PROJECTILE.

To all whom it may concern J Be it known that I, Josurn BIZAS, a citizen of the United States, residing at Cin-' such as aeroplanes, and airships of the balloon type, and for aerials on'land and on war vessels.

The primary object of the invention is to provide an aerial projectile of this character which is in the form of an elongated body having a plurality of arms normally but which are adapted to be projected radially from the body as the projectile is shot from themuzzle of the gun, so these arms may serve to rake through the framework of an aeroplane,

the antennae of a Wireless aerial, orsome such target in a much more effective man ner than could be accomplished by the usual form of cannon ball or other projectiles'of this type. I

A further object is the provision of a projectile of the class set fort-h which is adapted to contain an explosive, and where in. a. longitudinally movable plunger is mounted for use in locking the raking, arms in their inoperative positions, but which is adapted to be actuated by the initial dis charge-of the projectile, to release the arms before the projectile leaves-the muzzle of the gun. The plunger is adapted to cause ignition of the explosive, when the move ment of the projectile is retarded by impact with the target. Springs are provided for automatically throwing the raking arms into their operative positions when they are released from'engagement with the bore of the piece, it being understood that the latter, must be of the type wherein the bore has rectilinear grooves and lands' Specification of Letters Patent.

, Referring to the drawings by numerals,

l designates the substantially cylindrical body of the projectile which is composed of a plurality of longitudinally extending sections 2, each of which is sector-shaped in transverse section. The narrow inner edges of the body sections are cut away longitudinally throughout a portion of their length to form a long'itudinalmedial bore for a purpose which will be described presently. Trasversely extending bolt members 3 connect the rear ends of the sections 2, each bolt member being extended through two diametrically opposite sections, and. the sections of the body are bound together at this end also by the cap. 4 which is threaded body as at 5. This base cap has a plurality-of compression bands 5 projecting outward from grooves in its outer periphery, and is provided medially thereon with a non-circular projection '6 which is adapted to be engaged by a wrench purpose of ape or otherturning tool for the plying the c'ap to the body, or in'detaching threaded onto the front end of the body as at 8 and hasa squared portion 9 forthe application of a turning tool thereto. The

A pointed cap 7-is.

body sections are constructed preferablyof.

cast iron, Whereas the base and point caps are constructed'of steel.

djacent sections 2 of thebody are provided in their meeting faces with longitudinal recesses-which register with each other to form a slot 10 communicating with the body bore for the reception of movable rakin arm or blade 11, whose rear end is pivotal y connected to the body by .means of the pivot pin 12. These blades 1 1 a radially are constructed preferably of soft steel and have their inner edges sharpened as at 13 so that they will offer a minimum amount of resistance when they are extended from. the body during the flight of the projectile, but

the blades are adapted, when in inoperative position, to be disposed within the respective body slots with, their outer edges flush with the outer periphery of the body.

The pivoted ends of the raking arms are provided rearwardly of the pivots with eyes 14 which are connected by means of short flexible members 15 with the rear end 16 of a helical exten'sile spring 17 which extends longitudinally through the'rearmost portion of the body bore. A cable 18 is connected with the forward end 19 of the said spring and extends forwardly through the body bore to. the tensioning device mounted within the point cap, to the winding drum 20 of which it is connected. The

20 is fixedly mounted, is journaled in bearoperating shaft 21, upon which the drum ings 22, which latter are constructed so as to prevent longitudinal thrust of the shaft,

and extends radially within the cap. One

end of the operating shaft has a non-circular end 23 which is disposed inwardly of the lateral cap opening 24 and is adapt; ed for engagement by a turning key such:

as that indicated by the numeral 25. This key may be inserted through the cap open ing when it is desired to wind the drum,

but must be removed therefrom before the projectile can be used. A ratchet 26 is provided upon the shaft 21 and a pawl 27 is mounted within the cap for engagement with the ratchet to prevent retrograde movement of the'cable after it has been wound upon the drum to place the spring 17 under the desired tension. A spring 28 is adapted to maintain the pawl normally in its operative position in engagement with the k The plunger is provided upon'e'ach corner thereof adjacent to its rear end with an eye 31 for the reception of a longitudinally extending, resilient tongue 32 which is disposed ,within the corresponding body slot and has its rear end connected with the body by means of a pin 33. Each tongue 32 is placed. under lateral tension when brought into its operative position for engagement within the corresponding eye of the plunger whereby it will frictionally engage the eye. An ofi'set portion 34 is formed upon each gongue adjacent to its free end providing 1 miting shoulders 35and 36 for engagement with the eye 31 to prevent ex- .cessive.longitudina1 movement of the plunger under ordinary conditions, such as the handling of the projectile prior to its being placed in active use. These. sustaining tongues are thereforeadapted to yield, when the plunger is moved axially with suflicient force, for purposes which will be described fully hereinafter.

A substantially L-shaped locking member 37 4 is detachably connected with each corner of the plunger adjacent to its front end for movement within the adjacent body slot with its longitudinally extending portion 38 adapted for engagement within an eye 39 v projecting inwardly from the free end of the correspondin raking arm,'when the plunger is in its orwardly disposed locking p0 sition with its eyes 31 in engagement with the shoulders 36 of the sustaining tongues 32, so as to secure the arm in its inoperative position within the body slot against the tension of the spring 17. It should be apparent that, when the plunger 29 is moved rearwardlywithin the body of the projectile with suflicient force, the arms 11 will be released, whereupon they will be thrown into their operative, radially extendingpositions by action of the spring 17. Each arm is adapted, when in operative position, to bear against the shoulder 40 provided at the rear end of the body slot in which the arm is mounted. In order to prevent too forcible impact with this limiting shoulder, a helical extensile spring 41 has oneend connected with a transverse pin 42 provided within the forward portion of each body slot 10 and has its opposite end connected by means of a flexible member 43 with an eye 44 provided medially upon the corresponding arm 11. The flexible member43 is adapted to be drawn taut as the arm assumes its operative position, whereby the spring 41 serves to mitigate'the force of impact with the limiting shoulder. The said spring and flexible member are adapted to lie within the corre sponding body slot when the arm is in its inoperative position, and when the arm is in this position, it is adapted to engage the pin 42, which latter serves to prevent the free end of the arm from projecting too far into the interior of the body.

In the front and rear ends of the projectile body, chambers 45 and 46 respectively are provided for the reception of explosive material. Fuses 47 lead from the explosion chambers 45 axially to the. percussion caps 48 arranged within the forward ends of the respective body slots 10 inthe. paths of movement of the engaging portions 38 of the members 37 carried by the plunger 29. These projecting portions 38 of the members 37 are adapted to detonate the explosives I target. The shoulders 36 of the sustaining body section. Owing to the provision of .a
