368 Mr. Treadwell’s Description of a Machine, 
frame. Figs. 14 and 15 may appear as continuations of figs. 1 
and 2. I have however marked them as distinct figures in ac- 
cordance with the division adopted for describing the whole 
machine. The wooden frame of the bobbin-frame is represented 
at 6e Ge 6e, &c. Across this, near its bottom, passes the shaft 
7e, having its ends, placed in proper boxes, upon the frame 6¢ 6e, 
&c. Upon the shaft 7e is fixed the cone-pulley 8e, which is 
driven by a cross-belt running from the cone-pulley 7d upon the 
drawing-frame. There is, moreover, upon the shaft 7e the bevel- 
geer wheel 9e. The flyer is shown at If 1f, &c., its gudgeons, 
both of which are hollow, running in proper boxes in the frame 
Ge, &c. 2f2f are sheaves or pulleys over which the yarn runs 
to be wound upon the bobbin. The bobbin-spindle 3/ runs in a 
box upon the frame Ge 6e, and in a bar, marked 4/, which is 
placed upon the bars of the flyer, and crosses from one side to 
the other of the same, and is capable of sliding upon those bars 
in the direction of their length. It will be understood that the 
spindle passes through the hollow centre of the right gudgeon of 
the flyer, as seen in fig. 14; the hole through the gudgeon being 
somewhat larger than the spindle. 5fis the bobbin placed upon 
the spindle and kept in place by a pin which passes through an 
ear, or small piece of iron, which is fixed to the bobbin, and 
likewise through the spindle. The pulley 6fis fixed to the bob- 
bin-spindle, and-the pulley 7/f is fixed to the flyer. The drum 9f 
has its gudgeons placed in proper boxes fixed to the frame 6e 6e. 
The bevel-wheel 1g is fixed upon the shaft of this drum, and 
being driven by the bevel-wheel 9e, causes the drum to revolve. 
A belt passes from the drum 9f to the pulley 6f, and another 
belt from the same drum, to the pulley 7f The binder-pulley 
2¢ rests upon the belt which passes from the drum to the pulley 
6f, for the purpose of keeping that belt at a proper degree of
