One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Campion, Her special licence that I, the said William
Campion,.my.executors, administrators, and assigns, or such others as I, the
said William Campion, 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 "IM-
PROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF LOOPED FABRICS," upon
the condition (amongst others) that I, the said William Campion, my
executors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, 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 William Campion, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, 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 improvements in machinery for the manufacture of
Jooped fabrics which are obtained by the arrangement and combination of a
moveable needle bar and needle presser, and looped hooks and sinkers and
thread carriers, which are moved by cams, by which arrangement and com-
bination I obtain a greater speed, and consequently can perform more work
in a given time than has been hitherto produced from this description of

page_text: machinery. I may state that I propose to apply what is called a narrowing
apparatus to this my Invention.
I now proceed to explain my Invention more particularly with reference to
the accompanying Drawings.
The first part of my Invention refers to the producing of a plain looped fabric
of any required width. Figure 1, Sheet 1, represents a front view of the
machine with parts of the several bars, &c. broken away to shew more fully
the arrangement of the same. Figure 2, Sheet 2, is a right-hand end view of
the same, partly in section. Figure 3, Sheet 3, is a front view, shewing the
arrangement of certain parts of the machine used when a slack course is
required to be made. Figure 4, Sheet 8, is a plan of the double-arched lever
and chains attached to the carrier slide bolt and truck bar, and the cam
which moves the same. Figure 5, Sheet 3, represents the comb bar, comb
jack, sinkers' needle bar and needle, presser hook and wire presser, the slur
cock bar to lower the sinkers, and the tappet slide bar to raise them up, and
the two bars which answer the top bar as a falling bar, and the bottom bar as
a régulating bar, in their several relative positions. Figure 6, Sheet 3, repre-
sents cams No. 1, No. 2, No. 3, in their relative positions when the thread is
being laid upon the needles; and Figure 7, Sheet 3, represents the drawing
or carrier cam. The full size cam No. 1 gives motion to the presser hooks;
cam No. 2 gives motion to the needle bar; cam No. 8 gives motion to the
falling bar and regulating bar; cam No. 4 gives motion to the double-arched
lever, which moves the slur cock slide, carrier slide, and tappet slide. All the
corresponding parts in each Figure are lettered alike.
DESCRIPTION OF PARTS OF THE MACHINE AND THEIR SEVERAL SEPARATE
MOVEMENTS.
-a, a, (Figures 1 and 2, Sheets 1 and 2,) represent the end castings which
carry. tie bars b, c, d; e is a back stay screwed to the tie bars b, c. To the
standards a and stay e are screwed bearings carrying the cam shaft f, the
needle bar lever shaft 9, the presser hook lever shaft h, and a shaft i, which carries
the brackets, to which the falling and regulating bars are screwed. At each
end of the machine is screwed a bracket j, which brackets support a bar k,
extending the length of the machine; this bar has a V groove in its upper and
lower edge, in which the thread carrier slide bar is free to slide longitudinally
by means of four brackets . At each end of the slide bar is a bracket, in
which the carrier bolt is free to slide to the right or left; the thread carriers, to
which a piece of fur is tied near the lower end in the usual way, being screwed

page_text: to the slide bar l, moved to the right or left by the cam No. 4 revolving
between the two trucks attached to the truck bar m. Two chains are attached
to the truck bar by one end; the other ends are attached to either end of the
smaller arc of the lever n; and two other chains are attached to the larger
are and to two brackets attached to the slide bolt ; each chain at the end
that joins the slide bolt or truck bar is furnished with a screw pin and nuts
which act as set screws. To the slide bolt is also screwed a driver *; in the
back end of this driver is a hole to receive a pin screwed to the tappit slide
bar ; this bar is free to slide the length required in arched brackets screwed
to the back of the comb bar q. To the bar are screwed the tappit plates 1º,
which lock up the jack sinkers; the tappet slide having the same length of
right and left motion as the carrier slide bolt P. The bracket to the right
of the frame has a projection at the back, the use of which is to be explained
herein-after. When the slide bolt has arrived near the end of its right or
left hand motion, the inclined ends will be driven against the knock-outs,
which will lift either end up, thus leaving the thread carriers stationary when
they have laid the length of thread required, and allowing the slur cocks and
tappets to pass clear of the jack sinkers before returning for another course.
To the back of the tappet plates is screwed a stopping bar ³, which prevents
the tails of the jacks from being knocked up above a certain height; o is the
needle bar on which the needle leads are securely held by plates and screws, as
shown, the bar being screwed to arms o¹ working on pins in the upper ends
of the levers o³, held fast by set screws in the shaft g; on this shaft is another
lever o³, also held by set screws, the truck on this lever working on the cam
No, 2, which causes the needle bar to move backward and forward, it being
moved forward again by the spring o'. The needle bar is also supported by
a truck at each end (the truck axles are screwed to the end casting a); the
bar is supported in the centre by a set screw bearing upon the front of the
cap to the centre bearing of the shaft h; p is the presser hook bar, to which
are screwed the presser hook leads, the hooks having a hole in the upper part,
through which is passed a wire to press the needle beards as the needles are
'drawn back under it. The presser bar p is screwed to the arms p¹ fast on the
shaft h; the presser hook bar has a rising and falling motion imparted to it
by means of the truck on the lever p" working on the cam No. 1, which
communicates the requisite up-and-down motion; q is the comb bar, to which
the jack combs q' are screwed, carrying the jacks ; the comb bar is the same
length as the bar k, and is secured to the back of the brackets j. In front
of the bar q the slur cock bar q³ is held by five screws passing through it to

