PROVISIONAL SPECIFICATION.
Improvements in Pattern Chains or similar Devices Used in
Weavers Power-looms.
I, JEAN BENAZET of Verviers Belgium, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
My invention relates to a new card made of sheet metal and it is adapted to all
power-looms.
Numerous objections are raised against the draught and tie as arranged with
rolls, such being cumbersome heavy and costly. The paper system. has also
serious defects due to the scratching of the paper, entailing considerable expense
and rendering the apparatus very delicate. I have endeavoured to avoid these
inconveniences by the use of cards made of sheet metal, adapted to the curvature
of the cylinder and perforated with suitably shaped holes to receive lifters made of
hardened steel ribbon, stamped sheet iron or cast metal.
The shape of the ends of the lifters permits them to be firmly fixed on the cards.
The lifter may also be fastened to the card by means of a tringle inserted in
a slot or by small spiral springs.
These lifters which I fix to my card by various devices, raise the lifting-wires
of the loom treadles just as they are arranged without altering them in any way.
The cards are joined by means of rings.

COMPLETE SPECIFICATION.
Improvement in Pattern Chains or similar Devices Used in.
Weavers' Power-looms.
JEAN BÉNAZET of Verviers, Belgium Manufacturer, 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 :-
The accompanying drawings represent my various kinds of card or pattern.
Fig. 1 is a front projection of the card with lifters.
Fig. 1 is a section taken on the line A-B of Fig. 1.
Fig. 2 is a front projection of the card with lifters.
Fig. 2 a section through C-D of Fig. 2.
Fig. 3 a front projection of two cards with lifters connected with each other by
Finge

page_text: Figs. 5, 6, 7, 8, 9 and 10 are plan views of the lifters M, used with the card
shown in Fig. 1.
Fig. 11 is a sectional view of the lifters M, included in Figs. 5 to 10, shewing
them as they are placed on the card.
Figs. 12, 13, 14, 15 are plan views of the lifters M, for use with the card in
Fig. 2.
Fig. 16 is a sectional view of the lifters M, included in Figs. 12 to 15, shewing
them as they are placed on the card.
Figs. 17, 18, 19, 20, 21 & 22 are views of the lifters M, intended for the card
sbewn in Fig. 3.
Fig. 23 is a sectional view of the lifters M, included in Figs. 17 to 22.
Figs. 24, 24 and 25 are sectional views of the flanged lifters M, with card, as
they are used with the card shewn in Fig. 3.
Fig. 26 is a sectional view of a lifter M, intended for the card shewn in Fig. 3.
Figs. 1, 2, 3 represent cards made of sheet metal, bent or curved according to
the curvature of the cylinder and pierced with holes Ó, of suitable shape to receive
the different kinds of lifters I am going to describe.
These cards, shewn in their actual size, are perforated according to the number
and the distances of the pedals and the hooks or lifting-wires of the loom; they
are united to each other by rings E, to form an endless chain, as shewn in Figs. 3,
3¹ and 4.
Fige. 5, 6, 7, 8, 9, 10 & 11, are views of the lifters which are made of tempered
steel ribbon; the shape of their ends enables them to be fixed in a solid fashion on
the card shewn in Fig. 1.
Figs. 12, 13, 14, 15 & 16 are also lifters made of tempered steel ribbon, the
shape of their ends and the rectangular hole K enable them to be fixed firmly to
the card shewn in Fig. 2.
The small round holes L, which are shewn in Figs. 5 to 10 and 12 to 15, serve,
with the help of a special kind of pincers to place them in position and to lift
them easily from the card.
Figs. 17, 18, 19, 20, 21, 22 & 23 are detail views of a lifter made of stamped
sheet metal are of any cast materials; to fix them on the card, shewn in Fig. 3
the lifters M are introduced into the holes O, and by means of a rod, P, passing
through the slide X, of the lifters M, they are firmly fixed in position.
The rod, P, is held in its place by means of a small pin Z, which passes through
the rod and the card.
Figs. 24 & 24 are views of flanged lifters, made, like the others, of stamped
metal sheets or any cast material, and intended for the card shewn in Fig. 3.
These two descriptions of lifters are easily inserted in the holes O, of the card
shewn in Fig. 3, the flanges being at the ends of the two springs and made of the
same piece, thus facilitating the movement of entering and leaving the hole.
Fig. 26 is a view of a lifter M, made of any cast materials and intended for the
card shewn in Fig. 3 being fixed in the same manner as the lifters included in
Figs. 17 to 23.
The different kinds of lifters, included in Figs. 5 to 26, are multiple ones, so
that they can shut one or several holes at the same time according to the exigencies
of the pattern.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim as my sole and exclusive property is :-
The above-described pattern chain in its entirety, being formed by the union of
curved or arched metal sheets perforated with holes of suitable shape, for all kinds
of mechanical weavers' power-looms with the faculty of constructing my lifter in
the exact shape and form of a half roll, either of tempered steel ribbon, of stamped
sheet metal or of any cast substance whatever, to be fixed on my card by the

page_text: fastening methods represented in the accompanying drawings, or by any other
means that practice may suggest to me, the whole as described and for the purpose
specified.
