H. REIHLEN DETONATI NG FIREWORK Filed Sept. 2l, 1927 INVENTOR with the -guinj arabic-gun powder solution, whereupon the tubular casing Slis flattened downl upon the wick enclosed therein, as shown in Figure of the drawings; While'it is preferred to'einploy the paper casing in? initialt'ubular' form as above stated," this is not absolutely essential, since a flat paper sheet may be used and `folded longitudinally upon itself around the wick, to produce theV flattened tubular Wrapper characteristic 'of the grasshopper firework device.;
After the` prepared wickis thus inserted in VVthe flattenedftubular casing 3, thelatter is 5 transversely foldedback and forth Tupon it,
self inf zigzagfashion to provideia seriesfof connected sections of desired number and desired individuallength (see Figuresjnl the wrapper o rgcasing (which may-,be done either byhand or by 1nach1ne) exerts a squeezingor compactlng pressure upon' the portions of gthe dry powder encrusted wick..
which are disposed at and adjacent to the line of fold, whereby the .dry adhering powder at the rwick-portions experiencing such pressure 'tion Sinterrnediatethe folds 3f the dry afdheri-ngpowderon the portions ofwick eX-y tending therethrough/ijs left'relatively free and uncompressed so as tov be capable of comparatively rapidcombustion within the con f lined interior spacesof the sections 3',
consequently, when ignited, the'rapidexpansionvof- 'the gases ofcombustion within-the conlined space of the'section interiors `will burst the walls thereof with a loudreport@ orV detonation. Thes'wick-sections or links 44` Awill burnwithfa relatively slow but neverthe less'A sure'comb-ustion, and' will[serve to carry anigniting *spark around the-folds i vfrom an exploded section tothe-next adjacent section, wherein combustion again becomes :rapid with desired detonating effect,"L Thus Y'the complete` devicewhen ignited at one Vend "will progresisvely Vburnlfrorn section to seci tion towardfthe other end, and in. the course o f combustion will 4produce a series offsucces--v` sive explosions, fupon the occurrenceof each of v'Which the device as a whole Vwill juanp. about, Jfrom vwhich action the naine grass- After-thelcasing is folded to producethe Yb ody comprisingthe series Vof connected' s ections 137', said bodyiswrapped transversely 'with' a retaining tie 5 ofi-cordel' the like,Y to
retainV the sections against separation from folded' relation both duringhandlingof the 5 sans@` and duringY thejdetonation thereof. Y
In order to provide a convenient point for *initial ignition of the device, one end of the wick l is allowed toiproject exteriorly from 'aneud sectionV 3'* ofthe device, and this free endof the wick isdipped in a strong solution ofA guinarabic andgun-powderto form there- -fuse 6. ,It will be obvious, however, that an `Vtion fof' the deviceto serve as an igniting fuse, if such arrangement is preferred.
