904,903. Wire &c. compensators. GOLDE, H. Jan. 6, 1959 [Jan. 9, 1958], No. 557/59. Class 105. [Also in Group XXXI] A device for causing two longitudinallyextending members such as cables 1, 4 to move lengthwise in opposite directions comprises a housing 7, 8 (Fig. 4) or 20 (Fig. 6) for driving gear-wheel means 10 or 21, 22 drivable by a shaft 11 or 23, the cables 1, 4 being so guided in cable sheaths 3, 6 that screw threads 2, 5 on the cables mesh with respective sides of the gearwheel means, and means operable to release at least one of the cables 1, 4 from driving connection with the shaft, the arrangement being such that operation of such means can permit one of the cables 1, 4 to be adjusted lengthwise independently of the other cable. As shown in Figs. 1 and 2 the two parts of the housing 7, 8 are connected by screws engaging in holes 13 in the part 8 and bores 14 in the part 7. Before assembly the cables 1, 4 can be independently adjusted. In the modification shown in Fig. 6 the cables 1, 4 are held in mesh with two gearwheels 21, 22. These gear-wheels are mounted on a bush 24 formed at one end of a driving- shaft 23 and are normally held in frictional contact with each other by a bolt 27. When the bolt 27 is loose the cables 1, 4 may be independently-adjusted. The bush 24 may be replaced by a screw-threaded stay-bolt provided with lock-nuts. |
