n8 PROPOSED SYSTEM, 



then turning. We also aim to place the heaviest and most im- 

 portant pieces first. Between each group we " gap " the numbers. 



Regarding position in naming pieces, we assume a front to the 

 machine (where the operator is most likely to be placed), and 

 define direction tersely as "forward," "back," "right," "left," 

 " down," " up." The adjectives of position prefixed to piece 

 names are, of course, derived from these words, as " upper," 

 " lower," etc. A perpendicular row of similar pieces, say 5, would 

 be rated upper, second, third, fourth and lower. A number of 

 different-sized pieces of similar name may, in like manner, be 

 prefixed smallest, second, third, etc. 



Before closing, a brief reference to certain (two) supplementary 

 symbols may not be out of place. One is a small letter after a 

 piece symbol (as FPL-2i-a), signifying that the piece is obsolete, 

 the standard FPL-2I having been altered. After a second alter- 

 ation, the last obsolete piece would be suffixed " b," and so on. 

 Thus duplicate pieces of old-style machines can be identified and 

 supplied to customers. The other symbol referred to is to indicate 

 the number of the operation in the construction of a piece, and is 

 written thus: FPL-2i-ist, FPL-2i-2d, etc. Its use is of great 

 value on detail drawings, time cards and cost records.

SYMBOLIC NOMENCLATURE OF " OBJECTS." 



In order to test the correctness of the principles above enun- 

 ciated, and to illustrate their meaning, they are applied in detail 

 to the most complex cases with which I am familiar ; viz., the 

 manufacture of small arms and of metallic ammunition. For a 

 general application of symbols see the end of this chapter.
