page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, JOHN
HEATHCOAT, of Loughborough, in the County of Leicester, Lace Manufac-
turer, sends greeting.
WHEREAS in and by certain Letters Patent under the Great Seal of the
United Kingdom of Great Britain and Ireland, bearing date the Fourteenth day
of July, in the forty-eighth year of the reign of His present Majesty King George
the Third, it is recited that I, the said John Heathcoat, had, by my Petition,
humbly represented that I had, after much labour, study, and expence, found
out and invented "A MACHINE FOR THE MAKING OB MANUFACTURING OF BOLBIN
LACE, OR LACE NEARLY RESEMBLING FRENCH LACE, BY MEANS OF WHICH SUCH LACE
WOULD BE MADE TO MUCH GREATER ADVANTAGE THAN BY ANY OTHER MODE HITHERTO
PRACTISED, AND FROM THE USE OF WHICH WOULD RESULT A CONSIDERABLE DECREASE
OF EXPENCE, BEING CALCULATED TO PROMOTE AN EFFECTUAL SAVING IN TIME AND
LABOUR," which I conceived, from repeated experiments, would be productive of
great public utility; that I was the first and true Inventor thereof, and that
the same had not been made or used by any other person or persons whomso-
ever, to the best of my knowledge or belief; and I therefore most humbly
prayed that His said Majesty would be graciously pleased to grant unto ine,
my exors, adñiors, and assigns, His Royal Letters Patent under the Great Seal
of the United Kingdom of Great Britain and Ireland, for the sole use, benefit,
and advantage of my said Invention within that part of His said Majesty's
United Kingdom of Great Britain and Ireland called England, His Dominion

page_text: of Wales, and Town of Berwick-upon-Tweed, for the term of fourteen years,
pursuant to the Statute in that case made and provided; and His said Majesty,
being willing to give encouragement to all arts and inventions which might
be for the publick good, was graciously pleased to condescend to my request:
Therefore His said Majesty, of His special grace, certain knowledge, and mere
motion, did give and grant unto me, the said John Heathcoat, my exors,
admors, and assigns, His especial licence, full power, sole privilege and
authority, that I, the said John Heathcoat, my eñors, adñors, and assigns, and
every of them, by myself and themselves, or my or their deputy or deputies,
servants or agents, or such others as I, the said John Heathcoat, my exors,
admors, and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend my said Invention
within that part of His said Majesty's United Kingdom of Great Britain and
Ireland called England, Ilis Dominion of Wales, and Town of Berwick-upon-
Tweed, in such manner as to me, my exors, adññiors, and assigns, or any of
them, should, in my or their discretion, seem meet; and that I, my exors,
adñiors, and assigns, should and lawfully might have and enjoy the whole
profit, benefit, commodity, and advantage from time to time coming, growing,
and arising by reason of the said Invention, for and during the term of years
therein mentioned; to have, hold, exercise, and enjoy the said licence, powers,
privileges, and advantages therein-before granted or mentioned to be
granted unto me, the said John Heathcoat, my exors, adñiors, and assigns,
for and during and unto the full end and term of fourteen years from the date
of those Presents next ensuing and fully to be complete and ended, according
to the Statute in that case made and provided; and it was thereby provided,
that if I, the said John Heathcoat, should not particularly describe and
ascertain the nature of my said Invention, and in what manner the same was
to be performed, by an instrument in writing under my hand and seal, and
cause the same to be inrolled in His said Majesty's High Court of Chancery
within one calendar month next and immediately after the date of the said
Letters Patent, that then the said Letters Patent, and all liberties and advan-
tages thereby granted, should utterly cease, determine, and become void.

