7 Claims.
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

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.
