Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
In a printing apparatus, opposed, spaced apart, rigid shaftsupport members, a support shaft extending between said members and being supported at opposite ends by said members, and a plurality of motor and type carrier assemblies each comprising a type carrier rotatably mounted on said shaft, type positioned on the periphery of said carrier for printing characters, a type carrier drive motor having a rotatable power output shaft, motion transmitting means drive connecting said output shaft to said carrier for imparting rotation of said power output shaft to said carrier, and means for removably mounting said motor between said shaft-support members the motors of said assemblies being removably supported independently of each other by their respective mounting means, and the mounting means of said assemblies providing for the removal of the motor in each of said assemblies without requiring the removal of the motors in any of the other of said assemblies.
Claim 2
Dependent Claim
151 words
In a printing apparatus, opposed, spaced apart, rigid shaftsupport members, a support shaft extending between said members and being supported at opposite ends by said members, and a plurality of motor and type carrier assemblies each comprising a type carrier rotatably mounted on said shaft, type positioned on the periphery of said carrier for printing characters, a type carrier drive motor having a rotatable power output shaft, motion transmitting means drive connecting said output shaft to said carrier for imparting rotation of said power output shaft to said carrier, and means for removably mounting said motor between said shaft-support members the motors of said assemblies being removably supported independently of each other by their respective mounting means, and the mounting means of said assemblies providing for the removal of the motor in each of said assemblies without requiring the removal of the motors in any of the other of said assemblies.
Claim 3
Dependent Claim
112 words
The printing apparatus defined in claim 1 wherein said mounting means of each of said assemblies comprises plate means, with each motor having a housing fixed to said plate means, said plate means being formed with an outwardly opening notch along an edge thereof, and each of said assemblies further comprising at least one elongated, threaded member extending through said notch and being fixed at opposites to said shaft-support members, and means threaded on said threaded member and releasibly clamping said plate means on said threaded member, said means threaded on said threaded member being selectively releasible to provide for the removal of said plate means and said motor as a unit.
Claim 4
Dependent Claim
40 words
The printing apparatus defined in claim 2 wherein said means threaded on said threaded members comprises a pair of parts seated against opposite sides of said plate means in the region of said notch to clamp said plate means therebetween.
Claim 5
Dependent Claim
130 words
The printing apparatus defined in claim 3 wherein said motion transmitting means of each of said assemblies comprises first and second power transmitting members respectively coaxially fixed to said carrier and the power output shaft of said motor and a tensionable, endless, flexible member trained over said power transmitting members for drive connecting said second member to said first member, the rotational axes of said carrier and said power output shaft being parallel with each other and with the longitudinal axis of said threaded member, and said plate means being selectively swingable about the longitudinal axis of said threaded member to adjust the tension in said endless member when either or both of said parts are threaded to positions where they are released from clamping engagement with said plate means.
Claim 6
Dependent Claim
42 words
The printing apparatus defined in claim 4 comprising support base means, means releasably mounting said shaft-support members on said base means to provide for the removal of said support members, said shaft, and said assemblies as a unit from said base means.
Claim 7
Dependent Claim
53 words
The printing apparatus defined in claim 1 wherein rotational axes of the motors of said assemblies are parallel with each other and with the longitudinal axis of said support shaft, and wherein said motors are arranged and supported in a stepped spiral path extending partially around the longitudinal axis of said support shaft.
Claim 8
Dependent Claim
29 words
The printing apparatus defined in claim 1 wherein the rotational axis of each power output shaft of said assemblies is parallel with the longitudinal axis of said support shaft.
Claim 9
Dependent Claim
28 words
The printing apparatus defined in claim 1 wherein said motors are arranged and supported along a curved path extending partially around the longitudinal axis of said support shaft.
