IMPROVEMENTS IN SHUTTLES OF LOOMS FOR WEAVING
Year: 1881

page_text: LETTERS PATENT to John Broadhead, of Huddersfield, in the County of
York, Desiguer and Loom Tuner, for an Invention of "IMPROVEMENTS IN
SHUTTLES OF LOOMS FOR WEAVING.*
PROVISIONAL SPECIFICATION left by the said John Broadhead at the
Office of the Commissioners of Patents on the 12th July 1881.
JOHN BROADHEAD, of Huddersfield, in the County of York, Design and Loom
Tuner. "IMPROVEMENTS IN SHUTTLES OF LOOMS FOR WEAVING."
This Invention relates to to the construction of iron or metallic shuttles, so as to
secure lightness, strength, and durability to improved runners for such shuttles,
and to dispense (in many cases) with the use of the "skewer so as to avoid the
waste of weft.
"
Shuttles according to this my Invention consist of a cast iron shell having rib or
ribs within which the weft end rests; other ribs give increased strength to the
shuttle. The shell may be cast, having open sides, these when necessarily closed
being closed by a plate, so that when the latter is worn it may be replaced by a
new one, and the shuttle is practically new again.
The runners are constructed of outer flanges enclosing a roller or runner made
from compressed paper or compressed cotton; the runners are connected to a blade
spring so as to provide against damage by shock and obstructions. For purpose of
admitting use of weft direct from cop without skewer, a cop is enclosed within a
case or box forming the interior, or being introduced to interior of the shuttle,
and over the cop closes a spring or other guard and holding fingers, which may
then be readily secured so as to hold the cop securely within the shuttle, and at
the same time permit free running of weft as required in the weaving.

JOHN BROADHEAD, of Huddersfield, in the County of York, Designer and Loom
Tuner, "IMPROVEMENTS IN SHUTTLES OF LOOмS FOR WEAVING."
This Invention relates to the construction of iron or metallic shuttles, so as to
secure lightness, strength, and durability to improved runners for such shuttles.
Shuttles according to this my Invention consist of a cast iron shell having rib or
ribs within which the weft end rests; other ribs give increased strength to the
shuttles. The shell may be cast, having open sides, these when necessarily closed
being closed by a plate, so that when the latter is worn it may be replaced by a
new one, and the shuttle is practically new again. The runners are constructed of
outer flanges enclosing a roller or runner made from compressed paper or compressed
cotton; the runners are connected to a blade spring so as to provide against damage
by shock and obstructions.
Such being the nature and object of this my said Invention, I will now proceed
to describe the same in detail, and in order that the Invention may be fully
understood we have hereunto annexed a Sheet of Drawings illustrating the
Invention.
DESCRIPTION OF THE DRAWINGS.
The shuttle frame 1 as shewn by the Drawings and sections is a kind of
ribwork 2 ensuring strength of the shuttle, and giving it at the same time the
greatest possible lightness.
The frame 1 of the shuttle may be cast or constructed so as to be full on the
back as well as on the front, or both sides can be closed with a separate plate 4, as
shewn in the cross sections A, B, C. This gives the shuttle greater durability, as
the plates 4 can be replaced when worn, and the frame 1 remains as good as new.
As the plates 4 are rivetted instead of screwed the shuttles are not liable to damage
the slay or piece being woven.
At the same time the shuttles may have open sides if required.
The shuttle tips or ends 6 of the frame can be made to screw or brazed in at the
end, as shewn in D and E.
The section F and side elevation G shew a shuttle the frame of which is
constructed of round bars or rods 7, 7. The rollers or wheels 8 are made either of
compressed cotton or of compressed paper secured with flanges 9 on each side, as
shewn in cross section H; at the same time I do not limit myself to the use of
wheels so made as wheels are not indispensable, as shewn at section L.
The section I shews how the blade springs 10, 10, acts on the frame 11, for
carrying the wheels 8, 8, the levers 11, 11, being capable of oscillating on the
studs or pins 13, 13; the blade springs 10, 10, may be of any desired form; it relieves
the shuttle in case of sudden shocks; in working the frame 11, 11, is held in
position by the projection 14 and tongue 15, dispensing with the use of screws or
pins, as heretofore.
At 16 is a blade spring which acts against the end of bobbin spindle a skewer 17
for keeping same in position. At section A is shewn how the weft tube or eye is
secured in position. The construction of shuttle, as above described, ensures great
strength, lightness, durability, dispenses with screws, and diminishes the number
of pins hereto required in the construction of shuttles.
Having thus fully described the nature of this my said Invention, together with

page_text: the manner in which the same is to be or may be performed or carried into
practical effect, I would have it understood that I claim as my Invention,-
Firstly. The construction of frame work of shuttles, as herein illustrated and
described.
Secondly. The application to and use of the blade springs 10, 10, in combination
with frame 11, 11, for purpose herein described and substantially as illustrated by
Drawings hereunto annexed.
Thirdly. The projections 14, 14, tongues 15, 15, acting on and in combination
with the frame work 11, 11, as and for the purpose herein fully described and
illustrated by Drawings.
Fourthly. The use of the spring 16 in combination with spindle 17 constructed
so as to act against the end of the said spindle 17, and as described and illustrated
by Drawings annexed.

In witness whereof, I, the said John Broadhead, have hereunto, set my hand
and seal this Fourth day of January, in the year of our Lord One thousand
eight hundred and eighty two.
JOHN BROADHEAD. (L.S.)
