Abstract: 466,230. Wringers. SCHROEDER, S. E. Feb. 28, 1936, No. 6039. [Class 138 (ii)] Relates to a wringer wherein the release of the pressure between the rollers disconnects the drive to the rollers. The upper roller 58, Fig. 2, is carried wholly in a frame B pivoted about trunnions 80 at the top of arms 43 extending upwardly from the stationary frame A. The lower ends 99 of spring-pressed latching arms 95 slidably mounted in the side members of the swinging frame normally engage in gaps between guide members 98 formed within the stationary frame thereby holding the swinging frame vertically over the stationary frame. The tops of the latching arms are engaged by the ends of a bar 108 slidably mounted in the top of the swinging frame so that the latching arms are normally locked in depressed position and the swinging frame locked to the stationary frame. The locking bar 108 can be moved to the right so that recesses therein register with the' tops of the latching arms whereby the latter rise and the swinging frame becomes unlocked from the stationary frame and swings about its pivots 80 due to the reaction between the intermeshing gear wheels 62. The movement of the locking bar to the right may be effected in three ways One way is by the manual rotation of a saddle 119, pivotally mounted on the swinging frame in either - direction and from either side of the wringer. The saddle carries a transverse cam plate 120 which engages a depending U-shaped frame 114 on the bar 108. Movement of the locking bar is also effected by the wrapping of an article around the upper roller, the article then engaging a depending longitudinal finger 131 on the cam plate 120 to actuate the latter in the manner in which it is actuated by the saddle 119. The third method of operating the locking bar is by the manual depression of one of a pair of push-buttons, one button being positioned on each side of the stationary frame and actuating, through a linkage, a cam plate which bears against the end of the locking bar. Wringing pressure is adjusted by the rotation of a knob 94 which causes sleeves 91 to compress springs 90 against followers 87, the knob being mounted on the shaft on which the followers are freely mounted and to which the adjusters are splined, the latter working in opposite directions in fixed sleeves 54. The followers are linked to levers 82 pivoted to the swinging frame at 83 and linked to the bearing blocks of the upper roller shaft. The lower roller 59 is raised into pressure engagement with the upper roller and the pressure is applied and released by rotation of a camshaft 70 as described in Specification 465,424. The swing- ing frame is provided with cam surfaces 201, Fig. 11a, engaging the end of a rod 200 which projects into the gear case C, Fig. 17. The latter is provided with forward and reverse bevels 166, 167 splined to a vertical drive shaft 163 and movable by a handle 157 from a neutral position so that one or other engages a gear-wheel 160 coupled to the lower roller shaft 60 through a sleeve 162. A sliding latching plate 183, Fig. 18, is held by a catch 189 to hold the bevel wheels in engagement with the gear wheel 60, but when the rod 200 is pushed into engagement with the catch 189 due to the release of the swinging frame from the stationary frame and the action of the cam surfaces 201, the plate 183 becomes unlatched and is moved by springs 190 to move the bevel wheels to neutral position. Manual movement of the bevels is effected by a handle 157, Fig. 23, having a pinion 178 which engages the teeth 168 of the sleeve 165 to which the bevels are secured. The drip tray 202, Fig. 2, is also tilted in the appropriate direction according to the direction of rotation of the wringer rollers, by the movement of the handle 157, the pinion 178 also engaging a quadrant 155, Fig. 23, on a rotatable sleeve having axial projections which engage sliding plates connected to the drip tray
