    摘要： A line clamp comprising a ring plate adapted to be secured in position on a mounting surface, e.g., a deck, or other platform, or the like, by means of headed screws, and with a sleeve mounted in the center thereof and projecting downwardly therefrom with a bore extending into and through the supporting surface. A shank mounted for axial movement in this sleeve has a dished upwardly convex clamp plate on its upper end, and a spring draws the shank downward to releasably clamp a line between the dished head and the mounting ring.

    摘要： Basic unit includes first variable length column and second preferably fixed-length column pivoted together at upper ends, with load contact member at the top of one column. Bases on each column maintain the unit in upright plane. Bases pushed toward each other to initially engage load. Variable length chain holds bases at desired spacing. At least one base frictionally engages ground to prevent undesired movement. First column is extended to swing second column toward vertical and raise load. To lift airplane struts located below load contact member, cable unit is attached to load contact member and extends down to strut to lift in tension. Two basic units are connected in laterally spaced relation for two-point lifting. Third support arm may be added to provide for three-point parallelogram-type lifting of entire airplane.

    摘要翻译： 基本单元包括第一可变长度列和第二优选固定长度列，其在上端枢转在一起，负载接触构件位于一列的顶部。 每列的基座将本机维持在直立的平面上。 底座相互推动以初始加载。 可变长度链以所需的间距保持基座。 至少一个基座摩擦接合地面以防止不期望的运动。 第一列延伸到垂直摆动第二列并提高负载。 为了提升位于负载接触构件下方的飞机支柱，电缆单元连接到负载接触构件，并向下延伸到支柱以提升张力。 两个基本单元以横向间隔的关系连接，用于两点提升。 可以添加第三支撑臂以提供整个飞机的三点平行四边形提升。
