This invention relates to can doiîers and particularly
to can doiîers which operate automatically to move a
can from beneath a coiler head of a coiler mechanism
when a predetermined amount of sliver has been de
livered to the can from the coiler head.
ln the present invention a can doll'er of novel and
and means for automatically indexing the support when
a predetermined length of sliver has been coiled into a
can so that a ñlled can is displaced from beneath the
coiler head and an empty can is positioned beneath the
coiler head.
It is another object of the invention to provide a can

The drive means for rotating the turntables is prefer
ably a reversible drive so that the direction of rotation
of a can being ñlled is automatically periodically re

includes a driving gear which cooperates with gear teeth
formed on the peripheries of the turntables to effect
rotation of the turntable supporting the can being filled. ‘
The arrangement is such that when the drive for the
support is operatively connected to the support, the turn
table drive is connected So that the teeth yon the driving
gear are moving in generally the same direction as the
teeth on the turntable during rotation of the support.
The invention also provides that the driving gear is re
siliently biased toward the teeth on the turntable so
that the driving gear may be moved away from the
teeth when initially contacted thereby. This arrange
ment minimizes the possibility that the driving gear and
the teeth on the turntable which is moving into posi

bore 77. The spring 76 engages at its other end a screw
cam followers in the form of rollers 118 and 119 which
are rotatably mounted o-n opposing sides of the plate 120
and which are spaced arcuately on the plate 120. The
plate 128 is secured to a sleeve 121 which is mounted by
bearings 122 for rotation about a stationary post 123
7S closing the bore 77 and biases the plunger 72, the
bracket 69 and the gear 66 about the axis of the stud 79
to their illustrated positions. With the described arrange
ment the gear 66 may be pivoted about the stud 70 against
the action of the spring 76 when the gear 66 is engaged
by the teeth 71 of the approaching turntable so that
proper meshing of the teeth 71 with the gear 66 may be
obtained. As will presently appear, the gear 66 is rotated
about the axis of shaft 67 in a clockwise direction as
viewed in FIG. 4 during movement of a turntable toward
the gear 66 so that the teeth 71 of this turntable and
the gear 66 are moving in generally the saine >direction
when initially engaged.
The switch Si) is of a conventional type which is op
erated by rotation of a shaft 88 keyed to a sleeve 81 fixed
to the lower end of the shaft 26 as viewed in FIG. 3.
The switch 50 controls the opening and closing of con
tacts S11-«1 and Sti-2 (FIG. l2) connected in parallel
relation between power conductors L1 and L2 in a cir
cuit including a coil S41 of a can reverse relay.
rfinis
relay includes normally open contacts 841-1 and .8d-2
and normally closed contacts 84-3. As will presently ap«
pear, the switch 50 controls energization of the solenoids
23 and 59 so that the conditions of energization of the
solenoids 23 and 39 are periodically reversed in response
to rotation of the shaft Sii. A switch suitable for this
purpose may be obtained from the Gernco Electric Corn~
pany of Detroit, Michigan, and is designated as a Gemco
attached to the base 115. A gear 124 is formed on the
sleeve 121 and meshes with a gear 125' operatively as
30 sociated with the support 6.
The contigurations of the cams 116 and 1‘17 are best
shown in FIG. 8. As there shown the cams are each of
generally heart~shaped configuration and are secured to
the sleeve 112 so `as to be spaced 'angularly relative to each
other about the axis of the post 114. The cams 116 and
117 include respectively shoulders 126 `and 127 adapted
to engage the rollers 118 and 119 on the plate 128. These
rollers are yarranged so that the rollers 118 are mounted
on the upper surface of the plate 128 and the rollers 119
40 are mounted on the lower surface of the plate.
T-he
roiiers are in alternating relation Ias viewed in FIG. 8
such that a roller 118 on the upper surface of the plate
is spaced angularly about the axis of the plate from the
adjacent roller 119 on the lower surface of the plate.
With the described arrangement, when the cams 116
and 117 are rotated, for example, in a counterclockwise
direction as viewed in FIG. 8 from the positions shown,
the shoulder 127 of the cam 117 engages a roller 119 to
effect rotation of the plate 1.20 in a clockwise direction.
When the earns have been rotated through an angle of
approximately forty-tive degrees from the positions shown
the cain 117 will become disengaged from the previously
engaged roller 119 and the shoulder 126 of the cam 116
will engage the Vadjacent roller 118 which has now moved

side of the plate 120 or about seventy-two degrees.
Details of the support 6 may now be described. The
gear 125 is formed on a sleeve 130 supported for rotation
by a bearing 131 secured to the base 115. A center post

normally closed contacts 145-3 open to deenergize the
solenoid 109’ of the brake 1&9. As a result, the drive

the plate 135 as it rotates about its axis. Rods 137’ are
attached to the post 132 spaced about the axis of the
post to prevent the cans from falling from the support 6
during rotation thereof.
The turntables 7 are of identical construction and are
mounted on the support 6 in an identical manner. In
FIG. 9 only one of the turntables is shown in detail and
comprises a plate 138 having an annular shoulder 139 at
its circumference and on which is positioned an annular

driving gear 66 is rotated in a clockwise direction as
viewed in FIG. 4 »as the support is indexed in a counter~
clockwise direction. As a result, the teeth of gear 66
and the teeth 71 of the turntable supporting the empty
can are moving in generally the same direction.
When the support 6 has indexed to a position wherein
the empty can is positioned beneath the coiler head an
arm 149 of an index stop switch `150 shown in FIG. 8
is actuated by an actuator 151 on the support. When
this occurs the normally closed contacts 150-1 of the
switch 150 are opened to interrupt the sealing circuit for
