IMPROVEMENTS IN THE MODE OF TURNING THE WELTS OF KNITTED OR LOOPED FABRICS AND IN INSTRUMENTS TO BE EMPLOYED THEREFOR
Year: 1873

page_text: LETTERS PATENT to William Campion, of the Town and County of
the Town of Nottingham, Sewing Machine Manufacturer, and
William Campion, of Sneinton, in the County of Nottingham,
Mechanic, for the Invention of "IMPROVEMENTS IN THE MODE OF
TURNING THE WELTS OF KNITTED OR LOOPED FABRICS AND IN INSTRUMENTS
TO BE EMPLOYED THEREFOR."
Sealed the 8th April 1873, and dated the 12th February 1873.
PROVISIONAL SPECIFICATION left by the said William Campion
and William Campion at the Office of the Commissioners of
Patents, with their Petition, on the 12th February 1873.
We, WILLIAM CAMPION, of the Town and County of the Town of
Nottingham, Sewing Machine Manufacturer, and WILLIAM CAMPION,
of Sneinton, in the County of Nottingham, Mechanic, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE MODE
OF TURNING THE WELTS OF KNITTED OR LOOPED FABRICS AND IN INSTRUMENTS TO
BE EMPLOYED THEREFOR," to be as follows:-
Heretofore hooks having grooves on their backs have been employed
for the purpose of turning the welts of knitted fabrics, but these have

page_text: been somewhat difficult of use as it is necessary after the loops of the
slack course have been stroked on to the needles to turn the hooks
completely over to enable them to be released from the loops.
"
According to our improvements we obviate the necessity of turning
the instruments over after the loops of the slack course have been
stroked on to the needles, and simply slide the instruments endwise out
of such loops to release them. For this purpose we employ a bar of
instruments of the character of self-acting needles but having grooves on
their backs; these instruments are hung on to the "slack course as
heretofore, but when the loops have been stroked on to the needles
instead of turning the instruments over to release them from the loops
they are simply slided endwise away from the needles, when the
" tumblers are by the loops turned over on to the hooks, thereby
enabling such loops readily to slide off these instruments.
"
"
«
"
Instead however of employing instruments of the character of self-
acting needles a bar of instruments of a similar character to warp
guides" may be employed, such instruments having grooves on their
backs as before described. In this case we employ a wire in connection
with such instruments to pass through the eyes thereof. In using this
arrangement the bar of instruments with the wire previously passed
through the eyes thereof is hung on to the needles just previous to
a "slack course" being made. The "slack course is then "drawn
when the bar of instruments will hang from such course by the wire
aforesaid until a suitable number of courses are drawn to form the
"welt," when the grooves of the instruments are pressed on to the ends
of the needles, as before, and the loops stroked on to the needles; the wire
is then drawn out from the eyes of the instruments when the latter may
be liberated from the loops by simply sliding them outwards away from
the needles, as before described. By these means instead of having as
heretofore a bar of instruments to cach width of fabric being produced
in the machine, we are enabled to employ a single bar extending across
all the widths of fabric in the machine, thereby enabling us to stroke off
all the loops of the slack courses on to the needles at one operation, and
then to remove the bar of instruments simultaneously from all the
widths of fabric in the machine.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Campion and William Campion in the
Great Seal Patent Office on the 12th August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
CAMPION, of the Town and County of the Town of Nottingham, Sewing
Machine Manufacturer, and WILLIAM CAMPION, of Sneinton, in the
County of Nottingham, Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of February, in the
year of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said William Campion and William
Campion Her special license that we, the said William Campion and
William Campion, our executors, administrators, and assigns, or such
others as we, the said William Campion and William Campion our
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
"IMPROVEMENTS IN THE MODE OF TURNING THE WELTS OF KNITTED OR LOOPED
FABRICS AND IN INSTRUMENTS TO BE EMPLOYED THEREFOR," upon the condition
(amongst others) that we, the said William Campion and William
Campion, our exccutors or administrators, by an instrument in writing
under our, or their, hands and scals, or under the hand and scal of onc
of us or them, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Scal 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 William
Campion, 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 thereof, reference

page_text: being had to the Drawings hereunto annexed and to the figures and
letters marked thereon, that is to say :-
Heretofore bars of hooks having grooves on their backs have been
employed for the purpose of turning the welts of knitted fabrics, but
such hooks are somewhat difficult of use as, after the loops of the slack
.course held by such hooks have been "stroked" on to the needles, it is
necessary to turn the hooks completely over to enable them to be
released from the loops, besides which when employing such description
of hooks it is necessary to employ a separate bar of them to each width
of work in the machine.
According to our improvements we obviate the necessity of turning the
instruments over after the loops of the slack course have been stroked on
to the needles and simply slide the instruments endwise out of such
loops. For this purpose, according to one arrangement, we employ a
bar of instruments of the character of self-acting needles but having
grooves on their backs, as shown at Figures 1 and 2 of the accompanying
Drawings, which represent respectively a back view and an end view of
a portion of a bar of such instruments. These instruments are hung by
their hooks a on to the slack course as heretofore, and after the desired
number of courses have been made to produce the welt the bar of
instruments is held against the needles in such manner that the ends of
the needles enter the grooves a² of the instruments and the loops are
then stroked on to the needles as is well understood, but when the loops
have been stroked on to the needles instead of turning the instruments
over as heretofore to release them from the loops, the improved
instruments are simply slided endwise away from the needles when the
" tumblers a² are by the loops turned over on to the hooks, thereby
enabling such loops readily to slide off these instruments.
"
Instead however of employing instruments of the character of self-
acting needles, as before described with respect to Figures 1 and 2 of the
accompanying Drawings, a bar of instruments of a similar character to
warp guides" may be employed, such instruments having grooves on
their backs as before described.
"

page_text: such as those herein shown and described for turning the welts of
knitted or looped fabrics in manner substantially as herein described.
In witness whereof, we, the said William Campion and William
Campion, have hereunto set our hands and scals, this Ninth
day of August, in the year of our Lord One thousand eight
hundred and seventy-three.
