JAMES MACKIE, Machine Maker, Springfield Road, Belfast, and CHARLES
DRENNAN, Foreman Fitter in Machine Works, Battenberg Street, Belfast in the
County of Antrim do hereby declare the nature of this invention to be as
follows:-
This invention relates chiefly to the substitution of dead or fixed rods or plates,
in place of the usual revolving rollers employed in retaining and feeding slivers
into the gills of preparing and gill spinning machinery.
In the simplest form these consist of two or more bars, so disposed that the
slivers must pass under and over between them in series. The distance of the
bars apart, as well as their relative positions being adjustable to give more or less
friction to the sliver in passing through as desired. The last bar in all cases, that,
is to say, the one nearest the gills is preferably placed so as to have its under side
about level with the bottom of the gills. Where two bars only are employed, the
first bar may be carried in brackets in such a position as to lie upon or against
the second bar, and by its weight retain the slivers passing between the two bars.
The upper bar may be of any length to retain one or more slivers, whilst the lower
bar is continuous. For guiding the slivers, fixed or adjustable pieces may be
attached to the bars, both where the slivers enters and, where they are delivered
upon the gills. Or conductors may be set upon separate bars independent of the
retaining bars. The retaining bars may be of any convenient section either solid,
hollow, rolled or folded and of any suitable material. For facility in introducing
the slivers, some one or any of the bars may be made movable in any convenient
direction & capable of being readily set & fixed in position.
The bars may be also so arranged as to act as detectors in case of a dropped
sliver, in which case one of the bars may be substituted by a lever or other suitable
contrivance which changes position when a sliver breakes & thus makes an
electric or mechanical contact capable of giving alarm or stopping the machine.
Where Rollers are used in the ordinary way a conductor bar having fixed or
adjustable conductors may be introduced between the last roller & the gills.

page_text: County of Antrim, 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 relates chiefly to the substitution of dead or fixed rods or plates,
in place of the usual revolving rollers employed in retaining and feeding slivers
into the gills of preparing and gill spinning machinery.
In the simplest form these consist of two or more bars, so
disposed that the
slivers must pass under and over between them in series. The distance of the
bars apart, as well as their relative positions being adjustable to give more or less
friction to the sliver in passing through as desired. The last bar in all cases, that
is to say, the one nearest the gills is preferably placed so as to have its under side
about level with the bottom of the gills. Where two bars only are employed, the
first bar may be carried in brackets in such a position as to be upon or against the
second bar, and by its weight retain the slivers passing between the two bars.
The upper bar may be of any length to retain one or more slivers, whilst the lower
bar is continuous. For guiding the slivers fixed or adjustable pieces may be
attached to the bars, both where the slivers enter and where they are delivered
upon the gills, or conductors may be set upon separate bars independent of the
retaining bars. The retaining bars may be of any convenient section either solid,
hollow, rolled, or folded, or of any suitable material. For facility in introducing
the slivers, some one, or any of the bars may be made movable in any convenient
direction, and capable of being readily set and fixed in position.
The bars may be also so arranged as to act as detectors in case of a dropped
sliver, in which case one of the bars may be substituted by a lever or other suitable
contrivance which changes position when a sliver breaks and thus makes an
electric or mechanical contact capable of giving alarm or stopping the machine.
Where rollers are used in the ordinary way a conductor bar having fixed or
adjustable conductors may be introduced between the last roller and the gills.
This invention may be carried out in several ways as will be fully shown by the
following description and accompanying drawings. The figures on Sheet 2 being
views in plan of the corresponding figures in Sheet 1.
Fig. 1, represents a sectional elevation of the back of a gill box showing the sliver
as a dotted line a passing under and over the bars d³, da, d, into the fallers c of
which only the first one is shown. Upon the bars d' and conductors to confine
the sides of the slivers may be attached.
The distance apart of the bars may be regulated but the bar nearest the
fallers would remain in a constant position.
