Year: 1842

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
Goos, of Manchester, in the County of Lancaster, Jacquard Machine Maker,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-third day of May, in the fifth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Frederick
Goos, Her especial licence, full power, sole privilege and authority, that I,.
the said Frederick Goos, my executors, administrators, and assigns, and such
others as I, the said Frederick Goos, my executors, administrators, and assigns,
should agree with, and no other, from time to time and at all times during
the term of years therein expressed, should and lawfully might make, use,
exercise, and vend, within England and Wales, and the Town of Berwick-
upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN THE JACQUARD MA-
CHINE OR APPARATUS TO BE USED OR EMPLOYED IN LOOMS FOR WEAVING;" in which
Letters Patent is contained a proviso, that I, the said Frederick Goos, shall
cause a particular description of the nature of my said Invention, and in what
manner the same is to be performed, to be enrolled in Her Majesty's High
Court of Chancery within six calendar months next and immediately after the
date of the said in part recited Letters Patent; as in and by the same, reference
being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Frederick Goos, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, is particularly described

page_text: and ascertained in and by the Drawings hereto annexed, and the following
explanation thereof, that is to say :-
My improvements in the jacquard machine or apparatus consist in a
novel construction or arrangement of the well-known piece of mechanism
called the "jacquard," whereby the figure or fancy work is now commonly
wrought in looms. By my improved construction of the jacquard machine,
and also by the combination of certain novel parts now introduced, this
apparatus is rendered much more efficient and true in its operation, and
less liable to injury arising from any accidental derangement of its working
parts.
Such being the nature of my said Invention, I proceed to describe the
manner in which the same is to be performed. Although the common
jacquard machine or apparatus is well known and understood by persons
conversant with weaving, I have thought it necessary in the first place to
describe and represent that apparatus as now commonly employed, in order
that my improved construction of the jacquard may be more apparent, and
its novel arrangement more distinctly represented, and have also attached to
these Presents two Sheets of Drawings marked with figures and letters
referred to in the following description of the apparatus, similar letters being
placed upon corresponding parts of the mechanism in all the Figures.
In Sheet 1, Fig. 1 represents a transverse section taken vertically through
about the middle of an ordinary jacquard machine or apparatus, and drawn
upon the full scale. It is shewn in outline only, in order to distinguish it
(being entirely old and in common use) from my improved construction and
arrangement of the apparatus, which is also shewn in transverse section upon
the full scale at Fig. 1 in Sheet 2; Fig. 2 being a front view of the same,
shewn as broken in the centre, the width of the machine depending upon
the number of rows of needles required. The framework of the jacquard
is shewn at a, a, a, a, and is usually attached to the upper part of the
loom framing; bis the top piece or cross head which carries the " "griff"
or grate c, c, c, c, for lifting the hooks or wires d, d, d, d, attached to the
stringing e, e, e, e. f, f, represents the rack teeth upon the "griff," and
g, g, the toothed segment for working the links h, h, attached to the card
cylinder" i, i, in order to slide the same in and out as required; the
needles are shewn at k, k, k, k, supported by the front board l, l, at one
end, and by the wires m, m, in the back rack at the other end; behind
these needles is the spring box n, n, containing the springs 0, 0, 0, 0, which
keep the needles up against the pattern card p, p; the latches for turning the
cylinder to advance the cards are shewn at q, q*, the latter being only used to
66

