IMPROVEMENTS IN THE MANU- FACTURE OF WINDOW BLINDS
Year: 1864

page_text: LETTERS PATENT to Adolph Bösch, of No. 30, Hatton Garden, in the
City of London, for the Invention of "IMPROVEMENTS IN THE MANU-
FACTURE OF WINDOW BLINDS."-A communication from abroad by Max
Baumstark, residing at No. 2, Cavo Vettabbia. Milan
Sealed the 3rd January 1865, and dated the 12th July 1864.
PROVISIONAL SPECIFICATION left by the said Adolph Bösch at the
Office of the Commissioners of Patents, with his Petition, on the 12th
July 1864.
I, ADOLPH BÖSCH, of No. 30, Hatton Garden, in the City of London, do
hereby declare the nature of the Invention for "IMPROVEMENTS IN THE MANU-
FACTURE OF WINDOW BLINDS," to be as follows:-
This Invention has for its object improvements in the manufacture of
window blinds. For these purposes very slight thin rods of wood of a cylin-
drical or other transverse section are used, which are woven together as weft
by means of warp threads at intervals, leaving the intermediate parts without
warps. In weaving the fabric for these blinds, sheds are, by preference,
opened in the warp by what is technically known as cross weaving; the slight
rods of wood are introduced and tied or bound, and held tightly in between
the warps. The distances apart at which the warps are used may be varied,
and the number of warps at each place may also be varied according to the
effect desired to be produced. Ordinarily, however, the sets of warps are
Price &d

page_text: equally spaced, say, from an inch to an inch and a half apart, and each set
cousists of four warps of a suitably strong thread of flax or other material.
The four, constituting a set, are divided, and are worked two warps below
and two warps above; and the two pairs are alternately raised and depressed,
and the slight rods of wood are passed into the sheds as they are successively
opened.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Adolph Bösch in the Great Seal Patent Office on the
12th January 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ADOLPH
Böscн, of No. 30, Hatton Garden, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of July, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Adolph Bösch, Her special licence that I, the said Adolph Bösch,
my executors, administrators, and assigns, or such others as I, the said
Adolph Bösch, my 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
THE MANUFACTURE OF WINDOW BLINDS," a communication to me from abroad
by Max Baumstark, a person resident at No. 2, Cavo Vettabbia, Milan,
upon the condition (amongst others) that. I, the said Adolph Bösch, my
executors or administrators, 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 per-
formed, 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 Adolph Bösch, 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 :-
This Invention has for its object improvements in the manufacture of

page_text: window blinds. For these purposes very slight thin rods of wood of a cylin-
drical or other transverse section are used, which are woven together as weft
by means of warp threads at intervals, leaving the intermediate parts without
warps.
In weaving the fabric for these blinds sheds are, by preference,
opened in the warp by what is technically known as cross weaving; the
slight rods of wood are introduced and tied or bouned, and held tightly in
between the warps. The distances apart at which the warps are used may
be varied, and the number of warps at each place may also be varied
according to the effect desired to be produced. Ordinarily, however, the sets
of warps are equally spaced, say, from an inch to an inch and a half apart,
and each set consists of four warps of a suitably strong thread of flax or other
material. The four, constituting a set, are divided, and are worke dtwo
warps below and two warps above; and the two pairs are alternately raised
and depressed, and the slight rods of wood are passed into the sheds as they
are successively opened.
Having thus stated the nature of the said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure shews the principal parts of a perspective view of a loom used in
manufacturing window blinds according to the Invention; Figure 2 shews
one of the spindles separately, by which the warps are caused alternately to
rise and fall, and to twist with each between the succeeding slight thin rods
of wood which are introduced as weft in the sheds opened in the warp.
The arrangement of the machinery used for weaving these blinds may be
varied, but that shewn by the Drawings is what is preferred, it consists of a
series of hollow spindles a, a, one of which is shewn separately at Figure 3,
and they are to have a reciprocating rotatory motion communicated to thom
in any convenient manner. In the Drawings there is a toothed pinion b on
each spindle, which may take into a toothed rack, to which a to-and-fro
motion is communicated in any convenient manner. It is preferred that
there should be four strong yarns or fine cords to each spindle, and that two
of them should be threaded through the eye a' in each horn of the spindle.
The spindles turn in suitable bearings, and the warps are supplied from a
beam at the back of the loom. As a shed is opened a wood rod c is intro-
duced by hand, as is shewn in Figure 1. The yarns or cords of each spindle
pass through a space in a reed d suspended in front of the spindles. The
work is wound up on to a beam e after it has passed over a breast beam or
bar f

page_text: In some cases the spindles are made to rotate in the same direction, the
rods of wood being introduced when the shed is opened.
Having thus described the nature of the Invention, and the manner of
performing the same, I would have it understood that what I claim is the
manufacture of window blinds herein described.
In witness whereof, I, the said Adolph Bösch, have hereunto set my
hand and seal, this Eleventh day of January, in the year of our
Lord One thousand eight hundred and sixty-five.
ADOLPH BÖSCH. (L.S.)
