IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1879

page_text: LETTERS PATENT to Alfred Haley, Spinner and Manufacturer, and Richard
Gill, Designer, both of Bradford, in the County of York, for the Iuvention
of "IMPROVEMENTS IN LOOMS FOR WEAVING."
PROVISIONAL SPECIFICATION left by the said Alfred Haley and Richard
Gill at the Office of the Commissioners of Patents on the Sth October 1879.
ALFRED HALEY, Spinner and Manufacturer, and RICHARD GILL, Designer, both
of Bradford, in the County of York. "IMPROVEMENTS IN LOOMS FOR WEAVING.”
The object of this our Invention is the embroidering of pieces during the process
of weaving, the mechanism employed for inserting and receiving the inlerlocking
the embroidering thread or threads with the warp and weft being operated from
going parts of a loom as ordinary constructed.
Apparatus for purpose aforesaid, constructed according to this our Invention,
comprises a series of needles carried by a supporting and traversing bar; the
embroidery threads are conveyed to and through the eye of the needles; the needle
bar is operated by levers and tappet from the tappet shaft, so as to insert the
embroidery thread amongst the warp threads, forming along with the latter an
open shed for the passage of the shuttle; the needles resume their original position
before the beat up, whereon a rod in front of the needles and over which the
embroidering threads are passed is raised by lever and tappet so as to take up the
slack of the threads. The traverse of the needle bar and needles is effected by
means of a worm and catch wheel, the latter being turned tooth by tooth, first in
one direction, then in the other (according to the design or pattern being
embroidered), by means of over and under fingers which alternately (as determined
by card mechanism) act on the catch wheel referred to.
In the embroidering of diamond or regular figures it is preferable to use a
duplicate set of needles and needle bar, these being operated in like manner by
right and left worms to the one already described, and in the embroidery of
disconnected figures or patterns the lever and tappet motion for opening the
needles is thrown out of gear from the pattern mechanism until the repeat of the
figures.

page_text: At 1, 1, 1, are needles carried by bar 2 and arms 3, 3; the bosses of the latter
are on the worm shaft 4, the worms being right and left hand screws so as to
give lateral traverse to each half of the needles in opposite direction, whereby so
as to produce the two sides of diamond or other like figures; the vertical motion
of the needles so as to bring down the embroydering threads 5 and insert them
amongst the warp threads is obtained by means of lever 6, operated by tappet 7
from the tappet shaft 8, link 9, connecting rod 10, lever 11, and arms 3, 3.
When the shuttle has passed through the shed the embroydering threads are
drawn up and the slack taken up by means of the cross rod 12, which rod receives
a vertical motion from the arms 13 on rod 14, the latter being operated by
lever 15, connecting rod 16, lever 17 on fulcrum 18, the lever 17 receiving
motion by link 19 through the lever 20 operated by tappet 21 from the shaft 8.
The worm shaft 4 is operated by means of the fingers 22, 22, as follows:-When
the slay recedes for formation of the shed the toothed wheel 23 will come in contact
with one or the other of the fingers 22, the latter being connected by cords 24, 24,

page_text: to the jacquard or other pattern mechanism, whereby will be determined which of
the two fingers shall act upon the wheel 23 so as to turn the shaft 4 in one direction
or another. At Figs. 3, 4, (Sheet 2) is plan and elevation of part of double needle
bar 2, 2, and double set of needles 1, 1, the arrangement and operating the bars and
needles being by double worms, and as already described in reference to the use of
a single set of needles.
In the embroydering of diamond or regular figures or patterns the lever and
tappet motion for operating the needles is thrown out of gear by means of the
catch lever 25 (see Figs. 5, 6, and 7) carried by frame 26 bolted to the cross rail 27;
the pattern cords 28, 29, pull the tumbler catch so as to turn the said catch 25
upwards, whereon the catch lever 25 will fall back, clearing its hooked end from
the stud 30, the embroydering apparatus is then out of use until the pattern
mechanism, by a pull on cord 28', shall again bring down tumbler catch 25, which
at the same time forces lever 25 into position that its hooked end again engages
the stud 30 and the embroydering apparatus comes into operation.
Having thus fully described the nature and particulars of this our said Invention,
together with the manner in which the same is to be or may be performed or
carried into practical operation, we would have it understood that what we claim
as our Invention is,―
Firstly. The use of the shaft 4 (having right and left handed worins thereon)
combined with and carrying and traversing in opposite direction the bar and
needles, for purpose described.
Secondly. The use of the fingers 22, 22, in combination with the wheel 23 for
operating the worm shaft 4 and needles, as described and as illustrated.
Thirdly. The use of the rod 12 in combination with the levers and tappet for
operating the same, for purpose described and illustrated by Drawings.
In witness whereof, I, the said Richard Gill, for and on behalf of myself and
the aforesaid Alfred Haley, have hereunto set my hand and seal, this Third
day of April, in the year of our Lord One thousand eight hundred and
eighty
