Any Clues what this could be

[ladas]

Came across in the shed ....................

I haven't a clue what it is - or could be

..................any ideas ?

The patent number gives a clue, it was patented in 1907 as a 'duplicating machine' . No bloody idea what it duplicates. Whatever it did duplicate, we dont need two of anymore:D

Send it to the ABC collectors program for their "What is it?" segment.

Maybe a thing to measure or set trigger force on a hand gun?

Looks to me like the screw on the right hand bottom end holds something in place in the channel on the under side, the threaded bit on the left hand end is a length adjustment for whatever is being held.

And something pokes through the hole and rests against the wheel with the curve in it.

Or an early one of these-

Problem solved


Abstract

A file guide device for use in guiding a file in the operation of sharpening the teeth of saws and the like is disclosed. The device comprises a support member adapted to be fitted to a saw in a predetermined relation to the teeth thereof and a carrier member mounted to the support member for rotatably supporting a pair of rollers for guiding the file along axes corresponding to the angles of the cutting edges of the saw teeth. In one embodiment, the axes of the rollers are arranged in a fixed location with respect to the support member and are arranged so that the roller rotation plane is substantially horizontal. In another embodiment, one roller is movably mounted relative to the support member and is resiliently biased in a direction to move the file axis toward the cutting edge of a saw tooth.
