"Application filed March 5, 1909. Serial No. 481,243.
To all 'whom 'it may concern:
Be it known that we, CHARLES V'AN CISE WHEELER and ALEXANDER GEORGE MOKENNA, 'both citizens of the United. States of America, and residents of United States of Ame ica, haveinvented certain new and useful Improvements in .Caps for Armor-Piercing' Projectil'es, of which' the following is a specification accompanied by drawings.
The object of the invention is to reduce and eliminate if possible the liability of de` fiecting a projectile' by the one-sided or -un- L 'even buckling,. crumpling, or deformation at 'impact of the mass of 'the cap between the 'nose of the projectile and the'plate attacked.
In caps thatare prolon ed in front of the nose of the projectile to a ord better c'ontour for fiight or for any other 'reason, and 'particularly in caps that have hollow or chambered 'fore-portions, there is a likelihood of one side of the fore portion of the cap buckling or crushing *before the opposite side and by accumulation of a greater mass on one side. of the axis of the shell nose causing a deflection of the nose. To avoid this we have devised a cap that possesses in Combination with the relatively ductile soft cap characteristics required `to support and faclitate penetration of the nose of the shell the further quality of getting its fore portion out of the Way ofthe'succeeding'portions-of the capand shell' nose. This we have accomplished by making the'cap of two compositions, the rear relatively ductile; and the fore portion preferably i'n theform of a hollow'tip and of and Washington, in the Disportion being of the usual and desirable quality of metal and therefore b portion or tip' needs to be' sufb. 'eently strong n.` Anumber o difserve, for example,x
fcanizedrbb er, or. even tough glass; butso far we prefer to use cast iron. v Upon impact the fore portion,` particularly if hollow that fly out of the path ofthe shell and do not-'tend to deflect it.
and comparatively thin, is. broken into small 'or harmless fra-gments In the aoconpanying drawing We show section a cap comprising the present inventon in its preferred' form.
-P is the shell point, B the rearor main portion of the cap, and H the fore portion of frangibl'e material,
The cap may be securedto the 'the tip or fore portion H* of the cap be secured to the' main 'portion by any suitable means,' that shown being 11'). accordance withshall, and
\or fore portion of material that is relatively t frangible or brittle as compared with the' rear portion, whereby on impact it may be broken and' fly out from between the rear 'portion and the plate struck. A l
v 2. Afcap for armor -pierc'ing projectiles .and of two materials, the fore portion being of relatively frangible material and of hollow form. I .3.-A,cap for armor and of two materials, the fore portion being of relatively frangible material and the rear portion of relativelyv. ductile nateriah for substantal-ly the' purposes set forth.
