There is a floor on which a second surface, the narrow edge, of the workpiece that is transverse to the workpiece first surface is to rest that is vertically adjustable relative to the guide channel exit, and an adjustable screw clamp threaded in the clamp leg to engage a third surface of the workpiece opposite the workpiece first surface to hold the workpiece first surface against the interior surface of said guide leg during the time a drill bit is advanced in the guide channel to the workpiece first surface.Type: GrantFiled: August 17, 2004Date of Patent: September 5, 2006Assignee: Simp'l Products, Inc.Inventors: Burton Weinstein, Richard H. Deaton

Patent number: 7094008Abstract: A portable combined clamp and bit guide assembly guides a bit, turned by a power driver, into the exact center between the opposing faces of the clamp. The clamp is designed to hold workpieces having substantially parallel edges and a substantially linear centerline on their upper surfaces, and provides a drill path perpendicular to that centerline. An optional incline adapter supports the clamp and bit guide at an angle to the workpiece, while also aiding in support of the workpiece itself. The entire assembly may be carried in a single case with a power driver and bits.Type: GrantFiled: June 1, 2004Date of Patent: August 22, 2006Inventor: William Richard Hartsfield, Jr.

Patent number: 7073991Abstract: An installation jig has a body member and a clamping mechanism. The clamping mechanism along with the body are clamped onto a door. The body includes a plurality of walls with one wall having an aperture enabling passage of a tool which may drill a hole into a door at a desired standard lock set size. Also, the body includes an aperture to enable a lock bolt hole to be drilled into the door at a plurality of standard door thickness.Type: GrantFiled: February 16, 2005Date of Patent: July 11, 2006Assignee: Black & Decker Inc.Inventor: Rickey J Thomas

Patent number: 7066690Abstract: A boring apparatus and method for in-situ repair of motor vehicle axles includes a universal mounting plate assembly for attachment to a vehicle axle, both longitudinal (on-axis) and transverse (radial) adjustment assemblies, a bearing assembly and a boring bar and drive assembly having a pair of motor drive units for rotating (speed) and axially advancing (feed) the boring bar. The longitudinal and transverse adjustment assemblies facilitate use of the boring apparatus on a wide variety of vehicle and truck axles from virtually all manufacturers to repair broken axles or damaged bearing surfaces.Type: GrantFiled: July 22, 2003Date of Patent: June 27, 2006Assignee: Precision Machining Corp.Inventor: James L. Ebert

Patent number: 7048478Abstract: Composable machine tool for chip removal, on major workpieces, within wide diameter and/or great length clearance holes, made up of a shaft (1) upon which a machine base, controlled by a first engine (50) for the rotation movement and by a second engine for the translation movement, upon which are mounted the design tool elements. On the shaft (1) two support bearings (15) are mounted on both sides of the workpiece (29), all have spokes (16) each of which have radial slots (17) in which the groups (33) are inserted, regulated and locked to tighten the workpiece, on the shaft, a hydraulic jack (34) is mounted at least on one side, at the two extremities of the shaft (1), two slotted shoulders (40) are mounted to allow the jack (34) to exert the necessary pressure to lock the workpiece.Type: GrantFiled: January 17, 2001Date of Patent: May 23, 2006Inventor: Evangelista Russo

Patent number: 7001118Abstract: A dowel jig for making holes in a member such as a board to accept dowels for projecting toward corresponding holes for receiving the dowels to make butt, end and T type dowel joints for two members. The jig has a base having an internal planar area and at least one hole transversely through the planar area and a transverse leg at each end of the base. A foot is at the outer corner junction of each base end and transverse leg and the lower surfaces of both feet lie in a common plane that is parallel to the base internal planar area so that when the lower surfaces of the feet are placed on the flat upper surface of a member the base hole will be transverse to the flat surface to permit aligned passage of a drill bit to drill a hole in the member transverse to the flat surface. Notches are provided in each of the feet along a line that passes through the hole center to hold a rod in which a hole is drilled.Type: GrantFiled: January 13, 2004Date of Patent: February 21, 2006Assignee: Simp'l Products, INCInventors: Burton Weinstein, Richard H. Deaton

Patent number: 6994498Abstract: A lockset drilling guide and a method of forming holes in a door are provided. The drilling guide includes a frame and at least a first opening and a second opening defined in the frame. The first opening is positioned at approximately 90 degrees to the second opening. The frame is configured for positioning on a door to facilitate the forming of openings in a door for the installation of a lockset. The method includes the steps of providing a frame having at least a first opening and a second opening defined in the frame; positioning the frame on an edge of the door; inserting a first holesaw at least particularly into the first opening and drilling a first hole in the door; inserting a second holesaw at least partially into the second opening and drilling a second hole in the door; and removing the frame from the door.Type: GrantFiled: December 22, 2004Date of Patent: February 7, 2006Assignee: Irwin Industrial Tool CompanyInventors: David J. Trettin, Richard M. Davidian, Laverne Durfee, Kristofor M. Hallee

Patent number: 6981911Abstract: An abrasive drill bit and method of use on glass, ceramics, tile, stone and similar solid materials, both natural and synthetic. A circle is ground into the material using a cylindrical drill bit, which grinds a loose abrasive between the bit cylinder and the material. When the circle is complete, a punch-out piece of the material falls out, leaving a smooth hole. Alternatively, the loose abrasive is ground between a solid bit and the material to grind out a hole. In both methods, the loose abrasive is preferably mixed with water to form a slurry.Type: GrantFiled: April 28, 2003Date of Patent: January 3, 2006Inventor: Jose-Maria Vidal Martina

Patent number: 6948720Abstract: A computer controlled positioning table for use in automatically rotating a large diameter article into which an evenly spaced circle of bolt holes are to be drilled. The article to be drilled is centered and clamped onto a table top of the table and then the computer rotates the table top incrementally to precisely position the article relative to an associated stationary drill stand that is used to drill the desired holes in the article. Rotation of the table top is computer controlled, allowing the operator to select the number of bolt holes for each article. Once the table top has rotated to the proper position, locking mechanisms and support roller provided under the table top hold the table top stationary in the proper position while a hole is drilled in the article.Type: GrantFiled: December 10, 2002Date of Patent: September 27, 2005Inventor: James D.
