Ironworker

Claim 2

An ironworker for punching, notching, shearing and like operations on structural members having extreme lengths and varied forms and shapes comprising a frame, a ram and striker mounted on said frame, a turret rotatably mounted on said frame and having a plurality of tools, including a punch and die, circumferentially spaced thereon and positionable selectively beneath said striker, means for supporting the structural member beneath said striker, means for locating said structural member along a first axis beneath the striker, and gaging means for locating the structural member along a second axis beneath the striker whereby accurate and rapid operations can be made on the structural member without manual measurements on the structural member.

Claim 3

An ironworker for punching, notching, shearing and like operations on structural members having extreme lengths and varied forms and shapes comprising a frame, a ram and striker mounted on said frame, a turret rotatably mounted on said frame and having a plurality of tools, including a punch and die, circumferentially spaced thereon and positionable selectively beneath said striker, means for supporting the structural member beneath said striker, means for locating said structural member along a first axis beneath the striker, and gaging means for locating the structural member along a second axis beneath the striker whereby accurate and rapid operations can be made on the structural member without manual measurements on the structural member.

Claim 4

An ironworker for punching, notching, shearing and like operations on structural members having extreme lengths and varied forms and shapes comprising a frame, a ram and striker mounted on said frame, a turret rotatably mounted on said frame and having a plurality of tools, including a punch and die, circumferentially spaced thereon and positionable selectively beneath said striker, means for supporting the structural member beneath said striker, means for locating said structural member along a first axis beneath the striker, and gaging means for locating the structural member along a second axis beneath the striker whereby accurate and rapid operations can be made on the structural member without manual measurements on the structural member.

Claim 5

The ironworker of claim 1, said gaging means including a sliding end gage engageable by the structural member for movement along said second axis, a pointer on said frame for indicating the location of the striker along said second axis, and elongated measuring means having measured graduations visible at said pointer and movable with said sliding end gage whereby movement of said sliding end gage by said structural member causes said graduations to pass said pointer for measuring the location of said structural member in said second axis.

Claim 6

The ironworker of claim 2, said gaging means including means biasing said sliding end gage into alignment with said pointer.

Claim 7

The ironworker of claim 3, said gaging means including guide means along Said second axis, said sliding end gage having guide rollers mounted on said guide means for carrying the sliding end gage along said guide means, said elongated measuring means including a flexible tape coupled to said sliding end gage and automatically retractably mounted for movement along said second axis, said biasing means including a pair of elongated cords spring biased in opposite directions and each having an enlargement secured thereto, a pair of stops holding each enlargement against movement in said respective biased direction past the plane of the fixed pointer, and means on said sliding end gage selectively engageable with one of said enlargements for removing the enlargement from said respective stop to pull the cord against said spring bias so that the spring bias will return the sliding end gage to a neutral position aligned with the fixed pointer when the structural member is removed.

Claim 8

The ironworker of claim 4, said means for locating the structural member along said first axis including means for positioning the structural member supporting means along said first axis, said means for supporting the workpiece including a plurality of rollers rotatably mounted for rotation about axes parallel to said first axis, said means for positioning the supporting means along said first axis including an axle, crank means for rotating said axle, and means coupling the axle with said supporting means for movement along said first axis upon rotation of said axle.

Claim 9

The ironworker of claim 1, including a unitized mount integrally holding both said punch and said die and being removable from the turret as a single unit.

Claim 10

The ironworker of claim 5, including a unitized mount integrally holding both said punch and said die and being removable from the turret as a single unit.

Claim 11

The ironworker of claim 1, said means for locating the structural member along said first axis including means for moving the structural member supporting means along said first axis.
