Abstract
A cutting system for accurately cutting a notch in a piece of lineal to permit sharp bending of the lineal, permitting the lineal to be placed about the perimeter of picture or similar structure is disclosed. The cutting system includes a handle for driving a cutting blade in the direction of the force of gravity, and includes a retracting mechanism to return the handle and cutting blade to an initial starting position after each cut. A laterally reversible measuring assembly consisting of a measuring guide barn and a pair of adjustable measuring stops for measuring and supporting a piece of lineal to be cut, is releasably secured to the cutting system, facilitating interchange between left and right lateral configurations.
Claims18
A cutting mechanism for cutting a workpiece comprising:
- a base member having a receptacle for receiving the workpiece;
- a clamping device, said clamping device positioned to hold the workpiece;
- a cutting blade, the cutting having an inverted-V configuration and disposed in a vertical orientation;
- a laterally reversible measurement system associated with said base, said measuring system configured to facilitate a plurality of sequential cuts in said workpiece by said cutting blade at predetermined measurements along said workpiece;
- a lever operatively connected to said cutting blade, said lever operating said cutting blade vertically between a retracted position and a cutting position, said lever positioned in a plane perpendicular with respect to said base member for actuation in the direction of gravity as said cutting blade is operated between said retracted position to said cutting position;
- and
- a return mechanism associated with said lever, said return mechanism configured to return said lever and said cutting blade to said retracted position.
A workpiece cutting device comprising:
- a base member;
- a reciprocating cutting blade movably mounted on said base member in a vertical orientation;
- a cutting blade actuator mounted to said base member, said cutting blade actuator cycling said reciprocating cutting blade between a retracted position and an extended position, said cutting blade actuator including a handle movable in an arc perpendicular to said base member in the direction of gravity between an upward position in relation to said base member and a lower position in relation to said base member;
- a return mechanism biasing said handle toward said retracted position;
- a jig for receiving said workpiece, said jig configured to permit cutting of said workpiece by said cutting blade;
- and
- a laterally reversible measurement system associated with said base member, said measurement system configured to facilitate the making of a plurality of sequential predetermined measured cuts in said workpiece.
A method of framing an object having a generally parallelogram shape, comprising the steps of:
- setting a first indicated position representative of the length of first side of said object;
- setting a second indicated position representative of the length a second side of said object, said second side adjacent said first side;
- (a) laterally placing an edge material, defining an object receiving channel, at said first indicated position;
- (b) holding said edge material in position against a vertically orientated base member;
- (c) actuating a cutting member in a downward motion perpendicular to said vertically orientated base member to cut said edge material in the direction of gravity with a generally “V” shaped cut, said edge material retaining a carrier portion along a vertex of the “V”;
- (d) releasing said edge material;
- (e) laterally placing said edge material at said second indicated position relative to said previous cut at said first indicated position;
- (f) repeating steps (b) through (d);
- repeating steps (a) through (f) as initially measured from said previous cut at said second indicated position;
- cutting said carrier portion of the last cut to separate a lineal length from said edge material;
- and
- placing said lineal length of edge material about a peripheral edge of said object.
