"Improvements in Coilers, suitable for Use in connection with
Textile Machinery.
I, JOHN TEMPEST MEATS, residing at 6 Clinton Street, in the City of
Taunton, County of Bristol, State of Massachusetts, United States of America,
Superintendent, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This invention has for its object to improve and simplify the construction of
coilers used to coil textile material in cans.
The primary feature of my invention is embodied in a divided cover for the
casing, said parts to open and close after the manner of jaws, preferably to swing
in a longitudinal plane from over the operating parts. In this way the casing can
be opened and ready access be had to the coiling mechanism within, either for
inspection, or oiling, and without the necessity of breaking the sliver. My
improvements are further embodied in the feed rollers and in the peculiar manner
of mounting the same, whereby they are permitted to have ample lateral movement
to prevent breakage in case the material which ought to pass between the rolls
becomes wound thereon; an accident which not infrequently occurs. Thus the
roller, which yields to the accumulation of material on it, is so supported that when
it once yields to increase of pressure and the separation of the rolls takes place,
said pressure is maintained substantially uniform irrespective of the distance the
rolls are apart, or in other words the movement of one roll from the other.
Particular features of my invention will be hereinafter more fully described,
and pointed out in the claims at the end of this specification.
Figure 1 shows in top or plan view a sufficient portion of a coiler to enable my
invention to be understood;
Fig. 2, a view showing the cover and casing and some other usual parts in
section;
Fig. 3, a plan view with the cover separated to expose the rolls, the latter being
separated and the trumpet omitted.
Fig. 4 is a cross-section of the boxes in which the roller-shafts rotate, the boxes
being in their closed positions ;
Fig. 5, a like view with the boxes separated as they will be when a roll has
accumulated sliver upon it;
Fig. 6 is a section in the line xx, Fig. 1 ; and Fig. 7 is an end elevation of the
coiler in direction of arrow 1, in Fig. 2.
The pillar or column A (partially shown in Fig. 2) has a suitable foot to
rest on the floor, and at its upper end it supports the bed-plate A', cut away
centrally to receive the large coiler-gear A³, having an inclined passage A' to
receive the sliver and deliver it into the usual cans, (not shown,) which stand
directly under the said gear. The pillar has a shaft B, driven by power in
usual manner, the said shaft having near its upper end a gear B', which engages
and rotates the coiling-gear A³, and immediately above the gear B₁ the said shaft
carries a bevel-gear B, which engages a bevel-gear B³, fast on and rotating the
shaft B of the main cylinder-roll B, said shaft also carrying a pinion B, which
engages the pinion C, fast on the shaft C³, carrying the cylinder-roll C².

page_text: The main shaft B has its bearing in a box D, held in place by a suitable
screw D'; but the shaft C' has its bearing in a box D2, connected to or forming a
part of an arm or radius-bar D³, pivoted at D', so that said bearing can swing
laterally when the material passing between the rolls becomes caught and coiled
about one or both rolls, the bearing then sliding on the cross-pieces or track E³,
attached to the casing E¹, adapted to turn about a horizontal pivot E³, held in the
bed-plate. By thus removing the pivot D a considerable distance from the rolls
any unusual lateral movement of the roll C will throw it out of gear with the
roll B, as shown in Fig. 3, thereby instantly stopping further coiling or winding
movement of the roll C². The bearing-box D2 may, however, have this provision
of bodily lateral movement by any suitable means other than the long radius-
bar D³.
The casing has a projection E, which may be engaged by hand when it is desired
to turn the casing up and uncover the gearing inside of it.
The movable bearing is acted upon by a friction device (shown as a spring a)
held in place by a screw a', so shaped as to overlap the bearing D² to hold the
rolls B and C together, to enable the said rolls to properly act on the sliver and
feed the same into the guide A³.
In case the sliver becomes wound about one of the rolls it will continue to
accumulate and the rolls must separate or the mechanism will break. The
bearing D may yield under these circumstances, and as it moves (see Fig. 5) the
friction device a continues by its end a² to act on the bearing and insures that
the friction or resistance which the bearing has to overcome in order to move is
uniform. If a spiral compression-spring should be used, the pressure to overcome
would be gradually increased.
By enabling the roller C³ to yield laterally in a horizontal plane its range of
motion is greatly increased and there is no danger of its striking any other part,
which would stop it or result in breakage.
