Improvements in Milling Machines for Milling Textile. Fabrics.
JAMES DIXON ASQUITH, Morley, near Leeds, in the County of Yorkshire,
Machinist, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to dispense with the greater part of the mechanism,
contained inside milling machines, and to also dispense with and substitute other
portions of the mechanism on the outside of such machines, and also to make.
an improved knocking-off board, and mechanism worked in connection with the
knocking-off board. By this invention the whole work of milling fabrics can be
more efficiently done, and the chief working mechanisms being fixed upon the
outside of the machine, there is less liability of their getting out of order, and
when they do get out of order, are more easily and quickly repaired.
In carrying out my object, I make the framework of the machine, in a some-
what similar manner to those in general use. I then fix the necks or bushes of
brass, iron, or other metal, in which the bottom driving shaft, and the top driven
shaft, are to run, inside the machine. I am thus enabled to have the driving
shaft, and the driven shaft, about seven inches shorter than those in general use,
which are now liable, through their length, and the pressure constantly bearing
upon them, to frequent breakages. This shortening of the length of the shafts, in
my invention, reduces the liability to breakages considerably, and has the further
advantage of saving seven inches space occupied by machines generally.
I dispense with the use of the long springs, generally used in connection with
the top driven shaft, and in their places, I fix pads or blocks of india-rubber,
or spiral springs in suitable positions upon the necks or bushes, in which the
top driven shaft runs.
I also dispense with all cog or gear wheels, used generally for driving thẻ
bottom and top shafts, and in their places I fix a flanged wheel upon the bottom
driving shaft, and another flanged wheel upon the top driven shaft, and I also
fix two other flanged wheels upon short shafts, the said shafts being fixed to the
framework, or to castings of iron bolted to the framework of the machine in any
required positions. I then use a rope or round belt, which I carry over, and
around the flanged wheels, in such a manner, that when motion is given to
the bottom driving shaft, the rope or belt, transmits motion to the top driven
shaft.
In my invention I dispense with the pattern of knocking-off board, now in
general use, and I make an improved one of wood, iron, or other suitable.
material, in two parts, an upper and a lower part, these I bolt together, and
they then form, a flat upright surface, through which are a required number of
holes, through which the fabric travels, when the machine is in motion.
In connection with my improved knocking-off board, I make an improved
mechanism for working the slip-box motion or throwing out fork. The two ends
of the knocking-off board, I make to slide in slots, in the sides of the frame-
work, of the machine, in the position now in ordinary use. To the ends of the
knocking-off board, which are put through the said slots, I fix two bars of iron,
which act as horizontal levers, the said bars being fixed one to each end of the
knocking-off board, and outside of the framework of the machine. The bar or
lever on one side of the machine, has its other end put into a slot, in a casting
of iron, the said casting being fixed to the framework of the machine in a
suitable position, below the bottom driving shaft. The second horizontal bar or
lever, has its other end fixed to a short shaft, which shaft is put into the frame-
work on the other side of the machine, in a suitable position, below the bottom

page_text: driving shaft. A third vertical bar or lever is pinned on to the second horizontal
bar or lever, and to the third vertical bar or lever, a fourth horizontal bar or
lever is pinned, and to the fourth horizontal bar or lever, a throwing-out fork,
is fixed in such a position, that it slides upon the bottom driving shaft, backwards
or forwards, to a required distance, when the various bars, or levers, are being
worked by the knocking-off board. The said bars, or levers, are made of any
required dimensions.
Underneath the knocking-off board, I make use of a wooden, iron, or brass
roller, the said roller running in the sides of the framework of the machine, in
such a position, that when the fabric is running through the holes, in the
knocking-off board, it reduces the liability of the fabric, to swing or flap about,
this tendency of the fabric. to swing or flap, often causing it to form into knots.

COMPLETE SPECIFICATION.
Improvements in Milling Machines for Milling Textile Fabrics.
JAMES DIXON ASQUITH, Morley, near Leeds, in the County of Yorkshire,
Machinist, 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 may be clearly understood by referring to Figures 1. 2. and 3.
Figure 1. shows the interior, Figure 2. one side, and Figure 3. the reverse side
of my improved machine.
the
The use or
In carrying out my invention, I make the framework A. A. of the machine in a
similar manner to those in general use. I then fix necks or bushes B2 B and C2 C2
which I make of brass, iron, or other metal (in which the bottom driving shaft B.
and the top driven shaft C. are to run,) inside the framework A. A. of the machine.
I dispense with the use of the long springs generally used in connection with the
top driven shaft C. and in their places, I fix pads or blocks of india-rubber or spiral
springs CC upon the necks or bushes C2 C in which the top driven shaft C. runs.
I place a roller B upon the driving shaft B, and another roller C! upon
driven shaft C. as is the case in the milling machines in general use.
action of the pads or blocks of india-rubber or spiral springs C3 C3 and the use and
action of the rollers B and C are as follows:-The cloth to be milled is put
between the two rollers B and C, and motion being given to the rollers, the cloth
is gradually carried through or between them in the process of milling; whilst this
is going on the cloth has a tendency to get into creases and folds, and has thus a
tendency to drag, and thus runs a risk of being damaged more or less, unless some
means are taken to reduce this risk; when the cloth does get into heavy creases or
folds, the roller C¹ gradually moves or is lifted by them, and the parts of the
shaft C. running in the necks or bushes C C upon which the roller C is fixed,
press against the pads or blocks of india-rubber or spiral springs C³ C³, in such a
manner that the roller C¹ rises sufficiently as to allow the cloth to run freely
between the rollers B and C. When the folds or creases in the cloth decrease,
the reverse operation takes place, and the roller C¹ gradually resumes its normal
position.
-
1 dispense with all cog or gear wheels used generally for giving motion to the
top driven shaft C. and in their places I fix, as shewn in Figure 3. a flanged
wheel B upon the bottom driving shaft B. and another flanged wheel C upon the
top driven shaft C. and I also fix two other flanged wheels 135 C upon short shafts;
the said shafts being fixed to the framework A. A. or to castings of iron bolted to
The said framework of the machine, in any required position. In connection

