Referring now in detail to the drawing, l0 designates a machine embodying the invention. the'same com-prises a stand I I having vertical legs l2 and a top plate l3. The legs [2 may be interconnected by'bracing I4. Below the table top I3 is a horizontal bracket l5 supported by the legs 12. On the center of the bracket I5 is thru t bearing [6 supporting a vertical shaft H which extends up above the top wall Hi. The top wall I3 is formed with an opening l8 through which the shaft l1 passes. Attached to the underside of the top wall I3 is a bearing IS in which the shaft I1 is journalled. Attached to the lower end of shaft H is a, pulley wheel 26. Mounted on the bracket |5 is an electric motor 2| connected through suitable reducing gearing to an output shaft 22. On shaft 22 is a pulley 23 connected by a belt 24 to the pulley 28; Fixed to shaft l1 and above the table top I3 is a pulley 26 for the purpose hereinafter appearing.

Rotatably mounted on stand H is a. rotary plate 28 disposed at a level above pulley Attached to the underside of plate 28 are casters 29 supporting wheels 38 contacting the upper surface of the topwall I3. Plate 28 is formed with an openin through which the shaft passes, and is provided with a bushing" 3| in which the shaft I! is journalled. At the upper end of shaft. IT is a circular plate 32.ofsmaller diameter than the plate 28. Shaft [1 passes through the center opening in plate 22. Attached to the upper end of shaft I1 is cap 33. Mounted for rotation on plates 28, 32 are a plurality ofturrets. '1 4such turrets being shown for the purpose of illustration. Each tu'rret comprises a vertical shaft 34 passing through openings. in saidplates. Fixed to the lower end of each shaft 34 is a pulley 35 aligned withpu1- ley 26. Fixed to each shaft 34 and disposedbelow plate 32 is agear 36. On. each. shaft 34 andv disposed above plate 28 is a bushing 37. Mounted. on each bushing 3'! isv a rotary plate 38. having an. opening through which shaft 34 passes. Also mounted for rotation on each shaft 34, is a plate 40 disposed above the gear 36, for the purpose: hereinafter appearing.

The plates 46 and 38' are circular. 'Plate. 40 is formed with equiangularly spaced radial notches 4| at the periphery thereof. Plate 38 is-furthermoreformed at. the periphery thereof with equiangularly spaced cut outs 42 aligned with the notches 4|. lel edges 43 extending to the peripheral edge 44. of plate 38, and a straight edge 45intercon-- necting the inner ends of edges 43.

aligned with edge 45 of the cutout; It is also formed with a pair of upstanding parallel projections 48,. the inner sides of which are flush with the edges 43. The projections 48 are formed with aligned U-shaped notches 49- opening upwardly for the purpose hereinafter appearing.

Mounted for tilting on each bracket 46' is a plate 58 formed with a pair of pintles 5| received in the notches 4-9. The pintles 5| are in alignment and are in a line offset from the axis of plate. 56. Plate 56 is formed with a pair of diametrically disposed notched lugs 53. A line interconnecting the lugs 53 is parallel to a line interconnecting the pintles 5|.

It will be noted that plate 56rests onbracket 46, but may beswivelled about the pintles 5|. The notch or cut out 42 permits the plate 58 to betilted-ina counterclockwise direction, looking. at Fig. 6 of.the'drawing,-,. tobring said plate from theposition shown in Fig. 6 to the position shown in Fig. '7. Plate 5ll=may be formed with an; annular upstanding. flange 52, for the pur- Each cut out-42 has paral for the can 53 is removed prior to putting the can on the machine. Replacing the cover is a closure disc 54 provided with a pouring valve 55, more fully disclosed in my abandoned ap plication, Serial No. 789,222, filed December 2, 1947. The closure member 54 is formed with a through opening, through which extends a shaft 56. Attached to the shaft and within the can is a stirring blade 51. On the closure disc 54 are a pair of. diametrical lugs 58 interconnected to lugs 53 by a pair of connecting rods 59. Fixed to the upper end of the shaft 56 is a pinion 51a in engagement with gear 36. By lifting the catch 6|, the upper end of shaft 56 is released and the can 53 may be tilted about the pintles 5| so'that paint may be poured from the spout 62.

Between each pair of adjacent turrets there is rotatably mounted a vertical shaft 10. Shaft 10. passes through suitable openings in plates 28 and 32. Above plate 28 is a bushing 1| through which. each shaft 10 passes. Attached to the lower end of each shaft 10 is a pulley 12, in alignment with the pulleys 35 and 26. Mounted on bushing H is a bracket 15, through which the shaft 1|) passes. Mounted on bracket 15 is a plate 46 similar to the plate 46, described hereinabove. Swivelled in the notches 49 of the lugs 48- of said plate 46 is a can 53 mounted on a plate and closed by the closure disc 54 and provided with a central shaft 56 passing through the closure disc and carrying the pinion 51a.

Attached to plate 32 is a topbracket 11 extending beyond the'periphery of said plate. The shaft 10 passes throughbracket TI and the top plate 32. Fixed to the shaft 10 is a pinion adapted to mesh with the last mentioned pinion 51a; Bracket TI is formed with a notch 8| to receive the upper end of shaft 56. Fixed to the top of bracket TI is a spring 83 similar to spring (ill-and having a catch 84 at its outer end adapted to releasably engage the upper end of said shaft-56 when the. spring catch is released. The can may be tilted aboutits pintles 5|.

It will now be understood that the shafts 10 are spaced apart degrees from each other and are spaced apart 45 degrees from the. shafts 34. The plate 28 may be rotated to bring any one of the cans between the turrets to aninitialposition relative to the base or stand so that paint may be poured therefrom.

Means is provided to retain each turret against rotation with each of the cans thereon in pouring position. To this end there is mounted on plate 28 and adjacent each turret- T, a pivot bracket 90. Pivoted thereto is one end of a lever 94. Gneach lever 9| is an upstanding pin 92. Interposed between the lever 9| and plate 28 is a'coil compression spring 93- Plate 28 and lever 9| may be provided with guide lugs projecting into opposite ends of the spring. Each turret plate 36 is formed with a hole or opening 95 adjacent each can and adapted to receive pin 92. When the lever 9| is depressed, pin 92 moves below opening 95 to permit rotation of turret plate 33. The lever 9| for each turret and the openings 95 for the turret are so positioned that plate 38 may be stopped in one of four positions and in each position one can will be in pouring position where it may be tilted.

Rotatably mounted on the underside of plate 28 is an idler pulley 91. Disposed about the pulleys 91, 35 and 26, is a belt 98. When the j motor 2.! is running, belt 24 pushes pulley 26 which, due to the connection of the belt 98, rotates shafts 34 and 10 simultaneously in opposite directions, that is, all the shafts 34 rotate in one directionand all the shafts H3 rotate in an opposite directon. Plate 28 may be rotated by hand to bring any desired turret to a base position relative to the stand. Furthermore, each turret may be rotated. by hand to bring any desired can to a position relative to the stand. The motor serves to cause rotation of the stirrers for all the paint cans simultaneous- 1y.

While mention is made of paint cans, it is understood that any suitable receptacle containing any liquid or material to be stirred is meant where the term paint can is used. 1 It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is Well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
