fuse J whiclrcoxistitutes the head of the projectile. Between the ring Gl and eac-h of the two illuminating bodies is introduced a centrally arched disk K. These disks are provided in their arched portions with perforations L der rmgscl and to weaken the effect of the' bursting charge upon the illumina masses'to such an extent. that the illuminating masses will not be destroyed by the pressure due to the explosion of the burstving charge. The twoilluminating bodies and the g charge lying 4between them are 'fixed in theprojeetile body through means which enable the fire of tlie bursting charge to gain access to the pou'- of bushings Luand M. Of thes'e'bushings, i
on the other side against. the container B of the lower illuminatingbody, while the other (M) abuts against t-he fuse J and the container B of the upper" illuminating body. The bushings M receive the 'parachutes D and consist cach of'two half cylinders so that after the bursting of .the projectile body, they will. be thrown asunder through the influence of Vce'mtriugal force and release the arachutes.
The mod'e of `operation is .as fo lows.: .The -fire of the igniting charge 2 0f the. time fuse J `will be conducted through the powder vbodies H to the bursting charge G' and communicated through Athe channel g2, to all dies. By the explosion 'of the bursting charge, the projectile body is torn]v asunder, so that" the illuminating bodes will be free. Simultaneously the fire of te'bursting charge is communicated through the perforations k1, f1 and the pQwder `rings q1, to the illuminating masses C, vso that t-hese commence to burn. The
e one side against bushings M\ L are separated by centrifugal" force, and a1 resistance `acts upon the parachutes and unfolds them. The illuminat- .ing-bcdies, lwhile their illuminating/masses burn, fall slowly t`o earth. `In consequence of the weakening of the projectile body A t-hrough'tle `'groove al tlie projectile---body"byV the `bursting charg is facilitated, so that the illiuninatingbodies will be set freeavith certainty. at 4the bursting Apoint 5f' the projectile. InasmuchV as the release of the illuminating bodies is effected bythe splinteringof"the projectile body, the'fp'rojectile body can be constructed the tearing apart of of cast iron. This material is not available for the projectile bodies of illuminating projectiles which are constructed in the form of base chamber shrapuels'since the projectile bodies of such illuminating projectiles must possess great strength in order to insure the expulsion of the illuminating bodies. Thus by the described arrangement admitting of the use of cast iron, the production of luminous projectiles is essentially cheapened. hzloreover, the described projectile, compared with luminous projectiles constructed like a base chamber shrapnel, affords the advantage that at least one (the rear) illuminating body falls to earth from the bursting point of the projectile since its jectile body with theinilluminating massesA presented toward the burstin charge.

An illuminating projectile comprising an easily exploding projectile body, an in-V tcrinediately arranged bursting charge in said projectile body and two parachute illuminating bodies arranged-in said projectile body with their illuminating masses presented toward said bursting charge; protecting disks between the bursting charge and 'each illuminating mass.
3. An illuminating projectile comprising an easily exploding projectile body, an intern'iediately arranged bursting charge in said projectile body and two parachute illuminating bodies arranged in said projectile body with their illuminating masses presented toward said bursting charge lprotecting disks between the bursting charge and each illuminating mass, arched toward the bursting charge to adapt them to resist pressure ofthe latter.
4. An illuminating projectile comprising an easily exploding projectile body, an intermediately arranged bursting charge in said projectile body and two parachute illuminating bodies arranged in said projectile body with their illuminating masses presented toward' said bursting charge; protecting disks between the bursting charge and each illuminating mass, arched toward the bursting charge te adapt them to. resist pressure of the latter and having `perforations in their arched portions. through which fire from the bursting charge may cated to the illuminating masses; -'1 5. An illuminating projectile comprising au easily exploding projectilel body, an'intermcdiately arranged bursting charge in said projectile body and two parachute illuminating bodies arranged in said projectile body with their illuminating massesE presented toward the bursting charge, said projectile body having in its inner cylinder wall,`a groove extending longitudinally and approximately the length thereof.
