Abstract

533,462. Telephone sets; impulse transmitters. STANDARD TELEPHONES & CABLES, Ltd., (Schrieber, L. J. J., Lens G. X., and Gelberg, S. M.) Nov. 7, 1939, No. 29560. Addition to 501,696. [Class 40 (iv)] The parent Specification describes a hand set in which the calling dial is combined with the transmitter, and the present invention relates to detail improvements. The transmitter 37, 38 is removable without disturbing the dial mechanism, being mounted within a central concavity in the front of the dial mechanism, and supported solely upon a pillar extending therefrom. The transmitter and dial mechanism are supported by a base plate 1 and cup-shaped member 10 carried thereby. A pillar 7, rigid with member 10, supports at its upper end a conical member 31 having a collar 32 into which screws a ring 34 for removably securing the transmitter 37, 38. An extension d on the collar 32 serves as a finger stop. The finger disc 11 is riveted to a conical member 12 rigid with a sleeve 6 rotatable on the pillar 7. The fixed number plate 13 is held in position on the base plate 1 by a semicircular spring 14. The sleeve 6 carries rigidly therewith (1) a cam 17 controlling the impulsing contact, and (2) a toothed wheel 18 connected to one end of the driving spring 21 and connected through pinion 23 to a speed regulator 26. A push-button 42 controls a contact in series with the gravity switch, thereby enabling a second call to be made without depressing the cradle switch.
