Abstract
Abstract The device includes a pile advancing rollerway, the rollers of which are mounted so that the ends thereof are free and spaces are left intermediate of these free ends. Levers are mounted radially on shafts and arranged in opposition to one another so as to form opposing pairs of said levers defining a pile assembling zone. These levers have their arms of an overall length approximating the spacing between these shafts and being offset relative to one another, so that on rotation of these shafts the arms of these levers are brought together and overlap to support a pile in the assembling zone. The device further includes means for spreading these levers, with said shafts being stationary, to provide for delivering of collected bundle from the collecting zone in the same plane in which the piles are advanced thereinto. A compressing plate compresses a bundle being collected. The disclosed structure provides for collecting piles of any printed matter into bundles, prevents running of the levers on the same shafts onto one another and enables to effect compressing of a bundle directly in the course of its collecting.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
351 words
A device for collecting piles of printed matter into bundles, comprising, in combination: a rollerway adapted to advance piles to be collected into bundles, rollers of said rollerway mounted so that the ends thereof are free and spaces are left intermediate of said free ends of adjacent ones of said rollers; shafts mounted longitudinally of said rollerway at both sides thereof adjacent to said free ends of said rollers, said shafts being adapted for intermittent synchronous rotation in opposite directions; levers mounted radially on said shafts and arranged thereon in opposition to one another forming opposing pairs of said levers defining a bundle collecting zone, said levers having arcuately bent portions of a predetermined radius and adapted to support a pile and to lift it on synchronous rotation of said shafts; said levers of each said opposing pair having their arms of a length maximally approximating the spacing between saId shafts and being offset relative to each other, so that when each pair of said opposing pairs of levers are positioned in said collecting zone said pile-supporting portions thereof come together and overlap, said levers, with said shafts being driven through said rotation, being adapted to cooperate with the piles in said collecting zone so that a pair of said arms positioned under a pile lying on said rollerway, which has been advanced into said collecting zone, passes through said spaces intermediate of the respective ones of said rollers, rise above said rollers and take the pile upon themselves, supporting the pile across the bottom plane thereof by said pile-supporting portions of said levers, while another pair of said pairs of said arms, positioned above said pile and supporting thereon the piles that have been already collected, are brought apart by further rotation of said shafts, lowering said previously collected piles onto said pile that is being lifted thereunder, whereby all said piles marry, forming a bundle; means for spreading said levers while said shafts remain stationary and providing for delivery of the collected bundle from said collecting zone in the plane in which piles are advanced into said collecting zone.
Claim 2
Independent Claim
351 words
A device for collecting piles of printed matter into bundles, comprising, in combination: a rollerway adapted to advance piles to be collected into bundles, rollers of said rollerway mounted so that the ends thereof are free and spaces are left intermediate of said free ends of adjacent ones of said rollers; shafts mounted longitudinally of said rollerway at both sides thereof adjacent to said free ends of said rollers, said shafts being adapted for intermittent synchronous rotation in opposite directions; levers mounted radially on said shafts and arranged thereon in opposition to one another forming opposing pairs of said levers defining a bundle collecting zone, said levers having arcuately bent portions of a predetermined radius and adapted to support a pile and to lift it on synchronous rotation of said shafts; said levers of each said opposing pair having their arms of a length maximally approximating the spacing between saId shafts and being offset relative to each other, so that when each pair of said opposing pairs of levers are positioned in said collecting zone said pile-supporting portions thereof come together and overlap, said levers, with said shafts being driven through said rotation, being adapted to cooperate with the piles in said collecting zone so that a pair of said arms positioned under a pile lying on said rollerway, which has been advanced into said collecting zone, passes through said spaces intermediate of the respective ones of said rollers, rise above said rollers and take the pile upon themselves, supporting the pile across the bottom plane thereof by said pile-supporting portions of said levers, while another pair of said pairs of said arms, positioned above said pile and supporting thereon the piles that have been already collected, are brought apart by further rotation of said shafts, lowering said previously collected piles onto said pile that is being lifted thereunder, whereby all said piles marry, forming a bundle; means for spreading said levers while said shafts remain stationary and providing for delivery of the collected bundle from said collecting zone in the plane in which piles are advanced into said collecting zone.
Claim 3
Dependent Claim
140 words
A device as claimed in claim 1, wherein said shafts have journals and recesses in the cylindrical surface thereof; and further including spindles having said levers rigidly mounted thereon and rotatably received in said recesses, whereby said levers can be spread by said lever spreading means; flanges mounted on said journals of said shafts; said spindles being journalled in said flanges; abutment means mounted on said cylindrical surface of each said shaft; spring means having one end thereof connected to said abutment means and having the other end thereof connected to the respective one of said levers, said spring means being adapted to bias said levers toward said abutment means, whereby there is prevented running of said levers of each one of said shafts onto one another as said shaft is rotated jointly with said levers in a predetermined direction.
Claim 4
Dependent Claim
108 words
A device as claimed in claim 1, further including air cylinders associated with plunger rods, the cylinders arranged outside said collecting zone; a compressing plate rigidly mounted on said plunger rods and arranged above said pile-supporting portions of said levers at a minimal spacing therefrom; said cylinders communicating with one another and with ambient air via check valve means, whereby said plunger rods together with said compressing plate can be vertically displaced under the section of the pile being collected; stop means associated with said air cylinders for limiting the stroke of the respective ones of said plunger rods of said air cylinders and provide said minimal spacing.
Claim 5
Dependent Claim
18 words
A device as claimed in claim 3, wherein said stop means includes the bottoms of said air cylinders.
