/» Mating a Bomb Ttrower 

 for Sham Battles. 



Bv J. S. Zerbe 



MODERN methods of warf;irc 

 have developed, among 

 other things, the throwing 

 of hand grenades, or bombs, — pro- 

 jectiles which are used at close 

 quarters against an enemy's trench 

 and also for the purpose of resisting 

 a rush. The use of this weapon docs 

 not depend so much on the amount 

 of actual damage which it ac- 

 complishes as it does upon the dis- 

 organizing results in the ranks (;f 

 the enemy following the explosion. 

 Many grenades arc now proxidef 

 with chemicals which produce irri- 

 tating or stupefying gases designed 

 to halt a charge or to silence tiie 

 activity of a trench about to be 

 stormed. 



The disadvantages are the inabil- 

 ity of the throwers to propel bombs 

 a sufficient distance to do the most 

 effective work and the inaccuracy 

 of delivering the shots. In action 

 during battle it is difficult to follow 

 up a correctly-put shot with anothir 

 which will be sure to reach the same spot. 



The grenade is a de\ice which can be 

 niade for throwing small projectiles, and 

 in such cases the gear-wheel described 

 need not be used, since speed is not s<j 

 essential. Its use, moreover, will teach 

 important lessons in the trajectory of 

 lirojectiles. 



The device utilizes centrifugal motion 



By means of centrifugal force the apparatus 

 shown above throws bombs a surprisingly long 

 distance. With two such machines, boys can 

 wage battle as long as their ammunition holds out 



and in this respect resembles the action 

 of the arm in throwing an object. Its 

 use in warfare will effect a wonderful 

 change in the handling of this class of 

 projectiles. The drawings above show a 

 side view, Fig. i, and a front view. Fig. 2. 

 A wooden or metallic frame is pro- 

 vided which comprises six posts, a base 

 upon which they are mounted, and three 

 top stringers. Two of these stringers are
