is effected by means of water admitted into chamber 12 and dischargml therefrom in a manner similar to hat ust described. The Water enters through tube 6 and a conduit 5% to an annular conduit 55 from which it is conducted to each chamber by aconduit 56 titted with a valve 57 having a handle 58. Entering the chamber at 59 it is discharged at 60 through conduit 61 fitted with a valve 62 having a handle 63 and into an annular conduit Get. A conduit 65 connects the annular conduit 6% with the discharge tube or shaft 2. Stops 66 and .67 are mounted on standard 1 to engage handles SEE-63 to open the valves and permit Water to flow through the cham er, and stops 6869 are provided as shown to engage the handles and close the valves. By means oi? this arrangement the stops ail-50 first become eii'ective to open the steam line for cooking, and subsequently stops 52-53 become operative to close the steam line, followed in'imediateiy by the stops G66"l' becomin eti'ective to open the water line for cooling and stops 6869 for subsequently closing the water line to permit discharge or the treated cans and the re ception of cans to be coolzec. It is obvious, of course, that the several steps may be inserted at any desired points in the path of travel of the valve handles to secure the most eliicientresults in adn'iitting and discharging the cooking andcooiing fluids.

In order to operate the shai't23 and secure the timely opening and closing of the valves 21-22 in the chan'1ber12, I provide a cam surface at 70 so positioned as to engage the pin 26 on arm 25 at the time when the chamber is approaching its position of greatest angularity and rotate the shaft until the valves are open and the cans discharged. In order to accomplish the desired rotation of the assembled chambers I mount an annular rack 71 on one end thereof, and mount a mutilated pinion 72 in engagement with the rack to drive the same. The teeth at T3 rotate the chambers far enough to move the arm 25 to the substantially horizontal position shown in Figure 1 thereby swinging the valve 22 back into the. housing 20 and permitting the discharge of the cans. hen the teeth 7% again rotate the device a distance the pin 26 engages cam surface 75 and is carried downwardly a. distance thereby partially closing the valve or gate 22 heretofore described. The rotation again stops while the chamber is being filled with cans, the further rotation carrying the pin 26 over the lower end oi? cam su1'i'ace75 thereby completely closing the valves 2l22 in the chamber 12 and opening the next chamber for the discharge of cans thereliron'i.

It now remains to describe the means TFO! introducing the cans into the chamber. For this purpose I provide a tubular magazine 76 having a rocker arm 77 mounted on its under side and provided with upturned ends 78-79, a spring 8 being inserted between the outer end of the arm and the magazine as shown,

i 81 and tilt the arm 77. Tilting the arm '1" normally lying in a vertical position, is rotated through the positions 82 and 83 to the position 84 so that it will engage the spring 7 withdraws its forward'end from the maga zine and allows the cans therein to slide down into the chamber 12 while its upper end enters the magazine and prevents other cans from sliding in. As the chambers 12 are rotated further and the shaft 23 rotated to close the valves 21 22 the end pin 24 snaps ,oii' oi the spring 81, thereby permitting its forward end. to enter the magazine andiorm a stop for the cans now permitted to slide into the magazine.

The operation of the machine may be summed up as follows, following one chamber from the moment it has been filled and closed. First, the steam is admitted to the chamber for a period of time suhieient to elect the desired cooking and then shutjoi'l' in the manner described. Then water is passed through the chamber for any desired period or time and then shut off as described.

The arm 23 is now actuated by the cam surface thereby completelyopening the chamber 12 at both ends and at the same time posi-- tioning the pin 24 ready to trip the device holding the cans in the magazine. The chamher having been at rest long enough to discharge the cans it is moved forwardly a distance and the arm 23 rotated clockwise a distance by cam whereby partially closing valve 22 and tripping the arm 77' to empty the magazine 76. Further rotation of the chamber 12 eil'ects the complete closure of valves 21-22 by cam 75, and one complete cycle hasbeen completed.

It may now beseen that I have provided a cooker whi-uiein a number of cans may be.

treated at the same time, the capacity of the machine being determined by the'length of each chamber 12 and the number of chambers arranged in circular -formation as described, as well as the speed at which the machine is operated.
