Abstract
Abstract Number-printing apparatus arranged in tandem to off-set lithographic printing apparatus is disclosed. The number-printing apparatus is capable of end-wise withdrawal from the printing zone, practically inaccessible to the press operator, for the convenient, rapid resetting of the numbering mechanism. The number-printing apparatus may be singly employed or such may be employed in a paired set so that, when one such apparatus is in the printing zone and operating to print numbers the other is disposed outside of the machine and readily available for resetting by the press operator.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
210 words
Printing apparatus, comprising: an opposed pair of upright supports; rotary inking and impression means mounted between said supports; a printer shaft located substantially inaccessibly adjacent said inking and impression means, said shaft carrying number printing means to travel in a circular path closely tangential with the inking and impression means; a first of said upright supports having an opening through which one end of said printer shaft extends, said opening being of a size to permit said shaft and the number printing means to be Transported outward therethrough; an elongated transport bar slidably mounted in said upright supports parallel to said printer shaft; link means adjacent said first upright support joining common ends of said transport bar and said printer shaft; said printer shaft being rotarily mounted at its outer end to said link means; said transport bar being of such length as to permit the withdrawal of said printer shaft through said opening to afford ready access to said number printing means from outside said first support; a rotatable drive member journalled in the second of said upright supports adjacent the inner end of said printer shaft; telescopic coupling means between said drive member and the inner end of said printer shaft; and means to rotate said drive member.
Claim 2
Dependent Claim
210 words
Printing apparatus, comprising: an opposed pair of upright supports; rotary inking and impression means mounted between said supports; a printer shaft located substantially inaccessibly adjacent said inking and impression means, said shaft carrying number printing means to travel in a circular path closely tangential with the inking and impression means; a first of said upright supports having an opening through which one end of said printer shaft extends, said opening being of a size to permit said shaft and the number printing means to be Transported outward therethrough; an elongated transport bar slidably mounted in said upright supports parallel to said printer shaft; link means adjacent said first upright support joining common ends of said transport bar and said printer shaft; said printer shaft being rotarily mounted at its outer end to said link means; said transport bar being of such length as to permit the withdrawal of said printer shaft through said opening to afford ready access to said number printing means from outside said first support; a rotatable drive member journalled in the second of said upright supports adjacent the inner end of said printer shaft; telescopic coupling means between said drive member and the inner end of said printer shaft; and means to rotate said drive member.
Claim 3
Dependent Claim
57 words
The apparatus according to claim 1 in which there is link means extending from said transport bar in opposite directions and joining said transport bar with one of a pair of printer shafts, and said transport bar is revolvable when withdrawn to permit one or the other of said printer shafts to be aligned with said opening.
Claim 4
Dependent Claim
43 words
The apparatus of claim 1 in which said telescopic coupling means comprises a tapered pin and lug on said rotatable drive member and the inner end of said shaft has a socket to receive said pin and is shaped to engage said lug.
Claim 5
Dependent Claim
33 words
The apparatus of claim 1 in which there is included clamp means mounted on said first support and operable to force said printer shaft toward said telescopic coupling means at its other end.
Claim 6
Dependent Claim
18 words
The apparatus of claim 4 in which said clamp means is of the type employing a toggle action.
Claim 7
Dependent Claim
29 words
The apparatus of claim 4 in which there is pin-and-socket means between said link means and said first support operable to fixedly locate the axis of said printer shaft.
Claim 8
Dependent Claim
45 words
The apparatus of claim 6 in which there is wedge means associated with said link means operable to initiate longitudinal movement of said printer shaft, and force-applying means is associated with said clamp means to activate said wedge means upon release of said clamp means.
