IMPROVEMENTS IN MEANS OR APPARATUS FOR THE MANUFACTURE OF LACE FABRICS."
Year: 1862

page_text: LETTERS PATENT to James Hartshorn, of the Mansfield Road, Notting-
ham, Lace Manufacturer, and William Redgate, of Nottingham, Draughts-
man, for the Invention of "IMPROVEMENTS IN MEANS OR APPARATUS FOR
THE MANUFACTURE OF LACE FABRICS."
PROVISIONAL SPECIFICATION left by the said James IIartshorn and
William Redgate at the Office of the Commissioners of Patents, with
their Petition, on the 8th September 1862.
We, JAMES HARTSHORN, of the Mansfield Road, Nottingham, Lace Manu-
facturer, and WILLIAM REDGATE, of Nottingham, Draughtsman, do heroby
declare the nature of the said Invention for "IMPROVEMENTS IN MEANS OR
APPARATUS FOR THE MANUFACTURE OF LACE FABRICS," to be as follows:-
The improvements relate to means for the production of what are called
scolloped edges," and also extensions or contractions to holes and other parts
of lace fabrics. For this purpose, in addition to the ordinary points, I employ
another or other bars of points below the ordinary points, and such extra
point bars in addition to their backward and forward motion, are capable of

page_text: endway motion regulated by jacquard or other pattern surface, so that theso
points may operate upon threads to draw them sideways to the extent
desired, and they are placed in position to enter between the threads just
above the carriages, when the desired endway motion may be given to such
extra points to draw the threads sideways till taken and held by the ordinary
points, and so on until the desired deviation from the otherwise regular course
of the threads has been attained.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Hartshorn and William Redgate in the Great Seal
Patent Office on the 7th March 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
HARTSHORN, of the Mansfield Road, Nottingham, Lace Manufacturer, and
WILLIAM REDGATE, of Nottingham, Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of September, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said James Hartshorn and William Redgate, Her special licence
that we, the said James Hartshorn and William Redgate, our executors,
administrators, and assigns, or such others as we, the said James Hartshorn
and William Redgate, our 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 "IMPROVE-
MENTS IN MEANS OR APPARATUS FOR THE MANUFACTURE OF LACE FABRICS," upon
the condition (amongst others) that we, the said James Hartshorn and William
Redgate, our executors or administrators, by an instrument in writing under
our or their hands and seals, or under the hand and scal of one of us or
them, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to bo 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 we, tho said James Hartshorn and William
Redgate, do hereby declare the nature of the said Invention, and in what

page_text: manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, that is to say:-
The improvements relate to means for the production of what are called
"scolloped edges," and also extensions or contractions to holes and other parts
of lace fabrics. For this purpose, in addition to the ordinary points, we
employ another or other bars of points below the ordinary points, and such
extra point bars, in addition to their backward and forward motion. are
capable of ondway motion regulated by jacquard or other pattern surface, so
that these points may operate upon threads to draw them sideways to the
extent desired, and they are placed in position to enter between the threads
just above the carriages, when the desired endway motion may be given to
such extra points to draw the threads sideways till taken and held by the
ordinary points, and so on until the desired deviation from the otherwise
But that the nature of tho
regular course of the threads has been attained.
improvements may be better understood, we will proceed, by the aid of the
accompanying Drawing, more fully to describe the same.
Figure 1 shews a Diagram, full size, of some of the working parts of a lace
machine with bars added thereto according to our Invention; Figure 2 shews
a Diagram looking at the front of the parts, shewn by Figure 1, with lace
bring produced partly according to our improvements, and partly in the
ordinary way.
a, a, are the ordinary front and back point bars with their points a'; b, a
bobbin and carriage carrying bobbin thread b'; c, warp threads; d, d, are
combs in which the carriages 6 move backward and forward, as is well under-
stood; e is a front scolloping bar; and e' a back scolloping bar, which,
according to our improvements, are placed to operate by their points e' on the
bobbin threads between the taking-up points a' and the carriages. And we
would here remark, that although we have shewn two bars of points e and e¹,
only one of such bars will in many cases be sufficient, but other number of
them may be used. And in order that their operation may be better under-
stood we will suppose the machine is closed by the carriages being in the
centre, as shewn by the Diagram, Figure 1, and the points of the bar e¹
bave entered through the threads to the extreme left (or right, as the case
may be) of those to be operated. and then by this bar being shogged end-
ways, it will push all those threads to the right (or left as the case may be) to
the extent desired, when the back point bar a will enter, and keep those
threads thus drawn on one side in that position, as indicated at B, Figure 2.
when the bar e will be withdrawn until the motion for forming that row of

page_text: loops or meshes of net has been completed, when the other bar e is brought
into operation in like manner, and so on from left to right and then from
right to left alternately to the extent and in the order desired.
The Diagram, Figure 2, as already stated, illustrates two breadths of lace
with pattern as made with one breadth A thereof produced in the ordinary
way, and the other B. According to the improvements the dotted red lines
on the part B shew the bobbin threads as they would appear after having
been in operation, producing part of a scollop just before a bar of points e or e
enters between them, and is shogged endways, and the full red lines show
those threads after such bar of points has been shogged endways to the extent
desired.
In the illustration given it is supposed that the desired extent of scollop is
obtained by successive operations upon the bobbin threads by the extra points,
but in some cases the whole extent of expansion or contraction may be
obtained at one operation. When holes or tissue are required to be acted
upon to produce contractions or expansions, the operation of the bars of extra
points e, e', is similar, except that in place of their being applied to act on the
edge of each breadth of lace they act on it at the parts required.
The bars of extra points e and e' are shewn supported upon the front and
back catch bars by pins or studs in those catch bars passing through the
bars e and e', and when so applied, the holes in the bars e and e' will be
slotted in the direction of the length of those bars to admit of their moving
endways to the extent desired, and the endway motion to them may be
obtained by cams, or wheels, or levers operated by the jacquard to pull them
in one direction whilst they are drawn in the opposite direction by springs, as
is the practice in giving endway motion to other bars employed in laco
machinery. But in place of the bars being supported on the catch bars, and
moved to and fro with them, they may be supported otherwise, and have
motions to and fro as well as endway altogether independent of the other
moving parts.
It will readily be understood by persons acquainted with the working of
lace machinery, that in order to obtain the results desired, it will only be
necessary to operate by the extra points upon the bobbin threads, as the warp
threads may readily be shogged to the extent desired endways of the machine
by the ordinary means in use for that purpose.
Having thus described the nature of our said Invention, and means
which we adopt in carrying the same into effect, we would have it understood
that we do not confine ourselves to the details referred to, which may be

page_text: varied; but what we do claim is the application of extra bars of points to
operate on the threads between the ordinary taking-up points and the carriages,
in manner substantially as explained.
In witness whereof, we, the said James Hartshorn and William
Redgate have hereunto set our hands and seals, this Fifth day of
March, in the year of our Lord One thousand eight hundred and
JAMES HARTSHORN. (L.B.)
WILLIAM REDGATE. (L.s.)
