PROVISIONAL SPECIFICATION left by the said John Dodd and William
Adam at the Office of the Commissioners of Patents on the 30th June 1882.
JOHN DODD of Oldham in the County of Lancaster, Machinist and 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."
Our invention has for its object improvements on an invention for which
Letters Patent were granted to William Adam dated November 22, 1880 No. 4842
and relates, Firstly to a novel arrangement of parts for giving the requisite motions
and dwells to the lathe, cambs or healds and picking motions.
For this purpose we arrange the parts so that when required the combs or healds
and the latbe are operated, the picking motion is brought into play and the
requisite motion is given to the shuttle whilst the picking apparatus, the cambs or
healds and the lathe are kept out of action at the times when motion is given to
the chenille o fur inserting appliances.
In carrying this part of our invention into effect, we fix the picking cams or
strikers on the first motion shaft and we connect this shaft by gearing properly
timed to another shaft which carries the cams or tappets for giving motion to the
cambs or heads and to the lathe and the cam which brings the tongues or fingers
of the picking apparatus at the proper times into position to be acted upon by the
picking cams or strikers whilst at other times the said tongues or fingers are allowed
to fall out of such position.
The lathe is operated by toggle links or levers connected by a link to the main
levers which are acted upon by cams on the cam or tappet shaft and these cams
have formed thereon the necessary number of rises and falls to give the required
number of motions to the lathe for each insertion of the chenille or fur,

page_text: According to the second part of our invention we impart extra falling and rising
motions to the reed for each insertion of the chenille or fur in order the better to
ensure the chenille or fur pile being brought up into its proper position.
According to the third part of our invention we employ a fixed reed placed as
close as possible to the track of the catch warp needles in order to ensure the said
needles entering their proper spaces between the warp threads.
According to the fourth part of our invention, we impart extra falling motions
and dwells to the catch warp needles in order to facilitate the setting and holding
of the fur or chenille as it is being brought into its proper position.
According to the fifth part of our Invention when it is required to insert an
extra or a floating warp, we employ an extra shaft or leaf of cambs or healds which
we operate by the other leaves or shafts or by some of them arcording as it is
required to raise such extra shaft or leaf at the rise of every camb or heald or at the
rise of only certain of them. This we effect by mounting in sockets or guides at
the top of such extra shaft or leaf, one or more projections capable of being fixed in
position by screw or otherwise so as to extend over some or all of the other shafts
or leaves and thereby cause such extra leaf or shaft to be raised at the rise of
shaft or leaf or at the rise of only some of them.

JOHN DODD of Oldham in the County of Lancaster. Machinist and 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 FÀBRICS.”
Our Invention has for its object Improvements on an Invention for which Letters
Patent were granted to William Adam' dated November Twenty second, One
thousand eight. hundred and eighty No. 4842 and relates firstly to a novel
arrangement of parts for giving the requisite motions and dwells to the lathe,
healds and picking motions.
'
.
.
For this purpose we arrange the parts so that when required the healds and the
lathe are operated, the picking motion is brought into play and the requisite
motion is thereby given to the shuttle whilst the picking apparatus, the healds and
the lathe are kept out of action at the times when motion is given to the Chenille
or fur inserting appliances.
In carrying this part of our Invention into effect we fix the picking cams or
strikers on the first motion shaft and we connect this shaft by gearing properly
timed to another shaft which carries the cams, or tappets for giving motion to the
healds and to the lathe and the cam which brings the tongues or fingers of the
picking apparatus at the proper times into position to be acted upon by the picking
cams or strikers whilst at other times the said tongues or fingers are kept out of
such position.
The lathe is operated by toggle links or levers connected by a link to the main
levers which are acted upon by cams on the cam or tappet shaft and these cams
have formed thereon the necessary number of rises and falls to give the required
nuniber of motions to the lathe for each insertion of the Chenille or fur.
According to the second part of our Invention we impart extra falling and rising
motions to the reed for each insertion of the Chenille or fur in order the better to
ensure the Chenille or fur pile being brought up into its proper position.
According to tlie third part of our Invention we employ a fixed reed placed as
close ús possible to the track of the catcher warp needles in order to ensure the
suid needles entering their proper spaces between the warp threads.
According to the fourth part of our Invention we impart extra fulling motion's
aud dwells to the catcher warp needles in order to facilitate the setting and holding
of the fur or Chenille as it is being brought into its proper position.
According to the fifth part of our Invention when it is required to insert an
extra or a floating warp we employ an extra shaft or leaf of healds which we
operate by the other leaves or shafts or by some of them according as it is
required to raise such extra shaft or leaf at the rise of every heal or at the rise
of only certain of them. This we effect by mounting in sockets or guides at the
top of such extra shaft or leaf one or more projections capable of being fixed in
"position by screw or otherwise so as to extend over some or all of the other shafts
ur leaves and thereby cause such extra leaf or shaft to be raised at the rise of every
shaft or leaf or at the rise of only some of them.
And in order that our said Invention may be more clearly understood and readily
arried into effect we will proceed aided by the accompanying, Drawings more,
fully to describe the same.

