Patent XC-193: 1844-05-30, Mode by which power, to be derived from the use of the wheel and screw, may be applied to any kind of machinery

XC patents are Canadian patents issued between 1824 and 1869. “This power may be applied to almost any kind of machinery in mills or manufactories, in place of gearing and straps; the advantages of which are, a steady motion and avoidance of vibration or check, a great velocity acquired from the first mover, whereby less space is occupied and intermediate gearing prevented. The motion may be reversed without change of position of wheels or shafts, and any angle of shafting may be taken, or a horizontal shaft may be taken either from a horizontal or vertical wheel.”
