C. N. MARI Dec. 26, 1950 ROCKET Filed March 4, 1947 gwuc/wbob, CharZes AKA/100w;
Patented Dec. 26, 1950 UNITE DI STATES ATENT OFFICE.
'Z'Olaims. 1.;
M present invention. has for its. objects;
1; To. provide .a. novelty in..pyr.otechnic displays forpublicenjoyment- 2. To. provideameans .of. defenseagainst airboime invasions, etc...
In its generic nature m invention consistsof a dustcarrying rocket which opens at the desired height discharging dustot flammable pulverized materials to. form a. dust. cloud. which. can be ignited by the rocketitself. orby. other exploding rockets. carrying. incendiaries. or compressed. in.- flammablegases.
Ihit's more. detailed nature, the. invention, residesinthosenovel details of construction, comb'ihation. and; arrangement. of. parts. which will hereinafter first b.e,described.in.detail and-then be specifically. pointed. out in theappen dedelaims, reference being. hadto the-accompanying drawingin which:
Fig.1 is a side. elevation. of preferred embodi, mentofimy invention.-
Fig. 21 is a bottom. plan. view. of. thesame.
Fig. 3. is. a longitudinal. section..
Fig, 4 is atop planview of the inventiomthe cap being omitted.
Fig. 5' is. a cross. sectionon the, line 5-5 of Fig; 3.
Fig. 6 is a cross section. on. the. line, 6-6. of Fig, 3.
Fig. 'Z' is adetaillongitndinal section ofablank cartridge hereinafter specificall referredtd.
In the drawing in which like numerals of reference indicate likepartsinall the figures, I represents the barrel of the rocket, the upper end of which has a construction 5' serving as a stop for the;-fuel. cartridges |.5;and' stopper or plug 6 while the lower end of which. is provided with a quick-screw. flanged ring. 4.tha.t. prevents the fuel cartridges falling out and'permits passage of the cartridge fuse l6.
At. a suitablelocation along the barrel l is secured aaflanged disc 2 beneathwhich vanes 3 are; mounted forthe-usual' purpose. Above the disc 2 and restingthereon is a" dust container composed ofcylindrical segments Thavingbottom segments 8 and top segments 9-so designed that when closed together around. the barrel (Figs. 1 and 3) they will form a cylindrical container for dust 20; The container fits the flanged. disc 2 whose flange retains the bottom segments tog ether in closed'position.
A conical fiangedcap It" placed over the upper end of the container holds that end closed together. Each segment I has radially inwardly projecting side flanges H! which fit close together when the container is loaded and in place.
-' e Application-MarchA, 1947, SerialNo. 732,165
An. explosion cartridge. II' is.- provided with a clip I3 by means. of. which it. is secured. to. the barrel I. within the container (Fi s 3 and'5;)I, a fuse l2. leads. from, the cartridge. to the upper end of the barrel I.
A: suitable number. of iuel cartridges, 1 .5" filled with fuel I9. of any suitable. kind and fuse-connected together are placedin the barrel, thefirst cartridge. 1.5 having two chambers, one for. the fuel. and one. for an explosive. ILseparated' by a partition 2|. Thenumber oi iuelcartridges used will dependv on, the. height. to. whichthe rocket shall attain.
A. fuse is: connects. the iuelchamber. of' the cartridge 5. with the explosion chamber (Fig. 3).
When the barrelis no.t1t'o. be filled with. fiielcharged cartridges, l5 cylinders or dummy cartridges i5 (Fig. 7) may. be, used as fillers below the string of fuel. cartridges, inwhich event the starting fuse. 16 will be long. enough to pass through the cylinders. 15'? and. through the ring 4 as will. be obvious.
Operation On igniting fuse; I5; the fuel, cartridges, (Well known). will: be successively consumed, propelling the rocket upwardly. When the desired height is-reachedfuse is will be ignited and in turn set on the explosive H whichwillblow out stopper 6.-and.blow ofi: cap I4, whereupon the'segments 7', 8; 9 will fly openasindicatedlin: the direction-.01 the arrows in Fig. 4,- releasing'the dust 2|} and ignitingfuse [2.
The dust container, released at the; top of the barrel by the forceof the windand weight of the dust,, opens upIumbreHa. like scattering the dust tothe-wi'nd. Erplcsive cartridge M will then-act toignite the released. dust. producing. a silentexplosion or. flame;
By firing a sufficient number of these rockets a large cloud. can, be formed through which the unsuspecting enemy. would go-and envelopeitself. Almost any kind of pulverized materials can: be used. such asfiountalcum powder, resins, coals, pyrotechnics, explosives, etc. A mixture of fine materials. is. preferred; the fine. dust.wou1den:- velope, every part. of the. planeand inexploding interfere with the motor carburaficn. slowing downits. regular. function... Aerial navigation is also interfered with by the. giant. air. pockets created. by the. giant flames,. also bydisturbing and demoralizing. the crews whichcanbe afiected by the. gases, produced by. the explosions.
This is particularly efiective in the case of air borne invasions; the sky can be converted into a gigantic wall of fire through which a parachutist would have difficulty to escape and the 3 fire can be fed and maintained by rockets indefinitely.
Various modifications of the rocket will readily occur to those skilled in the art, without departing from the invention as defined by the appended claims.
What I claim is:
