Year: 1853

page_text: LETTERS PATENT to Richard Dart, of the firm of Dart and Son, of
12, Bedford Street, Covent Garden, in the County of Middlesex,
Carriage Lace Manufacturer, and Edward Silverwood, Weaver,
in the employ of the said firm, at the said place, for the Invention
of "THE ADAPTATION OF LOOM MACHINERY TO THE PURPOSES OF
EMBROIDERY FOR BADGES WORN BY THE POLICE, RAILWAY OFFICIALS,
AND OTHER OFFICERS, AND WHICH REQUIRE A SUCCESSION OF FIGURES."
PROVISIONAL SPECIFICATION left by the said Richard Dart and
Edward Silverwood at the Office of the Commissioners of Patents,
.with their Petition, on the 19th July 1858.
We, RICHARD DART (of the firm of Dart & Son) and EDWARD SIL-
VERWOOD, do hereby declare the nature of the said Invention for "THE
ADAPTATION OF LOOM MACHINERY TO THE PURPOSES OF EMBROIDERY FOR
BADGES WORN BY THE POLICE, RAILWAY OFFICIALS, AND OTHER OFFICERS, AND
WHICH REQUIRE A SUCCESSION OF FIGURES," to be as follows:-

page_text: This Invention consists in the adaptation of the "leases" and "tyres"
of the loom to the production of a series of numbers to any extent
without alteration to the original "setting up."
This is effected by means of mounting the loom for the nine digits
and the 0, so that any number can be taken up and woven into the
fabric when required, thereby removing the great difficulty which has
hitherto always presented itself in weaving badges for servants or
officials requiring to be numbered. A piece of the garment of the de-
sired size and form is thus woven, and may then be attached to the
same, forming part of it.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Richard Dart and Edward Silverwood in the
Great Seal Patent Office, on the 19th January 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc,
RICHARD DART, of the firm of Dart and Son, of 12, Bedford Street,
Covent Garden, in the County of Middlesex, Carriage Lace Manufac
turer, and EDWARD SILVERWOOD, Weaver, in the employ of the said firm,
at the said place, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of July, in the year of
our Lord One thousand eight hundred and fifty-three, in the seventeenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Richard Dart and Edward Silverwood, Her
special licence that we, the said Richard Dart and Edward Silverwood,
our executors, administrators, and assigns, or such others as we, the said
Richard Dart and Edward Silverwood, our exccutors, 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 "THE ADAPTATION OF LOOM MACHINERY
TO THE PURPOSES OF EMBROIDERY FOR BADGES WORN BY THE POLICE, RAILWAY

page_text: OFFICIALS, AND OTHER OFFICERS, AND WHICH REQUIRE A SUCCESSION OF
FIGURES," upon the condition (amongst others) that we, the said
Richard Dart and Edward Silverwood, by an instrument in writing
under our hands and seals, or under the hand and seal of one of us,
should particularly describe and ascertain the nature of the said Inven-
tion, 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 inniediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Richard Dart and Edward
Silverwood, do hereby declare the nature of our said Invention, and
in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
The nature of this Juvention consists in the use of the loom for the
production of a series of letters and numbers to any extent without
alteration to the original setting up. This we effect by means of
mounting the looms for the nine digits and the cypher (0), so that any
number can be taken and woven into the fabric where required,
thereby removing the great difficulty which has hitherto always pre-
sented itself in weaving badges, viz., the remounting of the loom.
In the case of the adaptation of this Invention to a garment, a piece
of the desired size and form may be thus woven, and then be attached
to the same, forming part of it.
And for the better exemplification of the nature of our said Inven-
tion, and particularly as to what manner the same is to be performed,
we now proceed particularly to describe the adaptation of loom ma-
chinery which we prefer in order to accomplish the objects above
stated.
The loom like those ordinarily used for weaving coach lace is con-
structed on what is termed (since the invention of the jacquard) the old
lease principle, with the following modifications, namely:-The leases
are wider, the width being so far increased as to allow of an extra
number of tyres being used, as it is desirable to have one for each letter
of the alphabet and for each numeral.
The tyre racks are duplicate, and the one nearest the loom contains
twenty-seven tumblers, being one for each. letter in the alphabet, and

page_text: the other contains ten tumblers, being one for each numeral; and if
more than one set of letters or set of numerals be employed, then-a cor
responding number of tyres and tumblers must be employed likewise;"
Sundry "comber boards "(boards perforated with holes) are placed
in various parts of the loom to keep the thirty-seven cords of the thirty-
seven tyres (a very unusual number) from tangling the one in the other.
The cross piece is constructed with two rows of notches to-hold dowi
the tyres, one row for the letters and the other for the figures, and the
glass rolls are crossed at right angles with short rolls, and the cords
attached to the story leases are brought down outside the cross rolls.
PECULIARITIES in the manner of using this Loom.
In using this loom for the purposes set forth no regard is had in the
Drawing or Draught from which the loom is "mounted" to making
the tyres of equal length.
The tyres are not taken up consecutively as they appear on the 1
Draught, and as they are arranged in the loom, each letter and each
figure forming a separate and independent tyre is drawn as required.
In weaving two rows of letters or figures in the same badge two
tyres are sometimes worked simultaneously. When two sets of binders
are worked together one set becomes the choke," whilst the other s
acts as binder, and is changed by changing the right foot treadles.
The above is a description of the first loom we have prepared com-
plete for working our Patent. We shall prepare other looms similarly,
but not exactly the same in all its details, as for example:-One for
the Panopticon Institution, in which some of the parts are duplicate,
for the purpose o weaving two rows of letters and numerals in the
sane piece of fabric
Having now described the nature of the said Invention, and in what
manner the same is to be performed, we declare that we do not claim
the exact and particular construction of the loom as the main and 3
essential part of our Patent, but the right of so adapting a loom to
avoid the necessity of remounting for any changes required in letters
nd numerals, which we may describe as follows:-

page_text: 1. We make every letter and numeral work separate and inde-
pendent of each other.
2. We work every letter and numeral in whatever order we require
them, and not of necessity in the order in which they follow each other
in the loom.
8. We mount the loom at once with the entire alphabet and the
ten numerals, although we are able to accomplish the entire object
without mounting for all the letters, as part of some can be made to
form parts of others, as, for example, the upright part of the letter .P,
will produce the letter I, and the round of the C, being repeated back-
wards will form the letter O.
These arrangements, as applied by us to weaving letters and
numerals, we believe to be entirely novel, and to constitute the main
and essential features of our claini.
By this means we are enabled to employ the machinery of a loom
for the production (without a second "mounting ") of badges numbered
from one upwards to any extent. We sometimes work two or more
tyres simultaneously; this is when we adopt the loom, as we have done
that in the Panoptican Institution, to weave more than one row of
letters or numerals in the same fabric.
In witness whereof, 1, the said Richard Dart, on behalf of
myself, the said Richard Dart and Edward Silverwood, have
hereunto set my hand and seal, this Eighteenth day of Ja-
nuary, in the
year of our Lord One thousand eight hundred and
fifty-four.
Signed and sealed in my presence,
F. W. CAMPIN,
Patent Agent, Strand.
