13 Claims.
(01. 242-78)
This invention relates to a machine for coiling
sheet material, more particularly it relates to an
improved coiling drum having relatively movable sections, whereby it may be readily collapsed
5 and expanded to facilitate attachment of the material for winding and removal of the coiled material.
»
consisting of a plurality of longitudinally extend
ing sections, which are arc-shaped in cross sec
tion, namely, a stationary section 411, and mova
ble sections lb, 4b‘, 4c, the latter sections when ex
panded co-operating with each other and the 5
section la to form a substantially continuous cy
lindrical surface on which the material A is coiled
" The machine herein shown for illustrative purposes is adapted for coiling sheet metal of any
10 width within the length of the drum, but, the in-
sleeve member 3b, preferably secured together by 10
ventlon is not to be limited to this particular application as other materials may be coiled on the
drum. '

One object of the invention is to provide an im-
15 proved drum of this type that is readily controlled and actuated whereby the operations of

shaft 3 consists of an inner member 3a and a

sunk bolts 8., The head 8 has a diameter sub- ‘
stantially equal to that-of the drum 4 to close the 15
outer end thereof. The sleeve member 3b is pro
attaching the sheet materiahcoiling it and re-

driving mechanism having a suitable‘ gear reduction and reversing means for driving a'shaft
3, as hereinafter set forth, said mechanism being
50 driven by a motor 4’. The shaft 3 is mounted
in suitable hearings in the housing 2 and extends
rearwardly beyond the housing to provide for a
. brake wheel 5, which is controlled by a suitable
brake mechanism 6. The shaft 3 extends beyond
55 the front of the housing 2 to support a drum 4,
shown in Fig- 3, I provide a plurality of interme-‘
diate lugs 10-’ having, by preference, bearings for
the Shafts -.| l and rods l5 and Preferably seats to
which the stationary drum section may be se
cured. Furthermore and by preference, these 50
intermediate 1118s (01' Certain thereof) are Shaped
at diametrical opposite sides to form guide ways
ll, which extend in parallel relation to each
other and transversely to the axis of the drum,
and receive and support a pair or pairs of thrust 55

devices it. The thrust devices it; are connected
at corresponding ends (preferably integrally)
to a pair of arms 59 integral with and extending
inwardly from the movable-drum section to and
accordingly slidably support the latter on the
shaft for movement radially thereof; but as the
lugs |0',-in which the thrust members it are
mounted, are connected to and rotate with the
shaft member 312-, it will be seen that the movable
10 drum section 40 rotates therewith at all times
and that no relative rotative movement between
them is effected when the section is moved out
wardly or inwardly or otherwise- The movable
section 40 is connected to the sections 4b, 46, by
pairs of links 20, each pivoted at its opposite ends
to the adjacent sections, and so arranged that
radial movement of the section 40 inwardly will
effect an inward swinging movement of the sec
tions 41), 4b, simultaneously about the rods l5
20 and outward radial‘ movement of the section 40
will swing the sections 4b, 4b, simultaneously
outwardly; the parts being correlated so that
when the sections 4b‘, 4b, 4c, are moved outward_
ly or expanded, they co-operate with each other
with the‘ racks 2t and ?xed to the shafts ||. At
their inner ends the shafts ii are provided with
the gears M, Ma, already referred to. The gear
it meshes with the gear teeth 26 provided on the
collar 2|, whereas the gear Ha meshes with an
idler 27 which in turn meshes with the teeth 26,
whereby are secured proper directional move
ments of the shafts Ii.
The idler 21 is rotatably supported on a shaft
carried by thefree end of a bracket 21' bolted to 10
the innermost lug I0 on the shaft member 3b and
drum section la (see Figs. 6 and 7).
The collar 2| is mounted in bearings 2 la in the
front wall 2a of the housing 2 and is preferably
formed integral“ with a gear 2|’ which is con 15
nected to and driven by the driving mechanism
(not shown) within the housing 2. The gear 2|’
is arranged between the housing wall 2a and a
shoulder 31: on the shaft 3 to prevent endwise
20
movement of the collar.
From the foregoing description it will be under
stood that when the driving mechanism is
started, the collar ‘2| will first or initially rotate
relative to the shaft 3 an angular distance de
termined by the width of the key-ways 23 and 25
and the stationary section 4a. to form a continu
ous winding surface for the material A, as shown ‘ thereafter through the keys 22, it will become
in Fig. 4. In this latter position of the drum drivingly connected to the shaft 3 to rotate the
drum and effect coiling of the material thereon.
sections 4b, 4b, 40, the links 20 by preference ex
tend at substantially right angles to the direction
30 of movement of the thrust devices l8, sothat (a)
in the movement of these devices inwardly (to
ward the left in Fig. 4) to the position shown in
Fig. 5, the section 40 is moved inwardly radially
and the sections lb, 411, are swung inwardly,
35 whereby the drum is contracted or collapsed, and
(b) in the movement of these devices in the op
posite direction, the sections 4b, 4b, 4c, are ex
panded to the position shown in Fig. 4. Accord
ingly in my construction, I operate one drum
40 section inwardly and outwardly and through it
' I operate the other movable sections.
During this initial movement of the collar, it
will cause a rotation of the shafts | |, and through 30
the gears 25 thereon and racks 24 on the thrust
devices, the drum sections will be expanded. At
the end of the coiling operation, the rotation of
the collar is stopped, permitting the momentum
of the shaft 3 and drum to rotate relative to the 35
collar 2|, whereby the moving means for the‘
thrust devices'will effect a collapsing of the mov
able drum sections. However, if these sections do
not become collapsed, the collar 2| may be ro
tated in the opposite direction far enough to 40
move the movable drum sections to their col_
The links 2|) are pivoted to the sections 4b, 4b, lapsed position.
The stationary drum section 4a is cut away
40, by means of rods 20' which extend longitudi
nally of the drum through openings formed in ' along one longitudinal edge to provide a recess 28
in which is removably fixed a clamping member
