Abstract
Abstract Contour machine in which a worktable is fixed, and enclosed wheels are provided for mounting a band saw, the machine being pivotable with respect to a base, and in which a rotary table, mounted on the worktable, may be automatically set into rotation in the forward or reverse direction or stopped through a curvesensing guide mechanism. The machine body is pivotable with respect to the base in a plane perpendicular to the face of the band saw, together with upper and lower housings which lodge wheels for guiding the band saw. The machine has means to provide an adjustable and reproducible relationship of the body with respect to the base, as well as means for immobilizing the pivoted machine body in various positions. In addition, with a view to attaining savings in manpower and automation of operation, units are provided for indication of the saw tension, for bringing a saw-container housing to a saw-mounting position, for clamping the saw, for adjusting the relative distance between a workpiece and a saw-blade guide mechanism, and a unit for stopping the saw movement upon completion of the machining operation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
212 words
An automatic contour machine comprising, in combinatiOn, a stationary base (12), a machine body (14, 36, 38) pivotable with respect to said base and including means (64 to 68) for immobilizing the same in various positions, said machine body further including an upper housing (36), a lower housing (38) and a housing (40) intermediate the two latter, a stationary worktable (28) mounted on said base about the same height as said intermediate housing, means (16, 18) in said upper and said lower housings for rotatably supporting a band saw (20) and the like cutting tool for pivotal movement together with said machine body, including said housings, in a plane perpendicular to the face of the band saw, said supporting means including a pair of wheels (16, 18) for guiding the band saw, drive means for operating the same, said lower housing being lodged and pivotable within said base, the latter including, at a level above said lower housing but below said worktable, a pair of ball-joint type supports (44, 44'') about which can pivot a pair of socket-type fixtures (42, 42'') secured to the upper surface of said lower housing, and means (46 to 62) for providing an adjustable and reproducible pivotal relationship of said machine body with respect to said base.
Claim 2
Dependent Claim
212 words
An automatic contour machine comprising, in combinatiOn, a stationary base (12), a machine body (14, 36, 38) pivotable with respect to said base and including means (64 to 68) for immobilizing the same in various positions, said machine body further including an upper housing (36), a lower housing (38) and a housing (40) intermediate the two latter, a stationary worktable (28) mounted on said base about the same height as said intermediate housing, means (16, 18) in said upper and said lower housings for rotatably supporting a band saw (20) and the like cutting tool for pivotal movement together with said machine body, including said housings, in a plane perpendicular to the face of the band saw, said supporting means including a pair of wheels (16, 18) for guiding the band saw, drive means for operating the same, said lower housing being lodged and pivotable within said base, the latter including, at a level above said lower housing but below said worktable, a pair of ball-joint type supports (44, 44'') about which can pivot a pair of socket-type fixtures (42, 42'') secured to the upper surface of said lower housing, and means (46 to 62) for providing an adjustable and reproducible pivotal relationship of said machine body with respect to said base.
Claim 3
Dependent Claim
84 words
The automatic contour machine as defined in claim 1, further comprising saw storage means (26, 196, 198, 202) in said machine body (14), including a support (202) pivoted to said machine body, a container (198) pivoted to said support, and at least one casing (196) in said container for lodging therein the band saw (20) wound in at least one spiral, and saw cutter means (188) on said machine body, to which the band saw can be extended from said at least one casing.
Claim 4
Dependent Claim