loom, but in order to prevent confusion we have not shewn all the improvements
combined in the same Figures.
is the first motion shaft and c is the shaft which carries
a is the main framing
the cams d, e, f, g, h, and i.
The cams d give motion to the heddles d' through the intervention of the levers d
connecting rods d³ and levers d'.
The cams e act upon the short ends of the levers to cause their longer ends to
hold the picking tongues or fingers which are pivotted to the inclined shaft k
out of position to be acted upon by the picking cams or strikers k at the times when
the picking apparatus is at rest but permits the short ends of the said levers j to fall
into the notches or recesses c¹ when the picking apparatus is required to act at
which time the longer ends of the said levers will allow the tongues or fingers
to fall into position to be acted upon by the picking cams or strikers and motion
is at such times communicated by the said tongues or fingers to the inclined
shaft and thence to the picking sticks.
The cams give motion at the required times to the lathe through the
intervention of levers f¹ connecting rods f³ and toggle links or levers the
former of which are pin jointed to the lathe swords, whilst the latter are mounted
on the first motion shaft b so as to rock freely thereon.
The picking cams or strikers are fixed on the first motion shaft b which latter
by gearing properly timed (according to the number of shoots of ground weft
required between the shoots of cheuille or fur pile) gives motion to the cam
shaft c.
The cams d, e and are arranged for the insertion of two shoots of ground
weft between every shoot of cheuille or fur pile, they may however be arranged
for the insertion of other numbers of shoots of ground weft after each shoot of
chenille or fur pile.
By the combined arrangement of paris above described we are enabled to give
motion to the healds and picking apparatus and lathe when the chenille or fur pile
inserting apparatus is at rest whilst such parts are kept out of action at the times
when motion is given to the chenille or fur inserting appliances the lathe is
however operated so as to beat up the ground weft and also the chenille or fur pile
at the times required.
According to the second part of our Invention we impart extra falling and
rising motions to the reed for each insertion of chenille or fur in order the better
to ensure the chenille or fur pile being brought up into its proper position. For
this purpose the reed m is operated as described in the Specification of Letters
Patent hereinbefore referred to and as shewn herein at Figure 6 by cams y which

page_text: by levers and connecting links g² give a downward motion to the reed whilst
springs give the upward motion thereto.
On examining the cam y it will be seen that two rises and two falls are given to
the reed mat each revolution of the cam g; as described in the said former
Specification the reed m is caused first to strike the chenille or fur with the
inclined faces of the upper ends m¹ of the reed m (that is when down) and then to
rise so as to stroke up the chenille or fur, the reed retires from the fell of the
work in this position and then in again coming forward it is caused according to
this present Invention to fall and again to strike the chenille or fur with the
upper ends m¹ after which it again rises as it recedes to enable the shuttle to run
across the loom, the reed then falls and again strikes the work when down, after
which it remains down while the lathe goes back to rest in which position, that is
when the lathe is back and the reed down, the fur or chenille is carried across the
loom.
According to the third part of our Invention we employ a fixed reed as shown
at Figures 7 and 8 placed as close as possible to the track of the catcher warp
needles o and of the same gauge as the latter in order to steady the warps and
thereby ensure the said needles entering their proper spaces between the warp
threads.
According to the fourth part of our Invention we impart extra falling motions
and dwells to the catcher warp needles in order to facilitate the setting and
holding of the fur or chenille as it is being brought into its proper position.
For this purpose we employ as described in the said former Specification and
as shown herein at Figure 9 a camp which, by a lever p¹ connecting rod p³ and
lever, gives the rising and falling motions to the catcher warp needles, but
instead of giving merely one rising and two falling motions to such catcher warp
needles o in the full extent of their traverse we employ a cam of the character
shown at Figure 9 which divides the full downward traverse of the catcher warp
needles into three separate falls the first of which carries the catcher warp
needles o down to the position marked (1) Figure 7 that is sufficiently far to
enable the catcher warp to hold the chenille or fur and to remain in such position
while the latter is being adjusted in position and yet permit the weaver readily
to place the selvage thread outside the chenille or fur when the latter is turned at
the selvage; the second fall corries the catcher warp needles down to the position
marked (2) that is sufficiently far to securely hold the chenille or fur in its
adjusted position in which position they remain while it is being beaten and
stroked up.
"
The third full carries the catcher warp needles o down to the position marked (3)
that is to the bottom of the shed where they remain sufficiently long to enable
the shuttle to be thrown across the loom and thereby bind down the catcher warp
and consequently the chenille or fur they then again rise and return to the
position marked (0) where they remain while the chenille or fur is being carried
across the loom.
According to the fifth part of our Invention when it is required to insert an
extra or a floating warp we employ, as shewn at Figures 1 and 10, an extra shaft
or leaf d of healds which we operate by the other leaves or shafts d' or by, some
of them according as it is required to raise such extra shaft or leaf d at the rise
of every heald or at the rise of only certain of them. This we effect by
mounting in sockets or guides at the top of such extra shaft or leaf d one or
more projections de capable of being fixed in position by screw or otherwise so as
to extend over some or all of the other shafts or leaves and thereby cause such
extra leaf or shaft to be raised at the rise of every shaft or leaf or at the
rise of only some of them.
Having thus described the nature of our said Invention and the mode in
which we carry the same into effect we would have it understood that what we
claim is:
First. The combination and arrangement of parts for giving the requisite motions

page_text: and dwells to the lathe, healds and picking motions substantially as herein shown
and described and for the purpose stated.
Second: The employment of means for imparting extra falling and rising
motions to the reed substantially as herein shown and described and for the
purpose stated.
Third: The employment in a loom of the character herein shown and described
of a fixed reed placed as close as possible to the track of the catcher warp needles
substantially as herein shown and described and for the purpose stated.
Fourth: The employment of means for imparting extra falling motions and
dwells to the catcher warp needles substantially as herein shown and described
and for the purpose stated and,
Fifth: The means or apparatus for giving motion to an extra shaft or leaf of
healds substantially as herein shewn and described and for the purpose stated.
In witness whereof I the said William Adam have hereunto set my hand
and seal this twenty third day of December in the year of Our Lord, One
thousand eight hundred and eighty two.
