CERTAIN IMPROVEMENTS IN THE MAKING AND WORKING OF MACHINES USED IN THE MANUFACTURE OF LACE, COMMONLY CALLED BOBBIN NET
Year: 1824

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
DARKER MOSLEY, of the Parish of Radford, in the County of Nottingham,
Lace Manufacturer, send greeting.
WHEREAS His most Excellent Majesty King George the Fourth, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Tenth day of March, in the fifth year of His reign, did, for
Himself, His heirs and successors, give and grant unto me, the said William
Darker Mosley, His special licence, full power, sole privilege and authority,
that I, the said William Darker Mosley, my exors, adiñiors, and assigns, or
such others as I, the said William Darker Mosley, my exors, adññors, 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 Ber-
wick-upon-Tweed, and in all His Majesty's Colonies and Plantations abroad,
my Invention of "CERTAIN IMPROVEMENTS IN THE MAKING AND WORKING OF
MACHINES USED IN THE MANUFACTURE OF LACE, COMMONLY CALLED BOBBIN NET","
and in which said Letters Patent there is contained a proviso obliging me;
the said William Darker Mosley, by an instrument in writing under my
hand and seal, particularly to describe and ascertain the nature of my 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 recited
Letters Patent, as in and by the same, reference being thereunto had, will
more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Darker Mosley, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be performed, are
described and ascertained in and by the Drawings hereunto annexed, and the
following description thereof (that is to say) :-
My improvements in machines employed for the manufacture of lace, com-
monly called bobbin net, consists in the introduction of a certain combination
of parts (new, as applied to lace machinery), and by which different construc-
tions of machinery used for the manufacture of lace may be worked by a
rotary motion. This combination of parts is shewn in the Drawings adapted
to a lace machine constructed upon what is commonly called Lever's principle,
but the same contrivance is capable of being applied to lace machines of several
other constructions besides that shewn. Instead of actuating the machine by
means of levers moved by the hands and feet of the operator in front as usual,
I.either employ a winch attached to a horizontal shaft in front of the machine,
from whence, by means of pinions and toothed wheels, rotary motion is given
to other shafts and cranks, as will be further described, or I attach a rigger to
an axle connected with the machinery, over which a band is passed leading
from the rotary shaft of a steam engine, water wheel, or any other first mover.
Fig. 1 of the Drawings shews an end view of a machine on Lever's
principle, with my improvements attached.
Fig. 2 is a section of the same, supposed to be cut through the centre of
the machine in a perpendicular direction.
Fig. 3 is a detached part of the machine, shewing the mode by which the
point bars are brought down.
Fig. 4 is a plan or horizontal view principally of the new combinations,
designated to shew their connection to the old, the operating parts of the lace
machine being removed.
Fig 5 is a back view of the entire machine in which the new invented
combinations only are colored, the respective letters refering to the same parts
in each Figure.
Instead of working the machine by means of handles attached to the
front landing bar as usual, I place a horizontal shaft a in suitable bearings
connected to the woodwork or framing of the machine, and at one end of this
shaft I attach a winch or handle b,, and to the other end a toothed pinion c;
this pinion takes into a toothed wheel d, and the wheel d into another toothed
wheel e of equal diameter, which last is fixed upon the main shaft or axle f;
upon this shaft or axle f is also fixed a larger wheel g, four fifths of the
periphery of which wheel has teeth, and the other fifth is left blank; this

page_text: wheel is intended to take into a pinion h, on the crank shaft i, i, which pinion
is one fifth the diameter of the wheel h. To the crank shaft are also attached
jointed connecting rods k, k, which are affixed to that part of the lace machine
called the goose-necked lever, by which means the revolving of the shaft and
handle a &b causes the operative parts of the machine to be actuated. The
handle b, being uniformly turned by the operator, gives rotary motion to the
wheel g, as before said, the teeth of which wheel, taking into the pinion h,
causes that pinion and the crank shaft i to revolve four times during the
revolution of the toothed part of the wheel g, and hence by the connecting
rods k, k, four strokes are given to the goose-necked lever for the purpose of.
moving the operative parts of the machine exactly as when the front landing
bar is lifted four times by the handles, the ordinary mode of working the Lever's
machines. The crank shaft remains stationary, while the blank part of the
wheel g is passing the pinion in order to bring down the point bar (by a con-
trivance, which will be presently explained), and upon the end of the crank
shaft a disc is fixed with a notch in its edge, into which a pall drops in. order
to hold the crank shaft still during the descent of the point bar. At the
inner extremity of the shaft or axle f (about the middle of the machine) a
piuion is fixed, which revolves with the shaft f; this pinion takes into a toothed
wheel m of twice the diameter of the pinion, and which toothed wheel is
thereby made to turn once round to two revolutions of the main shaft f and
pinion ; upon this wheel m there are two tappets n, n, so adjusted that one
of these may raise one of the lifting rods o immediately as the crank shaft i
and its connections become quiescent. These lifting rods o are suspended by
pivots from the tail poles p, p, and as they rise respectively lift the tail poles and .
depress the point bars, which movements, in the ordinary Lever's machine, are
effected by the traddles at bottom. Hence, it will be seen that when, by the
revolution of the crank bar, as above described, the four strokes of the goose-
necked lever has been produced, one of the tappets immediately raise one of
the tail poles, and the driving up of the twist is effected. It is scarcely neces-
sary to say that every revolution of the main shaft carries the machine through
the several motions for the formation of one mash. I have thus far explained
my mode of working a Lever's lace-making machine by a rotary motion
actuated by hand, but the same may also be put in motion by the power of
steam, water, or other first mover. It will, however, in that case be desireable
to attach a rigger to the main shaft f, and to dispence with the horizontal
shaft a, the winch 6, the pinion c, and the toothed wheels d & e. The other
parts of the improvements will be similar in construction and action to those
above described, and the revolution of the main shaft with its connections will

page_text: effect the movements in other machines in the manner already explained.
Though I have only exhibited this my improvement attached to a machine
upon Lever's principle, yet I mean to claim the same contrivance as capable
of communicating motion to various other kinds of lace machine by a rotary
power, and in adapting this, my improvement, to such other machines I should
not alter the general construction of the parts which I have called new, as
applied to lace machines, but merely introduce such known modes of attach-
ment as may, under circumstances, be found desireable, varying of course
according to the particular construction and dimensions of the machine intended
to be so worked.
In witness whereof, I, the said William Darker Mosley, have hereunto
set my hand and seal, this Tenth day of September, in the year of
our Lord One thousand eight hundred and twenty-four.
