Application filed June Zilli, '1.905I` Serial No. 266,758.

; and; .State of New York, lhave invented .an

Improvement in Pyrotechnic Devices, of which the following is a speciiication.

My invention relates y to pyroitechnic ,devices yin the nature of rockets and bombs.

Heretofore .the spectaclrlar stream of fire or incandescent particles, asa tail, left the' rocket .in its ascent and the roar or noise thereof have given pleasure and satisfaction to spectators, but thefalling sticks of rockets ossess `an v-element of danger to .be avoided. ith bombs fired from a :mortar lthe eXplosi'onvof the fire .charge is manifest, but nothing is 4again heard until ,the explosion in midair, .or visible until .the Icolored stars .are .as the result of the explosion fired, released, and scattered, there being no element of danger from the bomb as ythe v`paper particles of the same lare blown to atoms., f

Thefobject of my invention -is the construction. of aboI-nlb yhaving arocketeii'ect-that is., with a tailof lire like the tail of the rocketso that `there will be .a spectacular effect during theascentof the bomb similar vto the effect of the rocket.

In carrying out my invention ythe bomb is provided with a tubular ,portion and heads, between which is placed the igniting .and burstingcharge .of ,powderand series of disks of pyrotechnic material forming Athe stars whenignited. Adjacent to and outside of one hea-d is placed the firing-powder char e, and through the op osite head is a `tubular body, preferably ofp paper, for the igniting time-fuse, which 1communicates with the igniting and bursting `charge of powder within the bomb. Around t'his .tubular body is .an annulus of pyrotechnic material preferably in a solid form, and within the .tubular body adjacent to the' outer end and ,in proximity with the time-fuse is also preferably placed aquantity of the same material for .producing the tail of iire when Klighted duringthe ascent ofthe bombso as to give to the bomb :a rocket eifect. This pyrotechnic material and the firing-powder charge at one end of the bomb .are simultaneously ignited by means of .a quick-fuse or quick-match, as hereinafter described. As the bomb leaves the mortar and ascends in mid --air the lighted pyrotechnic material burns with all the visible scintillating.effeettofan.ascending rocket, a .tailfof fire vbeing left behind.

My .invention lis applicable to any form .of bomb. y

lfn the drawings, Figure l Ais a verticallongitudinal section of va bomb made according to my invention and an lelevati-on of the quick match or fuse. Fig. 2 is a sectional plan of thesame at ma; of Fig. .1.; and Fi'g. .3 a

sectional plan at `y y, Fig. l'.

The bomb is referably ycircula-r .an'd\comprises the disk; eads a b and .cylindrical intervening shellxc, which ,parts .are preferably formed'ofpa erin thenature of strawboardf, the cylindrical' shell' c :being preferably wound as a tube-section and the .diskeheads a b of a diameter agreeing therewith and' iitting over the ends thereof. These parts are held together a surface of paper, Vpreferabl-y pasted thereto. At `one .end- .di represents the charge of firing-'powderl `ignited after the bomb is ut in the l.mortar .and :employed for propel ing the' bomb, the bei@ t of which Athe same 4is forced `bei1ig`.co1it'rol: ed by the size ofthe charge ofY powder in relation to the size of the' bonib.y

A paper end eisem loyedso that between the `same .and the dis `l1ead .5v the rcharge .of r'ing-powder .is confined'. The cylindrical body formed by the `disk-:heads c' b and cy lindrical shell c contains a powder-ignitingandburstin .charge f in the central portion and circulary arranged' superimposedser'ies of disks Aof pyrotechnic material closely .ar-

ranged within the cylindrical shell ,c and leaving a space inthe center for anuample yigniting and burstin` char e of powder In the'di'sk-fhea wan thrcmgli.thecenter of .the .same l place .av .paper tube 7i surrounding the same Aan annulus 7c' .of pyroL technic material. This rests nponztlie-.oufter surface Aof thewdisk-ehead c, `closely surrounds the paper tube it', and extends outwardiitogaiiextent substantiallyagreeing with l,thatlofthe end of the paper tube. lin the inner .end ofthe paper tube h I placefthe .time-.fuse ai, 'the projecting `ends thereof ,beinggi'nthechargecof powder f, while inthe outer-end ofsaidpaper tube h Iprefer to-y lace a .short -stickofrnaterial 7c similar to. e pyrotechnic materiali 1c..

