Actuators/Hydraulics

Hello wheels always turning

What you require appears to be a modified pair of car hydraulic jacks.

These could do what you are asking, unless I have misunderstood your situation.

A picture is worth a thousand words, but if you intend patenting your invention, you would not be able to publish any part of it, because then no patent would apply, due to "Prior Publication".

Kind Regards....

Hello again, wheels always turning

Common Saying:

"A picture is worth a thousand words" is a phrase or saying which describes easily a situation.

So....you could describe something in words, but the more complicated the thing you are describing, the greater number of words are used in that description.

So....A picture of the article is far better, along with a few words.

Then all can look at the picture, and the few added words finish off the description.

Thus, to properly describe a motor-car, in words that included all specifics, would take millions of words, right down to details such as the characteristics of the tip of a sparkplug and more.

But if you showed a picture of that car, most viewers would know straight-away what sort of a car it was.

Patents and Publishing:

If parts of an article or thing are publicly published (such as in Newspaper, TV, Radio, Internet, CR4 Forum, etc.), then later if the inventor tries to patent that article or thing, and actually obtains a Patent, if another person or Company uses that part of the design which has already been published before the Patent Application was made, there is no redress or recourse against that person or Company who uses the design part which was Published prior to the Patent Application.

Example:

I design a new sort of light bulb, which includes using metallic glass as the filament.

I unwisely tell a friend and show him a picture of it, or the lamp itself.

The friend decides to place a picture and/or a description of my design on a public Internet site - for example, the CR4 Forum, which is a public site.

I get advice and assistance from others on that site, improve my design, and obtain a Patent.

I start a Company which makes those new lamps by the millions,. and for a short time, become wealthy.

Then I discover that other Companies start up, making the same lamp I invented.

I foolishly put myself into the hands of lawyers, try to sue those other Companies for "Patent Infringement".

I lose the case, because of "Prior Publishment" of my design, or part thereof.

I become bankrupt, my wife leaves me, I become an alcoholic, and even the family dog goes elsewhere to live, after I try to move into a new home

OK....Now do you see.

Trust that assists you

Hey Sparky,

It seems to me that you genuinely and honestly could and probably would help me if able to. So, I'm going to hope you're a good influence.

Anyway cut to the chase right? I still want to know about the last reply. Although, I got to thinking......I do have a "poor-man's patent" on my invention. Don't know if you've ever heard of the term. I learned it in art college years ago. If you know of it, would that over-ride the rule you told me of?

O.K., now to the main chase. To better describe my earlier explaination without totally submitting idea............Imagine you have a standard '''push" lawnmower or rotertiller that just hurts for you to operate due to being extremely taller than the average human. Then cutting both side tubes of "push"handle and putting dual hydraulics there, and then returning the original upper half of "push" handle back on.

Then, adding (within reach) an approx. 3" lever or handle to pump when tall person is operating to match a height for comfort. Then when a family member of short or average height wanted to operate, they'd just turn the knob (approx 1" diameter 1/2" height) to release and lower back to original height.

Why not use the pushbutton style of extending telescoping tubing like one finds on lots of things such as adjustable metal crutches, walkers, table legs, etc?

Well, that thought crossed my mind when I first came up w/ my idea. But, for the application I'll actually apply my idea has to be hydraulic. I just used the handle of a pushmower for a close visual comparison for what I'm actually making.

O. K.

You state: "Also, the setup wouldn't have to hoist anymore weight than the original strength of metal tube/pipe would be as a whole. (Before cutting pipes and inserting actuators in center."

Did you mean weight instead of "strength?" In that case, the hydraulic pressure would not have to be very high and would not necessarily need to be metal. Have you considered making your own cylinders with the telescoping tubing you intend to use?

Newcomers are made welcome here. Please 'chime in' and help others too.

Have you tried web searches at sites like globalspec.com or mcmaster.com or thomasnet.com?

Doing searches for hydraulic jacks could yield good results.

Hello wheels always turning:

and welcome. Is this the first time you have been here?

Can I just refer to PWSlack's remark in post '2', and your reply............

I think you saw an insult where there was none. It was a friendly remark.

If you have a special talent or interest and, think you could help by giving your own advice, please do so and become a helpful member where and when you can.........and, of course, only if you want to?

Everyone is hear to help or be helpful. That is why this great site exists, OK?

stay safe

Wheels,

What you describe is essentially what you also ask for as potential actuator.

Just visualize your too tubes as hydraulic cylinders or at least the ends of them as hydraulic cylinders.

Somebody here suggested you do just that, turn your tubes into hydraulic cylinders. With very little load on them you should be able to do that with simple "O" rings, cups like the type that go in automobile brake cylinders, etc.

Except for the fact that you wanted this to be manual, no power, my first thought was something else that looks like, and acts like, a hydraulic cylinder, i.e., a linear motor.

Seems you solved your problem in the stating of it and may not be able to see that for the trees.

Simply put, and your lawn motor handle simile was very clear, you want something like that that can be actuated with hydraulics. Think about it. You have really solved your own problem.

Using the tubes is a good suggestion. The lower tube would be the body of the cylinder; the top tube would fit inside it and be the rod. Add seals, and Bob's your uncle.
