1 WALTER BRIERLEY of Town Hall Buildings Halifax in the County of York,
Patent Agent, do hereby declare that I am in possession of an invention for
"IMPROVEMENTS IN CIRCULAR LOOMS," to be as follows:-
For operating in circular looms the movement of the shuttles with the weft between
the threads of the warp in a continuous manner we have invented the movement and
the construction as follows:-
On a fixed support, or axle, and to its upper conical formed end we apply a ring
by means of four or more spokes, or arms. In this ring is engaged an annular leaf, a
second similar leaf is fixed to the ring. The latter is attached to a second ring which
is provided with a groove by means of by means of arms, or spokes, and is fixed in
four or more vertical supports.
The two leaves serve to guide the needles one of which is placed always between two
teeth of the leaves. One of the ends of the needles engages in the groove of the ring
whilst the other end remains with a slight groove in it upon an eccentric. There are
applied to the circumference of the disc turning round the axle or pivot at regular and
equidistant intervals four or more of such eccrentrics which are attached to a lever of
an arresting or stopping mechanism.
A second eccrentric ring is also fixed to the disc, and to two three or more arms,
which join the disc with hollow cylinder or socket turning round its axle. These
eccentrics raise the needles one after another by means of its inclined face till they
pass the weft against the weft or ware-board whilst the eccentric returns them to their
original position.
The shuttle remains upon the flat laying needles and stay, with one of its sides
against the teeth fixed to the leaf at small intervals. The push of the needles facilitates
their rising movement against the inclined face of the shuttle ends and forces them to

page_text: advance. The movement of the disc is operated by means of a toothed wheel which
engages with a like wheel, a toothed ring is joined to the disc by arms or spokes. The
movement of the harness is operated in known manner by eccentrics and hevelled
levers which are arranged beneath the looms. To obviate shocks to the shuttle we have
applied an arrangement which stops the loom if the shuttle is trapped or makes fault,
comprising a lever on which the shuttle when detained presses thereby disengaging a
coupling and stopping the loom. The needles may be formed or constructed in
different manners and they can be moved in different ways; a suitable arrangement
is that the needles work by a horizontal movement the same work by staying or
pushing with their ends against the hind part of the shuttle and with their other end
against the board of the web. In lieu of a harness with heddles there may be employed
also needles with holes in the midst of their length to introduce the warp thread, and
which are moyed by eccentrics which enter the groves of their ends.

Improvements in Circular Looms.
I, WALTER BRIERLEY of Town Hall Buildings, Halifax, in the County of York,
Patent Agent, do hereby declare the nature of the said invention for "IMPROVEMENTS
IN CIRCULAR LOOMS communicated to me from abroad by Robert Santer of Sulgen
Mechanician A. Hugo of Riesbach Merchant and Edward Naef of Winterthur
Merchant all in Switzerland, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
For operating in Circular looms the movement of the Shuttles with the weft between
the threads of the warp in a continuous manner we have invented the movement, and
the construction as follows. On a fixed support, or axle and to its upper conical
formed end we apply a ring by means of four or more spokes, or arms. In this ring
is engaged an annular leaf, a second similar leaf is fixed to the ring. The latter
is attached to a second ring which is provided with a groove by means of arms or
spokes, and is fixed in four or more vertical supports. The two leaves serve to guide
the needles one of which is placed always between two teeth of the leaves. One of
the ends of the needles engages in the groove of the ring, whilst the other end remains
with a slight groove in it, upon an eccentric. There are applied to the circumference of
the disc turning round the axle or pivot at regular and equidistant intervals four or more
of such eccentrics which are attached to a lever of an arresting or stopping mechanism.
A second eccentric ring is also fixed to the disc, and to two, three, or niore arms,
which join the disc with hollow cylinder or socket turning round its axle. These
eccentrics raise the needles one after another by means of its inclined face till they pass
the weft against the ware or web board whilst the eccentric returns them to their
original position.

page_text: staying or pushing with its cant or incline a against the back part of the shuttle S and
with its cant or incline against the board of the web c the arrows indicate the
alternate movement. In lieu of a harness with heddles, there may be employed also
needles P with holes in the midst of its length through which is introduced the warp
thread, and which are moved by eccentrics, the latter enter the grooves R of their
ends.
Having now particularly described and ascertained the nature and object of iny said
invention, and in what manner the same is to be employed I declare that what I
claim is
A circular loom with horizontal needles, in which the movement of the shuttles S
with the weft between the threads of the warp is operated in a continuous manner by
means of two ring formed eccentrics F and F which guide and work the moveable
needles P.
