the catch 7 falls into the notch g’ of the segment p’, after which the faller 
follows the motion given to the roller w’ by its sliding on the railg. At 
the time, however, that the catch falls into the notch, the lever 1, which had 
been resting upon the boss of the curved arm s’ (jigs. 8 and 15), falls also, 
and takes away the catch which had suspended the latch of the left hand 
end of the balance-lever s', and makes this end to fall a second time, after 
which the rod w” lets another detent of plate s” escape, and causes the shaft 
6 to revolve through the third quadrant, by which the straps p and pb’ are 
brought back to their former positions. Meanwhile the shafts is shifted 
with its wheel 17 into gear with 19, as will presently be described, and the 
eccentric g" (jig. 8) has shifted the wheel 12 into gear with 13, which is 
fixed on a shaft with the scroll r, by which the carriage is now returned 
towards the roller-beam, whilst the winding-on is performed by the drum 9 
( fig. 12), turned by the chain attached to the nut 10 at the quadrant p 
(jig. 8). Round this drum there are a few coils of a rope, which passes 
over the two pulleys 6’” and ¢’” (fig. 8), and suspends a weight, d@'”, in order 
to keep the chain tight upon the drum o. 
When the carriage comes home to its place, near the roller-beam, it 
presses down the right hand end of the balance-beam s, and makes the rod 
w'’ to fall off from the third escapement of the plate s’’, after which the shaft 
6 turns through the fourth quadrant. 
By this motion the eccentric g’ shifts the wheel 12 out of gear with 13, 
while the eccentric m’’ sets the rollers in gear by the coupling upon the 
shaft 7, and of course, also, the drum rE which moves out the carriage by 
the wheels 8 and 9. The bar 7 (jig. 14) has now lifted the catch 7’, out of 
the notch g' in the segment p’, and thus has disengaged the faller shaft; 
finally, the shaft s (jig. 12) is shifted together with its wheel, 17, to give 
twist again to the yarn spun during the next stretch of the carriage. It 
remains only to mention how this shifting of the shaft, s, is performed, at 
the moment of the carriage goimg in and out. The step-bearing of the 
said shaft is fixed on the end of a bell-crank lever, e’” (jig. 8), the other end 
of which is connected with an arm upon a shaft upon which is a kind of 
balance lever, 2’’ and 2’, which passes, when the carriage arrives at each 
end of its course, under rollers attached to the large radial weights u at 
each end of the frame, which thus presses on that one of the arms A/” or 2”, 
which is just arrested by a detent or click, and keeps the wheel 17 in gear 
with either 18 or 19. When the carriage is drawn out, and the wheel 17 
is still in gear with 18, the arm /’” is suspended, and remains so, till by 
the falling of the lever 1, the balance lever s’ makes its second fall, and 
disengages the click by which the arm, 4’, is suspended; the latter is now 
depressed by the radial weight v, whilst the other arm, 7”, is caught by 
another click. On the contrary, when the carriage arrives near the roller- 
beam at the same time that it depresses the balance-beam s, and changes 
the motion, the click which keeps the arm, ¢’’, suspended is also disen- 
gaged, and the radial weight on the right hand of the machine (jig. 8) 
presses down the arm 7’, whilst 2’ is caught in its click, and keeps the 
wheel 17 in gear with wheel 18. %'” is a detent or click, in which an arm,
