TELEPHONE No's 115 and 115A


A wall telephone with prepayment coin collecting box used on call offices in Manual (Central Battery) exchange areas.

This pay phone was introduced circa 1924 and used a Box, Coin Collecting No. 13.

The telephone comprises of a backboard, with a transmitter mounted at the top.

The Box, Coin Collecting No. 13 is also mounted on the board and has a bell receiver that locates on switch hooks, fitted at the top left hand side of the casing.

This telephone was used with a Bellset No. 1 and a Relays & Coils No. 29AN, which were fitted, together with the Telephone No. 115, to the kiosk backboard (see drawing 2305).

Fitted with a Lock No. 31 (Engineering cover) and a Lock No. 4 (Coin box cover).

The  Transmitter No. 1 could have a Label No. 43A fitted between the speaking tube and the transmitter body.  This label advised of the Exchange name and number.

If emergency call facilities were required, then a Press Button "G" would be fitted in the kiosk backboard.

The Telephone No. 115A differs in having a returned coin chute trough at the bottom of the containing box (Box Cash No. 5) and extending along its whole width, surmounted by a plate glass front approximately 4.5 inches in depth. These telephones are installed in localities where fraud is found to be prevalent through criminally inclined persons blocking up the returned coin chute with paper, thus preventing Callers from obtaining the return of coins after making an ineffective call, see following Paragraph, and enabling the money to be dishonestly collected from the trough later on the removal of the paper.
