To all whom it my mama:

Be it known that I, AIs'TON MILL, a citizen of the United States, residing at Cincinnati in' the county" of Hamilton and State of Ohio, have invented certain new and useful Improvements in Apparatus for sterilizing Canned Goods, of which the following is a specification; 1

My invention relates to an improved apparatus for. sterilizing canned goods. One of the objects of my invention is to provide an apparatus whereby canned goods in hermetically sealed packa 'e's, preferably cans, can be continuously f into and out eta closed chamber, Sub ec'ted to theac'tion of steam or heat during its travel throu' h the chamber, with means for continuous y rotating or :revolving the cans during their course of travel through the chamber.

Another object of m invention is -.to provide means for lateral y agitating the cans during their 'course of travel throughthe 80 course.-

chamber. a

Another object of my invention-is to-provide a sterilizing apparatus,having a sealed, steam orheating-ehamberwith anmner cylind'er upon whiehthe cans travel durin a portion of their travel-from the inlet to he outlet,: and a series of bars between which the cans are vfed and carried in a spiral Other features of my invention relate to special details of construction,"more fully set' lorth in the description of the accompanylng drawings -forming a part of. this specification, in -w ich': I 3

-To move the cans from one end .of-the cylinder 1 to the opposite end in the spiral groove-way 6, the rods are rotated carrying with them the cans, permitting of a continuous feedinto and out of the cylinder 1. These rods are carried around the inner cylin-der," as follows :-10, 11, represent gear Wheels fined to or formed integral with the I wheels 7, 8, respectively, meshing with pinions '12, see Fig. 4, the pinion meshing with gear. 11, not being shown in the drawings; said pinions being fixed to shafts 13, 14,

which project through the stufling-b'oxes 15,. I

To accomplish this,

suitable valve mechanism is emp oyed and controlled'by the main driving shaft,- whereby the action may be continuous and intirne movements with the b'ars within the c'llnder,- so as to feed each can between the ars.
