Sealed the 29th August 1863, and dated the 5th March 1863.
PROVISIONAL SPECIFICATION left by the said Joseph Elsey at the
Office of the Commissioners of Patents, with his Petition, on the
th5 Mrach 1863.
I, JOSEPH ELSEY, of the Town and County of the Town of Nottingham,
Lace Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVED APPARATUS FOR THE WINDING OF LACE ON TO THE WORK ROLLER IN
WARP LACE, BOBBIN NET, OR TWIST LACE MACHINES," to be as follows:→
By my improvements I wind up the fabric on to the work roller as fast as
it is made on the machine, and at a certain and regular speed, whereby I insure
the fabric being of the required length, there being no variation in its tightness
or slackness when made, whereas heretofore as the diameter of the fabric on
the work roller increased, the "take up" of the work also increased, so that
the end last made was longer than the first made portion, although there was
an equal number of motions at each end.
Now my Invention consists, firstly, in using two additional rollers, the axles
of which are placed horizontally, or nearly so. The axle of the back roller is free

page_text: to turn in fixed bearings at each end of the machine; the axle of the front
roller also is free to turn in fixed bearings; or the bearings may be adjustable
vertically and horizontally. The back roller is moved round by any ordinary
method; the front roller is driven at the same speed by means of wheels at one
or both ends of the machine; or these rollers may be moved round by pulleys
at one or both ends of the machine, round which pulleys is a cross strap or
elastic belt. Besides or instead of wheels or pulleys of the same diameter, I
sometimes use wheels or pulleys of different or varying diameter to obtain a
drag upon the fabric, the front roller moving at a slightly increased speed to
that of the back roller. I sometimes cover one, or both rollers with leather,
cloth, felt, or other substance to prevent the fabric from slipping. I sometimes
press the rollers together by elastic bands on pulleys at each end, or I place
the elastic bands on each end of the rollers, by such means I obtain sufficient
friction between the rollers to constantly take up the fabric as made. The front
of the face bar of the machine is a tangent to the back of the back roller, so
that the fabric is passed up at the back of the back roller, over and round it,
to the front thereof, and under and up the front of the front roller to a
work beam placed above these rollers, and wound up by any usual methods.
Secondly, instead of or besides using plain rollers as above described, I
sometimes use fluted or toothed rollers.
Thirdly, I sometimes use two of either of the above-described rollers alone
without a third roller to wind the fabric upon, the fabric in such case being
wound upon the front roller of these two rollers, which two rollers may be
provided with geared wheels or pulleys at either or both ends thereof, the
pulleys having a straight or cross belt as described, but the axles of the front
roller, instead of being in fixed bearings, are in bearings secured to each end of
the machine, but free to move upwards and towards the front of the machine
in slots set at a proper inclination, or the axles may run in bearings attached
to swinging arms, so that as the diameter of the fabric on the front roller
increases, the friction caused by its weight upon the back roller will cause the
fabric to wind up as fast as made, the back roller being wound at a constant
rate by any ordinary method.
Fourthly, I sometimes drive the work roller upon which the fabric is wound
in the first method; or the back roller in the last method, by an elastic band
or bands on friction pulleys on each roller and on the driving shaft of the
machine.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPII
ELSEY, of the Town and County of the Town of Nottingham, Lace Mann-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of March, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Joseph Elsey, Her special licence that I, the said Joseph
Elsey, my executors, administrators, and assigns, or such others as I, the
said Joseph Elsey, 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 "IMPROVED APPARATUS FOR THE WINDING OF LACE ON TO THE WORK ROLLER
IN WARP LACE, BOBBIN NET, OR TWIST LACE MACHINES," upon the condition
(amongst others) that I, the said Joseph Elsey, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of their
bands 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 Joseph Elsey, do hereby declaro
the nature of the said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the accompanying Drawings, and
to the letters and figures marked thereon, that is to say :-
My Invention relates to apparatus for the winding of lace on to the work
roller in warp lace, bobbin net, or twist lace machines. Heretofore in such
machines as the diameter of the roll of lace or fabric wound on the work toller
progressively increased, what is called the "take up" of the work also increased,
so that the end of the lace last made was longer than the portion first made,
although there was an equal number of motions at each end; whereas by means
of my improved apparatus the lace or fabric is wound on the work roller as fast
as produced on the machine, and at a certain and regular speed, whereby I insure

