14. inches iquare 5 ; it is worked by. a han- 
diz, on the axis of which a {mall fy. 
wieel is fixed ; itreceivestwo wires at the 
fame time from two barrels or reels, ca 
each of which a coil cf wire is placed ; 
the wircs are drawn forward from thence 
on pe che handle of the machine, they 
pafs through two rollers, and are cut and 
vlouble crvoked as they advance within it : 
the wires, when properly iormed for prick- 
ing into the leathe rs, drop down into a 
receptacle under the machine. —-The ad- 
ventages expected from this inventionare, 
1. The great eae with which the 
great 
extent to which it mzy be employed; 3. 
That it does not wafte wire as other ma- 
chines do, on account of i's feeding itlelt, 
which ts a very material advantage.
