Carried on each endof the shaft 14 is a large bevelled gear 2% which operates in opposite directions a small upper bevelled gear and a corresponding lower bevelled gear 26. The bevelled gear .24: and the bevelled gears 25 and 26 are enclosed in an enlarged extension 27 of the casting 13 at either end of the horizontal portion thereof. rihe bevelled car 25 is ri 'id ontheshaft 28 near the upper end thereof while the bevelled gear 26 is rigid with the sleeve 29 which is loose on the shaft 28. The shaft 28 extends ver tically throughthe enl ed extension 27 and is rotatable in appropin e bearings 30 in the extension 27 and the outer closure plates 2Za thereof The shaft 28 has pairs" of spaced radial mixer blades or agitator fingers 31 or its lower end, the uppermost and lowermost blades or lingers 31 being of uniform len th and'slightly shorter than the iuterined blad s or fingers 31. T he free ends of all the blades or fingers 31 are bevelled to describe an arc. Working between theblac gers 31 are the inwardly directed b lingers 32 which are carried on the is: opposed branches of the oval Irame 33,

As the col'istruct ion of the device has thus beenrdescribed 1n detail, brief reference is "now had to its use and 'modus operandi:

The beater or mixer maybe employed for heating or mixing the contentsof two sepa-.

rate containers simultaneously orjin a single container, if desired. In the latter case, the device will be supported entirelyfwithin the container by the foot 7 resting therein. In the former case, the foot 7 would rest on the stationary support between the two containers and on which, the latter may also rest.

In either case the two beater structures are simultaneously operated by the single operating shaft simply by pressing repeatedly on the head or knob 22. This operation as sures. opposite rotation of the bladesor fin gers 31 and theco-operating blades or fingers of said large gears;

signature.

32 of each beater or mixer structurethus assuring thorough agitation of the contents of the vessel or vessels, as the case may be.

From the foregoing description taken in connection with the accompanying drawings, it will be manifest that'a heater ormixer is provided that will fulfill all the necessary requirements of such a device, but as many changes couldbe made in the above description and many apparently widely different embodiments of nay-invention may be constructed within the scope of the appended claims without departing from the spirit or scope thereof, it is intended that all matters contained in the said accompanying specifi cation and drawings shall be interpreted as illustrative and-not in a limited sense. 7

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. .A device of the class described including a transverse shaft having a central crank portion; gear wheels mounted on the opposite ends of said shaft; double beater members arranged outwardly of said gear wheels and driven thereby; reciprocating driving means extending upwardly from said shaft and connected with the central crank portion thereof; enclosing and supporting means for said shaft, the gears carriedthereby, the double beater members and the central driving means for said shaft; a resilient central support for said last mentioned means; and means totresiliently retain in normal unoperated position the central driving means for the said shaft. 7

2. A device of the class described including a horizontal crank shaft having a central crank portion; large gears mounted on the opposite ends of said crankshaft; a casing for said crank shaft and said largegears with an upstanding central.,portion; a reciprocating operating member in the upstanding portion of said casing; a link connection between said reciprocating operating member and the central crank portion of said crank shaft to drive. the latter; means to re siliently retain said reciprocating, driving member in its uppermost position; a resilient support depending from the centre of said casing; a double beater member supported in the outer ends of said casing outwardly small gears for said double beater members meshing with said large "ears; and removable means for closing the outer ends of said casing.

In testimony whereof I hereunto afiix my JOHN WESLEY BELL. [1,. 8.
