Title: A transmission mechanism provided with a release device, for converting a rotary movement of a driving means into an axial displacement of a driven member
IPC: F16H25/20
Filed: 1963-07-05
Abstract: 1,044,216. Screw-and-nut gearing. R. HALLER. July 5, 1963 [July 7. 1962], No. 26690/63. Heading F2Q. Rotation of a screw shaft 5 effects axial movement of a coupling rod 22 secured to a tubular member 14 within which nuts 8, 9 are located and prevented from rotating on the screw shaft 5 by the tightening about the nuts 8, 9 of a cylindrical clamping spring 33, the ends of which are secured to a link 36 located in an axial slot 35a formed between the ends of a sleeve 35 secured to the tubular member 14. The ends of the link 36 are formed with projections 36a, 36b, 36c, 36d which are adapted to co-operate with inclined surfaces 37a, 37b, 37b<SP>1</SP>, 37d defining the axial slot 35a. The nuts 8, 9 are located centrally within the tubular member 14 by springs 16, 20 acting on ball-bearings 12, 13. The tubular member 14 is constrained to move axially within an outer casing 1 by an axial guiding rail 32. A sleeve 10 may be disposed between the spring 33 and the nuts 8, 9. On rotation of the screw shaft 5, friction causes the nuts 8, 9 to turn, the link 36 to tilt, and hence tightening of the spring 33 to prevent rotation of the nuts 8, 9, thereby establishing working relationship between the screw and nuts, resulting in axial movement of the rod 22. If movement of the rod 22 becomes obstructed, the assembly of nuts and spring 33 continues its axial movement, compressing one of the springs 16 or 20, until the projection 36a or 36c slides out of the slot 35a, thereby releasing the clamping spring 33. Alternative forms of the link 36 are shown in Figs. 4 and 5.

Abstract: 861,342. Raising masts. FONDEN, P. B., and WALANDER, K. O. T. Aug. 5, 1959 [Aug. 28, 1958], No. 26734/59. Class 78 (2). [Also in Group XXXIII] Means for raising and lowering an aircraft arresting net 5 suspended from a horizontal cable comprises two main cable supporting masts 3, 4 adapted to be raised and lowered in such a way that the horizontal cable is raised and lowered vertically, and between the main masts, one or more auxiliary masts 6, 7, connected to the cable at their upper ends, their other ends being displaceable along the ground parallel to the cable in conjunction with the raising and lowering of the main masts. Each end of the net is connected to a braking mechanism 1, 2. The foot of each auxiliary mast is pivoted to a tandem wheeled carriage 8 connected in a cable run 10 wound on to drums 18, 19 driven through a clutch 17 and gearing 16 by a motor 9, which also drives a drum 14 and cable 15 for raising and lowering the main masts. The cable 10 is looped around a pulley 11 biased to the full line position by a cable 22 wound on a drum 23 biased to wind in the cable by spring means 24. Should the carriage 8 become halted during the netraising operation (cable 10 moving in the direction of the arrows), pulley 11 becomes displaced to the broken line position. During the netraising operation, the part of cable 10 between the carriage 8 and drum 19 is held taut by spring means 20, inoperative during the net-lowering operation. For the net-raising operation, clutch 17 is initially disengaged, the motor 9 raising the main masts only through cable 15. At a predetermined point, clutch 17 is automatically engaged, and the auxiliary masts start to rise, so that all masts reach the fully-raised position together. During the net-lowering operation, clutch 17 is initially engaged, and all masts are lowered together. When the auxiliary masts reach the lowered position, clutch 17 is automatically disengaged, and the lowering of the main masts is then completed. In a modification, both ends of cable 10 are wound on a single drum replacing drums 18 and 19, and the shorter cable run between the drum and carriage 8 contains a tensioning device.
