Abstract The present invention is directed to improvements in the coupling mechanism for connecting a rotatably mounted drum to a carrier used to convey a material to be processed in the drum to and from the drum. The coupling mechanism is adapted to connect the input opening of the drum and the discharge end of the carrier in a sealed relationship while simultaneously elevating the carrier so that it may be rotated with the drum. The coupling includes a pair of oppositely disposed slides which are mounted to reciprocate vertically to elevate the carrier and each of these slides is formed with a central passageway which is axially aligned with the axis of rotation when the carrier is in the elevated position. The clamping mechanism which serves to clamp the carrier to the drum is provided with a roller which rotates within the axially aligned passageway of the reciprocally mounted slides when the assembly is rotatably driven.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
93 words
In a mixing apparatus having a first vessel mounted for rotation about an axis and a second vessel mountable on said first vessel for rotation with said first vessel about said axis, the improvement of guide means having a guide surface extending circumferentially about said axis and follower means extending between said second vessel and said guide surface, said follower means engaging said guide surface and securing said first and second vessels in sealed relationship with one another at all rotational positions of said first and second vessels with respect to said axis.
Claim 2
Dependent Claim
93 words
In a mixing apparatus having a first vessel mounted for rotation about an axis and a second vessel mountable on said first vessel for rotation with said first vessel about said axis, the improvement of guide means having a guide surface extending circumferentially about said axis and follower means extending between said second vessel and said guide surface, said follower means engaging said guide surface and securing said first and second vessels in sealed relationship with one another at all rotational positions of said first and second vessels with respect to said axis.
Claim 3
Dependent Claim
78 words
A mixing apparatus as claimed in claim 1 wherein said guide means is mounted for movement between a first position in which the guide surface extends circumferentially as aforesaid and a second position in which the centre of gravitation of said guide surface is offset with respect to said axis and means for moving said guide means to and from said first and second positions to move said vessels into and out of sealed relationship with one another.
Claim 4
Dependent Claim
38 words
A mixing apparatus as claimed in claim 2 wherein said second position is lower than said first position and said means for moving said guide means serves to elevate said second vessel into engagement with said first vessel.
Claim 5
Dependent Claim
86 words
A mixing apparatus as claimed in claim 3 wherein said guide means includes a plate member having a circular opening therein, the peripheral edge of said circular opening forming said guide surface, and slide means for mounting said plate for movement between said elevated and lowered position of said guide surface, said follower means including means for engaging said second vessel and elevating it into sealing engagement with said first vessel in response to movement of said guide plate from said lowered to said elevated position.
Claim 6
Dependent Claim
30 words
A mixing apparatus as claimed in claim 1 wherein said follower means incudes clamping means for clamping said second vessel in said sealed relationship with respect to said first vessel.
