Improvements in Looms for Weaving Wire Cloth.
1, WILLIAM BEGG, of 633 Springfield Road, Parkhead, Glasgow, in the County
of Lanark, Wire Cloth Manufacturer, do hereby declare the nature of this
invention to be as follows:
This invention has for its object to adapt wire looms for weaving with the wire
warp composing the shed carried vertically or approximately vertically instead of
extending horizontally from the warp beam to the fell or cloth beam in order that
the weight of the shuttle carrying the weft may be transferred from the warp to
the reed and bending or sagging of the wires composing the warp may be avoided.
Under the invention the side frames of the loom are arranged to carry the warp
beam near the floor and the cloth beam overhead, and the warp on its way from
the warp beam to the fell is led over or between guide rollers serving to maintain
the warp by which the shed is formed in the same vertical or approximately
vertical lines irrespective of variations of diameter of the warp and cloth beams
as the weaving proceeds. The warp is led through a reed or comb placed
horizontally and provided with side walls or guides so as to form a race or guide-
way for the weft shuttle which is thrown or traversed over the reed between the
vertical warps composing the shed. The formation of the shed is effected by
heddles operated by ordinary means but horizontally instead of vertically. The
lay is reciprocated in an approximately vertical line by the usual crank and
connecting rod from the main driving shaft of the loom and in order that the
crank may be relieved of its weight the lay is carried upon a lever or levers
centred on the loom frame and carrying a counterbalancing weight which is also
utilized in giving the requisite blow of the lay in beating up the weft. The warp
and cloth beams are or may be provided respectively with let off and taking in
motions.

Improvements in Looms for Weaving Wire Cloth.
I, WILLIAM BEGG, of 633 Springfield Road, Parkhead, Glasgow, in the County
of Lanark, Wire Cloth 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:-
This invention has for its object to adapt wire looms for weaving with the
wire warp composing the shed carried vertically or approximately vertically
instead of extending horizontally from the warp beam to the fell or cloth beam
in order that the weight of the shuttle carrying the weft may be transferred from
the warp to the reed and bending or sagging of the wires composing the warp may
be avoided.

page_text: Under the invention, which is illustrated by the accompanying drawing, the
figure being a vertical section of a loom, the side frames A are arranged to carry
the warp beam B near the floor and the cloth beam C overhead, and the warp D
on its way from the warp beam B to the fell C is led over or between guide
rollers E, F, serving to maintain the warp D by which the shed G is formed in
the same vertical or approximately vertical lines irrespective of variations of
diameter of the warp beam B and cloth beam C as the weaving proceeds. The
warp D is led through a reed or comb H secured on a lay S the reed or comb
being placed horizontally and provided with side walls or guides I so as to form
a race or guideway for the weft shuttle which is thrown or traversed over the
reed H between the vertical warps composing the shed G. The formation of the
shed is effected by heddles K operated by ordinary means but horizontally instead
of vertically, the means illustrated consisting of pivoted levers L acted on by
cams M on a rotating shaft N, the heddles moving on guides K' on the frame A
of the loom and the harness O of the heddles being attached to the levers L.
The lay is reciprocated in an approximately vertical line by the usual crank disc P
and connecting rod Q from the main driving shaft or from the crank shaft R
of the loom and in order that the crank P may be relieved of its weight the lay S
is carried upon a lever or levers T centred on the loom frame and carrying a
counter-balancing weight or the lay may be connected by means of a lever to a
cam which acts only to draw down the lay and releases it when the balance
weight is to be utilized in giving the requisite blow of the lay S in beating up
the weft. The warp and cloth beams are or may be provided respectively with
let-off and taking-in motions.
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. A loom for weaving wire cloth the parts of which are constructed, arranged
and combined substantially as described with reference to the accompanying
drawings.
2. A loom for weaving wire cloth arranged to weave a vertical web, and in
which the shed forming warps are maintained in approximately vertical lines
irrespective of variations of diameter of the warp and cloth beams substantially
as described.
3. A loom for weaving wire cloth having its lay fitted to reciprocate in an
approximately vertical line and carried on a lever or levers provided with a
counter-balancing weight substantially as and for the purpose set forth.
