20090145978 | PORTABLE TEXTURE-SPRAYING APPARATUS FOR UNIFORMLY DISPERSING A VISCOUS MATERIAL - This invention is related to a portable texture-spraying apparatus for uniformly dispersing a viscous material. This apparatus broadly includes a tank assembly having a body with an inner wall that defines a sealed cavity, and a piston assembly slidably disposed within the sealed cavity. The piston assembly divides the sealed cavity into an air-side chamber and a material-side chamber by providing an airtight seal therebetween. Additionally an air-control assembly is provided that broadly includes a pressure-control mechanism configured for receiving compressed air and routing a controlled pneumatic pressure to a directional valve configured for adjusting between a dispensing mode and a loading mode. In dispensing mode, the directional valve routes the controlled pneumatic pressure to the air-side chamber biasing the piston assembly toward the material-side chamber. In loading mode, the directional valve releases the air-side chamber to the atmosphere allowing for filling the material-side chamber with viscous material. | 06-11-2009 |
20090145416 | ADAPTABLE TILE-CUTTER APPARATUS FOR RECEIVING DISPARATELY-SIZED TILES - This invention is related to an adaptable tile-cutter apparatus for scoring and breaking disparately-sized tiles. The apparatus broadly includes: a pair of end castings removably; a rigid crossbeam and a travel rail spanning the pair of end castings; vertical-adjustment mechanisms mounted to the travel rail; one or more platform assemblies each coupled to the rigid crossbeam; and a cutting mechanism slidably engaged to the travel rail. The vertical-adjustment mechanisms individually adjust a height of the travel rail with respect to the pair of end castings. In addition, the rigid crossbeam and the travel rail comprise a first matched set, and are each removably coupled to the pair of end castings. Accordingly, a second matched set that includes another rigid crossbeam and another travel rail possessing lengths at variance with the rigid crossbeam and the travel rail of the first matched set may be interchanged therewith. | 06-11-2009 |
20090139380 | ADJUSTABLE TOOL HANDLE - An adjustable handle and method of adjusting the cross-sectional shape of a handle is disclosed. The handle comprises a central core having a plurality of axially extending grooves each having at least two radially extending ramps as well as a sleeve having a plurality of flexible expandable members with a plurality of fins in sliding relationship with the axially extending grooves and ramps. When a user turns a knob of the handle, the sleeve is directed to slide axially within the groove such that the fins of the flexible expandable members contact the ramps thereby altering the cross sectional shape of the handle over an axial distance. | 06-04-2009 |
