Work-supporting means and type-bar-setting mechanism in hot-stamping machines

Claim 2

A type-setting mechanism for a stamping machine or the like, comprising: a framework, a plurality of elongated bars mounted for longitudinal movement on said framework, each of said bars having a rack gear and a plurality of impression surfaces spaced aLong at least a portion of the length thereof; means associated with said bars for moving said bars to position a selected one of said impression surfaces of each bar at a printing position of said framework, said means for moving said bars comprising individual pinions operatively coupled with the rack gear of each bar; telescoping sleeves coupled to each of said pinions, said sleeves being individually rotatable and being at different lengths whereby access is provided to each sleeve; indicating means coupled to said bars to indicate the impression surface selected; and means for moving the work to be printed into impression transfer relationship with said impression surfaces of said bars, said means for moving the work comprising a piston and a block mounted on said piston, said block having at least one opening therein for passing said work through said block, movement of said piston causing said block to carry said work into impression transfer relationship with said impression surfaces of said bars.

Claim 3

The apparatus of claim 1 wherein means are provided for heating said selected impression surfaces.

Claim 4

The apparatus of claim 2 wherein a printing foil is interposed between said work and said impression surfaces.

Claim 5

The apparatus of claim 1 wherein said indicating means comprise indicia-bearing surfaces spaced along another portion of the length of said bar, and further comprising means for viewing only a single indicia-bearing surface of each bar, the indicia borne by each surface corresponding to the impression borne by a respective impression surface.

Claim 6

The apparatus of claim 1 wherein said indicating means comprise a dial positioned on each sleeve, said dials having indicia-bearing surfaces spaced around the circumference thereof, and further comprising means for viewing only a single indicia-bearing surface of each dial, the indicia borne by each surface corresponding to the impression borne by a respective impression surface.

Claim 7

In a stamping machine of the type having a framework which includes a reciprocating stamping head, wherein the improvement comprises: a type-setting mechanism having a plurality of elongated bars mounted for longitudinal movement on said framework, each of said bars having a plurality of impression surfaces spaced along at least a portion of the length thereof; means associated with said bars for moving said bars to position a selected one of said impression surfaces of each bar at a stamping position opposite the stamping head; and means for moving the work to be stamped into impression transfer relationship with said selected impression surfaces of said bars for stamping, said moving means carrying the work to be stamped in a position between an anvil member on the stamping head and said selected impression surfaces, the reciprocating stamping head including a pneumatic cylinder and a piston, a block mounted on said piston defining the anvil member and said means for moving the work comprising said piston and said block, said block having at least one opening therein for passing said work through said block whereby the movement of said piston causes said block to carry said work into impression transfer relationship with said selected impression surfaces.

Claim 8

In a stamping machine of the type having a framework which includes a reciprocating stamping head, wherein the improvement comprises: a type-setting mechanism having a plurality of elongated bars mounted for longitudinal movement on said framework, each of said bars having a plurality of impression surfaces spaced along at least a portion of the length thereof; means associated with said bars for moving said bars to position a selected one of said impression surfaces of each bar at a stamping position opposite the stamping head; and means for moving the work to be stamped into impression transfer relationship with said selected impression surfaces of said bars for stamping, said moving means carrying the work to be stamped in a position between an anvil member on the stamping head and said selected impression surfaces, the reciprocating stamping head including a pneumatic cylinder and a piston, a block mounted on said piston defining the anvil member and said means for moving the work comprising said piston and said block, said block having at least one opening therein for passing said work through said block whereby the movement of said piston causes said block to carry said work into impression transfer relationship with said selected impression surfaces.

Claim 9

The apparatus of claim 6 wherein means are provided for heating said selected impression surfaces.

Claim 10

The apparatus of claim 7 wherein a printing foil is interposed between said work and said impression surfaces.