page_text: the bar q. The holes in the slur cock bar are slotted to allow of its being
depressed when a slack course is to be made, and it is set the required height
by means of a star screw and spring 9' at each end of the frame. A slack
course being required, the stop is lifted up from between the screw and
stop on the bar q³, the handle q being then moved to the left will cause the
bar 2 to be slightly lowered by means of the link shewn by dotted lines in
Figure 3 connecting the handle and the bar together, the handle turning on
pin in a bracket on the shaft i. There are three other brackets v, to
which are attached short links which work on pins the same height as the
pin on which the handle o turns. Near the lower ends of the links and
handle are screw pins which carry the falling bar v³, the falling bar being
raised when the bar q³ is lowered, when a slack course is being made. To the
brackets is also screwed the regulating bar v³%; the bars v' and have a
vertical motion given them by the truck on the lever v³ working on the cam
No. 3. The bar q³ has a groove in the front face, and is embraced by four
clips, which are portions of the slur cock slide bar, to which the slur cocks q*
are screwed; to one of these clips or saddles is screwed an arm q', to which
is fastened the driving plate q, furnished with two projections in the front,
between which the projection at the back of the bracket / lies, thereby allowing
the carrier needles and tappit plates to get in advance of the slur cocks on
the return course; W is a spring on the handle q, which spring bears upon
a notched arm W screwed to the regulating bar ³, the spring holding the
arm where placed; and sometimes instead of using the arm and plate q" and g
to drive the slur cock bar q³, I prefer using the arched driver R screwed to
the back of the carrier bolt, and lying between two stops in a plate S_screwed
to two of the clips 2*, as shewn in Sheet 8. The above is a full description of
the several parts of the machine as combined for producing a plain looped
fabric of any required width.
DESCRIPTION OF MOVEMENTS COLLECTIVELY ACCORDING TO THE ABOVE
COMBINATION.
:
In the Drawings the machine is represented as having made nearly half a
course to the right hand, the tappit plates having the lead, the thread carriers
follow and lay the thread on the needles, the slur cocks then follow and draw
the jacks, thereby sinking the loops, the regulating bar rising the height
required, and holding the loops firm until they have come under the cramp of
the needles' beards, the jacks are then raised by the falling bar being lowered
by the same cam No. 8; as the needles recede, the beards are. pressed by the

page_text: wire in the presser hooks moved by cam No. 1; the presser hooks then rise to
allow the loops to pass under the arch of the hooks, the breast of the hooks
knocking the work over by the needles being drawn further back by the cam
No. 2; the hooks then fall down with the work under the arch and the
needles are brought forward for a fresh course, which movements being
repeated will produce a plain looped fabric.
For producing a ribbed looped fabric the following additional parts are
required to be employed in combination with the before described parts, and
Figure 8, Sheet 4, is a sectional view of these additional parts so required;
Figure 9 is a top view of the frame needle; Figure 10, front view of the
machine needle; Figure 11, front view of a lead of hooks and presser wire;
Figure 12, comb and jack sinker axle; Figure 13, the sley T; Figure 14, a
portion of the presser U, shewing part of one of the arms screwed to the
presser bar p; and Figure 15, front view of portion of the slide X and pin X'.
Figure 8 to 15 are on a larger scale than Figure 1 to 5. These additional
parts represented in Sheet 4, Figure 8, consist of a sley T (to knock over
.the work during the production of the welt) screwed to the bar P₁ instead of
the presser hooks and wire p³. A presser bar U, supported by arms U¹, one
between every two divisions of work, screwed to and having the same move-
nient as the presser bar p. A machine needle bar W, which carries the
machine needle leads W¹, secured as shewn by plates in front of the bar W,
being held by arms Ws working on an axle passed through the levers w³,
which are held by set screws fast on a shaft placed in front of and a little
above the shaft g, the shaft carrying an arm and truck working on a cam on
the cam shaft, by which means the machine needle bar W is raised and lowered,
and to the axle of the lever W is secured a lever which also carries a truck
working on a cam on the cam shaft, which throws the machine needles forward
and takes them back for the purpose of pressing the machine needles; and
a slide X, supported by pins X, resting upon levers X2, held fast on a shaft X³,
lying in front of and above the shaft carrying the levers w. On the shaft X³ is
a lever carrying a truck working on a cam on the cam shaft, which raises and
lowers the slide ✗, as required for knocking over the frame course and
machine course together.
:
DESCRIPTION OF MOVEMENTS COLLECTIVELY.
The thread being laid the inck sinkers form the loon: while they are down

page_text: being completed, when it is knocked over at the same time as the machine
course, the machine needles being brought down until the machine
is pressed, when it is lowered a little more, and the machine course and frame
course are knocked over together; the above movements being repeated, a
ribbed looped fabric, will be produced.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that what I claim as my
improvements in machinery for the manufacture of looped fabrics is the
arrangement and combination of machinery constructed in the manner
herein-before described and exemplified in the accompanying Drawings.
In witness whereof, I, the said William Campion, have hereunto set my
hand and seal, this Fifth day of October, in the year of our Lord One
thousand eight hundred and fifty-nine.
