as it goes to fasten the dots upon the tulle which is passing along
underneath the channel, D. The punching is done primarily and
principally by pressure, but, in order to facilitate the complete
detachment of filaments which might retain the punched-out piece, the
punch is likewise given at the same time a slight rotary motion, thus
imitating mechanically what is performed by hand in the maneuver of all
punches. This rotary motion is communicated to the punches by means of
levers actuated by an eccentric, E, and which move the frame, _h_, whose
bars engage with the horizontal lever, _g_, soldered to the tube, _d_,
thus causing the latter at the very moment the punch descends to revolve
from right to left. The forty punches in operation cause the frame to
return to its initial position through the action of the springs, _b'_.
We say forty, since the inventor, in principle, has admitted 80 punches,
operating 40 as odd and 40 as even; obtaining in this way a dotting in
a regular quincunx of one yard, that is to say, 80 dots arranged in two
rows on a fabric 31 inches wide. But it is evident that a much larger
quincunx may be had by putting in play only a half, a third, or a
fourth of the punches, and causing the tulle and velvet to advance
proportionally. For this purpose it is only necessary to unscrew the
punches which are not to act, and to substitute for the ratchet wheel
which controls the unrolling of the I tulle, another having a number of
teeth proportioned to the desired spacing of the dots.

The punching having been executed, and the drum, A, continuing to
revolve, the punches rise a little owing to the conformation of the
cam-wheel, and through the action of the springs, _b_, and allow the
moistener to move forward to dampen the little circles which remain at
the orifice of the punches. The moistener or dampener is a sort of pad
equal in length to the field of action of the punches, and is affixed
to a cross-bar, F, which is connected at its two extremities with the
