ment in Luminousl Projectiles,iof which the following is a specification.

This invention relates to luminous projectiles and has for its purpose to increase the strength and duration of the illuminating effect of these projectiles.

n the accompanying drawing, one embodiment of the invention is illustrated, and in said drawing Figure 1 is an axial lon i tudinal section of a luminous projecti e; Fig. 2 is a section on thevline 2-2 of Fig. i; and Fig. 3, shows on a small scale a view of an illuminating body with a descending parachute.

The illuminating projectile as is known of illuminating projectiles that receive a large number of ighting bodies, has a constrluctionsimilar to a base chamber schrapne A designates the shell of the Iprojectile, B the base chamber charge, C the driving disk and D the time fuse which with the aid of a front end bushin l?. is connected with the rom the time fuse D, two

re tubes F, .which are located in grooves a (Fig. 2) of the projectile shell, lead to the base chamber charge B. The fire tubes l" stand in communication with the igniting char d of the time fuse, through the medium of bores d of the timefuse and openings e' which are provided in a disk e,

ront end bushing E. Ijhe'projectile space receives two illuminating odies, each of which is provided, iii a known manner, with a parachute L. Each li hting body a lighting mass G, w ich. is located a pot-shaped container H of the interior xrriiameter of the projectile .und is retained in the container H by a cover plate K carrying a bolt J. In the cover plates K, openings`k are provided, which terminate ata ring gl of ressed powder suitable for i iting the illuminating mass and embedd in the illuminating mass G. Bolts J are screwed into the bottoms of the respective containers and 'are formedd outside ofthe container, into a turning stu i* for a swivel h* to which the parachute L is secured. Furthermore, two studs la' are arranged on each'container H which engage in grooves a' (Fig. 2)- of the projectile shell Vwithin the projectile Voccurs in the and prevent turnin f of the illuminating bod in the projecti e shell.

'l ic coiitainei H for the illuminating mass of the lower illuminatin `body rests through its open side immediate y upon the driving disk C. This is provided with recesses for the cover late K :is well as its fastening means, an beneath the openings c with igntinopenings c, so that the fire of the charge can immediately reach the powder ring g of the lower illuminating body. The 'container H of the upper illuminating body supports itself with its base u on two telescoped bushings Mand N, which rest upon the bottom of the container H of the lower .illuminatin body. Upon its open side the container lies a ainst the disk e1 of the front end bushing In the disk e as well as inthe inclosing cover d' for the igniting chare d2 of the time fuse, o enings e are provi which 'the ame of the igniting charge d* can reach the powder ring g of the upper lightin body. V

The ushin M and N receive the aracliutes L 'of t e two lightingI bodies. ach

bushin com rises two half cylinders (F ig.

2), so t at a r ejection of the illuminating body, the will be separated under the in- Huence o centrifugal force' and release the parachute. Between the two parachutes, a disk P is arranged; whichA can be suitably produced from paper or the like. The inner bushing N is-desirable in order to facilitate thelinsertion of the parachute of the up r lighting bodv.

e insertion o the illuminatin body iollowing manner: First, the filled container H of nn illuminating -body is inserted in the projectile shell in. suchl a manner that it rests with its open side upon the driving disk C, whereupon the outer bushing M is set up upon the bottom of the container H and the arachute 'is pressed into the hollow of this. Bushing. The arachute will then fill approximatelv the whole of the bushing M. The disk I is now laid upon the arachute within the bushing M, the inner ushing N is placed upon the rim of the disk P, and the parachute of the second illiuuiniituf.T body is placed in `4the bushing container H of the second illuminati body is laced u on the rim of the bushing N an then with the aid of a press, the bushing N together with the illuminating body ed, through IUI) Then the 'f restinv upon it is pressed into the projectile until tie container H of the u per illuminating body rests upon the bushing M. In accouiplishing this, the rim of the disk P will be crimped downward by the bushing N, and the vbushing N comes to rest upon the bottoni of the under container Il.' Ilie paravhutes are in thisl manner extraordinarily lirmly pressed together, so that the metallic parts (wires) of the paraehutes, when under the iniiuciu-e of theI force of inertia Set up upon tiring the projectile, cannot move and, therefore, caiinotproduce any destruc tion of the material of the parachutes.

The operation of the projectile is as folof the time fuse i nites, immediately, the illuminating mass nii the up er illuminating body and, through thc medium of the fire tubes F, the base chamber charge B. -The latter brings the illuminating mass of the under illuminating body to ignition. After the ignition of the base chamber charge, both illuminating bodies will be ejected through the medium of the drivingr disk C. By this step', the front end bushing E, with the fuse D, separates from the projectile shell. As soon as the illuminating bodies have left. the projectile shell. the bushings M and N are scattered by centrifugalforce. The resistance of the aii -:ien acts upon the para chutes L and uutolds them. The illuminats ing bodies, while their illuminating masses burn, fall slowly, to the earth. After the ex pulsion of the lighting bodies from the projeetile, said bodies together with their parachutes partake of the rotation of the projectile. The speed of the revolution of the illuminating bodies diminishes more slowly4 than that of the (lighter) paracliutes, so that ailative turning between the illiimimating bodies and the paraehutes takes place. This rotation is permittedl by the rotary connection between the lighting body and the parachute, afforded by the swivel h and the stud if', without twisting the cords connecting the parachutes with the illuminating bodies; the unfoldinv of the parachutes will thus 'be insured b their rotatable connections with the luminating bodies.

By the arrangement of the illuminating bodies in such a manner that the illuminating mass of the one illuminating body stands in communication with the igniting charge of the time fuse and the illuminating mass of the other illuminating body stands in communication with the base chamber charge, a more certain ignition of the illuminating masses is obtained. Furthermore, by having the illuminating bodies use the same dimensions as the internal diameter of the pro'ectile as well as by using the described bus ings for releasing the paracliutes instead of space consuming springs, there is attained the advantage of keeping the dimensions of the illuminating mass and the parachutes very large. The illuminating bodies thus possess a stron" illuminating etl'ect with great burning an falling duration.
