Without in any manner inipfing that the carrying on of this process is to in any Way limited to the utilization of any particular mechanism, means or apparatus. we will now describe such snparatus and grouping or assemhlang'e of features and means a .xe-mplified in the accompanying drawings, in which:

Corresponding parts in all the figures are designated by the some reference characters.

The manner of cart-ring on the improved process constituting th invention, with poi ticular reference to the apparatus and group of features and elements shown in the drawing, Will be readily understood from the foregoing description taken in connection with the accompanying; drawings and the following statement.
