In its upward movement the shim is carried into a position in which it clears the cylindrical portion of the stud I2 but is still con trolled in its movement by the rib formed in the upper end of the stud. As the feeder 24 is now ' moved toward the left it encounters the open end of the shim I5 and ejects it at the left end of the magazine as shown in Fig. 6. The ejection of the shim of course immediately releases the second blade in the stack so that it is elevated into con tact with the flanges 2| and 22 (with a second shim beneath its end) in readiness to be ejected from the right-hand end of the magazine by the next movement of the feeder toward the right.

For example, in Fig. 3 the blade and lies in position to abut against its left feed slide 24 has completed its movement toward hand end.
