Abstract

A stamper with a metal plate positioned between a platen and a stamp die is disclosed. The metal plate results in an improved imprint by providing better support to the stamp die. The stamper further comprises a removable ink pad and a rotatably reversible platen with cam mechanism. The metal platen plate with it'"'"'s adjoining stamp die face downwards when the stamper is in an imprint position and the metal platen plate with it'"'"'s adjoining stamp die face upwards when the stamper is in a re-inking position.

Claims

1. A stamper comprising:

a. a non-metallic upper housing, slidably biased over a non-metallic lower housing by a spring;

b. said upper housing including parallel vertical rails, that traverse between platen tracks formed by combining an inner section and an outer section of said lower housing;

c. an ink pad located within said lower housing;

d. a single reversible platen rotatably engaging a pair of platen tracks within the inner section of said lower housing, said reversible platen comprising a platen body including a cam;

e. a first side of a rigid metal plate connected with said platen body; and

;

f. a stamp die connected with the opposite side of said metal plate;

g. wherein said metal platen plate and the stamp die face downwards when the stamper is in an imprint position and said metal platen plate and the stamp die face upwards when the stamper is in a re-inking position.

2. A stamper as in claim 1, wherein said stamp die is removably connected with said metal plate by an adhesive.

3. A stamper as in claim 1, wherein said ink pad is a removable ink pad which may be slidably removable from the fully assembled stamper.

4. A stamper as in claim 1, wherein said cam comprises:

a. a cam peg between a first cam indentation and a second cam indentation;

b. wherein said cam rotatably engages a first lower housing peg and a second lower housing peg inducing said platen to rotate within said lower housing.

5. A stamper as in claim 1, further comprising:

a removable top cover snap fitted onto the top of said upper housing.

6. A stamper as in claim 5 wherein said removable top cover is transparent and wherein an advertising insert with various indicia may be placed between the removable top cover and the top of the upper housing.

7. A stamper comprising:

a. a non-metallic upper housing, slidably biased over a non-metallic lower housing by a spring;

b. an ink pad;

c. a single reversible platen rotatably engaging a pair of platen tracks within the inner section of said lower housing, said reversible platen comprising a platen body including a cam;

d. a first side of a rigid metal plate connected with said platen body;

e. a stamp die connected with the opposite side of said metal plate;

f. wherein said metal platen plate with its adjoining stamp die face downwards when the stamper is in an imprint position and said metal platen plate with its adjoining stamp die face upwards when the stamper is in a re-inking position.

8. A spring biased stamper comprising a rigid metal plate connected between a plastic platen and a stamp die.

9. A method of assembling a stamper comprising the steps of:

a. connecting a removable top cover to a top of a non-metallic upper housing;

b. connecting a spring to an inside of said upper housing;

c. connecting an inner section of a non-metallic lower housing to an outer section of said lower housing;

d. inserting a slidably removable ink pad into the lower housing;

e. connecting the lower housing to the upper housing and the spring; and

f. connecting a single platen affixed to a rigid metal plate to holes in parallel vertical rails by way of platen guide pins.
