Abstract: 527,482. Wringers. BRITISH THOMSONHOUSTON CO., Ltd. April 13, 1939, No. 11223. Convention date, April 13, 1938. [Class 138 (ii)] Relates to a wringer wherein the drive is connected and the pressure simultaneously applied by the swinging of a control member 82, Figs. 4 and 9, in either direction from a neutral vertical position to an inclined position wherein it substantially encloses the feeding side of the upper roller 71. This roller is journalled on a shaft 80 fixed between depending arms 81, 81a of the control bar 82, and rollers 97 carried by the arms engage cam surfaces formed on slots 86 in plates 87 which are slidably mounted in the side stiles 1, 2. Two leaf springs 90 are arranged beneath the lower cross bar 3 of the wringer frame, the ends of the upper spring bearing on the lower face of the cross bar at points adjacent the side stiles. The centre of this spring bears on the centre of the other spring which is oppositely arranged and of which the ends bear on the lower ends of slots 89 in the plates 87. Other slots 92 in the plates 87 provide clearance for the shaft of the lower roller. A projection 101 on an arm 100 projecting from the lower end of arm 81 engages a vertical slot 102 in a member 51 slidably mounted in a horizontal slot 52, Fig. 5, in the stile 1. A lever 48 is pivoted at 49, on a bracket 50 formed on the member 51, the under face of the lever being grooved to receive a pin 46, Fig. 4, projecting upwardly from a bar 40 slidably mounted about a fixed pin 43 and provided with a downwardly projecting tongue 38 which operates a clutch member 35. When the control member 82 is in the central neutral position, a spring 54 moves the various levers and bars to the position shown wherein the clutch is neutral. Operation of the control member in either direction moves the clutch in corresponding direction to couple the shaft 28 to one or other of the constantly rotating levers 37. The arrangement provides for the clutch member to be yieldingly moved to the engaged position, so that the teeth 36 and those on the bevels do not jam, and to be positively moved from the engaged to the neutral position. The pressure is simultaneously applied, or released, by the engagement of the rollers 97 with the cams of the slots 86. The upper ends of the slots may be partially closed by hook shaped members 88 to prevent the control bar and the upper roller riding up out of the slots on release of the pressure but permitting the removal of these members by hand. The portions of the upper ends of the slots not closed by the hooks 88 may be closed by pivoted plates 88a, Fig. 6. The hook shaped portions may be replaced by bosses formed in the stiles. To prevent the control bar being moved unintentionally from neutral position a projection 103, Fig. 9, on the arm 81a engages a groove 104 in a spring strip 105. A drainboard 70 is tilted according to the direction of rotation of the rollers by means of a tab 111 on a plate 110 rotatable about the lower roller shaft, the plate being provided with a pin 109 engaging a channel in an upwardly extending ear 108 formed on the drainboard. The tab lies adjacent the nip of the rollers and on the direction of rotation being reversed, is drawn into the nip and swings the drainboard to its other position.
