Abstract
An elongated base block of hard metal material has a flat upper surface to act as an anvil for a key resting on such surface. A narrow key-clamping rail extends lengthwise of the anvil and thumbscrews at its opposite ends may be turned to clamp the key. A die for debossing indicia in the key can be positioned vertically by holding it against a vertical surface of the rail. Alternatively, a die can be positioned in an upright guide slot of a carriage or saddle movable along the rail and sized to closely receive the die. By maintaining the die with its length precisely perpendicular to the upper surface of the anvil and, consequently, the key, a uniform impression in the key is assured when the die is struck.
Claims14
For use with a key and an elongated die for debossing indicia in the key, a key stamp comprising an anvil having a surface for engaging against the key, means for maintaining the key substantially stationary relative to said anvil by clamping the key to said anvil, said clamping means including an elongated rail and means for moving said rail toward and away from said anvil, and a carriage mounted for movement relative to said anvil, said carriage having a guide slot for closely receiving the die to position it with its length at a desired angle relative to the key, said carriage being mounted for movement along said rail.
For use with a key and an elongated die for debossing indicia in the key, a key stamp comprising an elongated base block having a flat upper surface forming an anvil, an elongated rail of a width much narrower than the width of said elongated base block, means mounting said rail over said base block for movement toward and away from said upper surface thereof to clamp and release a key positioned between said rail and said block, a saddle slidable along said rail and having an upright guide groove offset from said rail but aligned with said upper surface of said base block and sized to receive the die closely and position it with its length substantially perpendicular to said upper surface of said base block.
For use with a key and an elongated die for debossing indicia in the key, a key stamp comprising an anvil having a surface for engaging against the key, means for maintaining the key substantially stationary relative to said anvil, a horizontally elongated rail extending alongside said anvil, and a saddle having a groove of a depth less than the upright dimension of said rail and opening at the bottom thereof for closely receiving the rail and permitting free sliding movement of said saddle lengthwise along said rail, said saddle having a guide slot for closely receiving the die to position it with its length at a desired angle relative to the key such that said saddle is detachable from said rail by manual translation away from said rail and said anvil.
For use with a key and an elongated die for debossing indicia in the key, a key stamp comprising an anvil having a surface for engaging against the key, means for maintaining the key substantially stationary relative to said anvil, an elongated rail extending alongside said anvil, and a saddle having a groove opening at the exterior thereof for closely receiving the rail and permitting free sliding movement of said saddle lengthwise along said rail, said saddle having two separate guide slots for closely receiving dies of different cross-sectional size and positioned at opposite sides of said rail, respectively, when said saddle is mounted on said rail for positioning a selected die with its length at a desired angle relative to the key.