,Z represents `a quickmatch for fuse,- which may be of vany desired.length,the parts being preferably Vheld together 'with .a paper .strap as wound backend forth, one end ofv `this quick-matchentering tlievpaper or cloth rcaroo terial m, surroundin and extending over the pyrotechnic materia s kk and the end of the paper tube 7L. This inclosing material m not only connects the quick fuse or match Z to this end of the bomb, but supports the same in its relation thereto, with the free end of the said match within said parts and terminating adjacent to the surfaces of these parts.

Z represents aquick match or fuse, with one end projecting in the paper or cloth inclosing material m, coming adjacent to the free end of the quick match or fuse Z, and this extends out and down the outer surface of the material lc, over the surface of the disk-head a, down the outside of the cylindrical shell c, and passes into the paper cover e withl its other free endin the charge of firingpowder CZ.

In the operation ofthis pyrotechnic device the same is placed in amortar for firing in the position Fig. 1, and the end of the quick match or fuse Z is ignited. This burns through within the paper or cloth closure m, simultaneously igniting the end of the quickmatch Z and setting fire to the pyrotechnic materials k lc. The quick-fuse now burns outside the bomb andaround and communicates with the firing charge of powder d, explodin the same and causing the bomb to be ejecte from the mortar and thrown upward into mid-air. During the upward movement of the bomb the pyrotechnic materials c 7c are burning with a scintillating effect, leaving a tail of fire and roducing a visible rocket effect-that is, in caving a tail of fire behind as the bomb ascends.

The parts are so proportioned and arranged that the pyrotechnic materials Zc lc are used up during the ascent of the bomb. As soon as the portion k is consumed the fire communicates with the time-fuse i, the action of which is not quite instantaneous, but

. would possibly prevent the further ascent of the bomb. The fire from the fuse i ignites the powder f and simultaneously ignites all of the series of disks g of pyrotechnic material, the ignition of the powder charge f bursting the bomb and blowing the paper parts to atoms and at the same time scattering the lighted disks g, which produce the effect of star's, they quickly burning and leaving nothing but possibly light floating ash in the air.

The essential part of this invention is the pyrotechnic materials Zc 7c for producing the rocket effect, and this ma be employed in connection with a bomb o any character or construction. Therefore I do not limit myself to the precise construction of the bomb,

LC'as the same 'may be of the construction shown or of other well-known constructions, it being a fact that in the construction of some bombs and in addition to the parts herein shown and described there have been emplo ed arachute Aand asteroid effects-that 1s, lighted burning and during the ascentI of the bomb to give offv a tail of fire simulating an ascending rocket.

2. In a pyrotechnic device of the character described, a structure of pyrotechnic material adapted when burning to give off a tail of fire simulating an ascending rocket, a quick fuse or match for lighting the same and simultaneously lighting a second quick fuse or `match extending to the charge of firingpowder for propelling the bomb.

3. In aA pyrotechnic bomb device of the character described, an external structure of pyrotechnic material independent of butv connected to the bomb at one end and adapted when burning and durin the ascent of the bomb to give off a tail of re simulating an ascending rocket, a quick fuse or match device for igniting the said material and simultaneously igniting a second quick fuse or match device for igniting the firing or propelling charge of powder for discharging the bomb from the mortar.

4. In a pyrotechnic bomb device of the character described, a tube passing through one head of the bomb, an annulus of pyrotechnic material surrounding the same, a covering material therefor connecting the same to the bomb, a piece of similar pyrotechnic material within the outer end of the tube and a time-fuse within the inner end of said tube,

y and means for igniting the said yrotechnic materials so as to give off a tail o fire during the ascent of the bomb simulating an ascending rocket.

5. In a pyrotechnic bomb device of the character described, a 'tube passing through one head of the bomb, an annulus of pyrotechnic material surrounding the same, a covering material therefor connecting the same to the bomb, a piece of similar pyrotechnic material within the outer end of the tube, a time-fuse within the inner end of said tube, a quick fuse or match, and means for supporting the same with a free end thereof adjacent to said annulus of pyrotechnic material, and a second quick fuse or match extending therefrom to the firing charge of powder for propelling the bomb from the mortar, the first said quick-fuse simultaneously igniting the pyrotechnic materials and the second quick match or fuse.
