Device for mounting interchangeable type

A device for mounting interchangeable type comprising:

• a. a backing member;
• b. a body portion upon which said backing member is mounted;
• c. a pair of spaced, resilient retainer members disposed on said backing member, each retainer member having a neck portion and a head portion, said head portion defining a shoulder between said neck and head portions;
• d. an elongated band having a pair of openings therein, said openings being spaced the same distance as said resilient retainer members to receive the head portions of said resilient retainer members with one side of said band in contact with said shoulder, said elongated band being thin relative to its width, the ratio of the width of said band to the thickness thereof being at least 5:1;
• e. a base disposed between said backing member and each of said retainer members, each base protruding from said backing member so as to contact said band on the side of said band opposite to the side that contacts said shoulder;
• f. a plurality of printing members, each printing member having a character formed thereon and each having a slot through which said band may be passed, each printing member having a rear side disposed opposite said character, the distance between said rear side of each printing member and a rearwardmost side of each slot being approximately equal to the distance said base protrudes from said backing member.
