fall, and the ends of the levers Q Q, which pass from the rollers 
to the right in figs. 1 and 2 must be depressed, and the rods 3a, 
the cross-bar 2a, and the rod 1a likewise must drop downwards. 
Now the weight y, acting, through the lever v, upon the slide-bar 
o o, tends constantly to draw the slide-bar to the right, as seen in 
fig. 5; but this tendency is, ordinarily, resisted by the connexion 
of the slide-bar with the spring u, fixed upon the shaft rr, the 
horizontal arm ¢ of which shaft is united by a joint with the rod 
la. When, however, the rod la passes downwards, the arm ¢, 
no longer supported, cannot keep the shaft r 7 and the spring w 
in their former position, but it suffers the weight to carry the 
slide-bar to the right, the slide-bar carrying with it the top of the 
spring uv, which at the same time rolls the shaft r r, depressing 
the arm ¢. When the slide-bar o 0 moves, as herein described, 
to the right, it carries the boxes q q, and likewise the clutch-boxes 
b b’ with it. The clutch-boxes are, by reason of their connexion 
with the shaft ff, as before described, always constrained to 
revolve with the shaft ff, and the catches m and n are, of course, 
carried round with them. If, therefore, the clutch-boxes are 
carried far enough to the right, as seen in fig. 5, the catches m 
and n would strike the pins ’ and k respectively ; but as the pin 
k is longer than k’, and approaches more nearly to the circle de- 
scribed by n, than the pin k’ approaches that described by m, the 
motion of the slide engages n against k, before m can strike Kk’. 
It will be at once perceived, that as soon as nis engaged against 
k, the wheel g will be made to revolve ; this will drive the wheel 
i, by which the pulley 5c must revolve, and the motion of 5c will 
be communicated by its belt to the pulley 6c, and from thence 
through the pinion 8c, the wheel 9c, the pinion 2d, and the wheel 
3d, to the pulley B, by the revolution of which the hatchel-belt 
will be moved and the roving advanced towards the drawing-roll-
