Be.1t known that I, RICHARD LEHMANN, a

subject of the German Emperor, and resid-' mg at 140 lm'alidenstrasse, Berlin, Germany, have inventedcertam new and useful Improvements in Aerial Projectiles, \of which -the following is a specification.

This invention relates to an' improved aerial projectile having supporting and steeringsurfaces which enable the pr jectile to make a soaring flight whereby the flight of the projectile is increased and the force projecting the projectile is diminished.

i The im roveduprojectile has" a. tubular and as a. guide in being;discharged; it is adapted to be slipped over a rod or spindle for aiming. I

The improved projectile is adapted for use as a to When-constructedfor use as a toy for children, the body of the projectile is made hollow for slipping over a blow pipe for the purpose of a form tie improved last of air.- In this projectile is preferably provided at the front end ofits body with a Wei ht for the purpose of imparting the desire d-acceleration to the projectile and of preventing the latter from turning or tipping u or down. Rotation of the projecti e on its longitudinal axis may be prevented very simply by ongitudinal side steering. surfaces on the body. 4

One form of the improved projectile is illustrated in a diagrammatic. perspective view in the accompanying drawing.

'the form of a. shar c is a blow ife over which the tubular elongated body, ed,-to be slipped for the purpose of 'rojeotion. The body, (1, is provided with ateral steerin surfaces, a and a.
