Application September 30, 1935, Serial No. 42,917 (01; 102-23) I 7 Claims.

This invention relates to special packages. It has for its object the provision of a package for pyrotechnic devices such as sky rockets, roman candles, etc., which shall function alternatively as a shipping container for the pyrotechnic device as well as a support for the rockets, etc., when they are fired.

One of the objects of the inventionis the provision of a box or tube serving as a receptacle for the rockets, and having a slot or slots in one end so that the tube may be stood on the opposite ends and one or more rockets supported in firing position by having the shaft of the rocket thrust through one of the slots and the barrel of the rocket resting upon the upper edge of the tube or box with thefuse extending in position to be ignited, the tube or box acting as a support and guide.

Another object of the invention is to provide the container with a plurality of strips or legs normally lying substantially fiatagainst the outside of the container in the interest of conservation of space, with means carriedby the container for. expanding the legs so that they form a large and stable base or support for the container when it is employed as. a rocket guide or stand.

Still another object of the'invention is to provide a rocket package of the type described in whichthe legs are slidable as a unit longitudinally of the tube or box to bring the free ends of the legs within the bounds of the length of the container so that they will not project in shipping, and become broken, the legs being extensible'to the required distance and expansible, in the manner previously set forth. h

Other objects of the invention will appear as the following description of a preferred and practical embodiment thereof proce eds.

In'the drawing which accompanys and forms a part of the following specification and throughout the several figures of which the same characters of reference have been employed to designate identical parts:

Figure 1 is a view in elevation of the rocket H package in shipping condition;

Figure 2 is a longitudinal section through the same;

Figure 3 is a longitudinalsection through the same package illustrating the legsexpandediin supporting condition and rockets placed in position to be fired;

Figure 4isa plan view of the device as shown in Figure 3; and I Figure 5 is a view in elevation of a modified form of container, the upper part being broken away.

Referring now in detailto the several figures,- the numeral l'represents a tubular container or receptacle, theshape however being immaterialto the invention, excepting of course that it is an elongated receptacle adapted to contain pyrotechnic pieces such as sky rockets or roman candles. The tube l maybe made of. any suitable material such for example as pasteboard; There is'a closure 2 at oneend of the receptacle which in the preferred example is of cup-like form defining a surrounding flange 3 extendingoutwardly from the end of the receptacle. The lower end of the tube is closed byv a cap 4; Figure 2 shows that the receptacle thus constituted is adapted to contain a plurality of rockets. Since it'is to function not only as a shipping receptacle, but as a: support or stand to guide the take-off of the rockets, it is necessarily provided with special features. which differentiate it from an ordinary tubular container. g I

For example, the rockets areintended to be removed from the receptacle by taking off the cap 4, and thecclosure 2 at the upper end is provided with one or more slots 5 as shown in Figure 4 through which the shafts ,6 of the rockets may be thrust as illustrated in Figure-3. the barrels! of the rockets being adapted to rest upon the flange 3, the latter preferably engaging the barrels between .the shafts 6 and the fuses 8.so that the latter extend peripherally outwardly as shown in the most convenient position to be ignited. Since the closure 2 is-perforated by the slots 5, it may be desirable in shipping 35 to provide an outer cap 9, see Figures 1 and 2, in order to seal the contents of the package against the entrance of dampness, dust, or other objectionable substance. p v

In order to enhance the stability of the tube I when it is stood uponend to function as a rocket support and guide, it is provided externally with a plurality of legs l0. These do not have to be very "sturdy; strips of pasteboard answer the purpose very well. In that form of the invention shown in Figure 2, the legs ID are glued orotherwise fixed to the wall of the tube, I in a zoneintermediate the ends of thesaid tube and are free from said tube throughout the rest of their. extent. Normally, they lie substantiallyf flat against the tubeand project beyond it ,at one end as indicated at l l in Figure 1. The tube is provided with a relatively thick ring I2 of pasteboard or the like, arranged beneath the-three portions of the legs l0 andfslidable along the tube I beneath said legsand being retained against accidental displacement by the presence of the cap 4. When the ring is slipped upward beneath the legs I0, it pries the legs apart so that when it reaches the uppermost position as illustrated in Figure 3, the legs have assumed a divergent relation which defines a broad base of support for the tube I. Since it i's'desirable in order to secure the maximum height of flight for the rockets to minimize or completely eliminate any reactive yield of the support, thehlegs are preferably of such lengththat when fully distended the end of the tube I rests firmly against the ground or whatever.

surface the support may be resting upon.

In shipping and until it is desired to fire the rockets, it is preferred to hold the legs ID as close as possible to the body of the receptacle. This is accomplished'by means of a rubber band I3 which surrounds the legs under tension. The tension of said bandalso presses the legs into frictional engagement with-thering I2 constituting an additional safeguard to prevent displacement of the same.

It may be objected to the above construction that the extensions I I of the legs cause the package to occupy more space than is necessary in shipping, and furthermore, that they may readily become creased or broken preventing the receptacle from standing level. In Figure 5, the whole leg unit is slidable along the tube I and in the normal shipping position the ends of the legs restagainst the ring I2 where they are completely within the length dimension of the receptacle and shielded from being broken. The upper ends of the legs are free with respectto the tube I, but suitably secured to a sliding ring or carriage I4 which may be of paper or any other inexpensive material. Sturdiness is not an essential factor for .this part of the construction. In this form of the invention as in the form first described, a rubber band I3 surrounds the legs when the receptacle is in ship.- ment or on sale holding them close to the tube, conserving the space which the receptacle occupies'in shipment. When it is desired to set the receptacle up as a take-off'stand for the fire works, the rubber band is removed, the paper ring I4 slid downwardly with the legs unit'arily associated therewith andthe thick ring I2 slid upwardly to expand said legs. The receptacle then has the position identical with that shown in legs so that the trajectory of the rockets will be a through flight and not'an erratic course which'may land them in'the midst of the. on-

lookers. a

While I have in the above'description disclosed What I believe to be a preferred and practical embodiment of my invention, it will be understood to those skilled in the art that the details of construction as shown and described are by way of example and not to be constructed as limiting the scope of the invention as claimed.
