Abstract
Abstract The characters on the periphery of a rotatable marking wheel are selectively rotated into marking position by a remotely controlled actuating mechanism. The marking wheel has a ratchet portion with a ratchet tooth for each character. The actuating mechanism includes a reciprocating slide with an actuating pawl pivotally connected thereto. For each forward stroke of the slide the actuating pawl engages a tooth and rotates the marking wheel and moves the adjacent character into marking position. A depending finger on the slide also moves into overlying relation with the adjacent tooth to prevent the wheel from rotating through too large an angle to move the adjacent character beyond the marking position. A centering and locking pawl is engaged by the slide on the reverse stroke and moved into engagement with another tooth on the ratchet to center the character in the marking position and maintain the wheel in that position.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
249 words
Apparatus for rotating a marking wheel on a marking device comprising, a marking head housing, a wheel rotatably mounted on said housing and having a plurality of raised portions with marking characters on the periphery thereof, said wheel having a ratchet portion with a plurality of teeth extending radially therefrom, said ratchet portion having the same number of teeth as said wheel peripheral raised portions, an actuating slide mounted in said housing for reciprocal movement therein, said actuating slide positioned in overlying relation with said wheel ratchet portion, sAid housing having a front stop portion and a rear stop portion for said actuating slide, an actuating pawl connected to said slide and operable upon movement of said slide in one direction to engage a tooth of said ratchet portion and rotate said wheel to advance the next adjacent character into marking position, a locking pawl pivotally connected to said housing and having pawl portion operable to engage a tooth of said ratchet portion and limit the rotation of said ratchet and said wheel, said slide having a shoulder portion movable into abutting relation with a portion of said locking pawl to maintain said locking pawl in engagement with a tooth of said ratchet portion, said slide having a depending finger portion adjacent said actuating pawl, and said depending finger portion operable upon movement of said slide to move into overlying relation with a ratchet tooth to prevent rotation of said ratchet and said wheel beyond said next adjacent character.
Claim 2
Dependent Claim
249 words
Apparatus for rotating a marking wheel on a marking device comprising, a marking head housing, a wheel rotatably mounted on said housing and having a plurality of raised portions with marking characters on the periphery thereof, said wheel having a ratchet portion with a plurality of teeth extending radially therefrom, said ratchet portion having the same number of teeth as said wheel peripheral raised portions, an actuating slide mounted in said housing for reciprocal movement therein, said actuating slide positioned in overlying relation with said wheel ratchet portion, sAid housing having a front stop portion and a rear stop portion for said actuating slide, an actuating pawl connected to said slide and operable upon movement of said slide in one direction to engage a tooth of said ratchet portion and rotate said wheel to advance the next adjacent character into marking position, a locking pawl pivotally connected to said housing and having pawl portion operable to engage a tooth of said ratchet portion and limit the rotation of said ratchet and said wheel, said slide having a shoulder portion movable into abutting relation with a portion of said locking pawl to maintain said locking pawl in engagement with a tooth of said ratchet portion, said slide having a depending finger portion adjacent said actuating pawl, and said depending finger portion operable upon movement of said slide to move into overlying relation with a ratchet tooth to prevent rotation of said ratchet and said wheel beyond said next adjacent character.
Claim 3
Dependent Claim
27 words
Apparatus for rotating a marking wheel on a marking device as set forth in claim 1 which includes, cable means to reciprocate said slide in said housing.
Claim 4
Dependent Claim
109 words
Apparatus for rotating a marking wheel on a marking device as set forth in claim 2 in which, said slide includes an upstanding front end portion with a longitudinal passageway therethrough, said cable having a cylindrical jacket positioned thereon adjacent a threaded end portion, a first bolt member threadedly positioned on said cable threaded end portion with said cable end portion extending through said longitudinal passageway in said slide member, a second bolt member securing said cable to said slide upstanding end portion, a stop member abutting said first bolt member and limiting rotation of said first bolt member to thereby maintain said cable secured to said actuating slide.