project forward. I represents a bar or plate of brass cut into parts, every
part of which is screwed, to the iron bar K. by two screws, and a pin is put
into the iron bar near cach end of every part, upon which pins the parts of I
are put, whereby they are kept in a certain position, and if taken off are sure
to be put in the same places. Again, the bar or, plate I is divided into sixty
equal divisions, and a holo is drilled at every division to receive the pivot d of
the pinion N. Care must be taken that these holes are at exactly equal distances
and in a direct line. This bar is supported by 61, 61, the ends a of which are
screwed to I. J represents a bar or plate similar to I, but not cut. Holes
are likewise drilled in this bar to receive the end d of the pinion N, every hole
being in a direct line from the holes in I to the centre. This bar is supported.
by a 2, a 2, and 62, 62. K represents the iron bar to which I is screwed,

A hole is drilled in at
the end a, and down the middle of the pinion to d, where it is let out.
At o
is a small hole drilled to pin on the bottom part of W. N 1 is the short
pinion, and N 2 the long one; the head of one is made to miss the head of
the other, and the collet the same. The collet is filed away on the side on
which the holes are let out at d. O represents two slides or racks cut full of
teeth to correspond with the pinions so as to turn the pinions. In the middle
of the back edge of the slides is a projection a, cut in a similar manner as the
other edge, which teeth are for the racks t1, t2, to work in. P represents a
bar, either cast iron or made by screwing two bars of a proper form together.
To this at each end is screwed p 1, and to p 1 p 2. Inp 2 are holes to receive
the centre or pivot of the screw in b 1. Upon this pivot P is suspended, and
moves upon them as a centre. This bar is placed in such a situation that the
elge a bears against the flat side of the collets of the pinions, and is forced up to
the collets by two springs p 3, which are screwed to the plank of the wood
frame. The back part of P is connected by a wire with the lever j, j 3, fixed
on the standard J, J. From the end c of the lever is a wire down to a treadle

hole at a of k, k 1 is put. t 2 is another rack, the same as t 1, except, instead
of the spindle t 3, the socket t 4 is fixed in. Through this socket is a hole to
receive the spindle t 3. U represents half a taper split spindle. N represents half
a taper split tube. W, U, and V are soldered together. At a the brass ferrule
to 1 is soldered. In the round side of W is a groove cut up to c, where a hole
is drilled through, and a groove is cut on the flat side, from thence to near the
point e. In the middle of the point e is a small hole drilled into the said

page_text: Z

groove at b. The edges are filed away to admit the parts e of g, g 1, and at ca
pin is fixed in W. At d there are two small pieces of latin brass dovetailed
in the flat side of the spindle, to prevent the thread from flying out of the
groove. X is U and V soldered together. A is filed as represented in the
Drawing. At 6 the ferrule x 1 is soldered, into which the bobbin x 2 is put.
Atc the ferrule 8 is soldered. At d the small brass tube 2 4 is soldered, on the
narrow part of the tube. The spring . 5 is put in the hole of the tube. The
needle 6 is put at c; the edges are filed similar to 6 of W, but not so long..
At there is a hole to be put on the pin at c of W. At g there are two small
pieces of latin brass, the same as at d in W. The point h is drilled the same
as the point e of W. Y represents the bottom single part of the spindle
compressure made by screwing a plate of brass to a plate of iron. The brass
projects about half an inch forwarder than the iron. To Y, Z is screwed,
which is the top single part of the spindle compressure, made in the same
manner as Y. The edges of the brass in Y, Z, are so disposed as to enter the
grooves between the brass of L and M. At the part a is a hole into which
the point of the screws at a in d 3 enters; and on this point
suspended.. y 2 is screwed to Y, and to y 2 is screwed y. 3.
a pin is fixed, on which pin the hole at a of y 4 is put. A, A, represents a
bar screwed to the back of the wood frame, on which is screwed a, a 1. In
a, a 1, is a screw, on the point of which the hole ate of B, B, is put. B, B,
represents the frame in which the crank bars are fixed. At a is a slit in which
b, 61, is fixed. In b, b 1, is a hole to receive the end of the spindle c, c 1 ;
and on b, b 1, is screwed the plate b, b 2, with a hole to be put on the small
part a of the spindle. This plate holds the spindle back at b.
screwed. In b, 63, is a slit, in which b, b 4, is fixed. In b,
receive the end d of the spindle c, c, 1. At c holes are drilled to receive the
points of the screws in a, a 1. C, C, represents a crank bar at a; the spindle
c, c 1, is fixed, and in the ends b are pins. D, D, is similar to C, C, except
that it is larger; and instead of the spindle c, c 1, is a socket d, d 1. This
socket has a hole to receive the spindle c, c 1. The ends of the spindle c, c 1,
are put into the holes at 6, 61, and b, 64, by which these bars are suspended.
E, E, represents the bottom bar arms, the holes in the ends a of which are put
on the pins in b of C, C. To the end 6 is screwed the bar G, G. F, F, repre-
sents the top bar arms. At the support f, f 1, is fixed, the part a, a, of which,
bears close to the levers g, g 1. The holes at a are put on the pins at 6 of
D, D; and to the end bis screwed the bar G, G. G, G, represents a bar on
which the levers g, g 1, are screwed. The rims a, a, project above the middle
of the bar, that the levers may bear on each rim, and not the whole breadth of

