US3782277A — Offset press numbering assembly

Claim 1

Independent Claim 304 words

In an offset printing machine of the type having a printing apparatus and a delivery machine associated therewith for normally receiving material acted on by the printing machine and delivering it to a point of deposit, said delivery machine including a drive means operatively associated with said printing machine and a pickup jaw assembly operable to grip material released by the printing machine, the combination therewith of: a first shaft rotatably mounted to said delivery machine, a serial numbering machine mounted on said first shaft for rotation therewith, an elongated carriage pivotally mounted intermediate its length to said delivery machine, a second shaft rotatably mounted on one end of said carriage, an impression roller mounted on said second shaft for rotation therewith, the pivoting of said carriage causing said impression roller to move between an upper and lower position defining the respective printing and out of printing positions of said impression roller relative to said numbering machine, said first and seconds shafts being operatively connected to the drive means on said delivery machine, a releasable latch member on said delivery machine engageable with and normally holding said carriage in a position defining the printing position of said impression roller relative to said numbering machine, paper detection means on said pickup jaw assembly responsive to the presence and absence of gripped material therein, said paper detection means being movable during its travel with said delivery machine to and from different angular positions relative to the presence and absence of in the pickup jaw assembly, and in the absence of such material, said paper detection means being positioned to act against and release said latch member whereby the weight of said impression roller at one end of said carriage causes said carriage to pivot by gravity to place said impression roller in out of printing position.

Claim 2

Dependent Claim 304 words

In an offset printing machine of the type having a printing apparatus and a delivery machine associated therewith for normally receiving material acted on by the printing machine and delivering it to a point of deposit, said delivery machine including a drive means operatively associated with said printing machine and a pickup jaw assembly operable to grip material released by the printing machine, the combination therewith of: a first shaft rotatably mounted to said delivery machine, a serial numbering machine mounted on said first shaft for rotation therewith, an elongated carriage pivotally mounted intermediate its length to said delivery machine, a second shaft rotatably mounted on one end of said carriage, an impression roller mounted on said second shaft for rotation therewith, the pivoting of said carriage causing said impression roller to move between an upper and lower position defining the respective printing and out of printing positions of said impression roller relative to said numbering machine, said first and seconds shafts being operatively connected to the drive means on said delivery machine, a releasable latch member on said delivery machine engageable with and normally holding said carriage in a position defining the printing position of said impression roller relative to said numbering machine, paper detection means on said pickup jaw assembly responsive to the presence and absence of gripped material therein, said paper detection means being movable during its travel with said delivery machine to and from different angular positions relative to the presence and absence of in the pickup jaw assembly, and in the absence of such material, said paper detection means being positioned to act against and release said latch member whereby the weight of said impression roller at one end of said carriage causes said carriage to pivot by gravity to place said impression roller in out of printing position.

Claim 3

Dependent Claim 32 words

A machine as defined in claim 1 including: said latch member being selectively manually operable to effect pivotal movement of said carriage to the out of printing position of said Impression roller.

Claim 4

Dependent Claim 152 words

A machine as defined in claim 1 including: said latch member being spring loaded to yielding maintain its locked position, a trip lever carried by said delivery machine and travelable with the regular components thereof in the receipt and delivery of material from the printing machine, said trip lever being pivotable to first and second positions whereby in said first position it is capable of contacting and releasing said latch member in its line of travel and in said second position it moves free of contact with said latch member, means on said delivery machine responsive to the presence and absence of material released by said printing machine, and said last mentioned means in the absence of material released by said printing machine acting on said lever to move it to said first position and in the presence of such material acting on said lever to move it to its second position.

Claim 5

Dependent Claim 218 words

A machine as defined in claim 1 the combination therewith of: said latch member being spring loaded and engaged with said carriage to normally yieldingly hold it in printing position, a rod slidably arranged in said jaw assembly, a pivotable spring loaded lever carried by said delivery machine and operably connected to said rod for moving it into and out of said jaw assembly, a cam on said delivery machine engagable by said lever in the normal travel of said jaw assembly, the engagement of said lever with said cam causing pivotal movement of the lever from its original position to a second position and corresponding movement of said rod out of the jaw assembly and synchronized with the position of the jaw assembly to receive and grip material from the printing machine, said lever moving out of engagement with said cam with movement of said jaw assembly out of material receiving position relative to said printing machine so that it is capable of pivotal movement to its original position to effect movement of said rod into said jaw assembly in the absence of material in the jaw assembly, and in the absence of such material, said lever being returned to its original position to engage and release said latch to move said carriage out of printing position.

Claim 6

Dependent Claim 58 words

A machine as defined in claim 4 including: the release of said latch causing the latched end of said carriage to move downwardly and the opposite end to move upwardly, and said lever after releasing said latch, moving with said jaw assembly to engage the other end of said carriage and effect its return to its latched position.

Claim 7

Dependent Claim 55 words

A machine as defined in claim 4 including: the presence of material in said jaw assembly serving as an obstruction to the movement of said rod into said assembly whereby said lever is held in its second position where it moves free of contact with said latch and said carriage is maintained in printing position.

Claim 8

Dependent Claim 31 words

A machine as defined in claim 4 including: said latch being manually releasable, and a manually operable lock means on said carriage to selectively hold said carriage out of printing position.
