and Morgan-Brown, Engineers and Patent Agents, of 38, South-
ampton Buildings, London, and 13, Rue Gaillon, Paris, for the In-
vention of "AN IMPROVED METHOD OF VENTILATING BLOWING MACHINES
USED IN AND IMPROVEMENTS IN THE MACHINERY FOR PREPARING FIBRES FOR
FELT HATS AND OTHER FELTED ARTICLES."-A communication from
abroad by Henry Mennig and Andrew Mennig, both of Cureghem,

PROVISIONAL SPECIFICATION left by the said William Morgan-Brown
at the Office of the Commissioners of Patents, with his Petition,
on the 14th October 1874.
I, WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-
3 Brown, Engineers and Patent Agents, of 38, Southampton Buildings,
London, and 13, Rue Gaillon, Paris, do hereby declare the nature of the
said Invention for "AN IMPROVED METHOD OF VENTILATING BLOWING MACHINES

page_text: USED IN AND IMPROVEMENTS IN THE MACHINERY FOR PREPARING FIBRES FOR FELT
HATS AND OTHER FELTED ARTICLES," to be as follows:-
This Invention consists in a novel method of utilizing the blowing
machines actually in use in the preparation of the fibres for the manu-
facture of felt hats and other similar articles.
Up to the present time these machines form two distinct and separate
parts, firstly, the ventilating apparatus; and secondly, the apparatus
furnished with teeth; the fibres leaving this first apparatus are received
in a series of chests or cases, from which it is necessary to remove and
transport them by hand into the second apparatus garnished with
teeth.
This Invention consists in uniting these two machines together by
means of a third apparatus disposed between them, and which I call a
distributing apparatus. This distributor is destined to deliver in a regular
and uniform manner in the machine following the fibre leaving the
first machine by means of a conduit through which said fibres are blown
into the distributing machine. In certain cases we place several of these
distributing machines one after the other, and we can equally suppress
the toothed machine and only make use of the ventilating machines.
Another part of our Invention consists in garnishing the ventilating
machine with teeth or pins in lieu of the pallets with which it is actually
furnished. By means of this novel disposition we are enabled to attach
an unlimited number of these machines together and thereby greatly
economise the fabrication of felt articles by suppressing an unnecessary
hand labour.
SPECIFICATION in pursuance of-the conditions of the Letters Patent,
filed by the said William Morgan-Brown in the Great Seal Patent
Office on the 13th April 1875.

Invention for "AN IMPROVED METHOD OF VENTILATING BLOWING MACHINES USED
IN AND IMPROVEMENTS IN THE MACHINERY FOR PREPARING FIBRES FOR FELT
HATS AND OTHER FELTED ARTICLES," a communication to me from abroad
by Henry Mennig] and Andrew Mennig, both of Cureghem, near
Brussels, Belgium, Mechanical Engineers, upon the condition (amongst
others) that I, the said William Morgan-Brown, my executors or ad-
ministrators, by an instrument in writing under my, or their, or one
of 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 I, the said William Morgan-Brown, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say:―
The machines employed until now in the treatment and preparation,
of the fibres used in the fabrication of felt hats and other similar articles
consist in two distinct and separate apparatus, 1°, the ventilating.
apparatus; and 2°, the apparatus formed of a machine consisting of
numerous bins or compartments, in each of which is mounted a cylinder
or drum garnished with teeth and serving to comb and clean the fibre ;
and the said fibres on leaving the first apparatus have to be collected in
a series of receptacles from which they are removed by hand in order to
be deposited in the second apparatus.
Now this Invention relates in the first place to the construction of a
thin onnenntun
;

page_text: placed between the two above-mentioned machines receives the fibres
destined for the manufacture of hats or other similar felted fabrics at
their exit from the first one in order to conduct them regularly and
without intermission to the second or toothed machine, and in the
second place in divers modifications or improvements in the construction a
of the machines actually in use.

page_text: endless belt or aproṇ n, and from there through a pair of rollers o, o,
from which they come out in the shape of a uniform and regular sheet,
falling on an endless belt which conducts it into the ordinary toothed
machine.
It will be evident that the length of the conduit p will depend on the
space afforded by the workroom, it should not however exceed from
thirty to thirty-five feet.
Another part of the Invention consists in a modification in the con-
struction of the ventilator, according to which the ordinary pallets
composing the latter are replaced by a certain number of cross pieces 8, 8,
Figure 2, on which are attached strips of wood t, t, having the full width
of the machine and covered on their entire surface by steel teeth or
pins u, u, placed very closely together, the counterpart being equally
furnished with similar teeth in like manner. The advantage of this
novel disposition consists in the fact that the fibres undergo at once a
first combing and are thus more easily freed from the coarse fibres and
other impurities which before necessitated four or five separate combings
before attaining the degree of finish which this Invention obtains in a
single operation.
Another part of the Invention consists in a modification of the con-
struction of the cylinders of the toothed apparatus. The cylinders are
garnished as usual with about 2500 little pins, but to these is given a
slight rounded extremity, and thus is obtained a much better result in
facilitating considerably their contact with the fibres as they leave the
rollers, a fixed counterpart x, Figure 3, being furnished with similar
teeth or pins. Figure 3 represents this disposition, the fibres leaving
the rollers o, o, of the distributing machine are received on the endless
belt passing over the rollers w, w, and which travelling in the direction
indicated by the arrow conducts them between the rollers z, z, from
which they are carried away by the effect of the rotation of the
cylinders a¹ to be deposited after having been well combed on a second
endless belt which carries them to the next cylinder, while the coarse
fibres and other impurities fall in the space existing between the cylinder
and the roller w.
Another part of this Invention consists in being able to impart
pressure to the cylinders instead of allowing them to turn freely as has
been until now the case; Figure 4 represents this modification, in

page_text: which ¹ is a lever bearing on the brass of the upper cylinder z, and
whose pressure can be easily regulated by shifting more or less on said
lever the rod c', at the extremity of which is suspended a weight d¹.
By the novel disposition of these machines there can be fixed up
numerous apparatus all united and working together, and thus economise
the cost of hand labour.
Having now described and particularly set forth the nature of the said
Invention, and the manner of carrying the same into effect, I would have
it understood that what I claim is,—
Firstly. The distributing apparatus disposed and working in the
manner described.
Secondly. The modification in the construction of the ventilator, sub-
stantially as described.
Thirdly. The modification in the construction of the teeth in the
toothed apparatus.
And, Fourthly. The pressure applied to the cylinders of same, sub-
stantially as described.
In witness whereof, I, the said William Morgan-Brown, have here-
unto set my hand and seal, this Thirteenth day of April, in
the year of our Lord One thousand eight hundred and seventy- :
five.
