Abstract
Abstract A printing wheel or cylinder is formed by a plurality of discs stacked one over another with resilient spacers between them to provide spaces at the outer edges to receive the backing ribs of printing type. The discs are squeezed together to securely grasp the backing ribs and are loosened to remove or replace the printing type.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
85 words
A magazine for holding printing type on a cylindrical coder, comprising: a. a plurality of coaxially stacked equal diameter discs having spaces at their outer edges between adjacent discs for receiving the backing ribs of a print type; b. means located radially inward between adjacent discs for yieldably urging the discs apart axially; and c. means for axially releasably compacting the discs together to compress said yieldable means whereby the discs securely grasp the inserted type backing ribs at the outer edges of the discs.
Claim 2
Dependent Claim
85 words
A magazine for holding printing type on a cylindrical coder, comprising: a. a plurality of coaxially stacked equal diameter discs having spaces at their outer edges between adjacent discs for receiving the backing ribs of a print type; b. means located radially inward between adjacent discs for yieldably urging the discs apart axially; and c. means for axially releasably compacting the discs together to compress said yieldable means whereby the discs securely grasp the inserted type backing ribs at the outer edges of the discs.
Claim 3
Dependent Claim
15 words
The coder magazine as described in claim 1 wherein said yieldable means comprises resilient spacers.
Claim 4
Dependent Claim
26 words
The coder magazine as described in claim 2 wherein said resilient spacers comprise resilient "O" rings resting in grooves on a flat surface of the discs.
Claim 5
Dependent Claim
33 words
The coder magazine as described in claim 1 wherein said discs are annular and are movably mounted on a coaxial rod, said rod including means attached thereto for compacting the discs together axially.
Claim 6
Dependent Claim
98 words
A coder print wheel assembly comprising, in combination: a. a plurality of equal diameter coaxially stacked discs having spaces at the outer edges between adjacent discs for receiving the backing ribs of a print member; b. means located radially inward between adjacent discs for yieldably urging the discs apart axially; c. print type having backing ribs inserted in the space between at least two adjacent discs; and d. means for releasably compacting the discs together axially to compress said yieldable means whereby the discs securely grasp the print type backing ribs at the outer edges of the discs.
Claim 7
Dependent Claim
98 words
A coder print wheel assembly comprising, in combination: a. a plurality of equal diameter coaxially stacked discs having spaces at the outer edges between adjacent discs for receiving the backing ribs of a print member; b. means located radially inward between adjacent discs for yieldably urging the discs apart axially; c. print type having backing ribs inserted in the space between at least two adjacent discs; and d. means for releasably compacting the discs together axially to compress said yieldable means whereby the discs securely grasp the print type backing ribs at the outer edges of the discs.
Claim 8
Dependent Claim
14 words
The invention as in claim 5 wherein the print type backing ribs are resilient.
