help with identifying some objects

[cymelbushby]

these came in the box with my lathe but i really do not know what they could be
there are 2 both the same only indicating marks is a67 on it

Never seen anything like them. Nothing to do with a wood turning lathe that I have ever seen. Threaded connector for air presumably.

 

[cymelbushby]

I didn’t know if something to do with vacuumed chuck

Some sort of pressure activated rams to lift or make adjustments.
The black bits folding over onto the top of the rams to give indirect connection.

Foot operated switch?
Don't look used, easy to change the threaded socket to any of 4 positions.
Take one apart, are there electrical contacts in there?

its just a air push switch no electrical connection but could be modified to emergency stop i suppose

Take more pictures and stick them on evilbay - someone'll know what they're for.

 

[MusicMan]

could you stand them up on their feet, back off a bit and let us see them as a whole. And what make and type of lathe is it?

 

[cymelbushby]

My lathe is a woodwise 28-40
Immaculate condition as never been used
There were in the box wrapped same as some other bits of lathe
