ALFRED GILMORE, of Keady, in the County of Armagh, Ireland, "AN IMPROVED
ATTACHMENT FOR SPINNING FRAMES"
This Invention relates to mechanism for automatically stopping the feeding of
the rove in spinning frames when the same becomes broken after passing through
the rollers which give motion to the same.
In carrying this Invention into practice, there is attached to the rove guide
which runs the entire length of the spinning frame, a bracket which forms at its
opposite end a guide or bearing for a vertical shaft which is free to rotate within
the same, Above the hereinbefore mentioned bracket and secured to the vertical
shaft, is an arm through which the rove runs to the feeding rollers.-At a
convenient distance below the feeding rollers there is secured another arm which.
at its outer end is bifurcated, and between whose bifurcations the rove passes.-This
second arm is provided with a horizontal quadrantal rack which is engaged with a
weighted rack or pinion pivoted upon any convenient part of the bracket before
mentioned. An eye is fixed to the lower edge of the beam of the frame or at any
other convenient part for affording a further guide or bearing for the vertical
shaft. To the lower end of the vertical shaft a third arm is secured. This arm is
pivoted upon a horizontal axis, and at its outer end (which rests when in operation
upon the thread plate of the spinning frame) is formed of wire its inner being so
weighted that if left free, the wire arm would be raised into a vertical position.
In the event of the rove or thread of yarn being broken, the mechanism herein-.
before described causes the same to be withdrawn sideways from the feeding
rollers, by the pivoted wire arm being released and thereby a part radial motion
given to the vertical shaft and with it the arms, guiding the rove, this motion being.
mparted by the weighted pinion or rack. The wire arm at the same time assumes
vertical or nearly vertical position being acted upon by the balance weight attached
thereto.

"
ALFRED GILMORE, of Keady, in the County of Armagh, Ireland, AN IMPROVED
ATTACHMENT FOR SPINNING FRAMES,"
My said Invention relates to mechanism for automatically stopping the feeding
of the rove in spinuing frames! when the same becomes broken after passing through
the rollers which give motion to the same.
J
In carrying this Invention into practice, there is attached to the rove guide
which runs the entire length of the spinning frame a bracket which forms at its
opposite end a guide or bearing for a vertical shaft which is free to rotate within
the same. Above the herein before mentioned bracket and secured to the vertical
shaft is an arm through, which the rove runs. to the feeding rollers. At a con-
venient distance below the feeding rollers there is secured another arm which at
its outer end is preferably bifurcated and between whose bifurcations the rove
passes. This second arm, according to one modification in the carrying out of my
said Invention is provided with a horizontal quadrantal rack which is engaged
with a weighted rack or pinion pivoted upon any convenient part of the bracket
before mentioned. An eye is fixed to the lower edge of the beam of the frame or
at any other convenient part for affording a further guide or bearing for the vertical
shaft. To the lower end of the vertical shaft a third arm is secured.-This arm is
pivoted upon a horizontal, axis and at its outer end (which rests when in operation
upon the thread plate of the spinning frame) consists of a wire rod; its inner end
being so weighted that the wire if left free, in a certain position would be raised
towards a vertical position.
In the event of the rove or thread of yarn being broken, the pivoted wire arm,
which is under the influence of the balanced weight, is released and thereby a
part rádial motion given to the vertical shaft, and with it the arins, guiding the
rove, and the rove or thread being thus withdrawn from the feeding rollers its feed
is stopped until the thread is pieced up.
And in order that my said Invention may be properly understood I now proceed
more particularly to set forth the system, mode or manner in or under which the
same is or may be used or practically carried into effect, reference being had to the
accompanying Drawings and to the Letters and Figures marked thereon, that is
to say :-
Figure 1, of the accompanying Drawings represents partly in elevation. and
partly in section a, spinuing frame with the attachments for carrying out my
Invention, applied thereto.
To the rove guide a, which runs the entire length of the spinning frame, is
attached or is suspended by the pin b, the bracket B, which, forms a guide or
bearing for the vertical shaft of spindle, which
which is free to rotate within the
saine. Above the said bracket and secured to the vertical shaft is the arm-D,
through which the rove x, runs to the feeding rollers E.-The said arm as shewn
also in plan, Figure 1, is keyed to the shaft C, by the pinching screw d, and the
outer end of the arm is formed with an eye d¹, for, the rove to run through.
Below the feeding rollers E, as shewn, in Figure 1, is the ar
arm. F, which is, also
1890
keyed upon the shaft C, by the pinching screw f, the outer end of the said arm
being preferably bifurcated as shewn in plan, Figure 1, the rove passing between
the bifurcations. The said arm F, is formed with a quadrantal rack f¹-Into the
said rack, the pinion G, gears, the said pinion (Figure 1,) being mounted or

page_text: pivoted at o upon the portion B, of the bracket B, in which the shaft C, swings
round, as shewn more particularly in Figure 1°, which is an elevation of the rack
and pinion gear as detached from the frame.-The said pinion G, is formed with a
continuation or upper portion g, which forms a weight balanced upon the pin b¹.
The spindle C, below the guide or bearing h, which is attached to the beam H, of
the frame, has secured to the extremity thereof the arm -The said arm is
pivoted at ¹, upon a horizontal axis, the outer end of the said arm being formed as
a wire or rod of brass or other suitable material which rests upon the hinged
thread plate J, of the spinning frame.-The inner end of the said arm or the part
in proximity to the shaft C, is formed as a weight 2, the said weight being so
constructed and arranged with regard to the remainder of the arm, that when left
free in a certain position the wire or rod portion of the arm would be overbalanced
and thus raised up towards a vertical position, as hereinafter explained.-The
attachments of the spinning frame being thus constructed and arranged I will
proceed to describe the action of the same when brought into operation to stop
automatically the running out of the rove when the thread has broken.-In
Figure 1, the rove is marked x, and is shewn running out from the part X, through
the two pairs of feeding rollers E, and E', to the flyer Y.-In the event of the
thread breaking say at a point between the rollers E¹, and the plate J, the wire
rod i, immediately flies round sideways from the thread under the influence of the
weight g, of the pinion G, in the following manner. The wire i, in its normal
position and as shewn in the drawing is only prevented from flying round by the
said wire resting against the one side of the thread, when therefore this support of
thread is taken away by reason of the breaking of the thread, the weight g, of the
-pinion C, which when in its normal position leans slightly forward as shewn, falls
forward into the position indicated by the dot and pick lines, Figure 1, carrying
the shaft C, round with it and in so doing brings the arm F, round in a horizontal
direction and simultaneously the upper arm D, the rove therefore is caused to
follow the movement of the arms and is thereby thrown out of the catch of the
two pairs of feeding rollers and thus the run of the rove is stopped until the
spinner comes forward to piece up the end.-The wire i, is overbalanced by the
weight, when thrown up by the hand before doffing the full bobbins when
the thread plate is thrown up also upon its hinge, and the flyers and bobbins are
taken off. When the wire i, is thrown up by the hand it lies at the left-hand side
of the pressing roller E¹, thus keeping the rove in its place during the doffing and
allowing the loose ends or thread to be replaced round the empty bobbin after
which the wire i, is pulled down again and laid against the thread before the frame.
is started again after doffing.
-
In piecing up the broken ends of the thread the spinner first stops the flyer as
usual with his or her left hand and pulls the end up off the bobbin with her right
hand at the same time while her left hand is on the flyer Y, pulls forward from
right to left, the wire i, while placing the thread or end in the eye j, of the
plate J, then changing the thread into her left hand pieces up as usual the end
which is now through the pairs of rollers E, and E', as immediately on pulling
forward the wire i, from right to left the top arm D, and the bifurcated arm F,
return to their former position and feed the rove x, into the rollers again.
When the spinner requires to "lay" the end on the bobbin she pulls back the
wire i, further than at other times making the weight g, of the pinion G, incline
back over the centre in the opposite direction thus keeping the wire i, away from
the thread until the end is pieced up then she replaces the said wire against the
thread as usual.
In lieu of employing a separate weight.g, for actuating the wire i, I may
modify the arrangement by so constructing the spindle and attachment as to cause
the weight of the spindle itself with its attachment to effect the same object.
The modification consists as follows:-reference being had to Figure 2, of the
second Sheet of Drawings (the same letters of reference in this Sheet of Drawings
as in Sheet 1, indicating corresponding parts.)-The bracket B', corresponding to

page_text: the bracket B, of Figure 1, has formed upon its top or that part which is in
proximity to the top of the spindle C, an inclined portion b', and the underside of
the rove guiding arm D¹, corresponding to the arm D, Figure 1, is formed with
an inclined portion d', coinciding with the inclined portion b¹, of the bracket B-
The whole weight of the spindle and, its attachments is caused to rest upon the
incline b¹, of the bracket B', and while the rove or thread is running the upper
incline d², will rest upon. the lower or corresponding incline b¹, at its upper part
thereof as shewn at Figure 2, when however the thread breaks and the wire rod i,'
(which is constructed and operates essentially as described with reference to
Figure 1) is caused to swing round away from the thread the weight of the
spindle and its attachments is thus allowed to fall, that is to say the inclined
portion d, of the arm D¹, is caused to fall down the incline b', and thus assume
the position shewn at Figure 2b, and in so doing the spindle has imparted to it a
motion of partial rotation, and with it the two guiding arms D¹, and F¹, which
conduct, by their side movement, the rove out of the feeding rollers E; and E¹, and
the run of the rove is thus stopped.-It is obvious that in this modification the
lower extremity of the spindle is free to move in the guiding collar h, which is
attached to the beam H, of the frame..
In Figure 2, I have shewn a modification in the construction of the inclines in
which the inclined portion d*, of the arm D¹, rests upon a roller 62; mounted upon
the bracket B¹, it is obvious however that the particular construction of the parts
to give a vertical motion and at the same time à motion of partial rotation to the
shaft to impart the necessary side movement to the arms guiding the thread, may
be varied in many ways.
Having now described and particularly ascertained the nature of my said
Invention and the system, mode or manner in or under which the same is or may
be used or practically carried into effect, I would.observe in, conclusion that what I
consider to be novel and original and therefore claim as the Invention secured to
me by the hereinbefore in part recited Letters Patent is :-
1. In spinning frames the attachment for stopping automatically the feeding of the
rove when the same becomes broken, consisting, essentially of the shaft C, wire i,
weight g, and guiding arms D, and F, all operating in combination and with their
attachments in the manner described with reference to Sheet 1, of the accompanying
Drawings or the mechanical equivalents such for example as that hereinbefore
described with reference to sheet 2, of the accompanying Drawings.
In witness whereof I the said Alfred Gilmore have hereunto set my hand
and seal this Twenty-second day of August in the year of Our Lord one thousand
eight hundred and Eighty-three.
