Year: 1870

page_text: LETTERS PATENT to James Robinson, of Bradford, in the County of
York, Manager, and John Peel, of Bradford, aforesaid, Overlooker,
for the Invention of "IMPROVEMENTS IN LOOKS FOR WEAVING."
Sealed the 23rd May 1871, and dated the 25th November 1870.
PROVISIONAL SPECIFICATION left by the said James Robinson and
John Peel at the Office of the Commissioners of Patents, with their
Petition, on the 25th November 1870.
Wé, JAMES ROBINSON, of Bradford, in the County of York, Manager,
and JOHN PEEL, of Bradford, aforesaid, Overlooker, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING,"
(to be as follows) :-
:-
This Invention relates to looms for weaving certain fancy fabrics, and
for improvements in which looms Letters Patent where granted to John
Carter Ramsden, dated the 14th day of January 1868, Number 125, and
the present improvements consist,-
Firstly. Instead of having the series of studs which carry the needles
at fixed places in the slidable bar, I have them fixed in brackets to fit

page_text: .
on the bar and capable of adjustment thereon to any desirable position
or at any distance apart according to the distance apart required for the
figures which are to be produced on the fabrics; also instead of having
tho series of short racks fixed on a slide bar which now work the needles,
I have a continuous rack bar so as to act upon the whole of the toothed 5
wheels of the said needles in the same manner in whatever position they
may be placed.
Secondly. In effecting the endways movement of the said slido bar
and the rack by means of a screw, on the end of which is mounted tho
noggin plate" or pin plate to be actuated by the hookers, this screw 1
being carried in a bracket readily fixed to the breast beam by a screw
bolt.
66
Thirdly. In constructing the loopers straight or nearly so and mounted
on a bar, which has in addition to the usual oscillatory motion a lateral
motion imparted to it by means of another lever actuated by a cam on 1
the low shaft which operates upon a rocking shaft on which are fingers
taking into or clipping upon the said looper bar and thereby produces
lateral motion, by means of which improvements the loopers are more
certain to scize the figure weft, and are more easily removed from the
fabric when weft is thrown in and without producing any derangement 2
of the figures produced thereon.
Fourthly. In the application of a locking apparatus to the rod,
marked k in the Specification referred to, used for stopping or giving
motion to the needles, which consists of a plate fixed on the top of the
said rod, having two recesses each formed at right angles to the other, 2
and a stop or slide block to fit into either of the said recesses, which is
operated by a spring so that when the rod is placed in one position the
stop holds it there, and when in the other position it also holds it in like
manner.
Fifthly. The Invention relates to means of working the healds or 8
heddles, and consists in the employment of two treading tappets and
levers to work two ordinary jack rods and half moons, to which cords
or chains are attached and connected to two leaves of healds respectively,
and these two are connected to other two leaves of healds by cords and
pulleys, so that by the action of two treading tappets the four leaves of 3
the healds are operated in one direction, and springs are employed to
produce the reaction thereof, or to operate the said heald's in the opposite
direction.

page_text: In the working of this part of our Invention we employ healds without
eyes or mails, but which are looped in suitable manner so that when two
leaves connected together are placed in a certain relative position a loop
is formed of the two healds of such extent that the warp threads passing
through the two licalds can be lifted or lowered by harness operated by
jacquard apparatus, and when the two leaves are operated or placed in
another position relatively to each other, the loop is closed upon the warp
thread and thus forms an eye or mail whereby the operating of the two
leaves of healds together will lift or lower the said warp as required.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Robinson and John Peel in the Great Scal
Patent Office on the 25th May 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
ROBINSON,, of Bradford, in the County of York, Manager, and JOHN
PEEL, of Bradford, aforesaid, Overlooker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of November, in the
year of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, givo
and grant unto us, the said James Robinson and John Peel, Her special
licence that we, the said James Robinson and John Pecl, our executors,
administrators, and assigns, or such others as we, the said James
Robinson and John Peel, our 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 King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVEMENTS IN LOOKS FOR WEAVING," upon the
condition (amongst others) that we, tho said James Robinson and John
Peel, our executors or administrators, by an instrument in writing under
our, or their, or one of our or 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 Scal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that we, the said James Robinson and John Peel,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement and accompanying Sheets of Drawings
(that is to say):-
This Invention relates to looms for weaving certain fancy fabrics, and
for improvements in which looms Letters Patent were granted to John
Carter Ramsden, dated the 14th day of January 1868, No. 125, and the
present improvements consist,-
G
Firstly. Instead of having the series of studs which carry the needles 1
at fixed places in the slideable bar, we have them fixed in brackets to fit
on the bar and capable of adjustment thereon to any desirable position
or at any distance apart according to the distance apart required for the
figures which are to be produced on the fabrics; also instead of having
the series of racks fixed on a slide bar which now work the needles we 1
have a continuous rack bar so as to act upon the whole of the toothed
wheels of the said needles in the same manner in whatever position they
may be placed.
Secondly. In effecting the endways movement of said slide bar and
the rack by means of a screw, on the end of which is mounted the 2
"noggin plate" or pin plate to be actuated by the hookers, this screw
being carried in a bracket readily fixed to the breast beam or end frame
by a sorew bolt.

