Devices for Converting Motion, of which the following is a full, clear, and exact description. Reference is to be had to the drawings, forming a part of the patent specification. System can convert motion wave (or reciprocating rectilinear) power and transport energy of surface waves, and the utilize that energy to do useful work — for example, electricity generation. Machinery exploiting rotary motion power is known as a wave energy converter (WEC).



The object of this device is to provide mechanical movements for converting reciprocating rectilinear motion into continuous rotary motion, by the use of which more power can be obtained with the same length of stroke, and the dead-centers can be more easily and smoothly passed than when a crank is used in the ordinary manner. The invention consists in the construction and combination of various parts of the mechanical movement, as will be hereinafter fully described and then claimed.

A represents the frame of the movement in bearings in which a shaft revolves. To the shaft an eccentric is secured, which revolves within the eye of the strap. The lower end of the strap is pivot-ally connected to a reciprocating cross-head which slides in ways on the frame. The crosshead is reciprocated by means of the piston-rod, working in the steam-cylinder (or wave buoy). It will be seen, therefore, that the reciprocating move-ment of the cross-head will cause the strap to continuously rotate the eccentric and the shaft to which the same is secured.

The combination, with the cross-head, ways, and shaft, having attached eccentric, of the connecting eccentric-strap, pivoted to said cross-head, substantially as herein shown and described, whereby a reciprocating rectilinear movement applied to the said cross-head will give a continuous rotary movement to the said shaft, as set forth.
