IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1856

page_text: LETTERS PATENT to Henri Evette, Manufacturer, of Lizieux, Town in
the French Empire, for the Invention of "IMPROVEMENTS IN LOOMS FOR
WEAVING."
Sealed the 14th January 1857, and dated the 30th July 1856.
PROVISIONAL SPECIFICATION left by the said Henri Evette at the
Office of the Commissioners of Patents, with his Petition, on the 80th
July 1856.
I, HENRI EVETTE, Manufacturer, of Lizieux, Town in the French Empire,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
LOOMS FOR WEAVING," to be as follows:-
My Invention consists of arrangements for throwing or shooting the shuttle
in hand looms and power looms by mechanical means, in which the throw is
effected with vigour, precision, and rapidity. By means of these arrangements,
fabrics of great width may be produced, and seamless fabrics of three yards
width and upwards may be woven on power looms as well as on hand looms.
I mount two wheels, one on each side of the loom, worked by gearing
from the shaft, or otherwise, and having on the periphery of each a projecting
piece or stop. Near to each wheel I place an upright spindle, free to turn
to a certain extent in its bearings, and having a projecting arm near the top
and another near the bottom. I place a horizontal rod along the top cross
beam of the frame of the loom, the ends of which rod project downward
and are bent or hooked round. When the wheels revolve, the stops on their
peripheries come simultaneously against the lower arms on the spindles,

page_text: thereby swinging the spindles partially round, and bringing the upper pro-
jecting arms against the bent ends of the horizontal_rod, which is thereby
raised, and the ends of this rod in their turn come against levers or connecting
arms, placed one on each side of the loom; the further end of each lever or
connecting arm is connected with the upper arm of a spindle, which drives
the picker by an arm at bottom, so that when the hooked horizontal rod moves
the lever or connecting arm, the latter works the spindle, which, in its turn,
actuates the picker which shoots the shuttle. The levers or connecting arms
are alternately raised out of reach of the hooked ends of the horizontal rod by
means of vertical rods, worked by tappets, or eccentrics on the driving shaft,
so that each lever or connecting arm does its work alternately, but the
horizontal rod being raised at each end by both wheels at the same time,
precision and vigour of action result. Just as the shuttle is thrown, it is
disengaged from the shuttle box by the withdrawal of the arm of the spring
bolt, which draws it back by a chain attached to a connecting rod; this dis-
engagement may be effected by other suitable means.
I attach much importance to the liberation of the shuttle from its box
simultaneously with the throw of the shuttle.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henri Evette in the Great Seal Patent Office on the
. 24th January 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
EVETTE, Manufacturer, of Lizieux, Town in the French Empire, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria; by Her Letters
Patent, bearing date the Thirtieth day of July, in the year of our Lord One
thousand eight hundred and fifty-six, in the twentieth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said Henri
Evette, Her special licence that I, the said Henri Evette, my executors,
administrators, and assigns, or such others as I, the said Henri Evette, iny
executors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN LOOMS FOR
WEAVING," upon the condition (amongst others) that I, the said Henri Evette,

page_text: my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and ascer-
tain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Henri Evette, do hereby declare the
nature of my said Invention, and in what manner, the same is to be per-*
formed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawings hereunto annexed
(that is to say):—
:
My Invention consists in arrangements for throwing the shuttle in hand
and
power looms by mechanical means, in which the throw is effected forcibly,
rapidly, and with precision. By means of my Invention, fabrics of consider-
able width may be produced, and seamless fabrics of three yards width and
upwards may be woven on power looms as well as on hand looms. Two
wheels are mounted, one on each side of the loom, each wheel having a stud
on its periphery; near to each wheel is an upright shaft or spindle having a
projecting arm near the top and another near the bottom. Along the top
cross beam of the loom frame is a horizontal rod, the ends of which are bent
down and hooked; when the wheels revolve, the studs on their peripheries
come simultaneously against the lower arms of the upright spindles, and their
upper arms push the bent ends of the horizontal rod upward, bringing them
against other arms or bars placed one on each side of the loom, which are
connected at their further ends with a shaft or stem, which when moved by
the arms or bars just referred to, is brought against the picker, drives it, and
shoots the shuttle. These arms or bars are raised alternately out of reach of
the hooked ends of the horizontal rod by vertical rods, lifted up and down by.
cams or tappets on the driving shaft, so that each bar does its work alternately,
but the horizontal rod being raised at both ends by the two wheels at the same
time, precision and forcible action are obtained. Just as the shuttle is about
to be thrown, it is disengaged from the shuttle box by the withdrawal of the
arm of the spring bolt, which holds it by means of a chain attached to a con-
necting rod, or this releasing action may be effected by other suitable means.
The Drawings annexed further explain the nature of the Invention, and
the manner in which it is carried into effect.
Figure 1 is a side view of part of one side of a loom, illustrating my
improved arrangements. There is a precisely similar arrangement on the
other side of the loom. Figure 2, a back view of Figure 1; Figure, 3 shows

page_text: the arrangements for the alternate lifting of the connecting bars; Figure 4
shews the parts for driving the picker.
A is the shaft driven by pully and band, crank, or other means; V repre-
sents one of. two wheels, worked by gearing from the shaft A, or otherwise;
t, stud or projection on the periphery of wheel V; T, upright shaft or spindle,
having two arms, one T¹ near the bottom, and the other T" near the top:
There is a' wheel, similar to. V, with stud t, and a shaft similar to T, with like
top and bottom arms, on the other side of the loom. H, Figure 3, is a
horizontal rod, extending along the top cross beam of the loom; the extre-
mities of this rod are turned downward and bent round, as shewn at II
(Figures 2 and 3). B is an arm or connecting bar (of which there is one on
each side of the loom) bent at one end, as shewn at B', and flat at the end Z,
where it is connected to the upper arm of a shaft T, C, which drives the picker
of the shuttle by means of another arm at bottom. As the wheels V revolve,
the studs on each come simultaneously in contact with the lower arm T¹ of
each shaft T, bringing-the-upper arms-T" against, and thereby lifting the bent
ends of the the horizontal rod. H, which strikes the end B of each rod B
alternately, these bars B being alternately lifted-out of the way of the rod II
by means of. rods R, raised and depressed by cams e on the driving shaft A.
Cis a chain attached to the rod D, which draws back the spring bolt and
releases the shuttle from its box just as it is about to be driven by the stroke
of the picker.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim,
First, the arrangements for throwing or shooting the shuttles of looms
berein before described with reference to the Drawings annexed.
Second, the arrangement herein-before described, or equivalent means, for
releasing the shuttle simultaneously, or nearly so, with the stroke of the picker.
In witness whereof, I, the said Henri Evette, have hereunto set my
hand and seal, this Third day of January, in the year of our Lord
One thousand eight hundred and fifty-seven.
