ROBERT NUDDS HAVERS and ROBERT GICHARD GEACH, both of Bradford, in the
County of York, Manufacturers. "IMPROVEMENTS IN THE METHOD OF AND
APPARATUS FOR CUTTING CHENILLE CLOTH."
The object of our Invention is to cut by means of machinery cloth made of
cotton, wool, silk, mohair, or any other fibre or combination of fibres that are used
in the manufacture of dress piece goods in such a manner that the strips, ends,
threads, or strands of cloth that are cut will be what is commonly known as
chenille, which can be used for the warp or weft, as the case may be, for fancy
piece goods.
We accomplish our object in the following manner:-We construct a frame of
metal or wood; at the back of this frame, and centred in suitable journals, is
mounted a circular beam or roller, which is weighted in a similar way to the back
beam of the ordinary loom. At the top of the before-named frame and at the front
side of the same we secure two brackets, which project towards the back of the
frame. In these brackets is mounted a spindle, which contains a number of circular
cutters or knives which are capable of being regulated to the pitch of the warp of
the cloth to be cut. This spindle and the revolving knives receive motion by means
of a pulley which is secured on the spindle, and is in connection with a pulley
that is fixed to the main shaft of the machine. At the front of the frame
we fix rollers or beams similar to the front beams of the ordinary loom, which are
actuated by means of a strap or gearing in connection with the main shaft of the
apparatus. The cloth to be cut is placed on the back beam, and is passed over a
guard that is fixed between the knives and the back beam. This guard is capable

page_text: of being regulated according to the diameter of the knives in such a manner that
when the fiont rollers to which the piece is attached, and which are actuated as
before described, draws the cloth round its circumference, the revolving knives cut
the same into strips, and thus the weft of the cloth which projects from the centre
threads of warp forms the chenille.
.
In order to keep the warp of the cloth in a streight line, and to cut the weft of
the piece at the required distance from the centre thread or warp, we fix a bar to
the before-named brackets. On this bar we place a number of small pullies, which
have projections on the circumference; this bar is capable of being regulated in
elevation so that the V projections will pass through the weft until the sides of the
V's are near to the centre thread or warp. The selvage of the piece is formed in a
fold or pocket the whole length of the piece. Into these pockets at each side of the
piece wo place a bar which keeps the piece stretched tight and in position before it
passes over the knives to be cut, after which the strips or threads pass through
guards that aro fixed close to the revolving knives, and thus by these means the
cloth is kept in a streight line, and the yarn of the same is cut uniformilly at the
required distance from the centre thread or warp of the piece.
We can also arrange our apparatus so that we can use straight or curved knives
in place of the circular knives before described; these knives are secured to a bar
which works in a slide or groove, and are actuated by means of a cam or tappet,
which moves the knives in a vertical or circular motion, and thus cuts the yarn of
the piece, and forms the chenille, as before described.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Robert Nudds Havers and Robert Gichard Geach in the Great Seal
Patent Office on the 12th June 1878.

The object of our Invention is to cut by means of machinery cloth made of
cotton, wool, silk, mohair, or any other known fibre or combination of fibres that 3
are used in the manufacture of dress piece goods in such a manner that the strips,
ends, threads, or strands of cloth that are cut will be what is commonly known as
chenille, which can be used for the warp or weft, as the case may be, for fancy piece
goods.
We accomplish our object in the following manner :- -We construct a frame of 3
metal or wood, at the back of this frame, and centred in suitable journals, is
mounted a circular beam or roller, which is weighted in a similar way to the back
beam of an ordinary loom. At the top of the before-named frame, and at the front
side of the same, we secure two brackets which project towards the back of the
frame. In these brackets is mounted a spindle, which contains a number of circular 4
cutters or knives, which are capable of being regulated to the pitch of the warp of

