I, DAVID MCGREGOR of 21 North Tay Street, Dundee, in the County of Forfar,
North Britain, Shuttle Maker do hereby declare the nature of this invention to be
as follows:
This Invention, which relates to improvements in shuttles for holding the cops
used in weaving operations, has for its object to enable a greater quantity of yarn to
be contained in the shuttles than hitherto and also to produce a nearer equality of drag
of the yarn in both directions than has been previously obtained, whereby the objection
to a loose and tight selvedge being the result of drawing the yarn from one end of
the shuttle as hitherto is abolished. The obtainment of increased space within the
shuttle for holding the cop is achieved by the employment of a thin bridge of metal
in place of the wooden bridges hitherto in use and as the drag ordinarily employed
at the end of the shuttle is under this Invention removed to the centre of one side
thereof, the space usually occupied by such drag becomes available for the introduction
of a cop of greater length. The eye through which the yarn is drawn from the cop
is at one end of the shuttle and from it a groove leads down to the centre of one side
of the shuttle where drag pins or a second eye or a spring drag is or are located.
A further feature of the improvement in cop shuttles consists in the making of
the cop point springs with two jaws both of which are serrated, perforated or barbed
instead of one only of such being serrated, perforated or barbed as hitherto.

page_text: I, DAVID MCGREGOR of 21 North Tay Street, Dundee, in the County of Forfar,
North Britain, Shuttle Maker du 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:-
My Invention, which relates to improvements in shuttles for holding the cops used
in weaving operations, has for its object to enable a greater quantity of yarn to be
contained in the shuttles than hitherto and also to produce a nearer equality of drag
of the yarn in both directions than has been previously obtained, whereby the
objection to a loose and tight selvedge being the result of drawing the yarn from one
end of the shuttle as hitherto is practically abolished. The obtainment of increased
space within the shuttles for holding the cop is achieved by the employment of a
thin bridge of metal attached to the cover in place of the wooden bridge hitherto
in use and as the drag ordinarily employed at the end of the shuttle is under this
Invention removed to the centre of one side thereof, the space usually occupied by
such drag becomes available for the introduction of a cop of greater length. The
eye through which the yarn is drawn from the cop is at one end of the shuttle and
from it a groove leads down to the centre of one side of the shuttle where drag pins
or a second eye or a spring drag is or are located.
A further feature of the improvement in cop shuttles consists in the making of the
cop point springs with two jaws both of which are serrated, perforated or barbed
instead of one only of such being serrated, perforated or barbed.
In order that my said Invention may be properly understood and readily carried
into effect, I will now proceed to describe the drawings hereunto annexed.
Figure 1, is a plan of my improved shuttle.
Figure 2, is a longitudinal vertical section of the same on the line A, B, Figure 1.
Figure 3, is a plan and part horizontal section of my improved shuttle with a drag
eye placed in the centre of one side as hereinafter described.
Figure 4, is a longitudinal vertical section on the line E, F.
Figure 5, is a transverse section of the same through C, D, Figure 4.
In the cop shuttle represented in the annexed drawings, the body of the shuttle is
marked A, and is constructed of wood in the ordinary manner in the ends of which
the ordinary driving tips marked B are fixed in the usual manner. The shuttle is
hollowed out as usual to contain the cop, the said hollow being much longer than those
now in use on account of the metal bridge piece marked C, being used in place of
the wooden bridge piece as hitherto. The bridge piece marked C, according to my
Invention is secured to the hinged lid or cover D, and falls into corresponding
recesses E, formed on the upper part of the body A, as shewn.
The cop cover D, is serrated, perforated or barbed as shewn to keep the cop in its
proper working position and the sides of the shuttle are roughened or corrugated in
the usual manner as represented more particularly in Figures 2 and +.

page_text: The drag arrangement of my improved cop shuttle is situated in the centre of one
side of the shuttle instead of one end of and within the shuttle as heretofore. The
yarn is drawn from the cop within the shuttle through the drag eye or "pigs eye" F,
situated at one end of the shuttle and passes along the groove G, in one side of the
shuttle as shewn in dotted lines Figures 1 and 2, and thence across the drag pins
marked H, and H¹, over and partly around one of which namely the pin marked H¹,
the yarn passes when the shuttle is moving in the direction indicated by the upper
arrow X, and across both of which pins marked H and H', the yarn passes when the
shuttle is travelling in the direction of the lower arrow marked Y.
As an alternative method, I sometimes use at the centre of one side of the shuttle
a drag eye or "pigs eye" marked J, as shewn in Figures 3 and 4 in place of the
drag pins marked H and H' as shewn in Figures 1 and 2, such arrangement will give
a very regular and equal drag and is in some cases preferred.
The cop point springs K, are constructed with two jaws which are both serrated
perforated or barbed as shewn.
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 :-
First. Cop shuttles with the drag arrangements external to the interior of the
shuttle whereby space is obtained for the admission into the shuttle of a longer cop
than hitherto substantially as herein described and shown by the drawings.
Second. The constructing of cop shuttles with a groove at one side leading from
the pigs eye or drag eye to drag pins or a second " pigs eye" or drag eye
situated at the centre of the same side of the shuttle substantially as herein described
and shewn by the accompanying drawings.
Third. The constructing of the cover of shuttles with a metallic bridge C, attached
to or forming part of the said cover substantially as herein described and shewn by
the accompanying drawings.
Fourth. The constructing of the cop point spring with both portions thereof
perforated, barbed or serrated substantially as herein described and shewn by the
accompanying drawings.
