Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
157 words
An automatic sawing machine for the production of shaped sections of predetermined dimensions from rough plates and the like sheet material, comprising a platform having longitudinal and transverse dimensions for supporting the sheet material to be sawed, a crossmember above the platform having spaced supports respectively at the longitudinal sides of the platform and movable longitudinally along the platform, a transversely movable support carried by the crossmember for movement across the platform, a vertically movable shaft carried by the transversely movable support, a vertically movable saw unit mounted on and rotatably fixed with respect to said shaft, means in the transversely movable support for raising and lowering the shaft and the saw unit carried thereby and for rotating the shaft about its axis when in raised position, and means for automatically stopping and locating the saw unit at a predetermined angular position with respect to the platform when the saw unit is in its lowered working position.
Claim 2
Dependent Claim
157 words
An automatic sawing machine for the production of shaped sections of predetermined dimensions from rough plates and the like sheet material, comprising a platform having longitudinal and transverse dimensions for supporting the sheet material to be sawed, a crossmember above the platform having spaced supports respectively at the longitudinal sides of the platform and movable longitudinally along the platform, a transversely movable support carried by the crossmember for movement across the platform, a vertically movable shaft carried by the transversely movable support, a vertically movable saw unit mounted on and rotatably fixed with respect to said shaft, means in the transversely movable support for raising and lowering the shaft and the saw unit carried thereby and for rotating the shaft about its axis when in raised position, and means for automatically stopping and locating the saw unit at a predetermined angular position with respect to the platform when the saw unit is in its lowered working position.
Claim 3
Dependent Claim
30 words
A sawing machine as claimed in claim 1, wherein the stopping means includes a jig connected with respect to said transversely movable support and provided with recesses at 90* intervals.
Claim 4
Dependent Claim
36 words
A sawing machine as claimed in claim 2, wherein the recesses of the stopping jig are oriented to provide for saw cuts parallel to and at 90* with respect to the longitudinal sides of the platform.
Claim 5
Dependent Claim
34 words
A sawing machine as claimed in claim 2, wherein the shaft carries a jaw coupling extending therearound and provided with projections adapted to fit in and accurately engage the recesses in the stopping jig.
Claim 6
Dependent Claim
75 words
A sawing machine as claimed in claim 2, wherein the stopping jig is adjustable vertically with respect to the transversely movable support for in turn adjusting the vertical position of the saw unit, and plate clamps provided with longitudinal belts adapted to engage the plate being sawed, said plate clamps being located respectively on opposite sides of the saw unit and including a pressure loaded parallelogram structure biasing the belts against the plate being sawed.
