摘要： A portable horizontal drill press for drilling holes in the surfaces of highway vehicles and construction type equipment including a T-shaped base support beam which is mounted on swivel type wheels with low clearance provided to minimize tipping. A drill support column having a slidable mounting platform for an industrial type drill motor is mounted at one end of the beam support structure. The drill motor platform includes a hand wheel and lead screw combination which is used for feeding the drill motor into the work. The height of the drill motor platform can be adjusted either by a rack and pinion gear provided on a one-piece solid column or the column can be provided in several telescoping sections which can also combine a rack and pinion gear for the upper section of the column. A similar height elevating and positioning arrangement can be provided for a center support column provided at the opposite end of the base support beam. The center support column can be longitudinally moved with respect to the drill platform along the elongated support beam for adjusting the position of the drill center column in relation to the drill motor. A drill center rod is provided on the center support column and adjusted to contact that opposite side of the object so as to back-up the drill during the drilling process. In one embodiment the drill support column has a pivoting socket arrangement whereby the column can be laid down parallel to the support beam to allow the center column to be moved under an object having low clearance and then erected for positioning the drill center opposite the location of the area to be drilled.
摘要翻译： 一种用于在高速公路车辆表面上钻孔的便携式水平钻床和包括T形基座支撑梁的建筑类型设备，其安装在提供低间隙的旋转式车轮上以最小化倾翻。 具有用于工业型钻机电机的可滑动安装平台的钻头支撑柱安装在梁支撑结构的一端。 钻机电机平台包括手轮和导螺杆组合，用于将钻机电机进给到工件中。 钻机电机平台的高度可以通过设置在单件固体立柱上的齿条和小齿轮进行调节，或者柱可以设置在几个伸缩部分中，这些伸缩部分也可以组合用于上部的齿条和小齿轮 柱。 可以为设置在基部支撑梁的相对端的中心支撑柱提供类似的高度提升和定位布置。 中心支撑柱可以沿着细长支撑梁相对于钻台平行地纵向运动，用于调节钻中心柱相对于钻机电动机的位置。 钻中心杆设置在中心支撑柱上，并被调节以接触物体的相对侧，以便在钻孔过程中备用钻头。 在一个实施例中，钻头支撑柱具有枢转插座布置，由此柱可以平行于支撑梁布置，以允许中心柱在具有低间隙的物体下移动，然后竖立以将钻头定位在与 要钻的地区。

摘要： A quick coupling apparatus is provided for interchanging any number of vehicle body units on a single vehicle chassis when each of the body units and the chassis has a pair of parallel longitudinal standardly spaced beams whereby the beams of the body unit will overlie and be supported by the chassis beams when the components are coupled. The coupling apparatus has a plurality of hook-type tabs spacedly positioned on the sides of the body beams and a corresponding number of coupling brackets mounted on the sides of the chassis beams. Each of the coupling brackets being capable of receiving a tab and securing the body unit to the chassis when the body is moved slightly in a longitudinal coupling direction. At least one of the coupling brackets having an enclosing outer plate which forms a retaining slot which can receive a wedge behind the tab for locking the tab and body in position with respect to the chassis. The wedge includes an additional latch device for releasably retaining the wedge in locking position during use of the coupled body unit. The mating angles of the tab and bracket contacting surfaces and the wedge and bracket contacting surfaces have been found to be important to the proper operation of the assembly.
