IMPROVEMENTS IN LOOMS FOR WEAVING CHENILLE OR Fur PILE FABRICS
Year: 1882

page_text: LETTERS PATENT to William Adam of the firm of Tomkinson and Adam
of Kidderminster in the County of Worcester Carpet Manufacturer for an
Invention of IMPROVEMENTS IN LOOMS FOR WEAVING CHENILLE OR Fur
PILE FABRICS
PROVISIONAL SPECIFICATION left by the said William Adam at the Office
of the Commissioners of Patents on the 11th December 1882.
WILLIAM ADAM of the firm of Tomkinson and Adam of Kidderminster in the
County of Worcester Carpet Manufacturer "IMPROVEMENTS IN LOOMS FOR
WEAVING CHENILLE OR FUR PILE FABRICS
"
The Invention has for its object improvements on an invention for which
Letters Patent were granted to me dated November 22. 1880 No. 4842 and relates
to the application thereto of means for mechanically combing or brushing up the
chenille or fur in its proper position as it is being woven into the fabric.
Previous to my said former invention when weaving chenille or fur pile fabrics
is was usual after the chenille or fur had been laid in position between the ground
warps and the "catcher warp" for the attendant to comb the chenille or fur by
a hand comb into its required position, this however was found troublesome
in use and caused considerable loss of time in the weaving of the fabric as it
was necessary for the loom to be at rest to enable such combing up of the chenille
or fur to be effected.
According to my said former invention in order to obviate the necessity for
such combing up of the chenille or fur I caused a rising motion to be given
to the reed, and although this is found sufficient for some classes of work it is
thought desirable in other classes of work to have a supplementary combing or
brushing action.
Now according to my present Invention I mount above the fabric and just at
the back of the breast beam a bar provided with downwardly projecting teeth or
with a brush.
This brush or comb bar is carried by suitable arms which are connected to levers
operated by cams, one of such levers being operated so as to move the brush or

page_text: comb bar backwards beyond the fell of the fabric, the other lever being operated
so as to cause the said brush or comb bar to descend slightly and thereby cause the
teeth or brush thereof to enter amongst the "catcher" warps, springs being preferably
employed to operate such levers in the reverse directions.
By these means when the lathe recedes from the fell of the fabric the brush
or comb bar is caused to follow it (sooner or later) a certain distance and then to
descend after which the said brush or comb bar is caused to return towards the
breast beam and in its course it first brushes or combs the chenille or fur up
into its proper position and then rises above the completed fabric to its forward
position, where it is out of the way and does not interfere with the weaver's
attendance to the loom.
The required movements to this comb or brush bar may however be imparted
thereto by other arrangements of mechanism without departing from my
invention.

by the said William Adam in the Great Seal Patent Office on the 5th June
1883.
WILLIAM ADAM of the firm of Tomkinson and Adam of Kidderminster in
the County of Worcester Carpet Manufacturer "IMPROVEMENTS IN LOOMS FOR
WEAVING CHENILLE OR FUR PILE FABRICS"
The Invention has for its object improvements on an invention for which
Letters Patent were granted to me dated November 22nd 1880 No 4842 and relates
to the application thereto of means for mechanically combing or brushing up the
chenille or fur into its proper position as it is being woven into the fabric.
Previous to my said former Invention when weaving chenille or fur pile fabrics
it was usual after the chenille or fur had been laid in position between the ground
warps and the "catcher warp" for the attendant to comb the chenille or fur by
a hand comb into its required position, this however was found troublesome in
use and caused considerable loss of time in the weaving of the fabric as it was
necessary for the loom to be at rest to enable such combing up of the chenille or
fur to be effected.
According to my said former invention in order to obviate the necessity for
such combing up of the chenille or fur I caused a rising motion to be given
to the reed, and although this is found sufficient, for some classes of work it is
thought desirable in other classes of work to have a supplemental combing or
brushing action.
Now according to my present Invention I mount above the fabric and just at
the back of the breast beam in its position of rest a bar provided with downwardly
projecting teeth or with a brush.
This brush or comb bar is carried by suitable levers or arms which are connected
to bars or levers operated by cams, one of such bars or levers being operated so as
to move the brush or comb bar backwards beyond the fell of the fabric, the
other lever being operated so as to cause the said brush or comb bar to descend
slightly and thereby cause the teeth or brush thereof to enter amongst the
"catcher" warps, springs being preferably employed to operate such levers in the
reverse directions.
By these means when the lathe recedes from the fell of the fabric the brush
or comb bar is caused to follow it (sooner or later) a certain distance and then
to descend after which the said brush or comb bar is caused to return towards
the breast beam and in its course it first brushes or combs the chenille or fur
up into its proper position and then rises above the completed fabric to its forward
position.
And in order that my said Invention may be more clearly understood and
readily carried into effect I will proceed aided by the accompanying Drawings
•
Figure 1 is an end view partly in section and Figure 2 is a front elevation or
parts of a loom for weaving chenille or fur pile fabrics showing my present
Invention applied thereto.
a is the main framing b is the first motion shaft c is the cam or tappet shaft
d is the lathe and e are the healds all of which and the parts for inserting the
chenille or fur and ground wefts and the methods of operating the same are

page_text: arranged as heretofore but according to my present Invention in order to comb or
brush up the chenille or fur into its proper position I employ a comb or brush
bar mounted (in its position of rest) above the fabric and just at the back of the
breast beam a and such comb or brush bar f is provided with downwardly
projecting teeth or with a brush,
This brush or comb bar f is carried by suitable levers or arms f¹ which are
connected to bars or levers ƒ ƒ³ operated respectively by cams g h the bar or
lever f being operated so as to move the brush or comb bar f backwards beyond
the fell of the fabric, and the bar or lever f³ being operated so as to cause the said
brush or comb barf to descend slightly in such last mentioned position and
thereby cause the teeth or brush thereof to enter amongst the catcher warps i
springs being preferably employed to operate such levers f2 f³ in the reverse
directions.
By these means when the lathe d recedes from the fell of the fabric the brush
or comb bar f is caused to follow it (sooner or latter) a certain distance and then
to descend after which the said brush or comb bar is caused to return towards
the breast beam a¹ and in its course it rises and brushes or combs the chenille
or fur up into its proper position and then goes above the completed fabric to its
forward position where it is out of the way and does not interfere with the
weaver's attendance on the loom.
If desired instead of employing a bar or lever f2f3 at each side of the loom only
one of each such bars or levers may be employed placed in the centre of the loom
in which case the levers or arms f¹ are connected together by a cross bar provided
with a descending bar connected to each of such bars or levers f2 fs..
The required movements to this comb or brush bar f may be imparted thereto
by other arrangements of mechanism without departing from the peculiar character
of my Invention.
Having thus described the nature of my said Invention and the mode in
which I carry the same into effect I would have it understood that what I
claim is
First. The combination with a loom for weaving chenille or fur pile fabrics of
an automatic brush or comb bar f moving in the directions substantially as herein
shown and described and for the purpose stated and
Second. The combination with a loom for weaving chenille or fur pile fabrics
of a brush or comb bar f levers or arms f¹, bars or levers f2 f³ and cams'g and h
substantially as herein shown and described and for the purpose stated.
£. In Witness whereof I the said William Adam have hereunto set my hand
and seal this first day of June, in the year of Our Lord one thousand
eight hundred and eighty three.
