Abstract

This is an apparatus to facilitate securing radiator tanks onto header plates of automotive radiators and the like of a type made either from brass or of plastic having a gasket trough and integral header tabs. It includes opposed rails suspended from an overhead support, preferably circular to afford 360.degree. rotation, and arranged for individual movement towards and away from each other in substantially parallel relationship to support the header on different thicknesses of radiators for mounting the tank thereon. In one position, opposed edges of the rails are notched to hold radiators of varying sizes and types with easy access to header tabs on plastic radiators and in an inverted position, the rails are provided with a flange to support the underside of the gasket trough on plastic tanks with good access to the tabs. Opposed parallel channeled beams supported above the rails are designed to slidably receive and release any selective number of manually operated acme threaded screw clamps with a balanced crank handle on top and an adjustable V-shaped radiator tank engaging clamping pad on the bottom. Each clamp tilts laterally away from the tank on either side into selective detent held positions to provide access to the tank. Each screw clamp is provided with pressure calibrated spring means and pressure indicating indicia to obtain uniform pressure on the tank. This apparatus permits use of conventional tab tools and weighs approximately fifty pounds so it can be conveniently stored when not in use or transported to any desired location.
