We, WILLIAM BAXTER and DENTON WARING, of Raglan's Mill,
Bradford, in the County of York, Wool Extractors, and JOSEPH SWITHIN
WOOLLER, of Bradford, aforesaid, Dyer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN APPARATUS FOR DRYING TEXTILB

page_text: FABRICS AND FIBROUS SUBSTANCES, APPLICABLE ALSO FOR HEATING OR COOLING AND
EVAPORATING LIQUIDS," to be as follows:-
This Invention relates chiefly to means or apparatus for drying the
rags of fabrics as required to be done in the process of extracting the
wool from them or for drying wool or other fibrous substances, but the
said apparatus is also applicable for heating or cooling or evaporating
water or other liquids. The apparatus consists of a series of metal pipes
connected together in sets, each set forming a grated platform or shelf of
pipes, and so arranged that steam, water, or air may circulate therein.
These sets or shelves of pipes are arranged in tiers one over another, and
may either be fixed in proper positions on suitable framework or they
may be capable of being raised and lowered to place them nearer to or
further from each other by means of racks and pinions, screws and nuts,
or other suitable means.
For drying purposes the whole series of pipes may be enclosed in a
casing or chamber and air forced or drawn through, and sheets of wire
netting may be employed to place the rags or fibrous substance upon,
which are then placed on the pipes.
For heating or cooling and evaporating liquids the apparatus must
be constructed so as to be placed in the vessel containing the said liquids,
and steam, hot or cold water, or air passed through the pipes as the case
requires.
SPECIFICATION in pursuance of the conditions of the Letters Patent,

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
BAXTER and DENTON WARING, of Raglan's Mill, Bradford, in the County
of York, Wool Extractors, and JOSEPH SWITHIN WOOLLER, of Bradford,
aforesaid, Dyer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of June, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,

page_text: give and grant unto us, the said William Baxter, Denton Waring,
and Joseph Swithin Wooller, Her special licence that we, the said
William Baxter, Denton Waring, and Joseph Swithin Wooller, our
executors, administrators, and assigns, or such others as we, the said
William Baxter, Denton Waring, and Joseph Swithin Wooller, our
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN APPARATUS FOR DRYING TEXTILE FABRICS AND FIBROUS SUBSTANCES, APPLICABLE
ALSO FOR HEATING OR COOLING AND EVAPORATING LIQUIDS," upon the condition
(amongst others) that we, the said William Baxter, Denton Waring,
and Joseph Swithin Wooller, our executors or administrators, by an in-
strument in writing under our, or their, or one of our or their hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said William Baxter, Denton Waring,
and Joseph Swithin Wooller, do hereby declare the nature of our
said Invention, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following state-
ment and accompanying Sheet of Drawings (that is to say) :-
This Invention relates chiefly to means or apparatus for drying the
rags of fabrics as required to be done in the process of extracting the
wool from them or for drying wool or other fibrous substances, but the
said apparatus is also applicable for heating or cooling and evaporating
water or other liquids. The apparatus consist of a series of metal pipes
connected together in sets, each set forming a grated platform or shelf
of pipes, and so arranged that steam, water, or air may circulate therein.
These sets or shelves of pipes are arranged in teirs one over another, and
may either be fixed in proper positions on suitable framework or they
may be capable of being raised and lowered to place them nearer to or
further from each other by means of racks and pinions, screw, and nuts,
or other suitable means.

