Title: Improved apparatus for selectively sending pre-arranged electric signals
IPC: H04L15/22
Filed: 1917-06-08
Abstract: 195,100. Low, A. M. June 8, 1917. Impulse transmitters. -In an impulse transmitter of the type having a number of signal discs each of which can be released from a stop by depressing a corresponding key, the disc is brought to rest by a second stop after sending its signal, and is again released when the key is let go, whereupon it sends an annulling signal and completes its revolution to normal position. The apparatus is particularly for use in radio-control systems, the different discs sending 1, 2, 3 &c. impulses followed by a prolonged annulling impulse. Each disc 1, Fig. 2, is spring-pressed against a collar on a constantly rotating shaft 7 so that when a key 36 is depressed to remove a stop-arm 32 from a pin 31, the disc rotates .counter-clockwise and transmits impulses by operating a pair of springs 19. The disc is brought to rest by the arm 32 engaging a second pin 39, but is released again when the key is let go. in the modification shown in Fig. 4, two signal discs are fixed to each of the sleeves 46, 47 and either sleeve can be moved to left or right on its shaft to disengage a stop-arm 61 or 62 from an abutment on the casing, the same movement bringing one of the discs into a position in which it operates the contact lever 63. The liberated sleeve and discs are rotated through a friction clutch until a pin 69 on the operative disc engages the abutment on the casing. When the sleeve is restored to its central position, the pin 69 disengages itself and the sleeve and discs complete their revolution to normal.
