Abstract
Abstract Apparatus for accumulating arrays of superimposed layers of parallel cigarettes has a magazine with three layer-accumulating sections having outlets at different levels and a set of pushers which expel layers of cigarettes from the sections during the intervals of dwell of an intermittently driven conveyor for a set of receptacles each of which accumulates an array by accepting one layer from each of the sections. The top and side walls of the receptacles have aligned slots for stationary and movable portions of retaining devices which prevent the cigarettes forming layers of incomplete arrays from moving relative to each other during abrupt acceleration and deceleration of the conveyor to move the receptacles from section to section. The undersides of movable portions of the retaining devices can be raised above or lowered into alignment with the undersides of the adjacent stationary portions through distances approximating the thickness of a layer. The movable portions are disposed in pairs at the second and third sections, and the stationary portions extend along the first section as well as between successive sections. The first movable portions of the two pairs are connected to each other for simultaneous up-and-down movement, the same as the second movable portions of the two pairs. All of the movable portions are lifted simultaneously when the conveyor comes to a halt, and the first portion of each pair is lowered ahead of the respective second portion while the conveyor is in motion.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
146 words
Apparatus for accumulating arrays of predetermined numbers of overlapping layers of parallel cigarettes or analogous rod-shaped articles, comprising a magazine arranged to store a supply of rod-shaped articles and including a series of equidistant layer-accumulating sections with outlet openings for layers disposed at different levels; conveyor means having equidistant receptacles each arranged to confine an array, said conveyor means being movable stepwise in a predetermined direction along a path extending past said sections so that successive receptacles register with successive sections during the intervals of dwell of the conveyor means; means for transferring layers from said sections into the registering receptacles during said intervals of dwell; and article retaining means adjacent to said path and including alternating stationary and movable portions, as considered in said direction, arranged to engage and hold the articles of the layers in receptacles containing fewer than said predetermined number of layers.
Claim 2
Dependent Claim
146 words

Claim 5
Dependent Claim
40 words
The apparatus of claim 1, wherein said sections include a foremost section for accumulation of the first layer of each array and a plurality of additional sections, said movable portions of said retaining means being adjacent to said additional sections.
Claim 6
Dependent Claim
46 words
The apparatus of claim 1, wherein said sections include a foremost section for accumulation of the first layer of each array and a plurality of additional sections, said stationary portions of said retaining means being disposed at said first section as well as between said sections.
Claim 7
Dependent Claim
15 words
The apparatus of claim 5, wherein said movable portions are adjacent to said additional sections.
Claim 8
Dependent Claim
21 words
The apparatus of claim 1, wherein said retaining means includes groups of movable portions adjacent to certain sections of said magazine.
Claim 9
Dependent Claim
21 words
The apparatus of claim 7, further comprising means for moving the portions of each of said groups relative to one another.
Claim 10
Dependent Claim
46 words
The apparatus of claim 8, wherein each of said groups comprises two movable portions and said moving means comprises means for moving the movable portions of each group substantially vertically and relative to one another during predetermined stages of each stepwise movement of said conveyor means.
Claim 11
Dependent Claim
42 words
The apparatus of claim 8, wherein each of said groups includes a first and a second movable portion, as considered in said direction, said moving means comprising means for simultaneously moving said first portions and means for simultaneously moving said second portions.
Claim 12
Dependent Claim
26 words
The apparatus of claim 8, wherein said moving means comprises driven cam means and follower means connected with said movable portions and tracking said cam means.
Claim 13
Dependent Claim
26 words
The apparatus of claim 11, wherein said cam means comprises a rotary cam having a plurality of endless tracks, one for each of said follower means.
Claim 14
Dependent Claim
22 words