page_text: with the said flanged wheels, I use a rope, belt, or chain, which I carry over or
around the flanged wheels, as indicated by the dotted lines in Figure 3. that when
motion is given to the bottom driving shaft B. motion is transmitted to the top-
driven shaft C. I dispense with the pattern of knocking-off board now in general
use, and I make one of wood, iron or other suitable material, in two parts D1 D'
and these I bolt together, they then form a flat upright or horizontal surface,
having a required number of holes, through which the fabric travels, when the
machine is in motion. In connection with the knocking-off board, I make an
improved mechanism for working the throwing out fork, and slip-box motion. The
two ends of the knocking-off board D'D' I make to slide in slots in the sides of
the framework A. A. of the machine, in the position now in ordinary use. To the
ends of the knocking-off board, which are put through the said slots, I fix two bars
of iron D D³ which act as horizontal levers, the said bars D³ D³ being fixed one
to each end of the knocking-off board D¹ 12 and outside of the framework A. A. of
the machine. The bar or lever D³ on one side of the machine, has its other end
put into a slot in a casting of iron, which is fixed to the framework A. of the
machine as in Figure 3. in a. suitable position below the bottom driving shaft B.
The second bar or lever D' on the other side of the machine, as shewn in Figure 2.
has its other end fixed to a short shaft A' which shaft is put into the framework of
the machine in a suitable position below the bottom driving shaft B. A third
vertical bar or connecting rod D is fixed on by a moveable joint to the second
bar D and to the bar or rod D' a fourth bar or lever D is fixed by a moveable
joint, the other end of the bar or lever D³ is fixed to one end of a short shaft Do
the said short shaft De working in a barrel casting D' which casting is fixed to the
framework of the machine A. To the other end of the short shaft D a throwing-
out fork D is fixed. On the shaft B the slip box motion D. is fixed, the latter
slides upon the driving shaft B. backwards or forwards to a required distance, when
the various bars or levers, are being worked by the knocking-off board. The said
bars or levers, are made of any required dimensions, or of any suitable metal.
The working of the throwing-out fork and slip-box motion, by the knocking-off
board is as follows:-When a length of cloth is being run between the rollers B₁C₁
and then through the holes in the knocking-off board, there is always a risk of the
cloth forming occasionally into a knot, when this occurs, the strain or drag of the
running cloth upon the knocking-off board, lifts it and this lifting causes the various
bars or levers connected with the throwing-out fork D, to act upon the throwing-
out fork D, that it moves towards the framework of the machine A, and away from
the driving pulley E, causing the slip-box motion D, to come out of gear with the
pulley E, as the slip box motion D is made to slide by the action of the throwing-
out fork D, also towards the framework A of the machine, and away from the
pulley E. When the pulley E. has been brought out of gear with the slip box
motion D. it runs loose upon the shaft B, and thus the machine stops running.
When a knot which has formed in the cloth is loosed, the knocking-off board drops, and
the various parts named in connection with it, go through a reverse movement, and
the machine is set running again.
I do not confine myself to any special pattern of slip-box motion that illustrated
in Figure 1. being in preference used to others. D. being a loose casting upon
the shaft B. being made to slide backward and forwards. D D being two studs
of a required length. D is a casting fastened on to the shaft B, having two holes
in positions corresponding to the positions of the said two studs. The action of the
motion is as follows:- When the casting D. slides on the shaft B towards the
pulley E. the studs D' D' move through the holes in the casting D10 such a distance
that they come into contact with the pulley E. by the arms of the pulley coming in
contact with them, the running pulley thus causes the shaft B to revolve, when the
reverse movement of the casting D. takes place, the studs D° D° recede from the
pulley E. and thus it runs loose on the shaft B. and the machine stops running.
Motive power is given to the machine, as to those general use, by a belt from
the main shaft, upon the pulley F.

page_text: 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:
1. In machines for milling textile fabrics, the use of the necks or bushes inside
the framework of machines as described.
2. In machines for milling textile fabrics, the use of the wheels B**B* C* C*
driven by means of a rope, chain or belt as described.
3. In machines for milling textile fabrics, the use of india-rubber pads or spiral
springs C3 C3 upon the top part of the necks or bushes C² C² as described.
4. In machines for milling textile fabrics the use of the knocking-off board D¹ D'
as described.
5. In machines for milling textile fabrics, the use of the several horizontal and
vertical bars or levers, in combination with the knocking-off' board, and the
throwing-out fork as described.
