page_text: COMPLETE SPECIFICATION filed by the said Louis Vignat at the Office of
the Commissioners of Patents, with his Petition and Declaration, on the
11th December 1856, pursuant to the 9th section of the Patent Law
Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LOUIS
VIGNAT, of the firm Vignat Frères, of No. 3, Place, des Victoires, in the City
of Paris, Merchants, send greeting.
WHEREAS I am in possession of an Invention for "A NEW SLIDE BEATER
WITH ONE OR MORE SHUTTLES, APPLICABLE TO ANY LOOM WHATEVER FOR WEAVING ALL
KINDS OF TISSUE," and hävo petitioned Her Majesty to grant unto me, my
executors, administrators, and assigns, Her Royal Letters Patent for the same,
and bave made solemn declaration that I verily believe myself to be the first
and true Inventor thereof.
NOW KNOW YE, that I, tho said Louis Vignat, do hereby declaro that
the following Complete Specification, under my hand and seal, fully describes
the nature of my said Invention, and the manner in which the same is to be
performied (that is to say) :-
Explanatory notice relating to a loom called the sliding, for machinery
employed to manufacture all kinds of woven material, such as silken, woolen,
and cotton stuffs, ribbons, cloth, silk handkerchiefs, crapes, &c. &c., whether
the machinery be worked or not by mechanical means, but more especially for
ribbons, lace, and passementerie. The system applies not only to looms with

page_text: one warp, but also to those with several, superposed one on the other, answering
to the manufacture of striped and plaided stuffs. It alters entirely the
mechanical organization employed up to this time in the newest machines,
and this important modification makes a valuable part of the Patent. Among
the numerous advantages that are presented by this system there are two very
important ones that we may mention here. The old loom describes a curve
moro or less great above or below the machine, according to the position of
the axle to which its arms are attached; and this curve, besides increasing by
a great deal the space required by the loom, also subjects the chain threads
to rubbing against the teeth of the comb in its entire height, which deteriorates
considerably the chain, withdraws strength from the threads, and renders them
easy to be broken. In this sliding loom, on the contrary, the movement
operates in a direct line, the space as well as the rubbing of the chain against
the teeth of tlie comb are diminished greatly. In consequence, this system
increases by a third the velocity of the loom, economizes by as much again the
workmanship, and enforces a larger production, either by the rapidity of the
imotion, or by the better state in which it preserves the chain threads.
Figure 1, side view of a plan of a loom encased in a slide by means of two
small iron cars, which serve to guide it, and give to it constantly a direct
backward and forward motion when the machine is at work.
This, the first and principal idea of the system, is called the railroad. A, A,
moveable piece, with wooden or iron groove, which permits the elevation of
the loom to the height that the stuff requires. To this piece, B is joined,
serving as a rail, on which run the cars C, C, which direct the motion of the
Joom, and which can be withdrawn by displacing B, which takes off D,
foundation of the machine, on which are fixed A, B; E, E, strap giving
motion to the warps F, conducting the loom on the railroad. These two
Figures E, F, are adapted to the fly G, fixed to the large centre beam.
.
Figure 2, front view of a loom with one or several warps. A, A, parts of
the loom, in hard wood, between which the warps are placed; B, the lower
part of the loom; C, small slide, called the ruller (reglette), receiving a
horizontal movement from the pole D, and transmitting it to E, to which it is
fixed by a crank; E, in working more or less, causes the part A, A, of the
Joom to mount, as it is indicated by Figure 3. F, sinal wheel serving to
render softer the ascending movement of the loom; G, support of the ruler;
II, elastic buffer, serving to decrease the work of the lever E.
Figure 3, new mounting system, to be adapted to the loom for several warps,
and to cause to mount the part A, A, to the necessary point for the departure

page_text: of each warp. A, lower part of the loom; B, ruler; C', C', supports of the
rulers; these pieces are the same as those of Figure 2. D, D, handle serving
to give an horizontal direction to the ruler B in the slide C', C'; E, pivot on
which the handle turns; F, holding to the pivot E at the lower part of the
loom and following its movement; G, cylinder receiving the impression from
the mounters i, i, i, and transmitting it by D to the ruler B, in order to raise
the moveable part of the loom called the comb to the required height for the
passage of the warp's passage, indicated by the bolts J, J, J, which direct the
cards of the jacquard mechanism; H, foundation of the loom, on which is
fixed the mounter for several levers, according to the quantity of the warps,
i, i, i, levers of the mounters, put in communication by the bolts J, J, J, with
the jacquard mechanism by means of cords which are attached to it. These
levers are more or less raised according to the position of each of the warps to
which they correspond, and placed under the cylinder G; they give it a curve
more or less long at the moment when it escapes in following the motion given
by the loom.
Figure 4, piece placed in front of the jacquard mechanism, with which it
puts in communication by means of cords, there attached, the bolts that serve
to regulate the departures which raise the warps to the required height. A,
part attached to the bars of the mechanism, and giving a vertical movement to
the slido B, which raises the part C' by means of a hole, in which enters the
button F, fastened to C; C", moveable part, sustained at a distance from B
by the buffer E. When the needlo D, governed by the mechanical law, pushes
the bolt G, this forces down the button Fin the slide B, which can then raise C'.
This mechanism may be doubled or tripled, according to the quantity of the
warps that it may be necessary to put in motion. K, part of the side view of
Figure 3, indicating the form of the levers and the situation of the bolts.
Figure 5, sliding loom; the last result of the improvements of this Invention
answering to the same end as the loom with railroad of Fig. 1, but much
simpler and more economical. The difference consists in the iron or wooden
slide A, on whose length the backward and forward movement of the loom is
operated; the remainder of the parts conform to Figure 1. B, wooden or iron
supports, adapted to the foundation of the machine, and which carry the slide;
C, inferior part of the loom, hollowed to the calibre of the slide; in this slide
are fixed brazen sockets for facilitating the motion of the loom.
It is perfectly understood that all other arrangements relating to change of
forin, which acts in the same manner and arrives to the same results by the
samo principles, are reserved.

page_text: The examination of all these parts will cause easily to be understood the
immense advantages of this Invention; and it is evident that by this system
there will be obtained. more regularity in the tissue, a largar amount of produce
in the same time, 'a real economy in the workmanship, and a more beautiful
manufacture.
In witness whereof, I, the said Louis Vignat, have hereunto set my
hand and seal, this Eleventh day of December, One thousand eight
hundred and fifty-six
