Shaw & Clark 



Figures 53 and 54. — Running-stitch machines were also attempted by several other inventors. Shaw & 

 Clark, manufacturers of chainstitch machines, patented this running-stitch machine on April 21, 1863. 

 From the appearance of the patent model, it was already in commercial production. On May 26, 1863, 

 John D. Dale also received a patent for an improvement related to the method of holding the needle and 

 regulating the stitches in a running-stitch machine. Dale's patent model was a commercial machine. 



John Heberling patented several improvements in 1878 and 1880. His machine, which was a little larger 

 and in appearance resembled a more conventional type of sewing machine, was a commercial success.
