IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1879

page_text: LETTERS PATENT to James Rollinson, of Dewsbury, in the County of York,
Power Loom Tuner, and John Senior, of Dewsbury aforesaid, Power Loom
Tuner, for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING.”
PROVISIONAL SPECIFICATION left by the said James Rollinson and John
Senior at the Office of the Commissioners of Patents on the 15th April 1879.
JAMES ROLLINSON, of Dewsbury, in the County of York, Power Loom Tuner,
and JOHN SENIOR, of Dewsbury aforesaid, Power Loom Tuner. "IMPROVEMENTS IN
LOOMS FOR WEAVING."
This Invention has for its object an improved construction of needle, providing
self adjustment to compensate for wear of slot and of the jack blade or hook, so as
to prevent the jack falling, and faulty and imperfect pieces being produced. We
construct the needles of two parts, forming a recess in each of the separate
parts for the reception of the jack, blade, or hook; a spiral or other spring is applied
to one of the parts of the needle, so as at all times to keep the needle and jack in
close contact; a packing piece may be applied to either of the recesses when much
worn, whereby the needle becomes as new.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said James Rollinson and John Senior in the Great Seal Patent Office
on the 14th October 1879.

This Invention has for its object an improved construction of needle, providing
self adjustment to compensate for wear of slot, and of the jack blade or hook, so
as to prevent the jack falling, and faulty and imperfect pieces being produced.

page_text: We construct the needles of two parts, forming a recess in each of the separate
parts for the reception of the jack blade or hook; a spiral or other spring is applied to
one of the parts of the needle, so as at all times to keep the needle and jack in close
contact; a packing piece may be applied to either of the recesses when much worn,
whereby the needle becomes as new.
Such being the nature and object of this our said Invention, we proceed to describe
the particulars thereof, and in order that the Invention may be fully understood we
have hereunto annexed 2 Sheets of Drawings illustrative thereof, and have marked
the several parts with numbers or figures of reference, the same part being denoted
by like numbers in the several views. *
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a plan view of grate, needles, and jack blades or hooks in position;
Fig. 2 is an elevation of the same; Fig. 3 is an elevation of needle constructed
according to this our Invention detached; Fig. 4 is a plan view of the same; Fig.
5, a detail. At 1 is the head half or part of the needle; 2 is the other or corre-
sponding part; in each part is a recess 3, within which the jack blade or hook 4
works as ordinary; at 5 is a spiral spring on the spindle of part 2 of needle, which
spring serves to keep the parts 1, 2, forming each needle in position, in relation to
its jack blade or hook, and so compensates for wear of the slots. When either of
the recesses 3 become worn and enlarged, a packing piece 6 may be fitted within the
recess or recesses, as shewn at 6.
Having thus fully described the nature and particulars of this our said Invention,
together with the manner in which the same is to be or may be performed or carried
into practical effect, we would have it understood that what we claim as our
Invention is,―
Firstly. We claim the construction and use of needles for purpose herein described,
composed of parts 1 and 2, as illustrated.
Secondly. The construction, application, and use of needles, comprising parts 1,
2, and 5 combined, and as illustrated and described for purpose set forth.
In witness whereof, we, the said James Rollinson and John Senior, have
hereunto set our hands and seals, this Tenth day of October, in the year
of our Lord One thousand eight hundred and seventy nine.
