Year: 1872

page_text: LETTERS PATENT to James Crabtree, of Liversedge, in the County of
York, Loom Tuner, for the Invention of "A NEW OR IMPROVED
APPARATUS POR AND MEANS OF WINDING WEPT ON THE PINS OF SHUTTLES OF
LOOMS FOR WEAVING, SO AS TO DISPENSE WITH THE USE OF BOBBINS OR SPOOL
TUBES."
Sealed the 28th March 1873, and dated the 23rd October 1872.
PROVISIONAL SPECIFICATION left by the said James Crabtree at the
Office of the Commissioners of Patents, with his Petition, on the
23rd October 1872.
I, JAMES CRABTREE, of Liversedge, in the County of York, Loom
Tuner, do hereby declare the nature of the said Invention for "A
NEW OR IMPROVED APPARATUS FOR AND MEANS OF WINDING WEFT ON THE PINS
OF SHUTTLES OF LOOMS FOR WEAVING, SO AS TO DISPENSE WITH THE USE OF BOBBINS
OR SPOOL TUBES," to be as follows:-

page_text: shuttle of looms for weaving, and so provide for an increased quantity
of weft within such shuttles, and economize material and time. I employ
a winding frame having a number of revolving spindles driven by
grooved pulleys, the top of each spindle being recessed to receive the
point of the shuttle pin, which is thus caused to revolve, and a conical
cup or cap directs the weft when being wound on the shuttle pin. A
weight on the end of a stud or spindle passed through an upper rail
bears on the top of each shuttle pin for the purpose of steadying and
holding the same in position. Or a tube having a slit formed vertically
therein may be employed, the shuttle pin being caused to revolve therein
by means above described, and a disc or collar fitting the interior of the
tube and having a hole formed in the centre thereof, so that the said
disc or collar steadies the shuttle pin when revolving, and whilst being
filled with weft within the said tube.
the
Another arrangement of apparatus for this purpose consists in the
employment of revolving spindles having a key fixed thereto, which
enters a key bed cut in the driving pulleys of the said spindles,
shuttle pins in this case being inverted, and the end being inserted in
the recessed end of the spindle as above described. The conical cup or
cap directs the weft on to the shuttle pin, the latter as it fills
gradually raises or lifts the spindle until the key therein is clear of the
key bed cut in the grooved driving pulley, which will thus ccaso to
revolve. By the time this is accomplished the shuttle pin will be full of
weft, or the "quill" formed thereon, and the shuttle pin and "quill"
are ready for removal. This arrangement admits of the use of round
taper shuttle pins.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Crabtree in the Great Seal Patent Office
on the 23rd April 1878.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
CRABTREE, of Liversedge, in the County of York, Loom Tuner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of October, in the

page_text: be employed, the shuttle pin being caused to revolve therein by means
above described, and a disc or collar, fitting the interior of the tube,
and having a hole formed in the centre thereof, so that the said disc or
collar steadies the shuttle pin when revolving, and whilst being filled
with weft within the said tube.
Another arrangement of apparatus for this purpose consists in the
employment of revolving spindles having a key fixed thereto, which
enters a key bed cut in the driving pulleys of the said spindles, the
shuttle pins in this case being inverted, and the end being inserted in
the recessed end of the spindle as above described. The conical cup or
cap directs the weft on to the shuttle pin, the latter as it fills graduaally
raises or lifts the spindle until the key therein is clear of the key bed cut
in the grooved driving pulley, whereon the spindle will cease to revolve.
By the time this is accomplished the shuttle pin will be full of weft, or
the "quill" formed thereon and the shuttle pin and " quill" are ready
for removal. This arrangement admits of the use of round taper shuttle
pins.
Such being the nature of the said Invention, I will now proceed to
to explain the manner in which the same is performed or put into
practice by the aid of the accompaning Sheet of Drawings, wherein
Fig. 1 shews a front elevation; and Fig. 2 a cross section of apparatus
constructed in accordance with the latter arrangement, which I find to
answer best. A are the revolving spindles, having keys or feathers a
which fit in beds cut in the driving pulleys B, which admit the spindles
to slide therein, the said pulleys being placed betwixt two rails C and C',
through which the said spindles pass, and are steadied by as well as by
a top rail 0. The portable shuttle pin D is inserted in the end of the
spindle A, and passes through the cup E where the weft is wound on
the said pin, and as it fills or more quantity becomes wound thereon
the pin and spindle rise until the key or feather passes through the
pulley, when the spindle ceases to rotate, and consequently to wind any
more weft on the pin.
Having thus fully described the nature and particulars of my said

page_text: herein-described and illustrated.
In witness whereof, I, the said James Crabtree, have hereunto set
my hand and scal, this Twenty-first day of April, in the year of
our Lord One thousand eight hundred and seventy-three.
Signed, sealed, and delivered by the
within-named James Crabtree, in
