Life

The son of the doctor Pierre André Peaucellier and the pharmacist's daughter Catherine Bassigny had four siblings. He embarked on a military career. As a captain, he led a pioneer corps in Toul , was then field commander of Lyon and then, again in Toul, served as a grand officer and member of the general staff in an elite technical unit. In 1868 he married the 25-year-old Marie-Hélène Defrance from an important industrial family in Dillingen. She died in 1872, early in the year her daughter Jeanne was born; probably in childbed. In 1876 he married the 24-year-old Marie-Thérèse Sthème de Jubecourt from Wallerfangen . The marriage had two children. The older André Peauccellier was 37 years old and fell in the battle of Mèsnil-le-Hurrus in the First World War. The younger Felix Guy Marie Maxime, born in 1882, became an engineer. His mother probably died in childbed six days after he was born. In 1889 Peaucellier married Gabriele de Trévélec for the third time. When Peaucellier died, he was reburied in the Defrance crypt , the grave of his first wife, in Dillingen at the request of his children living in Paris . The public perception of the reburial was organized as a burial in the presence of a large mourners, representatives of the occupation corps and the Dillinger Hütte with military honors. In 1929 he was exhumed a second time and reburied with his first wife Marie-Hélène Defrance in Wallerfangen . The grave slabs for his first son, himself, his first wife and father bear the following inscriptions:

  • Ici repose André Peaucellier Capitaine au 5me Dragon tombé glorieux Mesnil-le-Hurrus le 28 Février 1915 à l'age de 37 ans
  • Ici repose Charles N. Peaucellier Général de Division Grand Officier à la Légion d'Honneur né à Sarrelouis le 16 Juin 1832 mort à Paris le 4th Oct. 1919

Strangely enough, on the tombstone of the Peaucellier family, the date of his son André's death is February 28, and January 28th on the tombstone of the Sthème de JUBECOURT family.

invention

He became known through the Peaucellier Inversor named after him , which he brought to the public in 1864.

Its construction consists of four rods of the same length, connected by joints to form a rhombus, which are guided by two longer rods attached to opposite joints at an external point.

This machine makes it possible to convert a movement on a (partial) circular line into a linear movement. In the lexicon of technology as a whole , the invention is recognized as follows:

“For a long time it was considered impossible that a straight-line movement could be produced by a hinge mechanism, in which each limb executes a circular motion against an adjacent one, until Peaucellier first invented the ... hinge mechanism through which an absolute Straight guidance is effected. "

Although ingenious in theory, the many joints and loads in them cause problems in practice.
