A vibratory mixer for mixing ingredients by shaking comprising a load platform (51) for receiving a container (88) which holds the ingredients to be mixed, clamping means (47) cooperable with the load platform to clamp a container (88) therebetween, means (14, 26 to 48) for effecting relative movement between the load platform (51) and the clamping means (47) so as to clamp and unclamp a container, said means comprising at least one lead screw (38, 42) and a first motor (14) operable to drive the or each screw, the or at least one of the lead screws (42) being axially movable, the apparatus further comprising a second motor (13) operable to shake the load platform (51), and control means operable to control the sequence of operation of the apparatus and comprising switch means (65) connected in circuit with the first motor (14) and actuatable on axial movement of said the or at least one lead screw (42) which takes place due to the reaction of a container (88) being clamped between the load platform (51) and the clamping means (47) whereby the first motor (14) is de-energised before the second motor (13) is energised. |
