the reign of His late Majesty King William the Fourth, intituled "An
"Act to amend the Law touching Letters Patent for Inventions," and
of another Act passed in the Session of Parliament held in the seventh
and eighth years of the reign of Her present Majesty Queen Victoria,
intituled "An Act for amending an Act passed in the fourth year of the
"reign of His late Majesty, intituled An Act for the better Adminis-
"tration of Justice in His Majesty's Privy Council, and to extend its
"Jurisdiction and Powers," by CHARLES WARWICK, of Cheapside, in
the City of London, Merchant, and JOHN SMITH, formerly of Alderman-
bury, in the said City, but now of Cheapside aforesaid, Woollen and!
Manchester Warehouseman, assignees of the said Letters Patent, and of
the whole interest therein, the said John Anthony Tielens having duly

page_text: departed with the whole interest in such Letters Patent to the said
Charles Warwick and John Smith, by an assignment duly made and
executed by him on the Ninth day of April, One thousand eight hundred
and forty-five.
Since the inrolment of the said Specification it has been discovered by the
said John Anthony Tielens that in the Specification of a Patent granted to
Mark Isambard Brunel on the Fourteenth day of March, One thousand eight
hundrod and sixteen, a machine is described for producing kuit fabrics, in
which needles are fixed radially round a circular plate, the loops being formed
on the needles and removed therefrom by certain rotating instruments therein
shewn and described, and with which Patent and Specification the said John
Anthony Tielens was not nequainted at the time of onrolling his said Speci-
fication, for which reason we wish to disclaim and do hereby disclaim so much
of the said Specification of the said John Anthony Tielens as consists of the
second claim therein made; that is to say, we do disclaim and striko out of
the said Specification the following words:-"Socondly, I claim the arrange-
"ment and combination, herein-beforo described, of the needles placed
radially round a circular plate or dise, and the application of such apparatus
"for the production of knittod or looped fabrics." And in order that the
first claim in the said Specification may not bo considered to claim all the
means of operating described and shewn, we alter and limit the first claiming
clause in the said Specification by adding thereto the following words, vide-
licet, "on needles fixed radially round a circular plate, such radial position of
the neeilles not being claimed as new, after the word "work" in the said first
claiming clauso.

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
ANTHONY TIELENS, of Fenchurch Street, in the City of London, Merchant,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Seventh day of April, in the fifth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
John Anthony Ticlens, Her especial licence, full power, sole privilege and
authority, that I, the said John Anthony Tielens, my executors, admini-
strators, and assigns, and such others as I, the said John Anthony Tielens, my
executors, administrators, or assigns, should at any time agree with, and no
others, from time to time and at all times during the term of years therein
mentioned, should and lawfully might make, use, exercise, and vend, within
England, Wales, the Town of Berwick-upon-Tweed, and in all Her Majesty's
Colonics and Plantations abroad, and in the Islands of Jersey, Guernsey,
Alderney, Sark, and Man, an Invention of "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR KNITTING," being a communication from a foreigner residing
abroad; in which said Letters Patent is contained a proviso, obliging me, the
said John Anthony Tielens, by an instrument in writing under my hand and
seal, particularly to describo and ascertain the nature of the said Invention, and
in what manner the same is to be performed, and to cause the same to be
inrolled in Her Majesty's High Court of Chancery within six calendar months
next and immediately after the date of the said in part recited Letters Patent,

