Abstract
Abstract An inserter is adapted to insert successive enclosures from a stack carried by an enclosure feeder assembly into envelopes carried by an envelope feeder assembly. Each feeder assembly includes a sloped tray and a pair of side guides which engage the ends of the stack of materials being fed. Both side guides are adjusted by releasing a tab adjacent one of the guides and sliding the guide. An endless belt mounted beneath the tray assures symmetrical displacement of both guides relative to the center of the tray. A feed wheel is carried along a drive shaft which extends transversely above the tray. The hub of the feed wheel includes a one way clutch which permits adjustment of the feed wheel position. A separator stone projecting from beneath the tray in staggered registration with the feed wheel includes a stone shield. Both the stone and the stone shield are adjustable through control knobs accessible at the front of the inserter. One of the enclosure inserters includes an adjustable mount for spring biased skis which depend from the underside of its tray and engage enclosures which are being transported from a further feeder assembly.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
182 words
A feeder assembly for selectively feeding successive sheet material from a stack, the feeder assembly comprising a tray for carrying the stack of sheet materials, means forming a pair of guides for engaging the stack, means adjustably securing each guide relative to the tray, said securing means including means for adjusting the guides relative to one another for parallelism, the securing means including a pair of carrier means, each guide being secured to a respective carrier means, and means for simultaneously moving both carrier means for symmetrical placement of the guides relative to the tray, means for retaining the guides in an adjusted position, the retaining means including friction means extending from one carrier means and means biasing the friction means toward the underside of the tray, means mounting the tray in a sloped plane and guide biasing means for urging one end of each guide in a direction perpendicular from the plane of the tray, the guide biasing means comprising shoe means engaging the underside of each guide adjacent the upper end of the tray, whereby feeder assembly set-up is simplified.
Claim 2
Dependent Claim
182 words
A feeder assembly for selectively feeding successive sheet material from a stack, the feeder assembly comprising a tray for carrying the stack of sheet materials, means forming a pair of guides for engaging the stack, means adjustably securing each guide relative to the tray, said securing means including means for adjusting the guides relative to one another for parallelism, the securing means including a pair of carrier means, each guide being secured to a respective carrier means, and means for simultaneously moving both carrier means for symmetrical placement of the guides relative to the tray, means for retaining the guides in an adjusted position, the retaining means including friction means extending from one carrier means and means biasing the friction means toward the underside of the tray, means mounting the tray in a sloped plane and guide biasing means for urging one end of each guide in a direction perpendicular from the plane of the tray, the guide biasing means comprising shoe means engaging the underside of each guide adjacent the upper end of the tray, whereby feeder assembly set-up is simplified.
Claim 3
Dependent Claim
39 words
A feeder assembly constructed in accordance with claim 1 wherein the means for adjusting for parallelism includes mounting means projecting from each guide and means forming slots in the respective carrier means, the mounting means extending through the slots.
Claim 4
Dependent Claim
65 words
A feeder assembly constructed in accordance with claim 1 further including tab means, means pivotally mounting the tab means to one carrier means, the friction means projecting from the tab means, the biasing means engaging the tab means, the tab means being pivotable against the bias of the biasing means and toward the guide carried by the one carrier means to release the friction means.
Claim 5
Dependent Claim
32 words
A feeder assembly constructed in accordance with claim 1 wherein the friction means comprises a grating, the retaining means further including means forming a mating grating on the underside of the tray.
Claim 6
Dependent Claim
89 words
A feeder assembly constructed in accordance with claim 1, the securing means further including means mounting each carrier means for translational movement relative to the tray, the means for simultaneously moving both carrier means including means projecting from each carrier means, direction reversal means mounted beneath the tray, the projecting means of each carrier means engaging the direction reversal means, the projecting means of one carrier means driving the direction reversal means, the direction reversal means driving the projecting means of the other carrier means in an opposite direction.
Claim 7
Dependent Claim
33 words
A feeder assembly constructed in accordance with claim 5 wherein the direction reversal means comprises an endless belt mounted in a configuration including two substantially parallel spans, the projecting means engaging opposite spans.
