PROVISIONAL SPECIFICATION left by the said Willian Campion.and
Henry Johnson at the Office of the Commissioners of Patents, with
their Petition, on the 2nd September 1861.
We, WILLIAM CAMPION and. HENRY JOHNSON, both of the Town and
County of the Town of Nottingham, Sewing and Stitching Machine
Manufacturers, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR CUTTING THE SELVEDGES OR
EDGES OF KNITTED OR OTHER FABRICS WHILE BEING STITCHED," to be as follows:-
Our Invention has for its object saving of time, labour,and expense in cutting
the selvedges or edges of knitted or other fabrics. This operation has hitherto
been performed by hand labour, which is a slow process, occupying much
time and attended with expense; whereas by our Invention much of the
labour, time, and expense heretofore required are dispensed with. Our
improvements consist of the machinery or apparatus of a pair of cutters of
Price Sal

page_text: suitable construction; these cutters we employ in an ordinary sewing or
stitching machine, by means of which wo cut the selvedges or edges of knitted
or other fabrics while they are being stitched, and at the same time we lay
down the selvedges smoothly. Our invention is also applicable to sewing or
stitching machines heretofore in use.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed

and ascertain the inture of the said Invention, and in what manner the
same was to be performed, 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 we, the said William Campion and Henry
Johusou, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and ascer
tained in and by the following statement thereof, reference being had to the

page_text: accompanying Drawings, and to the letters and figuresmarked thereon, that
is to say
:
. ti..
Our Invention has for its object the saving of time; labour, and expense in
cutting the selvages or edges of knitted or other fabrics. This operation of
cutting the selvages or edges of knitted or other fabrics has hitherto been
performed by hand labour, which is a slow process, occupying much time
and attended with expence ; whereas by this our Invention the labour, time,
and expense heretofore required are dispensed with, and consequently much
saving is effected... Our improvements consist of machinery or apparatus in
which is a pair of cutters of suitable construction, applied to or combined
with an ordinary sewing or stitching machine, by means of, which we cut the
selvages or edges of knitted or other fabrics while they are being stitched, and
at the same time we lay down the selvages smoothly..
Our Invention is also applicable to sewing or stitching machines heretofore
in use.
Having thus stated the nature of our Invention, we now proceed to describe
the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1, Sheet I., is a plan of an ordinary sewing machine (used for
stitching knitted or other fabrics) having our cutting apparatus attached for
cutting off the edges, or selvages after the fabric has been stitched.
A is the arm of the ordinary sewing machine, in which the pin.B, of the
wheel C is held fast by a set screw; the wheel C is turned true on its
circumference, on which a ring D, made of brass or other suitable metal, is
free to turn. This ring is provided with teeth E round the whole of its
upper edge, and its circumference is furnished with points F, upon which
the fabric to be stitched is placed, the ring being moved round the length
of a stitch by the small wheel G in the usual way. The ring D differs
from the ordinary ring in having a second set of teeth E, these teeth gear
into the teeth of a pinion H on the upper end of a short shaft passed through
one of the arms of the wheel. C; on the lower end of the shaft under
the arm is another toothed pinion I, (not shewn in Figure 1, but is seen in.
section, Figure 2, Sheet 2,) which takes into the teeth on the inside of the
rim of a wheel K; which is in addition to the wheel C, and turns upon a
pin or axle screwed in the wheel C; the wheel K is also furnished with
points, and being of less diameter than the wheel C, the points of each
wheel will be together only at that part where the two circumferences
stand over each other. There is a portion cut out of the rim of the wheel C,

page_text: and in place of such portion so cut away the upper half of the cutting
instrument L is secured to the wheel Crby screws; the other or lower half
of the cutting instrument L is held firmly to the upper by a pin, and by
lock nuts, and the end opposite to the pin in the lower cutter is slotted
to receive a pin in one end of a bolt M, which has a to-and-fro movement
given it by means of an excentric N on the usual cam shaft O.of the stitching
machine, thus the edge of the fabric which has been stitched will be
cut off as fast as it is stitched, the fabric being held up by the points in
the lower wheel K, and tho waste edges or selvages being on the points F
in the upper wheel D. The above exemplifies our improved apparatus
for cutting the edges or selvages off after and during the time the fabric is
being stitched.
Figure 2, Sheet 2, represents the wheels O and K, and the ring D,
and the pinions H and I in section as cut through the several centres
of each of them. Figures 3 and 4, Sheet 2, represent the lower and
upper blades of the cutting apparatus. The several corresponding parts
are lettered alike in each Figure. For cutting the edges. or selvages
of a fabric before the same is stitched, and during its being stitched, we use
the following apparatus, shewn in plan at Figure 5, Sheet 2:-Instead of
the ordinary arm A, we use an arm A', secured to the bed plate of an
ordinary stitching machine; one end of the arm has a bosa cast on the under
side, into which a pin is screwed, which holds fast a wheel K!, having its
rim turned true to carry a double rimmed ring Ka, the inner rim of which
is provided with teeth on the whole of its upper edge; the outer rim is
provided with points, upon which the fabric to be stitched is placed, the
ring K being moved round the length of a stitch by a clawker P, which
works upon and is moved by a pin secured on the ordinary needle bolt, or an
additional bolt lying parallel to the needle bolt, and moved by a link and
pin in a toothed wheel gearing into another wheel on the cam shaft, the
ring being moved round on the withdrawal of the needle, the clawker moving
the ratchet wheel Q, working on an axle in the boss on the arm A¹ the
pipe of the wheel Q is cut at the end to form a pinion Q, which gears into
the teeth on the inner rim of the ring K. To one arm of the wheel K¹ is
secured a bracket R, which forms one half of a pair of guides, the other
half Ris also: secured to the bracket. The fabric as it is carried round
by the points passes between the guides, and as it passes out the edge or
selvage is cut off by the pair of cutting instruments L₁, the upper half of
which is secured to an adjustable bracket S, secured to another bracket S¹
attached to the bed plate of the stitching machine. The cutters can be

page_text: adjusted to cut off the edges or selvages of the fabric at any required height
above the top of the outer rim of the ring K². The two halves of the
cutting instrument are shewn separately at Figures 9 and 10, Sheet 2;
the lower half, shewn at Figure 9, has the end opposite the cutting end
bent down, and has a slot cut in it through which a pin or screw is passed
into the ordinary needle bolt, the cutters cutting off a portion of the fabric
at each stitch made. The edge of the fabric after leaving the cutters passes
into a second pair of guides Tand T₁, the part T¹ being screwed to the under
side of the arm A¹ during the passage of the fabric between the guides T
and T the fabric is stitched, the needle entering the fabric just above the
outer rim of the ring K2, a portion being cut out of the guides Tand T¹ for
the passage of the needle, as shewn in the side view of the guides, Figure 7,
Sheet 2. Figure 8, Sheet 2, is a side view of the guides Raud R. Figure 6,
Sheet 2, represents the wheel K¹ and the ring K2 in section. The above-
described apparatus shewn in the Figures represents our two methods of
cutting off the edges or selvages of fabrics both before and after the same
are stitched and during the time the same are being stitched.
Having now described the nature of our said Invention and in what
manner the same may be performed, we declare that we claim, the arrange-
ment and combination of machinery or apparatus for cutting the selvages or
edges of fabrics while being stitched.
In witness whereof, we, the said William Campion and Henry Johnson,
have hereunto set our hands and seals, this Twenty-seventh day of
February, in the year of our Lord One thousand eight hundred and
sixty-two.
