Abstract

650,327. Winches. RUSTON-BUCYRUS, Ltd. Jan. 28, 1948, No. 2551. Convention date, Feb. 5, 1947. [Class 78 (v)] [Also in Group XXI] A winch for a drag-line excavator which can be converted into a winch suitable for a power shovel comprises a driven rotating shaft 45<1> on which are mounted freely-revolving sleeves 85, 86 separated by a freely-rotatable spider 46<11> in which is journalled planet gears 61<1> meshing with bevel gears 52<1>, 53<1> formed on the sleeves 85, 86. Each sleeve may be driven from the shaft 45<1> through clutch units 51<1>, 541 and may each be separately controlled by brake units 501, 581. On the sleeves 85, 86 are concentrically-mounted split drums 82, 83. To convert the winch to one suitable to operate a power shovel, the drums 82, 83 are disconnected from the sleeves 85, 86 and bolted to the spider 46<11> which is provided with a brake 78<1>. A driving'sprocket 371 is secured to the sleeve 86. In a modified construction, the brake 78<1> is omitted and when converting the winch from one suitable for a drag-line excavator to one suitable for a power shovel, the two split drums are replaced by a single drum in meshing contact with the spider. Specification 593,673 is referred to. The Specification as open to inspection under Sect. 91 comprises also a further winch of modified construction but operating similarly to the above. This subject-matter does not appear in the Specification as accepted.
