of the Commissioners of Patents, with his Petition, on the 2nd April
1867. A communication from abroad by Jean Baptiste Augustin
Payen-Baudouin, Manufacturer, of 29, Boulevart St. Martin, Paris.
I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING FIGURED FABRICS," to be
as follows:-
This Invention relates to improvements in the battens of looms for weaving
figured fabrics, especially figured muslins.
The object of this improved batten, which is furnished with movable shuttle
boxes, is to effect a saving of a part of the figured weft which is usually wasted
more or less according to the nature of the design; this improved shuttle box
has an opening at each end for the passage of the shuttle in both directions. The
movable shuttle box operates above the warp by means of slides made in
uprights fixed to the bar supporting the upper part of the reed or comb.
The upward and downward movements of the shuttle boxes is governed by.
jacquard mechanism. In this movable shuttle box there is a picker which
closes the box at the opposite end to that at which the shuttle enters, and
which provents the latter passing beyond. Pickers which I term "travelling
pickers" traverse the upper bar, thoir object being to act on the picker in the
shuttle box, when the latter is lowered they pass on the other hand into a
groove made in the picker, when the shuttle box is again raised and is.not
required to operato. This improved batten with movable shuttle boxes

page_text: is applicable for weaving all kinds of figured fabrics in order to economizo the
figured weft, the dimensions being varied according to the width and kind of
fabric to be manufactured while several shuttle boxes may be applied to the
same batten.
In order to render the Invention better understood I have represented in the
accompanying Drawings several of these improved battens and movable shuttle
boxes.
Sheet 1 shows different views of a batten provided with a movable shuttle
box.
Sheet 2 represents two modifications of the same batten.
Figure 1 shows a front view of the batten provided with a movable shuttle
box. Figure 2 is a plan of the same. Figure 3 is a back view of the movable
shuttle box. Figure 4 is a section of the box on the line A, B, Figure 2.
Figure 5 is a front view of the first modification in the arrangement of the
movable shuttle box. Figure 6 is a plan, and Figure 7 a transverse section of
the box represented at Figure 5. Figure 8 is a front view of a second modification
of a batten with movable shuttle boxes; this second modification relates only to
a change in the manner of operating the travelling pickers. The same letters of
reference indicate like parts where they recur.
I will first describe the batten represented in Sheet 1. a, front view of the
movable shuttle box which operates above the warp; b, picker operating in
the movable shuttle box, and set in motion by the travelling pickers c
which effect its displacement as required; d, supports fixed to the bar e
carrying the metal rods h, upon which work the travelling pickers c; e, bar
to which the comb is fixed at the upper part; f, hand hold by which to move
the batten; g, g, brackets fixed to the box a having at their upper parts
screws g', the contact of which with the part f regulates and limits the motion
of the shuttle box; h, metal rods upon which slide the travelling pickers c;
i, metal rods upon which the picker b works; j, guides fixed to the bar e in
which the slides m work; k, supports fixed to the front of the box a, in which
are mounted the rods i; 1, plate projecting into the movable shuttle box,
widened at its extremities in order to prevent the shuttle turning on entering
the box; n, metal bottom of the shuttle box, it is turned up at right angles at o
to protect the reed v from contact with the shuttle, and also to prevent the
latter from leaving the box; p, spaces made in the front a of the box to allow of
producing the necessary tension of the weft; r, levers operating the travelling
pickers c by means of the handle y and cords s; t, cords fixed to eyes on the
movable shuttle box a, and serving to produce its upward and downward move-
ments. These several movements are governed by the jacquard mechanism;

box working beyond the warp; x, batten; y, handle operating the movable
pickers c and the pickers of the boxes w.
I will now describe the modifications of the batten represented in Sheet 2.
Figures 5, 6, and 7 show a modified batten with movable shuttle boxes in
position for operating.
The modifications made in the batten consist, 1st, in the adaptation of a
spring of to the return piece o seen separately at Figure 9, the object of which is
to retain the shuttle in the box by its pressure. 2ndly, in raising the position of
the spaces pin the front of the box a to permit of the tension of the warp. The
raising of these spaces p gives increased strength to the motal bottom n and box a.
3rdly, the picker b which works in the movable shuttle box is the same as before.
4thly, the box is suspended at its upper part by means of hinges a¹ to a metal
part a which slides in vertical guides j¹ fixed to the bar e, and permitting of
the several upward and downward movements of the said box. The picker b
is operated by the rods ³, as seen in Figure 8. The box may also be operated
either, 1st, by fixing the iron plate a" in the guides j¹ so that it cannot act ;
or, 2ndly, by attaching the hinges a' directly to the front of the bar e and on
the top of the box. By these several means the box is worked by a rocking
motion in such manner that the under part is presented to the workman while
the rods, see Figure 8, pass under the back of the box which is then turned
downwards. For this purpose I mount a small balance lever in front of the box,
to the upper part of which a cord is attached passing over a small pulley
fixed behind the bar e, the motion is imparted by the jacquard, which thus
operates the rocking movement of the box.
Figure 8 shows a front view of an improved arrangement of the batten with a
movable shuttle box. The modification consists in dispensing with the levers 7, 1,
Figure 1, which are replaced by an improved arrangement of levers 1, 1, 1, 1ª,
serving to give motion at same time to picker and "travelling" pickers c;
spiral or other springs are mounted on the frame of the batten to withdraw
the pickers and c when they are no longer required to operate.
dimensions and number of the shuttle boxes may be varied as required.
