IMPROVEMENTS IN MACHINERY EMPLOYED IN BEAMING AND DRESSING WARPS
Year: 1884

page_text: I, JOHN WILLIAM BLAKELEY, of Birstall, near Leeds, Yorkshire, Machine
Maker, do hereby declare the nature of my invention for "IMPROVEMENTS IN
MACHINERY EMPLOYED IN BEAMING AND DRESSING WARPS," to be as follows:-
My Invention has reference to that class of machinery employed in dressing
warps after any of the processes of sizing, dyeing or bleaching or other process
which causes the threads to adhere or stick to each other.
In this class of machine the warp is caused to travel from one beam to another,
or from the "ball" to a warp beam; the object of my Invention is to dress the
warp as it is travelling in the manner mentioned; to accomplish which I employ a
number of brushes (the full width of the warp) which are connected at each end to
two or other number of endless travelling chains or belts, which travel in an
opposite direction to the warp, and as the brushes penetrate and pass through the
warp, it is brushed and dressed thereby, previous to being wound upon the warp
beam.
By these means all the threads which were sticking together are loosed, and.
made free.
The second part of my Invention relates to the means to be employed for
stopping the machine, when there are any knots in the warp too large to pass
through the reed.
As is well known the reed is connected to lever-arms capable of oscillating at
their lower ends, and when there are knots on the warp too large to pass through
the dents of the reed, the said lever arms are caused to oscillate.
To carry out my Invention I employ a lever attached to a rod in connection
with the strap-fork, so that when there are knots on the warp, too large to pass
through the reed, the lever arms are caused to oscillate, and in so doing they
strike the lever which draws the rod out of contact with the strap-fork rod,
whereby the driving strap is transferred from the fast to the loose pulley.

do hereby declare the nature of my invention for "IMPROVEMENTS IN MACHINERY
EMPLOYED IN BEAMING AND DRESSING WARPS," and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:―
My Invention bas reference to that class of machinery employed in dressing
warps after any of the processes of sizing, dyeing, or bleaching or other process
which causes the threads to adhere or stick to each other.
In this class of machine the warp is caused to travel from one beam to another,
or from the "ball" to a warp beain, the object of my invention is to dress the
warp as it is travelling in the manner mentioned, to accomplish which I employ a
number of brushes (the full width of the warp) which are connected at each end
to two or other number of endless travelling chains, or belts, which travel in an
opposite direction to the warp, and as the brushes penetrate and pass through the
warp it is brushed and dressed thereby previous to being wound upon the warp
beam. 1
In order that my Invention may be more fully understood I have hereto
annexed two sheets of drawings illustrative thereof, wherein Fig 1 is side clevation
of a machine for beaning and dressing warps, and Fig 2 is the same elevation in
section on a larger scale. The warp after any of the processes of dyeing, sizing, or
bleaching is placed in the ordinary manner onto the table A, which is capable of
revolving upon an axis.
From this table the yarn passes over and around the guide rollers B whereby
the warp is distributed to the full width of the warp beam, and taken over the
cross rail C and under the cross-rail D, both of which are attached at each side to
the standard E. The warp then travels horizontally and in its forward novement
comes in contact with the brushes F which are travelling in an opposite direction
to the warp; such brushes penetrating and passing through the warp, whereby it
is brushed and dressed, and all threads that may be sticking together are loosed
and made frec.. The warp is then divided, one part passing over, and the other
part under the vibrating bar G, and thence to the warp beam H. It will be seen
on reference to the drawings that the brushes are attached at each side of the
machine to the travelling chains I passing around two discs I', I³, the discs I'
unning loosely on short studs fixed to, the framing, but the toothed discs I are
keyed onto the shaft J which shaft is driven by pulleys and cross strap J' from
main driving shaft K. Suitable guide plates a are employed to keep the brushes
steady and to prevent them from vibrating. The bar G receives a vibratory
motion by means of the rods and bell crank levers L from the face plate L'
fastened on the shaft L which receives its motion from bevil gearing and diagonal
shaft L³ as shewn in Fig 2.
The second part of my Invention relates to the means to be employed for
stopping the machine when there are any knots in the warp too large to pass
through the reed.

page_text: This part of my Invention is shewn in Fig 2 where K₁ are the main driving.
pulleys, and K³ a cam fastened on the main driving shaft K. This cam works in
the clip or horse shoe K³ one end of which is attached to the vertical spindle M to
which it gives a rising and falling motion, the other end Mt which also forms the
fulcrum for the shaft K to work upon, is attached to a vertical spindle M². N is
the rod on which the strap guides N' are fastened, the said rod having a recess or
notch b made therein in which rests one end of the lever arm N such lever arm
being kept in the notch by the spiral spring g O is a rod supported by brackets
010, and provided with a projecting casting 0³ on its upper side. P is an
ordinary reed supported by the upright rod P and fastened onto the shaft P² to
which an oscillatory motion is given by the cam P³ operating the short arm P
fixed to the shaft P2 and on the shaft P' is a'so fixed another arm Q.
The mode of operation is as follows,-When any knots or other irregularities in
the warp come up against the reed P and are too large to pass through the dents
in the reed, the drag thereon would oscillate the upright rod P' bringing the
arın Qinto contact with the casting 0³ which it would push forward taking the
rod O with it in the direction of the arrow c the effect of which would be to push
the lever R until its opposite end came over the vertical spindle M shown more
clearly in plan view Fig 3.
The vertical spindle M has a continuous upward and downward motion given to
it by the rotary cam K' but as soon as the lever R is placed on the said vertical
spindle M its upward motion is stopped, but as the can continues to revolve it
throws up the other spindle M2 whereby the cap d on the top thereof lifts up the
lever arm N2 in such manner as to remove its front end out of the notch bin the
rod N which when thus liberated is immediately caused to slide endwise by
the spiral spring S so as to remove the strap from the fast pulley to the loose one,
whereby the machine is at once stopped. As soon has the spindle M2 has been
lifted and removed the arm N2 from the notched bar, the spiral spring f forces the
spindle M back again.
The strap is placed onto the fast pulley again by twisting a vertical rod T which
causes the bell-crank lever T¹ on the bottom thereof to slide the rod N in its
bearings against the pressure of the springs.
The warp beam H is driven by a train of gearing U in the ordinary manner.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
Firstly In warp dressing machines the employment of endless travelling chairs
for carrying the brushes F in manner substantially as herein shewn and described. "
Secondly The means herein shewn and described for automatically stopping
the machine when any knotted warp cannot pass through the dents of the reed.
