<p>The present invention relates to an operating means for moving a feed apparatus of elongated pieces of timber, particularly logs, into a transversal feed apparatus, for moving reciprocatingly the feed apparatus, said feed apparatus being arranged to feed pieces of timber piece by piece from a reception point (7) to a discharge point (8) and said feed apparatus having a step-like configuration and said feed apparatus comprising a reception step member (1), which is movable reciprocatingly between the initial position thereof, in which the upper surface part (9) of the reception step member is substantially on the level of said reception point (7), and the discharge position, and a discharge step member (4), which is movable back and forth between the discharge position thereof, in which the upper surface part (15) of the discharge step member is substantially on the level of said discharge point, and the reception position thereof, and possibly one or more additional step members (2, 3). Said feed apparatus have been used in prior art in hydraulic cylinders, crank mechanisms and connecting chains used in a reciprocating electromotor. Said designs have been complicated, slow and require plenty of power. As taught by the invention, the feed apparatus is used in an operating means (17) comprising a crank means (18, 19, 20) operating the step members (1, 2, 3, 4).</p> |
