Title: Improvements in or relating to time controlled electric switching devices
IPC: G04F3/02
Filed: 1938-01-17
Abstract: 509,437. Dropping loads from aircraft. SHEVLIN, J. T. (List, H.). Jan. 17, 1938, No. 1561. [Class 9 (ii)] [Also in Group XXXVII] In a device for the successive discharge of loads, e.g. from aircraft, a preselector lever 21 determines the number of loads to be discharged and an eddy current brake regulates the speed of movement of a spring-controlled contact arm la, which moves over a series of contacts 3, and thereby determines the time interval between successive discharges. The device is set by rotating a handle connected to the arm la till this rests on the first contact 3 and a pointer 5c points to point 1 of a scale. A spring is wound up during this process and the arm 1a held against return movement by a pawl 7 engaging a ratchet-wheel 6. The preselector lever 21 is then set till the desired number appears below a window 21a. To operate, a lever 8 is rotated. This serves first to close contacts 27 and complete a circuit to a releasing device 28<1> and secondly, by means of a pin 8b, to release the pawl 7. The switch arm 1a now slowly travels over the contacts 3 completing circuits to successive releasing devices 28<2>, 28<3>, &c. until a stop 5a fixed to the arm 1a engages a stop 21c on the lever 21. The contact arm 1a is now between two contacts, but when the preselector lever 21 is moved on again preparatory to releasing further loads, the pawl 7 allows the ratchet-wheel 6 and the arm 1a to move on till the next contact 3 is engaged. This ensures that when the switch 8 is again operated, a circuit will be closed immediately to release a load. The eddy current brake comprises a cylinder. 10 rotated by gearing in the annular gap 11a of a magnet 12. The cylinder is longitudinally adjusted by rotating a cam 17 by means of a knob 18.

[Also in Group IX] In a fibre lap winding machine (see Group IX), a braking torque is applied by two inductively coupled revolving members, separated by an air gap, one of which is driven at constant speed and transmits the torque to the other, the torque being controlled by variation of the magnetic flux between the two members. As shown, the coupling comprises a pole wheel, formed by a permanent magnet 3 and shoes 4, 5 and slidably keyed to a shaft 1 driven at constant speed, and a squirrel-cage armature 6. The facing surfaces of the pole wheel and armature are conical. To vary the flux, the air gap 5 between the member is varied by movement of a control rod 9 which acts via a lever 10 to shift the pole wheel on shaft 1. In another embodiment, both pole wheel and armature are cylindrical, the former sliding inside the latter, and the flux is varied by axially shifting the pole wheel to vary its depth of penetration within the armature. In another embodiment, the pole wheel comprises two or more magnets which can be relatively angularly displaced about the pole wheel axis to vary the flux. In a further embodiment, the pole wheel comprises an electromagnet and the flux is varied by varying the magnetenergizing current.

Abstract: 306,259. Thomas, E. Jan. 24, 1928. Clutches, free-wheel.-A friction clutch which allows slip in either direction on attaining a certain torque may be used to drive in one direction only. A cone 6 fast on one shaft 6<1> is biased by springs 7 and ring 8 to engage an internal cone 5 loose upon a boss 1 which is fast on the other shaft 2. The boss 1 is integral with a radial fork 1A which engages the heel 4C of a three-armed lever 4 pivoted on a pin 4B carried by the cone 5. The other arms 4A of lever 4 engage the ends of strut pins 9 secured to ring 8. The torque passes through fork 1A and heel 4C, and, when large enough, separate the ring 8 and cone 6 from cone 5 against springs 7, causing the clutch to slip. By making the lever arms 4A unequal, the limiting torques in the two directions of rotation are rendered different. By making one arm 4A long, and the other short, the clutch transmits in one direction and slips in the other
