The blank is then placed into a circular die having forming punches associated therewith to strike the blank to form finger grip indentations therein. The circular die is then rotationally indexed so that the forming punches can form subsequent finger grip indentations around the circumference of the blank adjacent to the previously formed indentations in a predetermined pattern until the steering wheel rim is completed. By utilizing multiple, preferably three, forming punches equidistantly spaced along the circumference of the circular die, the finger grip indentations can be formed without crushing the blank.Type: GrantFiled: January 23, 2002Date of Patent: June 8, 2004Assignee: Schmitt Marine Steering Wheels, Inc.Inventor: Gervase G.

Patent number: 6745469Abstract: A screen media (200) for use in screening pulp slurry has a first side (204) and a second side (206). The pulp slurry is fed from the first side of the screen media to the second side of said screen media through a plurality of screening passages (205). Each said screening passage include a contour cut (210) formed in the first side, a back groove (208) formed in the second side, and a residual thickness (234) between the contour cut and the back groove. An elongate slot (235) is formed in the residual material, and the residual thickness has a substantially uniform thickness about the elongate slot. Where the slot extends completely through the residual material it defines a through-slit (236) through which slurry flows and is filtered.Type: GrantFiled: October 30, 2000Date of Patent: June 8, 2004Assignee: J&L Fiber Services, Inc.Inventors: Matthew R.

Patent number: 6745473Abstract: A cable sheathing slitter attachment for a wire stripper tool. The cable sheathing slitter attachment is preferably integrally formed of sheet metal and a blade member and a guard member. The blade member includes a blade portion having first and second oppositely facing knife-edges and a mounting portion having an opening that facilitates the mounting of the blade member to a jaw of the wire slitter tool. The guard member includes a mounting portion with a hole therethrough and a U-shaped guard portion. A fastener passes through the hole in the mounting portion of the guard member, the elongated opening in the mounting portion of the blade member and through the hole in the respective jaw to mount the guard and blade members to the jaw of the wire stripper tool. The guard is rotatable with respect to the knife-edges to expose the knife-edges when it is desired to use the same for the slitting of non-metallic sheathed cables.Type: GrantFiled: July 18, 2002Date of Patent: June 8, 2004Inventor: Patrick F. Lawler

Patent number: 6745474Abstract: A cutting knife includes a holder with a slot defined in a side thereof and a plurality of recesses defined in one of two sides of the slot. A base member is slidably engaged with the slot and a blade is connected to the base member. The base member has a wall in which a spring member is received. The spring member includes a protrusion which extends through an opening defined in the wall and is engaged with one of the recesses. A spring is biased between an inside of the wall and a reverse side of the protrusion of the spring member so as to provide a force to engage the protrusion in the recess. Two end portions of the spring member contact against the insides of the wall. An operation member is slidably mounted to the wall and includes a wedge-shaped notch which may push the protrusion downward to disengage from the recess.Type: GrantFiled: December 17, 2002Date of Patent: June 8, 2004Inventor: Chien Kai Huang

Patent number: 6745476Abstract: A cutting tool (10) adapted to produce chamfers along the edges of drywall panels. The tool (10,110,210) comprises a housing having a channel (18) defined by a base wall (13) and substantially parallel first and second sidewalls (15,17) that are substantially perpendicular to the base wall (13). A primary cutting blade (30) extends from the first sidewall (15) at an angle across the channel (18) toward the second sidewall (17). The primary blade (30) is configured to cut through an edge of a panel placed in the channel (18) as the cutting tool (10,110,210) is caused to move along the edge of the panel, thereby creating a chamfered edge on the panel. A second cutting blade (32) also extends from the first sidewall (15) and is positioned adjacent the primary blade (30) to create a perforation in the edge of the panel prior to the panel encountering the primary blade (30).Type: GrantFiled: January 30, 2003Date of Patent: June 8, 2004Inventor: William Korba, Jr.
