Fo ltz, Cleveland, Ohio, assignor to The Mod Qompanm'Cleveland, Ohio, a corporation 7 of Ohio This invention relates to apparatus for storing, agitating and dispensing, as desired, differ- .ent characters of paint or similar material, whereby any desired mixture may be readily obtained. vPoweruactu-atedpaint mixing apparatus herebefore used hasgenerally been of such size asto restrict the use thereof to relatively large users of paint materials, as a result of which, small users have been compelled to resort, largely to hand methods of'mixing materials. -The ,hand method is objectionable not only from a viewpoint of. the time consumed, but also in the lack of assurance of uniformity of .mixture of the material in the individual can. Whenever a can remains unused fora short time, the heavieringredients settle. to. the bottom, and there is a likelihood that the operator may'f'orget to agitate the contents before withdrawing a portion thereof. There is a large demand for a small, compact machine that i will enable the operator to use quart size cans, 1 and to obtain comparable accuracy, and efliciency ,in quality of mixture and inconvenience of han- 'dling as'may be obtained by the large power driv- (en-machine.v 1

An object of ,-the...present invention, therefore,

7 is to provide small sized equipment that will en- .able the use of. quart cans in.-the machin and that will efiect simultaneous agitation of the contents in a plurality of cans. .The invention additionally includes aconstruct-ionwhich will constitute a compact storage receptacle for the 'canswith provision forIen-abling any can to be selectively removed fordispensing' a portion of the contents-thereof without necessitating removal of the othercans or disturbing their operative connection with the agitating mechanism.. An additional object is to provide a machine by means of which a driving connection is made. automaticallybetween an agitator device and a driving wheel whenever a container 'is interlocked with the carrier therefor.

In the respective drawings, l indicates an upright frame which is shown as a hollow member having a partition H therein, and a cover plate Application March 26,

l2 thereon; .The plates H and [2 are apertured to receive a shaft 13 which is journalled for rotation with respect to the frame and which has afiixed thereto a ,beve1 gear M at the lower end,

, and a driving wheel I at the upper end thereof.

- The wheel [5 is adapted to make frictional engagement .at its periphery with a plurality of driven wheels l6, each of which is supportedfor rotation with-in ahead I'l that is-adaptedto be attached to a can, or "other container, indicated in general at l8- Each driven wheel is attached to,-a-shaft l9 that extends through the associated head I! and carries an agitatorjfl at the lower endthereof.

To actuate the driveshaft I3, I provide a bevel gear 2! thatmeshes with the gear 14,; and is aflixed to a shaft 22 that-is journalled in the frame ID. A hand wheel 23 is shown as being afiixed to the outer end'of the shaft 22. g

To support the various paint containers, I have shown a turntable or car-rier 30 which is supported on the plate l2 and is rotatably mounted tainer, and the connection is made by lifting the assembled head and container as a unit off the carrier as is shown in Figs. 4 and ,6.

To eifect a removable connection betweeneach head and theas-so'ciated container, I have shown a plurality of clamping members on each head,

each member includin a finger 35 which is affixed to a pin 36 that projects through the head and has a tool receiving slot 31 in one end thereof. The finger is adapted to engage frictionally the lower surface of a U-shaped flange 38 that customarily utilized on paint cans for holding a removable cover thereon. In practice, the cover is removed and replaced by the head [1 which is handled as a unit with the driven wheel IB and agitator 20 as aforesaid. Each head also has a spout 40 extending .'thereirom, and additionally,

preferably has a closure 4| therefor which may be swingably mounted thereon by means of :a threaded retaining member 42.

To use the machine of the present invention, the liquid container each having the head and agitating means assembled thereon are positioned on the carrier by moving the sockets 33 into registration with the pins 32, and by then causing the pins to enter the sockets to efiect an interlocking connection therebetween. The diameters of the Wheels l5 and I6 are so chosen that when the interlocking connection is m-ade between the carrier and container head, a frictional driving connection simultaneously"1nade between the driving and driven wheels. Then while the carrier is held in stationary position with respect to the frame It and the hand wheel 23-i-s*-rotated, the resultant action is a rotati of the agitator 20 in each container? During the agitating procs sthe' rier may be held stationary, either by hand or by any suitable stop mechanism one of WhiCh'jJiS illustrated in Fig. 1 as a pin 50 which is movably mounted on a housingpartially indicatedby'th'e broken lines 5|, and which is selectively insert- -Jabl""jiritb"the space between the pins32 fo-r ad- -'-jacez'iii hl'aads' The pin may he manually withgarawn at any time for enabling 'the carrierto' be jtiirn'edflbyliand so as to present any 'desire'd conramer tofthebperator who fmay be standingin 'f'fiont of f'the machine.
