Title: Automotive cooling system filter assembly

Abstract: A filter assembly capable of being removably disposed in a resilient hose adjacent a cooling liquid inlet to an automotive radiator for removing foreign particle material entrained with the cooling liquid as the latter circulates, and by such removal permitting the liquid to perform its intended function at maximum efficiency. The assembly includes a generally cylindrical rigid member that serves a two-fold purpose, namely, that of providing a support for a cone-shaped resilient screen, and also as a support for a V-shaped handle. The handle permits inserting of the assembly in a hose and removal therefrom without appreciable stressing of the screen. Stressing of the screen is highly undesirable, as it may result in permanent damage being done thereto.
