Abstract: 261,479. Ritchie, F. Aug. 20, 1925. Pantographic apparatus.-In a pantograph for transmitting written messages between two positions in an aircraft, the movements of a pencil at the transmitting end impart oscillations to two similar sectors pivoted at the sides of a conta,ining box, and wires &c. connected to the sectors are led to similarly arranged sectors at the receiving station and thus cause a writing instrument to reproduce the message. In the form shown a platen 4 is mounted in the containing box 1 and is adapted to be lowered by the pressure of the pencil 5 mounted in the holder 6. A rod 7 connected to the holder is pivoted to a lever 10 mounted on a pivot 12 so as to oscillate under the constraint of a spring 11, one end of which is fastened to the boss 14 of a sector 15 mounted on the pivot 12, the sector being thus caused to oscillate with the lever 10. A second rod 16 pivoted to the rod 7 operates on a similar lever 18 and sector 20. Wires 27, 30 secured to the sectors are led over guide pulleys 28, 29, 31, 32 to the receiving station. The pencil 5 is rotated through a small angle at each complete oscillation of the lever 10 by an arm 33 connected to the lever and to a lever 36, Fig. 4, carrying a pawl 38 which operates a ratchet 39 on the holder 6. The paper 40 passes from a spool 41 over the platen to a takeup spool 43, and is fed by a pawl 51 on a lever 4S connected by an arm 47 to a hand lever 44. A wire 55 secured to the arm 47 and passing over pulleys 57, 58 is adapted to produce similar movements of the paper at the receiving station. For transmitting the movements of the platen 4, the underside thereof rests on a screw 59, Fig. 3, mounted in the upper end of a pin 60, the lower end of which bears on one arm 67 of a bell-crank lever, the other arm of which is connected by a wire 70 to the corresponding arm of a similar device at the receiving station, the arrangement being such that when the platen at the transmitting station is depressed, that at the receiving station is raised. The front portion 71 c: the cover 2 of the box 1 can be drawn forward to provide an arm rest for the operator. In a modification the sectors are pivoted on the same side of the box and extend through slots therein so that they can be connected directly to the sectors at the receiving station. In this form the platens are fixed and the depression of the pencil at the transmitting end is adapted to produce a corresponding depression of the pencil at the receiving station. Specification 2237/15 is referred tc.
