No. 23453.—7th September, 1907.—CHARLES SUTTIE, of Waharoa, Flaxmiller, and MONTAGUE HARRISON WYNYARD, of Auckland, New Zealand, Solicitor. A new or improved means of operating a mechanical catcher for flax and the like.*

Claims.—(1.) An apparatus for operating a mechanical flax-catcher combining a contrivance which when brought into gear with a driven wheel or pulley will operate a device designed to move the mechanical catcher at the required time after being operated and in the required manner, a driven wheel or pulley, means by which the contrivance is prior to flax being fed into the stripper kept out of gear from the driven wheel or pulley, means whereby the operation of feeding flax into the stripper brings the contrivance into gear with the driven wheel or pulley and thereby operates the contrivance, and means whereby the contrivance is thrown out of gear from the driven wheel or pulley after the mechanical catcher has completed its movement, substantially as and for the purposes described. (2.) An apparatus for operating a mechanical flax-catcher, comprising a rod or bar to which pressure by the person feeding flax into the stripper can be applied, and, acting directly or through leverage on a wheel-crank slide or other equivalent and appropriate gearing, gives the necessary movement to the mechanical catcher, with a tension to reverse the motion when the pressure is released, substantially as and for the purposes described.
