PROVISIONAL SPECIFICATION.
Improvements in Brussels-carpets and similar Fabrics, and in
Looms for Weaving the same.
I, WILLIAM YOUNGJOHNS, of Blackbrook, Kidderminster, in the County of
Worcester, Power Loom Tuner, do hereby declare the nature of this invention to
be as follows:-
My invention relates to Brussels-carpets and similar fabrics, and to looms for
weaving the same.
In the Specification of former Letters Patent dated 29th March 1879, No. 1252,
there is described a peculiar method of weaving carpets with an "independent" or
additional thick back, which forms a soft cushion to the surface of the carpet, and
gives the carpet additional strength and consequent durability, and which, when
worn or cut, will not necessarily release the surface or front of the carpet.
The object of my present invention is to adapt the loom described in the said
former Specification, for weaving with such an "independent" or additional thick
back, Brussels-carpets and similar fabrics in the manufacture of which yarns of
different colours are raised into loops as required to produce the pattern.
For this purpose, I provide, as hereinafter mentioned, for the successful and
advantageous use of Jacquard apparatus in combination with mechanism such as
that described in the said former Specification, for weaving carpet with the said
"independent" or additional thick back.
In the said former Specification, Brussels-carpet is mentioned as one of the
fabrics which can be woven on the improved loom therein described; and it is true
that Brussels-carpet with a limited amount of ornamentation (such as longitudinal
stripes of different colors) can be produced by following the directions given in the
said Specification. But, in order to weave upon such a loom, a Brussels-carpet with a
pattern, it is necessary that the further additions and improvements herein
mentioned should be embodied in the said loom.
In carrying my present invention into practice, I proceed as follows, that is to
say: I make the frame of the loom with vertical extensions upon which are
supported Jacquard apparatus and mechanism connected therewith substantially as
in an ordinary Brussels-carpet loom. I also provide the loom with other parts
ordinarily employed in Brussels-carpet looms, such as the frames for carrying the
bobbins, the guard or frame for guiding the worsted or yarn, and the top or jack
levers. The brake usually employed in Brussels-carpet looms, for arresting or
retarding the motion of the fine chain, is or may be dispensed with in my
improved loom.
"
In order to obtain sufficient space immediately bebind the lay or lathe for what is
known as the "harness or "gear," so as to permit the use of weights of nearly the
same size and shape as those ordinarily employed in Brussels-carpet looms, I remove
the mechanism for operating the sliding picker-shafts, as described in the said former
Specification, from the cross-bar near the front of the loom to the cross-bar near
the back of the loom. This mechanism comprises a toothed wheel having upon each
side of it a suitable cam. These cams actuate levers which are fixed on two shafts
in axial line with each other for the purpose of operating the picker-shafts. The
removal of the said mechanism from the front to the back of the loom alters
the relative positions of the parts; to adapt the mechanism, therefore, for operating
under these changed conditions, I alter the shape of the said cams in such a manner
that they will impart the proper movement to the sliding picker-shafts. For this
purpose, moreover, I connect the two levers at the sides of the loom, with
the sliding picker-shafts by means of suitable rods or links. For operating the

page_text: "lifting-board," that is to say, the board for raising and lowering the worsted
threads which are to form the surface of the fabric, I provide a cam or tappet such
as that usually employed in Brussels-carpet looms, but of such shape that it will
hold up the lifting-board while two picks or shots are made across the back of or
below the worsted, and will hold down the said lifting-board while one pick or shot
is made across the front of the worsted or above the same. For operating the
"lash," that is to say; the board for raising and lowering the threads selected
by the jacquard, I provide a cam or tappet such as that usually employed in
Brussels-carpet looms, but of such shape that it will hold the lash up while
two picks or shots are made across the back of or below the worsted, and will hold
the said lash down while one pick or shot is made across the front of the worsted
or above the same.