Instead of the particular friction device shown I may use any other equivalent
friction device acting on the bearing D² or its carrying-arm.
The cover plate is composed of two swinging parts d d', mounted upon a pivot d²,
fixed by a screw in a lug attached to the interior of the casing E. The part d
is preferably slightly concaved and rounded at d, while the pivot dis extended
above the surface of the part d', (see Fig. 7) to serve as a guide for the sliver.
In lieu of this construction a sliver-guide proper may be affixed to the outer
surface to perform a similar duty; that is to properly direct the sliver on its way
to the trumpet e. The trumpet e is carried by an arm el, pivoted at e on an ear e³,
herein shown (see Fig. 3) as erected on the bearing D. By mounting the trumpet
independently of the cover and dividing the cover the rolls C² and B' and their
driving-gear may be readily made accessible by only separating the cover, one
part of the cover having a suitable catch, as f, shown as a spring adapted to engage
a lug on the other part, the spring having an attached button, which may be
depressed to disengage the spring from the lug.
In my invention by making the cover in two parts and mounting the same on a
vertical pivot the cover may be readily swung apart horizontally and fully uncover
the rolls and their driving mechanism, the sliver remaining in the guide and
trumpet, and by tipping the casing up about the pivot E2 the coiler-gear may be
reached and removed, if desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is:
1. In a coiler, the two-part centrally-divided cover suitably mounted, and
adapted to swing from over the coiler mechanism, and permit access thereto
without breaking the sliver, substantially as set forth.
2. In a coiler, the combination with a main roll B, its shaft, a bearing for the
shaft, and means to rotate the shaft, of a second shaft having a roll C³, pinions on

page_text: said shaft to cause the said main shaft to revolve the said second shaft, a bearing
for the said second shaft and a radius-bar carrying the said bearing, said radius-
bar being mounted on a vertical pivot located substantially as described, whereby
the separation of the said rolls by the accumulation of fibre disengages the said
pinions, said radius-bar moving freely in the arc of a horizontal circle, substantially
as described.
3. In a coiler, a trumpet, a coiler-gear, and a pair of rolls mounted side by side
to feed the sliver into said coiler-gear, a horizontally-movable bearing for one of
said rolls, said bearing having a flattened side, combined with a friction device
adapted to ride on the flattened side of the bearing to thus insure uniformity of
pressure on the material wound on the roll, substantially as described.
4. In a coiler, the coiling-gear, feed-rolls located above it and relatively movable
horizontally, and a spring co-operating with the shaft carrying one of said rolls to
retain the rolls in yielding relation, combined with a two-part cover mounted on a
vertical pivot and movable in a horizontal plane from over and to fully expose
the said rolls and their actuating-gear, each part of the cover being movable
independently of the other, substantially as described.
5. In a coiler, the two-part centrally-divided cover mounted on a vertical pivot,
one of said parts being provided with a sliver-guide, combined with a trumpet
sustained independently of said cover and with the pair of rolls B, C, one of the
shafts of said rolls being movable in a horizontal plane away from the other of said
shafts, substantially as described.
6. In a coiler, the two-part centrally-divided cover mounted on a vertical pivot,
and a sliver-guide attached to one of said parts and comprising the extended
portion of the pivot, and a curved recess in the cover, combined with a trumpet
independently of the cover, and a pair of rolls to co-operate with the trumpet in
advancing the sliver, one of the said rolls being movable in a horizontal plane
to and fro with respect to the other of said shafts, substantially as specified.
7. The shaft B, its stationary bearing, and the shaft and its movable bearing,
said two shafts being provided with rolls, combined with a spring suitably secured
to the machine, said spring shaped to yieldingly embrace said movable bearing, the
said spring exerting uniform pressure on the top of the said bearing when the rolls
are unduly separated, substantially as described.
8. In a coiler, a casing mounted on a horizontal pivot, a trumpet carried by said
casing, combined with a cover mounted on a vertical pivot carried by said casing,
and centrally apertured to fit snugly around said trumpet, substantially as
described.
9. In a coiler the two-part centrally-divided cover, a vertical pivot on which
the parts swing independently, said parts to move in a horizontal plane from over
and to fully expose the rolls and actuating gear of the coiler, without interrupting
the sliver, substantially as stated.
