Abstract

Abstract A plurality of wheels are rotated into printing position by means of individual circular adjusting wheels. The adjusting wheels are arranged along a mounting shaft and include an internal lug-like projection extending radially towards the shaft. A stepping rack is positioned to extend transversely through an open portion in each adjusting wheel. Entrainment devices are mounted on pivotal slide bars and are moved progressively by the rack from alignment with one adjusting wheel to the next in sequential order. Actuation of a press key corresponding to the figure to be printed positions a stop pin by means of a control cable. A solenoid actuates the setting mechanism which rotates the pivotal slides. Consequently, the entrainment devices rotate the projection on the adjusting wheel into alignment with the stop pin to properly position the respective type wheel. Correction of a type wheel position can be made by manually positioning the entrainment devices on the slide bars and reactivating the proper press key. A plurality of line impressions can be made by duplicating the adjustable type wheel apparatus. One set of press keys is sufficient for a plurality of type lines by repositioning a plurality of corresponding cable sets below the fixedly positioned press keys.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 94 words
A type setting apparatus for use within a printing unit having a plurality of printing wheels comprising: a. a plurality of adjusting wheels, b. each said adjusting wheel including means to individually position a printing wheel of said printing unit when the adjusting wheel is rotated, c. means to set each adjusting wheel at a preselected rotational position, d. means for sequentially positioning the setting means adjacent each adjusting wheel, and e. means for actuating said setting means to rotate the selected adjusting wheel to said preselected rotational position thereby positioning each printing wheel.
Claim 2
Dependent Claim 94 words
A type setting apparatus for use within a printing unit having a plurality of printing wheels comprising: a. a plurality of adjusting wheels, b. each said adjusting wheel including means to individually position a printing wheel of said printing unit when the adjusting wheel is rotated, c. means to set each adjusting wheel at a preselected rotational position, d. means for sequentially positioning the setting means adjacent each adjusting wheel, and e. means for actuating said setting means to rotate the selected adjusting wheel to said preselected rotational position thereby positioning each printing wheel.
Claim 3
Dependent Claim 40 words
An apparatus as defined in claim 1 wherein said actuating means includes a plurality of selectively extendible stop pins and means for extending the stop pins to establish individual type positions at which each printing wheel is stopped during rotation.
Claim 4
Dependent Claim 59 words
An apparatus as defined in claim 1 wherein said actuating means includes a plurality of stop pins, a set of press keys and means connecting each stop pin to a press key, each stop pin being selectively extendible by a press key connected therewith to establish an individual type position at which each printing wheel is stopped during rotation.
Claim 5
Dependent Claim 15 words
An apparatus as defined in claim 3 wherein said connecting means includes a flexible cable.
Claim 6
Dependent Claim 41 words
An apparatus as defined in claim 1 wherein said actuating means includes a plurality of stop pins, connected with a set of press keys through a set of individual cables which separately interconnect each press key with a corresponding stop pin.
Claim 7
Dependent Claim 87 words
An apparatus as defined in claim 1 wherein said actuating means includes a plurality of stop pins, a set of press keys, means connecting each stop pin to a press key, each press key being electrically connected to a solenoid and an actuating switch for the solenoid, each stop pin being selectively extendible by a press key connected therewith to establish individual type positions at which each printing wheel is stopped during rotation, said actuating switch being closed by depressing a press key to energize the solenoid.
Claim 8
Dependent Claim 156 words
An apparatus as defined in claim 1 wherein said setting means includes a pair of slide bars and entrainment means for slidable movement along said slide bars, said sequential positioning means includes rack means for effecting transverse movement of the entrainment means along said slide bars to a preselected adjusting wheel, said adjusting wheel including means to be entrained by the entrainment means to rotate the adjusting wheel, said slide bar being movably mounted with respect to each other so that the entrainment means can effect rotation of a preselected adjusting wheel to said preselected rotational position, said actuating means includes a plurality of stop pins, a solenoid, means for energizing said solenoid and cam means for movement upon energizing said solenoid, said cam means being operatively associated with the slide bars for effecting movement of the slide bars to activate the entrainment means which abuttingly engages a selectively extended top pin to limit its movement.
Claim 9
Dependent Claim 76 words
An apparatus as defined in claim 1 wherein said setting means includes a pair of slide bars and entrainment means positioned for slidable movement along said slide bars, said adjusting wheels including means to be entrained by the entrainment means to rotate the adjusting wheel, said slide bars being movably mounted with respect to each other to move the entrainment means for rotating each adjusting wheel when the slide bars move with respect to each other.
Claim 10
Dependent Claim 32 words
An apparatus as defined in claim 8 wherein said sequentially positioning means includes rack means connected with said entrainment means for positioning the entrainment means with respect to each particular adjusting wheel.
Claim 11
Dependent Claim 44 words
An apparatus as defined in claim 9 wherein said rack means is manually positionable so as to align the entrainment means with any desired adjusting wheel whereby the position of the aligned wheel can be changed without disturbing the position of the otheR wheels.
Claim 12
Dependent Claim 57 words
An apparatus as defined in claim 1 wherein all of the adjusting wheels are rotatably mounted on a single shaft, each adjusting wheel includes a projecting member which extends radially inwardly toward the center of the wheel, said setting means sequentially positions the projecting member causing rotation of the respective adjusting wheel to a preselected rotational position.
Claim 13
Dependent Claim 103 words
An apparatus as defined in claim 1 wherein said actuating means includes a single set of press keys, more than one set of a plurality of stop pins and more than one set of cables for moving the stop pins to an extended position. one end of each set of cables being registered with a respective set of stop pins, the other end of each said set of cables being fixedly attached to a shiftable mounting plate, means for shifting said mounting plate is provided so that said other end of the cables may be selectively registered with the set of press keys.