COMPLETE SPECIFICATION.
Improvements in Brussels-carpets and similar Fabrics, and in
Looms for Weaving the same.
I, WILLIAM YOUNG JOHNS, of Blackbrook, Kidderminster, in the County of
Worcester, Power Loom Tuner, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to Brussels-carpets and similar fabrics, and to looms for
weaving the same.
21
In the Specification of former Letters Patent dated 29th March 1879, No. 1252,
there is described a peculiar method of weaving carpets with an "independent
or additional thick back, which forms a soft cushion to the surface of the carpet,
and gives the carpet additional strength and consequent durability, and which,
when worn or cut, will not necessarily release the surface or front of the carpet.
The object of my present invention is to adapt the loom described in the said
former Specification, for weaving with such an independent" or additional thick
back, Brussels-carpets and similar fabrics in the manufacture of which yarns of
different colours selected by a Jacquard apparatus are raised into loops as required
to produce the pattern, such loops being either cut or left uncut according to the
kind of carpet being manufactured.
<<
For this purpose, I provide, as hereinafter mentioned, for the successful and
advantageous use of Jacquard apparatus in combination with mechanism, such as
that described in the said former Specification, for weaving carpets with the said
"independent" or additional thick back.
In the said former Specification, Brussels-carpet is mentioned as one of the
fabrics which can be woven on the improved loom therein described; and it is true
that Brussels-carpet with a limited amount of ornamentation (such as longitudinal
stripes of different colours) in the production of which it is not necessary to use a
jacquard, can be produced by following the directions given in the said Specifica-
tion. But, in order to weave upon such a loom a Brussels-carpet with a pattern,
it is necessary that the further additions and improvements herein mentioned should
be embodied in the said loom.
In the accompanying drawings.
Figure 1 is a plan, partly in horizontal section, showing a portion of a Brussels-
carpet loom constructed according to my present improvements.
Figure 2 is a front elevation of the same, partly in vertical section.
Figure 3 is a section on the line x, x, Figure 1, looking towards the right hand
side of the loom.

page_text: Figure 4 is a section on the line x, x¹, Figure 1, looking towards the left hand
side of the loom, and
Figure 5 is a side elevation showing the cam hereinafter referred to for operating
the "lash."
Like letters indicate corresponding parts throughout the drawings.
:-
In carrying my present invention into practice, I proceed as follows, that is to
say I construct a loom substantially in the manner described in the said former
Specification, but with the alterations and additions hereinafter described, viz. :-
I make the frame of the loom with vertical extensions upon which are supported
Jacquard apparatus and mechanism connected therewith substantially as in an
ordinary Brussels-carpet loom. I also provide the loom with other parts ordinarily
employed in Brussels-carpet looms, such as, the frames for carrying the bobbins,
the guard or frame for guiding the worsted or yarn, and the top or jack levers.
The brake usually employed in Brussels-carpet looms for arresting or retarding.
the motion of the fine chain, is or may be dispensed with in my improved loom.

or
In order to obtain sufficient space immediately behind the lay or lathe for what
is known as the "harness" or "gear," so as to permit the use of weights of nearly
the same size and shape as those ordinarily employed in Brussels-carpet looms, I
remove the mechanism for operating the sliding picker-shafts, as described in the
said former Specification, from the cross-bar near the front of the loom to the
cross-bar near the back of the loom, that is to say, instead of attaching the supports
for the said mechanism to the front cross-bar a as heretofore, attach the said
supports to the rear cross-bar a' so that the said mechanism occupies the position.
shown in the drawings, leaving room in front of it for the ordinary "harness"
gear." The said mechanism comprises a toothed wheel b having upon its sides
suitable cams c, c, which actuate levers d, d' fixed on two shafts e, el in axial line
with each other, for the purpose of moving the picker-shafts f¹, into and out of
the path of the tappets for operating them. The removal of the said mechanism
from the front to the back of the loom, alters the relative positions of the parts..
To adapt the mechanism, therefore, for operating under these changed conditions,
I alter the shape of the said cams c, c', that is to say, I make these cams of the
shape shown in Figures 3 and 4, so that they will impart the proper movement to
the sliding picker-shafts. Moreover I connect the two levers g, g' fixed on the
shafts e, e at the sides of the loom, with the sliding picker-shafts f, f' by means of
rods or links h, h¹.
For operating the "lifting-board," that is to say, the board for raising or
lowering the worsted threads which are to form the surface of the fabric, I provide
cams or tappets j, j₁ such as are usually employed in Brussels-carpet looms, but
of the shape shown in Figures 3 and 4, so that they will hold up the lifting-board
while two picks or shots are made across the back of or below the worsted, and
will hold down the said lifting-board or allow the same to remain down while one
pick or shot is made across the front of the worsted or above the same.
For operating the "lash," that is to say, the device for raising and lowering the
threads selected by the jacquard, I provide a cam or tappet k such as that usually
employed in Brussels-carpet looms, but of the shape shown in Figure 5, so that it
will hold the lash up while two picks or shots are made across the back of or below
the worsted, and will hold the said lash down while one pick or shot is made across
the front of the worsted or above the same.
By constructing a loom in the manner hereinbefore described, I adapt the same
for weaving Brussels-carpet and other fabrics in which the pattern is produced by
the aid of a Jacquard apparatus.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
First. A loom in which mechanism for weaving carpets with an independent or
additional thick back as described in the said former Specification No. 1252 of

page_text: 1879, is combined with a Jacquard apparatus in the manner herein before described
or by the use of equivalent mechanism, for the purpose specified.
Second. A Brussels-carpet or similar fabric manufactured with an independent
or additional thick back, by means of a loom such as is described in the first
claiming clause.
