IMPROVEMENTS IN JACQUARD LOOMS
Year: 1863

page_text: LETTERS PATENT to Abraham Haley, of Frome, in the County of
Somerset, Machinist, for the Invention of "IMPROVEMENTS IN JACQUARD
LOOMS."
Sealed the 24th November 1863, and dated the 26th May 1863.
PROVISIONAL SPECIFICATION left by the said Abraham Haley at the
Office of the Commissioners of Patents, with his Petition, on the
26th May 1863.
I, ABRAHAM HALEY, of Frome, in the County of Somerset, Machinist,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
JACQUARD LOOмs," to be as follows:-
My Invention consists, first, in the employment in jacquard looms of 'a
vibrating frame in which a cylinder is free to revolve, having motion com-
municated to it by toothed wheels from the crank shaft of the loom. A star
wheel produces an intermittent motion or "dwell" at each revolution, during
which time the frame and cylinder are caused to rise through a lever, and at
the same time to strike off the hooks to which the harness is connected by
strings. I place "lags" with pegs round the cylinder, which are inserted in
apertures in the "lags" in such manner as to produce the desired pattern' on
the cloth or other fabric under manufacture. I use crank levers between the
"lags" and pegs and the ends of the needles. The levers are kept in position
by "grids," one at each end of the crank levers.
My Invention consists, secondly, in the employment in jacquard looms of an
endless chain composed of pins carrying small pulleys arranged according to
the pattern to be produced. The chains may be adapted to any number of

page_text: harness or "number to the round." The chain revolves on the cylinder or
band before described, which is mounted on a vibrating frame, and in such
manner as to rise and fall through the agency of a lever at each revolution of
the loom. When I use the chain and pulleys the cylinder is made with grooves
the same pitch as the pulleys on the chain, and the grooves guide the pulleys
in their places when striking the levers.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Abraham Haley in the Great Seal Patent Office on the
26th November 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ABRAHAM
HALEY, of Frome, in the County of Somerset, Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of May, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Abraham Haley, Her special licence that I, the said Abraham Haley,
my executors, administrators, and assigns, or such others as I, the said Abraham
Haley, my executors, administrators, 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 Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN JACQUARD LOOMS,"
upon the condition (amongst others) that I, the said Abraham Haley, my exe-
cutors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, 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 Letters Patent.
NOW KNOW YE, that I, the said Abraham Haley, do hereby declare the
nature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof, reference being had to the Drawings hereunto annexed, that is
to say:-
My Invention consists, first, in the employment in jacquard looms of a
vibrating frame in which a cylinder is free to revolve, having motion com-

page_text: municated to it by toothed wheels from the crank shaft of the loom. A star
wheel produces an intermittent motion or "dwell" at each revolution, during
which time the frame and cylinder are caused to rise through a lever, and at
the same time to strike off the hooks to which the harness is connected
by strings. I place "lags" with pegs round the cylinder, which are
inserted in apertures in the "lags" in such manner as to produce the
desired pattern on the cloth or other fabric under manufacture. I use crank
levers between the "lags" and pegs and the ends of the needles. The levers
are kept in position by "grids" or guides, one at each end of the cranked
levers.
My Invention consists, secondly, in the employment in jacquard looms of
an endless chain composed of pins carrying small pulleys arranged according
to the pattern to be produced. The chains may be adapted to any number
of harness or number to the round. The chain revolves on the cylinder
or band before described, which is mounted on a vibrating frame, and in
such manner as to rise and fall through the agency of a lever at each revolu-
tion of the loom. When I use the chain and pulleys the cylinder is made
with grooves the same pitch as the pulleys on the chain, and the grooves
guide the pulleys in their places when striking the levers.
Figure 1 of the accompanying Drawings is a side elevation and Figure 2
is a front view of so much of a jacquard as will be necessary to illustrate the
manner in which I carry my Invention into effect.
A is the vibrating frame, a detached view of which is given in plan at
Figure 3. This frame A has its fulcrum at B on the jacquard frame C; Dis
a cylinder mounted on a shaft E, free to revolve in bearings in the frame A,
as hereafter more clearly explained. The shaft E carries at one end a wheel
F in gear with another and similar wheel G on a shaft H, shown in dotted
lines in Figure 2. This shaft is surrounded by a long socket or guide I, and
within which it is free to revolve, carrying at its lower end a wheel J in gear
with another wheel K on a shaft L, carrying at its other end a star wheel M;
N is a lever free to rock on a stud E, and terminating at one end in a toothed
segment O in gear with the toothed wheel P, which communicates motion to a
pair of racks for raising and lowering the hooks to which the harness is attached,
as in jacquards of the ordinary construction for weaving woollen fabrics. The
vibrating frame A is jointed to the rocking lever N by a link Q, as shewn in
Figure 1, so that the vibrating. frame and rocking lever move together, the
former on its fulcrum B, and the latter on its stud E', and as will be presently
described. The cylinder D carries projections R, R, set at equal distances apart
on the periphery of the said cylinder, between which the "lags" S, S, enter as

