an inch, and may be graduated to any length, within that limit 

 by the feed stop, 54, against which the feed bar is thrown by the 

 feed spring, 12. As the widest or the narrowest part of this 

 eccentric stop is turned towards the feed bar, greater or less play 

 is permitted, and longer or shorter stitches are made. This stop 

 is turned with great flicility while the machine is in motion, by 

 the lever with which it is furnished. 



The machine is mounted upon a neat work table, and driven 

 by sandal treadles and band, 1. The fabric to be sewed, 45, is 

 laid upon the cloth plate, 46, beneath the needle, and held by the 

 cloth presser, 20. The threads being adjusted, the machine is 

 touched into motion by a gentle pressure of the foot upon the 

 sandals. The cloth moves forward from left to right, and the 

 sewing is accomplished in the manner above described. There is 

 no limit to the number of stitches that may be made in any given 

 time. The driving wheel is graduated ordinarily so as to make 

 five stitches at each tread, so that from six hundred to one thou- 

 sand stitches per minute are readily made. The bearings and 

 friction surfaces are so slight, that the propelling power required 

 is merely nominal. The rotating hook, feed, bobbin, and other 

 parts at all subject to wear, are made of finely tempered steel; the 

 other parts of the machine are tastefully ornamented or heavily 

 silver plated. 



Various appliances are furnished 



for regulating the width of hems,

guide, 42, is attached to the fixed

 gauge, 58, very commonly used, but not in conjunction with the 

 larger, is fastened to the cloth plate at the screw hole, 44, by the 

 thumb screw, 43. Another appendage is the hemmer, 48. It is 

 used in the place of the cloth presser, 20, and is, in fact, a cloth 

 presser so convoluted, that as the edge of the cloth passes through
