ADOLPH L; DUE, OF READING, OHIO. v

SKY-ROOKIE '1.

Be it known that I, ADoLPH L. DUE, acitizen of the United States, residing at Reading, in the county of Hamilton and State of Ohio, have invented a new and useful Im rovement in Sky-Rockets, of which the fol owing is a specification.

My invention relates to the class of rockets used for pyrotechnic displays, and more particularly to the method of attaching the sticks to such rockets.

It is well known, and has long been known, that the use of such rockets, and especially the use of the larger sizes, involved danger reason of the fact that the sticks, being .attached to the body of the rocket, which,

not being disrupted by the explosion, adheres to the stick and makes one end heavier than the other so that the stick descends with its longitudinal axis practically vertical. The lon fall imparts such momentum that the stic ,coming down head on, is a dangerous factor.

The object of my invention is to provide a rocket, adapted to serve the ordinary function of a sky-rocket, but free from the dan- 4 gers resulting from the end-on descent of the stick, and my invention consists in the com bination and-arrangement of partshereinafter described an d claimed.

In the drawings, Figure 1 is a side elevation of a rocket embodying my invention and showing the stick detachably connected; Fig. 2 a side view of the rocket proper and its. head without the stick; Fig. 3 a side view of the stick as used for detachable connection and Fig. 4 a side elevation of the rocket with stick permanently attached.

the rocket which contains the propelling composition, B the light casing or head which contains the exploding charge and colors. These parts are of ordinary construction. C represents-the stick which, instead oi being secured to the rocket casing, as heretofore.

is secured to the head. In the form shown in Figs. 1 and 2, a socket D, adapted to receive and frictionally hold-the end of the stick, is secured to the head by means of wires E. In the form shown in Fig. 4, the stick is directly secured to the head by means oi wires E.

Heretofore the sticks have been secured to the heavy casing, or body oi the rocket, which is not destroyed-by the explosion and remains attached to the sticks, which, thus weighted, come down with such force as to embed themselves in the ground to the depth of two or three inches or to pierce an inch board. If one of them should happen to strike a person serious injury or even death might result. When the sticks are attached to the head of the rocket, which is disrupted by the explosion, the st-iclts, being l'ree, come down slowly with their longitudinal axes practically horizontal, though the movement is undulatory. This obviates the danger which has heretofore attended. the fall of the rocket sticks. i

I claim as my invention.