page_text: reverse the cylinder when any false picks are made. r, r, is the holdfast
which presses upon the "lantern" 8, 8, upon the end of the cylinder and keeps
it firm or square after every turn or pick; the hooked wires bed in the bottom
plate or board t, t, and are kept even or square in their action by the guide
rails u, u, bearing upon their lower extremities. The action of this common
jacquard machine is as follows:-Supposing the pattern cards p, p, perforated
agreeably to the design intended to be wrought extending over the cylinder i,
and held thereon by the pegs j passing between that and the front board l, l,
those needles k, k, which pass through the perforations in the cards p are not
disturbed, but those opposite to which blank spaces are presented by the card
are thus pushed back by the card, and as the eye of the needle embraces the
vertical hooks or wires d, d, it throws those wires out of the perpendicular,
when the " 'griff" or grate c, c, is caused to. ascend by any suitable motion
communicated from the working parts of the loom to the cross head b, and
thus lift those needles that are left in the perpendicular position, escaping those
which have been thrown out of it by the card, and consequently pull up the
strings e, e, connected to the warp threads and work the pattern in the cloth,.
as is well understood by the practical weaver.
Such being the general and leading features of the jacquard machine now
in common use, the improved construction and arrangement I claim as my
Invention will be immediately understood by reference to Sheet 2, where the
whole machine as now improved is represented. Similar letters will be found
upon corresponding parts of the apparatus as in that just described, and I
will now explain the features of novelty or improvement by which the
whole of the operations are performed in a more perfect and efficient manner,
and the several parts secured from any accidental derangement, which so fre-
quently occurs in common jacquard machines. In the first place, I introduce
what I term a press board A, indented, and remove the cylinder i from its usual
situation; by this contrivance the cards are presented to the front board 1, 1,
with more certainty, and any accidental breakage prevented, should the
"cylinder" not be turned entirely round as the card advances; the cylinder is
now made plain, or not indented, and employed merely for the purpose of
advancing the cards, the press board holding the cards to act upon the needles.
I also place pegs z (see Fig. 1, Sheet 2) upon the front board 7, as well as the
cylinder, in order to ensure the more certain presentation of the cards to the
needles. I also reverse the position of the holdfast upon the "lantern 8,
and employ the rods B, B, and springs C, C, to act upon the "lantern" from
below, as shewn, and form the bottom of such holdfast bevilled, which further
secures the correct position of the card cylinder, as it is termed. It will also
"

page_text: be seen in Fig. 2 that I employ an independent "lantern" S, S, outside the
framing, with a flange to guide thé latches q, qx, these latches being in one
piece instead of two. Another improvement in this part of the apparatus is
made by having the cylinder guide frame D open at the end, in order that the
cylinder and press board, with their carriage, may be readily removed to put
the cards over. The bottom rail D* of this guide frame is made adjustable by
bolts and slots, that the guide may be always kept true, and the carriage and
slide H, H, of the cylinder is kept firm by the cross rod Q, Q. By this improved
arrangement of the cylinder carriage and slide, I am enabled to place the slide
R inside the guide rails D, D, instead of outside as heretofore. Additional hold-
fasts E, E, are placed at the top of the cards to press them on the cylinder,
which are not weighted by springs, but rise and fall by their own gravity, their
guide rods sliding in holes in the cross rail F. I have introduced two rods
G, G, with springs attached, having flat heads or discs countersunk in the front
board, for the purpose of pushing the card off the needles k, k, and the pegs z,
after they have acted on the needles or springs, may be placed in the front
board, which shall have a similar effect when the press board recedes. I also
make the bottom guides I, I, of iron plate instead of the wooden rails u, u, and
have slots pierced in the plate for the hooks d, d, which is connected by the
frame K, K, to the "griff," and rises and falls with it, sliding on the guidé
rods L, L, and I introduce a series of wires M, M, under this plate, to prevent
the hooks being displaced. A most important feature in my Invention is
making the tail ends of the hooked wires d, d, d, d, so long that they shall
extend upwards above the top row of needles k, k, k; these tail ends then bear-
ing against a series of horizontal wires N, N, N, will act as springs upon the
needles, and entirely supersede the use of the spring box n, n, and the spiral
springs o, o. I would here remark that these wires N, N, may be placed
horizontally, as drawn, or they may be placed in either of the diagonal positions,
as drawn in red, when they will possess the further advantage of supporting the
needles.
Finally, a further improvement in the jacquard machine consists in sub-
stituting the disc o, o, having circular studs or teeth P, P, upon its side, to
work into the rack f upon the "griff," instead of the toothed segment g, g, as
such arrangement will facilitate the gearing; and I also employ an im-
proved mode of fastening the segment plate to the links h, as clearly shewn
in the detached Fig. 3.
Having now particularly described the nature of my Invention of im-
provements in the jacquard machine or apparatus, and the manner in which
the same is to be performed, I desire it to be understood that I do not claim.

page_text: any of the well-known parts (as hitherto employed), which are here shewn and
described only for the purpose of illustrating my improvements. But I do
claim the improved arrangement and construction of the apparatus, as exhibited
in Sheet 2 of the Drawings, and herein set forth and described, and most par-
ticularly as relates to the press board, the holdfasts, the bottom plate and
wires, the tail ends of the hooks extending above the level of the top needles,
the springs for pushing the cards off the needles or front board, the placing of
the cylinder slide or carriage inside their guide rails instead of outside, the
guide rods L and cross rods Q, the circular teeth for working in the rack upon
the "griff," and the improved [stud or fastening for the links shewn in Fig. 3.
In witness whereof, I, the said Frederick Goos, have hereunto set my
hand and seal, the Twenty-second day of November, in the year of
our Lord One thousand eight hundred and forty-two.
