Abstract: 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.

Abstract: 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.