lever bar G, G, and another on the
Holes are drilled in the rims to screw the plates g, g 2, which plates
hold the levers steady, but not so as to prevent their moving sideways. In the
middle of the bar G, G, are pins on which the levers are put. 9, y 1, is the
forked lever; 9, 91, A, is the bottom bar lever; and g, g 1, B, is the top bar
lever. At a is a hole to be put on the pin in G, G. At b is a pin to work
between two pins in H, H. At c is a hook g, g 3. At the spring 9, 94 is
rivetted upon it, and at e the end is cut in the manner described. When these
levers are fixed to work, the part e is put into the cavities b and c of X and W,
and the hook at c is made to go under the end a of X. Then, by raising the
machine, which is done by bearing down the treadle No. 6, the points e pass
behind the shoulders at the top of e at X, and the hook 9, 93, passes behind
the end a of X; then raise the part Y and Z of the spindle compressure by
bearing down the treadle No. 1, and bring forward the bar G, G, by which
motion the levers g, g 1, bring the spindles X from off the spindles W, which
are then held entirely by the fork e and the hook 9, 9 3, of the said levers, and
are kept steady by the spring 9, 94, the hollow part a of which embraces
the round part of X. g, g 1, C, represents a jointed lever, one of which is
fixed on the right side of the bottom
left side of the top lever bar G, G. They are jointed, that the ends and
the hook g, g 3, may be moveable. They are held in a right position by a spring
rivetted on the back of the lever. On F1 are two springs b, to hold the upper
end of these levers to the spindles. II, II, H, represents the lever conductor,
consisting of the bar II, II, and the directors h, h 1, and the part h, h 2.
II, II, is fixed in front of the levers 9, 91. Above the plates 9, 92, the ends a
turn round the edge of the bars E, E, and the ends of a similar bar turn round
the edge of the bars F, F. The parts h, h 1, are put behind the plates g, g 2,
to keep II, II, back to the levers. The part h, h 2, is a square staple fastened
to H, H, by two screws at d, which passes down behind the plates 9, 9 2. To
raise H, H, the end a of the thumb plate bears against the bottom of h, h 2,
and forces it upwards. The space e between the pins in H, II, is made a proper
width to receive the pin at 6 of g, g 1, and is made in the direction represented.
To conduct the end e of the lever aslant, according to the direction of the
spindle the fork is intended to take, when the bar G, G, is raised, H, I, does
not rise, and therefore the pins at 6 of 9,9 1, are forced inward; and when
G, G, is held forward the levers continue in the same position as they
were before taken out of the spindles W, and when G, G, is put back
again, whereby the spindles a are put on, W and G, G, sinks by taking
the foot of the treadle No. 6. II, H, will continue in the same place as
before, that is, it will not sink, whereby the pin at G of the lever g, g 1,

