A simplified MT 13 ...

[iacob alex]

    Hi Jim!
As I see the things,after visiting Bessler's 143 designs,I was interested about MT13.

Why? Simply,because it was in the same line of an old solution(Villard,Taccola,da Vinci and others).

With MT13,he used the "classical" short arm-long arm reasoning,as simple as possible:

  -in the lowest point,the long arm becomes a hinged arm(short arm),so easy, in the most natuaral manner ,due to gravity.

  -in the top position,the same hinged arm,needs some "help",to switch  back into the long arm...here we have a problem,in fact the only one ...

  This "help",can be acquired from a stored rotational inertia,as an effect of gravity fall.

  Bessler's improvement was to minimize the switching time/and space from 180*(Villard,Taccola...) to 90*.

  "A simplified MT13..."(two spokes only) can reduce even more this switching time,from 90* to a smaller value...

      All the best! / Alex

    ...or Bessler's MT13, can be a starting point to achieve a PM,if we imagine and test,two steps :

           -to simplify(two opposite arms,only).
           -to modify (one hinged arm,only).

       Some details,you can find at /Gravity "wheel" concept/.

                All the best! / Alex

    Hi !

A simplified MT 13 , as a new test , is the same arrangement but with two opposite arms ,only ...in this manner playing a prolonged gravity unbalance .

.....if we take into consideration the redundancy of MT 13 design , at :

     The test , at : https://youtu.be/SA7noI8sHL8
     If we minimize the number of the spokes/arms to a pair of  two opposing , only ...we can open the "gate" for a new simplified experience , as:

     The "wheel" becomes a simple lever ( age )...
