Title: Improvements in or relating to automatic telephone dialer
Inventor: KILBURG JAMES
IPC: H04M1/274
Filed: 1953-10-13
Abstract: 736,135. Impulse transmitters. KILBURG CORPORATION, J. Oct 13,1953, No. 28143/53. Class 40 (4). A clutch interposed between an impulse transmitter and its driving means is controllable by independently operable selector mecharnisms, one of which includes a tape-like member with coded perforations therein, to produce series of impulses representing different numbers. As shown, Fig. 1, to control the transmission of seven-digit numbers there are provided seventy dogs 35 arranged in seven groups often. A dialtype impulse transmitter 16 is driven by a motor (not shown) through a cable 21 and a shaft 25 until one of the dogs 35 enters a slot 31 in a drum 30, releasing the clutch so that the.dial 16 runs back and takes the shaft 25 with it, engaging a second clutch to step an outer drum 39. The slots 31 are arranged in seven helical groups of ten, so that the entry of a dog 35 stops the dial at the correct point for transmitting the digit corresponding to that dog. Seven larger apertures 40 are disposed helically round the outer drum 39 which is rotated through one step at each digit so as to admit a dog from each group in turn. The stepping of the outer drum 39 pushes out the previously advanced dog so that the inner drum 30 is returned to its initial position together with the dial 16 and shaft 25. A spring returns the outer drum 39 to its initial position when it finds no dog 35 advanced. The dogs to be advanced, and hence the digits to be dialled, are selected by any one of three means, as follows. (1) Perforated tape 10, Fig. 1. The name of the wanted subscriber, inscribed on the tape, is arranged to be opposite a window when the corresponding perforations are under the dogs 35. The apparatus includes punches for perforating the tape 10. (2) Keyboard, Figs. 2 and 3. Depression of a key causes its stem 51 to push a plate 46 sideways so that notches 50 are positioned under the corresponding dogs in all the groups. Latches 54, Fig. 3, of which there is one for each group of dogs, are retraced one at a time by depression of the keys so that only one dog is advanced at any one time. (3) Single key depressed for whole sevendigit number, Fig. 3. The key stem 62 pushes a corresponding code plate 60 so that notches 70 are placed under the required dogs 35 and all the latches 54 are retracted. The dial 16 may also be used normally, either directly or by means of an extra finger plate (not shown) connected through a one-way clutch to the dialling finger 19.
