Abstract
Abstract A self-gauging mitre saw is disclosed for cutting molding to fit the sides of a pattern piece. A hydraulically operated gauging plate is actuated to retain the pattern piece against a reference. Each of a pair of selectively utilized stops is mechanically associated with the gauging plate and travels therewith. The pair of stops travel within a channel, which channel is also adapted to receive the molding to be cut. A vertically selectively movable mitre saw assembly is disposed relative to the channel to intersect and cut the molding disposed therein as the mitre saw assembly descends. In operation, the pattern piece is secured against its reference by the gauging plate. Movement of the gauging plate will also cause each of the pair of stops to move toward the mitre saw assembly. The piece of molding to be cut to fit the pattern piece is inserted within the channel up to the actuated one of the pair of stops. In this position, the length of molding extending between the mitre saw assembly and one of the pair of stops is equal to the length of the pattern piece intermediate its reference and the gauge plate. The mitre saw assembly is actuated and caused to descend and cut the molding to the measured length.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
230 words
A self-gauging mitre saw apparatus mounted upon a work table for cutting molding to a length equivalent to the distance between opposing first and second sides of a pattern piece, said apparatus comprising in combination: a. a channel secured to the work table for receiving a length of molding; b. a vertically movable dual cut mitre saw assembly having a pair of cutting blades set at an angle of 90* with respect to one another, said cutting blades being at angles of 45* and 135*, respectively, with respect to said channel, said saw assembly being selectively movabLe in the vertical axis to intersect said channel; c. an upwardly extending reference point fixedly attached to the work table in proximity to said saw assembly for defining the position of the first side of the pattern piece; d. a slideable gauge plate having a gauge extending lateral therefrom, said gauge plate being slideable parallel to said channel to position said gauge adjacent the second side of the pattern piece; and e. a stop disposed within said channel for limiting the length of molding to be cut by said saw assembly, said stop being secured to said gauge plate and slideable therewith within said channel; whereby, the gauge plate automatically determines the length of molding to be cut to conform with the distance between the first and second sides of the pattern piece.
Claim 2
Dependent Claim
230 words
A self-gauging mitre saw apparatus mounted upon a work table for cutting molding to a length equivalent to the distance between opposing first and second sides of a pattern piece, said apparatus comprising in combination: a. a channel secured to the work table for receiving a length of molding; b. a vertically movable dual cut mitre saw assembly having a pair of cutting blades set at an angle of 90* with respect to one another, said cutting blades being at angles of 45* and 135*, respectively, with respect to said channel, said saw assembly being selectively movabLe in the vertical axis to intersect said channel; c. an upwardly extending reference point fixedly attached to the work table in proximity to said saw assembly for defining the position of the first side of the pattern piece; d. a slideable gauge plate having a gauge extending lateral therefrom, said gauge plate being slideable parallel to said channel to position said gauge adjacent the second side of the pattern piece; and e. a stop disposed within said channel for limiting the length of molding to be cut by said saw assembly, said stop being secured to said gauge plate and slideable therewith within said channel; whereby, the gauge plate automatically determines the length of molding to be cut to conform with the distance between the first and second sides of the pattern piece.
Claim 3
Dependent Claim
108 words
The apparatus as set forth in claim 1 wherein: a. said gauge plate includes two gauges, a first gauge for pattern pieces of up to a first length and a second gauge for pattern pieces of a length greater than said first length; b. said stop including a first stop associated with said first gauge and a second stop associated with said second gauge; and, c. said first stop including means for raising and lowering said first stop within said channel; whereby, said first stop is raised to prevent the molding from sliding therepast and lowered to allow the molding to slide therepast to contact said second stop.
Claim 4
Dependent Claim
34 words
The apoparatus as set forth in claim 1 wherein the face of said stop in contact with the molding inserted within said channel is at an angle of 45* with respect to said channel.
Claim 5
Dependent Claim
48 words
The apparatus as set forth in claim 2 wherein each of said gauges includes threaded adjustment means for matching the distance between the blades of said saw assembly and said first and second stops to the distance between said reference point and said first and second gauges, respectively.
Claim 6
Dependent Claim
43 words
The apparatus as set forth in claim 4 wherein said channel includes a pair of thumb notches disposed in proximity to said mitre saw assembly for providing access to the molding to aid in positioning the molding adjacent one side of said channel.
