Year: 1855

page_text: LETTERS PATENT to William Langshaw, of Eagley, near Bolton, in the
County of Lancaster, and George and William Jelley, of Leicester, for
the Invention of "IMPROVEMENTS IN MACHINERY FOR MANUFACTURING FANCY
FABRICS WITH BOTH SIDES ALIKE."
Sealed the 20th November 1855, and dated the 29th May 1855.
PROVISIONAL SPECIFICATION left by the said William Langshaw and
George and William Jelley at the Office of the Commissioners of Patents,
with their Petition, on the 29th May 1855.
We, WILLIAM LANGSHAW, of Eagley, near Bolton, in the County of
Lancaster, and GEORGE and WILLIAM JELLEY, of Leicester, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR MANU-
FACTURING FANCY FABRICS WITH BOTH SIDES ALIKE" to be as follows:-
Our Invention consists of using two warps and a number of rolling double-
booked needle bars which revolve with a cam or eccentric motion, the said
needles being so arranged, that the rolling bars passing through the warp
threads with the material on the hooks to form the required pattern, which
material is liberated by means of releiving pins or wires, and thus the desired
pattern is made the same on both sides of the material.

by the said William Langshaw and George and William Jelley in the
Great Seal Patent Office on the 28th November 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
LANGSHAW of Eagley, near Bolton, in the County of Lancaster, and GEORGE
and WILLIAM JELLEY, of Leicester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Royal
Letters Patent, bearing date the Twenty-ninth day of May, in the year of our
Lord One thousand eight hundred and fifty-five, in the eighteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said William Langshaw & George and William Jelley, Her special
licence that we, the said William Langshaw & George and William Jelley,
our executors, administrators, and assigns, or such others as we, the said
William Langshaw & George and William Jelley, our executors, adminis-
trators, and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United Kingdoni
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN MACHINERY FOR MANUFACTURING FANCY FABRICS
WITH BOTH SIDES ALIKE," upon the condition (amongst others) that we, the
said William Langshaw & George and William Jelley, by an instrument in
writing under our hands and seals, or under the haud and seal of one of us,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Royal Letters Patent.
NOW KNOW YE, that I, the said William Langshaw, for and on behalf
of myself and the said George and William Jelley, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
Our Invention consists of using two warps, and fixing to a bar or shaft a
number of double-hooked needles, which are made to roll or perform a portion
of a revolution alternately by means of the action of a cam or eccentric. The
said hooked needles are so arranged, that as they pass through the warp threads
or material, the hooks in conjunction with the action of one or more guides
form the material both sides alike, according to the required pattern. The
material is both regulated and liberated by means of relieving pins or wires.

page_text: By employing cams, pattern wheels, or any of the well-known methods of giving
varied motion to the guides, an indefinite diversity of patterns can be made.
These improvements will be clearly understood by reference to the accom-
panying Sheet of Drawings, in which the letters of reference refer to the same
parts in all the Figures.
Fig. 1 is a front elevation of a double warp machine, having our double-
hooked rolling needles and the arrangement for working them attached;
Fig. 2 is an end view of the same; Fig. 3 is a view of the other end, with part
of the frame broken, in order to shew the working parts; Figs. 4 and 5 are
detached views of one of the needles; and Figs. 6 and 7 are detached sections
of the bar, needle, guides, and relieving or regulating pins, drawn to an
enlarged scale.

a chain wheel k, which has an alternate rolling or concentric motion given to it
by the eccentric e moving the L or bell-crank levers and chain m, which is
made fast at one part to the chain wheel k. The guides are shewn at n
attached to the bars o, having the pivots p at their ends of such a length as to
enable them to move transversely in their bearings 9. The bars and guides are
made to vibrate by being connected to the shafts », furnished with the levers s,
to which are attached the upper ends of the connecting rods t, their other ends
being connected to the bell-crank levers u, alternate motion being given by
means of the cam 9. and transmitted to the guides. The bell-crank levers u

are kept up to the cam g by means of the springs v.
relieving pins are shewn at w; they are raised by the levers a on the shafts y,
to which motion is given by the action of the cam f, the levers a', and the
connecting rods b'. Lateral motion is given to the guides and pins by their
bars or frames being connected by the rods c¹ to the levers d', acted upon. by.
the cams or pattern wheels e¹ upon the shaft f', to which motion is given by
the ratchet g', acting upon the ratchet wheel ' made fast to the shaft f¹; the
the
ratchet is connected to the lever j', and is moved by the double cam k¹;
counter movement of the bars being effected by springs in the usual manner.
The detached view at Fig. 6 shows the positions of the needles, guides, and
pins when the machine is not in motion. Fig. 7 shews their positions at one
extremity of their course, the other extremity being shewn by the dotted lines.
The operation of the double-booked needle is as follows:-A warp is slightly
shifted laterally, so that it can be seized by one of the hooks of the needle, then

page_text: be carried partially round and held upon the trunk or stem of the said medle,
at which time the opposite regulating pin performs its task of shifting its
corresponding warp, so that the other hook can seize it and form a loop, which
also passes on to the stem or trunk of the needle, the former loop at the same
time passing off. The loops are alternately relieved or rolled off the needle by
the combined action of the peculiar form of the needle below the hooks, and
the rolling or concentric motion imparted to it.
Having thus fully described the nature and particulars of our said Invention,
and the manner of carrying the same into practical effect, I desire it to be
distinctly understood that we do not confine ourselves to the exact details and
arrangement of apparatus herein set forth, as such may be varied or modified
without departing from the principle thereof; but we claim,-
Firstly, a needle with double hooks upon one end of the trunk or stem,
having the lower part so formed as to throw off the loops when required.
Secondly, the use or employment of regulating or relieving pins for the
purpose of assisting in the formation of the loops, and the general arrangement
of the several parts, as herein described, and illustrated in the accompanying
Sheet of Drawings.
In witness whereof, I, the said William Langshaw, for and on behalf of
myself and the said George and William Jelley, have hereunto set my
hand and seal, this Twenty-fourth day of November, One thousand
eight hundred and fifty-five.
WILLIAM LANGSHAW. (Ls.)