page_text: will be forced outward. b and c are stops screwed to h, h, 1.. I, I, repre-
sents the bottoni bar conductor standard screwed to the plank on which
the conductor i, i: 1, is screwed. In i, l'are notches cut to receive g, g 5,
of the bottom by g, g. These notches are cut at proper distances, to conduct the
levers to separate spindles; (that is to say;) if the levers are on the spindles
when the part "g; g 5, of G, G, is in notch' 1; then notch 2 is made, so that
the levers will go on in the next spindle by g, g 5, of G, G, entering into the
said notch, and so of 3. J, J; represents the back standard screwed to the
back edge of the plank on which is fixed j, j-1, with screws at a, a, to stop the
racks. At b is a pin on which to put the hole at a of the lever j, j 2, which
lever is connected at the hole at b to the end a of g 4, and the other end c
of the lever is connected with the treadle No. 4 by a wire. By bearing down
this treadle the bar S is drawn back, which draws the notches of the slides.out:
of the pinions, by the parts d of s 4 and t 5 being behind the shoulders 6 of
the projection a. At a is another pin on which the hole at a of another lever,"
like j, j 2, is put. This lever is connected at 6 with the end a of b, b, 8; and
from the end c of this lever a wire descends to the treadle No. 6. By bearing
down this treadle the lever bar G, G, is raised. At c is a pin on which the
hole at a of the lever j, j 3, is put, the end 6 of which is connected by a
wire to the bar P, and the other end is connected by a wire to the treadle.
No. 5. By bearing down this treadle the bar P is drawn back from the
collets. K, K, represents two levers fixed on a pin put into the back edge of
the plank. At 6 there is a pin on which the hole at 6 of k, k 1, is put, and
at the other end at a is a hole in which the cord is fixed, which passes over
a pulley in the under side of the plank, over the treadles 2 and 3, to
which the cords are also fixed. L, L, represents a bar fixed on the points
of the screws at a in 1. At a the tail 1, 1, is screwed to it, and at b are
pins in which the holes at 6 of y 4 are put. The other end of y 4 is put
through under the bar 6 to the single compressure y. On the pin at a of y 3
the holes at a of y 4 are put. M, M, represents a lever fixed on the
support m, m 1, by the hole at b being put on the pin at 6 of the support.
The end a is connected to the tail 1, 1 1, by a wire fixed to the hole at a; the
other end of this lever is connected to the treadle No. 1 by a wire. By bearing
on this treadle the top compressure Y, Z, is raised. The part a of m, m 1, is
screwed to the back of the top part of the wood frame.
regulator of the work screwed to the back of a, a 1.
between a and b. The screw in the end of g 1 bears against a, which screw is
regulated to prevent the points h 2 from coming too forward. A spring is
fixed to the end d of g 1 to hold it up, and also to hold it forward. In 6 are
N, N, represents the
The end c of g.1 is put

page_text: notches, so that when the end of g 1 is put down the notches prevent it from
rising again till it is taken back by the lever e, the end c of which is connected
to treadle No. 6, which raises the machine. Whenever 9 1 is lowered a notch,
the end of d of this lever catches against the end d of g 1, and bears it back
till the part of g 1 is out of the said notch, when it rises up to the top
screw f, and slips forward. The screw f is regulated to direct the points a
proper height to enter the hole in the work, which wants crossing to make it
complete. O, O, represents the bottom bar handle screwed to the part b
of G, G. The part a of the thumb plate pushes up the staple h, h 2. The
part is a conducting pin to the top bar G, G. In the bottom bar G, G, the
conducting ping, g 5, is fixed, the end of which enters into the notches
of i, 1. is a plate screwed to the part 6 of the top bar G, G. This plate has
notches similar to i, i 1, but wider asunder. In these notches the part 6 of o, o,
works. Upon this plate, by the same screws, the top bar handle P, P, is fixed.
The thumb plates are to raise the lever conductor II, H, preparatory to pulling
them into the spindles. Q, Q, represents the point director. Between the wires
the points 2 are put, and by the slanting direction of the wires the said
points when raised are forced inward, by which means they draw the thread
equally from the points of all the spindles. As the motions of the machine are
gone through twice to make a mash, it is necessary to shift the points h 2
sideways every time they are drawn out of the work; first right and then left,
alternately, which is done by the parts 7, 72, screwed on H, which, when the
bar II is born back, bears against the bottom of the parts a, which parts are
screwed to Q, Q, but not fast. 9, 91 is a lever fixed on d 2, the end a of
which rests upon the end 6 of D, D, so that when D, D, moves, the lever
moves also. At bare pins when the end of the lever bears against the top part
of a, which are made aslant, and by bearing against the said part moves the
top part inward, by which the bottom is prevented from being pushed up
by 9, 92. The other end of the lever being up, the pin does not bear against
the top part of a, so that the part q, q 2, bears against the bottom of a, which
causes Q, Q, to move sideways, the part 6 of which is shifted a notch of
the spring 9, 93, which notch is made to shift the points h 2 equal to the
breadth of the point of the spindles. The end of the lever, which is up one
time, is, by the regular way of working, down the next, by which Q, Q, is
moved to the contrary side, and so on alternately.
To put the thread to the machine preparatory to working, put the same number
of threads on the bottom woeden roller as there are pinions; put the end of every
thread through the holes from a to d in the middle of the pinions, and let it
lic in the groove in the round side of the spindle or tube to c, where it is put

