PROVISIONAL SPECIFICATION.
Improvements in Burl-dyeing Machines.
JAMES DIXON ASQUITH, Queens Mills, Morley, Yorkshire, Machinist, do hereby
declare the nature of this invention to be as follows:-
The object of my invention is the construction of an automatic reversing mechanism
for burl-dyeing machines, or what are often termed "weejee" machines. In this
class of machine, when the fabric has to be dyed, it is put upon a roller at one side
of the vessel which contains the liquid dye, and from the said roller it is unwound on
to another roller on the opposite side of the machine. When undergoing this opera-
tion, the fabric passes under guide rollers immersed in the dye vessel. After the
fabric has been unwound from one roller to the other, an attendant by operating a
clutch throws the winding on roller into gear with a positive driving mechanism, and
this causes the motion of the two rollers to be reversed, and in consequence the fabric
is wound the reverse way. This operation is repeated, until the fabric has been
sufficiently dyed. In carrying out my invention, I make the clutch self-acting so
that the services of an attendant are dispensed with, and in carrying out my object
1 fix a shaft of iron (which runs) across the centre of the machine, and to which
shaft I fix three cast or wrought iron arms, one of the said arms operating the clutch:
and to the other two said arms I attach bearings and slide rods and two "upper
rollers, the said upper rollers working on the fabric as it wraps round the roller at
one side of the machine in such a manner, as to a cause a reversal of the rollors, and
rewind the fabric on to the roller at the opposite side of the machine. The two
upper rollers are fixed by their ends on to cast or wrought iron bars, the said bars
sliding through two boxes, the said boxes being fixed upon upright arms,
these arms
are keyed or fastened (one at each end of the machine) to the above mentioned iron
shaft which runs across the centre of the machine. The boxes are moveable, and are
made to slide up or down the upright arms, so as to suit different lengths of fabrics
that have to be wrapped upon the rollers. The boxes are adjusted by means of a
screw. To the friction pulleys which are usually attached to the rollers upon which
the fabric is wound I fix an improved brake, the said brake consisting of half the
usual friction straps to each roller, the bottom part of which I make fast, and to the
upper part I fix an iron rod which regulates the brake automatically.

Improvements in Burl-dyeing Machines.
JAMES DIXON ASQUITH, Queens Mills, Morley, 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:-
The object of my invention is the construction of an automatic reversing mechanismı
for burl-dyeing machines, or what are often termed "weejee" machines. In this
class of machine, when the fabric has to be dyed, it is put upon a roller at one
side of the vessel which contains the liquid dye, & from the said roller it is unwound
on to another roller on the opposite side of the machine. When undergoing this
operation, the fabric passes under guide rollers immersed in the dye vessel. After
the fabric has heen unwound from one roller to the other, an attendant by operating
a clutch throws the winding on roller into gear with a positive driving mechanism,

and this causes the motion of the two rollers to be reversed, and in consequence the
fabric is wound the reverse way. This operation is repeated until the fabric has
been sufficiently dyed. In carrying out my invention 1 make the clutch self-acting,
so that the services of an attendant are dispensed with, and in carrying out my
object I fix a shaft of iron (which runs) across the centre of the machine and to
which shaft I fix three cast or wrought iron arms, one of the said arms operating the
clutch; and to the other two said arms I attach bearings and slide rods and two
upper" rollers, the said upper rollers working on the fabric as it wraps round the
rollers at one side of the machine, in such a manner as to cause a reversal of the
rollers, and rewind the fabric on to the roller at the opposite side of the machine.
The two upper rollers are fixed by their ends on to cast or wrought iron bars, the
said bars sliding through two boxes, the said boxes being fixed upon upright arms;
these arms are keyed or fastened (one at each end of the machine), to the above
mentioned iron shaft which runs across the centre of the machine. The boxes are
moveable, and are made to slide up or down the upright arms, so as to suit different
lengths of fabrics that have to be wrapped upon the rollers. The boxes are adjusted
by means of a screw. To the friction pulleys which are usually attached to the
rollers, upon which the fabric is wound, I fix an improved brake, the said brake
consisting of half the usual friction straps to each roller the bottom part of which I
make fast, and to the upper part I fix an iron rod which regulates the brake auto-
matically.
Figure 1. is a section of the end of the machine, A, A is the dye vessel, A¹ is the
upright arm which is fastened to the iron shaft running across the centre of the
machine, B, B are the rollers upon which the cloth is wound and re-wound, during
the operation of dyeing, C, C are the two "upper" rollers fixed upon slide rods D.
E shows the box at one end of the machine through which the bar D slides. The
boxes E, are moveable, being made to slide up or down the upright arm A¹ in order
to suit various lengths of fabrics. At the opposite end of the machine to the section
described, there is the corresponding upright arm A¹ the opposite ends of the
rollers B, B, C, C, the slide rod D, and the moveable box E. When the machine is
put into operation one end of the fabric is wound upon roller B¹ which is put into the
machine; the fabric is carried under rollers F, F', and up to roller B, to which it is
fastened. The rollers B, B¹ run in bearings that are fastened to each end of the
machine, and when the machine is in motion they work independently of the sliding
rollers C, C, being employed for the fabric being wound upon them, backwards and
forwards during the process of dyeing. H, is the horizontal bar running across the
machine, and to this is keyed a short upright arm I, to which is fastened a bar or
connecting rod J, the said bar J being attached at the ends to arms K2, K³, the said
arms K2, K³, working the clutch boxes K; K¹. A shaft L having a bevelled wheel
on each end M, M', which work into bevelled wheels on the ends of rollers B, B¹, is
made to revolve in a suitable manner. When the machine is in motion the fabric
is unwound from roller B¹, and wound upon roller B, and whilst this operation is
going on,
the fabric gets gradually thicker upon roller B, and it begins to press upon
roller C, causing the slide D to gradually move through the box E, carrying with it
the rollers C, C, until they reach the points G, G¹, when the pressure put upon the
upright arm A causes it to move forwards gradually towards roller B', and this
movement of the upright arm A¹ turns the horizontal shaft H slightly, and this
gradually causes the short arm I to move in the direction of roller B₁ a. required
distance, carrying with it the bar J, this causes the arm K' to move forward the
clutch K, and puts it into gear with wheel M, which it locks fast upon the shaft L;
whilst this is going on, the clutch K has been taken out of gear by arm K³, and
wheel M is at the same time let loose upon shaft L. This reversing of the mechanism
causes the rollers B, B₁ to revolve the reverse way, and the fabric is rewound on to
the roller B'. This reversing of the mechanism goes on until the process of dyeing
is completed.
The wheels M, M run loose on the shaft L, until they are alternately put into
gear with clutches K, K¹, when the one in gear is locked fast upon the shaft L, and

page_text: the other one runs loose. The motive power is given to the machine by pulley N,
fixed upon the shaft L-the pulley N being driven by strap 0.
Having now particularly described and ascertained, and in what manner the same
is to be performed, I declare that what I claim is :-
the other one runs loose. The motive power is given to the machine by pulley N
fixed upon the shaft L-the pulley N being driven by strap 0.
Having now particularly described and ascertained, and in what manner the sam
is to be performed, I declare that what I claim is :-
1. The moveable slide box E upon the upright arm A.
2. The two upper rollers C, C¹ in combination with the slide rod D.
