352 Mr. Treadwell’s Description of « Machine, 
the points. Before fixing the pins to the hatchel-plate, a second 
plate of iron, a fig. 6, and jig. 8, pierced with nine holes, at 
distances corresponding with the points and pins, is placed upon 
the points, the pins are then put in their place and riveted to the 
hatchel-plate. This plate x is called the clearer and can be 
moved freely up and down upon the points and pins, the pin- 
heads preventing it from falling off or being removed; itis longer 
than the hatchel-plate, over which its ends project, as seen in 
fig. 8. A strap of leather, or of strong webbing, three inches and 
a quarter wide, and long enough to form a belt about the 
pulleys B B’, is pierced with holes in rows crosswise, each row 
having five holes at distances equal to those of the five mid- 
dle pins, fig. 6. The cross rows are distant from each other 
seven eighths of an inch, and the holes do not form perfect 
rows lengthwise, but they are arranged as seen at the white 
spots C CC, fig. 2. The strap thus pierced is passed between the 
clearer and the points, the clearer being raised as seen in fig. 6, 
and the points are inserted in a row of holes. ‘This operation is 
repeated until all the holes are filled, and the strap is then pressed 
down upon the hatchel-plate. In filling the strap the rows of 
points are turned so that the wide space between the first and 
second points, fig. 6, shall be to the right and left alternately in 
the successive rows. Another strap, of like dimensions with 
that just described, but not pierced, is then laid upon a table, 
and the strap containing the rows of points is placed direct- 
ly over it, the points being upwards. ‘Two rivets are then fixed 
between every two rows of points, through both straps. The 
straps, with the points thus fixed to them, are then passed round 
the pulleys B B’, and, the ends being fastened together, they form 
the hatchel-belt as seen at CC, &c. As the hatchel-belt is liable 
to stretch by use, the binder pulley D is required to keep it to a
