Pieces for printing by machine are stitched together end to end, -nhich is usually doneby girls, but the use of stitching machines is rapidly becoming general, and probably willsoon become universal. One of these machines, found advantageous, is shown in_^^. 119. 119. This machine was the invention of Charles Morey, in 1849. A pair of wheels are fittedwith leaves on their peripheries, and gear into one another like cog-wheels. These wheelsare mounted in suitable bearings fixed to a sole plate, and receive rotary motion by meansof a winch-handle. The centre of the teeth of both wheels is cut away, so as to form a cir-cular groove between the two teeth which happen to be together. Opposite to this groove,and attached to the frame, there is a bracket which carries ii sliding piece, with a spiralspring wrapped around it. In the end of the sliding piece, which passes through the bracket,there is a receptacle for the eye end of a needle, the point of which rests in the grooveformed by the wheel; the needle is threaded, and the fabric to be stitched placed behindthe wheels, to which rotary motion is coninumicatcd, whurcby the faljric is successivelyfolded into undulations, which, as the operation proceeds, arc forced on the point of theneedle ; when the n