page_text: as in and by the same, reference being thereunto had, will more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, 1, the said
John Anthony Tielens, do hereby declare the nature of the said Invention,
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, and the Drawings therein
referred to (that is to say):-
The said Invention of certain improvements in machinery or apparatus for
knitting consists in the construction and employment of certain apparatus, and
the arrangements thereof, in conjunction with suitable mechanism, as hereafter
described, for producing loops or meshes, which, being continued, form tho
knitted work or fabric. And in order that the Invention may be perfectly
understood, I have shown in the accompanying Drawings various views of
the machine, and some of its parts detached, in which its construction and
operation is distinctly shewn. Fig. 1 is a side elevation of the whole machino
complete; and Fig. 2 is a vertical section, taken through the middle of the
same; Fig. 3 represents a plan or horizontal view of Fig. 1; and Fig 4 is a
horizontal section or sectional plan, taken through the line A, B, of Figures
1 and 2. The machine, which is of a circular form, is suspended from the roof
or from a strong beam by means of the vertical shaft or axle a, a, and is com-
posed principally of the four following parts, to which the minor portions of
the machine are connected. These four principal parts consist of four plates
b, c, d, and e, seen best in the sectional view, Fig. 2. The first plate b, b, is firmly
secured to the vertical shaft a, a, in any convenient manner, and is intended
to support various stationary parts of the apparatus that act upon the needles
and jacks or sinkers, as will be hereafter described, and is thereforo de-
nominated the "support plate." The second plate c, c, is called the "needlo
plate," because the needles are ranged radially round its circumferance, as
seen in the sectional plan view, Fig. 4, and also in the detached Figures.
This plate is mounted loosely on the vertical shaft a, a, and revolves freely
around it, and is connected with the third plato d, d, by means of the bolts
and nuts ff (see Fig. 2). This plate d, d, which is made in the form of a
broad ring, is furnished at or near its periphery with long slits or openings
(sce attached view, Fig. 5), which receive the jacks or sinkers, and maintain
them in a perpendicular position. From the circumstance of this plate being
thus perforated with long slits or openings, it is called the "comb plate." The.
fourth plate is shown at e, e, and is firmly fixed to the vertical shaft a by
screws or otherwise, but is capable of being raised up and down, and at its
height thereby regulated (when required) by means of the screw box 9 below

page_text: (as seen in Figures 1 and 2), and the helical spring (seen in Fig. 2), the
position of the railway plate requiring adjustment according to the fineness
and coarseness of the thread, and the clasticity which the knitted fabric is to
possess. The plate e, e, is called the "railway plate," because an undulating
rib or rail, which is formed on its upper surface, supports the lower ends of the
jacks or sinkers h, h, and by means of the undulations formed thereon, which
in the machine as represented are four in number, the action of the sinkers,
as seen in Fig. 1 and Fig. 6, is regulated. From the foregoing it will be
understood that the top and bottom plate 6 and e, or, as they may be called,
the "support plate" and "railway plate," are stationary, being fixed to the
vertical shaft a, a, as before stated, and that the "needle plate" c and "comb
plate" d, which are connected together by the bolts f, f, revolve freely round
the shaft a, a; rotary motion is communicated to them by means of the
bevil pinion i, i, on the crank shaft, which pinion gears into a circular bevil
rack j,j, formed on or attached to the upper face of the needle plate c, c, (as
seen in Figures 2 and 4.) As these plates revolve and carry round with them
the needles k, k, and sinkers h, h, these latter are made to fall and rise in the
perforations of the comb plate and between the needles of the needle plate,
according to the undulations formed on the upper surface of the railway plate;
but as these sinkers might not always descend by their own weight at the proper
time, they are made to do so by coming into contact with and passing under
the inclined end of the metal piece 7, 1, (see Figures 1, 2, and 6). When the
sinkers have passed down (as shown in Fig. 6) the inclined plane of the
railway plate, they are kept down by the angle piece e', Figures 1 and 7,
which catches on a ledge on the front part of the sinker, as seen in Fig. 7;
the requisite outward motion of the sinkers between the needles to form
the loop is effected by the cam pieces m, m, and n, n, which are supported
from the plate b, b, above, as seen in the Figures. When the sinkers
have passed in front of these cams, they are forced back into their original
positions by the helical spring o (as seen in Figures 1, 2, and 6), which sur-
rounds them, and also by the pressing pieces p and p" (as seen in Figures
4 and 6). The cam pieces n, n, are mounted on centres at 9 (Figures 3
and 4), and the distance that the sinkers are forced out by them is regulated
by means of the screw r, which passes through a block on the same, and abuts
against a stationary pieces (seen best in Figures 3 and 4). The motions of
the sinkers, it therefore appears, are regulated as follows:-The upward and
downward or vertical motion in the comb plate by the undulations on the
railway plate; and the outward motions between the needles of the needle plate
by the cams m and n; the backward motion by the spring o and pressing.

