Question
« on: November 04, 2009, 10:53:08 PM »
Hello all I have a question in regards of a weight...

If one could get a single weight to constantly apply presure to a mechanism which causes the mechanism to lift that weight up, would this be somthing special? I know that if you compress a spring then place a weight on it and release the spring the weight will rise but thats the spring doing the work and not the weight, what i'm trying to ask is if one causesd a weight to lift itself by applying its own weight to a mechanism causing it to lift the weight up so long as it keeps that presure on the mehcnanism would this be anything special even if the answer to it was simple and logical...

The reason I ask this is because i "might" have a possible mechanism that can achive this and if it does i would like to post it here but i'm afraid that if i did and people saw how it works they would say "well of course its got to lift itself if you arrange it like that" and miss the point that it lifted itself without the need for other weights...

Anyway i would appreciate it if as many of you could answer my above question please, thanks

cheers, Alex

Hi Alex,

Yes, a weight lifting mechanism would be good to have in the toolbox. I needed one yesterday when my chainsaw bar got binded in a tree, If you could use the downward weight of the tree to lift itself just enough to get the saw out through self actuation that would be great. A self actuated lever/mechanism would come in handy.

The next question's would be:
Does this use any form of fluid displacement?
Is there any limitations on the type of object it can lift?
How fast would it rise?
Does it revert back to a lowered state once the weight is taken off?

For an example lets say I put a heavy steel ball on it, it lifts to a set height, a mechanism knocks the ball off would it go back to a lowered state once the weight is off?

Alex,

It's called 'bootstrapping' picking yourself up by your own boots!

If you do indeed have such a device, I am sure there is a lot of people that would be interested in it.

I have not heard from you! did you get my last e-mail?

Thanks everyone for your kind replies my mechanism design may have a fault i neeed yet again to overcome so i'm going to continue with my little project and see if somthing big comes out of it then i will post it here after getting some advice lol thats if the thing even works...

Also the weight once raised then taken off the mechanism, the mechanism should return to its original possition because the weight has been taken off

Cheers, Alex

P.S Ralph you will be recieving an enail from me soon and ill check out that address..

     Hi Alex, I think I know what your talking about. I ve been rolling around a similar idea in my head for about a month. I'm working out of town and I  wont be able to do any  experiments until I'm home on christmas holidays. If it works the way I think it will ,then as the weight comes up on the negative side of the wheel it will add to the wheels momentum. A positive force rather than a a negative. Like you I'll wait until I've had time to do some testing before making any claims

Sounds great! Keep us all updated and most of my mechanisms are not on a wheel but are rather like a mechanism you could put on a desk as a toy or something, i still have not built them yet but in time i will hopefully....
