Abstract: 237,712. Johnson, J. Y., (Smith, Drum, & Co.). July 8, 1924. Agitating materials and liquids together; cages for materials, lifting and discharging.-In dyeing &c. machines comprising a vat body 1 having a perforated cage 4 which carries a paddlewheel 10, the cage and paddle wheel being movable as one structure into and out of the vat, the cage shifting mechanism and the paddle-wheel actuating mechanism are both driven from the same motor. A single control element is provided adapted simultaneously to disconnect the paddle wheel from and operatively connect the cage with the motor and vice-versa. The cage 4 is journaled on a shaft 5 and carries, in bearings 8, 8, a shaft 9 which carries a paddle-wheel 10 and has at one end a toothed wheel 11 engaging a toothed wheel 12 on a spindle 13. The spindle 13 carries a sprocket wheel 14 connected by a chain 15 with a sprocket wheel 16 loosely mounted on a shaft 17 journaled at 18, 19 in bearings carried on the body 1. The shaft 17 carries at its inner end a bevel toothed wheel 21 which engages a bevel toothed wheel 22 secured to a toothed wheel 23 loosely mounted on a shaft 24. The shaft 24 carries a worm 25 engaging with a worm-wheel 26 on a shaft 27 journaled in the body 1 and carrying at each end an arm 28 each of which is connected by a rod 29 to an arm 30 secured at 30<a> to the cage 4. Each arm 30 has secured to it an arm 31 piovted on the shaft 5, a third arm 32, also pivoted on the shaft 5, being secured to that end of the arm 30 which is secured to the cage. The means for actuating the shaft 27 and thereby elevating and lowering the cage 4 and also for driving the paddle-wheel 10 comprises an electric motor 34, the shaft of which carries a pinion 35 engaging a toothed wheel 36 on a countershaft 37 which carries a pinion 39 engaging with the toothed wheel 23. The toothed wheel 23, which is loosely mounted on the shaft 24, carries a clutch element 41 adapted to be engaged by a movable clutch element 42 on the shaft 24, the element 42 being moved into and out of engagement with the element 41 bv the rocking of a shaft 43 which carries arms 44 having pins 45 engaging a circumferential groove 46 in the element 42, the shaft 43 carrying an arm 47 connected by a rod 48 with a pivoted operating lever 49. The arm 47 is also connected by a rod 52 with an arm 53 on a shaft 54 carrying at its upper end a forked arm 56 carrying pins 57 engaging a circumferential groove 58 in a movable clutch element 59 splined to the shaft 17. The sprocket wheel 16, which, as stated, is loosely mounted on the shaft 17, carries a clutch element 61 adapted to be engaged by the element 59 upon operation of the lever 49 which thus controls both clutches, the arrangement being such that when the clutch 41, 42 is engaged, the clutch 59, 61 is out of engagement and vice versa. The. motor 34 is controlled by a switch which is operatively connected by lever mechanism with the shaft 5 in such a manner that, with the clutch 41, 42 engaged so as to enable the motor to elevate the cage 4, the switch is moved to its open position on the cage 4 attaining the discharging position shown in Fig. 4. After discharge of the goods, the switch is moved by a hand-operated lever so as to reverse the motor and thus lower the cage 4, which, when it has nearly assumed its final position, moves the switch once more into the open position. The lever 49 is then operated fo disengage the clutch 41, 42 and engage the clutch 59, 61 and the handoperated lever of the switch is moved back to its initial position to restart the motor to actuate the paddle-wheel 10.
