ROCKET.

Specification of Letters Patent.

Patented Mar. 18, 1919.

Application filed July 15, 1918. Serial No. 244,828.

T 0 all whom it may concern:

Be it known that I, HENRY J PAIN, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented an Improvement in Rockets, of which the following is a specification. I

' This invention relates to a rocket, and more particularly to a signal rocket, although as will be understood, its particular use is not so limited, because obviously it may also be used for display and other purposes. Heretofore, in the manufacture of signal rockets, in order to maintain the signal light inan elevated position as long as possible, it has been customary to employ in conjunction therewith, a parachute or other similar means for maintaining the signal light when ignited in the air. Rockets of this type are used extensively for signal purposes by the armies and navies of the nations engaged in the war, and due to the poor quality of material obtainable for the parachutes and-possibly to imperfection in manufacture, it has been found in prac tice that an exceedingly large percentage of parachutes fail' to perform their intended functions.

. In order to obviate this difiiculty, and at the same time to increase the intensity of the signal light, I have proposed to dispense with the arachutes in the manufacture of signal roc ets, and to so construct the rocket that the signal light or star member thereof is simultaneously lighted or ignited in firing the rocket at a plurality of its parts. By so doing, I have found that the signal light or of the rocket remains in the air suiiiciently long for the intended purposes, and at the same time gives a largely increased light and hence a correspondingly increased range of visibility.

The rocket constructed in accordance with my present invention will be hereinafter more articularly described in conjunction with tihe accompanying drawing, in which Figure 1 is a central longitudinal cross-section of a. rocket illustrating the invention,

and Fig. 2 is a cross-section on line *2-2 of Fig. 1.

' Referring to the drawing, it will be seen that in carrying out the invention I employ the usual cylindrical case 10, forming the body ofthe rocket, and as is customary this maybe made of cardboard, paper or any other suitable material. Secured to the case the signal light atboth ends thereof.

10 in a convenientposition is a SOCIMZL 11 for receiving the stick, upon which the rocket is placed in being fired. One end of the case 10 is constricted as indicated at 12 and open as designated by 13. At asuitable distance from the open end of the case a transverse head or partition wall 14 is suitably fixed therein. Between the head 14 and the open end of the case the rocket is provided with an elevating charge of the material usually employed as indicated at 15. This is made with a bore16, so that when ignited by a match, fuse, or otherwise, the gas generated by the burning charge is emitted so rapidly at the open end of the rocket as to so act against the air as to cause the rocket to rise.

In the opposite or closed end of the rocket, I employ a signal light, or so called star, indicated at 17. This is composed of'a suitable pyrotechnic material to give a required light when burning. It is customary to make these signal lights or star to show red, white, or green, but of course substantially any color may be effected. The signal light 17 is preferably covered with a suitable coating of a mixture ofalcohol and shellac and forced to place in the casing 10. Between the signal light or star 17 and the head 14 there is a signal firing charge indicated at 18. This is ignited by the inner end of the elevating charge 15 by means of a fuse or opening 19 in the head 14. V

In conjunction with the signal light or star 17 and in order to simultaneously light or ignite the same at the op osite ends thereof, I employ a plurality o fuses, indicated at 20. These fuses 20 are rapid burning fuses, and while I have illustrated three of them any desired number may be employed. Each fuse 20 extends along the outer surface of the signal light or star, extending an a preciable distance beyond the ends there- 0 and the extremities of the fuses are turned down against the ends of the signal light, so as to lie within

priming charges

21 and 22 of powder or other similar material, in or er to insure the ignitiolii 1of so as illustrated, this end of the case may be provided with a paper cap 23 or other suitable covering.

As-will now be apparent, the rocket hereinbefore described, upon being fired will rise in the air, and after the elevating charge 15 has burnedto the inner end, the signal light firing charge will be ignited therefrom and the signal light or star ejected from the case, and simultaneously, the firing charge for the'signal light, ignites the fuses 20 which ignite the priming charges and thus insure the substantially simultaneous lighting of the signal light or site ends thereof.

I claim as my invention:

1. A signal rocket comprising a case, a transverse partition wall therein, an elevating charge extending between the transverse wall and an openend of the case, a signal light in the other end of the case, and means associated-with the si nal light and fired by the elevating charge $01 ejecting the signal light from said case and directly and simultaneously igniting the same in a plurality V of its parts distant from'each other.

2. A signal rocket comprising a case, a transverse partition wall therein, an elevating charge extending between the partition wall and an open end of the case, a signal .light in the other end of the case, and means associated with the signal light for ejecting the same from said case and directly and simultaneously lighting the opposite ends thereof. j

3. -A signal rocket comprising a case, a transverse partition wall in the case, an elevating charge extending between the transverse wall and an open end of the case, a signal light in the other end of the case, a

star at the oppo- I charge between the signal light and the al light and running longitudinallyv of the'ends of-the signal light are ignited substantially simultaneously upon the signal being ejected from the case.

4:. A signal rocket comprising a case, a signal light contained in the said case, a charge for ejecting the signallight from the said case, and a fuse extending beyond the endsoftlre signal light and having its ends turned 'over the extremities of the signal light so that when ignited from the charge for ejecting the signal light from the rocket case, both ends of the light are ignited substantially simultaneously.

5. A signal rocket comprising a case, an elevating charge therein, a signal light also in the said case, an ejecting charge ignited from the elevating charge for expelling the signal light from the rocket case, and a fuse extending beyond the ends of the signal light. and folded over the same so that ,when lighted from the ejecting charge, both ends of the signal li ht are ignited thereby substantially simultaneously when the signal light is ejected. from the rocket case.

Signed by me this 15th day of June 1918.
