Abstract
719,823. Pruning tools. BARTLETT, W. F. Feb. 26, 1953 [May 8, 1952], No. 11668/52. Class 6 (2). [Also in Group XXII] A pruning tool comprises a pistol handgrip receiving the rear end of a tube and of a rod slidable within the tube, the rear end of the rod having driving connection with a trigger associated with the handgrip and the tube being apertured near one end to receive the stem which is cut by the front end of the rod in co-operation with an edge of the aperture. As shown, one end of a tube 3 is a sliding fit in a sleeve part 2 of a hollow handle 1a of wood or plastic, the other end of the tube having a slot 4 receiving the stem which is cut by the chamfered edge 6 of a rod S when a pivoted trigger 8, having a notch 8a engaging a down-turned portion 7 of the rod, is operated by hand pressure against the action of a spring 12. Any shortening of the rod resulting from resharpening of the edge 6 is compensated for by loosening the nut 15 and drawing the tube 3 along the sleeve 2 by the adjusting screw 17, In a modification, the tube is bowed or bent and the rod is replaced by a wire guided by rings fixed to the wire and movable in the tube. In a further modification, a coi'ed compression spring disposed at the rear of the rod restores the movable parts to their initial positions.
