PROVISIONAL SPECIFICATION.
Improvements in or relating to the Lays and Picking Apparatus
of Looms.
I, FRANZ SCHMIRK, of Grossenhain, kingdom of Saxony, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
My invention relates to looms, whether operating by means of flying shuttles or of
positively-actuated shuttles, and its object is to reduce the weight of the batten in
order to allow the same to be moved more rapidly and through a longer course without
thereby causing shocks or vibrations.
For this purpose I separate from the batten all parts serving to operate the shuttle
and to receive the same at the ends of its course, that is to say, the shuttle-boxes and
the drivers of flying shuttles and the carriers of positively-actuated shuttles, and
I mount the said parts on the frame of the loom; whereas the only part or parts
remaining attached to the batten are the reed, and, wherever required, the race-
board.
This batten may be arranged to move between fixed guides, or it may be pivoted to
the frame of the loom as usual, and the shuttle-boxes may form a single cell each, or
they may consist in drop-boxes having two or more cells.

COMPLETE SPECIFICATION.
Improvements in or relating to the Lays and Picking Apparatus
of Looms.
I, FRANZ SOHMIRK, of Grossenhain, kingdom of Saxony, 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 :-
-
My invention relates to looms, whether operating by means of flying shuttles or of
positively-actuated shuttles, and its object is to reduce the weight of the batten in
order to allow the same to be moved more rapidly and through a longer course without
thereby causing shocks or vibrations.
For this purpose I separate from the batten all parts serving to operate the
shuttle and to receive the same at the ends of its course, that is to say, the shuttle-
boxes and the drivers of flying shuttles and the carriers of positively-actuated
shuttles, and I mount the said parts on the frame of the loom; whereas the only
part or parts remaining attached to the batten are the reed, and, wherever required,
the race-board.
The batten may be arranged to move between fixed guides, or it may be pivoted to
the frame of the loom as usual, and the shuttle-boxes may form a single cell each, or
they may consist in drop-boxes having two or more cells.
In the annexed drawings fig. 1 is a longitudinal section of a loom comprising my
improvement, the batten, which in this case is oscillating, being shown at the back-end
of its course, and a number of parts not involved in the invention being omitted.
Fig. 2 is a portion of the same section with the batten at the fore-end of its course.
Fig. 3 is the front view of a portion of the frame of a loom having a batten
reciprocating between straight guides, one half of the batten only being shown.
Fig. 4 is a plan corresponding to fig. 3, while figs. 5 and 6 are transverse sectional
views, corresponding to the same figure, with the hatten respectively in its extreme
positions backward and forward.

page_text: In the loom represented by figs. 1 and 2 the batten consists in the frame a and the
legs s pivoted at their lower end to the frame f. In the frame a is fixed the reed k.
and the lower bar of the frame a has the extension b, formning the race-board. These
are the only parts attached to the batten. The other parts, otherwise also connected
to the latter and moving therewith, i.e. the shuttle-box or boxes, are secured to or
mounted on the frame of the loon. The figures show drop-boxes A with four cells
movable in stationary guides 9 and mounted on rods, which are operated by
mechanism such as is in common use therefor, and which for this reason is not
represented in the drawing. The shuttle-boxes being thus separated from the batten,
the drivers located within the former are also independent of the batten.
The means
shown by the drawing for actuating the batten consist for each end of the same,
in an eccentric m, an angle lever wand a link e. The eccentrics are so formed
that the batten remains the longest period possible at rest at the back-end of its
stroke in order to leave time for the shuttle to be projected from one shuttle-box
to the other.
According to figs. 3 to 6 the batten consists in the frame a having the projecting
guiding-pieces c with which it slides in the guides d, the said guides being attached to
the frame of the loom. The batten is connected, alike to the one described above, by
links e to the operating mechanism. As in figs. 1 and 2, A are the shuttle-boxes,
and g is the frame within which they move if drop-boxes are employed.
The construction of loon with positively-actuated shuttle has not been illustrated
by drawing; but it will readily be perceived from the foregoing that, in looms of this
kind, the separation of the shuttle-operating parts from the batten may be carried out
in like manner as in looms with flying shuttles.
Looms constructed as described may be operated at a speed considerably greater
than heretofore without being subject to vibrations, and the parts constituting the
batten and its operating mechanism may be made lighter. Besides this, an advantage
accrues from the improvement particularly to looms with positively-actuated shuttles
and rectilinear reciprocating motion of the batten, inasmuch as it allows the stroke of
the batten to be increased without inconvenience. The shed in consequence becomes
larger, and a larger shuttle containing a greater length of weft may be employed, so
that fewer interruptions in the weaving-operation are required for the exchange of
the shuttle-spools. This is of special importance if a thick weft is used.
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 :
In a loom, the construction which consists in mounting the shuttle-boxes for flying
shuttles or the carriers of positively-actuated shuttles on the frame of the loom, while
only the reed and, where required, the race-board are fixed to the batten, substantially
as described.
