Abstract
Abstract A mixer having an open top mixing box accommodating a pair of lower augers and a pair of upper paddle conveyors drivably connected to the augers. A power box pivotally mounted on one end of the mixing box is drivably connected to the augers with releasable drive connections. The power box is a motor driven power transmission assembly that can be disconnected from the augers and removed from the mixing box. A movable door associated with the bottom of the mixing box is used to selectively open and close a discharge opening allowing mixed and blended material to be discharged into a conveyor.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
173 words
An apparatus for driving a movable means, said movable means including driven shaft means comprising: power means having drive shaft means for driving the drive shaft means, releasable means drivably connecting the drive shaft of the power means with the driven shaft means whereby the power means rotates the driven shaft means, said releasable means includes first means having at least one first arm secured to the shaft means, and second means having at least one second arm secured to and moved by the drive shaft means to the power means, one of said shaft means having an axial passage having an open end, and the other of said shaft means having projection means adapted to fit into the axial passage through the open end thereof to support said one of said shaft means on the other of said shaft means, said first and second arms being engageable with each other to transmit power from the power means to the driven shaft means when the projection means is located in said axial passage.
Claim 2
Independent Claim
173 words
An apparatus for driving a movable means, said movable means including driven shaft means comprising: power means having drive shaft means for driving the drive shaft means, releasable means drivably connecting the drive shaft of the power means with the driven shaft means whereby the power means rotates the driven shaft means, said releasable means includes first means having at least one first arm secured to the shaft means, and second means having at least one second arm secured to and moved by the drive shaft means to the power means, one of said shaft means having an axial passage having an open end, and the other of said shaft means having projection means adapted to fit into the axial passage through the open end thereof to support said one of said shaft means on the other of said shaft means, said first and second arms being engageable with each other to transmit power from the power means to the driven shaft means when the projection means is located in said axial passage.
Claim 3
Dependent Claim
50 words
The apparatus of claim 1 wherein: said first means has a plurality of arcuately spaced first arms, and said second means has a plurality of arcuately spaced second arms, adjacent first and second arms being engageable with each other to transmit power from the power means to the movable means.
Claim 4
Dependent Claim
58 words
The apparatus of claim 1 wherein: the first arm and second arm each have side edges and project in radial outward directions, said first and second arms being inclined outwardly in opposite directions so that the first arm extends adjacent the second arm and the adjacent side edges of the adjacent first and second arms engage each other.
Claim 5
Dependent Claim
46 words
The apparatus of claim 1 including: support means, means mounting the power means on the support means, said means mounting the power means on the support means including pivot means allowing the power means to swing away from said movable means to release the releasable means.
Claim 6
Dependent Claim
71 words
The apparatus of claim 4 wherein: the power means has a housing having a chamber, power input shaft means rotatably mounted on the housing, power output shaft means rotatably mounted on the housing, and power transmission means located in said chamber drivably connecting the input shaft means to the output shaft means, and motor means for driving the input shaft means, said releasable means being connected to the output shaft means.
Claim 7
Independent Claim
178 words
An apparatus for driving a plurality of rotatable means comprising: power means having a plurality of drive shaft means for rotating the rotatable means, a plurality of releasable drive means connecting the drive shaft means of the power means with the rotatable means whereby the power means rotates the rotatable means, each releasable drive means comprising first means having at least one first arm secured to a rotatable means, and second means having at least one second arm secured to and moved by a drive shaft means of the power means, one of said first and second means having projection means and the other of said first and second means having an axial passage with an open end to accommodate the projection means to support said one of the first and second means on the other of said first and second means, said first and second arms being engageable with each other to transmit power from the power means to the rotatable means to rotate said rotatable means when the projection means is located in said axial passage.
Claim 8
Independent Claim
178 words
An apparatus for driving a plurality of rotatable means comprising: power means having a plurality of drive shaft means for rotating the rotatable means, a plurality of releasable drive means connecting the drive shaft means of the power means with the rotatable means whereby the power means rotates the rotatable means, each releasable drive means comprising first means having at least one first arm secured to a rotatable means, and second means having at least one second arm secured to and moved by a drive shaft means of the power means, one of said first and second means having projection means and the other of said first and second means having an axial passage with an open end to accommodate the projection means to support said one of the first and second means on the other of said first and second means, said first and second arms being engageable with each other to transmit power from the power means to the rotatable means to rotate said rotatable means when the projection means is located in said axial passage.
Claim 9
Dependent Claim
50 words
The apparatus of claim 6 wherein: said first means has a plurality of arcuately spaced first arms, and said second means has a plurality of arcuately spaced second arms, adjacent first and second arms being engageable with each other to transmit power from the power means to the movable means.
Claim 10
Dependent Claim
58 words
The apparatus of claim 7 wherein: the first arms and second arms each have side edges and project in radial outward directions, said first and second arms being inclined outwardly in opposite directions so that the first arms extend between the second arms and the adjacent side edges of the adjacent first and second arms engage each other.
Claim 11
Dependent Claim
47 words
The apparatus of claim 6 wherein: each of said rotatable means has an axial passage and each of said drive shaft means has projection means adapted to fit into an axial passage through the open end thereof to support the rotatable means on said drive shaft means.
Claim 12
Dependent Claim
37 words
The apparatus of claim 6 wherein: said plurality of rotatable means comprises a pair of driven shaft means and said drive shaft means comprises a pair of drive shaft means axially aligned with the driven shaft means.
Claim 13
Dependent Claim
53 words
The apparatus of claim 10 wherein: each of said driven shaft means has an axial passage and each of said drive shaft means has projection means adapted to be located in a passage through the open end thereof when the first arms and second arms are located in driving relation with each other.
