This invention relates to ?reworks and more particularly to skyrocket constructions. Among‘ the objects of the invention is to gener ally improve the construction of skyrockets and 5 like types of ?reworks which shall comprise few and simple parts which are easily assembled to form‘ an attractively appearing structure, which shall be cheap to manufacture, and which shall be 10" e?i‘cient‘and practical to a high degree in use. Other objects of this invention will in part be obvious and in part'hereinafter pointed out. The invention accordingly consists in the fea tures of construction, combination of elements and arrangement of parts which will be exempli 15* ?ed in the construction hereinafter described and of which the scope of application will be indicated in the following claims. In the accompanying drawing in which is _ shown one of the possible illustrative embodi 20 ments of this invention, Figure 1 is a front elevational view of a sky rocket construction embodying the invention. Figures 2 and 3 are enlarged cross sectional views taken on lines 2-2 and 3-3 in Figure 1. 25 Figure 4 is a cross sectional view corresponding to a cut taken on line 4-4 in Figure 2, and Figures 5, 6 and 7 are front elevational views of the separated parts of the skyrocket, namely, the cap, outer casing and shell, respectively, 30 shown‘ disassembled, said cap and casing being shown collapsed for shipment or storage. Referring in detail to the drawing, I0 denotes askyrocket type of ?rework constructed to em body the invention. Said skyrocket I0 is seen ggsfrom'Figure 3, to comprise a cylindrical type of shell I I which may be ?lled with a usual propel ling charge C in the lower end Ila thereof and also may contain an explosive and colored illumi nating display material (not shown) in the head 1s<r<end IIb. Said shell II and contents may be as sembled in anysuitable manner well known in the‘art; The charge. 0 is retained in the shell end IIa by a suitable plug closure I2 which is provided ;;> with an axial passage I2a through which a cord fuse I3 is inserted, a folded end I3a thereof ex tending into the charge C. A free‘end I3b of said fuse I3 projects beyond the shell end I la for setting off the skyrocket. ,n The novel construction embodying the, inven tion will now be described. Applied over the‘ ?lled shell II there is provided a casing I4 made of suitable sheet material, such as cardboard or the like. Said casing I4 preferably comprises a ,5 tapered tubular structure which may be collapsed (Cl. 102-—23) for shipping or storage before assembly, as shown in Figure 6, and as here shown when applied over the shell is of hexagonal cross section. See Fig ure 2, Said casing I4 has its lower end I4a sized to 55.. circumscribe the circular shape of the shell end Ila which snugly ?ts therein. The other or up per end “lb of the casing I4 may be made with ?aps Idc which are adapted to be bent inwardly toward the upper end III) of shell II, said flaps 101; I40 being so cut and shaped to slopingly embrace with the free edge Md of the ‘shell end I Ib, as shown in Figures 3 and 6. Said ?ap edges I M‘ may be‘secured to the shell end III) by a suitable adhesive I5. As a top cover on the upper or'lead- 15f: ing end of the skyrocket ID, a cap I6 is provided. Said cap I6 preferably is made of a sheet mate rial similar to that of the casing I4 and before assembly can be collapsed as shown in Figure 5. The cap I6 may be attached to the upper end 20>. of the casing I4 with the shell end IIb ?tted therein by suitable adhesive means I5a which also secures the flap edges Md to the shell end I I b, the outer surfaces of the flaps I 40 serving as a seat for the cap I 6 as shown in Figure 3. 25,1» Extending up along the casing I4 from the low er end Illa thereof, a slot I‘! is provided, said slot I‘! being of sufficient width to receive the usual stick I8 which may be of square cross section. As shown in Figure 3, the upper end of the stick 3055 I8 may be grooved as at I8a to engage with the inner edge portion of the slot IT. The side edges of said slot I1 abutting the stick I8 serves to re tain the stick I8 against side movement with re spect to the shell I I, as seen from Figure 3. 