Year: 1859

page_text: LETTERS PATENT to James Bottomley, of North Bierley, near Bradford,
in the County of York, Manufacturer, and Alexander Hennah Martin,
of the same Place, Mechanic, for the Invention of "IMPROVEMENTS IN
MEANS OF APPARATUS EMPLOYED IN WEAVING."
Sealed the 25th January 1860), and dated the 16th September 1859.
PROVISIONAL SPECIFICATION left by the said James Bottomley and
Alexander Hennah Martin at the Office of the Commissioners of Patents;
with their Petition, on the 16th September 1859.
We,
JAMES BOTTOMLEY, of North Bierley, near Bradford, in the County of
York, Manufacturer, and ALEXANDER HENNAI MARTIN, of the same Place,
Mechanic, do hereby declare the nature of the said Invention for " IMPROVE.
MENTS IN MEANS OR APPARATUS EMPLOYED IN WEAVING," to be as follows:-
The object of the improvements is to give facility in the production of
various figured fabrics. When hooked rods are employed, the hooked ends of
which are capable of being acted upon by the knife edges of suitable levers or
sliding rods, whilst the other ends are connected to levers in connection with
the heddles, in order to produce various effects in the weaving, or with other
parts in the working of the loom; we form the needles, which are acted upon
by the jacquard or pattern surface, to select such rods, in order to their hooked
ends being placed in the position required, so that they may also act as stops
or holders to such rods; and we form such rods with catches, to be taken into
by the ends of such needles, by which facility is given for holding such reds

also control the motions of the levers or bars acting on the hooked rods, so
that in their motion to take on to the hooks they each incline to the same
point, whilst in going back they recede therefrom at an angle to each other,
by which facility is given in taking on to the hooks for operation, and of
clearing them after operation. We also incline the upper part of the knife
edge; and such inclination of the levers or bars is capable of adjustment. The
hooked-rods are drawn towards the needles by springs (by preference, coiled),
acting between such rods and the levers to which they are attached, and so as
to move with them, by which simplicity of working is obtained with little
friction. The jacquard cylinder is moved to and fro by a lever operated by a
cam course, formed in a cylindrical surface on the crank or other suitable
shaft. And in order to obtain repetitions of certain of the cards for the pro-
duction of plain weaving at certain parts when weaving by means of heddles,
the card cylinder is capable of being moved in either direction by a pair of
drivers or clawkers connected together, and they are thus brought into position
to be operated by a cord or band, or such like means acted upon by the
weaver, and worked by a separate tappet, whilst at other times the cylinder is
caused to rotate continuously by one of such clawkers or drivers.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Bottomley and Alexander Hennah Martin in the
Great Seal Patent Office on the 14th March 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
BOTTOMLEY, of North Bierley, near Bradford, in the County of York, Manu-
facturer, and ALEXANDER HENNAH MARTIN, of the same Place, Mechanic, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day. of September, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said James Bottomley and Alexander Hennah Martin, Her special
licence that we, the said James Bottomley and Alexander Hennah Martin,
our executors, administrators, and assigns, or such others as we, the said
James Bottomley and Alexander Hennah Martin, 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,

page_text: 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 MEANS OR APPARATUS EMPLOYED IN WEAVING,""."
upon the conditions (amongst others) that we, the said James Bottomley and
Alexander Hennah Martin, our executors or administrators, by an instrument
in writing under our or their hands and seals, or under the hand and seal..
of one of us or them, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was 'to bè
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 we, the said James Bottomley and Alexander
Hennah Martin, do hereby declare the nature of the 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, that is to
say:-
:
The object of the improvements is to give facility in the production of
various figured fabrics. When hooked rods are employed, the hooked ends of
whichare capable of being acted upon by the knife edges of suitable levers or
sliding rods, whilst their other ends are connected to levers in connection with
the heddles, in order to produce various effects in the weaving (or with other
parts in the working of the loom); we form the needles which are acted upon
by the jacquard or pattern surface to select such rods (in order to their hooked
ends being placed in the position required), so that they may also act as stops
or holders to such rods; and we form such rods with catches to be taken into
by the ends of such needles, by which facility is given for holding such rods
and parts acting therewith in position during changes of the other parts. We
also control the motions of the levers or bars acting on the hooked rods, so
that in their motion to take on to the hooks, they each incline to the same
point, whilst in going back they recede therefrom at an angle to each other,
by which facility is given in taking on to the hooks for operation, and of
clearing them after operation. We also incline the upper part of the knife
edge, and such inclination of the levers or bars is capable of adjustment. The
hooked rods are drawn towards the needles by springs (by preference, coiled),
acting between such rods and the levers to which they are attached, and so as
to move with them, by which simplicity of working is obtained with little
friction. The jacquard cylinder is moved to and fro by a lever operated by a
cam course formed in a cylindrical surface on the crank or other suitable
shaft. And in order to obtain repetitions of certain of the cards for the pra-

