In the complete speci?cation and drawings of copend

suitable shapes to enable them to clear any obstructions

The said movable parts may be pivoted on their re

may have pivoted ?aps at its extreme ends, which flaps
are spring-urged upwardly towards positions at which
they extend obliquely from the support to the con?ning

swing back, riding over the rollers as the pusher moves

be seen that the roller 74} permits a corner portion 65 to
swing about its pivot with little friction or wear on the
front face of the portion 65.
When the pusher returns, the corner portion 65 swings
back to its normal position as it moves past the roller

It will be understood that the mechanism illustrated

lowering of the platform 15 then proceeds for the sec
ond time. So far, the flaps 34, FIGURES 4 and 5, have
remained ?ush with the remainder of the con?ning walls
140 and in line with the upper walls or strippers 4, thus
allowing cigarettes to be fed down freely and to form a
stack extending from one end wall 14% to the other. As
the container 11, carried by the chains 83, approaches its
lowest position, however, the face 51 of the member 50
connected to the chains 83 engages the roller 55, thus
swinging the lever 47 so that the pin 48 pushes the link
43 to the right, FIGURE 4, and thereby brings the pin
44 into the range of action of the end of the arm 60.
Accordingly as the platform 15 reaches its lowermost
position, and member 62 depresses the arm 60, the latter
engages the pin 44 and pulls the link 43 downwardly.
As a result, the bell-crank 38, 39, is rocked and the roller
42 presses the ?ap 34 inwardly to the position shown
in dot-and-dash line in FIGURE 4 and in full line in
FIGURE 5.
The above description refers only to the mechanism
at one end of the apparatus, but it will be understood that
the identical mechanism provided at the opposite end
operates in the same way.
What we claim as our invention and desire to secure
by Letters Patent is:
l. Cigarette-collecting apparatus comprising a support,
means to feed cigarettes downwardly on to the support
on which they form a stack, means to move the support
downwardly to lower the stack during its formation, up
right con?ning walls between which the support is moved
down, the said support and the said con?ning walls con
stituting con?ning members which con?ne the stack dur
ing its formation, a pusher to push a stack across the
support, means to support a container in a position to
receive said stack from the support, means to raise the
support, means operative, after a stack of the required
size has been formed on the support, to prevent further
cigarettes from moving down until the stack has been
pushed across the support into an adjacent container and
the support has been raised to receive further cigarettes,
wherein at least one of the said con?ning members com
prises movable parts located where those edges of a com
pleted stack which are in contact with the said con?ning
walls will be located, and means to cause each such mov
able part to assume a position in the same plane as the
member of which it forms part, for facilitating the forma
