SYMBOLIC NOMENCLATURE OF OBJECTS PERTAINING TO STAPLE 



MANUFACTURES. 



Definitions. 



1. A staple product or staple is one of the principal productions 

 of a given workshop, concerning which in all its parts definite 

 economical information is wanted. 



It comprises all the parts needed for a complete mechanical 

 contrivance, assembled, and generally boxed ready for shipment. 

 Examples : 



A carriage complete. 



A set of harness, packed. 



Muskets, cartridges, etc., packed. 



2. A piece is that portion of a staple product which is not 

 meant to be taken apart by ordinary means. 



Examples : 



Each spoke, or the tire of a wheel. 



Each link of a chain. 



Two or more elementary pieces united, as by welding or riveting, 

 become a new piece. 

 Example : 



A section of chain. 



3. A component is a simple mechanical instrument formed by 

 combining pieces in such a manner as to be easily taken apart. 



Examples : 



The felloes of a wheel united to form a rolling rim. 

 The sections of a patent hub, united to serve in distributing 

 weight to the rim. 



4. A member is similarly formed by combining components 

 for the accomplishment of a definite mechanical purpose. 



Examples : 



The wheel for diminishing friction. 



The pole for directing the vehicle. 



The lock of a gun for firing the charge. 



The barrel of a gun for containing and directing the discharge. 



The box for containing the other parts united.
