Abstract

Abstract An automatic inking system in a twin cylinder stencil duplicator including a movable ink stand having a disposable sealed ink container mounted thereon and an indexing mechanism operatively connected to the stand for effecting step-by-step movement of the ink container against its cover which acts as a piston. The indexing mechanism is actuated in response to a predetermined and preset number of revolutions of the main shaft of the machine thereby adjusting the inking rate in accordance with paper type and degree of coverage required.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 210 words
An automatic inking mechanism for a prinTing machine including a rotatable main shaft comprising a movable ink stand, an ink container mounted on said stand adapted to contain a supply of ink and including a cover, an indexing mechanism operatively connected to said stand for effecting stepwise relative movement of said container and cover to dispense ink from said container in discrete amounts and actuating mechanisms including motion transfer means operatively connected to said indexing mechanism and operable in response to each of a series of revolutions of said main shaft for accumulating a series of incremental rotary motions and after said series of incremental rotary motions have been accumulated, transferring an indexing stroke to said indexing mechanism to effect ink dispensation, said motion transfer means including a one-way clutch having a driving raceway member, a driven raceway member and clutch rollers interposed therebetween, and said actuating mechanism further including motion input means actuated in response to each revolution of said main shaft and connected to said driving raceway member for imparting incremental rotary motion thereto and motion output means coupled to said driven raceway member and to said indexing mechanism for providing said indexing stroke after transfer to said one way clutch of said series of incremental rotary motions.
Claim 2
Dependent Claim 210 words
An automatic inking mechanism for a prinTing machine including a rotatable main shaft comprising a movable ink stand, an ink container mounted on said stand adapted to contain a supply of ink and including a cover, an indexing mechanism operatively connected to said stand for effecting stepwise relative movement of said container and cover to dispense ink from said container in discrete amounts and actuating mechanisms including motion transfer means operatively connected to said indexing mechanism and operable in response to each of a series of revolutions of said main shaft for accumulating a series of incremental rotary motions and after said series of incremental rotary motions have been accumulated, transferring an indexing stroke to said indexing mechanism to effect ink dispensation, said motion transfer means including a one-way clutch having a driving raceway member, a driven raceway member and clutch rollers interposed therebetween, and said actuating mechanism further including motion input means actuated in response to each revolution of said main shaft and connected to said driving raceway member for imparting incremental rotary motion thereto and motion output means coupled to said driven raceway member and to said indexing mechanism for providing said indexing stroke after transfer to said one way clutch of said series of incremental rotary motions.
Claim 3
Dependent Claim 41 words
An automatic inking mechanism according to claim 1 wherein said motion transfer means further includes an anti-backlash mechanism operatively connected to said one-way clutch and arranged to preclude rotation in a direction opposite to the direction of said incremental rotary motion.
Claim 4
Dependent Claim 37 words
An automatic inking mechanism according to claim 2 wherein said anti-backlash mechanism includes a fixed holding raceway member surrounding said driven raceway member and clutch rollers interposed between said holding raceway member and said driven raceway member.
Claim 5
Dependent Claim 89 words
An automatic inking mechanism according to claim 1 wherein said actuating mechanisms includes an actuating cam on said main shaft, a follower adapted to engage said actuating cam, motion input means actuated in response to movement of said follower and operatively connected to said motion transfer means and means for adjusting said motion input means to initially position said follower relative to said cam to vary the amount of motion imparted to said motion transfer accumulating means from said cam and follower during each revolution of said main shaft.
Claim 6
Dependent Claim 56 words
An automatic inking mechanism according to claim 1 further including manual actuating means and means including a lost-motion coupling for imparting indexing strokes to said indexing mechanism in response to operation of said manual actuating means, said lost-motion coupling serving to decouple said manual actuating means from said indexing mechanism during operation of said actuating mechanisms.
