Year: 1825

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
NUNN and GEORGE FREEMAN, both of Blackfriars Road, in the County of
Surry, Lace Manufacturers, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Fifteenth day of March, in the sixth year of His
reign, did, for Himself, His heirs and successors, give and grant unto us, the
said Henry Nunn and George Freeman, His especial licence, that we, the said
Henry Nunn and George Freeman, our exors, admors, and assigns, or such
others as we, the said Henry Nunn and George Freeman, our exors, admors,
and assigns, should at any time agree with, and no others, from time to time
and at all times during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, our Invention of "CERTAIN IMPROVEMENTS IN MACHI-
MERY FOR MAKING THAT SORT OF LACE COMMONLY CALLED BY THE NAME OF 'BOBBIN
NET;" in which said Letters Patent there is contained a proviso obliging us,
the said Henry Nunn and George Freeman, by an instrument in writing
under our hands and seals, or under the hand and seal of one of us, particularly
to describe and ascertain the nature of our said Invention, and in what
manner the same is to be performed, and to cause the same to be inrolled in
His Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in

page_text: and by the same, reference being thereunto had will more fully and at large
appear.
NOW KNOW YE, that in compliance with such proviso, I, the said
George Freeman, do hereby declare the nature of our said improvements
in machinery for making that sort of lace commonly known by the name of
bobbin net are particularly described and ascertained by the annexed sheets
of Drawings or Plans. And in the following description thereof (that is to
say):-
Before I explain our improvements I have to observe, that they are more
particularly applicable to the machine now in use called the traverse warp,
which machine is too well known to require any further illustration or expla-
nation than such as is necessary to shew and explain the application of such
improvements.
Fig. 1, pl. 1, represents an end view of our improvements, and such parts
of the traverse warp machine now in use, as are necessary to be shewn in
order that such improvements may be well understood. Fig. 2, pl. 2, repre-
sents a transverse section of the same, with the compound cam wheel R, that
actuates the carriages by the connecting parts, as will be explained hereafter.
Fig. 8, pl. 3, represents a front view of the same. Fig. 4, pl. 4, a plan for
actuating the point bars. Fig. 8, pl. 4, a bobbin and carriage full size. Fig.
9, pl. 4, a side view of a lead of combs, full size. Fig. 10, pl. 4, shews the
improved apparatus for effecting the traverse of the spole threads. Fig. 11,
pl. 4, is a side view of U; Fig. 10. Fig. 5, pl. 3, shews the relative position
of the three cam wheels, R, b, g; the blue lines shew the cam R to actuate
the carriages, the red the cam, b to actuate the traversing apparatus; the
green lines the cam 9 to actuate the points, and the purple shews the shaft S.
Fig. 7, pl. 3, represents a top and bottom jack w, x, and two locker bars y, z,
full size, being an improvement on those hitherto in use. Fig 6, pl. 3, repre-
sents more plainly a top jack, full size, the bottom jack is plainly seen at x,
Fig. 7, pl. 3. The same letters of reference are used to denote corresponding
parts in all the Figures. The standards of the frame are shewn in Figs. 1, 2,
and 4, by the outline parts in Fig. 3 by a star thus. Fig. 2, pl. 2, A is the
bobbin and carriage which work in the arc of a circle on and between the
combs B, B, which are cast in the leads C, C, which leads are screwed on the
bars D, D, at each end of which are cross bars E, E, and the adjusting screws
F, F, F, F, which rest on the standards at each end of the frame at G, G.
H is a quadrant working on the axle I, having two pushing bars J, J, screwed
on to it, and a like quadrant at the opposite side of the machine, and extend-
ing from side to side. K is an arm connected with a like arm of the opposite

