Patent GB-263970-A (GB)
Title: Improvements in or relating to ammunition hoisting or conveying apparatus for ordnance
IPC: F41A9/05
Filed: 1925-10-21
Abstract: 263,970. Vickers, Ltd., Pearson, E. C., and Ritchie, J. Oct. 21, 1925. Loading-appliances. - Relates to ammunition hoists of the kind described with reference to Figs. 35 to 37 in Specification 229,986, in which a two-part oscillating flash-tight scuttle A is employed, one part a being opposite a loading aperture a<x>, whilst the other a<1> positions the ammunition C in the path of conveyer heads D. These heads are mounted on a continuously-moving endless chain mechanism D<1>, which also drives a drum E having a cam slot e for imparting the oscillatory movement to the scuttle through the medium of a clutch. According to the present invention, the cam slot imparts intermittent oscillatory movement to a pinion a<2> having clutch teeth engaging recesses a<3> in a collar A<3> which drives the scuttle. The clutch is moved to operative position by pressing down a hand-lever G, which through a bell-crank lever g moves a sleeve G' and thereby compresses two springs g<1>, g<3>, the inner one g<3> of which acts upon a bolt g<3> simultaneously to unlock the collar A<3> and automatically engage the clutch when the pinion reaches the timed position for the scuttle to be moved. The hand-lever is held in displaced position by a retaining latch G<5> on the sleeve, which engages a rim a<5> of the, collar. As soon as the scuttle commences, to move, projections a<6> on the collar depress the latch G<5> and the bolt G<3> then rides round the periphery of the collar until the scuttle has made half a revolution, when the bolt, under the action of the outer spring g<1>, enters a recess so as to lock the scuttle and return the clutch and hand-lever to the vertical or inoperative position.

Title: Improvements in or relating to backlash eliminating means in control mechanisms
IPC: B64C11/36
Filed: 1954-09-15
Abstract: 776,368. Fluid-pressure servomotor-control systems. UNITED AIRCRAFT CORPORATION. Sept. 15, 1954 [Sept. 15, 1953], No. 26739/54. Class 135. [Also in Group XXIV] In a control system for setting the pitch of the blades 30 of the forward rotating hub 26 of a dualrotation propeller unit in accordance with the pitch for the blades 28 of the reverse rotation hub 24 a valve 60 controlling the supply of hydraulic fluid to a motor (not shown) for adjusting the pitch of the forward rotating blades 30 is mounted in the hub 26 of the blades 30 and is operated by relative rotation of a sleeve member 84 thereto. This sleeve 84 is connected to a synchronizing ring gear 56 for the reverse rotating blades 28 through gearing 66, 68, 70, 74, sleeve 78 and reversing gears 80, 280, 286, 292, 82 so that it normally rotates at the same speed as the reverse hub 24 but in the opposite direction, i.e. at the same speed and in same direction as the forward hub 26. The control valve 60 is thus normally maintained in a neutral position by a tooth 86 on the sleeve 84 engaging a notch 158 (see Fig. 2), in a pivoted plate 88 which actuates the valve through a helical spline device 86. The plate 88 is loaded by a spring 152 coupled to a lever 178 of a gear 154 meshing with quadrant teeth 156 on the plate so that over the central range of control the backlash in the gear trains is maintained in one direction to prevent hunting effects. If the pitch of the reverse blades 28 is changed the sleeve 84 is moved relatively to the hub 26 and the control valve 60 is moved from its neutral position to operate the pitch-changing motor (not shown) of the forward blades 30 in the desired direction. In order to provide a follow-up action from the forward blades to the control valve 60 a synchronizing ring gear 110 for the forward blades 30 is connected through gearing 114, 116, 118, 130, 134, sleeve 136, reversing gearing 138, 300, 310, 140 and sleeve 142 to the reverse rotating hub 24. A housing 150 containing the reversing gears 300, 310 and also the reversing gears 280, 286, 292 of the control train is normally stationary but is adapted upon adjustment of the pitch of the forward blades to rotate a small amount to return the sleeve 84 and control valve 60 to neutral position with respect to hub 26 as the blades 30 attain the desired pitch position.