page_text: For drying purposes the whole series of pipes may be enclosed in a
casing or chamber and air forced or drawn through, and sheets of wire
netting may be employed to place the rags or fibrous substance upon,
which are then placed on the pipes.
For heating or cooling and evaporating liquids the apparatus must be
constructed so as to be placed in the vessel containing the said liquids,
and steam, hot or cold water, or air passed through the pipes as the case
requires.
In order that this Invention may be clearly understood we herein give
reference to an accompanying Sheet of Drawings illustrating the same.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 represents a side elevation of the said apparatus, and Fig. 2 a
plan of the same.
A are the series of pipes, which in this case are connected together
in sets of ten by boxes B, each set thus forming a shelf or platform
composed of pipes, and the several shelves or platforms are arranged one
above another, as marked with the Figs. or Numbers 1, 2, 3, 4, 5, 6. Each
shelf is supported by a shaft C, on which are two pinions D gearing
into racks E fixed on upright pillars F, which also form steam pipes or
pipes to convey steam to the series of pipes, each shelf being connected
by conducting pipes G to two of the said upright pillars, the one for
inlet of steam (or other heating or cooling media), and the other for outlet
of steam and condensed water or other media used. On each end of the
shaft C is fixed a worm wheel H which gears into worms I fixed on
the horizontal shafts J, by the turning of which the shelves may be
raised or lowered, each shelf being separately geared to one of the said
shafts, so that any one of the said shelves may be moved independantly
of the others.
In the using of this apparatus for drying rags, fabrics, or fibrous
substances, we may either lower the shelf No. 1 or raise the shelf
No. 2, so as to make more opening betwixt them for the introduction of
the rags, and then lower the shelf No. 2 into close contact with the said
rags. The opening betwixt No. 2 and No. 3 may then be charged, and
the later shelf lowered thereon, and so on until all the spaces betwixt
the shelves are charged. Steam is then turned into the pipes, which as it

page_text: circulates through them produces heated and therefore drying surfaces
of the said pipes, which, as is well understood, will dry the rags.
It will be observed that this apparatus may be either placed in a room
which can be kept close during the drying process so as to economise
the heat, such room being provided with suitable means of ventilation
for the escape of the vapours or moisture arising from the rags or
fabrics or fibrous substances under operation; or this apparatus may be
enclosed in a casing or chamber constructed of any suitable material for
the purpose, being provided with doors and openings to admit of the
charging and discharging of the rags or fabrics, and air may be forced or
drawn through the room or chamber to facilitate the process of drying.
Also it will be observed that instead of placing or spreading the rags
upon the pipes as above explained sheets of wire netting may be
employed to spread the rags upon, and which may then be placed upon
the shelves of pipes, and these shelves of pipes may either be arranged
on constructed to move up and down as shewn, or may be stationary if
desirable.
When this apparatus is to be used for heating or cooling liquids or for
evaporating liquids it must be constructed of suitable dimensions to be
placed in the vessel or cistern containing the liquids in which it will be
immersed. Either steam, hot water, or hot air may then be passed
through the pipes for heating or evaporating the said liquids, or if to
be used for cooling purposes the cold water or cold air may be
passed through the said pipes. We prefer the method of connecting the
pipes by turning the ends taper to fit holes bored in the boxes and passing
bolts through to hold them, but other methods may be adopted of
connecting them.
Having thus described the nature of our said Invention, and shewn
by the accompanying Sheet of Drawings how the same is to be or may
be performed or carried into practical operation, we would have it
understood that we do not confine ourselves to the precise details of
construction or arrangement of the parts of the apparatus which we have
shewn and described, as various modifications may be made therein;
but what we claim as of our Invention is, the construction and use of
apparatus for the purposes set forth comprising a series of metal pipes
connected together in sets forming grated platforms of shelves arranged
in tiers one above another either fixed or moveable, and so that steam,

page_text: water, or air may circulate therein and may be enclosed (or not) in a
room or chamber for air to be forced or drawn through them when
used for drying rags, fabrics, or fibrous substances, or immersed in the
liquid when used for heating, cooling, and evaporating the same.
In witness whereof, we, the said William Baxter and Joseph
Swithin Wooller, for and on behalf of ourselves and the said
Denton Waring, have hereunto set our hands and seals, this
Twenty-sixth day of December, in the year of our Lord One
thousand eight hundred and sixty-eight.
Signed, scaled, and delivered
by the within-named William
Baxter and Joseph Swithin
Wooller, in the presence of