page_text: quadrant by the bar L; which bar is connected by the rod M with the
treadle N, which works on the axle O, and has a truck at P, which truck
works in the groove Q, Q, Q, Q, Q, of the compound cam R, which is fixed
on the shaft S; the arms K are not shewn in Fig. 8, in order to avoid confusion.
The needle bar is the same as that now used. This concludes the parts to
effect the twisting.
I now proceed to explain the parts to effect the traversing of the spole
threads. T is an angular bar similar to the top fork bar now used, on which
the leads of traversing points U are screwed, as shewn at full size at Fig. 10.
The framing U', to carry this bar, may be the same as that to carry the two
fork bars now in common use, the axle V (see Fig. 10) of the bar T is
borne by a spiral spring against the indented piece of steel W (to be called
the shog plate); which shog plate is fastened to the end standard of the frame
in such a manner as to be parallel with the motion of V. The apparatus
herein last explained effects the traversing of the spole threads with greater
ease and security than the complicated machinery now in common use. The
framing U of the traversing bar (see Fig. 1) is connected by the rod X to
the treadle Y, which works on the axis Z, has a truck (a), and is actuated by
the cam (6), which revolves with the shaft S. The point bars are the same
as those now in common use, and are connected (see Fig. 4) by the rods (c, c,)
with the treadles (d, d) which work on the axles (e, e,) have trucks at .(f.f.)
and are alternately actuated by the cam (9), which revolves with the shaft S.
A', Fig. 8, is a rigger, over which the band from a drum runs from some first
mover. B' is a pinion. C' is a cog wheel fixed on a shaft S. In order to
actuate the machinery heretofore explained the pinion B, Fig. 8, is caused to
revolve by some first mover acting on A', and gives a rotary motion to the
cog wheel C and the shaft S and the cam wheels R, b, g. The point h on
the cam R (Fig. 2) is supposed to have moved from i to h, and has by the
truck at P running in the groove Q, Q, Q. Q, Q, of the cam R, thereforo
raisd the unfixed end of the treadle M; which is connected by N, L, K, with
the quadrant H; and the front pusher bar J and the carriages have been
pushed by J from the front combs into the back; the needle bar now shogs to
the right in the usual manner'; the cam R continuing to revolve, gradually
presses down the lever M till the point j gets over P, which causes the-back.
pusher bar J to push the carriages through the threads into the front combs,
the needle bar shogs to the left, the cam causes the front pusher bar J to push
the carriages into the back combs, and the needle bar-shogs to the right; the
carriages now remain stationary on account of the dead run from k to l'on the
cam R, and the traversing commences; the projection 6, Fig. 1, on the.cam b,

page_text: passing to the point (n) over the truck (a) presses down the unfixed end of
the treadlo Y, which by the rod ✗ is connected with the frame Us, which
carries the angular bar T, on which are screwed the leads of traversing points;
these, therefore, being carried forward take the threads out of the dividers, the
front row in the shallow division as far as the line o (see Fig. 10), the back
threads in the deep division as far as the line p; the threads being thus kept
one row before the other, the angular bar T has on return to its former place,
which as the cam 6 (see Fig. 1) passes on permits it time to shog between the
delivery of the back row of threads into the dividers and the front ones, which
shogging is effected by the axle V of the angular bar T (see Fig. 10) passing
over the shog plate W, from 9 to r, against which it is borne by the elastic
springs; a divider is pulled out between each breadth, as is now customary;
the front points are now to be put up the recess t on the cam wheel g, Fig. 4
presents itself before the right-hand truck f, which pressing against the cam
allows the treadle d to approach the shaft S, and the points to draw out of the
threads; the projection u, now acting against the same truck, drives back the
treadle which forces up the front points, and after the point v has passed the
same truck allows the points to return to their first situation; the point bars
work the same way as those in common use; and the mode of actuating them
being so very similar to the common heart motion of the engine used to winds
lace thread, needed but little explanation. This finishes a course.
The same
movements are repeated for the next, except that the carriages are first pushed
from the back combs and finish in the front, and the back point bar is actuated
by the cam g instead of the front. The two courses are then alternately
repeated (ad infinitum). If at any time it may be desirable to work a machines
constructed with these improvements, or any of them, by manual labour, a
handle may be fixed on the bar L, and treadles, the same as those now in use
attached to the traversing and point bars, and the shaft S, the cog wheels,
rods, cams, and treadles be dispensed with. The most convenient mode of
constructing the leads of traversing points appears to be by casting a set of s
points according to the guage, and on every alternate division a piece of flat
wire to project from the lead U, as far as the line O (see Fig. 10 & 11).
Fig. 6 & 7 is an improvement on the jack and locker now in use; the blades
of the jacks w and are made with a step, and the lockers y and being
made to fit, hear on the extremities of the jacks a, a, and prevent the
drooping of the same now so much complained of; the lockers may be actuated
by the same mode as is now used.
Having described our improvements and their application in such a manner
as to enable persons conversant with lace machinery to put the same in

page_text: practice, it remains for me to state what we consider as constituting our claim.
We claim the mode and apparatus herein described for traversing the spole
threads exclusive of the framing which is old. We claim the mode and
apparatus herein described for working a single tier of carriages on and
between circular combs. We claim the improved jack and locker herein
described, to be used in a traverse warp machine. We claim these jointly and
separately, whether actuated by power or manual labour.
In witness whereof, I, the said George Freeman, have hereunto set my
hand and seal, this Fifth day of September, in the year of our Lord
One thousand eight hundred and twenty-five.
GEORGE (Ls.) FREEMAN.
AND BE IT REMEMBERED, that on the Fifth day of September, in
