Abstract
Abstract A device for mixing cans of different sizes for paints, said device comprising a pedestal and a frame rotatably mounted on said frame around a first axis. The frame is supporting a disc for a can to be mixed rotatably around a second axis perpendicular to said first axis. The device is provided with driving means for rotating said frame and said disc around said axis. A transmission means is coupled to rotate said disc selectively with at least two different speeds, a lower speed for a larger can and a higher speed for a smaller can.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
226 words
An improved device for mixing cans of different sizes for paints, in particular paints and toners, which device comprises a pedestal, a frame mounted on said pedestal to rotate around a first axis, a first rotary drive element fastened to said frame to bring about rotation thereof, a disc supported by said frame for fastening a can of paint to said frame, said disc being mounted to rotate around a second axis extending transversely with respect to said first axis, a second rotary drive element fastened to said pedestal coaxially with said first rotary drive element, power means connected to said first rotary drive element to bring about rotation thereof, and driving means connecting said second rotary drive element to said disc to bring about rotation of saiD disc upon rotation of said first rotary drive element, the improvement consisting in that said disc is axially displaceably supported by said frame, and in that transmission means are coupled between said disc and said driving means, said transmission means being effective to change the number of revolutions of said disc around said second axis when said disc is displaced axially, so that when said disc is at a position corresponding to the largest paint can size, the number of revolutions is lower than when said disc is in a position corresponding to a smaller paint can size.
Claim 2
Dependent Claim
226 words
An improved device for mixing cans of different sizes for paints, in particular paints and toners, which device comprises a pedestal, a frame mounted on said pedestal to rotate around a first axis, a first rotary drive element fastened to said frame to bring about rotation thereof, a disc supported by said frame for fastening a can of paint to said frame, said disc being mounted to rotate around a second axis extending transversely with respect to said first axis, a second rotary drive element fastened to said pedestal coaxially with said first rotary drive element, power means connected to said first rotary drive element to bring about rotation thereof, and driving means connecting said second rotary drive element to said disc to bring about rotation of saiD disc upon rotation of said first rotary drive element, the improvement consisting in that said disc is axially displaceably supported by said frame, and in that transmission means are coupled between said disc and said driving means, said transmission means being effective to change the number of revolutions of said disc around said second axis when said disc is displaced axially, so that when said disc is at a position corresponding to the largest paint can size, the number of revolutions is lower than when said disc is in a position corresponding to a smaller paint can size.
Claim 3
Dependent Claim
68 words
A mixing device according to claim 1, wherein the transmission means comprise a plurality of coaxial rotary drive elements of different respective sizes rotatably mounted to a rotable support, each rotary drive element of said plurality being coupled to said driving means and being selectively coupled in driving engagement with said disc while each other rotary drive element of said plurality is disconnected from engagement with said disc.
Claim 4
Dependent Claim
46 words
A mixing device according to claim 2, wherein said driving means comprise a belt and said second rotary drive element and said plurality of rotary drive elements comprise respective pulleys, the belt being trained around said pulleys and around an idler pulley mounted to said frame.
Claim 5
Dependent Claim
25 words
A mixing device as claimed in claim 2, comprising peg and hole means coupling said disc to one of said plurality of rotary drive elements.
Claim 6
Dependent Claim
128 words
A mixing device according to claim 2, wherein said disc is provided with a tubular shaft and a locking lever provided with a spring is pivotably mounted inside said shaft, said lever pivoting to a coupling position when the shaft is axially displaced to a first position, thus locking one rotary drive element of said plurality in engagement with said shaft, while engagement between each other rotary drive element of said plurality and said disc is disconnected, and pivoting to a releasing position when the shaft is axially displaced to a second position, thus disconnecting said one rotary drive element from engagement with said shaft, while engagement between another rotary drive element of said plurality and said disc is established owing to the axial displacement of said shaft.
