IMPROVEMENTS IN PREVENTING THE EXTERNAL AIR AND DUST AND NOISE FROM ENTERING APARTMENTS
Year: 1850

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RODOLPHÉ
HELBRONNER, of Regent Street, in the County of Middlesex, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of
Great Britain and Ireland, bearing date at Westminster, the Thirty-first
day of July, One thousand eight hundred and fifty, in the fourteenth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Rodolphe Helbronner, my exors, adiňors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said Rodolphe
Helbronner, my exors, admors, and assigns, or such others as I, the said
Rodolphe Helbronner, my exors, adiñors, or assigns, should at any time agree
with, and no others, from time to time and at all times during the term of
years therein expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, the
Invention of "IMPROVEMENTS IN PREVENTING THE EXTERNAL AIR AND DUST AND
NOISE FROM ENTERING APARTMENTS," communicated to me from abroad; in
which said Letters Patent is contained a proviso that I, the said Rodolphe
Helbronner, shall cause a particular description of the nature of the said
Invention, and in what manner the same is to be performed, by an instru-
ment in writing under my hand and seal, to be inrolled in Her Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by
the same, reference being thereunto had, will more fully and at large appear.

page_text: Figure 1 shows a front view, Figure 2 is a plau, and Figures 3 and 4 show
two end views of a table and apparatus for making rolls of fibrous material
applicable to the purposes mentioned. Figure 5 shows part of a left-hand end
view when at work; Figure 6 shows a transverse section, with the parts in
position when introducing the sheet of fibres out of which a roll is to be made;
and Figure 7 shews a section through the line (1, 1), with the flap open, but
it is also shewn by dotted lines in the position it would assume when com-
mencing to work. Figure 8 shows parts of two rolls complete; the diameter,
however, may be varied according to the requirement.
Figures 5, 6, 7, and 8, shew the parts full size. a, a, is the framing; ba
bench or upper surface on which the work is performed; b' is a ridge or
raised part over which the sheet of fibre is placed; 63 is a flap which is folded
down when making a roll. The bench at the right-hand end, and also the
flap, is hollowed out, as shewn at *, *, in order that the wires may turn
freely. c is a spindle which turns in bearings d, d. The spindle c receives
motion from the pulley e by means of a band f acting on the pulley f', fixed
on the spindle c. The spindle c carries two steel wires g and h; the wire g is
in the centre, and is readily removed therefrom. The wire h is fixed to the
spindle c at a distance from the centre. The machine is used in the following
manner: A sheet of fibres of cotton or other fibres is placed on the bench as
shewn at i, i, in such manner that one of its edges comes between the two
wires, as shewn in the Drawing. The hinged flap of the bench is then closed
on to the wires, when, on rotatory motion being given to the spindle c, the
sheet of fibres will be wound around and on the wires, and thus will be formed
a roll, which is to be taken off by first drawing out the wire g, and then the

page_text: roll may readily be removed off the wire h. The roll thus far made is next to
be coated with any suitable cement to cause the fibres on the surface to
adhere, and thus to obtain a smooth surface. If it be desired to be made
waterproof, I prefer to employ a solution of india rubber or of gutta percha,
which is spread or applied by a brush to the outer surface of the roll of fibre,
and the same is then hung up to dry, which I do by means of a string, as
shewn at j. When the first coat of the cement is dry I apply a second, and
by these means are produced rolls of fibres coated on their outer surfaces with
cement, according to the Invention. The sheets of fibres for carrying out the
Invention may be made in like manner to like sheets when for making
wadding, or they may be made in any convenient manner, the same forming
no part of my Invention. Such rolls of fibre are applied to cover or fill the
spaces between doors, windows, and the frames thereof, and other narrow
openings or spaces through which air, noise, and dirt pass, such rolls being
fixed by glue or otherwise.
Having thus described the nature of the Invention, and the manner in
which the same is to be performed, I would have it understood that what I
claim is, the means of making rolls suitable for and applying them to prevent
external air, dust, and noise entering apartments.
In witness whereof, I, the said Rodolphe Helbronner, have hereunto
set my hand and seal, this Thirty-first of January, in the year of
our Lord One thousand eight hundred and fifty-one.
RODOLPHE (L.S.) HELBRONNER.
AND BE IT REMEMBERED, that on the Thirty-first day of January,

fication aforesaid, and all and every thing therein contained and specified, in
form above written. And also the Specification aforesaid was stamped
according to the tenor of the Statute made for that purpose.
Enrolled the Thirty-first day of January, in the year of our Lord One
