Commissioners of Patents, with his Petition; on the 28th October
1859.
I, DEILE DILLIES, of Roubaix, Department du Nord, in the Empire of
France, Manufacturer, do hereby declare the nature of the said Invention
for "INNOVATIONS IN WEAVING LOOMS," to be as follows:-
By certain modifications, easily applicable to power looms, to throw two
shuttles successively from one side, then two from the other side, and so on,
an advantage never hitherto obtained in power looms is the result, namely
weaving "shoot to shoot" (in French, duite à duite,) that is to say, to weave
a shoot or throw of one color, after that one of another color, and so on
successively, and I effect this by constructing the loom as shewn in the
accompanying Drawing, in which 6 shews the main shaft of the loom, receiving
motion from a pinion mounted on the pulley shaft, and gearing in the wheel c;
d, d', excentrics transmitting motion to the lams; e, e¹, vertical shafts, having
at their upper ends the whips or shuttle drivers; f, f', conical pieces, each
one turning freely upon tail pieces g, g', fixed on the shafts e, e¹; h, h', grooved
rollers, forming the ways crossing; j, j', sockets, carrying on one side the
rollers h, h, and on the other the plates a, a¹; k, l, supports, with socket fixed
to the framing; l, l', spindles mounted in the sockets k, k¹, and terminating in
a tail piece, which constantly engages itself in the march of the rollers h, h¹;
a, a', plates, each carrying two cams or lifts, and fixed upon the socket
pieces j, j; m, cam fixed on the shaft b, serving to rise and fall the box n,

which holds the shuttles; n, box with two compartments, holding the shuttles;
P, lever fixed to the box n, and jointed to another lever q, which is fixed on
a longitudinal shaft ; s, lever fixed on the shaft r, and having at its end the
round piece t, which invariably presses against the cam m; r, longitudinal shaft
piece fixed to the framing of the loom. The levers P and 9 are repeated at each
end of the shaft r, because there is a box n on each side of the loom.
two cams on the plates a and a' are for driving the two shuttles successively
from one side while the whip or driver on the other side is in repose; they
should be regulated so as to strike the pieces f, f, when the lams are open.
The roller h, mounted on the socket j, advances or retires when the crossing
of the ways passes before the tail-piece of the spindle 7, and as the plate a,
carrying the cams, is connected with the socket j, it follows, that when the
roller advances, the plate a advances equally. The crossing of the ways of
the rollers h, h', are regulated so as to advance or retire at the same time, so
that when the piece f is working, the piece f¹ is in repose, and vice versa.
Supposing the double box n to be furnished with two shuttles, the one carrying
a green and the other a black spool, the two shuttles leaving successively the
sam box n, one green and one black shoot will be obtained, the same
succeeding from the other side, and thus will be formed mechanically a tissue
known in France as "duite à duite," in English, as shoot to shoot.
