Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
211 words
In a high-speed serial-type wire printer having a frame, a platen mounted on said frame for backing impresseion-receiving media, a carriage movable transversely of said platen, a print head carried by said carriage with printing wires reciprocable in a plane substantially at right angles to the surface of said platen to effect impressions against said media during transverse movement of the print head by said carriage along a print line on said platen; media thickness compensation means for maintaining said print head a predetermined distance from said media regardless of the thickness of the latter to accommodate media of different thicknesses disposed along said print line, comprising means for mounting said print head on said carriage for movement relative thereto perpendicular to said print line, biasing means for resiliently urging said print head away from said platen, and adjustable stop means engageable by said print head in response to said biasing means, wherein said adjustable stop means comprises a shaft mounted on said frame axially parallel to said platen, and a plurality of individual stop members rotatable on said shaft in a series extending for the length of said platen, and wherein each said stop member comprises a polyhedron presenting a plurality of peripheral faces each differently spaced from said shaft.
Claim 2
Dependent Claim
211 words
In a high-speed serial-type wire printer having a frame, a platen mounted on said frame for backing impresseion-receiving media, a carriage movable transversely of said platen, a print head carried by said carriage with printing wires reciprocable in a plane substantially at right angles to the surface of said platen to effect impressions against said media during transverse movement of the print head by said carriage along a print line on said platen; media thickness compensation means for maintaining said print head a predetermined distance from said media regardless of the thickness of the latter to accommodate media of different thicknesses disposed along said print line, comprising means for mounting said print head on said carriage for movement relative thereto perpendicular to said print line, biasing means for resiliently urging said print head away from said platen, and adjustable stop means engageable by said print head in response to said biasing means, wherein said adjustable stop means comprises a shaft mounted on said frame axially parallel to said platen, and a plurality of individual stop members rotatable on said shaft in a series extending for the length of said platen, and wherein each said stop member comprises a polyhedron presenting a plurality of peripheral faces each differently spaced from said shaft.
Claim 3
Dependent Claim
38 words
In a media thickness compensation means according to claim 1, a roller rotatably mounted on said print head for engagement with said stop member faces, said biasing means urging said roller into engagement with said stop member faces.
Claim 4
Dependent Claim
52 words
In a media thickness compensation means according to claim 2, a rail secured to said frame parallel to said platen, and a pair of secondary rollers mounted on said carriage equidistantly spaced transversely on opposite side, respectively, from said roller and resiliently maintained in engagement with said rail by said biasing means.
Claim 5
Dependent Claim
43 words
In a media thickness compensation means according to claim 1, identifying indicia on said face of each said stop member indicating a particular media thickness with which said print head will be properly positioned when that stop member face is in operative position.
Claim 6
Dependent Claim
44 words
In a media thickness compensation means according to claim 1, wherein each said stop member is manually rotatable to position any selected said face in operative position relative to said print head, detent means for frictionally retaining said stop members in selected operative positions.
Claim 7
Dependent Claim
56 words
A media thickness compensation means according to claim 5, wherein adjacent faces of each said stop member are separated by transverse grooves, and said detent means comprises a spring pawl for each said stop member having one end secured to said frame and a free end engageable in said grooves of the associated said stop member.
Claim 8
Dependent Claim
91 words
In a media thickness compensation means according to claim 6, a normally closed control switch, a bail having legs pivotally mounted on said frame, a transversely extending portion engageable with said free ends of said pawls, and a switch operating portion, and spring means resiliently holding said bail in an inoperative position, whereby rotation of any stop member to any position in which none of its said faces is in operative position will move its associated said pawl to swing said bail against said spring means to open said control switch.
