Improvements in Means for Holding Warp-yarns for Drawing in
Purposes.
I, CHARLES DEWICK LANNING, of No. 95, Milk Street, in the City of Boston,
State of Massachusetts, United States of America, Lawyer, 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 the controlling of the ends of the warp threads
or yarns of a warp prior to the operation of drawing in, so that the warp threads
may be manipulated in the most advantageous manner.
رو
It is known by those skilled in the art that warp threads or yarns when sized,
dried, or finished in the slasher or equivalent machine are spaced or arranged to
all intents and purposes in an even and orderly manner, and that after a "warp
is detached the ends become more or less tangled or disarranged before they are
drawn in preparatory to weaving, so that the difficulty of the drawing-in
process is much aggravated.
"
وو
In the carrying out of the present invention the purpose of keeping the warp
threads in the same substantially even and orderly position after they leave the
slasher or dresser that they had before being cut out, has been the chief thing
kept in mind. This idea has been worked upon with the result of developing
means whereby the substantial regularity of the warp threads in the dressing
machine is maintained when the warp is removed therefrom, for the reason that
whether the warp threads are drawn in by hand or machinery, the work is greatly
facilitated by having the said warp threads supported, spaced, or positioned in
an orderly way.
To these ends my invention consists, primarily of a clamp comprising two
members adapted to grasp the warp threads, on opposite sides of the same, and
hold them in substantially the position that they were in or may have had just
before being cut from the slasher. I have contemplated the use of two clamps,
though one may subserve my purpose in some if not in most cases. Again, while
I have contrived various forms of clamps and cooperating means I have thought
it necessary to describe and show only such form or forms as will give a clear
understanding of the construction and mode of operation of the improvement. .
Reference is to be had to the annexed drawings and to the letters and figures
marked thereon, forming a part of this specification, the same letters designating
the same parts or features, as the case may be, wherever they, occur.
Of the drawings-
Figure 1 is a perspective view of the invention in an operative form in which
it may be constructed
Fig. 2 is a front view showing two of the clamps attached to the worn come

page_text: with the latter in the position they will have after having been dressed and
finished in the slasher when my improvement is applied thereto.
Fig. 3 is a cross sectional view of a modified form of a pair of the clamping
members entering into the invention.
In the drawings-
a a designate two bars which may be of metal or any other suitable material. The
said bars are arranged so that they may be placed on opposite sides of the warp
threads or yarns of a warp and clamped thereon by any suitable means, and so
as not to disturb the position of the warps. One efficient way of securing the
clamping bars together is shown in the drawings, wherein the bars are illustrated
as hinged together at one end, as at,b, and one bar provided at the other end
with a buckling device,'e; adapted to be slipped over the adjacent end of the
other bar and so effect a buckling of the two ends together and a clamping of
the bars upon the warp threads, holding the latter in exactly the position they
were in prior to securing the clamps thereon..
In some instances where it is desired to hold the warp threads quite firmly
the bars; a, may be provided on their inner faces with a lining, d, of felt
or other suitable material; but in some instances, at least, this felt lining will
be dispensed with.
In some cases, both in hand and machine drawing, I may use pairs of clamps
in such a way as to hold the warp threads in particular position between two
points or lines, so as to enable the said warp threads to be operated upon between
the said points or lines. In this case I may construct each clamp as before
described, employing a removable rule-jointed link, e, between them at their
ends, in order to stretch the warp threads evenly between the clamps, and hold
them in exact order, as well also as to subserve some other purposes.
In case it should be desired to hold the warp threads more securely than they
would be held by merely the felt-lined bars, I may provide one of the bars, as
the bar a', with a groove, and the opposite bar with a corresponding tongue, as
shown in Fig. 3, so that the warp threads caught between the bars, being bent
over angles, will be held more firmly than when held between smoother or more
regular surfaces.
As the object is to clasp and hold the warp threads in the same orderly manner
that they were in when in the slasher, and. to use them when so held in the opera-
tion of drawing-in, whether by hand or machinery, clamps of any form when
adapted, as described, to accomplish these ends will fall within the scope of my
invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim, is:
1. Clamps adapted to extend across a warp from side to side and engage the
warp threads on opposite sides and hold them in the position in which they may
happen to be in when engaged by the clamps, and means for connecting the ends
of the clamps.
2. Clamps adapted to extend across a warp from side to side and engage the
warp threads on opposite sides and hold them in the position in which they may
happen to be in when engaged by the clamps, and means for connecting the
ends of the clamps, the said clamps consisting of bars lined with felt or equiva-
lent material.
3. A pair of clamps adapted to extend across a warp from side to side and
engage the warp, threads on opposite sides and hold them in the position in which
they may happen to be in when engaged by the clamps, and, on different lines,
and means for connecting the ends of the clamps.
I' 4. A pair of clamps adapted to extend across a warp from side to side and
engage the warp threads on opposite sides and hold them in the position in which

and means for connecting the ends of the clamps, combined with removable
stretching links attached to the clamps..
