INVENT R Jon/v HERMAN UNITED STATES PA ENT, QFFIGE- JOHN HERMAN, DE LOS ANGELES, CALIFORNIA.
PROJECTII'E.
Application filed October 16,
To all wlwmz't may concern:
Be it known that I, JOHN HERMAN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Projectiles, of which the following is a specification.
This invention relates to a projectile.
It is the principal object of this invention to provide a projectile which is so designed as to travel at a sustained velocity with greater accuracy and range uvhen compared with other shapes of bullets using a similar explosive charge and which also has reduced frictional contact with the bore of the gun through which it passes.
Another object is to provide a projectile which is notliable to leave a metal deposit along the bore of the gun and which is provided with means for cleaning and greasing the bore as it passes therealong, and is less expensive in manufacture than most projectiles of the same class.
Other objects :will appear hereinafter.
The invention is illustrated, by way of example, in the accompanying drawings in which:
Figure 1 is a view in side elevation illustrating a cartridge fitted with the projectile ,with which the present invention is concerned.
Fig. 2 is an enlarged view in section and elevation illustrating the projectile and particularly disclosing its bearing sleeve and greasing means.
Fig. 3 is a view in transverse section as seen on the line 33 of Fig. 2 illustrating the relation of the sleeve to the body of the projectile upon which it is mounted.
ferring more particularly to the drawings, 10 indicates a cartridge here shown as of the bottle neck type, and within the outer end of which is positioned a metal projectile 11, with which the present invention is con cerned. This projectile is formed with a conoidal nose 12 and a conoidal base portion 13 of equal dimensions. The apices of these portions are disposed in opposition to each other and along the longitudinal center of the projectile, providing stream lines. The base portion 13 is preferably formed of steel having cylindrical nose stem 14 integral therewith. The cylindrical stem 14 forms an annular shoulder 15 around the equatorial portion of the rojectile and against which a greasing waslier 16 of fibrous mate- Specification of Letters Patent.

rial may be disposed. Thisjwasher is held in place by an anti-friction sleeve 17 through which the stem 1a of the nose extends. It should be noted that the base portion 13 has a slightly smaller diameter than the bearing sleeve 17 The outer surface of this sleeve is shaped to form a continuation of the tapered end of the stem and thus pro duce the conoidal contour as shown in the drawings and identical with the contour of the base portion. The sleeve 17 is formed preferably of an alloy, the proportions of which have been determined by experiment and are approximately seventy-five per cent. copper and twenty-five per cent. lead.
This sleeve will thus allow the projectile to easily pass along the bore of a gun and will not leave a deposit of metal upon the surface of the bore. The fibrous washer 16, if used, has been saturated .with a suitable grease or oil which will be spread along the barrel of the gun as the projectile travels, this being due to the factthat the outer circumference of the washer is forced against the barrel and will thus be forcefully drawn therealong.
In operation, the projectile when fired will pass along the bore of the gun barrel and therefrom. During its movement through the barrel it .will bear with its bearing sleeve along the surface of the bore, thus eliminating friction therebetween and preventing the deposit of metal upon the surface of the bore as the projectile becomes heated. The greasing washer will follow the sleeve and apply lubricant to the surface of the bore. Due to the bullet design the rifling of the gun barrel may be reduced. After the projectile leaves the bore of the gun it will move through the air against the resistance there of. This resistance will be materially decreased due to the formation of the rojectile which eliminates counter-resistance which would retard the projectile. It will also be observed that due to the stream line of the bullet it will tend to point directly along its path of travel.
Attention is directed to the fact that due to the use of a copper sleeve upon the forward end of the projectile the nose of the projectile will be increased in weight over the opposite end and this will tend to prevent the projectile from turning end for end as well as to increase the accuracy of its travel.
It will be thus be seen that the projectile here have an ind-eased t elocity over projectilesrfired with thesame force me, it W111 V changes m the combmatlon, constructlon and and will also ineuretl'iat theba'rrel 'df'the gu u thl ough whlch tamed In a' clean condltion.
