AUTOMATIC MACHINE GAGING 



723 



Following each gaging operation the blocks pass between air blast 

 tips A, Fig. 10, and the square tubes B marked 1 to 7 leading to 

 receptacles bearing the same numbers. The electrical contact in each 

 gage, which is closed by a defective block, sets a trip connected to the 

 adjacent air tube so that, as the block passes, the air cock is opened for 

 an instant and the defective block is blown out of the test line into the 

 tube, through which it falls into the proper container. A small air 

 compressor is installed as part of the machine.

The O.K. blocks pass along to the automatic packing attachment E 

 (shown in more detail in Fig. 11), which places 100 of them in a box in 

 layers of five each with cardboard separators between layers. The 

 empty boxes are shown in the magazine F, the separators at G, and 

 the filled boxes emerging at H. 



The feed table shown in Fig. 13 will be placed at the same end of the 

 machine as the packing attachment and the blocks will be carried
