Abstract
Abstract A marking machine of the type having a powered rotary marking head provided with heated raised indicia brought sequentially and repeatedly into contact with a pigment source and a linearly moving workpiece to be imprinted by the indicia. The device is provided with a rotary drive train which may be geared to the workpiece drive and is equipped with adjustment mechanisms within the train providing for both rotary angle adjustment of the head with respect to the drive input and rotational speed adjustment varying the rate of rotation during each rotation of the head to adjust to different spacing between imprints while maintaining proper imprint speed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
345 words
A rotary head imprint marker comprising a housing, an input shaft to said housing, an output shaft from said housing and being parallel to said input shaft, a rotary marker head affixed to said output shaft exterior of said housing for rotation with the output shaft, and said head carrying type means adapted for marking on selected areas at spaced intervals along a traveling workpiece during the rotations of said head, and comprising: drive train means within said housing between said imput shaft and said output shaft whereby said output shaft is driven by said input shaft, and said drive train means including: first, adjustable means movable longitudinally along said input shaft for advancing or retarding the relative rotary angular position of the output shaft with respect to said input shaft and thereby effecting corresponding advancing or retarding of said type means and determining the longitudinal locations of the selected areas marked by said type means on the traveling workpiece; second, selectively presettable means for selectively varying the speed of said output shaft during a portion of each revolution of said output shaft with respect to the speed of revolution of said input shaft, so that the speed of revolution of said head and type means is coordinated with the speed of the traveling workpiece at each marking of said type means on the areas selected by means of said first, adjustable means; and means for drivingly connecting said first, adjustable means with said second, selectively presettable means; said second, presettable means comprising: means driven by said drivingly connecting means and carried by a movable bracket, said driven means terminating in a first shaft which has a first eccentric drive member affixed thereto, a second shaft, said second shaft being held in fixed rotatable position with respect to said housing and having a second eccentric driven member affixed thereto, a drive connection between said first eccentric drive member and said second eccentric driven member, the position of said first shaft being variable with respect to said second shaft by selective adjustment movement of said bracket.
Claim 2
Dependent Claim
345 words
A rotary head imprint marker comprising a housing, an input shaft to said housing, an output shaft from said housing and being parallel to said input shaft, a rotary marker head affixed to said output shaft exterior of said housing for rotation with the output shaft, and said head carrying type means adapted for marking on selected areas at spaced intervals along a traveling workpiece during the rotations of said head, and comprising: drive train means within said housing between said imput shaft and said output shaft whereby said output shaft is driven by said input shaft, and said drive train means including: first, adjustable means movable longitudinally along said input shaft for advancing or retarding the relative rotary angular position of the output shaft with respect to said input shaft and thereby effecting corresponding advancing or retarding of said type means and determining the longitudinal locations of the selected areas marked by said type means on the traveling workpiece; second, selectively presettable means for selectively varying the speed of said output shaft during a portion of each revolution of said output shaft with respect to the speed of revolution of said input shaft, so that the speed of revolution of said head and type means is coordinated with the speed of the traveling workpiece at each marking of said type means on the areas selected by means of said first, adjustable means; and means for drivingly connecting said first, adjustable means with said second, selectively presettable means; said second, presettable means comprising: means driven by said drivingly connecting means and carried by a movable bracket, said driven means terminating in a first shaft which has a first eccentric drive member affixed thereto, a second shaft, said second shaft being held in fixed rotatable position with respect to said housing and having a second eccentric driven member affixed thereto, a drive connection between said first eccentric drive member and said second eccentric driven member, the position of said first shaft being variable with respect to said second shaft by selective adjustment movement of said bracket.
Claim 3
Dependent Claim
60 words
The device of claim 1 wherein the first, adjustable means comprises a driven helical pinion splined to said input shaft and axially movable therealong which meshes with a helical gear shaft whereby axial movement of the pinion along the input shaft relative to the helical gear shaft will vary the rotation angular position between the input shaft and helical gear.
Claim 4
Dependent Claim
55 words
The device of claim 2 wherein the pinion is movable along said input shaft by the movement of a pinion clevis, the pinion clevis being in threaded engagement with a bolt means extending parallel to said input shaft, said bolt means including a crank means exterior of said housing for rotation of said bolt means.
Claim 5
Dependent Claim
38 words
A rotary head imprint marker according to claim 2, wherein said bracket is pivotally mounted, and said driven means comprises a gear train carried by said bracket and driven by a gear carried by said helical gear shaft.
Claim 6
Dependent Claim
24 words
The device of claim 1 including, adjustment means between the bracket and the housing for controlling pivoting movement of the bracket within the housing.
Claim 7
Dependent Claim
17 words
The device of claim 5 including speed multiplier means between said second shaft and the output shaft.
Claim 8
Dependent Claim
99 words
The device of claim 1 wherein said first, adjustable and said second, presettable means are each provided with adjusting means exterior of said housing for adjusting them from the exterior of the housing, an ink roll rotatably carried by said housing exterior thereof adjacent said rotary marker head in position to be contacted by said type means carried by said rotary marker head, a power drive means between said output shaft and said ink roll, said power drive means driving said ink roll at a rotational speed different than said output shaft, said drive means including a slip drive.
Claim 9
Dependent Claim
53 words
The device of claim 7 including a backup roller means carried by said housing exterior thereof adjacent said marker head on the side of said marker head diammetrically opposed to said ink roll, eccentric means associated with said backup roller effective to move said backup roller towards and away from said marker head.
Claim 10
Dependent Claim
44 words
The device of claim 8 wherein said backup roller is carried on a roller shaft means, said roller shaft means affixed to said housing by bracket means, said bracket means being adjustable to adjust positioning of said backup roller relative to said marker head.
