Advice on building s simple ‘clutch’ to stop a driven accessory
Jim Dobson:
I’m after some advice to build a simple ‘clutch’ that can be activated by a lever to disengage a running accessory that is being run by a belt off an engine.
If in the photo below where I have drawn the red line (and that belt was longer) what type of simple ‘clutch’ could be built to be able to work to disengage the belt with a lever moved one way and then re-engage the belt with the lever moved back? This would be an extremely handy thing for me to have when running accessories of steam engines and H&M engines etc
I’ve wracked my brain and everything I have come up with would be a dud……any ideas?
Hope I’ve made some sort of sense with the above!
awemawson:
A tensioning pulley in the drive train mounted on an “over centre” crank that can either tighten or slacken the belt much like a flat belt overhead drive shaft would be in an Edwardian workshop.
BillTodd:
Or maybe roll the belt onto a free-wheeling pulley?
If you wanted a stand-alone clutch unit then a floating pulley that could be forced into contact with a moving one or a stationary block could give you both clutch and brake.
timby:
I am old enough to have worked in a steam sawmill, a "fast and loose " pulley as described by BillTodd was usually the choice to stop a drive but I like awemawson's idea better, a jockey pulley on an arm might look better.
Jim Dobson:
A big thanks for all the replies, much appreciated. If I can fabricate one up, this would immensely increase the pleasure I get from running small accessories of my variety of engines…..again thanks all.
Someone went to the trouble of cobbling this together to show me a way - Super appreciated!!! :beer: :bow: :bow:
