Improvements in Means for the Prevention of
Snarls" and Lashed
Ends" in Ring Spinning and Doubling Frames.
I SAMUEL DRONSFIELD of the Windsor Mills, Lissadel Street, Pendleton, in the
County of Lancaster, Manager, do hereby declare the nature of this Invention to be
as follows:-

My Invention relates to ring spinning and doubling machinery and has for its
object to prevent or lessen the formation of "snarls" and "lashed ends." When
an end of yarn breaks it tends to fly outward and to come into contact or become
entangled with adjacent ends thereby causing much waste and loss of time required
to piece the broken ends as is well understood. Previously to my invention fixed end
catchers or snarl hooks have been used for the purpose of intercepting the broken
ends but such fixed end catchers have been in the way when the bobbins have
been doffed and also end catchers have been applied to the same parts as the thread
guides so that the said catchers have of necessity been in position from the
commencement to the end of the filling of the bobbins. I have found that it is
advisable that the end catchers shall be some distance removed from their acting
positions during the starting and stopping of the frame. Accordingly I secure the
end catchers to a bar or rod which can be moved endwise or turned up or rocked
upon its axis so as to move the catchers out of the way before the frame is stopped
the catchers being moved back after the frame has got properly to work these
movements not interfering with the thread guides. In place of the catchers being
attached to a bar or rod they may be hinged to a rail or be mounted upon fulcera
or be mounted to slide or turn in bearings and be acted upon by a sliding or
rocking rod or bar or by other suitable parts which will cause the catchers to nove
in concert. Each end catcher may consist of a metal hook or of a piece of wire
or metal suitably bent or shaped so that when an end breaks it will wrap around
or engage with the catcher and be thereby prevented from coming into contact
with either of the adjacent ends.

page_text: Ends" in Ring Spinning and Doubling Frames.
I SAMUEL DRONSFIELD of the Windsor Mills, Lissadel Street, Pendleton, in the
County of Lancaster, Manager, 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 and accompanying drawings
My Invention relates to ring spinning and doubling machinery and has for its
object to prevent or lessen the formation of "snarls" and "lashed ends." When
an end of yarn breaks, it tends to fly outward and to come into contact or become
entangled with adjacent ends thereby causing much waste and the loss of time
required to piece the broken ends as is well understood. Previously to my invention
fixed end catchers or snarl hooks have been used for the purpose of intercepting
the broken ends but such fixed end catchers have been in the way when the
bobbins have been doffed and also end catchers have been applied to the same parts as
the thread guides, so that the said catchers have of necessity been in position from the
commencement to the end of the filling of the bobbins. I have found that it is
advisable that the end catchers shall be some distance removed from their acting
positions during the starting and stopping of the frame. Accordingly I secure the
end catchers to a bar or rod which can be moved end wise or turned up or rocked upon
its axis so as to move the catchers out of the way before the frame is stopped the
catchers being moved back after the frame has got properly to work these movements
not interfering with the thread guides. In place of the catchers being attached to a
bar or rod they may be hinged to a rail or be mounted upon fulcra or be mounted to
slide or turn in bearings and be acted upon by a sliding or rocking rod or bar or by
other suitable parts which will cause the catchers to move in concert. Each end
catcher may consist of a metal hook or of a piece of wire or metal suitably bent or
shaped so that when an an end breaks it will wrap around or engage with the catcher
and be thereby prevented from coming into contact with either of the adjacent ends.
To render my invention more clear I will now describe the same with reference to
the annexed sheet of drawings which illustrate the improvements.
Fig. 1 is a side elevation of a bobbin and a similar view of an end catcher or snarl
hook in its proper relative position when the frame is at work.
Fig. 2 is a front view of three bobbins each with its corresponding snarl hook.
Fig. 3 is a plan view of Fig. 2.
Figs. 4 and 5 illustrate a modification in the mode of operating the snarl hook.
Referring to Figs. 1 to 3 the bobbins are marked a, the ring rail band the
ring c. The bobbins are shown partly filled with yarn d the portion of yarn
extending from the ring traveller to the guide being marked d'. The hooked end
catchers e project from a bar f which can be slid to and fro in supports g by
means of a handle h. When the frame is at work, each bobbin a has its snarl hook e
in about the relative position shown in full lines in Figs. 1 to 3. When the snarl hook
is in this position, should the portion d¹ of the yarn break, the broken end comes at
once into contact with the snarl hook and is held thereby so that the formation of

page_text: lashed ends that is to say accidental entanglement with adjacent yarns is prevented.
The snarl hook holds the broken end till the "piecer up' "has rectified the damage.
When the frame is stopped at the end of the day or at meal hours or for other
purposes, the portion d' of the yarn usually becomes slacker so that in stopping and in
starting the yarn end balloons further from the bobbin than in ordinary circumstances.
It is therefore possible that at such times the yarn end though unbroken might be
caught by the snarl hook. To avoid this, when the frame is starting or stopping, I
move the snarl hooks away from the bobbins, for example I slide the bar f so as to
move the snarl hooks from the position shown in full lines to the position indicated in
dotted lines, that is to say between the bobbins instead of opposite to them. The snarl
hooks are thus kept out of the way of the slack yarns until the frame has come to a
stand when the frame is being stopped, or until the slack has been taken up after the
frame has been started. When the frame is again properly at work the bar f with
the snarl hooks is returned to the position shown in full lines. To facilitate the
operation of doffing the bobbins a, the bar i which carries the bar f, with the snarl
hooks, is hinged to a suitable part of the frame so that the bars i and with the snarl
hooks can be turned up away from the bobbins, leaving no obstacle in the way of
doffing. I do not however claim this hinging of the bar as it has been done prior to
the date of my present application for a patent.
Another mode of moving the snarl hooks out of the way of the bobbins is shown at
Figs. 4 and 5. Fig. 4 being a plan view of the snarl. hooks when in use and Fig. 5 a
similar view of the snarl hooks folded to one side so as to be out of the way. In this
arrangement the snarl hooks e are hinged at k to the bar fand in front of the bar fis
a sliding bar having perforations through which the hinged snarl hooks e protrude.
When in the position shown at Fig. 4 the snarl hooks are in proper working position,
but when the sliding bar is pulled in the direction of the arrow the snarl hooks are
folded down or to one side into the position shown at Fig. 5 so as to be out of
the way.
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) The general arrangement and combination of parts comprising the means for
preventing the formation of "snarls" and "lashed ends" in ring spinning and
doubling substantially as described and shown.
(2) As means for preventing "snarls" and "lashed ends" the "end catchers" or
"snarl books" e projecting from a sliding bar or rod and capable of being moved at
the required times towards and away from the bobbins, substantially as hereinbefore
described and shown.
(3) In apparatus for preventing "snarls" and "lashed ends" in ring spinning
and doubling, the end catchers or snarl hooks e hinged to a bar or other support
behind the bobbins and brought into working position or turned aside out of the way
by a movable bar, rod or connection acting upon tho said hinged snarl hooks
substantially as illustrated in Figs. 4 and 5 of the drawings and as hereinbefore
described.
