Title: Regulating apparatus for operating from a distance devices for releasing projectiles from aircraft
IPC: B64D1/04
Filed: 1927-07-11
Abstract: 295,808. Alkan, R., and Lesourd, G. July 11, 1927. Dropping bombs.-Bomb-dropping apparatus controlled from a distance and adapted to drop the bombs either singly each time a trigger or the like is operated or in a series at regular intervals, has a main shaft, rotation of which under the influence of a spring or other motor effects the release of the bombs, and three pawls engaging an abutment on the shaft to control its rotation, one pawl being hand operated, while the other two control respectively the number of bombs dropped in a series and the time interval between successive bombs. As shown in Fig. 1 the bombs 1 - - 1" are held by arms 3 - - 3<11> adapted to be released in succession when a shaft 2 is rotated' by a rubber spring motor 9. The shaft 2, a main shaft 21, Fig. 2, in the controlling mechanism, and the motor, are connected by chains and gearing so that a bomb is dropped for each complete revolution of the shaft 21. The rotation of the shaft 21 is controlled by three pawls 26 - - 28. The first pawl 26 is directly operated by a trigger 30. The second pawl 27 is operated by a notched disc 33 on a shaft 34 geared to the main shaft 21 and controls the number of bombs dropped in a series. The shaft 34 is driven from the main shaft by a Maltesecross device, and a detachable coupling 39, 40 is provided' so that the shaft 34 and disc 33 carried thereby can be angularly adjusted according to the number of bombs to be dropped in a series. The third pawl 28, for determining the time interval between successive bombs, is connected to an arm 49 bearing on a slow moving cam 50 formed with a projection 50<a>. The cam 50 is carried by a drum 51 rotatably mounted on the shaft 21 and connected thereto by a spring so that it tends to rotate with the shaft, but is constrained to move at a slower rate by gearing 52 - - 55 and an escapement 56. In a modification, a centrifugal regulator is provided instead of the escapement device, and in another modification the tension of the spring in the drum 51 can be regulated. To discharge a series of bombs, the disc 33 is set to the required position with the arm 27<a> of the pawl resting on the periphery of the disc, and the trigger is pulled and held back. The shaft 21 then quickly rotates and a bomb is dropped. The shaft after one revolution is held by the pawl 28 which is released when the cam 50 completes one revolution. The operations are then repeated until the arm 27<a> of the second pawl drops into the notch in the disc when the pawl 27 engages the shaft 21 and prevents further rotation.

In a vehicle signalling system, the clearance lamp group 20 or 20<SP>1</SP> on the appropriate side of the vehicle is flashed at an increased level of illumination to indicate a turn. At night, switch 10 is placed with handle 19 in the position shown and both groups of lamps are illuminated at a low level by connections extending through switch arms 16, 17 and resistors 23, 23<SP>1</SP>. To indicate a left turn, the arm is moved clockwise through one position, the connection to group 20 then extending through arm 13 to contact 21 and that to group 20' through arm 14 and contact 31<SP>1</SP>. Group 20 continues at a low level whilst group 20<SP>1</SP> is illuminated at a high level and flashed intermittently by a flasher unit 30<SP>1</SP>. To indicate a right turn the arm is moved in the anticlockwise direction where group 20<SP>1</SP> continues at a low level whilst group 20 is flashed at. a high level by flasher 30. Tell-tale lamps 25, 25<SP>1</SP> are operated from relays 40, 40<SP>1</SP> in series with the flasher units. For day operation, switch 15 is reversed by placing handle 18 in the uppermost position. Contacts 20, 21<SP>1</SP> are no longer engaged by arms 16, 17 and the lamp groups are only connected in circuit when a turn is signalled. Preferably, arm 14 is so designed that when the switch is in the "day" position, the arm 14 will not engage contact 21 or 21<SP>1</SP>. To indicate an emergency stop, the switch is rotated through two positions until contacts 36 and 36<SP>1</SP> are engaged by arms 13 and 14 whereupon both groups of lamps are flashed at the high level.
