Patent number: 6129616Abstract: The invention comprises a device for sharpening cutting tools, such as knives, scissors, etc., with an abrasive or steel piece. The device is characterized by a U-shaped body formed as an open handle and having on its underside a supporting or bracing surface. The U-shaped body is equipped with a projecting piece receiver extending toward the front of the device and designed to hold the abrasive or steel piece. Below the receiver is a ceramic rod which can be shifted lengthwise toward the front and which serves to smooth irregularities in the cutting tool edge being sharpened.Type: GrantFiled: February 23, 1999Date of Patent: October 10, 2000Assignee: Heinz WeschenfelderInventor: Adolf Klotz

Patent number: 5951378Abstract: A method is provided for machining the fire deck of an engine block. The method includes providing a grinding wheel having an outer annular grinding element disposed concentrically or the wheel may be provided with an inner annular grinding element disposed concentrically inward of an outer element. The outer element comprises a single layer of relatively coarse diamond abrasive brazed on a metallic substrate, while the inner element comprises a single layer of relatively fine diamond abrasive brazed on a similar substrate. The outer grinding element and the inner element if utilized, is formed as a discrete unit individually fastened to a backing plate to facilitate independent height adjustment of the elements relative the backing plate. The method further comprises orienting the grinding wheel with its axis of rotation at a predetermined oblique angle a relative the fire deck.Type: GrantFiled: August 7, 1997Date of Patent: September 14, 1999Assignee: Norton CompanyInventors: Bradley J. Miller, Richard F. Buckley, David M. Duarte, John Hagan, Mianxue Wu

Patent number: 5944586Abstract: Apparatus and method for both cleaning and polishing work surfaces such as automotive panels using a single combination pad. In one embodiment, a support holds a circular replaceable, disposable cleaning/polishing pad on a powered polishing tool for rotation about the pad's central axis. The illustrated pad is made of compressible/expandable material such as foam. The pad has front and rear recesses that define concentric radially outer and inner sections. The inner section is thinner and has a forward cleaning surface. The outer section normally protrudes forwardly of the cleaning surface so that when it is first brought into engagement with a work surface, the cleaning surface does not engage the work surface. A pressure-applying backup plate of a firm material such as neoprene has a forwardly displaced inner portion that is received in the pad rear recess for applying firm pressure to the pad cleaning surface. The plate has an outer portion for applying pressure to the outer pad section.Type: GrantFiled: May 8, 1998Date of Patent: August 31, 1999Assignee: Meguiar's Inc.Inventors: Claude Sevigny, David M. Hornby

Patent number: 5941761Abstract: An end effector to facilitate conditioning of a surface of a polishing pad used in chemical-mechanical polishing of an substrate surface is described. The end effector includes a rigid body including a contact surface capable of being attached to a conditioning disk and having a predetermined non-planar region that is adapted to at least one of (i) effectively maintain a non-planar area on the surface of the polishing pad and (ii) shape the polishing pad, when the end effector is employed to condition the polishing pad.Type: GrantFiled: August 25, 1997Date of Patent: August 24, 1999Assignee: LSI Logic CorporationInventors: Ronald J.

Patent number: 5885139Abstract: A power-operated and hand steerable machine for stripping linoleum, tile, mastic, grout, adhesive and the like from a floor and also for re-surfacing the floor after the stripping operation. The machine includes a support frame, a drive plate driven by a motor about a vertical rotational axis, a reversible work plate mounted under the drive plate and carrying cutter blocks with cutter inserts at one face and abrasive-carrying devices at the opposite face. Therefore, after a floor stripping operation by the cutter inserts, the work plate can be reversed and a floor re-surfacing operation be carried out by using the abrasive-carrying devices. A change speed system enables to drive the work plate at a higher speed during floor re-surfacing than during floor stripping. Longitudinally adjustable weights are carried by the support frame to adjustably bias the work plate against the floor.Type: GrantFiled: July 15, 1997Date of Patent: March 23, 1999Inventors: Francois Lemieux, Claude Bissonnette

Patent number: 5871394Abstract: A floor sander having a number of interchangeable sanding head assemblies for sanding a surface such as a hardwood floor. Each of the interchangeable sanding head assemblies includes a sanding implement which may provide differing levels of sanding or other surface action. The desired sanding head assembly is attached with a main housing of the floor sander using a connect assembly attached to each of the sanding head assemblies. A plurality of locking devices mounted within each connect assembly engages an equal number of locking pins extending from the main housing to secure the sanding head assembly to the main housing. An alignment device is provided on the main housing to insure proper alignment of each sanding head assembly with both the drive motor and the surface to be sanded.Type: GrantFiled: December 12, 1997Date of Patent: February 16, 1999Assignee: Floor Style Products, Inc.Inventors: Bryan Mattson, Michael T.
