Measures to secure a patent for improvements in the above have been taken by P. G, Gardiner, of New York City. By this improvement the horse-power can be readily adjusted to drive any machinery, although it should be fixed in such a position as to render the ordinary arrangements useless. By causing to be adjustable the belt pulley, which transmits the force from the motive power to the machinery, the above-mentioned difficulty is surmounted, for the pulley can be turned and brought in line with the driving pulley of any machine, however inconveniently the latter may be situated. The plan adopted is briefly this, the shaft which carries the adjustable pulley rests in bearings fixed to a collar, which moves loosely around a socket, butreaa-be held fast in any desired position by set screws.
