Improvements in Steam Pipes Employed for Heating and Bolling
Sizeing, Dye Liquor, Water, or other Liquors.
I, THOMAS WINTER of Perseverance Works, St. Peter's Street, Blackburn in the
County of Lancaster, Machinist, do hereby declare the nature of this invention to be
as follows:-
This invention relates to appliances for purposes aforesaid, wherein steam is the
heating medium, discharged through perforations or holes, made through steam pipes,
such pipes being coiled, or otherwise shaped, in order to adapt then to particular
positions, or to the form of the vessel containing liquor, the bending or coiling in
many cases, amounting to a material part of the entire cost of such pipes, and which
are rendered no longer serviceable, when the holes or perforations become, through
use, enlarged.
The object of this invention is to remedy the defect referred to, and render the pipes
permanently useful which I effect as follows:-
According to this my said invention I employ in combination with the steam
supply pipe or pipes, discharge nozzles (preferably of brass) these are affixed in the
pipe or pipes, by screw thread and holes, that is, the pipe is bored and tapped, and
the nozzle is screwed in so that when worn or enlarged, through use, they may
readily be replaced, by new nozzles, and the pipe or pipes are practically renewed,
and by reason of the facilities for replacement, any hole through wear, or other defect,
giving off more than its due proportion of steam, will be replaced by a new nozzle,
so as to equalize the supply of steam, to all parts of the liquor containing vessel,
thereby economizing, and fully utilizing the supply of steam, and avoiding the waste
and unequal results, following or arising from unequalities of size of holes, bored
through the pipes and worn as heretofore.
In practice I have found it advantageous the holes through the nozzles, should be
conical, they may however be of other forms and of size, according to the special
requirement or use to which the steam pipes are to be applied.

COMPLETE SPECIFICATION.
Improvements in Steam Pipes Employed for Heating and Boiling
Sizeing, Dye Liquor, Water, or other Liquors.
I, THOMAS WINTER, of Perseverance Works, St. Peters Strect Blackburn, in the
County of Lancaster, 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 :-
This invention relates to appliances for purposes aforesaid, wherein steam is the
heating medium, discharged through perforations or holes, made through steam pipes,
such pipes being coiled, or otherwise shaped, in order to adapt them to particular
positions, or to the form of the vessel containing liquor, the bending or coiling in
many cases, amounting to a material part of the entire cost of such pipes, and which
are rendered no longer serviceable, when the holes or perforations become, through
use enlarged.
The object of this invention is to remedy the defect referred to and render the
pipes permanently useful which I effect as follows.
According to this my said invention I employ in combination with the steam supply

page_text: pipe or pipes, discharge nozzles (preferably of brass) these are affixed in the pipe or
pipes, by screw thread and holes, that is, the pipe is bored and tapped, and the nozzle
is screwed in so that when worn or enlarged through use, they may readily be
replaced by new nozzles, and the pipe or pipes are practically renewed, and by reason
of the facilities for replacement, any hole through wear, or other defect, giving off
more than its due proportion of steam, will be replaced by a new nozzle, so as to
equalize the supply of steam, to all parts of the liquor containing vessel, thereby
economizing and fully utilizing the supply of steam, and avoiding the waste and
unequal results, following or arising from unequalities of size of holes, bored through
the pipes or worn as heretofore.
Such being the nature and object of this my said invention, the following is a
complete discription of same, reference being had to the accompanying drawings
is which:-
Fig. 1 is a plan view of a vat, for size, or die liquid, in which is a steam pipe
bent to the required shape, and having the metal nozzles inserted, by which nozzles
the steam is to escape.
Fig. 2. is a side elevation of one of the "nozzles " drawn about twice size.
Fig. 3. is a plan view of Fig. 2.
Fig. 4 is a sectional elevation of Fig. 2.
According to this my said invention the steam pipes 1 are bent as required or so
as to fit in the boiler or vat 2 as ordinary, but in lieu of simply drilling or other-
wise forming holes in the said pipes 1 I first drill holes therein which are then
tapped so as to receive a nozzle 3 of metal (preferably brass) which has a screw
thread 4 chased thereon which thread is received in the tapped hole formed in the
steam pipe 1, so that if one of the nozzles 3 become worn or its orifice enlarged
through use, the same may be removed and readily replaced by a new nozzle and
thus the pipe or pipes 1 are practically renewed, and by reason of the facilities for
replacement, any hole through wear, or other defect, giving off more than its duo
proportion of steam, will be replaced by a new nozzle 3 so as to equalize the supply
of steam, to all parts of the liquor containing vessel 2, thereby economizing, and
fully utilizing the supply of steam, and avoiding the waste and unequal results,
following or arising from unequalities of size of holes, bored through the pipe 1 or
worn as heretofore. The nozzles 3 are bored or drilled internally (see Fig. 3) at
each end in the form of a cone 5. 6 the apexes of which, meeting in the centre
form a passage way or hole through the nozzle 3 by forming the orifices in the
nozzles in this way the holes or orifices are not so liable to be closed or
filled up with size when the steam is turned off and the size cools, caking
in the orifices, the force of steam when turned on being concentrated at the
apex of the inner cone 5 will blow the size or other obstruction out of the
outer cone 6 thus clearing the orifice. The size and shape of the orifices 5. 6 can
of course. be varied according to circumstances and according to the capacity of
required discharge, but the shape of orifice shewn and described I have found most
effective in practice.
It is well known that in apparatus of this discription when the steam is shut off
from the discharge pipes 1 a vacumn is formed in such pipes and into such vacumn
size or dye is drawn and by the heat of the pipes 1 such size or dye is baked hard
so that when the steam is again turned on some of the orifices remain closed, being
made up with size or dye, which the force of steam is unable to remove but by
the use of my improvements and by fixing to the steam inlet pipe 7 an air pipe 8
closed, or opened by valve 9 which is operated by the handle 10 which handle also
opens or closes the valve 11 on the steam inlet pipe 8 so that at the same time that
the supply of steam is shut off, the valve 9 on the air pipe 8 is opened and vice versa,
and the air filling the steam pipe when the supply of steam is stopped no vacumn
is formed and the size or dye does not penetrate into the steam pipe, only, at the
most filling the outer of the two conical holes 5. 6 and when the steam is again
turned on and the air supply cut off, any size or dye which may be in the nozzle 3.

page_text: is blown or forced out and the supply of steam is equal in all parts of the vat or
boiler 2.
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.
The use in combination with steam pipes, for purposes set forth, of the screw
nozzles having discharge orifices therein as described and illustrated by the annexed
drawing, the form of the orifice in such screw nozzles being varied according to circum-
stances and to the required discharge.
