upon the same shaft 9g, the gudgeons of which run in boxes 
in the frame 6e. The arrangement of chains or straps, con- 
necting the slide 5g with the pulley 6g, and the slide or rod 
7g with the pulley 8g, will be recognised as similar to that 
often used for moving the pistons of pumps or fire-engines. 
Upon the shaft 14, which runs in boxes on the frame 6¢e 6e, is 
fixed the heart-wheel 2h. Two pins 3h 3h are fixed to the 
slide or rod 7g, so that their sides are in contact with the heart- 
wheel on opposite sides of the same. Upon the shaft 1h, is fixed 
the pulley 4h, from which a belt passes to the pulley 54 upon the 
shaft 6h. Upon the same shaft 6h, is fixed the pulley 7h, from 
which a belt passes to the pulley 8f, upon the shaft 91; upon which 
shaft 9h is fixed the pulley 14. The shafts 64 and 9h turn in 
boxes fixed to the frame 6e 6e. The pulley 1k is connected by 
a belt with the pulley le, heretofore referred to, upon the drawing- 
frame. It will be seen that there is upon the same shaft with le 
the pulley 9d. From this pulley 9d, a belt passes to and round 
the shaft b. 
To understand the effect of the parts last described, in giving 
an endwise motion to the bobbin, suppose the shaft 6, of the 
drawing-frame, to revolve; its motion will be communicated by 
the belt to the pulley 9d, which will turn the pulley le upon the 
same shaft with it. The rotation of le will give motion to Ih, 
whence, as will be at once perceived, the pulleys 8h, 7h, 5h, and 4h, 
together with the heart-wheel 2h, must all revolve. ‘The revolu- 
tion of the heart-wheel gives a rectilinear alternating motion to the 
rod or slide 7g. This rod or slide, from its connexion with the pul- 
ley 8g, communicates a circular alternating motion to that pulley, 
which motion must likewise be common to the pulley 6g ; and 6 
must communicate a rectilinear alternating motion to the slide 
5g. Itis evident that the motion of 5g will be communicated