page_text: P
pieces and p. The threads (of which they are four in this machine) to
form the work enter by the trumpets t, t, (Figures 2 and 4), and aro conducted
by them under the front notches h*, *, *, of the sinkers h, h, h, (Fig. 2,) and.
Inid along the needles (as seen in Fig. 4). The front notch of the sinker.
having taken hold of the thread during the descent of the sinker between the..
needles down the inclined plane in the railway plate, a loop hanging down
between the needles is formed, and at the same time the sinker is pressed.
forward between the needles by coming into contact with the cam m, and:
thereby the loop is carried under the beak or beard of the neeilles, as shewn,
at Fig. 7. It will be observed in Fig. 6, that after the sinkers have descended.
the inclined plane of the railway, as already described, and before they begin,
to ascend the opposite incline, as hereafter described, they pass along a hori
zontal portion, which is represented in the Drawing, Fig. 6, as capable of being.
adjusted by a screw; this, however, it not essential to the machine, the adjust-
ment of the sinkers as to height, if the machine is accurately constructed, being
made by the screw box g, as above described. When the lower end of the
sinker comes into contact with the opposite incline (see Fig. 1 and Fig. 6) it.
is raised, and is also pressed back by the pressing piece p*, which forces back.
the work and the sinker into the recess between the two cams m and n (ns
shewn by dots in Fig. 5); the effect of this will be, that as the sinker h passes
up the inclined plane on the railway plate the notch of the sinker will be
raised out of the loop, and as the sinker is pressed back by the piece p*;
the point 1, Fig. 7, catches hold of the work and draws it back from under
and beyond the beak or beard of the needle, which is then closed by coming
under the revolving presser plate or roller (as seen in Fig. 11); then
the sinker in continuing its progress is brought against the cam n, n, which
gradually forces it outward, and by the projecting shape of its breast pushes.
the work over the beard of the needle, which has been closed for this purpose
by the presser plate u, and ultimately throws the loop of the work already
mado over the end of the needle, and thereby over the loop which has
just been made, as seen in Fig. 12, and C, Fig. 5, and which loop remains
at the end of the needle until another loop is made by the next two needles;
When the work is thrown over it is pressed back by the notched wheel w,
and the sinkers aro brought into their original position by the spring o
already mentioned. The construction of the needles, and the manner of
fixing and securing them in the needle plate, so that they can be changed or
removed at pleasure, is distinctly shown in Figures 8, 9, and 10., The inner
end of the needle is bent down and enters a circular groove, made by scrowing
a brass ring on to the needle plate near its periphery. The shafts of the

page_text: needles lie radially round the needle plate in grooves or notches made on the
upper side of the brass ring y, as seen in Fig. 8, and the needles are firmly
secured in their proper places by means of the sector pieces, which are
screwed tightly down to the needle plate. A ring of leather, felt, pasteboard,
or other suitable substance, is placed between the sector pieces z and tho
needles, and thereby holds the needles more firmly.
Having, now described the Invention that has been communicated to me,
and the manner of carrying the same into effect, it is scarcely necessary to
point out to any one acquainted with the construction of machines that the
form and construction of this machine admits of considerable variation, and
many of the operations may be performed by other mechanical devices. I
therefore do not confine myself to the precise arrangement and construction of
parts herein shewn, nor do I claim the exclusive use of any of the several
parts, except as herein-after mentioned, unless the said several parts be used
in the construction and working of a machine, as herein-before described, for
producing knitted work or fabrics; but I claim, as the Invention secured to
me by the herein-before in part recited Letters Patent,-
Firstly, the peculiar arrangement of mechanism, or combination of parts,
herein-before described, for performing the operation of knitting or producing
looped work.
Secondly, I claim the arrangement and combination, herein-before described,
of the needles placed radially round a circular plate or disc, and the application
of such apparatus, for the production of knitted or looped fabrics.
Thirdly, I claim tho peculiar construction and combination of the comb plate,
railway plate, and sinkers, and the application thereof, for the production of
knitted or looped fabrics, as herein-before described.
Fourthly, I claim the peculiar combination and arrangement of the circular
disc and wheel, as herein-before described, for closing the beak of the needles
and pressing back the work in the process of knitting.
Lastly, I claim the peculiar construction, combination, and arrangements,
berein-before described, for fixing and removing the needles employed in
knitting by machinery.
In witness whereof, I, the said John Anthony Tielens, have hereunto set
my hand and seal, this Fifth day of October, in the year of our Lord
One thousand eight hundred and forty-two.