355'. To ?xedly secure the stick I8 in its assembled position, a binding wire I9, extending about the stick I8 and lower casing end Mb, is provided.' See Figures 1, 2 and 3. An additional novel feature of construction in 401' the assembly of the fuse I3 in the ?lled shell ‘is provided in having a member 20 extending from the lower casing end Mb. Said member 20 has an elongated opening 20a in the mid-portion thereof which is just large enough to permit the 45 passage of the folded cord fuse I3, said opening 20a being located to register with the axial pas sage I'Za when the member 20 is positioned to extend over said bottom of the shell and Ila, as shown in Figures 3 and 4. The free end 2% 50 of the member 20 may be inserted between the lower casing end I 4a and the shell end I Ib' to retain said member 20 in effective position shown in Figure 4. The fuse I3 when inserted into the opening 20a 55 2,128,586 2 and through the passage l2a has a short end 13a of the folded portion thereof within the opening 20a spring out of alignment with respect to the latter to act as a detent or stop against falling or being pulled out of the assembled position shown in Figure 3. In practicing the invention, skyrocket l0 may be shipped “knocked down” that is, the ?lled shell ll, casing M, cap l6 and stick i8 may be sep 10 arated for convenience and economy in packag ing, shipping and storage. To assemble the sky rocket Hi, the ?lled shells II are inserted in the casings M with the upper ends Ha of the shells coinciding with the curved edges 14d. of the ?aps 15 Me. By then dipping the upper shell ends Ilb into an adhesive supply for securing the edges Md of the ?aps Mc thereto, the outer surfaces of said ?aps Mo are simultaneously coated with the ad hesive I5a. The cap it is then applied in posi 20 tion. Said ?aps lilc are thus made to serve as a member extending from the other end of said Casing having an opening, said member and opening forming a fuse retaining means. 3. A housing for a ?reworks element compris ing a casing, ?aps extending from one end of said casing for securing the latter to the element, said casing having a stick receiving slot ex tending along a side thereof at a spaced dis tance from the ?aps. 4. In combination with a cylindrical shell ?lled 10 with combustible illuminating material, a tubular casing ?tted to extend over the entire shell, flap end portions extending from said casing, said ?ap end portions being constructed and arranged to conform to the shape and size of an end of the 15 shell, adhesive means for securing said ?ap end portions to the shell, and a cap seated on said ?ap end portions and secured to said casingto terminate said casing and shell. 5. A tapered shaped tubular casing adapted to e?icient seating means for retaining the caps 56. The sticks l8 may next be inserted into the slots 11 and the binder wire 19 clamped in place, as shown in Figures 1, 2 and 3. The cord fuse l3 may then be inserted into the 25 be collapsed when not in use and adapted to house a ?rework element, said casing being sub previously secured to extend across the bottom end of the shell Ma. and easing Ma. The fuse I3 is preferably made of a stiff, yet resilient ma cross sectional area being sized to snugly ?t said openings 29a. of the member 20, the latter being 301 terial and an end i3a thereof folded over on it self so that the folded portion Iila thereof is su?i ciently long to extend well into the charge 0. The short end B1) of the folded portion 13a, after entering the opening 26a will spring slightly out :of alignment with respect to said opening 20a and will abut said member 20, asv shown in Fig ures 2, 3 and 4. The skyrocket Hi will now be ready for use in the well understood manner. It will thus be seen that there is provided a device in which the several objects of this inven tion are achieved, and which is well adapted to meet the conditions of practical use. As various possible embodiments might be made‘ of the above invention, and as various changes ‘;might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense. Having thus described my invention I claim as new and desire to secure by Letters Patent: 1. In ?reworks construction of the character described, a shell ?lled with combustible illum inating material having an ignition fuse carried by one end, a casing ?tted to extend over the entire shell, means for securing a portion of the casing to the shell, and a hollow, tapered cap seated on an end of the casing and shell opposite 40.. said ignition fused end. 2.