page_text: through, and it then passes in the groove in the flat side of the spindle W at d;
put it behind the lattin brass, and through the hole in the point e; then fasten
them all to the top wooden roller; wind thread upon the bobbin a 2; put it in the
ferrule 1 of ; put the end of the thread through the ferrule a 3; bring it up
on the outside of the spring and tube x 4 and x 5; put up the needle x 6; put
the thread through the eye of the needle and through the hole at d, and back
through the hole at f; bring it up the groove; put it behind the lattin brass
at g, and through the hole at the point h; the springs x 5 must be regulated to
hold the threads equally tight; put the spindle upon the spindle-W, and
fasten the thread to the top roller; fix the parts Y and Z of the spindle com-
pressure on L and M, and fix a wire spring to the end a of 1, 1; the other
end of the spring is fastened to the plank; fix a cord to the end c of the racks
pass this cord over a pulley fixed at the end of the wood frame in a line with
the rods K, K; to this cord hang a weight heavy enough to bring the ends c of
the racks 1 and 2, when the slides are held out of the pinions, to the stop
in a of jj 1; fix two springs upon the blank behind the machine similar
to 3; make these springs bear against the upper ends of 9 1, and make the
gage screws in 9 1 bear equally against the bar S, so that the spring will force
the teeth of the slides O into the teeth of the pinions; screw on the catch t 5
upon the top of T, and s 4 upon s 3, the parts d of which must be fitted to
close over the edge 6 of the projection of the slides to the end c of 8 3; screw
the part s 5, the part a of which passes behind the upper part of g 3, so that
when the bar Q is born back it draws the slides out of the teeth of the
pinions. To twist the threads, draw back the bar P, which is done by the
treadle No. 5, and bear down the treadle till the end c of the racks stop
against the screws at a of j, j 1. To make common bobbin lace, fix the screws
to let the racks move enough to turn the pinions twice round, but the lace is
better if it has another round. It requires the slide, which works one half of
the pinions, to turn them twice round, and the other half once, and the next
time of twisting those which were turned once round last time must be
turned twice round the next, and those which were turned twice round last
time must turn once round, and so on alternately. This is done by bearing
down the treadle No. 2 one time and the treadle No. 3 the other. The screws
in the part d of the racks are fixed, so that when one of the
the pinions turn once the screws bear against the other rack.
let the bar P bear to the colletts of the pinions; put in the machine (by
machine is here meant the fork lever bars) so that the parts E. of the levers
enter the cavities of the spindles as before described; then raise the machine
by bearing down the treadle No. 6, and raise the parts Y and Z. by bearing
racks has made
Having twisted,

