Abstract

750,892. Screwing-up and unscrewing nuts &c. LEDLOY, Ltd. Sept. 24, 1953 [July 4, 1952], No. 16807/52. Class 83 (3). [Also in Group XXIII] A torque-multiplying wrench, which may be power - operated, for tightening a screwed fastener assembly, has a part adapted for connection with a non-rotative member of a fastener assembly so as to be fixed against rotation during the tightening operation, the said wrench part acting as the reaction member of a torquemultiplying system whereby the torque reaction is transmitted to the non-rotative member. A wrench, for tightening a nut on a bolt such as that described in Specification 750,894, [Group XXV], comprises two relatively rotatable members, viz. a socket 12 at one end of a central shaft 10 and engageable with the bolt-extension 13, and a box-spanner 34 rotatable on the shaft 10 for engagement with the nut 35. The part 34 has an integral ratchet-wheel 33 engaged by spring-pressed pawls in a ring 28. The ring 28 is connected by bolts 27 to a driving-plate 25 rotatable on the spindle 10. A spindle 19 having a square-end 20 for engagement by an operating lever is mounted in a bearing plate 15 keyed at 16 to the shaft 10. The bearing plate is the reaction member of the wrench. The lower end of the spindle has an eccentric stub 22 upon which is a shoe 23 slidable in a slot in the driving plate 25. The spindle is turned in its seating in the plate 15 by angular movement of the lever to produce angular movement of the driving plate 25. In a modification the spindle and eccentric stub are duplicated. The socket 12 may incorporate a clutch or other means for gripping the end of the bolt. In another modification, the torque-multiplying means comprises reduction gearing. In another modification the wrench is operated as by electrical means or by utilizing applied energy or impact. The wrench may incorporate a torque-measuring device or a torque .overload-release such as a slipping clutch.
