It's got a clock on it, a device on the back that turns at 1 rpm (it says) a punching device with a roll of tape and a line in that says signal. It's definitely a data logging device of some sort. Was it anything to do with the physics lab? Is it a deluxe tickertape machine?

I believe it to be a machine that is used to send a signal the school bells of to signal the end of lessons or end of the school day. On the front clock dial you can just about make out a smaller dial that is divided into the days of the week so that it wouldn't go off on the weekend. I guess that the signal socket is what connected it to the bell system, same as the fire alarm ones. I'm not too sure what the punch tape is for, it may hold the information for alarm or it could be what helps to regulate the time.

It's a primitive doomsday device. Standard issue to problem schools in the early 80's. If the working class oiks ran amok and no-one was available to reset it it would go off obliterating the school and preventing a more widespread uprising. The signal in is a remote failsafe in case any well to dos were still within the blast radius.
OK, honestly. It's the bell timer. The dial on the back has 'ring time adjustment' written next to it. No-idea what the recording ticker is for. Maybe just a very simple way of checking how much time has passed between rings, each hole is a minute and a punched hole indicates the bell went off.

it's pre '75 apparently, as the online digital records have no details of that registered design, apparently.

Accelerates protons to 7.8 Km/s and monitors the collisions.

We never had such 'newfangled' equipment at my (last) school in the mid 80s. The bells were rung manually from a switch outside the headmasters' office. I rang those bells many times (and not out of malice either before anyone suggests otherwise