page_text: down the treadle No. 1; bring the machine forward till the point of g, g 5, is
out of the notches in i, i1; bring the top bar forward until the part of 0, 0),
is out of the notches of p, 1; then cross the bars by putting the bottom bar
to the left hand, and the top bar to the right; bear back the machine by
which the spindles X are forced upon the spindles W; take the foot of the
treadle No. 1; then let the machine sink by taking the foot off the treadle
No. 6, and bring the machine forward, which disengages the fork levers from
the spindles; then bear the bar P from the spindles preparatory to twisting
again to the treadle No. 5, which bears back P; fix a string or wire from the
end d of g 1 so as to bear down a notch of the part 6 of N, N, by which
the points are raised; when this is done, twist again. To put the bars G, G,
into a proper state for putting the levers into the spindles, put the part
9. g 5 of the bottom bar and the part 6 of o, o, into the notches 2
of the conductors i, i 1, and p, p 1; the levers will then take every spindle;
the next time put the same parts into the notches No. 3 of the conductors; the
joint levers will then be outside of the spindles, and a spindle on each side will
be uncovered by the levers. To prevent these spindles from falling off when
the parts Y, Z, are raised, the plates 71 are screwed one on each end of L,
The notches
the end c of which is fitted to lie over one spindle, and no more.
in b are cut to force the said end c to the spindle. When the outside spindles
are brought forward they force the end c forward, by which means the point
of a is forced into another notch; and when the spindles are put on again, and
the compressure Y falls back, it takes the end e back, and forces the end of a
into the former notch, by which it is again held to the spindle. The plate / 1
represented is for the left side. The right side is made the same, except the
parts being reversed, for the end c to point inward. If, instead of working one
machine single, two or more machines are desired to be worked at once by
the same hand, make the wood frame proportionally wider according to the
number intended to be put upon it, as represented in the general view, and fix
other machines to the said frame, instead of the handles O, O, and P, P, which
are fixed in the said view. To work one machine, put a pin in 6 of G, G,
and likewise in the said part 6 of the bottom bar G, G, fix a pin similar to
9,9 5, to work in the notches 1, 2, 3, of the top bar conductor in plate p, p 1;
on the pins first mentioned put the holes at a of A, represented under the
front view of the machine upon the bar A, which is fixed on the bottom lever
bar G, G; fix the handle o, o, upon the bar a, which is fixed on the pins of the
top lever bar G, G; fix P, P, behind each of these bars; fix the bar B by
screws through the slits of the said bars. These bars are placed so that the
ends of the thumb plates will bear them up, and the bottom of the staple

page_text: h, h 1, is made to come down to the top of this bar. When the thumb plates
are forced to the handles, the end a forces the bar B up, which forces h, h 1
up, and raises II, H; to the tail b, b 3, fix the bar C, which bar must be in
length according to the extent and number of the machines; and to work the
racks to move the slides, connect them to the levers K, K, by rods similar to
k, k 1, but made longer or shorter according to the distance the racks are
from the levers K, K. And to work all the other motions of the machine
which are done by the treadles, instead of only one wire being fixed to a
treadle, bring the wires from the parts which correspond in the respective
machines to the same treadle; and as there is a necessity to raise Y, Z,
whenever it is required to take off a spindle, it is proper to fix a treadle at
the proper place in every machine, which treadle is to be connected with
the part c of M, M, of that machine only to which it belongs, by which means
Y and Z are raised without disturbing the same parts of the other machine.
These machines may be made narrower or wider; but there is a difficulty
in extending them to any great width. The top and and bottom lever bars
will turn up, so that when anything is amiss with any of the threads or
spindles it may easily be rectified; and if there is more than one machine at
work, take the bar A from off the pin in b of G, G, of the machine which is
necessary to turn up, and move the part a to one extremity, and the bars G, G,
to the other extremity, whereby they are disengaged from each other and the
lever bars of the other machines. When it is necessary to take a spindle X
from off the spindle W, take a plate of iron, and bend it similar to the part a
of f f 1, but to a larger circle, and cut a notch whereabouts the spindle is
necessary to be taken off. You may have a number of plates of this descrip-
tion, with notches cut at different places, so that whenever the spindle is
required to be taken off some plate or other will be suitable to take it off
with. Fix the notches against the spindle x required to be taken off, so that
when Y, Z are raised, this spindle will come off W, but no others.
