I, HARVEY HADDEN, trading as I. and H. Hadden & Co., of Stanford Street,
Nottingham, Manufacturor, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the construction, arrangement, and mode of operating
traverse warp machines and consists ;
1. In arranging a movable needle bar to a traverse warp machine in any position
suitable for the production of a fabric.
2. Substituting a trick bar for a movable sinker bar in a traverse warp machine.
3. Using few (say two instead of four) guides, over which threads run in a traverse
warp machine.
4. In a novel method of winding up work by qualities in traverse warp machines. This
is effected by means of a ratchet wheel and paul, the paul being adjustable by link
and shifting stud mechanism so that one or more teeth may be slipped by the paul,
and to engage only in the teeth of the ratchet wheel due to the quality of the work
to be produced.
5. To a novel arrangement of the working parts constituting the machine as a whole
as hereinafter described, several of the parts known in a plain warp machine being
modified to adapt them for traverse work.
For the purpose of this invention, according to one arrangement I make the needle
bar or carrier movable at an angle, the movement being governed by cheeks partly
embracing a cam, the rotation of which causes a beam to vibrate and the needle bar
or carrier to partake of the necessary motion.
In connection with the needles I use tricks instead of sinkers and above the tricks
I arrange a presser to act upon the needles and another presser to act upon the
threads from bobbins passing over the work bars, which bobbins travel round the
machine.
Between the work bar and the needles but at a lower level I arrange a selecting bar,
a still bar and a nib bar all of which are governed by cams preferably arranged
on a main shaft operated direct or by crank or connecting levers

page_text: The trick bar is arranged that the tricks turn the work over, the needles passing
through and to and fro, the threads being put over the beards of the needles by the
nib bar and are held by the still bar after being selected by the selecting bar. Work
bars hold the threads in position.
The trick bar is attached to top rail which also carries the needle bar, the presser
bar, the thread presser and the needle bar check.
The work produced by this construction or arrangement of traverse warp machine
is preferably silk and cotton taffeta for gloves and known as Milanese taffeta but other
fabrics of a similar character can be produced by it, the threads of which run diagonally
instead of straight like stocking web as in a plain warp machine.

2. Substituting a trick bar for a movable sinker bar in a traverse warp machine.
3. Using few (say two instead of four) guides, over which, threads run in a
traverse warp machine.
4. In a novel method of winding up work by qualities in traverse warp machines.
5. To a novel arrangement of the working parts constituting the machine as a
whole, several of the parts known in a plain warp machine being modified to adapt
them for traverse work.
For the purpose of this invention, which I show on the annexed drawings,
Figure 1, this being a part sectional view of a traverse warp machine, A is the
needle bar set at an angle in the cap plate B and is operated by angled levers or
beam Chung on a joint D and governed by a cam E on the main shaft F for
producing an up and down angled motion of the needles G.
H is one of the tricks or hooks, which I use in place of the usual sinkers and I is
a presser suspended from above the tricks, so that it can be caused to press upon the
needles and J is another presser to press upon the threads which come from
bobbins K, L, after said threads pass over the work or guide bars M, N, The
bobbins are carried by standards on base plates P P having rollers P1, P1, to traverse
on a tram plate P', and round a pivot Q near each end of the tram plate P2
under the action of gear wheels R, S, from a shaft T the upper end of which carries
a worm wheel driven from a worm on the main driving shaft F.
U is a selecting bar with points V arranged between the work bar N and the
needle G, and W is a steel bar with points ✗ close thereto. Y is a nib bar, the nibs
of which have a reciprocating circular motion from a cam on the main shaft F
through suitable levers and crank arms for placing the loops over the needles.
Figure 2 shows my arrangement of appliances for winding up work according to
qualities, a is a ratchet wheel on the winding up roller Z' which transmits the work
to the work roller Z, the axle of which moves in slots of the support as the drum
fills, 6 is a paul for operating the ratchet wheel a by a step by step movement, each
time the lever c is depressed, the movement being transmitted through the lever d,
link e and tail end of the paul lever g.

page_text: The levers d and fare slotted and as the various qualities of work have to be pro-
duced the link e by being placed further from the points i, j, would cause the paul b
to travel over two or three teeth of the ratchet wheel a and so take up a coarse
work at a quicker rate than that necessitated by fine made work, the motion of the
lever c being always the same under the direction of its cam.
The two bobbins K, L are shown with two distinct methods of regulating their
motion against the drag of their threads k, l. In one 1 show a series of pockets in
the drum with shot or spheres m which rise on the drag-half travel of the bobbins
and the shots leave the pockets in succession as they reach the top and fall into a fresh
pocket for rising again.
The other bobbin has a strap n, one end of which has a weight p attached, the
other end being secured to a lever q, as a break to the drag of the thread l.
I have not given a detail description of all the parts of my novelly arranged
traverse warp machine, because most of the parts are well known in the Lace trade
but it will be seen by examination of the drawing (Figure 1) that I have materially
reduced the space usually occupied by compacting the various motions, in consequence
of which the machine travels quicker than other machines and a greater production of
work is obtained at less cost.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
1. In a traverse warp machine, the angle-wise motioned needle bar A arranged
substantially as described and shown on the annexed drawing Figure 1, for the
purpose set forth.
2. In a traverse warp machine, the substitution of movable tricks H for movable
sinkers as described and substantially as shown in the annexed drawing Figure 1.
3. In a traverse warp machine, the employment of two guides only (M N) over
which the threads k, 1 run as set forth.
4. In a traverse warp machine, the apparatus shown at Figure 2 of the annexed
drawings, by which the same drum Z' can be employed for winding up work by qualities
as described.
5. The particular arrangement of parts and their method of operation and con-
stituting a traverse warp machine for producing silk and cotton Taffeta (Milanese
Taffeta) and similar fabrics as described with reference to Figure 1 of the annexed
drawing.
