IMPROVBD SKY-ROCKET.

TO ALL WHOM IT MAY CON CERN Be it known that I, JOHN W. Haumann, of East Williamsburg, Queens county, New York, have invented a new and useful Improvement in Sky-Rockets; and I do hereby decla-re that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a. part of this specification. l I

This invention consists in dispensing with the long stick or guide which is now attached to sky-rockets in order to insure a straight upward flight of the same in the air, and using instead three short guides, us hereinafter fully shown and described, whereby several important advantages are obtained,'to wit, the packing ofthe rockets in a small space, so as to economize in transportation; lthe forming of a stand or support for the rocket, so that no fixture of'any kind will be required when .it is to be tired or set off," and, lastly, the obtaining of an eiicient guide to insure the straight Hight ofv the rockets upward in the air. In the accompanying sheet of drawings- Figure 1 is an external view of my invention.

Figure 2, a diminished side view of the same, adjusted together .as when packed for shipment.

.Figure 3, an end view of the same.

Similar letters of reference indicate corresponding parts.

A represents the barrel of thc rocket, constructed in the usualn'ay, and B B B represent three short, light sticks, which are secured to the inner end of the barrel by means of wires a a. These stieks'are secured tothe barrel at equal distances apart, and they form a stand or support for the rocket, so that the latter` maybe fired or set oii without the aid of any particular guide or x'ture, as will be understood by referring to g.` 1.

The short sticks insure a straight flight of the rocket, and are far ulore eilicient in this way than the ordinar sinfrle lon stick, as the latter is neeessaril attached to the side ofthe barrel b awire, and,lconse uentl i l y a g y y q y is out oi' line with the axis of the barrel, and the latter is very liable to turn or be deilected in its flight to one side or the other by slight disturbing causes, such as the wind, or any irregularityin the burning of the charge.

By my improvement, it will be seen that the axis ot' the barrel is in line with the centre of the space between the three sticks B, and the rocket, therefore, is perfectly balanced, and will not be liable in its iiight to turn to one side more than to another, and, by this perfect equipoise, short sticks B, about one-sixth the lengthA of the ordinary rocket-stick, are only required, so that the rockets may be packed in a comparatively short case, two barrels being placed with their inner ends in contact, and the barrel of one rocket enclosed between the sticks ofthe other, as shown clearlyin fig. 2. Thecost of transportation,therefore, willbegreatly reduced, and this is an important feature, for it will be understood thatull railroad as well as other transportation companics require rockets and other fireworks tobe boxed, on the score of safety. They would not be received as freight, done up in paper. This boxing renders the shipping of rockets with the long sticks very expensive. Three sticks is the desirable number; to me there would be no object in applyingmore.

I claim as new, and desire to secure by Letters Patent- The attachment to a sky-rocket of 'three or' more sticks, at equal distances apart, substantially in the manner as and for the purpose set forth.

JOHN W. HADFIELD.
