For centuries the inventions of automated crankshaft, camshaft, reciprocating double-action piston suction hydraulic pump with suction pipes, overshot curvaceous water turbines, and
crank-connecting rod mechanism have been credited to Leonardo da Vinci (1452 – 1519) and Lester Allan Pelton (1829 – 1908). Recently,
the concepts of these proven significant inventions in fluid mechanics
and energy conversion systems have been found mentioned in the
manuscripts of an inventor whose name is Abu-Aliz Al-Jazari
(1136-1206). Leonardo da Vinci got these ideas from Al-Jazari’s
manuscripts and did not acknowledge Al-Jazari in his relevant
manuscripts. In Lester Allan Pelton receives the credit for inventing
the over-shot curvaceous water turbine whereas the over-shot
curvaceous water turbine was described in Al-Jazari’s manuscript
which was made publicly available for reading many centuries
before the time of Lester Allan Pelton. The concepts of these
inventions which are described in Al-Jazari’s manuscripts proves
that his manuscripts were among the sources from which Leonardo
da Vinci got these ideas and that Al-Jazari invented the over-shot
curvaceous water turbine many centuries before Lester Allan Pelton
are presented in this paper. It has been virtually proved that the true
inventor of automated crankshaft, camshaft, reciprocating double-action piston suction hydraulic pump with suction pipes, overshot curvaceous water turbines, and crank-connecting rod
mechanism is Abu-Aliz Al-Jazari.
