Talk:Chebyshev lambda linkage

2007
Does the animation really depict the Chebyshev linkage? Many sites refer to it as a 'Hoeken' or 'Hoekens' linkage. And some sites show a Chebyshev linkage as something different. Eg: http://www.softintegration.com/chhtml/toolkit/mechanism/fourbar/fourbarChebyshev.html ?Preceding unsigned comment added by 202.45.98.85 (talk ? contribs)
 * Yes, something isn’t right here. Found this quote on Cornell university website (with again another version) "Chebyshev spent several decades trying to find a theorem that would establish whether a linkage mechanism could draw an exact straight line". I think he invented multiple mechanisms and therefore is attributed to multiple. Here is the version you pointed out. This needs to be addressed, will dig into it. --Van helsing 10:58, 4 August 2007 (UTC)
 * And you’re absolutely right on the Hoeken(s) naming. Googling for “Hoekens linkage” often gives this article's mechanism. I’m just not sure if Hoeken(s) refers to the name of an inventor (Mr. Hoekens or "Hoeken's" linkage) or for example Dutch for corners/angles (linkage). --Van helsing 12:25, 4 August 2007 (UTC)
 * the book "how round is your circle" says it's an alternative form of the chebyshev as it generated the same curve SvenPB (talk) 23:52, 25 July 2008 (UTC)
 * Correct. I have added the note that the Hoekens linkage is actually a cognate of the Chebyshev linkage. ?Preceding unsigned comment added by 75.72.49.230 (talk) 22:45, 28 November 2009 (UTC)
 * In the kinematics research fields, this mechanism is introduced as "Hoecken's Mechanism" . - Assemblykinematics (talk) 13:20, 6 January 2014 (UTC)

Moved
Moved the article from "Chebyshev" to "Hoekens" linkage as this seems to be the prevailing name. Other names found are Hoeken-type, Hoeken, Hoeken’s and even Hoken linkage. --Van helsing 09:13, 8 August 2007 (UTC)
 * "Hoekens" and "Hoeken" are incorrect! This mechanism was developed by Karl Hoecken . . - Assemblykinematics (talk) 13:20, 6 January 2014 (UTC)


 * Hoecken was Born 1874, the plantigrade machine was shown 1878.
 * So "developed by Karl Hoecken" can not be the full truth.
 * But sure: It is named after him.

When invented and published
When was this linkage invented or first published ? - Rod57 (talk) 11:26, 7 September 2012 (UTC)
 * K. Hoecken: Steigerung der Wirtschaftlichkeit durch zweckmasige Anwendung der Getriebelehre. Werkstattstechnik, (1926), S. 209/17. - Assemblykinematics (talk) 13:20, 6 January 2014 (UTC)
 * The linkage was first shown by Chebyshev in Paris on the Exposition Universelle (1878) as "The Plantigrade Machine". The mechanism ist also known as Chebyshev's Lambda Mechanism--77.8.1.240 (talk) 15:02, 17 November 2014 (UTC)

What uses when
What devices has this linkage actually been used in ? - Rod57 (talk) 11:39, 7 September 2012 (UTC)
 * This type linkage were using for walking machines and walking robots . - Assemblykinematics (talk) 13:20, 6 January 2014 (UTC)

Someone renamed the article but not the talk page.
Why is talk page a link to the CLM? Someone screwed up when they renamed this. Paul Beardsell (talk) 17:38, 19 February 2015 (UTC)
