Be it known that I, ALBERT R. THOMPSON, a citizen of the United States, residingat San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Cookers, Coolers, and the like, of which the following is a specification.

My invention relates to that class of machines and apparatus used in the canning axis and ooacti'ng with the fixed rail to supand mounted in the receptacle ends.

port the cans and efiecttheir travel in a helical path from their point of entrance into the receptacle to their point of discharge therefrom. Examples of these machines are those known as cookers in which the canned goods are heat-treated; "and those called coolers in which the previously cooked canned goods are subjected to a lower temperature to cool them.

In these machines, accepted constructive practice, in respect to the reel member of the can-track, is to provide a single shaft constituting the driving axis of the reel, said shaft extending the full length of the reel AS such machines are usually quite long and the reels occupy substantially the entire length of the receptacle interior, it has been found somewhat difiicult to arrange. braces which will give the reel sufiicient rigidity, chiefly because the long,'through axis shaft presents .an obstruction to efi'ectivebracing members.

@ne object of my present invention is to provide an eiiiciently rigid reel member of a can-track of the type mentioned, as will be hereinafter fully described.

Furthermore, in machines of this type the common practice has been to carrythe fixed helically directed rail-member of the cantrack, upon a series of longitudinal stringers supported in the receptacle and spaced from its wall. I have found, however, that a simpler construction is to bolt or rivet said rail memberdirectly to and against the wall of the rece tacle in which case said receptaole must 0 course be of circular cross seccooxm, ooonan, Ann THE LIKE.

' tion. But this presents a ditliculty of drainthe case of cookers, which require the inclusion within the receptacle of a steam-pipe for heating the water, the disposition of the helical rail directly against the receptacle wall, leaves no room for the steam pipe, which must, necessarily, be outside of the sphere of rotation of the reel member of the can-track.

Another object of my invention is to provide means by .which the receptacle in which the fixed rail is disposed directly against its wall, may be fully drained and may also have a space or chamber for the inclusion of a steamrpipe. I

With these ends in view my invention consists in the novel cooker, cooler, or like machine for treating canned. goods, which ll shall now fully describe by reference to the accompanying drawings in which- Fig.1 is a longitudinal, broken, section,

. partly in elevation, of my improved machine "or apparatus.

will be presently mentioned. The receptacle is provlded with an inlet indicated at 9 in Fig. l, and an exit, indicated at 3, for the canned goods which pass through it.

Within the receptacle and bolted-or riveted directly to and against its wall is the fixed rail 4. lhis rail, which is preferably of T- section with its leg portion extending inwardly is helioally directed throughout substantially thelength of the receptacle, and forms one member of thecan-track. The other member of said track comprises an annular series of spaced rails 5, preferably of angle section,'lying and revolving withm the fixed helical rail 4, in such relation thereto that the cans are carried and supported between the rail 4 and rails 5, the latter being parallel to their axis of rotation, whereby the can path is a helical one throughout the length of the receptacle, all as is now well knownand common in practice. 'The ralls 5 form the periphery of a reel which n myr bolt to the reel-rails comprises b aces sha present improved cross plates 6, short 8 and torsion brat; are fixed in the hubs and said shafts jot suitable bearings l-O tacle l. ihS illust the reel, 1

between the plates 6, the diagonal torsion orac es 9.

The bottom of receptacle 1 is formed with a longitudinally extending communicating chamber 13 of any suitable shape in cross section. A practical way of making this chamber is to distort the receptacle walls from the circular to a downward convergence as shown in Fig. 2, thus giving it a V-shape. This chamber opens dlrectly into the interior of the receptacle, and the coils of the helically directed rail 4 span its width over its top. The ends of this chamber 13 are closed, but into one end is fitted an inlet water pipe 14, and in its other end is a drain 15, ada ted to be closed by a suitableremovable p u -Fig. 1. It will now be seen that, notwit standing the disposition of the fixed helical rail 4 directly against the receptacle wall, all the treating water within the receptacle may be drained out as occasion requires.

In the case of a cooker, where a source of heat must be provided, the bottom chamber- 13, being outside of the fixed rail 4, serves as a means for introducing and housing a steam pipe 16.

In t is connection it should be noted, however, that in its mere function as a housing for a steam pipe, the outlying chamber is not necessarily at the bottom of the receptacle. It may lie along outside of any portionof the circumference of said receptacle and be of advantage as such steam-pi e housing in connection with the prima eature of securing the helical rail" direct y against the inner surface of' the receptacle wall.
