    • An apparatus for removing sealants from expansion joints in pavement slabs preparatory to replacement of the sealant is adapted for demountable attachment to the rear of a motorized vehicle. The apparatus includes a frame which is pivotably movable about a horizontal axis by means of a linear actuator. A carriage, having a cutting tool bit carried in a tool holder at the trailing edge thereof, is supported on the frame so as to be pivotably movable therewith with such movement employed for positioning and holding the cutting tool in the joint being cleaned. The carriage is free to laterally slide relative to the frame for freely tracking the expansion joint being cleaned.
    • 用于从准备更换密封剂的路面板中的膨胀节中去除密封剂的装置适用于可拆卸地附接到机动车辆的后部。 该装置包括一个可通过线性致动器围绕水平轴线枢转运动的框架。 具有在其后缘的工具架中承载的切削工具钻头的托架被支撑在框架上,以便与其一起可枢转地移动,这样的运动用于将切割工具定位和保持在待清洁的关节中。 托架相对于框架自由地横向滑动,用于自由跟踪要清洁的膨胀节。

    • A lightweight safe having an unique door mechanism is disclosed. The lightweight safe has a front opening with a recessed door frame to accommodate a recessed door having dead-bolts which are positioned behind one edge of the door frame when the door is in a closed position and movable locking bolts which may be locked behind an opposed edge of the door frame when the door is in a locked condition. The opening mechanism involves the use of a locking shaft having a pair of roll pins which interact with a handle lever to provide a smooth acting opening mechanism and to provide shear means in the event the handle of the safe is forced when the safe is in a locked condition.
    • 公开了一种具有独特的门机构的轻型保险箱。 该轻质保险箱具有一个前开口,带有一个凹入的门框架,以容纳一个具有止动螺栓的凹入门,当门处于关闭位置时,它们位于门框的一个边缘的后面,并且可锁定螺栓 当门处于锁定状态时门框的边缘。 打开机构涉及使用具有一对辊销的锁定轴,所述一对辊销与手柄杆相互作用以提供平滑作用的开启机构,并且在保险箱处于安全保护装置时被迫使用时提供剪切装置 锁定状态。

    • A machine for opening the joints and random cracks in pavement preparatory to placement of a filler-sealer material therein. The machine includes an open carriage having an opposed pair of side wheels and a shroud mounted in the carriage intermediate the side wheels. A cutter wheel is journaled in the shroud for rotation about a horizontal axis, and the cutter wheel is driven by an engine mounted atop the shroud. The shroud is pivotably coupled to the carriage for raising and lowering of the cutter wheel by moving the axis of the cutter wheel in an arc which passes through the axis of the carriage wheels.
    • 用于打开接缝的机器和路面中的随机裂缝,准备在其中放置填料密封剂材料。 该机器包括具有相对的一对侧轮的敞开的托架和安装在托架中的侧罩的护罩。 切割轮被挂在护罩中以围绕水平轴线旋转,并且切割轮由安装在护罩顶部的发动机驱动。 通过使切割轮的轴线以穿过托架轮的轴线的弧线移动,护罩可枢转地联接到托架上,用于升高和降低切割轮。
