3687 Mr. Treadwell’s Description of a Machine, 
to the spindle 3f, the bobbin 5f, the pulley 6f, and the bar 4f, 
which forms one of the boxes in which the spindle revolves. 
The belt which passes from the pulley 6f to the drum 9f, will, 
during this endwise or rectilinear alternating motion of the bob- 
bin, pass along over the bodies of the drum 9f, and the binder- 
pulley 2g. To persons acquainted with spinning-machinery, 
there will probably appear an unnecessary minuteness of detail 
in this and some other parts of the description of operations, 
which are similar to those of the common spinning-frame. My 
excuse must be, that a mere indication of parts and motions 
would not enable one unacquainted with the common process of 
spinning to understand this machine. 
There remains to be described only the apparatus by which 
the motion of the machine is destroyed whenever the thread or 
yarn is from any cause broken. The first part of this is called 
the stopping-guide, and is seen on the drawing-frame marked 2e 
2e, in figs. land 2. Itisa rod of iron, hung by a hinge-joint at one 
end to the frame 4.4, &c. From the end which forms the joint, 
the rod passes horizontally towards the bobbin-frame ; when it 
reaches nearly to that frame, it is bent so as to pass directly under 
the filament or yarn, where it is under the operation of twisting ; 
from this it is again bent upwards so as to form a sort of hook 
which lies against the side of the yarn, as seen in fig. 1. Upon 
one side of the rod thus described is riveted a piece of iron, 
forming a forked guide, as seen in fig. 2; and through this fork, 
as here seen, the main belt, by which the machine is driven, passes 
from a drum above, to the pulley a. To the end of the stopping- 
guide, next to the bobbin-frame, is fixed a cord which passes 
from it to and over the sheave or pulley 4e placed upon the 
bobbin-frame, seen in fig. 16; and to the end of this cord a small 
weight is attached.
