Filed: 1946-06-22
Abstract: 617,106. Wringing-machines. GOLD, R. L. June 22,1946, No. 18794. [Class 138(ii)] In a twin-roller wringing-machine in which the upper roller 5 is pressed on the lower roller 15 by a plate spring 26 mounted in a carrier 24 arranged parallel to the rollers, the stress of the spring is initially absorbed by the end portions of the carrier and by a centre abutment 25 therein and is transferred through the ends of the spring to the bearings 18 of the upper roller by a small movement of the carrier. The rollers 5, 15 are engaged by bearings 18, 19 contained in the end members 10 of a frame formed of four channel-section members 10, 11, 12. Extension pieces 20, 21 on the bearings 18. 19 are disposed between the ends of the rollers, and are pressed apart by springs 22 which serve partially to balance the upper roller 5 and operating mechanism. The plate spring 26 is mounted in the carrier 24 which is of channel section and disposed within the upper frame member 12. When the spring is inserted in the carrier 24, it is stressed to a predetermined degree by causing its a pin constituting the abutment 25 and its ends to bear on the carrier. The ends of the spring project from the carrier and rest on the upper bearings 18 so that downward movement of the carrier transfers the spring pressure to the top roller 5. Movement of the carrier 24 is controlled by a handle 35 locked to a screw-threaded hollow sleeve 29 which is connected by a quick-release mechanism to the carrier 24. The sleeve 29 screws into a nut carried by a bracket 14 fixed to the frame-member 12. The quick-release mechanism comprises a rod 28, which is connected at one end to the carrier 24 and is capable of sliding in the sleeve 29, and a spring-pressed pawl 30 pivotally mounted on the rod 28. An abutment on the pawl 30 normally engages the lower edge of the sleeve 29, enabling pressure to be transmitted to the plate spring 26; the pressure is released when the pawl 30 is pressed inwardly by a cranked rod 42 so as to disengage the abutment. The cranked rod 42 is pivotally mounted on the frame in brackets 45 and has downward extensions 43 connected by an operating bar 46 extending along the front of the machine. Pressure is released on slight upward movement of this bar 46. The wringer is enclosed in a two-piece cover 4 bolted to brackets on the frame, the bolts for the front portion being arranged internally. One portion of the cover may have projecting clips 51 to position the other, and a moulded rubber strip may be provided at the joint between the two portions. The front portion of the cover is shaped to provide an incline 6, Fig. 2, so as to provide a feeding surface towards the rollers. The drive is applied to the lower roller from a gear-box 57 containing a spring-pressed clutch 56, adapted to be released by a cam-lever 58. The gearbox contains an additional bevel gear 63 adapted to drive an ironing .machine. The wringer may be mounted on the top of a wash-boiler with its feed-in side disposed adjacent the vessel of the boiler.
