page_text: PROVISIONAL SPECIFICATION left by James Collier, Ralph Howarth,
and William Cryer at the Office of the Commissioners of Patents, with
their Petition, on the 8th June 1867.
We, JAMES COLLIER, Foreman, RALPH HOWABTE, Machinist, and WILLIAM
CRYER, Machinist, all of Bolton-le-Moors, in the County of Lancaster, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR KNITTING HEALDS,"" to be as follows:-
Our Invention relates to the "healds" or harness used in looms for
weaving, and consists in a novel method of forming two or more "healds" or
eyes simultaneously, whereby a saving is effected in the time usually required
to make a complete set of healds.
Our improved method being as follows, namely:-A number of bobbins of
yarn corresponding to the number of healds which it is desired shall be
knitted at once are suitably arranged at the back of the machine, and the ends
of yarn from the said bobbins are drawn through guides to bring the said ends
into positions parallel and equidistant one with another. A bar furnished
with a number of "clips" or pairs of fingers capable of being opened and
closed by a sliding or other suitable movement is then brought over the ends
of yarn, each of the said ends of yarn entering between a pair of the fingers,
so that when all the fingers are closed a firm hold of all the ends is obtained ;.
the bar is then moved towards the centre of the machine into a position under.
or near the rod upon which the "eyes" of the "healds" are formed. A second
bar similar to the first one above described is then brought into position and

page_text: caused to take hold of the ends of yarn upon which the first bar is released
and moved away. By means of the second bar the ends of yarn are now
drawn over the eye "rod" and a suitable quantity of yarn is drawn from the
bobbins to form the plain or unknitted looped portions of the bealds, which
are then severed from the supply of yarn, and the free ends of the loops are
cemented or otherwise suitably fastened to a heald shaft. To form the eyes
the ends of yarn are seized by the first bar, as above described, and passed
through the spaces in a row of pins and through the loops first formed, as
above described, and under the eye rod, whence they are taken by the second
bar, drawn over the said eye rod, and brought back to the row of pins above
mentioned, each end of yarn coming from the eye rod being passed around
the back of one of the pins and over and below the yarn passing to the "eye
rod, so that a loop is formed with the pin inside or between the two yarns,
constituting the said loop; the other bar is now brought into a position that
will allow all the clips to pass through the said loops and to take hold of the
ends of yarn, which are now drawn through the loops, by which means a
single "tie" is formed, which is drawn to, the "eye rod;" a double "tie"
"knot" being formed by a repetition of the single. "tie;" the yarn is now severed
and the free ends attached to a second "heald shaft." To attach the ends of
yarn firmly we sometimes make the heald shaft in two pieces, and glue or
cement the same together with the ends of yarn between the connected
surfaces.
