Default Mystery object.

Found this in a garage clearance today. Can anyone tell me what the heck it is, please? Seems to be some sort of rev counter?

Tool to set up lathe cutting speed ? Presumably measures the linear speed of the material passing the cutting tool.

It's for the measuring cutting speed of a work piece held in a lathe. This will depend on the diameter/circumference of the work piece and the speed at which the lathe's spindle is rotating.

It's basically a high ratio step down gear box. The input is driven from the periphery of the work piece and the output shaft drives the pointers. Pressing a button engages the drive and three seconds later the drive is automatically disengaged. The cutting speed can then be read from the pointers, the scale being calibrated accordingly.

In the third picture a similar device seems to be being used to measure the speed of a band saw.

I've seen rev counters working on the same principle, but without the built in timer. You had to use a stopwatch
