Abstract
Abstract A device for mounting interchangeable type including a pair of spaced, resilient retainer members disposed on a backing member. Each retainer member has a neck portion and a head portion. One or more thin, elongated, flat bands, each having a pair of spaced openings therein, may slidably receive a plurality of interchangeable printing members thereon. The head portions of the retainer members are passed through the openings in each band to retain each band on the backing member.

Total Claims: 22
Claim 1
Independent Claim
234 words
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.
Claim 2
Independent Claim

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.
Claim 3
Dependent Claim
42 words
A device as defined in claim 1 wherein said band, at least in the region of said openings, is rigid in relation to the resilient retainer members, whereby only said retainer members are deformed when passed through said openings in said band.
Claim 4
Dependent Claim
17 words
A device as defined in claim 1 wherein said retainer members are integral with said backing member.
Claim 5
Dependent Claim
31 words
A device as defined in claim 1 wherein each base is of such area as to contact the entire width of said band in the region of each of said openings.
Claim 6
Dependent Claim
20 words
A device as defined in claim 1 wherein each base has a width greater that the width of said band.
Claim 7
Dependent Claim
20 words
A device as defined in claim 1 wherein said backing member, said retainer members and said bases are integrally formed.
Claim 8
Dependent Claim
56 words
A device as defined in claim 1 wherein the head portion of each retainer member includes a frusto-conical portion adjacent said neck and a convex portion forming the free end of each retainer member, said frusto-conical portion defining an annular shoulder between said neck and said head portion to retain said band on said backing member.
Claim 9
Dependent Claim
67 words
A device as defined in claim 1: a. wherein said head portion is elongated in a direction perpendicular to the axis of said neck; b. wherein said openings in said band are elongated; c. each head portion being rotatable into alignment with one of said openings for passage therethrough and then rotatable out of alignment with said one opening to secure said band on said backing member.
Claim 10
Dependent Claim
44 words
A device as defined in claim 8 wherein each retainer member is movable between a relaxed position and a deformed position, each head portion being in misalignment with one of said slots in said relaxed position and in alignment therewith in said deformed position.
Claim 11
Dependent Claim
39 words
A device as defined in claim 1, wherein each printing member is resilient and said slot means passes therethrough, said band extending through each slot means in tightly fitting, resilient relationship to secure said printing members on said band.
Claim 12
Dependent Claim
25 words
A device as defined in claim 10 wherein said rear side of each printing member has a rough texture for grippingly engaging said backing member.
Claim 13
Dependent Claim
17 words
A device as defined in claim 1 wherein said backing member comprises a plurality of spaced sections.
Claim 14
Dependent Claim
25 words
A device as defined in claim 1 wherein said body portion includes a handle thereon, whereby said device may be used as a hand stamp.
Claim 15
Dependent Claim
29 words
A device as defined in claim 1 wherein said body portion comprises a rotatable drum having a curved face thereon, said backing member being mounted on said curved face.
Claim 16
Dependent Claim
28 words
A device as defined in claim 14 wherein said band is disposed on said drum in parallel relationship with respect to the axis of rotation of said drum.
Claim 17
Dependent Claim
16 words
A device as defined in claim 14 wherein said band is disposed circumferentially on said drum.
Claim 18
Dependent Claim
29 words
A device as defined in claim 16 wherein said band has a preformed curvature along its length, said preformed curvature corresponding approximately to the curvature of said drum face.
Claim 19
Dependent Claim
64 words
A device as defined in claim 14 wherein said drum includes a pair of circumferentially disposed, protruding rim members thereon, each rim member being located adjacent one end of said drum, said rim members protruding radially from said curved face a distance more than the distance which said retainer members protrude from said surface but less than the distance which said characters protrude therefrom.
Claim 20
Dependent Claim
23 words
A device as defined in claim 1 wherein said ratio of the width of said band to the thickness thereof is approximately 16:1.