page_text: that the lace or fabric shall be of the same length throughout, and without varia-
tion in respect of the tightness or slackness of the lace or fabric when made.
My Invention consists, firstly, in the arrangement or employment in warp
lace, bobbin net, or twist lace machines of certain apparatus consisting of two
additional rollers; the axles of these rollers are placed horizontally, or nearly so,
and the axle of the back roller is free to turn in fixed bearings placed one at
each end of the machine, and the axle of the front roller is also free to turn in
fixed bearings; or the bearings of the front roller may be adjustable vertically
and horizontally. The back roller is caused to revolve by any ordinary method,
and the front roller is caused to revolve by means of wheels at one or both
ends of the machine; or the rollers may be driven by pulleys and strap, the
pulleys being placed at one or both ends of the machine, and the strap being a
straight or cross strap or an elastic belt. The two rollers may be driven at the
same speed by having their driving wheels or pulleys of the same diameter, or,
instead of this, I sometimes drive the rollers by wheels or pulleys of different
diameters, so that the front roller may move at a speed slightly exceeding that
of the back roller, whereby I obtain a drag on the fabric. I sometimes cover
one or both of the rollers with leather, cloth, felt, india-rubber, paper, or other
convenient material to prevent the fabric from slipping. I sometimes press the
rollers together by means of elastic bands passing over pulleys at each end of
the rollers, or I place such elastic bands on each end of the rollers, by either of
these means I obtain sufficient friction between the rollers to take up the
fabric continuously as made. The front of the face bar in the machine forms
a tangent to the back of the back roller, so that the work or fabric may pass
up at the back of the back roller, over and around it, to the front thereof, and
under and up the front of the front roller to a work beam or roller placed
above these additional rollers, or in other convenient position with respect
thereto, and moved by any of the usual methods. The additional rollers above
referred to may be plain or smooth, or they may be fluted or toothed.
Secondly, I sometimes use the two rollers, herein-before called additional
rollers, as above described, (whether plain or smooth, fluted or toothed,) but
without employing with them a third roller or beam to wind the work or fabric
upon, and instead thereof in this case I wind the work or fabric on the front
roller of the two rollers above described, and which I call my additional rollers,
the said front roller in this case serving as a work roller or beam. The said
rollers may be driven by geared wheels or pulleys at either or both ends thereof,
the pulleys being worked by a straight or cross strap, but in this modification
the axles or journals of the front roller, instead of lying in fixed bearings, lie in
bearings fitted one at each end of the machine, and free to move upward and

page_text: of the machine worked by a cross strap or elastic belt D, as shewn in
Figure 1.
Sometimes instead of using wheels or pulleys of the same diameter which
drive the two rollers at the same speed, I use wheels or pulleys of different
diameters, so as to drive the front roller A rather more rapidly than the back
roller B, and thereby obtain a drag on the fabric.
I sometimes cover one or both rollers A, B, with a cover E, Figures, 1, 2, 3,
of leather, cloth, felt, paper, or other convenient material to prevent the fabric
from slipping. I sometimes press the rollers together by means of elastic
bands on pulleys at each end of the rollers, or I place such elastic bands on
each end of the rollers, or I attach springs to the arms carrying such rollers,
by these means I obtain sufficient friction between the rollers to take up the
fabric continuously as it is made; but I find generally that the weight of the
front roller is sufficient for that purpose, especially if the bearings in which
the journals of the front roller lie are set in a slightly raised position, in such
manner that the whole length of the front roller may lie evenly upon the back
roller.
In Figure 1 the work is shewn as passing down behind the back roller B,
under and up the front between it and the front roller A, up to the work
roller C, upon which the work is wound by means of the friction produced
by the contact between the work roller C and the back roller B, upon which
the work roller lies.
In bobbin net or twist lace machines the front of the face bar forms a
tangent to the back of the back roller B, as shown in Figures 2 and 4, so that
here also the fabric is passed up at the back of the back roller, over and around
it, to the front thereof, and under and up the front of the front roller to the
work roller C, when such a roller is placed above the rollers A, B, which roller C
is driven by any of the usual methods. When the work roller is placed
below or in front of the back roller B, the work or lace is passed up the back
of and over the back roller, between it and the front roller A, to the work
roller C, as shown in Figure 2, where the work roller is moved round by its
weight bearing against the back roller, the bearings of the work roller being
attached to a spindle bar F, so that as the thickness or diameter of the roll of
work which is being wound on the work roller progressively increases as
the same is wound thereon, the work roller will gradually rise in proportion.
F is a handle attached to the spindle bar F, by which the work roller may
be raised to draw off the work when required. On the spindle bar F are
bearings G, in which the roller A is free to turn, as seen at Figure 2, Sheet 2,
these bearings G being free to turn upon the spindle bar; these said bear-

page_text: ings G, seen in Figure 1, Sheet 1, carry the work roller. The front roller may lie
with its whole weight upon the back roller, or it may turn in swinging bearings
attached to the framing of the machine, as shown in Figure 1.
Instead of using plain or smooth rollers A, B, as in Figures 1 and 2, I
sometimes use fluted or toothed rollers, as in Figure 3. The roller B may be
driven by any ordinary method, as, for example, by a clawker or driver acting
upon one of a series of ratchet wheels at one or both ends of the rollèr, and
the work roller is driven by any ordinary mode.
Figure 4 shows an arrangement in which I use the two rollers A, B, but
dispense with the third roller C for winding the work upon, and instead
thereof I wind the work on the front roller A, which thus serves as a work
roller. The rollers A, B, may be driven by geared wheels or pulleys at either
or both ends thereof, the pulleys being worked by a straight or cross band;
but in this modification the axles of the front roller, instead of lying in fixed
bearings, are placed in bearings at each end of the machine, free to move
upwards and towards the front of the machine in slots set at the proper
inclination, or the said axles may run in bearings attached to swinging arms,
or in curved slotted bearings H, Figure 4, so that as the diameter or thick-
ness of the roll of fabric which is being wound on the front roller gradually
increases, the friction caused by its weight on the back roller will cause the
fabric to be wound up as fast as made, the back roller being driven at a
regular speed by any ordinary method.
Having now described the nature of my said Invention, and in what
manner the same may be performed, I declare that I claim the arrangement
and combination of rollers in the manner and for the purpose herein-before
described.
In witness whereof, I, the said Joseph Elsey, have hereunto set my hand
and seal, this Third day of September, in the year of our Lord One
thousand eight hundred and sixty-three.
