IMPROVEMENTS IN APPARATUS FOR KIERS USED IN BLEACHING
Year: 1886

page_text: I, WILLIAM BRACEWELL of Brinscall, near Chorley, in the County of Lancastor,
Engineer, do hereby declare the nature of said invention for IMPROVEMENTS IN
APPARATUS FOR KIERS USED IN BLEACHING to be as follows:-
My invention has for its object the better carrying out of the distribution of
Liquor used in Kiers for bleaching, and relates to improvements in Apparatus as
aforesaid for which Letters Patent were granted to me A.D. 1878 No. 847 and my
Invention consists in placing Port holes, in the outer diameter of the flanges of
Liquor Well, the said Liquor well being referred to and marked C. C upon the
Drawings, and described in the Specification of the Patent, herein before referred
to. To carry the aforesaid into effect I insert between the flanges an Intermediate
plate, of the same diameter as the flanges of Liquor Well, having upon its upper
and lower surfaces, division strips of such a size and number, as to determine the
dimensions of the said port holes, being generally twelve in number, six of them
being upon the upper surface of the plate and six below, these port holes being
regulated in area by the pressure of steam acting upon them and the amount of
Liquor to be delivered.
The flow of Liquor passing through the port holes, in an horizantal position
comes in a more direct action, to the current of steam passing down, the central
steam pipe.
The object gained by this invention consists in the delivery from the Top of the
Fuse pipe of a flow of Boiling Liquor, without intermittance, being in all cases
delivered at the boiling point, thereby the goods under operation either in an open
or closed Kier, arrive at an higher temperature in a much shorter time, causing
oils and fatty substances, which have become impregnated in the goods during
manufacture, to become more solouble, thereby the process of scouring, cleansing, or
bleaching the goods, to be more effectually carried on.

I, WILLIAM BRACEWELL of Brinscall near Chorley in the County of Lancashire
Engineer do hereby declare the nature of said invention for "IMPROVEMENTS IN
APPARATUS FOR KIERS USED IN BLEACHING" and in what manner the same is.to
be performed, to be particularly described and ascertained in and by the following
statement, reference being had to the following accompanying drawings and to the
letters and figures marked thereon that is to say :--
My Invention has for its object the better carrying out of the distribution of
Liquor used in Kiers, and relates to improvements in Apparatus as aforesaid for
which letters patent were granted to me AD 1878 No 847 and my invention
consists in placing "Port holes" in the outer diameter of the flanges of Liquor well,
the same being attached to the lower end of Fuse pipe, as shown in section Fig. 2
and marked CC upon the drawings and described in the Specification of the
patent AD 1878 No 847 herein before referred to To carry the aforesaid into
effect I insert between the flanges of Liquor well an Intermediate plate, of the same
outward diameter as the flanges of Liquor well, having upon its upper and lower
surfaces, eight or more division strips, of such a size as to determine the dimensions
of the said port holes these port holes being regulated in area, by the pressure of
Steam, acting upon them from the inside, counterbalanced by the weight of liquor
passing through the said port holes from the outer side.
The flow of Liquor passing through the port holes in an horizantal position
comes in direct contact with the current of steam passing down the small central
steam pipe thereby establishing a regular distribution of Liquor from the top of
the pipe.
And in order that my invention may be fully understood and readily carried
into effect, I will proceed to describe the same, with reference to the accompanying
drawings, and to the figures and letters marked thereon.
Fig. 1 is a sectional elevation of an Open Bleaching Kier, for working upon
the low pressure system, including parts arranged to operate according to my
invention.
The vertical Fuse pipe F being shown in the centre of same, having liquor
well attached.
Figs. 2 and 4 are sectional and front elevation's of the Liquor well C being
upon an enlarged scale, the midfeather plate B, B being shown in its position upon
liquor well C.
Figs. 5 and 6 are detailed views of midfeather plate B, B' illustrative of the
means which I employ for establishing the required port holes D' in the outer
diameter of Liquor well C.
Similar letters refer to similar parts throughout the several views.
The vessel A Fig. 1 is filled with the goods required to be bleached or scoured,
boiling liquor is run upon the goods from the top side till the whole is completely
saturated and immersed in liquor.
The steam valve a Fig. 1 is then opened, & the steam passing down the small
central steam pipe b, impinges upon the bottom cone e Fig. 2 of Liquor well C, being

page_text: thereby diverted in an upward direction and by coming in direct contact with the
incoming liquor, through the port holes D¹, is forced to the top of Fuse pipe F, a
regular distribution of Liquor being showered upon the goods under operation.
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 I make
no general claim to distributing liquor upon goods undergoing the process of
bleaching, but what I claim is
1. The combination of "Port holes" in the Liquor well of Fuse pipo, so that a
flow of Liquor may enter the same above the current of steam.
2. The combination of Midfeather plate having 8 or any number of strips upon
its surface, whereby "Port holes" can be formed on the outer diameter of Liquor
well, as described and illustrated by the Drawings annexed, not binding myself to
any given dimensions.
