TRANSACTIONS OF THE 

 Tiz. 4. 



As the hook further revolves to the position indicated in fig. 4, 

 both lines of the loop e are upon tlie same side of the hook. The 

 line of thread that extended on fig. 3, along the groove of the hook 

 by b, has slipped off at the termination of this groove, and fallen 

 in front of the bobbin, so that the loop of the thread e extends 

 behind the bobbin, around the point of the hook a, and across the 

 front of the bobbin to the needle 35, thus surrounding the bobbin, 

 and inclosing the lower thread z. The hook further revolving, 

 the loop e slips from the point of the hook, and being drawn up 

 by the enlargement of the succeeding loop, (see fig. 2,) interlocks 

 with the lower thread z in the fabric, and forms a stitch similar 

 to those represented in the several figures above. 



To illustrate more clearly the method of making the stitch by 

 the Wheeler & Wilson madiine, we have exhibited the rotating 

 hook 5 and the bobbin carrying the lower thread, detached from 

 the machine.
