Title: Improvements in and relating to mechanism for use in dropping bombs from aircraft
IPC: B64D1/04
Filed: 1938-11-12
Abstract: 522,565. Bomb - - dropping. ARMSTRONG, J. J. V. (Vickers, H. F.). Nov. 12, 1938, No. 32971. [Class 9 (ii)] Mechanism for use in dropping bombs from aircraft comprises a latch means for normally holding the bomb in position, a relatively strong spring for positivly holding said latch means in position until release is desired, kinetic energy storing means and control means adapted momentarily to connect said energy storing means with said latch means to overcome said spring. As shown in Fig. 1, straps 3 on the bomb 2 are normally supported on latches 5 on -a member 4, the latches being pressed against stops 6 by a strong spring 7. Closing and opening of the member 4 is controlled by a pivoted lever 8 connected by a rod 9 through reduction gearing 12 with a very.small fly-wheel 11 driven by a high speed motor 10. One of the reduction gears 13 is preferably connected to a pinion 13a through a " one revolution " clutch member constructed as shown in Fig. 2. In this arrangement, the gear 13 and a ratchet clutch 15 carried by the shaft 14 rotate continuously as long as the motor 10 is in operation. A cam and ratchet clutch member 16 is slidably keyed to a shaft 17 carrying the pinion 13a, a spring 19 normally urging the clutch member 16 to the right. The clutch member 16 is, however. normally restrained from engaging the clutch member 15 by a lever 20 which is free to rotate about a shaft 21 but does not slide longitudinally of this shaft. On depression of a control lever 22, a cam rod 23 'is pulled rearwardly and engages the lower end of the lever 20 so as to rotate same in a clockwise direction about the shaft 21 thereby freeing the member 16 and allowing the clutch parts to engage and cause rotation of the shafts 17 and pinions 13a. Due to the arc of movement, the lower end of the lever 20 will slip off the rod 23 as the movement of lever 22 is completed and be returned to its normal position by a spring, the upper end of the lever bearing against the cam on member 16 and causing disengagement of the clutch parts on the completion of a single revolution. Instead of employing a lever 22, the clutch may be actuated by a solenoid 30, Fig. 1, controlled from a remote point 31. The pinion 13a of the gear 13 and the gear of the rod 9 are so meshed that when the clutch mechanism stops, the gear of the rod 9 will be in either of two extreme positions, that is, the lever 8 will be moved either to the right to latching position or to the left to releasing position. Thus, a first actuation of the lever 22 or solenoid 30 to actuate the clutch will move the lever 8 to release position and stop, whilst a second actuation of the parts will move the lever 8 back to the normal latching position.

Abstract: 464,151. Railway-stops. WHITE, J. W.. and LOWE, C. S. Nov. 28, 1935, No. 32995. [Class 104 (ii)] A wagon stop comprises a pivoted catch 7 adapted to drop into engagement with a pin 8 on the wagon and to be disengaged by means of an axially movable rod 11 connected thereto by a link 12. After the catch has been raised further movement of the rod 11 brings a gravity pivoted finger 14 into contact with the pin 8 or other part of the wagon and imparts a forward thrust to start the wagon. The downward movement of the catch may be assisted by a pivoted weight 9 connected thereto by a link 10. The rod 11 may be moved by pneumatic, hydraulic, or electric power under remote control, or the hydraulic &c. means may be actuated consequentially to the closing of the discharge valve of a hopper used for loading the wagon.
