We, CHARLES EDWARD MIDDLETON, FRANCIS PHILIP MIDDLETON, and
ARTHUR THOMAS MIDDLETON, all Manufacturers, and of Adlington, in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
It consists in certain improvements in what is known as Obermier's apparatus,
for dyeing cops under hydraulic pressure, and relates more particularly to the
boxes or cases employed for holding the cops during the process.
The cases as at present used, are open at the ends as well as the sides and are
difficult to pack with cops in such a manner as to insure a perfect process of dyeing,
a great quantity of waste material having to be used to fill the ends and interstices
between the cops, and between the case and the compartment it is in, and the
pressure necessary in attempting to obtain a perfect fit of the case &c. in the vat,
seriously damages the cops.
To overcome the above difficulties we form the cases with closed ends leaving
only two sides open.
Upon the edges of the open sides, we form or fit frames or surfaces of suitable
metal, planed or otherwise formed to a true surface, which fit or slide into suitable
frames or slides in the vat, so as to obtain a perfect fit or joint between the open
sides of the case and the vat, this being further facilitated by means of a thin
strip of indiarubber, or other suitable material, attached to one, or both, of the
surfaces in contact.
The cops are placed sideways into the case, very little waste packing being
required, and the two perforated side plates, are slided into position in suitable
grooves in the flanges before mentioned."
By this arrangement the hydraulic pressure is utilized to tighten the joint of the
outside of the case against the vat, it being impossible for any liquor to pass out.
of the vat excepting through the cops.
I also furnish the lid of the compartment in which the case is placed, with
similar planed, (or other) contact surfaces, and india rubber, (or other) joint, so as
to insure a tight joint, without loose or waste packing.

COMPIDID DI MUITIVATION.
Improvements in Dyeing Apparatus.
We, CHARLES EDWARD MIDDLETON, FRANCIS PHILIP MIDDLETON, and
ARTHUR THOMAS MIDDLETON, all Manufacturers, and of Adlington, in the
County of Lancaster, do hereby declare the nature of this invention and in wha
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
It consists in certain improvements in what is known as Obermier's apparatus,

page_text: used for dyeing cops under hydraulic pressure, and relates more particularly to
the boxes or cases employed for holding the cops during the process.
The cases as at present used are open at the euds as well as the sides, and are
difficult to pack with cops in such a manner as to insure a perfect process of
dyeing, a great quantity of waste material having to be used to fill the ends of
the cases and the interstices between the cops, and also between the case and the
compartment it is in.
In addition to this, the pressure necessary in attempting to obtain a perfect fit
of the cases &c. in the vat, seriously damages the cops.
To overcome these difficulties is the object o. our invention.
This we accomplish as follows:-
:―
We form the cop cases with closed ends and sides (which may be perforated)
leaving only two sides open, and upon the edges of the open sides, we form or fit
frames, or surfaces of suitable metal planed or otherwise formed to a true surface,
which fit or slide into suitable frames or slides in the vat or chest, so as to obtain
a perfect fit or joint, between the open sides of the case and the vat, this being
further facilitated by means of a thin strip of indiarubber or other suitable material
attached to one or both of the surfaces in contact.
The cops are placed sideways into the case, very little waste packing being
required and the two moveable perforated plates at the sides are slid into position
in suitable grooves in the Hanges or surfaces before mentioned.
We also furnish the compartment of the vat or chest, in which the cop case is
placed, with a suitable metal lid, with similar planed (or other) contact surfaces,
and indiarubber (or other) joint, so as to insure a tight joint without any loose or
waste packing.
By this arrangement the hydraulic pressure is utilized to tighten the joint of
the outside of the case against the outerside of the vat or chest, making it
impossible for any liquor to pass out of the vat or chest except through the cop
case and cops.
Referring to the drawings sent herewith :-
Figs. 1, 2 and 3 are respectively, a front, side and top view of our improved
cop case.
Figs. 4 and 5 are respectively a cross section and plan of the vat or chest with
our improved fittings.
The cop case a is fitted with flanges or surfaces planed to a true surface as
before mentioned and is completely closed excepting on two sides c c which are
fitted with perforated and moveable plates d, which slide in grooves b4 in flanges b,
one of these perforated plates d is shown only partly closed in Figs. 1 and 2.
It is reversable and is fitted with a suitable handle e at each end for convenient
handling.
The cop case a is placed upright in compartment f of vat or chest g, being
guided into position by guide or slide h which is sometimes furnished with a suit-
able spring 2 to press the faces or flanges b of the cop case a firmly against
the corresponding faces i on the outlet side of the compartment f.
A suitable metal lid k is then fitted upon the top of compartment f fitting upon
faces or flanges and screwed up tight by means of screw m and handle n.
All other outlets being now tightly closed, the dye liquor is pumped in by inlet o
and passes out through cop case a (pressing it firmly against the side of the com-
partment, and so stopping all leakage) in the direction shown by arrows on
drawing.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1st. The improved cop case, substantially as described and shown herein before
and in the accompanying drawings, for the purpose set forth.
2nd. In a dyeing vat, the improved metal lid k and guide or slide h, either with

page_text: or without spring h2, substantially as described and shown herein before and
in the accompanying drawings.
3rd. The combined apparatus, substantially as described and shown, herein before
and in the accompanying drawings for the purpose set forth.
