234 REPORT OF 'NHE COMMISSIONER OF AGRICULTURE. 
a. The oblong water-baSin heated by a charcoal-furnace or by steam, — 
and frequently ‘divided by ,vartitions. 
bb. Hooked wires or eyekts to guide several threads and keep them 
apart. 
fe c. Points where the threads are twisted upon each other to clean 
their surfaces and compactly rouud them. 
d. Cylinder on shaft, with a spiral groove in its surface, in whieh fits 
a pin from the traversing- bar, thus giving the lateral movement to the 
thread which goes through a ‘guider on the front end of the bar, which 
moves through the are of a circle. 
e. The reel. 
f. Pulleys which transmit by a belt the rotary motion of the cylinder 
d to the reel ¢, that connected with the reel being the smaller of the 
two. 
g. Friction lever, for tightening or slackening the endless cord, in set- 
ting or stopping the winding operation. There is usually a series of 
such reels in one apartment, driven by the same motive power, but 
each of them, as has been shown, can be stopped at pleasure. In ease 
the reels are driven by a steam-engine, stopeocks and pipes are so ar- 
ranged that the water in every basin can be instantly or gradually heated 
by steam If desired to run the reel by hand, a handle can be placed 
upon the shaft of the cylinder d, or of the reel e. 
Pl. U, Fig. 2, represents a hand-reel, of much the same style as the 
last, set up and ready for work. This machine was illustrated in the 
American Artisan for February, 1874, in the course of an article by W. 
V. Andrews, of Brooklyn. It is as good a hand-reel as is now in use, 
though it is made on the same prineiple as the old French reel of forty 
years ago. 
a. Tin basin with copper bottom for holding the water in which the 
cocoons are boiled, fitting tightly over the tray b. 
b. Square tin tray for reception of cocoons, &e. 
c. Short stick inserted in a holder, on which the ends of the cocoons 
are wound, so as to be ready for use. 
e. Cock to let off water from the basin. This should be done every 
night after use. 
J. Door of furnace lined with fire-bricks, wherein the chareoal fire is 
lighted to heat the water in a. 
g. Flue-pipe to carry off fumes; this, as supplied, is short; the length 
and direction in which it may be carried varying in every ease. It is 
necessary that all the charcoal fumes should be earried. either into a 
chimney or into the open air. 
hh. Glass eyes on wire holders, through which the threads from the 
cocoons pass upward to the pulleys atk. itis ef importance that the 
glass eyes should be so placed that the threads pass upward in a straight 
line from the water to the pulleys at k, and aiso from the pulleys to the 
top of the wheel at 0 (except so far as when diverted laterally by the long 
guider at ll); friction is thus reduced to a minimum, and the elasticity of 
the thread preserved. 
4. A former arrangement for twisting the threads one upen the other; 
this is now discontinued as unnecessary, since the twist given to the 
threads at & and continued downward to the point ’ effects its purpose 
with a minimum of friction, and produces a superior thread. ‘This twist 
is effected by the very simple method of passing one thread round the 
other, as shown in the small drawing of the pulley /. 
kk. Rollers or pulleys revolving on bent-wire stands, over which the 
threads pass.
