Patent number: 9010310Abstract: A saw apparatus for sawing paving slabs has a frame mounted on a ground contacting propulsion member such that the frame may move above a slab to be cut without touching the slab. A first saw support assembly disposes a blade of a saw in cutting engagement with the slab for a transverse cut. A second saw support assembly disposes a blade of another saw in cutting engagement with the slab for a longitudinal cut. The saws are mounted on the saw assemblies and the saw assemblies are mounted on the frame and the frame is mounted on the ground contact propulsion members such that no part of said frame need contact the slab during cutting.Type: GrantFiled: September 17, 2013Date of Patent: April 21, 2015Inventors: Roger Bockes, Robert Bockes

Publication number: 20150013659Abstract: A tile cutting machine comprises a base, a motor accommodated in the base, a blade driven to rotate by the motor, and a working table supported on the base, wherein the working table comprises a fixed working table fixedly mounted to the base. A movable working table is slidably mounted to the fixed working table in a sliding direction parallel to a plane of the blade. The movable working table comprises a pivoting plate pivotally mounted to the movable working table about a pivoting axis parallel to the plane where the blade is located and a fence assembly mounted to the movable working table. The tile cutting machine can effectively enhance the ability to produce straight and/or square cuts.Type: ApplicationFiled: July 1, 2014Publication date: January 15, 2015Inventor: Zhifeng Chen

Patent number: 8926024Abstract: The motorized cutter with wheels (10) comprises a motorized cutter (20) and a carriage (30). The motorized cutter (20) is equipped with an engine (24), a blade (22) rotatably driven by the engine (24), and a light-emitting unit (50) that generates laser light (52) in the same plane as the plane of rotation of the blade (22). A roadbed (90) is then cut along a line (X) drawn on the roadbed (90) by operating the motorized cutter with wheels (10) so that the line (X) is irradiated with the laser light (52). It is possible to remove the motorized cutter (20) from the carriage (30) together with the light-emitting unit (50).Type: GrantFiled: January 29, 2010Date of Patent: January 6, 2015Assignee: Hitachi Koki Co., Ltd.Inventors: Yukihiro Shima, Kenji Niwa, Shinki Ohtsu, Junichi Kamimura, Mitsuhiro Sunaoshi

Patent number: 8905818Abstract: This invention relates to a process which may be automated for the manufacture of stone blocks for use as finished landscape stone blocks from quarry stone. The natural stone is quarried from the quarry and split into rectangular blocks, with squared ends and the top and bottom surfaces are ground with a plurality of grooves and ridges of varying heights. The ridges of varying heights are then removed thereby producing a surface having ridges of uniform height and grooves of uniform depth. The blocks may be used to form an architectural wall. The process is also applicable to pavers, steps and coping stones.Type: GrantFiled: November 8, 2011Date of Patent: December 9, 2014Inventor: Leon Amsent
