Title: Improvements in or relating to sound intensity regulating devices
IPC: G10K1/064
Filed: 1957-11-21
Abstract: 820,298. Bells. TELEFONAKTIEBOLAGET L. M. ERICSSON. Nov. 21, 1957 [Dec. 13, 1956], No. 36316/57. Class 13. In a mechanical volume control device for a polarized alternating current bell, the two arms of a hairpin spring 5, resiliently mounted on a base-plate 1 by means of lugs 4 and collar 3, have their free ends 9 outwardly bent so as to intersect a plane in which the striker rod K of the bell oscillates, and a stud 6 of rhomboid crosssection, which is disposed between the arms of the spring 5, is rotatably mounted upon the baseplate 1, rotation of the stud 6 varying the separation of the arms of the spring 5. The stud 6 is integral with and projects centrally from the smaller end of a frusto-conical member 6a formed integrally with one end of a cylindrical stem 6b set into an aperture in the base-plate 1, and secured to a control knob 6c disposed beneath the base-plate 1. The arms of the spring 5 are biased against the conical surface of member 6a and the entire stud assembly is resiliently secured to the base-plate 1, a resiliently arched plate 8 forming a collar surrounding the stem 6b and a washer 7 partially surrounding the stem 6b and located in a groove 6d therein being interposed between the baseplate 1 and the conical member 6a. A slotted screw head in the control knob 6c facilitates easy turning thereof within a range limited by two stops. The mechanical volume control device is fitted to the bell mechanism of a telephone set by loosening the two screws S which secure the bell to the base-plate of the set, interposing the base-plate 1 of the device between the plates F of the bell and the base-plate of the set, and screwing up the screws S again. A hole is provided in the base-plate of the set to allow access to the screw head in the control knob 6c. In operation the striker rod K strikes the free ends 9 of the spring 5 prior to impact of the striker head on the bell, the oscillatory movement of the rod K being thus damped. The free end 9 of the spring 5 which is struck by the rod K will move outwards and downwards on the conical surface of the member 6a, and the substantial frictional resistance to the movement of this arm on the conical surface ensures that when the rod K again moves inwards the arm follows it with a delayed movement so as not to impart an impulse to the striker rod K. The conical member 6a may be dispensed with by providing each arm of the spring 5 with a nose-portion 10 (Fig. 3A) bearing frictionally against the base-plate 1. The hairpin spring 5 may be replaced by two separate wire springs or other resilient members bearing frictionally against a base-plate.
