COMPLETE SPECIFICATION.
An Improved Power Loom for Weaving Wire Gauze or Wire
Cloth.
I, ERNST HUSCHKE, of Saalfeld, Sachsen-Meiningen, North Germany, Machine
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to be performeil, to be particularly described and ascertained in and by the
following statement :-
-:
My invention relates to a power loom for weaving wire gauze or wire cloth, in
which the lay moves vertically up and down the loom frame and in which the warp
threads are vertically arranged. In combination with this arrangement a so called
39
disc
shuttle is employed, which leads the wire from the bobbin in the direction of
the weft and renders it possible to weave into wire gauze or wire cloth almost any
metal wire, if flexible.
"
In order to guide the wire at the selvages of the ganze or cloth a pointer is employed,
at each side of the loom frame, which is adapted to be pressed backwards from the lay
as the shuttle is thrown and to spring forward before the return throw of the same,
thus always catching the last weft thread so that the following thread is bent round the
pointer into its proper position.
In order to obtain the force necessary for throwing the shuttle when the wire gauze
or wire cloth is made from stout or thick wire springs are employed, which in com-
bination with apparatus for imparting tension to them considerably facilitate the
weaving of the said stout or thick wire into gauze or cloth.
In order that my invention may be thoroughly understood I have appended the
accompanying sheets of drawings, in which similar letters of reference indicate
corresponding parts.

Since the shuttle travels on the lay the mechanism for operating or throwing the
shuttle is attached to the lay. This mechanism, which is placed at each end of the
lay, consists principally of the driving bolt & which is guided in the stout barrel k¹.
The bolt & provided on its upper side with a ridge or projection which fits in a
groove formed in the barrel, and is thus prevented from turning round in the barrel A'.
The bolt is also provided with a projection which is gripped by the end of a lever
as hereinafter described. A spring, which supplies the necessary force for throwing
the shuttle, is placed at each end of the lay band is attached at its lower end to the
vertical support which is fixed to the lay b. The upper end of the spring & resis
against the roller carried by the end of the bolt k.
To the standards a, a of the loom frame are pivotted two levers m, m, which are
077

page_text: provided with upper arms projecting beyond their centres or pivots. The levers m, m
when in their positions of rest lean against projections on the loom frame and are thus
held at a certain angle to the standards a, a of the loom frame. The levers m, m aro
placed exactly over the middle of the lay b, and their lower arms are bent and provided
with slits.
When the lay moves upwards it will strike, at a certain point in its travel, the
levers m, m which will then slide along the barrels k¹, until the slits in their lower
arms grip, or become engaged with the projections k², 2 on the bolts k, k. As tho
upward movement of the lay is continued the two bolts k, k will be driven outwards
and consequently tension will be imparted to the springs, Shortly before the
lay has reached the end of its upward movement small bars n, n, Figs. 5 and 6, fall,
owing to the action of springs n¹, n', in front of ridges ³, formed on the bolts k, k.
By means of the bars n, n the bolts k, k are held back and the shuttle provented from
being thrown. By the above described mechanism tension is simultaneously
imparted to the two springs k, and the force with which the driving bolts k, k
throw the shuttle is proportional to the amount to which the springs are
stretched.
The bolts k, are released by an arrangement which is independent of the apparatus
used for imparting tension to the springs k, k, and which operates first on one side of
the loom frame and then on the other. The bar n on one side of the lay b and then
the bar on the other side of the lay b come against a rod o which is supported by the
Joom frame in a position parallel to the lay b. The rod o is adapted to slide a short
listance first to one side of the loom frame and then to the other side. To the rod o
is attached the rod of which is pivotted at o² to the loom frame and is provided at its
lower end with a fork between the arms of which a disc o³ turns. The disc o³ is
mounted onl a shaft carried by the loom frame and is provided with two
projections o, o one on each side or face. The projections 01, 0 are placed
diametrically opposite to each other. As the disc o revolves the rod o' is moved
sideways and consequently the rod o is driven from side to side of the loom frame
projecting alternately on each side of the same and raising the bars n, n against the
action of the springs n', ' first on one side and then on the other side of the lay b,
thus allowing the bolts k, k to be moved by the springs, and the shuttle to be
thrown.
The bars n, n in their upward movement actuate small catches which are employed
for the purpose of retaining the shuttle at each end of its throw and which must
be displaced before it can be thrown again. Referring more particularly to
Figs. 5, 6 and 7, each of the bars n, n is lengthened so as to project beyond its
pivot n² and is connected at this end by the rod to the lever which is fixed
to the shaft r. The shaft is supported by brackets 3 which are attached to the
lay . To the end of the shaft is fixed the nose which rests against one end
of the double armed lever 6. One end of the lever 76 is curved and is pressed
by a spring into a recess cut in the side of the shuttle p. When the
shuttle arrives at the end of it throw the end of the lever 7 passes into the
recess and retains the shuttle. When the bolt is released by the raising of
the barn, at each side of the lay b, the shaft is turned by means of the rod
and the lever and the nose is pressed against the end of the lever in such
a manner as to remove its other end from the recess formed in the shuttle p
and leave the shuttle free to be thrown.
The shuttle p consists of a pulley or disc p so arranged on the carriage p² that
the wire is always unwound in the direction of the weft, which is the only possible way
of successfully feeding a loom with stout wire. The carriage p² is supported by the
rollers p³, p.
The apparatus for guiding the wire at the selvages of the wire gauze or wire cloth
consists of the two pointers 7', y fixed to the bar which is suspended, by the
arms g³ ³, from the pivot q. The arms q, q3 form parts of angle levers which are
connected to each other. The horizontal arm of one of the angle levers is connected,

page_text: 1
as shown in Fig. 2, to the lever q which is pivotted at one end to the loom frame.
The lever projects so far forward that it is struck by the lay 6 and pushed upwards
during the upward movement of the lay b. By this means the angle levers g³, 9³ will
be swung on their pivot q' and will move the pointers q', q' backwards. During the
downward movement of the lay b the lever g³ is drawn back into its original position
by means of a spring and the pointers 7', q₁ project again. The pointer then
catches the wire, which is bent round the same and held in the proper position for
the return throw of the shuttle.
The loom is provided with a governor for regulating the speed of the fabric beam
according to the mesh of the wire gauze or wire cloth to be woven.
The other parts of the loom are well known and need no special reference.
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 is:-
(1). The combination with a lay having a vertical up and down motion and a warp
vertically arranged of the shuttle consisting of the disc or pulley mounted on the
travelling carriage and adapted to unwind the wire parallel to the direction of the
weft, as and for the purpose described herein and illustrated by the accompanying
drawings.
(2). The combination with a lay having a vertical up and down motion and a
warp vertically arranged of the mechanism for imparting tension to the springs of the
driving bolts consisting of levers pivotted to the standards of the loom frame and

during the upward movement of the lay and thereby force the driving bolts out-
wards and impart tension to the springs acting on the same, and bars arranged to fall
down by means of springs in front of ridges on the driving bolts and prevent the
shuttle from being thrown, as described herein and illustrated by the accompanying
drawings.
and down motion and a

immediately the lay commences its downward movement, as and for the purposes
described herein.
(6). The combination with a lay having a vertical up and down motion and a
warp vertically arranged of the pointers g', y' carried by the angle lovers q³, q³
swinging on the pivot q' and connected to the lever q which is pivotted at one end to
the loom frame and projects out at the other end into the path of the lay and a spring
for drawing the lever q back to its original position when it is not in contact with the
lay, as described herein and illustrated by the accompanying drawings.
