The Bell Punch Analyser

The Analyser is a strange machine comprising a limited capacity Sterling currency adder and five separate counters.

On the right of the machine is an abbreviated keyboard (keys up to 5) with a column of keys for shillings, a column for pence, and a column with just two keys for farthings ( penny).
On the left are the five counters, each advanced by a single key.

The machine in the photographs displays the total: 99 19 11d.


A sales brochure (from about 1948) says of this machine:

It provides for :-

The Analyser appears to have been sold as a sub-part of the Automaticket ticket issuing system that was called Automacheckit.

The photograph here shows a Bell Punch Analyser fixed to a counter on a Bell Punch Automaticket display at an exhibition in 1952[1].

The sign says:


See the Automacheckit machines for Cash and Food Control.

There appears to be a strip of tickets going through the machines on the counter, including the guide at the rear of the Analyser, which can be seen in the photograph from the brochure, at the top of this page.

This is a very specialised machine and appears to be rather rare.
