Title: Improvements in or relating to radio-receiving apparatus
IPC: H03J3/12
Filed: 1938-07-23
Abstract: 506,113. Wireless receiving-apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' CLOEILAMPENFABRIEKEN. July 23, 1938, No. 21940. Convention date, July 26, 1937. [Class 40 (v)] The tuning spindle 1 of a radio receiver may be coupled either to the tuning condenser or a change over switch 14, according to whether tuning is in progress or a station is being received. The member 4 is mounted so as to slide freely along shaft 1 by means of the slot 3 and comprises toothed members 5, 6, respectively engaging rubber discs 7, 8 whereby the motion of knob 2 is imparted either to the tuning condenser by the pulley 9 and cord 10 or to a shaft 11 which operates the switch 14. The member 4 is free to rotate with respect to a sleeve 17 to which is pivoted a lever 16 also pivoted to the chassis at 15 and constrained to urge member 4 into engagement with the tuning pulley 8, 9 by a spring 18. The lower part of 16 is formed as shown in Fig. 3, with an aperture 26 and a pair of arms 21, 22, the aperture being engaged by the shouldered end 35 of a lever 33 actuated by armature 28 and electromagnet 27 in dependerice on received signal strength. Lever 33 is pivoted at 32 and held by spring 34 against a stop-member 30. On the rectangular shaft 11 are mounted a cam-disc 12 shaped as shown in Fig. 4, and a locating or click disc 13 shown in Fig. 5. While tuning is being carried out, the lever 16 is positioned as shown in Fig. 1 ; as soon as a signal of predetermined strength is timed in, device 27 is energized and lever 33 rotates about pivot 29 to engage aperture '26, thereby forcing lever 16 into the dotted-line position, disengaging the drive to pulley 9 and engaging it to the shaft 11. At this moment arm 16a can pass cam 12, one of the portions 37 coinciding with its path. Farther rotation of knob 2 operates switch 14 to remove the muting and de-energize magnet 27; lever 16 is now prevented from returning to its first position by arm 16a which is now engaged by one of the projecting portions 36 on the cam 12. To tune in another station the knob 2 is still further rotated to operate the '' search " or tuning switch; lever 16 is released by cam 12 but owing to operation of the " search " switch, magnet 27 is again energized by the station to which the set is still tuned. Lever 33 thus swings over to the right, but can now pass between arms 21, 22 of lever 16 which latter is now free to return to the original position under action of spring 18. The cycle of operations may then recommence with tuning.
