Abstract

334,730. Dassonville, M. March 9, 1929, [Convention date]. Dipping-apparatus. - A machine for washing. dyeing, &c. in which a set of tanks are arranged circularly around a central vertical axis, the material to be treated being suspended from a frame carried on the vertical axis and which can be rotated thereon and given a vertical ascending and descending motion to immerse the material successively in the tanks, has means provided for giving the frame a vertical reciprocating motion of small amplitude for shaking the material in the tanks without removing it therefrom. The suspending frame is carried by a tubular shaft 12 resting on a collar and ball race 16 attached to two connecting rods 17, 18. These rods are connected to two beams 19, 20 pivoted on a shaft 21 and moved respectively by frames 26, 35, also pivoted to shaft 21, the cross-bars of which 24, 34 may engage in hooks 25, 33. The weight of the suspending frame is greater than the counterweight 22, 23 so that it always tends to move downwardly. To raise the suspending frame a rack and pinion 27, 32 is driven, preferably by an independent prime mover, the bar 24 engaging the hook 25 and forcing it downwardly. In order that the shaking motion may be imparted to the material in the tanks, the rack 27 is raised so that the bar 24 leaves the hook 25 and motion is then imparted to the frame 35 and beam 20 by an independently-driven crank and connecting rod 37, 36, the frame 26, rack and pinion 27, 32 remaining stationary. The rotary motion of the suspending frame is obtained by a separate prime mover through shafts. bevels, &c. A space is preferably provided between a pair of the tanks to allow for loading and unloading the material.
