PROVISIONAL SPECIFICATION.
Improvements in Loom Selvage Shedding Apparatus.
We GEORGE GREAVES, Mill Manager, and HARDMAN BROTHERS AND
COMPANY LIMITED Manufacturers all of New-Hall-Hey Mills Rawtenstall in
the County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in looms for weaving, the object of the
invention being to enable the loom to weave plain tabby selvages whilst the body
of the cloth is being woven to a satteen or any other fancy pattern.
For this purpose we fix at each side of the loom a bracket supporting a narrow
perforated board or plate like the cumber board of a Jacquard harness and
through these perforations we pass a series of heald cords provided with mails,
and fitted beneath with elastic cords or springs.
Above the cumber board the heald cords are tied in two groups and are connected
to two levers or jacks above the loom, which are actuated by a strap passing over
a pulley fixed on the stud which carries the levers or jacks the upper end of the
strap being connected to a coiled spring fixed to the loom side, and the lower end
attached to a treadle worked by a tappet on the tappet shaft.
The selvage ends or warps are drawn in through the mails of these heald cords
and as the tappet revolves it depresses the treadle and pulls one half of the selvage
harness up and lowers the other half, and as the tappet leaves the treadle the
coiled spring above named reverses the action raising the treadle, and thus causing
the selvage healds above named to weave plain tabby at each edge of the cloth
whilst the ordinary healds are weaving satteen or other fancy pattern.

CUM LEID DI DUIFICATION.
Improvements in Loom Selvage Shedding Apparatus.
We GEORGE GREAVES, Mill Manager, and HARDMAN BROTHERS AND
COMPANY LIMITED Manufacturers, of New-Hall-Hey Mills Rawtenstall in the
County of Lancaster, 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 improvements in looms for weaving, the object of the
invention being to enable the loom to weave plain tabby selvages whilst the body
of the cloth is being woven to a "satteen or any other fancy pattern.
"
The nature of the said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1 is a side view of so much of a loom as is necessary to show the application
of my invention thereto, Fig. 2 is a front elevation of the same and Fig. 3 a partial
plan view thereof.
a is part of the frame of the loom, 6 the crank shaft c the tappet shaft, d the
ordinary healds, e the warp b-am and the cloth roller.

For the purposes of our invention we fix at each side of the loom a bracket
supporting a narrow perforated board or plate or heald comb h, like the cumber-
board of a Jacquard harness, and through these perforations we pass a series of
heald cords provided with loops or mails and fitted beneath with elastic cords ¿+
or with springs, or weights."
Above the heald-comb or cumber-boards the heald cords are tied in two
groups which are connected to two levers or jacks above the loom which are
actuated by a strap passing over a pulley m fixed on the stud n which carries the
levers or jacks k, the upper end of the strap being connected to a coiled spring o
fixed to the loom frame, or to a weight, and the lower end thereof attached to a
treadle k+ worked by a tappet p on the tappet shaft c.
The selvage ends or warps are drawn-in through the loops or mails of the heald
cords i, and as the tappet p revolves, it pulls one half of the selvage harness i up,
and lowers the other half, and as the tappet p leaves the treadle k+ the coiled
spring o above named reverses the action raising the treadle k+ and thus causing
the selvage heald cords i to weave plain "tabby" at each edge of the cloth whilst
the ordinary healds d are weaving satteen or other fancy pattern.
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 combination with the ordinary healds of a loom of an auxiliary set of
heald cords at each side of the warp provided with loops or mails, such heald
cords passing through narrow perforated cumber-boards heald comts or plates,
and being actuated by a treadle and a special cam fixed on the can shaft for the
purpose of weaving plain "tabby" selvages whilst the ordinary healds are weaving
the body of the cloth to a "satteen or other fancy pattern.
