Cutout relay and fuses - mechanical computing machinery

This photograph is of a Miniature Circuit Breaker or Cutout Relay - 4 contact type. The text on the back of this photograph reads:
Used in two places 1) As a guard on each group of T.I.M.s 2) As a cutout in the event of failure of drive etc on an adding unit.
The T.I.M.s mentioned are the Ticket Issuing Machines and the adding unit mentioned is one of several electro-mechanical shaft adders that totalled the investments made on a particular runner in a race.

This type of cutout relay can easily be seen in use at the top of the scanner panels shown in the previous photograph of the Photo Gallery, which are part of the Julius Totalisator installed at White City London. Click on the image to go to the Photo Gallery index page and select the image thumbnail above that for this photo, with associated text starting with A close up view of some of the scanners. I find it interesting that the company name Totalisators Ltd along with the amperage rating, is printed on the paper inside the glass casing of the fuses, visible on the right hand side of this photograph. There is a column of six fuses far right and two to the left of them, one aligned with the top of the column of six, the other at the bottom. Two of the fuses are oriented in the fuse holder in a position that makes the name clearly readable, namely "Totalisators Ltd". This was the UK associate company of Automatic Totalisators Limited. On the fuses of my time, the digital minicomputer based totalisator era, the current rating of fuses was stamped into one of the metal end caps mounted on the glass case and there was no paper inside. Of the two fuses that are oriented in a position where the current rating on the paper is legible, it reads upside down 5 AMP. These are clear to see by zooming in on the fuses.
