We GEORGE HODGSON Machine Maker, and WALTER TETLEY, Overlooker both
of Laycocks Mill, Thornton Road, Bradford in the County of York, do hereby declare
the nature of this invention to be as follows:-
This invention relates to the class of weft fork consisting of a pair of light blades
of steel operated by the inclined portion of a slide; a defect of such weft forks is
that by reason of the necessarily lightness of the blades, the latter will not fall or act
with any certainty when applied to looms running at a high speed nor are they reliable
when the weft is hairy or has many divergent fibres.
The object of this invention is to render such weft forks positive in their action
irrespective of the weight of the blades or of the speed of the loom or of the class of
weft which may be used, this we effect by combining with the slide an inclined
projecting piece, cam, lug, or other device which as the slide moves acts upon a
projecting finger or part of the blade carrier and which thus forces the carrier to
move on its centre or bearings and operate the blade fork at each and every movement
of the slide in a "positive" manner.

page_text: We GEORGE HODGSON Machine Maker, and WALTER TETLEY, Overlooker both of
Laycock's Mill Thornton Road Bradford in the County of York, do hereby declare
the nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
This invention relates to the class of weft fork consisting of a pair of light blades
of steel operated by the inclined portion of the slide, a defect of such weft forks is
that by reason of the necessarily lightness of the blades, the latter will not fall or
act with any certainty when applied to looms running at a high speed nor are they
reliable when the weft is hairy or has many divergent fibres.
The object of this invention is to render such weft forks "positive" in their action,
irrespective of the weight of the blades, or of the speed of the loom, or of the class
of weft, which may be used, this we effect by combining with the slide an inclined
projecting piece, cam, lug, or other device which, as the slide moves, acts upon a
projecting finger or part of the blade carrier and which thus forces the carrier to
move on its centre or bearings and operate the blade fork at each and every movement
of the slide in a "positive" manner.
Such being the nature and object of this our said invention the following is a
complete description of same reference being had to the accompanying drawings:-
Fig. 1 is a front elevation of the improved apparatus fixed on slay beam.
Fig. 2 is a plan view of fig. 1.
Fig. 3 is an end elevation.
Fig. 4 is a section of part of the apparatus
Fig. 5 is a view of the sliding plate detached.
At 1 is the breast beam to which the plate 2 is secured by screws 3, 4 is the sliding
plate receiving its motion as ordinary through the connecting rod 5 as is well under-
stood. On the plate 4 is the inclined projecting piece 6 which at each beating up
movement of the slay is caused by the movement of the sliding plate 4 to bear
against the pendent part 7 of the fork 8 and thus to bring the latter down as shewn
at fig. 4 into position for feeling for the weft, by a certain and positive movement
instead of the fork being left to descend or fall through gravitation or by chance as
heretofore. The incline 9 (fig. 5) by acting on the underside of the projecting piece 10
ensures positive lifting motion for the fork 8, and the plate 6 secures like positive
motion downwards. The movements of the fork are thus made positive both ways
whereby in addition to securing certainty of action admits of the use of weft forks of
the class illustrated to higher speed looms to which looms prior to this our invention
they were not applicable.

page_text: Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
=
The improvements herein described, comprising the pendent part 7, the inclined
projecting piece 6, slide plate 4 and fork 9 all in combination and substantially as
illustrated by annexed drawings, and operating as set forth.
Dated this 26th day of March 1888.
