IMPROVEMENTS IN BOLTERS
Year: 1850

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Joseph
FOOT, of Spital Square, 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 Twenty-seventh day of
June (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 Joseph Foot, my exors, adññors, and assigns, Her especial license, full
power, sole privilege and authority, that I, the said Joseph Foot, my exors,
adiñors, and assigns, or such others as I, the said Joseph Foot, my exors,
admors, 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, my Invention of "IMPROVEMENTS IN
BOLTERS;" in which said Letters Patent is contained a proviso that I, the
said Joseph Foot, shall cause a particular description of the nature of my
said Invention, and in what manner the same is to be performed, by an
instrument in writing under my hand and seal, to be inrolled in Her

page_text: said 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.
NOW KNOW YE, that in compliance with "the said proviso, I, the
said Joseph Foot, do hereby declare that the nature of my Invention,
and the manner in which the same is to be performed, are fully described
and ascertained in and by the following statement thereof, that is to
say:-
My Invention consists of the employment of silk in the manufacture of
bolters. And in order that my Invention may be most fully understood and
readily carried into effect, I will proceed to describe the means pursued by mc.
I would, however, first remark, that heretofore in constructing bolters wool
has been employed, but it is well known that there are numerous projecting
ends of fibres which stand off from the surfaces of such yarn, which interfere
with the holes or meshes of the open weavings, and I have found that by
employing silk that a great improvement is obtained, and that a larger product
of flour results. In using silk I employ Italian silk by preference, and thrown
in the manner of organzine, but with more twist, in order to make the same
as wirey as may be, and I weave the same into a tubular form, as is well
understood. And in order that the tubular fabrics of silk thus made may be
larger at one end than at the other, as is generally though not invariably
preferred for bolters, I cause the made work to be moistened with water by a
sponge applied from time to time between the reed and the breast roll, and
in winding up the fabric as it is woven the workman adjusts the work to the
requisite width as he proceeds, and which when wound on the breast roll and
dry, it will retain. These fabrics are then completed by having the head
and tail leathers attached as when using wool, and the same are to be be used
as heretofore, and as is well understood. I would state that although I usually
employ silk for the warp and weft, I do not confine myself thereto, as yarn of
wool may be used with silk, particularly for the weft.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that what I claim is, tho
employment of silk in the manufacture of bolters.
In witness whereof, I, the said Joseph Foot, have hereunto set my hand
and seal, this Twenty-sixth day of December, in the year of our Lord
One thousand cight hundred and fifty.
JOSEPH (L.S.) FOOT.
