Well, I can imagine the future development of Feliks Crosshead:



So here is such a nice professional site with such an engine with a variable degree of compression ..
But the crank layout has modes ...

The lateral force of the piston has not been removed, only moved to the side wall ..

Yes, here is the engine, in this also the piston does not beat the cylinder .. But too complicated and I still do not like modes. And the lateral force of the plunger and so-called tobaccos somewhere is lost ...
But he will read for it, what it gives ... I do not have to tire about writing the advantages of my crosshead ..

And here is how something is not going on when crosshed ..




And now he will not ...

Nice video, and at the end you can see how fast it can turn,

So I continued to divide the hair into four...

Yes, we slowly develop this way of bypassing the lateral force of the piston .. here, that's all you have to do is one lever that has a half-ring at the end, but the other way round. This way one pulls up and the other down during the movement of the lever ... It can be used for a full four-stroke engine .. Well, see how easy we can cool the water piston ..

Does not this remind you of the mechanics drawn by James Watt ? But it's necessary to back 250 years back ..


Hand-drawn diagram by James Watt explaining his discovery of the "parallel motion" in a letter to his Sohn: "The idea originated in this manner. On finding double chains, or racks and sectors, very inconvenient for communicating the motion of the piston-rod to the angulat motion of the working-beam, I set to work to try if I could not contrieve some means of performing the same form motions turning upon centres, and after some time it occured to me that AB, CD, being two equal radii revolving on the centres B and C, and connected together by a rod AD, in moving through arches of certain length, the variations from straight line would be nearly equal and opposite, and that the point E would describe a line nearly straight, and that if for convenice the radius CD was only half of AB, by moving the point E nearer to D, the same would take place; and from this the construction, afterwards called the parallel motion was derived."

Of course, instead of a rope, you can use any type of parallel movement mechanism.

https://en.wikipedia.org/wiki/Parallel_motion

And of course, it's getting higher and higher speed after that ...

So this Wats is not bad anymore .. but this string can have such a form of springs from the watch's bannister .. and then it is the simplest solution and guaranteeing higher revolutions .. obviously the ideal is Peaucellier-Lipkin, but also is the most complicated .. But after some analysis, to which the arms attach to the connecting rod, i.e. which carries the main forces, the rest may not have to be a monstrous size ..
In any case, the use of a traditional crosshead certainly became archaism ... because with the use of any of these solutions, the side force on the crowd does not occur, and was not moved below, to crosshedas, and was liquidated at all ..

Also from my drawing you can see that a very easy way we can do cooling with the water of the piston ..
This can give us, due to its very low temperature, a change to Teflon efflorescence and one would be tempted to completely give up the oil.
And this is a very important matter, which allows us this construction, so it seems to me that maybe you can do practically this matter and try some teflon bearings and seals

Historical notes
Sylvester (Collected Works, Vol. 3, Paper 2) writes that when he showed a model to Kelvin, he “nursed it as if it had been his own child, and when a motion was made to relieve him of it, replied ‘No! I have not had nearly enough of it—it is the most beautiful thing I have ever seen in my life.’”








Which of these three mechanisms to use ... and here the magnitude of the lateral force on the piston in the C-spot ... as you can see on 1/3 of the torque it achieves .. THEREFULLY IT WILL NOT BE HERE ... :clap:

Which to use?
This is a good question ..
With a new construction a lot of unknowns ... here is one but also a new 3 ways to connect the connecting rod ..
And not only the mathematics of movement, but now all force must be determined ...
A lot of work for sure ..




I wonder where this side force acting in the crosshead has died?

Tak i tu dochodzimy do sedna sprawy , i widać ,że jest to sprawa polityczna..
ale to wynalazcy naprawdę rządzą Światem , a nie politycy ..

And nowadays, how to design an engine that will save 10% of fuel in the ship's engine, because there is no friction in its traditional crosschead, then here you can see and count how much it can be ...
