Class Information
Number: 124
Name: Mechanical guns and projectors >
Description: This class includes the various forms of projectile-throwing or impelling apparatus in which the propelling agent is nonexplosive. The apparatus must carry or hold the projectile so that it may be used for aerial projection. This class also includes devices which actually expel the projectile, but have the projectile tethered to the projector to prevent loss of the projectile; and some devices having the structure of projectors, but having means at the end of a barrel to prevent actual expulsion of the projectile.
