Patent number: 5732827Abstract: The invention is a screening apparatus for classifying material of different sizes. A screen is rotatably mounted on a frame for rotation around a first axis which is angled upwardly away from the horizontal, at an angle of from 0 to 30 degrees. The screen is symmetrical about the axis and has an open upper inlet end and a lower outlet end. The screen has a cylindrical portion extending from the inlet end towards the outlet end, having a diameter larger than its length, and a conical portion extending from the cylindrical portion towards the outlet end, tapering inwardly to a central outlet opening, the lowest point of the outlet opening being substantially higher than the lowest point of the screen. The frame is pivotally mounted on a trailer for pivoting about a longitudinal axis near a lower side edge of the trailer. The open inlet end of the screen faces one side of the trailer.Type: GrantFiled: October 25, 1995Date of Patent: March 31, 1998Assignee: Portec Inc.Inventor: John P. Dorscht

Patent number: 5641037Abstract: The invention is a wiping bar of a rail lubrication apparatus of the type used with a rail having a base with outwardly extending flanges, a head, and a web connecting the base and the head, where the lubrication apparatus is comprised of a wiping bar and a first set of clamps for maintaining the wiping bar in position with respect to the rail. The lubrication apparatus also comprises a pump actuator and a second set of clamps for maintaining the pump actuator in position with the rail. The rail lubrication apparatus may be used with a pump, responsive to the pump actuator, for pumping a lubricant from a reservoir to the wiping bar to form a complete rail lubrication system. Specifically, the wiping bar of the present invention includes an improved distribution blade over those known in the art. Further, the wiping bar of the present invention includes the improvement of coating the surface of the wiping bar contacting the lubricant with an anti-stick material.Type: GrantFiled: June 6, 1995Date of Patent: June 24, 1997Assignee: Portec, Inc., R M P DivisionInventors: Bruce R.

Patent number: 5518085Abstract: An assembly for applying a solid material, such as a lubricant or an anti-slip material, to wheels. The system includes a pair of spring actuated members located on opposite ends of a holder for the solid material to urge the holder upwardly along guide pins to force the solid material to contact a wheel as it passes over a rail and the solid material element. The solid material element is held or "pinched" between the wheel flange and the gage face of the rail, thereby applying the material to the wheel which, in turn, transfers the material to the rail surface. The upward motion of the solid material is counteracted by a braking arrangement, including a brake release, so that a wheel passing over the release, releases the braking arrangement to allow the solid material to move upwardly to contact a wheel.Type: GrantFiled: February 21, 1995Date of Patent: May 21, 1996Assignee: Portec - RMP DivisionInventors: Howard M. Houser, Jr., Bruce R. Wise, William T. Urmson, Jr.

Patent number: 5484111Abstract: The hammers provide multiple impact points for debris, by providing impact points via tips at different radii from the axis of rotation of the hammer mill. The tips preferably are at substantially the same radius from the axis of rotation of the hammer about the hammer support shaft, so that efficiency is maintained even as the hammers lay back. The multiple impact points produce a more effective result, by partially sizing the debris on initial impact, before more precise final sizing in the grinding chamber. Angled surfaces on the hammer tips provide more effective shearing and tearing action than with conventional bar hammers. Wear patterns are such that grinding efficiency as the hammers wear down is maintained throughout the life of the replaceable tips. Preferably, the hammers weigh substantially more than conventional hammers, to provide a higher energy impact, and to reduce the tendency of the hammers to lay back.Type: GrantFiled: May 31, 1994Date of Patent: January 16, 1996Assignee: Portec Inc.Inventors: John P. Dorscht, Patrick J. Hogan
