Patent number: 8365714Abstract: A tile cutting machine includes a tub for receiving water and a tile supporting surface for supporting thereon a tile to be cut. A cutting head assembly is positioned above the tile supporting surface and includes a motor driven blade. A tile hold down mechanism extends downwardly from the cutting head assembly to engage the tile and apply downward pressure thereto to hold the tile in place during the cutting process. The tile hold down mechanism may take the form of flexible hold down feet, downwardly biased rollers and/or bristle skirts. The tile supporting surface may be fabricated of a high friction material and include a plurality of nubs to cooperate with the hold down mechanism to hold the tile stationary with respect to the supporting surface during the cutting process. The tile cutting machine provides for a method of cutting tile where a user does not have to hold the tile with their hands during the cutting operation.Type: GrantFiled: May 23, 2011Date of Patent: February 5, 2013Assignee: Black & Decker Inc.Inventors: Robert H. Gifford, Marco Alessandro Mattucci, Jason Carl McRoberts, Brent Austin Kuehne, Micah Alan Coleman, Michael Frederick Cannaliato, Weston John Van Wambeke, Jeff Whitehead

Patent number: 7946906Abstract: A tile cutting machine includes a tub for receiving water and a tile to be cut therein. A cutting head assembly having a motor driven blade is positioned above a tile supporting surface located in the tub and is movable with respect thereto. A laser projects a line of light from the cutting head assembly down onto the tile supporting surface to provide a visual representation of a cutting path of the blade. A scale permits measurement of a tile to be cut. The laser may be used with the scale to allow a user to quickly determine cutting widths without the need to manually mark the object to be cut. A light source, such as an LED, may be incorporated in the cutting head to illuminate an interior of the tub during operation of the tile cutting machine.Type: GrantFiled: August 22, 2007Date of Patent: May 24, 2011Assignee: Black & Decker Inc.Inventors: Robert H.

The rail bearing includes a housing having a bore therethrough. A plurality of slots are located in the housing adjacent the bore. The slots receive an axle pin having a wheel thereon to provide a roller bearing. Portions of the wheels extend into the bore and ride along an outer surface of the rail when it is received in the bore.Type: GrantFiled: August 22, 2007Date of Patent: October 12, 2010Assignee: Black & Decker Inc.Inventors: Robert H. Gifford, David Charles Campbell, Jason Carl McRoberts, Brent Austin Kuehne, Micah Alan Coleman, Michael Frederick Cannaliato, Terry L. Turner
