Abstract
Abstract A device for controlling the flow of a fluid material as it is presented to a screen of a conventional material separator to isolate any solids carried therein consists generally of an adjustable baffle plate within a conical hood member. The input fluid is directed against the baffle plate and is thereby deflected against the hook member which is suspended over the screen. The fluid then follows along the hood member and falls to the screen, being presented thereto as an annular sheet of fluid material. The precise configuration of the sheet of fluid material is controlled by adjusting the axial location of the baffle plate, moving it toward and away from the direction of the flow of the input material. The solids which are unable to pass through the screen are transmitted to a discharge chute located at the periphery of the screen.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
169 words
Apparatus for controlling the flow of fluid material to the screen of a material separator or the like comprising a conical hood means for deflecting the fluid material directly toward the screen angularly away from the center thereof, said hood means being suspended above the screen and having both axial ends thereof open, transverse plate means suspended within and spaced from said hood means, said plate means having a diameter larger than the smaller end of said hood means and having a diameter smaller than the larger end of said hood means, means to adjust the axial position of said plate means, and means affixed to the smaller lend of said hood means and supporting said hood means to present the fluid material through the smaller end of said hood means and against said plate means so that the fluid material is deflected therefrom toward said hood means, the larger end of said hood means being proximate the screen and spaced inwardly of the outer periphery of the screen.
Claim 2
Dependent Claim
169 words
Apparatus for controlling the flow of fluid material to the screen of a material separator or the like comprising a conical hood means for deflecting the fluid material directly toward the screen angularly away from the center thereof, said hood means being suspended above the screen and having both axial ends thereof open, transverse plate means suspended within and spaced from said hood means, said plate means having a diameter larger than the smaller end of said hood means and having a diameter smaller than the larger end of said hood means, means to adjust the axial position of said plate means, and means affixed to the smaller lend of said hood means and supporting said hood means to present the fluid material through the smaller end of said hood means and against said plate means so that the fluid material is deflected therefrom toward said hood means, the larger end of said hood means being proximate the screen and spaced inwardly of the outer periphery of the screen.
Claim 3
Dependent Claim
169 words
Apparatus for controlling the flow of fluid material to the screen of a material separator or the like comprising a conical hood means for deflecting the fluid material directly toward the screen angularly away from the center thereof, said hood means being suspended above the screen and having both axial ends thereof open, transverse plate means suspended within and spaced from said hood means, said plate means having a diameter larger than the smaller end of said hood means and having a diameter smaller than the larger end of said hood means, means to adjust the axial position of said plate means, and means affixed to the smaller lend of said hood means and supporting said hood means to present the fluid material through the smaller end of said hood means and against said plate means so that the fluid material is deflected therefrom toward said hood means, the larger end of said hood means being proximate the screen and spaced inwardly of the outer periphery of the screen.
Claim 4
Dependent Claim
169 words
Apparatus for controlling the flow of fluid material to the screen of a material separator or the like comprising a conical hood means for deflecting the fluid material directly toward the screen angularly away from the center thereof, said hood means being suspended above the screen and having both axial ends thereof open, transverse plate means suspended within and spaced from said hood means, said plate means having a diameter larger than the smaller end of said hood means and having a diameter smaller than the larger end of said hood means, means to adjust the axial position of said plate means, and means affixed to the smaller lend of said hood means and supporting said hood means to present the fluid material through the smaller end of said hood means and against said plate means so that the fluid material is deflected therefrom toward said hood means, the larger end of said hood means being proximate the screen and spaced inwardly of the outer periphery of the screen.
Claim 5
Dependent Claim
11 words
Apparatus according to claim 1 wherein said plate means is circular.
Claim 6
Dependent Claim
16 words
Apparatus according to claim 1 wherein said means to present the liquid material includes piping means.
Claim 7
Dependent Claim
40 words
Apparatus according to claim 1 wherein said means to adjust the axial position of said plate means includes a threaded rod attached at one end to said plate means so that rotation thereof selectively raises and lowers said plate means.
