- Sprocket chains" 1 wand m "are. trainee-bier the horizontally aligned sprocket wheels 04 and I02 in such a manner as to be positioned in driving engagement with the sprocket wheels 60 mounted on the upper ends of the rotary shafts 53 of the various agitating stirrers in said receptacles 22. In order to hold and guide the sprocket chains I06 and I! in driving engagement with the sprocket wheels 60, a series of idle sprockets I 08 are mounted on shafts I09 which are bolted to the shelves I6 and I? by means of nuts or the like H0 and spacing studs II I are provided for receiving said shafts and maintaining the idle sprockets in spaced relation from the bottom walls of the respective shelves It and II. The idle sprockets are positioned in back of the sprocket chain I07 so that when the receptacles 22 with the cover plates 44 are positioned on the platforms 20, the sprockets 60 of the stirrers will be pressed into engagement with the sprocket chain I01 and into driving engagement therewith. As the receptacles are inserted and removed, the sliding bearing block 99 and sprocket wheel I02 will move inwardly and outwardly to compensate for the lateral chain movement and thereby maintain the sprocket chain I01 in tight driving engagement with said sprocket 60 to cause the rotation of the stirrers in the various receptacles 22.

In operation, the motor 83 is connected to a suitable source of current so that the drive shaft 86, worm 81 and vertical drive shaft 19 will be driven at a constant rate of speed. Upon rotation of the vertical drive shaft I0, the sprocket chains I06 and I01 will be driven in the same direction and the receptacles 22 may be positioned on a platform 20 With the closure member 44 in place thereon so that the sprocket wheels 60 on the upper ends of rotary shafts 53 in said closure members will be drivingly engaged by the sprocket chains I 06. It is to be noted that receptacles 22 may be inserted and removed from the agitating machine on opposite sides thereof with ease and facility and that the stirrers of the various receptacles will be operated in unison. By reason of the unique construction, one or more of the receptacles 22 may be removed from the agitating machine without disturbing the agitating operation of the remaining receptacles and that receptacles 22 of various sizes may be employed by altering the size of the closure member 4:3 and the paddles 51 and employing rotary shafts 53 of the same size as used for other receptacles.

In inserting and removing cans or receptacles 22, it is simply necessary to operate the finger piece 36 of the clamping cam 3I so as to move the cam away from the base 37 of the receptacle 38 and permit the removal of the same away from the base-engaging lugs or members 30. The cabinet structure may be of any height desired with as many shelves and sprocket chains as needed to accommodate a large number of receptacles 22 fitted with the stirrers 53 and 51 with the sprockets 60 thereof positioned for engagement with the sprocket chains I06 and I01.

It is to be understood that the form of the invention herewith shown and described is to be taken as a preferred embodiment of the same and that various changes may be made in the shape, size and arrangement of parts without departing from the spirit of the invention or the scope of the subJ'oined claims.