page_text: he cloth to be cut. This spindle and revolving knives receive motion by means of
pulley which is secured on the spindle, and is in connection with a pulley that is
ixed to the main shaft of the machine. At the front of the frame we fix rollers
or beams similar to the front beams of an ordinary loom, which are actuated by
neans of a strap or gearing in connection with the main shaft of the apparatus.
The cloth to be cut is placed on the back beam, and is passed over a guard that is
ixed between the knives and back beam; this guard is capable of being regulated
according to the diameter of the knives in such a manner that when the front
rollers to which the pieco is attached, and which are actuated as before described
draw the cloth round the circumference of the bottom roller, the revolving knives
cut the same into strips, and thus the weft of the cloth which projects from the
centre threads of warp forms the chenille.
In order to keep the warp of the cloth in a straight line, and to cut the weft of
the piece at the required distance from the centre thread or warp, we fix a bar to
tho before-named brackets. On this bar we place a number of small pullies, which
have V projections on the circumference, this bar is capable of being regulated in
elevation, so that the V projections will pass through the weft until the sides of
the V's are near to the centre threads or warp. The selvage of the piece is formed
in a fold or pocket the whole length of the piece. Into these pockets at each side
of the piece we place a bar, which keeps the piece stretched tight and in position
before it passes over the knives to be cut, after which the strips or threads pass
through guards that are fixed close to the revolving knives, and thus by these
means the cloth is kept in a straight line, and the yarn of the same is cut uniformly
at the required distance from the centre thread or warp of the piece.
We can also arrange our apparatus so that we can use straight or curved knives
in place of the circular knives before described; these knives are secured to a bar
which works in a slide, groove, or centred on a shaft or spindle, and are actuated
by means of a cam or tappet, which moves the knives with a vertical or circular
motion, and thus cuts the yarn of the piece and forms the chenille, as before
described.
In order that our Invention may be better understood we have appended
Drawings that illustrate such portions of the apparatus as are required to ellucidate
the same.
The apparatus is shewn in the accompanying Drawings in front elevation at
Figure 1;
in side sectional elevation at Figure 2; in plan at Figure 3.
Figure 4 shows an enlarged side elevation of the circular knives and guide
pullies.
Figure 5 is a plan of the same.
Figure 6 is a side sectional elevation of our apparatus, which shews a modified
method of cutting the cloth.
Figure 7 is an enlarged view, shewing the oscillating knife or cutter.
Figure 8 is a plan of the same.
Similar letters and figures represent similar parts in all the Figures.
A, A, is the framing of the machine; B is the main shaft, to which motion is
imparted by means of a strap in the ordinary manner; C is the back beam which
contains the cloth to be cut; the cloth D is conducted in the direction of the arrows
over roller E and adjustable guard F; this guard is fixed to projecting brackets G
that are secured to the front top rail of the apparatus; H, H, are vertical brackets,
in which is mounted a bar H' that contains a number of small pullies J, which
have thin V projections on the circumference; these pullies are capable of being
regulated to suit the pitch of the warp in the cloth to be cut into chenillo; the
elevation of these pullies is adjustable in order that the V's will pass through the
weft such a distance that the sides of the V's are brought near the warp of the
cloth, so that the cloth will travel in a straight line, and the warp will be the proper
distance from the knives or cutters; K is the knife spindle, on which are fixed the
circular knives K'. On the end of this spindle is pulley L, which is in connection
with pulley M on shaft B; the bars N are secured to the top of front rail N¹, and the

page_text: enda O are placed into the pockets formed in the selvage of the cloth; to each of
these bars is attached a spiral spring N2, for the purpose of keeping the cloth
stretched in a transverse direction before it is cut by the circular knives. When
the cloth passes over the knives k¹, and is thereby cut, it travels through the guides
P fixed to the top rail N¹ (or in any convenient position between the same, and the
revolving cutters or knives K¹) to the front roller R, which is actuated from main
shaft B through pullies S and S¹ and train of gearing T; thus, by the front beam R
revolving the cloth is drawn from the back roller C in the direction before described,
and cut by the revolving knives into strips, which may be used for the warp or weft
for fancy dress goods.
Figures 6, 7, and 8 shew our modified arrangement for working the knives or
cutters. U a cam or eccentric fixed on shaft B; this eccentric is connected by
means of rod U¹ to one end of the lever X, which is secured on end of spindle K,
on which the eutters are also secured, so that by the action of the revolving
eccentric an oscillating motion is imparted to the knives or cutters, which cut the
weft of the cloth as it travels from the back roller to the front roller, as before
described.
Having thus described our said Invention, and the manner in which is or may
be performed, we have to state that we do not confine ourselves to the precise
details herein described and delineated, but that what we believe to be novel and
original, and claim as our Invention is, the arrangement and combination of the
various parts of the apparatus for adjusting and regulating the cloth before it is
passed over tho knives to be cut, so that the warp of the same is kept in a straight
line and at an uniform distance from the centre of the cutters or knives, substan-
tially in the manner herein-before described, and illustrated by the accompanying
Drawings.
In witness whereof, I, the said Robert Nudds Havers, for and on behalf of
myself and the said Robert Gichard Geach, have hereunto set my hand and
seal, the Seventh day of June, in the year of our Lord One thousand
eight hundred and seventy-eight.
Signed and sealed by the before-named
Robert Nudds Havers in the presence
