APROJECTILE on HAND-FIREARMS.

Specification of Letters Patent.

Application filed February 20, 1905. Serial No. 246.549.

' Patented Jan. 22, 1907.

To all whom it may concern.-

Be it known that I, ARTHUR GLEINICH, en

gineer, a subject of'the German Emperor, re-

' siding at Friedrichstrasse 3, KonigsNVust-erscribed and claimed and as set out for purhausen, Germany, have invented a new and useful Improved Form of Projectiles for Hand-Firearms, of which the following is a Specification. I

This invention relates to projectiles, and particularly those designed for use in smallarms at high pressures and great velocities.

Heretofore the search for an ideal projectile has not been merely a matter of mathematical calculation based upon ballistic principles, but rathera succession of experiments upon theoretical lines suggested by such calculations, the reason being that the action of the projectile in flight is modified by many extraneous forcessuch as the resistance of the air, the head-wave, suction,.&c.all of.

which influence and are influenced in a varying degree by the constantly-changing velocity of the projectile.

Recent researches by photography of flying rojectiles, according to known methods, at ifferent velocities serve to indicate the pointed nose as productive of the most desirable form of head-wave for projectiles at high velocities; but any conclusions based hereon have been and must be qualified by'other requirements and conditions present as to course of fiight, range, penetration, stop ing effect, &c., and these are onl satisfied b a proper combination of body imensions, is-

tribution of mass, and form of body and head.

I have as a result of extensive research and experimentascertained that the projectile est meeting all requirements of a small-arm shootin 'at high velocitiessay in excess of five hundred meters per secondis that forming the subject of my present invention, as hereinafter more partlcularly deoses of illustration in the accompanying rawing.

As will be seen by an inspection of the drawing, the new projectile consists of two partsthe c lindrical body or guide partl and the hea s, the lines of which latter are curved upon a fixed radius 1. Each of these Taking the caliber of the gun or the diameter (1 of the projectile-body as'unitythe dimensions of a form may be given as follows: len th of body I, 1.85;-1ength ofhead s, 2.19; ra ilis of curvature of head-134. 7 to 8.2 radius of-curva ture of nose-point, .5 millimeters The dimensions given are those found to be best adapted for general requirements; but some deviations are permissible and may, to meet special conditions, be desirable. Such deviatlon's, however, should, to obtain the best results, be within the following limits, again taking the caliber as unity: for the length of body Z, .60; for the length of head 8', ..46 or '37. A projectile constructed according to these relative dimensions is found to possess a capacity for speed of flight in excess of the ordinary projectile, reat penetra' tion, superior stopping effect, at trajectory, accuracy, and extended range.

Having fully described my invention, what projectile of my preferred substantially one-half the total length of the projectile and curved upon a radius of four to nine fold the caliber, and having its other dimensions substantially as set forth.

4. A projectile having a' body part substantially 1.85 calibers in length, anda pointed head substantiall 2.19 calibers long, and

having its other imensions substantially as.

set forth. v

5. A projectile havinga body part substantially 1. calibers in length, and a pointed head substantially 2:19 calibers lon the lines of the pointed head being curved upon a radius of from 4.7 tov 8.2 calibers. 6. A projectile having a body part substancurved uponand the tially 1.85 calibers in length, and a pointed name to this specification in the presence of head substantially 2.19 ca'libers long, lines of the Ointed head bein a radius of 0m 4.7 to 8.2 cafibers, 5 head terminating in a oint curved upo radius of substantially millimeters.

In testimony whereof I have signed the two subscribing Witnesses.

ARTHUR GLEINICH.