page_text: duction of plan weaving at certain parts when weaving. by means of heddles,
the card cylinder is capable of being moved in either direction by a pair of
drivers or clawkers connected together, and they are thus brought into position
to be operated by a cord or band, or such like means, acted upon by the
weaver and worked by a separate tappet, whilst at other times the cylinder
is caused to rotate continuously by one of such clawkers or drivers.
But that the nature of these improvements and the means.which we adopt
in carrying the same into effect may be fully understood, we will proceed to
duction of plan weaving at certain parts when weaving.by means of heddles,
the card cylinder is capable of being moved in eitlier direction by a pair of
drivers or clawkers connected together, and they are thus brought into position
to be operated by a cord or band, or such like means, acted upon by the
weaver and worked by a separate tappet, whilst at other times the cylinder
is caused to rotate continuously by one of such clawkers or drivers.
But that the nature of these improvements and the means.which we adopt
in carrying the same into effect may be fully understood, we will proceed.to
describe the Drawings annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows an end view, and Figure 2 a front view, of parts of a loom
with arrangements according to our improvements applied thereto; Figures 3,
4, 5, 6, 7, 8, 9, 10, 11, and 12, show some of the parts according to our
Invention separately. a, a, is the main framing of the loom ; b, the main or
crank axis; and c, the cam or tappet shaft, motions between which are
obtained in the ordinary manner; e, e, are the heddles, the upper part of each
of which is connected by the cords e¹, el, to the levers fand g. The levers f
are of the -form, and by means of the bands or wires f¹ are connected to the
arms g¹ of the levers g. To each of these levers g is connected one end of a
rod h, the other end of which at h¹ is hooked, so as to be capable of being
taken on to by the knife edge of a lever i or j, and these rods are guided in
their up-and-down motions by the grates h²; k are needles, each of which is
formed with a hooked end k¹, capable of taking on to the hooked part h³ of a
rod I, and of holding it there when so connected, whilst at other times the
outer end of this hooked part is capable of acting on the plane part of a rod h,
as shewn, to push it out of the way of the knife edge of a lever i, or into the
way of a lever j, as the case may be. The rods h are drawn towards the
instruments k by means of the springs 7. The levers i and j are kept to their
cams by the springs i, j, which are connected to the band or strap m passing
over the pulley m¹, and, they are operated by the cams or tappets n, n, on the
cam or tappet shaft c, and these levers i and j in their movements, as operated
by the cams or tappets n, n, incline towards and recede from each other, which
motions are obtained by their ends opposite from their axes," being controlled
by the guide: o, combined with their axes j¹ being also inclined, as shown.
The axes are supported in the adjustable bearings 3, by which facility is
given for obtaining the desired angles of motion to the axes j¹. The outer
end of the lever i moves in the guide o¹, whilst the outer end of the lever
moves in the guide o², and the amount of inclination of these levers in their

page_text: movement towards the same point is capable of adjustment. The parts of
hese levers i andj, where the knife edges i, j, for taking on to the hooks h¹
are formed, are inclined in relation to the other parts of those levers, as shewn,
bywhich greater certainty of operation thereto is obtained; p is the jacquard
cylinder acting on the needles, and it is supported by the lever p², which
turns upon the fixed axis p², and carries a truck or bowl p³, which takes into
the course formed in the cam 4 affixed on the main or crank axis b. The
instruments are capable of sliding freely in the spaces formed for them in
the fixed plates k, k³, and they are drawn backwards, so as to be in position
for their ends /4 being acted upon by the cards or pattern surface employed by
means of springs, one end of each of which is connected to a projection 7.6
from an instrument, whilst the other end is connected to a stationary rod T.
In order to obtain repetitions of any two of the cards, the operator passes a
ring at one end of the cord over the hook 7, by which the levers will be
borne towards the cam or tappet t, and the clawkers u and will be caused
alternately to act on the jacquard cylinder p carried by the lever p¹, and
thereby cause repetitions of two cards. When the cards are to go on in their
usual course, the ring 7 is released from the hook, thereby allowing the
levers to fall out of the way of the cam t, when the clawker u will be brought
into operation by the spring u¹.
Having thus described the means which we adopt in carrying out our
improvements, we would have it understood that we do not confine ourselves
to the precise details herein explained, as such may be varied without departing
from the peculiar character of the Invention; but what we do claim is, the
arrangement, adaptation, and combination of means for operating leaves of
heddles, substantially as herein explained.
In witness whereof, we, the said James Bottomley and Alexander
Hennah Martin, have hereunto set our hands and seals, this Thirteenth
day of March, in the year of our Lord One thousand eight hundred
and sixty.
