Patent ID: 7780013

Claim:
A fire department connection with debris filter comprising: at least one pipe fitting; at least one upper pipe that is a pipe or a tube; a downward flow debris filter; and a lower pipe that is a pipe or a tube, wherein, said at least one pipe fitting: functions to fluidly connect to another pipe fitting on a fire hose, is located at the upper frontward portion of said fire department connection with debris filter, and is fluidly coupled to said at least one upper pipe, said at least one upper pipe is fluidly connected at one end to said at least one pipe fitting and at its other end to said downward flow debris filter, at an upper surface of said downward flow debris filter, said lower pipe is fluidly connected at its lower end to the fire protection system of the building and at its upper end to a bottom surface of said downward flow debris filter, and said downward flow debris filter is: rectangular prism-shaped on its front half and circular prism-shaped on its back half, where the diameter of the circular prism is essentially the same as the width of the rectangular prism to allow the sides of the rectangular prism to form a smooth seamless connection with the sides of the circular prism to yield a complete enclosure with a front surface, a rear surface, a set of two side surfaces, along with said upper surface and said bottom surface, wherein said smooth seamless connection reduces swirling turbulence and debris deposits in the upper portion of said downward flow debris filter, not positioned horizontally when installed, but rather the profile of said downward flow debris filter is angled at 20-70 degrees from horizontal, where the front of said downward flow debris filter is positioned below the back of said downward flow debris filter, and positioned so that fluid flows downward through said upper surface of downward flow debris filter, downward through said a downward flow debris filter, through said bottom surface of said downward flow debris filter, through said lower pipe, and on to the fire protection system of the building.