Thirdly. In constructing the loopers straight or nearly so and mounted
on a bar which has in addition to the usual oscillatory motion a lateral 25
motion imparted to it by means of another lever actuated by a cam on
the low shaft which operates upon a rocking shaft on which are fingers.
taking into or clipping upon the said looper bar and thereby produces
lateral motion, by means of which improvements the loopers are more
certain to seize the figure weft and are more easily removed from the 30
fabric when weft is thrown in and without producing any derangement of
the figures produced thereon.
..
In order that this Invention may be clearly understood we herein refer
to two accompanying Sheets of Drawings (of such parts as are necessary
to shew our improvements) of a loom similar in its general constructión 35
to the loom illustrated in the Specification of John Carter Ramsden's
Patent herein-before referred to.

page_text: DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an end elevation; Fig. 2 is a cross section; Fig. 3 is a front
elevation; and Fig. 4 is a plan (of a portion thereof), with our improve-
ments applied thereto. The first part is referred to by the following
letters :-
C
A is the slide or slideable bar, which is supported in brackets B fixed
to the breast beam B', and the series of studs or axes of the toothed
wheels C which carry the needles O³ are mounted on brackets D fitted
to and capable of being moved into position on the slide bar A, and
) secured by means of set screws a in any desirable position or at any
suitable distance apart according to the required disposition of the figures
to be produced on the fabric; E is the rack bar which gives motion to
the wheels or needle carriers O for working the said needles. The teeth on
this rack bar are made continuous, that is, without intermitting spaces,
as in the Specification of John Carter Ramsden's Patent, so that the
wheels O will gear into it at any part or position in which they may
be set or placed.
The several parts above referred to are shewn in detail full size at
Figs. 5 and 6.
To effect the required action of the needles we employ similar means
to those shewn and described in the Specification of John Carter
Ramsden's Patent, but in order to avoid any slip or misaction we apply
a locking apparatus F to the top of the shaft K, which apparatus is
shewn full size at Fig. 7.
The second part is refered to by the following letters, where G is the
screw which is supported at one end by a bracket H bolted to the loom
end opposite the breast pin, and I is the "noggin plate" or pin plate
fixed on the end of the said screw. This plate is turned right or left
as required by the hookers J and J attached to the levers L and M, to
) which are also attached hooks N and O, which are placed in or out of
position by cords from the jacquard engine, so that either may bo
operated by a lever P which is worked by a cam Q on the crank shaft.
This screw passes through a tapped lug or arm R, which is fixed on the
slide bar, consequently by the turning of the screw right or left so will
5 the bar be moved in one or the other direction, and as a guide or test to
the attendant of the correct movements or otherwise of the slide bar we
fix to the said arm a pointer S and form an index or division marks on

page_text: the bracket so that should there be any incorrect action of the said slide
bar the attendant can readily detect it and set the loom in proper working
order again.
The third part of this Invention is refered to by the following.
letters:-T (Fig. 2), aro the loopers, which instead of being hooked or
cranked, as shown in the Drawings of the Specification of Patent granted
to John Carter Ramsden, are nearly straight, so that they lie nearly
parallel with the warp threads when brought into use, and are thereby
more certain to scize the figure weft when passed into the shed. The
bar T on which the loopers are mounted has the usual oscillatory or
rocking motion given to it by means of the vertical slide rod U, in the
top end of which is a long slot taking on a lever T³ fixed on the said.
bar, and to the said slide rod is attached a lever U, which is actuated
in one direction by a double cam U³ fixed on the low shaft of the
loom, and in the other direction by a spring U³. This looper bar has
also a lateral or sideways motion imparted to it by means of a lever V.
(actuated by a cam V' fixed on the low shaft) connected by a rod V³ to,
a lever V³ fixed on a rocking shaft V* on which are fixed two fingers or
arms which clip slide bearings V³ which carry the said looper bar, and
a spring V⚫ produces reaction, thus the looper bar has a compound
motion given to it, a rocking and a lateral slide by which we find that
the loopers are more easily removed from the fabric, and consequently
without producing any derangement of the figures..
In witness whereof, I, the said John Peel, for and on behalf of
myself and the said James Robinson, have hereunto set my hand
and seal, this Twenty-fourth day of May, in the year of our Lord
One thousand eight hundred and seventy-one.
