Abstract
Abstract This invention relates to a trap for removing solid particles from a liquid flowing in a conduit. The trap comprises a filter element disposed across the conduit at an angle sloping rearwardly with respect to the direction of liquid flow in the conduit. A receptacle communicates with the conduit rearwardly adjacent to the lower end of the filter element.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
148 words
A flexible water hose having a horizontal leg and a vertical downwardly extending leg, said hose being adapted for coupling between a water-cooled engine block and its radiator, the opposite ends of the horizontal leg being clampingly connectable between the top of the radiator and the top water outlet of the engine block; a screen element disposed across the horizontal leg opposite the mouth of the vertical leg and at an angle sloping rearwardly with respect to the direction of liquid flow in the horizontal leg, whereby solid particles contained in the liquid which are larger than the openings in the screen will be reflected from the screen downwardly into the vertical leg, and a magnet positioned at the bottom of said vertical leg for attracting ferrous particles contained in the circulating liquid thereby preventing the ferrous particles from returning to the engine block when liquid circulation stops.
Claim 2
Dependent Claim
