A vehicle equipped with square wheels of the type contemplated by my invention gives better traction and a smoother ride when used on rough terrain than one having circular wheels. Following are the reasons: the sides of a square wheel constitute large flat surfaces for bridging ruts and cavities in the ground whereas a circular wheel follows the surface of the ground and enters many ruts; and the sides of a square wheel provide a large contacting area with the ground when they lie parallel thereto, and, hence, afford better pushing effect, whereas a round wheel affords only a small pushing area, which often results in causing a digging effect.

The invention relates to a projectile that is adapted to produce frightening noises while in flight, whereby such alien sounds will have a terrrifying effect on people nearby.

The psychological effects of weird or unexpected noises, which accompany an artillery projectile or missile, have been explored in many ways, prior to this invention, with minimum results. The Germans, in World War II, attached a noise producing device to aerial bombs, somewhat similar in construction to the organ pipe. A high pitched noise was created. This could be used only on large bombs and was too massive for use on artillery projectiles...

The insufficiencies of the prior art are overcome by the noisemaking adapter of the instant invention. The adapter ring is so designed that they attach to an existant missile without requiring modification of said missile. Centrifugal force, as a result of the spinning motion of the missile after being fired, causes the noisemaking arms or fins to extend and to produce weird, alien sounds of such magnitude as to be heard over a substantial area. The psychological effect, to create panic to those in the vicinity, is thus effected.
