'IMPROVEMENTS IN APPARATUS FOR CHANGING SHUTTLES IN LOOMS." [A com-
munication from abroad by Auguste Henri Berger, of Paris, France.]
This Invention relates to apparatus for changing shuttles in looms for the
purpose of weaving fabrics with varied wefts. Usually shuttles for this purpose
are contained in compartments of boxes mounted on the batten of the loom, these
boxes being moveable by pattern mechanism horizontally, vertically, or round axes,
so as to bring one or other of their compartments in line with the shed for the
purpose of throwing the shuttle contained in that compartment. According to the
present Invention each shuttle box is made stationary on the batten, having its
compartments converging towards the shed, and a switch or oscillating guide plate
is mounted on the batten, so that by means of the pattern mechanism it can be
brought in line with one or other of the compartments of the shuttle box, and so
complete the path for the shuttle from that compartment to the shed in a manner
similar to the shifting point of a railway. By this arrangement the pattern
mechanism, having to move only the comparatively light switch, instead of the
whole shuttle box, can work with increased facility and rapidity, and there being
less liability to derangement of the loom than when the shuttle box is moved,
the loom can be worked faster and its production can be correspondingly
increased.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an end view, and Fig. 2 a front view of a loom to which means according
to this Invention are applied for changing shuttles; Fig. 3 is a front view drawn
to an enlarged scale of one of the shuttle boxes; Fig. 4 is a transverse section
thereof on the line (A), (B), (C); and Fig. 5 is a transverse section of the batten.
A is the lower of two shuttles in a horizontal compartment of the box, and B is the
upper shuttle in an inclined compartment, each shot by a whip, of which there are
two at each side of the loom. On the batten near each end of it is hinged at D a
plate C which can lie horizontally to allow passage of the shuttle A over it, or can
be tilted to the dotted position C¹ for passage of the shuttle B in a manner similar
to the point of a railway. A pin E on each of the plates C is connected by a
rod F to an arm N on a rocking shaft M, an arm I on which is worked by a
lever H from a cam G. Although the Drawings shew an arrangement for changing
two shuttles only, obviously three or more might be directed into and out of the
race in a similar manner.
Having thus described the nature of the said Invention, and in what manner
the same is to be performed, as communicated to me by my foreign correspondent,
I claim,―
The use for changing shuttles in looms of a switch or oscillating guide plate
mounted on the batten and operating in combination with converging compart-
ments of stationary shuttle boxes, substantially as and for the purposes herein set
forth.
In witness whereof, I, the said John Imray, have hereunto set my hand and
seal, this Twentieth day of August, in the year of our Lord One thousand
