摘要： The hydraulic jack has a pole gripping attachment with a swivel chain attachment means operable in a slot therein to provide for chain tightening with minimum piston movement and little or no eccentric loading of the piston. The cylinder is of single acting design with dual tandem spring return. High hydraulic pressure (over 6,000 PSI) is used to facilitate light weight and compact design features.

摘要： An extensible trailer tongue is telescoped beneath the floor of the trailer with a hitch on its forward end at an appropriate level for attachment to a vehicle ahead, and when extended forwardly the tongue is raised to a higher level and locked in position to clear road obstacles, with the hitch lowered relative to the tongue to again be disposed at the appropriate level for attachment to the same vehicle ahead. The tongue rides loosely between an upper and a lower track facing each other, and has upper rollers at its rear end bearing upwardly against the upper track and lower rollers disposed forwardly of said upper rollers and supporting the rear end of the tongue on the lower tracks. Means are provided to take up the looseness between the tongue and the track at hitch locations of the tongue. The body of the trailer has a platform for supporting utility poles and equipment with adjustably positioned stakes at either end and with a triangular central pillow serving as a central stake to position logs to one side of the trailer body. Side stakes or pole bolsters are secured in selected positions by lateral pins on one side thereof entering corresponding key slots in the side walls of the trailer with heads on the pins interlocking the stakes against displacement and with spring loaded lock bolts preventing raising of the pins out of their corresponding slots. The platform is reinforced longitudinally by upstanding cabinets along either side, by a longitudinal channel extending centrally beneath the platform and receiving the tongue, and by diagonal compartments on either side of the channel. Cross beams are provided at the ends and beneath the platform.
摘要翻译：一个可伸缩的拖车舌头可伸缩在拖车地板的下方，其前端有一个适当的水平位置，用于连接到前方的车辆，当向前延伸时，舌头被升高到较高的水平并锁定在适当的位置以清除道路障碍物，相对于舌头降低的钩子再次被设置在适当的水平以附接到前面的同一车辆。舌头松动地在彼此面对的上下轨道之间滑动，并且在其后端具有向上抵靠上轨道的上辊和设置在所述上辊前面的下辊，并且在下轨道上支撑舌头的后端。提供手段来承担舌头和舌头之间的牵引位置上的轨迹之间的松动。拖车的主体具有一个平台，用于支撑两端可调节定位桩的电杆和设备，并具有用作中心桩的三角形中心枕头，以将原木定位在拖车主体的一侧。侧桩或撑杆通过其一侧上的侧销固定在选定位置，其进入拖车侧壁中的相应的键槽，销上的头部将桩脚互相抵抗位移，并且具有弹簧加载的锁定螺栓，防止销钉升高的相应插槽。平台通过沿着任一侧的竖立的纵向通道，通过在平台下方中心延伸并且接收舌头的纵向通道以及通道两侧的对角隔间来纵向加强。横梁设置在平台的两端和下方。

摘要： A plurality of spaced keyhole slots facing in the same direction are provided in one member, and the other member to be attached thereto is provided with correspondingly spaced and positioned headed projections adapted to be received through the larger portion of the slots and to interlock with said first member upon relative shifting between the members in a direction moving the headed projections into the smaller portions of the slots. A spring biased interlock retains the members against dislodgement of the projections from the slots until released.
