Marquess of Worcester

[agor95]

Edward Somerset, 2nd Marquess of Worcester (9 March 1602 or 9 March 1603 – 3 April 1667)

There are times one stumbles into some information that feels there is 'gold here'.

I have created this topic on this subject for any long standing contributors to constructively evaluate the potential route present in this persons invention.

P.S. Lets bridge over the time of his day to Bessler and then onto our time.

Shame he is not here with us today and above topic stopped two years before I joined.

It is fair to say there is not much to go on from Marquis' day.

However Bessler did refer to having his head chopped off.
Charles I suffered that fate. However this gravity wheel was presented
in the tower to the King before that event.

It is speculation that Bessler found out about the Marquis' inventions on his visit to England.

[agor95]

I am studding this device's potential implementation.

So we know the dimension but no depth.
The number of weights 40 of size [50 pounds] and their movement from inner to outer.

Their displacement was 1 foot in a 14 foot diameter wheel.

We know there is so much belief in the way blocking the building of this wheel.

However let me draft what I expect and trust you will support me in this investigation.

The device self-starts and accelerates to it's operating rate of rotation.
If it were too rotate too quickly then the wheel would slow down automatically.

It is a gravity only device and the path of, in this case, cannon balls are relevant.

There is nothing else used not even knocking or swinging of masses.

The aim is to look for a design that is table top size using marbles.
A lot less than 40 and more than 1.

P.S. It is only fitting to use marbles for I have lost my bearings [Steal ball bearings]. I would like it not to have any magnetic components.

All the Best

The negatives :-

1. No masses within a rotating circular path can create positive torque.
2. Potential Energy due to height used has
to be return to get that height back.
3. Watch how many weights are on each side?
4. Levers function are a law of mechanics and can not be fudged.

Well those are the main blocks - I must me losing my marbles - hopefully.

[agor95]

The image below is a base structure of the study subject.

The original description was for 40 moving cannon balls.

Well I am keeping it simple as possible.

You are looking at a spoked wheel with a yellow axle.

The two blue items are temporary guides.

There are three small sectors. The top section of these holds one of three marbles.

As the wheel rotates counter clockwise the top marble can not go below this blue top guide until it reaches the outer position.

A marble can not go below the blue bottom guide while it is not at it's inner position.

The path of the marble is confined to each top section of the small sectors.

The test is to control each marble so at every angle of rotation the marbles are creating positive torque.

In the wheel position shown a marble needs to be in the inner position at 12 o'clock.

The marble on the left needs to be in the outer position in the middle at 8 o'clock.

The marble on the right needs be in the inner position in the middle at 4 o'clock.

So all is balanced except the 8 o'clock marble is over balancing the wheel.

As the wheel rotates the top and left swap from outer to inner position

So there is always an overbalanced left side situation.

Note. A machine made glass marble has standard shape and size.

All the Best - Who moved my marbles?

[Tarsier79]

The description of the Marquess' wheel makes no sense to me. Why would you want the weight to move further from the center after passing the diameter line of the lower side? Is the line horizontal or vertical? Also he uses the word 'hung'. So I suspect it is a simple corded OB wheel.

Just found an image that suggests the same in its title and added:

[Fletcher]

Here's a pic of the Marquis's wheel from the Ord-Hume book mentioned in earlier threads about this wheel.

It is an attempt to create a self-moving wheel, that LOOKS like it should have good possibilities for continued imbalance/overbalance.

In many ways this very simple and easy to follow illustration drives the message home, or should do !

That the girls were far prettier in Geography than the Sciences, and those were the classes I always attended lol.

[agor95]

Thanks all

At least Fletcher's offering has the 50 pound weights in a confining box.
With cords that are in use i.e. weights hanging.

I treat the anchor points as were the actual force is being applied.

When the weight is in contact I use that location.

I hope some one has tried a simple physical build & test.

Well the good news is; what I am currently looking at has no ropes.
So I can call it what ever I want.

And I have no idea were I viewed the image that set me off on the 1640 quest. It had a front and side view.

No matter lets see were it take me.

Ho raising the marbles is the easy part.

Lowering them and dealing with excess rotation rate needs a little management.

Agor, I have seen a version of your marble machine on YouTube. The marble falls through a hole in the back plate, runs along a marble run, popping through another hole back on to the wheel. I guess the wheel was angled back slightly. Sorry, cant find the video atm.

Also, here is where I did an early investigation into cams. The same principle applies. The forces are reasonably easy to calculate.

It all makes sense !!! :)

Hi Agor95,
hopefully you see that the Center of Mass is below the turning point, axle of the wheel.
So someone has build such a version already, you must only look around in some museum.

An other version of rolling a cylinder in a hole, but the complete mass is above the the turning point.

[agor95]

Hello Georg

It appears my marbles are rolling off in several directions.

I will have to watch I do not loose my marbles.

To address your images. Readers here should be aware the C.O.M. [Center of Mass] always tries to hang below the axle at the lowest point it can.

Your first image and last are equivalent as the individual hanging components follow the above rule and combine to create a net affect on the wheel. The last image has only one component and with rollers you get a version of the first image.

I am thinking about your Ideas and I will post them in your dedicated topic.

The second image shows you have to do work to raise up a C.O.M.

P.S. I have three lines of inquiry the above cord wheel.
The wheel I am presenting, which needs another name.
Another possible design is based on the 'Unnamed' put having
rod pendulums anchored like the cord but implemented like
Scott Hall's inspired design.

Hello thx

I was thinking how I could used a 3D printer without owning one.
Also how to distribute a 3D model to all that have a 2D printer.

So the idea is to print each slice of the model as an 'Edge Line Image' on A4 printing paper. Then cut them out and stick them together.

So we can all have a 3D printer.

There are improvements to this idea like special paper that self sticks using heat [warmth].

Perforations around each image so you do not have to cut them out.
Also many shape line images on each page to maximise each A4 page.

This would be used in A4 size Books were you read the text of the book on the odd numbered pages. On the other side of the page i.e. the even numbered pages would be the shapes.

That means you read the book. Rip out the pages along the full length spine perforations.
Then poke out the shapes within each page.

In effect you get your readers to destroy your books. Thus making them really rare and valuable.

However the first is software that helps convert a 3D model to 2D slices.
Then combine these 2D slices into a A4 size area for printing.

P.S. Students use to either offer themselves to the Hairdressing classes
Or enrol into the classes for the same reason as Fletchers quote.

Note. Ho bugger just type this '3D model to 2D slices' into a search engine.

I don't know how he really does it, but it's not bad. :)
