Public Coin Box using
Boxes, Coin Collecting No. 1


This Coin Collecting box was introduced just as the National Telephone company merged with the GPO in 1912.  The GPO modified the box slightly and it finally became the Box, Coin Collecting No. 1. 

This was a flimsy box and can be forced open easily, so armoured cash boxes were installed positioned under the case.

It accepts 1d coins and when they were deposited, on the instruction of the telephone operator, and the knob turned a buzzer circuit operated.  This allowed the telephone operator to count the number of coins inserted.

The box is made of tin plate box and painted black.  A hole in the front engages on a brass peg and with the addition of a padlock allowed the front to be secured.  On the inside of the front, above and beneath the hole are two metal strips.  Each strip has two holes that have been tapped with a thread. It was possible that a lock was fixed on the inside of the front to secure it instead of the peg arrangement.

On some boxes the front is embellished with a decorative angular boarder in gold paint. At the top of the front is a text panel of instructions:-

USE OF COIN COLLECTING BOX.
WHEN REQUESTED, BUT NOT BEFORE,
INSERT ONE PENNY, OR MORE, AS
DIRECTED BY THE TELEPHONIST, INTO
THE SLOT, AND TURN THE DISC.
INSERT ONLY ONE PENNY AT A TIME
AND TURN THE DISC AFTER EACH
COIN HAS BEEN PLACED IN THE SLOT.

MIS-SHAPEN PENNIES MUST NOT BE USED

Below the text is the royal crest and below that the words: "GENERAL POST OFFICE" in black, on a gold coloured ornate panel.

On the top is a coin slot made of metal (likely to be brass).  This is secured to the case by three machine screws.  These screws also secure the coin discriminating mechanism to the underside of the top.

On the right-hand side, a knurled knob extends from the mechanism.  When turned in a clockwise direction, as indicated by an arrow, a coin inserted in the slot is deposited into the box.

The mechanism contains a pair of contacts to operate a buzzer.

A circuit diagram is affixed to the inside of the front cover and this shows the electrical operation of mechanism and also indicates that the manufacturer was B.L.M.E. Co. Ltd of Beeston.

This box was used with a Telephone No. 1 in CB areas or a Telephone No. 3 or 11 in LB/Magneto areas.

After merging with the National telephone Company, the GPO fitted an enamel overlay on the existing No. 1's.
