IMPROVEMENTS IN FURNACES FOR CARBONIZING WOOLLEN RAGS Communicated
[to him] from abroad by E Rosskam of Scherfede Westphalia Germany
Furnaces for purpose aforesaid according to this invention comprise a series of
steam-heating-pipes for heating the sieves which contain the woollen material to
be carbonized together with a carriage for running the sieves in and out of the
furnace. The fire-gases arising from two hearths of the furnace, are constructed
entirely of sand-stone and give direct heat to plates carrying vessels filled with
hydrochloric acid and pass thence to the chimney through coiled pipes securing
circulation of heat within the furnace. The principal heating of the sieves is, as
already mentioned effected by steain heating pipes, which extend length wise over
and under the sieves, three or more of which are placed one above the other.
whereby the material contained in the sieves is heated to a regular and constant
temperature of 75° R. Within the furnace the sieves are carried by rollers, but
when being withdrawn from or introduced into the furnace their exterior end is
supported by a carriage moved on rails to and fro before the stove and so
facilitating the bandling of the sieves. This carriage is provided at the different
levels of the sieves with supports on which the extremity of the sieve are laid
and carried.

WALTER BRIERLEY of Halifax in the County of York Patent Agent
"IMPROVEMENTS IN FURNACES FOR CARBONIZING WOOLLEN RAGS' communicated i
to me from abroad by E. Rosskam of Scherfede, Westphalia, Germany
Furnaces for purpose aforesaid according to this invention comprise a series of
steam heating pipes for heating tho sieves which contain the woollen material to
be carbonized together with a carriage for running the sieves in and out of the
furnace. The fire gases arising from two hearths of the furnace are constructed
entirely of sandstone and give direct heat to plates carrying vessels filled with
hydrochloric acid and pass thenco to the chimney through coiled pipes securing
circulation of beat within the furnace. The principal heating of the sieves is,
as already mentioned. effected by steam heating pipes which extend lengthwise
over and under the sieves, three or more of which are placed one above the other.
whereby the material contained in the sieves is heated to a regular and constant
temperature of 75° R. Within the furnace the sieves are carried by rollers. but
when being withdrawn from or introduced into the furnace their exterior end is
supported by a carriage moved on rails to and fro before the stove and so
facilitating the handling-of the-sieves. This carriage is provided at the different
levels of the sieves with supports on which the extremity of the sieves are laid
and carried.
Such being the nature and object of this my said invention I will now proceed
to describe the same in detail and in order that the invention may be fully
understood have hereunto annexed a sheet of drawings of which:
Fig. 1 is a longitudinal section of the furnace.
Fig. 2 a cross-section of the same.
Figs. 3 and 4 are horizontal sections.
Fig. 5 is a front view of the furnace.
The new feature of my carbonizing furnace is the arrangements of steam heating
pipes e for heating the sieves f which contain the woollen rags etc. the vegetablo
parts of which are in the well known manner to be carbonized, and the use
of a carriage h for placing the sieves f into and removing from the furnace.
The fire gases coming from the two hearths a a of my furnace constructed
entirely of sandstone give direct heat to the plates b carrying the vessels filled
with hydrochloric acid and pass thence to the chimney d through pipes c placod at
the bottom of the furnace and giving a more secondary heat. The principal
heating of the sieves f is, as already mentioned effected by the steam heating
pipes e which carried by the supports extend length wise over and under the
sieves. three or more of which are placed one above the other. In such way the
material contained in the sieves is heated to a regular and constant temperature
of 75° R. Within the furnace the sievos are carried by lateral rollers g but when
being withdrawn from or introduced into the furnace their exterior end is
supported by the carriage h moved on rails to and fro before the stove and so
facilitating the handling of the sieves f. This carriage his provided in the
different levels of the sieves with supports on which the extremity of the sieve
may be laid.
The wooden covers ii shut the apertures for introducing the sieves f. whilst the
wooden covers le give access to the plates b.

page_text: Having thus fully described the particulars of this my said invention I would
have it understood that what I claim is:
Firstly The disposition of the steam heating pipes e arranged over and under
the sieves fand in combination therewith as described and illustrated.
Secondly. The carriage h for carrying the ends of the sieves f and in
combination therewith when the same are withdrawn from or introduced into the
furnace.
In witness whereof I the said Walter Brierley have hereunto set my hand and
seal this twentyninth day of January in the year of our Lord one thousand eight
hundred and eighty four.
