Year: 1858

page_text: LETTERS PATENT to Joseph Wade, of Bradford, in the County of York,
Manufacturer, for the Invention of "IMPROVEMENTS IN MEANS OR APPARATUS
EMPLOYED IN WEAVING.".
Sealed the 11th March 1859, and dated the 14th December 1858.
PROVISIONAL SPECIFICATION left by the said Joseph Wade at the
Office of the Commissioners of Patents, with bis Petition, on the 14th
December 1858.
I, JOSEPH WADE, of Bradford, in the County of York, Manufacturer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN MEANS
OB APPARATUS EMPLOYED IN WEAVING," to be as follows:-
The improvements have for their object the obtaining facility in changing
from plain weaving to tweel or such like weaving, and then to plain again
when desired, and so on. For this purpose, in place of employing only a pair
of treddle levers or such like instruments operated by a pair of tappets to give
motion to the heddles, there are four or other number of treddle levers con-
nected to the heddles according to the extent of change which it may be
desired to produce with a separate tappet or like acting surface to each
treddle lever adapted to produce the variation or variations desired in the
shedding. And these treddle levers or such like acting instruments are
capable of being connected together so as to form one pair as when weaving
plain, and then ordinary plain weaving will be produced.
Catches or such like connecting means operate to connect the two or other

page_text: number of levers together, and these connecting means are operated at the
times desired by jacquard or other pattern surface.
One arrangement of pattern surface for acting upon the connecting means
consists of an endless chain of studs or surfaces capable of acting on a lever or
levers for the purpose of placing such lever or levers in the way of holding
other levers which by cords or bands are connected to the catches; springs or
weights aid the motion of the catches, but this may be varied.
The beddles are connected at their undersides to cords passing under pulleys,
which are connected to a frame or frames acted upon by spring pressure, so as
to impart uniformity of tension thereto.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Wade in the Great Seal Patent Office on the 14th
June 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
WADE, of Bradford, in the County of York, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of December, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Joseph Wade, Her special licence that I, the said
Joseph Wade, my executors, administrators, and assigns, or such others
ás I, the said Joseph Wade, 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 MEANS OR APPARATUS EMPLOYED IN WEAVING," upon the
condition (amongst others) that I, the said Joseph Wade, my executors 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 Joseph Wade, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following.
statement thereof, that is to say :-
.
The improvements have for their object the obtaining facility in changing
from plain weaving to tweel or such like weaving, and then to plain again
when desired, and so on. For this purpose, in place of employing only a pair
of treddle levers or such like instruments operated by a pair of tappets to give
motion to the heddles, there are four or other number of treddle levers con-
nected to the heddles according to the extent of change which it may be
desired to produce, with a separate tappet or like acting surface to each treddle
lever adapted to produce the variation or variations desired in the shedding.
And these treddle levers or such like acting instruments are capable of being
connected together so as to form one pair as when weaving plain, and then
ordinary plain weaving will be produced.
Catches or such like connecting means operate to connect the two or other
number of levers together, and these connecting means are operated at the
times desired by jacquard or other pattern surface.
One arrangement of pattern surface for acting upon the connecting means
consists of an endless chain of studs or surfaces capable of acting on a lever or.
levers for the purpose of placing such lever or levers in the way of holding
other levers which by cords or bands are connected to the catches; springs or
weights aid the motion of the catches, but this may be varied.
The heddles are connected at their undersides to cords passing under pulleys,
which are connected to a frame or frames acted upon by spring pressure so as
to impart uniformity of tension thereto.
But that the nature of my said Invention, and the means which I adopt in
carrying the same into effect may be fully understood, I will proceed more fully
to describe the same, aided by the accompanying Drawings.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows part of the front view, and Figure 2 an end view of a loom..
with my improvements applied thereto. The other Figures show parts sepa-
rately, in order to their being more clearly understood:
a, a, is the main framing of the loom, 6 the main or crank axis, and c the
cam or tappet shaft receiving motion from the crank axis by tooth gear, as
shown, and as is well understood; d, d¹ and e; e¹, are two pairs of treddle
levers arranged according to my Invention, and turning upon an axis. f, whilst
they carry trucks or bowls g, and are capable of being acted upon by the
tappets h, h. The levers d, d', and e, e', are capable of being separately acted
upon by tappets h, h, or the levers d, d', are capable of being connected

page_text: e,
el
may
be
together so as to act as one lever, and in like manner the levers
connected together to act as one lever. The connections are obtained in the
arrangement shown by the catches or bolts i, which are formed to slide, one
in bearings carried by the lever d, the other in bearings carried by the lever 6,
and they are forced outwards by springs j, so that the outer ends of that catch
or bolt i carried by the lever d may pass into the projection d, carried by the
lever d¹, so as to connect those levers together, whilst the other catch or bolt i
passes into a projection 6 from the lever e¹. The other end of each of the bolts
or catches i is formed with a pin i, capable of being acted upon by the upper and
forked end of a lever k, turning upon the stud k, and at its other end it is con-
nected by the cord or band or rod 7 to an L lever m, turning on an axis of
motion m¹, and at its other end connected by the link m² to one end of a lever
m³, which is acted upon by the jacquard or pattern surface passing over a,
suitable cylinder n, and when the lever m³ is lifted, it will act upon the lever k
to pull back the bolts i, when the levers d, d,and e, e¹ will be separated so as
to be acted upon by their tappets separately. And the lever m³, when raised.
by the jacquard or pattern surface, is supported in that position by the pro-
jection m resting upon the surface p¹ of the lever p, until the levers d, d',,
and e, e, are again required to be connected together, when the studs or pro-
jections n on the jacquard or pattern surface will act upon the end p² of the
lever p to release it from the projection m on the lever m³, by which the
springs will be free to act upon the bolts i, and thereby connect the levers d
and d¹, e and e¹. The levers d, d', e and e¹ are each connected by rods 0, 0, 0, to
the levers supporting leaves of heddles q in the ordinary manner.
I would state, that although I have only shown in each case two levers
capable of acting together as one, other numbers of them may be connected
together by catches or such like connecting means, there being tappets for
each; but when other numbers of levers are thus arranged, motion will be
varied to the tappets operating them to effect the sheddings at the times
desired, as is, well understood. The pattern surface to act on the lever m³ may
be formed of studs, or otherwise, as desired.
The heddles are at their undersides connected to the cords, q', passing under
the pulleys r carried by the ends of bands r¹, which pass round pulleys con-
nected to the frames, which is acted upon by springs, s¹, so as to preserve
uniformity of tension, to the heddles.
Having thus described the nature of my said Invention, and the means
which I adopt in carrying the same into effect, I would have it understood
that I do not confine myself to the precise details shown and described, as
these may be varied without departing from the peculiar character of my

page_text: Invention; but what I do claim is, the so arranging treddle levers for acting
upon beddles as employed in weaving, that two or more of them may, when
desired in the working of the loom, be connected together, and then act as one
lever to cause all the heddles with which they are connected to be operated
upon simultaneously, and then such levers may be released to act indepen-
dently on their respective heddles to obtain facility in changing the character
of the weaving, substantially as explained.
In witness whereof, I, the said Joseph Wade, have hereunto set my
hand and seal, this Eleventh day of June, in the year of our Lord
One thousand eight hundred and fifty-nine.
Witness,
JOSEPH AKEROYD,
Bradford.
