发明名称 POSTS, BATTENS AND ACCESSORIES THEREFOR
摘要 A post and batten for fencing and other purposes which is provided with an opening in one face to facilitate locking engagement of a fastener thereto. Also described a hand post driver to cushion shock during use. A standard drive comprises a post tube, cross-bars and handles, these elements forming a rigid frame. The present invention modifies this arrangement by mounting a cap to the handles and interposing coil springs between the upper cross-bar and the cap. A solid plug is fixed in the end of post tube. There is no connection between the end of the tube adjacent the cap and the handles are free to slide in top-cross-bar. When the tube is impacted on a post the post exerts pressure on the plug and simultaneously the springs are extended cushioning the blow and then almost instantaneously the end of the tube is impacted by the cap providing supplementary downward force.
