Box, Coin Collecting No. 705
The Boxes Coin Collecting No. 705 was the pay on answer payphone, designed for use with subscriber trunk dialling (STD), in public kiosks. It was made by Associated Automation, part of the Elliott Automation group of companies and was intend for use in public call offices. A more compact offering was used for privately rented payphones, using a Telephone No. 711 and a CCB No. 700 coinbox, mounted on a wooden back board. A technical description can be found in the IPOEE Journal (Vol 51, January 1959, page 343).
The original BCC No. 705 (shown to the right) was relatively easy to break into, especially in remote places. For these reasons an armoured version of this coin box was then produced and all the original models replaced in the early 1970's.
The main difference in the two is that the armoured version is heavy gauge steel, originally painted grey, but later painted black, and had a cash box cover that slid upwards to allow removal of the cash box. The cash box area also protruded out at the front about one inch. The armoured version used the Lock No. 42 for the mechanism cover but still retained the Lock No. 6 for the cash box cover.
Although the later version greatly reduced break-ins, people then started to remove the whole unit by smashing the rear of the telephone box, with sledge hammers, in an attempt to release the fixing bolts. Another problem was that the protruding cash box became a urinal for drunk individuals and this tended to seize the cash box cover lock, which was situated in the very bottom of the cash box.
