LOOM AND SPINDLE—HOOPER. 653° 
one, D D, which hangs across the loom below the heddles and above 
the treadles, which are lettered E. 
It will now be seen that if any one or more of the long levers be 
tied to any one of the treadles, the -weaver sitting in the loom has 
only to select and press a treadle in order to raise any arranged com- 
bination of warp threads for the weft to pass under as it is carried 
by the shuttle through the opened shed.

Fic. 38.—Shedding motions. 
The character of the shed made by this motion is shown above. 
The horizontal line is the normal position of the warp. The opening 
is made by raising certain selected threads. 
An examination of the section below No. 2 will show that in it not 
only are certain threads of the warp raised, but all others are lowered, 
and the horizontal line of warp has disappeared. This is effected by 
adding to the motion another set of short levers, marked “ F,” be- 
tween the long ones and the heddles, and connecting the lower shafts 
of the heddles with them after removing the weights. If, now, for 
example, the first thread be required to rise and the second, third, 
and fourth threads to sink, the first treadle will be tied to the first 
long lever, and also to the second, third, and fourth short levers. 
The result of this will be that when the treadle is depressed the first
