Improvements in Looms for Weaving Lappet Goods.
We, RICHARD LONGDEN HATTERSLEY, of North Brook Works, Keighley, in the
County of York, Machine Maker, and SIMEON JACKSON, of the same address,
Manager, do hereby declare the nature of this invention to be as follows:
-
This, our invention, relates to looms for weaving lappet goods, and consists of
an improved arrangement of mechanism whereby a greater variety of patterns
can be made than hitherto and also the said mechanism is rendered more accurate
in its movements.
In this, our invention, the needle bars are worked from the upper side and we
make use of the false reed, carriers for needle bars, rising and falling cylinder,
and the mechanism for operating these parts, also we connect the needle bars to
their respective indicating levers same as described in our Specification of Letters
Patent numbered 24781 of 1895.
Our improvement is as follows:--The indicating lever, which controls the
position of the needle bar, and of which there may be one or more, is operated
upon by indicating pegs from a chain of lags passing over the rising and fall-
ing cylinder, the number in use and the length of each of these indicating pegs
are adapted to suit the design of the lappet to be woven. The indicating lever is
designed and a tappet, lever, and spring arranged to work in connection with
same in such a manner that after the indication has been imparted to the indi-
cating lever and thus its position determined, the lever and spring hold it in that
position till the next indication is to be imparted when the indicating lever is
released and free to be operated upon.
We attach an additional indicating lever and connect the same by rods and
lever to the dobby for the purpose of controlling the movements of the latter
from the chain of lags and pegs when necessary.

Manager, do hereby declare the nature of this invention and in what manner the

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This, our invention, relates to looms for weaving lappet goods, and consists of
an improved arrangement of mechanism whereby a greater variety of patterns
can be made than hitherto and also the said mechanism is rendered more accurate
in its movements.
In this our invention the needle bars are worked from the upper side and we
make use of the false reed, carriers for needle bars, rising and falling cylinder,
and the mechanism for operating these parts, also we connect the needle bars to
their respective indicating levers same as described in our Specification of Letters
Patent numbered 24781 of 1895.
Our improvement is as follows:-The indicating lever, which controls the
position of the needle bar, and of which there may be one or more, is operated
upon by the indicating pegs from a chain of lags passing over the rising and fall-
ing cvlinder the number in use and the length of each of these indicating pegs
are adapted to suit the design of the lappet to be woven.
The indicating lever is designed and a tappet, lever and spring arranged to
work in connection with same in such a manner that after the indication has
been imparted to the indicating lever and thus its position determined, the lever
and spring hold it in that position till the next indication is to be imparted, when
the indicating lever is released and free to be operated upon.
We attach an additional indicating lever and connect the same by rods and
lever to the dobby for the purpose of controlling the movements of the latter
from the chain of lags and pegs when necessary.
In order to make clear our invention we append hereto a sheet of drawings
marked with figures of reference in which like figures denote like parts.
Fig. 1 is an end view, and Fig. 2 a front view of our invention
The parts forming the false reed including tappet 1, lever 2, rod 3, levers 4
& 5, shaft 6, needles 7, as also the parts for operating the rising and falling cylin-
der 8, including tappet 9, bowl 10, bracket 11, are the same as claimed in our
Specification of Letters Patent 24781 of 1895
The connections from the indicating lever, or levers, hereafter referred to
including rod 12, lever 13, rod 14, lever 15, connection 16, needle bar 17,
needles 18, are also the same as claimed in the before-mentioned specification.
Our invention is as follows:-The indicating lever 20, of which there are three
shown in Figs. 1 & 2, is operated upon by the pattern surface 21 passing over
the cylinder 8, this lever is loosely mounted on the stud 22 and provided with
the indent 23. The lever 24 is in contact with the lever 20, as shown in Fig. 1
it is operated on each operation of the loom by the tappet 25, and a spring 26,
of suitable tension applied to same.
The pattern surface 21 consists of lags and pegs, the latter are of various
lengths and can be adapted for any required design. All the motion is so
arranged that when the indicating lever 20 has been operated by a peg of the
pattern surface it is rigidly held in that position, for a certain period of a revo-
lution, by the lever 24 until the latter is brought to its normal position, as
shown in Fig. 1, by the tappet 25 when the indicating lever 20 is free to be
again operated upon by the pattern surface.
We show in Figs. 1 & 2 three indicating levers 20 and three needle bars 17,
but one, two, three or more may be utilised in accord with the designs to be
made.
An indicating lever 20. spring 28, and rod 27 are added, they work in con-
nection with the dobby when so required.
.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is be performed, we declare that we
claim is:-
1st. The manner of controlling the position of the indicating lever, as shown
and for the purpose specified.

page_text: 2nd. The connection of the dobby to the indicating lever as shown and for the
purpose specified.
