Patent number: 6152279Abstract: A safety barrier is provided for transports such as moving walks or stairs (escalators) which have a moving surface and fixed sidewalls. The barrier is a strip barrier brush assembly adapted to be attached to the sidewall and includes at least one brush strip adapted to project over the edge of the moving surface. The assembly includes a rail housing having a channel slot extending parallel to the direction of movement of the surface. The rail housing includes a hollow upper or lower portion including a rearward surface and a spaced outer surface. A through hole is formed through such surfaces by a smaller opening in the rearward surface and a larger opening in the spaced outer surface so that the rearward surface forms a fastener retention surface with access there to being obtained through the larger opening. The larger opening may be closed by a flush through hole cap.Type: GrantFiled: March 12, 1999Date of Patent: November 28, 2000Assignee: Jason IncorporatedInventor: Chris M. Davis

Patent number: 6129620Abstract: Honing tools and methods of making such tools utilize a compact bundle of abrasive containing plastic monofilaments projection a relatively short distance from a holder with the compacted tips forming the working face of the tool. The bundle may be secured to the holder by a thin layer of adhesive or by a clinched or swaged girdling lip or rim on the holder which embraces the bundle. In addition, the bundle is further infused with an elastomer, preferably foamed. The bundle is enclosed in a mold which may be part of the clinching process and an elastomer is injected into the mold to infuse and encapsulate the bundle. The encapsulation fills the interstices of the bundle and form an integument around the bundle in effect making the tip action tool into a solid yet elastic block. This enables the abrasive monofilaments to have a higher abrasive loading since they are additionally supported by the matrix, and the tool to be applied at higher pressures.Type: GrantFiled: January 11, 1996Date of Patent: October 10, 2000Assignee: Jason IncorporatedInventors: Rueben Brown Warner, Joseph P. Gaser

Patent number: 5926904Abstract: An abrading tool or brush is formed with an open center low density tuft. The tufts are laterally slightly compressed and encapsulated in a medium density elastomeric foam reinforcement having a density of from about 20 to about 50 lbs/cu/ft (320-800.90 Kg/cu. meter). When the tufts are formed, preferably of wire, they are twisted about a core extending axially of the tufts. The core includes angled facets which form corners around which the wire is bent to form closely spaced bends to promote short fracture of the wire in use.Type: GrantFiled: October 6, 1995Date of Patent: July 27, 1999Assignee: Jason IncorporatedInventor: Rueben Brown Warner

Patent number: 5895612Abstract: An abrasive tool includes a rotatable hub from which extends a bundle of plastic abrasive monofilaments. The bundle has a high filament count and each filament includes a substantial amount of abrasive uniformly entrained therein. After the bundle is secured to the hub, the tool is placed in a mold completely enclosing at least the projecting bundle and a foamable elastomer is injected into the mold to produce a light density cellular matrix bond encapsulating the filaments. The preferred plastic for the plastic monofilaments is nylon 6-12 and the preferred elastomer is a low density (2-20 lbs/cu/ft) polyurethane. The cellular matrix bond for the preferred applications upon wear does not produce a liquid phase at even high tool pressures. Radially extending enlarged coolant passages may be formed during the encapsulation and injection process step. The tool may be in disk, cup or twisted stem form.Type: GrantFiled: January 11, 1996Date of Patent: April 20, 1999Assignee: Jason IncorporatedInventors: Rueben Brown Warner, Joseph P. Gaser

Patent number: 5609398Abstract: A process for forming a twisted stem tool uses a specially designed clamping jaw fixture at the nose or bight portion of a half-round wire or cotter pin which helps to reduce the required clamping force and distribute that force over the entire wire-fill material interface. The jaws of the clamping fixture engage the outside of the nose over a substantial area, and in some forms actually bite into the wire or pin. After the twisting operation, the stem is placed in a swaging or coining press, and the stem beyond the fill material is reformed into a three or six-sided drive stem. The cold flow of the metal to form the flat sides locks the twisted half round wire or pin sections together so that the stem will resist unwinding if the tool is driven in a reverse direction. The coining of the stem providing flats provides a tighter confinement of the bundle of fill material at the stem, and enables a common three or six jaw Jacob's style chuck, for example, to obtain a more secure grip.Type: GrantFiled: October 20, 1994Date of Patent: March 11, 1997Assignee: Jason IncorporatedInventors: Rueben B. Warner, James B. Tyler

Patent number: 5542900Abstract: A composite idler roller has an integral internal bearing surface which interfits with the outer or tread portion of the roller. Flange seals or internal lubricant retaining grooves may be incorporated in the bearing surface. The outer or tread portion of the roller is inserted in a mold concentric with a core pin. The bearing material is injected into the space between the outer portion and the core pin. The centering of the outer portion may be by external contact with the mold or internal shoulder contact with the core pin. The core pin may be wholly or partly collapsible. The roller may have a wide variety of tread styles and may be stud or yoke mounted. In another form, the entire roller is formed of the bearing material.Type: GrantFiled: June 2, 1995Date of Patent: August 6, 1996Assignee: Jason IncorporatedInventor: Thomas F. Burke
