Title: Improvements in safety mechanisms for wringers and the like
IPC: D06F45/18
Filed: 1939-05-09
Abstract: 533,498. Wringers. LOVELL MANUFACTURING CO. May 9, 1939, No. 13870. Convention date, May 31, 1938. [Class 138 (ii)] [Also in Group XXIV] A wringer is provided with releasable pressure applying means, releasable driving means, safety mechanism for releasing one or both of said means, and mechanism to prevent operation of the pressure release means during setting of the wringer in operative position. The wringer is supported by a casing 27 mounted to swivel on a gear box secured at the top of a supporting pillar 26 and housing the gearing 37, 38 for driving the lower roller 4 from the driven shaft 35 extending down the pillar. The top plate 14 carrying the pressure-applying spring 11 is secured by a hinge 16 at one end and at the other end by toggle mechanism comprising a U- shaped lever 17 connected by links 21 to the stile 3 and pivotally engaging the top plate by a hook 20a. The gear box carries a pivot 47 for mounting a toothed segment 46a engaging a pinion 45 for actuating a crank pin 43 to move a clutch 40 from neutral position into engagement with either driving wheel 38 when the wringer is moved to set position, Figs. 4 and 6, swing to the tail 48 of the segment engaging a grooved plate 31 fixed to the stile 2. Springs 50 on the segment tend to centralize the wringer in neutral position. A spring-pressed rod 58 bears against a surface 53 on the gear box which is formed with recesses 54, 55, Fig. 6, the other end of the rod bearing against the lever 17. With the wringer in set position for operation the rod 58 is in one or other of the recesses 55, and bodily displacement of the wringer about its pivotal mounting, as by pulling or pushing in case the operator's fingers are caught, causes the rod to be pushed back thus pressing back the lever 17 and breaking the toggle so that the pressure is released This or further movement of the wringer also operates through the segment 46a to disengage the clutch and thus arrest the drive. The pressure can now be reset, and to provide against releasing the pressure on swinging the wringer to set or operative position, a U- shaped member 64 is pivoted on the lever 17 and bent round at the bottom to form an upturned lip. By pressing this member inwards against the spring 66 the lip rocks a device 62 pivoted in the stile 3 so as to raise the rod 58 which can then pass through an aperture in the lever 17 until setting has been effected and pressure on the member 64 removed.

[Class 82 (ii).] In bronzing iron, steel, or their alloys the metal is treated to remove grease, subjected to one or two pickling treatments, immersed in an alkaline solution containing lead dioxide, a nitrated derivative of toluene or phenol, and nitric acid, with or without ammonia, and finally immersed in hot vegetable oil to remove traces of alkali. The metals are preferably degreased in a bath of boiling 10-20 per cent caustic soda and then washed. They are then pickled in a bath of 5-10 per cent sulphuric, hydrochloric, or hydrofluoric acid. Articles made of iron or ordinary carbon steels are then washed and transferred to the bronzing bath, but articles of cast iron or of alloy steels are subjected to a second pickling in a bath of 10 per cent hydrofluoric acid contained in a basin of paraffined wood. The bronzing bath may comprise 60 parts of caustic soda, caustic potash or ammoniacal caustic soda, 2 parts of trinitrotoluene or trinitrophenol, 0-8 part of lead dioxide, and 2À95 parts of nitric acid. For immersion in the bronzing bath the articles are placed in small boxes of thin sheet iron, with double walls and double ends, thermally and electrically insulated, and with perforated covers. Ordinary iron, cast iron, carbon steels, and alloy steels including rustless steels may be oxidized by the process.
