IMPROVEMENTS IN THE MANUFACTURE OF METALLIC LATTICE OR TRELLISWORK
Year: 1859

page_text: LETTERS PATENT to George Baker, of Birmingham, in the County of
Warwick, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF
METALLIC LATTICE OR TRELLISWORK."-A communication from abroad
by Owen Carraway, late of New York.
Sealed the 7th October 1859, and dated the 29th June 1859.
PROVISIONAL SPECIFICATION left by the said George Baker at the
Office of the Commissioners of Patents, with his Petition, on the
29th June 1859.
I, GEORGE BAKER, of Birmingham, in the County of Warwick, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN THE MANUFACTURE
OF METALLIC LATTICE OR TRELLISWORK," to be as follows:-
This Invention has for its object improvements in the manufacture of
metallic lattice or trelliswork. Heretofore in the manufacture of such
descriptions of work it has been usual to employ straight wires or rods, which
at their intersections are tied with thin wire, or else the wires themselves are
twisted or interlaced at their intersections. Now, this Invention consists in
causing the wires or rods, whether cylindrical or of other section, to be first cor-
rugated, and then to be combined by such corrugated wire or rod being passed
alternately under and over the neighbouring corrugated wires or rods, by
which means, at the intersections of the several wires or rods, two hollows or
bends will come together in each case, by which they will without being tied

page_text: by small wires, and without being twisted, be prevented sliding or moving out
of position at the angles or intersections. In preparing the wires or rods for
these purposes, it is preferred to employ a corrugating machine, consisting of
two parallel axes driven by any suitable power, each having a similar toothed
wheel thereon, the teeth of which gear together; such teeth being formed
with a rounding surface corresponding with the bends or corrugations desired
to be given to the wires or rods.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Baker in the Great Seal Patent Office on the
29th December 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
BAKER, of Birmingham, in the County of Warwick, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of June, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said George Baker, Her special licence that I, the said George Baker,
my executors, administrators, and assigns, or such others as I, the said
George Baker, 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 METALLIC LATTICE OR TRELLISWORK," a communication
from abroad by Owen Carraway, late of New York, upon the condition
(amongst others) that I, the said George Baker, my executors or adminis-
trators, 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 George Baker, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, 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: metallic lattice or trelliswork.
Heretofore in the manufacture of such
descriptions of work it has been usual to employ straight wires or rods,
which at their intersections are tied with thin wire, or else the wires them-
selves are twisted or interlaced at their intersections. Now, this Invention
consists in causing the wires or rods, whether cylindrical or of other section,
to be first corrugated, and then to be combined by each corrugated wire or
rod being passed alternately under and over the neighboring corrugated wires
or rods, by which means, at the intersections of the several wires or rods, two
hollows or bends will come together in each case, by which they will without
being tied by small wires, and without being twisted, be prevented sliding
or moving out of position at the angles or intersections. In preparing the
wires or rods for these purposes, it is preferred to employ a corrugating
machine, consisting of two parallel axes driven by any suitable power, each
having a similar toothed wheel thereon, the teeth of which gear together;
such teeth being formed with a rounding surface, corresponding with the
bends or corrugations desired to be given to the wires or rods.
Having thus stated the nature of the said Invention, I will proceed more
fully to describe the manner of performing the same. In constructing
metallic lattice or trelliswork the wires, or rods used are caused to be first
corrugated or bent with alternate bends as is shown at Figure 1; the bends or
corrugations being made of a width depending on the object to be accom-
plished. The corrugated wires or rods may be arranged diagonally, or at
right angles to each other, according as the lattice or trelliswork is desired
to be formed with meshes or openings bounded by sides at right angles to
each other, or by sides inclined to each other. Figure 2 shows a piece of trellis
or latticework, with the corrugated rods or wires set or intersecting each other
diagonally; and Figure 3 shows a piece of trellis or latticework, the corrugated
rods or wires of which are set or intersect each other at right angles to each
other. In each case, by reason of the bends of the wires or rods coming
together where they intersect or cross each other, they are prevented sliding
or moving out of their proper positions. Each corrugated wire or rod used in
constructing trellis or latticework is caused alternately to pass over and under
the other corrugated wires or rods; or, in some cases, straight wires or rods
might be used with corrugated wires or rods, but it is preferred that all the
wires or rods used, except those which are applied round the edges, should be
corrugated or formed with bends where they intersect each other; but even
those rods or wires round the edges may, when desired, be also corrugated or
bent with alternate bends. The wires or rods are bent or corrugated by a pair
of toothed wheels or rollers, the teeth of which take into each other, leaving,

page_text: however, sufficient space between the teeth to admit of the thickness of wires
or rods to pass between their surfaces. What I claim is, the manufacture of
metallic trellis or latticework, by applying wires or rods formed with corru--
gations or alternate bends, as herein described.
In witness whereof, I, the said George Baker, have hereunto set my
'hand and seal, this Twentieth day of December, in the year of our
☐ Lord One thousand eight hundred and fifty-nine.
GEORGE BAKER. (L.S.)