Fig. 2, shows the sliver passing over a bar around it and between the two
bars d' and d, the upper bar resting by its own weight upon the sliver, a con-
ductor e is shown attached to the lower bar d¹.
Fig. 3, shows the sliver passing in a direct line between an upper and lower
bar and d, the upper bar being made in the form of a shell for lightness.
Different forms of conductors e¹ and e² are shown, the latter e² being applicable
where revolving rollers are employed instead of dead bars. It is held upon a
barf beneath and behind the gills c and between them and the rollers or bars d.
Fig. 5, shows an arrangement similar to Fig. 2, but the bars are held apart
instead of lying one upon the other.
с
Fig. 6, illustrates another shape of bars d, the upper one resting upon the
lower one with pins passing up through it to hold it in position.
The upper bars in Figs. 2, 3, 5, and 6, may be continuous for a number of slivers
or may be sectional for one or more slivers each.
Fig. 4, represents the employment of a dead bar in connection with a stop
motion in case of a sliver a either breaking or being too thick. A lever g resting
on a fulcrum h has one end made to lie up against the bar d and put a slight
pressure upon the sliver a, lugs e on each side of the lever act as conductors to
confine the sliver sideways. At the other end a jaw J is formed which is wide

page_text: enough to admit of the bar i mounted upon the lever K to oscillate in and out of
it when the sliver is of correct thickness and maintains the lever g in a normal
position. When the sliver is too thick or broken off the lever rises or falls causing
one of the lugs above or below the jaw J to come in contact with and check the
oscillation of the bar and lever K.
The motion given to the levers K and bar i is through the shaft and lever / from
the eccentric rod m through the link n. At the lower end of link n is a latch O
drawn by a spring into a notch upon the belt rod 1'. So long as the levers g and
jaws J are all in correct position the bar i and levers K and 7 are free to oscillate
but immediately the motion of the bar i is arrested by coming in contact with one
of the lugs of the jaw J, the upper end of link n remains stationary and the lower
end with latch O is pushed forward against the pressure of the spring thus releasing
the belt rod P which is made to push the belt into the loose pulley by means of a
weight or spring.
Fig. 7, shows a similar arrangement to Fig. 4, but having instead of the
mechanical stop motion an electrical contact for giving alarm when a sliver is too
thick or broken away. As in Fig. 4, the levers K and bar i are made to oscillate
with a positive motion. Upon the bar i which is electrically insulated from the
rest of the frame and connected with an electrical circuit ay are mounted tongues
which mass freely between the jaws J. But when the lever g dips in either direc-
tion the tongue rubs on one side of the jaws and completes an electrical circuit,
in which a bell may be placed for giving alarm, or an electromagnet may be set
in action to draw a latch out of the belt rod which is operated by a spring or
weight.
The lever y and connections for stop motion or alarm may also be applied to the
bar in Fig. 1.
Having now particularly described and ascertained the nature of our said In-
vention and in what manner the same is to be performed we declare that what
we claim is:-
1. The employment of stationary rods over, or around or between which the
slivers are made to pass in order to cause them to enter the fallers with a suitable
tension, substantially as described and shown in Figs. 1, 2, 3, 5, and 6.
2. The employment of conductors attached to the said rods substantially as
shown in Figs. 1, 2, 3, 5, and 6.
3. The application of conductors to a separate rod and guiding the sliver
immediately before entering the fallers, and between them and the said rods
substantially as shown in Fig. 3.
4. The employment of a lever to press the sliver against one of the said rods so
that in case the sliver is broken or becomes too thick the lever actuates a motion
to stop the machine substantially as described and shown in Fig. 4.
5. The employment of a lever to press the sliver against one of the said rods so
that in case the sliver is broken or becomes too thick the lever comes in contact
with a moving tongue making an electrical contact to give alarm or stop the
machine substantially as described and shown in Fig. 7.
