Abstract: A cutting angle adjustment device for a stone cutter includes a rectangular water sink, an inverse L-shaped support arm anchored to a lateral side of the sink, a stone cutter adjustably connected to the support arm through a coupling assembly, a pair of guide rods parallel disposed to a pair of rack on front and rear ends of the sink, a platform having two rotors aligned to each other and symmetrically arranged and slidably engaged with the inner sides of the guide rods, a vertical cutting slit and a slant cutting slit parallel formed in the upper surface thereof. Thereby, a saw blade is adjusted vertically and/or slantly relative to the top of the platform to conduct a vertical or slant cutting and a shallow or deep cutting of the workpiece.

Abstract: A cutting mechanism minute adjustment device for a stone cutter includes a framed base having a hollow interior rectangular support arm on a front corner including a sustaining plate fixed therein inserted into a rectangular receiving spaced under a left portion of a cutting mechanism with a L-shaped adjustable plate engaged therebetween. The adjustable plate has a rectangular through holes for passing through the support arm and a pair of adjustable slots engaged with a pair of screw holes under the cutting mechanism and releasably secured by a pair screws. The cutting mechanism further has a circular blade on a right side actuated by a motor therein and a screw hole in a left wall communicating to the rectangular space and a U-shaped slit in a top of the support arm. A lock has a threaded shank on front engaged into the screw hole and the receiving space of the cutting mechanism through the U-shaped slit of the support arm.

Abstract: A blade angle adjustment device for a stone cutter includes a framed base having a working table slidably disposed on the base including a vertical cutting groove and a slant cutting groove in upper surface, a tool plate and a support arm respectively secured to a lateral side thereof, a L-shaped link having pair of screw holes in a longitudinal portion engaged with a screw hole and oblong hole on the top of the support arm and secured by a screw and a first swivel lock, a screw hole and an arcuate slot in a transverse portion respectively engaged with the front ends of a large and a small internally threaded large and small connection rods and secured by a second swivel lock and a handled screw, a motor protected by an upper housing and a lower housing which is connected to the rear end of the connection rods and a guarded circular blade connected to an axis of the motor so that slides the first swivel lock in the oblong hole to define the elevational angle for the cutting mechanism and slides the small conn

Abstract: An improved portable stone cutter includes a base which is of a rectangular frame composed of a plurality of longitudinal bars, a pair of transverse bars and a pair sliding bars, a working table slidably secured to the sliding bars, a motor disposed on the front end of the frame and sustained by an arcuate support arm and a supplementary support arm which are releasably and rotatably secured to a pair of outmost longitudinal bars, a guarded circular saw blade connected to the motor and operated by the motor via a belt and a transmission shaft and a tool plate movably disposed to one of the outmost longitudinal bars. The feature is that the arcuate support arm and the supplementary support arm define a large space to permit a large piece of stone passing through the saw blade and both the supplementary support arm and the tool plate are removable to reduce the volume of the stone cutter to conveniently pack for transportation.

Abstract: A structurally improved stone cutter including a rectangular frame supported by a foldable stand, a rectangular sink in the frame, a rectangular platform having sliding devices on two end slidably engaged with a pair of guide rods of the frame, a brace secured to a corner of the frame for supporting a positioning plate on the top, a motor positioned on a top having a first wheel on one end, a tubular shaft releasably secured to an underside of the positioning plate opposite to the motor and having a spindle therein supported by bearings, a second wheel secured to one end of spindle, a fan cap and a saw blade secured to the other end of the spindle, a belt tensely wrapped on the first and second wheels, a blade guard positioned on the top of the saw blade and secured on one end to an outer lateral surface of the positioning plate and a working station having a L-shaped edge releasably engaged into the gap of the frame.

Abstract: A stone cutter has a sink standing upon a callapible support, a frame disposed on the sink including an upright at a corner portion and a guide rod longitudinally secured in the frame, a platform including a tubular slider of splined inner periphery sliding on the guide rod and plurality of pulleys on the other side slidable on the frame, a housing including a sleeve sleeved on the upright of the frame, a switch, an indicator transversely disposed in the housing positioned opposite to the sleeve, a saw blade secured to an axis of the motor and a casing covering the upper portion of the saw blade having one end rotatably secured to the housing and a pair of water suppliers on two side to provide water to clean the dust from a working piece during the operation of the stone cutter.
