摘要： A cover assembly for the box of a pick-up truck. The cover assembly has a rigid cover that is sized to fit between the side walls of the box when in the closed position closing the open top of the box. The assembly includes support ledges fastened to the inside of the side walls of the box for supporting the cover in the closed position. The support ledges carry female pivots spaced from the side walls to form gaps. The cover carries male pivots that enter the gaps in the closed position of the cover, the male pivots in a non-cooperating position with the female pivots. When the cover is lifted from either side of the box, the male pivot on the opposite of the box moves to cooperate with the female pivot on that side to form a longitudinal pivot about which the cover swings when opened.
摘要翻译：一种用于拾取卡车箱的盖组件。盖组件具有刚性盖，其尺寸适于当处于关闭位置的情况下装配在箱的侧壁之间，从而封闭箱的开口顶部。组件包括紧固在箱体侧壁内侧的支撑壁架，用于将盖子支撑在关闭位置。支撑凸缘承载与侧壁间隔开的女性枢轴以形成间隙。盖子承载进入盖子关闭位置的间隙的阳性枢轴，阳性件与母体枢轴处于不协调的位置。当盖子从盒子的任一侧提起时，箱体的相反侧上的阳性枢轴移动以与该侧面上的阴轴枢起作用，以形成纵向枢轴，盖子打开时围绕该枢轴摆动。

摘要： A looper used in the manufacture of asphaltic roofing felt comprising a driven endless belt of spaced tubes adapted to carry loops of felt between adjacent tubes, a track inclined toward said loops, a trolley having fingers adapted to contact the foremost loop in the looper, rollably mounted on the track wherein the improvement comprises a chain driven at the same rate and in the same direction as said endless belt and means on said trolley to interlock with said chain actuated when said fingers have contacted the foremost loop whereby the trolley travels with the foremost loop and the fingers maintain a constant pressure or contact on the foremost loop, until the loop is pulled out of the reach of the fingers, whereby the fingers drop and deactuate the interlock means, allowing the trolley to roll by force of gravity until the fingers again contact the foremost loop and the operation is repeated.
摘要翻译：一种用于制造沥青屋顶毡的活套，包括适于在相邻管之间承载毛毡环的驱动环形带，相对于所述环之间倾斜的轨道，具有适于接触弯针中的最前回路的手指的手推车，可滚动地安装在轨道上，其中改进包括以与所述环形带相同的速率和相同的方向驱动的链条，并且在所述手推车上的装置与所述链条致动时互锁，当所述手指已经接触到最前面的环路时，手推车以最前面的方式行进并且手指在最重要的环路上保持恒定的压力或接触，直到环路被拉出手指的距离，由此手指将互锁装置放下并停用，允许手推车通过重力力滚动直到手指再次联系最重要的循环，重复操作。