page_text: the cylinder D revolves. These "lags" are made with apertures in them, as
seen in Figure 2, and pegs or pins T, T, are placed and arranged in these
apertures according to the pattern to be produced; V, V, are bell-crank levers
free to move about the pin W, and against which the pegs T, T, act in order to
cause the said bell-crank levers to strike off the hooks to which the harness is
attached; Y, Y, are "grids" or guides for keeping the bell-crank levers in
position. On motion being communicated to the machine the frame A is caused
to vibrate through the rocking lever N, which has itself motion communicated
to it through a lever or rod, not shewn, from the main shaft of the machine
and the cylinder D to rotate through the wheels F, G, J, K, and star wheel M,
and this latter receives motion through a train of wheels, not shewn, from the
main shaft of the loom. Now as this star wheel revolves, it at regulated
intervals stops the rotation of the cylinder D, and this takes place while the
lugs or pins on the wheel for communicating motion to it are not in one of
the notches in the wheel. During this rest or dwell the vibrating frame A
with the cylinder D rises, and the pegs which are inserted in the "lags" strike
those bell-crank levers which are opposed to them, as shown at 9, 9, 9,
Figure 2, and thus knock off the hooks to which the harness is attached.
In order that the wheels F and G shall not be thrown out of gear as the frame
A and cylinder D rise, I connect to the vibrating frame A a fork Z, which
takes into a groove Z, formed in the wheel G, and in such manner that as the
vibrating frame A moves the fork Z carries the wheel G with it and keeps it
constantly in gear with the wheel F. Sometimes instead of the cylinder
marked D in Figures 1, 2, and 3, I employ a cylinder made as shewn in
Figure 4, in which case instead of using "lags," also as before, I form an
endless chain composed of pins and small pulleys connected at equal distances
apart by links, and these links I prefer to stamp out of sheet iron. The pins
extend from end to end of the cylinder and between the flanges thereof; a, a,
are these flanges, having notches or cogs b, b, cut on their face and equally
divided one from the other in order to carry with them the endless chain of
pins and pulleys; c, c, are the grooves on the cylinder at equal distances
apart for guiding the pulleys in their place while striking the bell-crank
levers. The position of the pulleys is arranged according to the pattern to
be produced.
And having now described the nature of my said Invention and in what
manner the same is to be performed, I declare that I claim,-
First, the employment in jacquard looms of a vibrating frame in which a
cylinder carrying "lags" is free to revolve, an intermittent rotary motion
being communicated to the cylinder (through a star wheel), so that during the

page_text: rest or dwell thereby produced the cylinder and frame rise, and the pegs in
the "lags" through bell-crank levers strike off the hooks to which the harness
is connected, all substantially as herein-before described and illustrated in the
accompanying Drawings.
Second, the employment in the jacquard looms of a grooved cylinder for
guiding the pulleys while striking the bell-crank levers, substantially as herein-
before described and illustrated at Figure 4 of the accompanying Drawings.
In witness whereof, I, the said Abraham Haley, have hereunto set my
hand and seal, this Nineteenth day of November, One thousand eight
hundred and sixty-three.
