IMPROVEMENTS IN APPARATUS FOR BOILING AND BETTING WOVEN FABRICS
Year: 1884

page_text: We, ISAAC HENRY BOTTOMLEY and THOMAS BOTTOMLEY both of Clough Mills,
Shelf near Halifax in the County of York Manufacturers, do hereby declare the
nature of our invention for IMPROVEMENTS IN APPARATUS FOR BOILING AND
BETTING WOVEN FABRICS to be as follows
-
The object of our invention is to arrange an apparatus in such a manner that it
will be applicable for the combined operations of stretching, tentering, boiling and
setting woven fabrics
We accomplish our object in the following manner we form a deep vessel or
Cistern with an open top and mount therein two shafts upon which are placed
adjustable chain pullies which can be regulated to the varying distances required
by the pieces of fabric when boiled and set. At some distance from the said vessel
or cistern we mount another shaft upon which we place pullies that are adjustable
also these are secured on to the shaft to the width of the fabric when woven, and
which is placed upon tentering pins secured to chains and the machines started
These chains run in suitable grooves and over the pullies in the vessel which are
expanded to the width it is required to stretch the piece After passing over the
first pair of expanded pullies the chain and fabric are conducted through boiling
liquor, passing round in a stretched condition curved grooved slides at the bottom
and up over the second pair of pullies, to stripping rollers on the outside, by which
operation the fabric is stretched between the feeding pullies and first pair in the
vessel, and then boiled and set whilst passing through the vessel.
Or in place of the chain pullies inside the vessel or cistern the grooved slides
may be continued from the first or feeding pullies through the cistern and back
again to the feeding pullies

Shelf near Halifax in the county of York Manufacturers do hereby declare the
nature of our invention for IMPROV FMFNTS IN APARATUS FOR BOILING AND
BETTING BOVEN FABRICS 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 our invention is to arrange an apparatus in such a manner that it
will be applicable for the combined operations of stretching tentering boiling and
Betting woven fabrics and consists in forming a deep vessel or cistern with an
open top and mounting therein adjustable guides in the grooves of which are
placed traversing chains fitted with tentering pins, and at some distance from the
said vessel or cistern we mount a shaft upon which adjustable chain pullies are
placed for giving motion to the said chains.
The fabric is fed on to the tentering pins near the chain pullies, and passing
through the boiling liquor in a stretched condition, 18 boiled and set, so that
when stripped off the pius by the stripping rollers it retains the width at which it
has been set
.
In the accompanying drawings Fig 1 represents a side elevation of our improved
apparatus. Fig 2, is a plan of the same Fig 3 18 a sectional elevation through
line A, B and the remainder of the figures are enlarged details In all the figures
similar letters indicate similar parta.
The apparatus 18 driven by the revolving shaft upon which the pinion A 18
secured the latter gearing into the teeth of the wheel B on the main shaft C, upon
which are mounted the two sliding chain pullies D, and D' Around each of
these pullies is an endless pitch chain E, having tentering pins I fixed to the
projecting tlanges F The links of the respective pitch chains after leaving the
pullies D and D', pass through the grooved slides G and G which extend down
into the vessel or cistern and back again to the said pullius, both guides and
pullies being capable of adjustment side ways to suit the width of the fabric to
be boiled and "aet"
The grooved slides G, and G¹ are connected together in several places by
screws S, one portion of each screw from the centre towards the end being cut
with a left hand thread, and the other portion with a right hand thread each
screw being coupled together by shafts II and wheels I and II so that by
turning the handle J all the screws are actuated at the same time thereby
causing the grooved slides G and G' to travel towards or from each other according
to the direction in which the said handle is turned
In connection with the top screw S¹ are two arms K, one being on the left hand
portion of the screw and the other on the right hand, by which the pitch chain
pullies D, and D', are moved in the same direction and at the same time as the
grooved slides. These are set a little further apart at L L than where the fibrio
19 fed on to the tentering pins at M, M, by which the tabuc 18 stretched and 18

page_text: conducted at that width through the boiling liquor by which it is set, and finally
stripped from the tentering pins by the rollers N and N¹ and wrapped around the
roller N
In order that the tentering pins may get properly hold of each edge of the fabric
as it is fed to the machine, we secure to each grooved slide a bracket P and joint
to each a lever one arm R, of which is fitted with a circular disc T, covered with
india rubber or felt or a strong circular brush may be used for the purpose of
pressing the said pins through each edge of the fabric, the necessary pressure
being obtained by the adjustable weight Ŵ on each arm R₁ of the said levers
The pitch chains E are assisted through the grooved slides G and G¹ by two
small pitch chain pullies D' and D³ on the revolving shaft C' the teeth of which
engage with the links of the said chains and thereby assist in moving the chains
through the grooves
Instead of having continuous grooves as shewn and described, adjustable pullies
may be used at the angles for the chains to pass over, but this arrangement is not
so simple in construction as the one herein before described because the right and
left hand threaded screws S, cannot be connected direct with the pullies as is the
case with the grooved slides shewn at Y If pulhes are used at the angles aims
somewhat like K, in connection with the pullies D and D¹ must be employed to
connect the screws and pullies, so that the said pullies may be moved on the shafts
to suit the various widths of fabric to be stretched and set the liquor in the
vessel being heated by steam or by any other well known method
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim 18
The passing of fabrics in a stretched condition through a vessel containing
boiling liquor all being arranged substantially in the manner and for the purpose
shewn and described
