To all whom it may concern: Be it known that I, FRANK Snon'r, a cltizen of the United States, and a resident of Penn Yan, county of Yates, and State of New York, have invented an Improvement in Bombs, of which the following is a speclfication.

The invention described herein' may be used by the Government, or any of its 05- cers or employees in prosecution of work for the Government, or by any other person in the United States, without payment to me of any royalty thereon, in accordance with the act of March 3, 1883.

The subject of this invention is a'bomb, the invention relates more specifically to the stabilizing fins of a bomb.

In the construction of'bombs it is necessary that the tail fins be properly braced in order that they may withstand theqpressure placed upon them during flight as well as to avoid distortion of and shipment.

The present invention provides a fin struc ture which gives a self braced fin thereby avoiding the necessityfor stays or braces between the fins. w 1

It is also an object of the invention to 1'0- vide a fin or fins between which a con ed air space is provided so as to stabilize the bombs With the foregoing and other objects in View, the invention resides in the novel ar rangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit ofthe invention.

A practical embodiment of the invention is illustrated in the accompanying drawing, wherein:

Fig. 1 is a view in elevation of a bomb constructed in accordance with my inventionv Fig. 2 is a rear end elevation of the same; F Fig. 3 is a section on the line 3-3 of I 1g. 1' v Fig. 4 is a section on the line 44, of

Fig. 9 is a rear end elevation of the same;

Fig. 10 is a section on the line 1010 of Fig. 8;

ig. 11 is a sectional view showing a still further modification of the fin shown in Fig. 8;

Fig. 12 is an elevation of a bomb showing astill further modification of the fin;

Fig. 13 is a rear end elevation of the same;

Fig. 14 is a section taken on the line 1i14 of Fig. 12; and

Fig. 15 is a detail sectional view of fins formed to provide air passages therethrongh.

Referring to the drawings by numerals of reference:

The usual bomb nose is shown at 20 to which is attached in any suitable manner the bomb body 21 which is formed from tubular material swaged on a. suitable mandril to draw the rear end of the tube A to proper stream line as shown and atthe same time fold spaced apart portions of the tube outwardly to form fins 22 substantially of V-shape incross section, the fins in this instance being preferably stream lined or tapered toward their rear end.

In Fig. 5 is shown a tubular body 21 connected to the bomb nose and to the rear end of the body is connected a tail piece 23 which is formed preferably of tubular material placed upon a suitable mandril and swaged to draw the tube to a coneand to fold spaced apart portions of the tube out wardly to form the fins 22' which are subwhich at the point of'joining with the cone gradually taper toward the front and rear stantiallyof V shape in cross section and In Fig. 11 the same form of tail piece and fin is shown with the exception that the vane 24' is made of a separate piece clamped between the fin members to which it is riveted or otherwise joined. While the vane as herein shown is a separate piece of sheet metal it is to be understood that the same may be integral with the fin proper, in which instance the vane would be divided along its inner edge to form the fin, or it may be of sheet metal folded upon itself to form a fin of V or Y shape in cross section, and secured to the tail piece'or bomb body along its two edges.

The modified tail piece and fin shown in Fig. 12 is constructed in the same manner as the fins heretofore described, the difference being that the fins 26 are wider at the rear end than at the forward end thus pro- ,ducing a certain amount of vacuum at the rear end of each fin and so controlling to some extent the flight of the bomb.

In Fig. 15 a fin similar to that shown in Fig. l is illustrated the fin being open at the forward end so as to provide an air passage therethrough thus aiding in stabilizing the bomb during flight.

While I have illustrated and described herein fins made integral with the tail piece, it is to be understood that the fins may be formed separately and attached by riveting or welding to the tail piece or bomb body.

. I claim:

1. A bomb, embodying a tail piece, finsintegral with the tail piece of substantial V-shape in cross section, each fin open to provide an air passage therethrough.

2.- A method of forming self braced bomb fins, consisting of drawing a tube into a cone and at the same time folding portions ofthe tube at spaced apart intervals thereabout outwardly.

3. A bomb, embodying a tail piece, fins carried by the tail piece of substantially V- shape in cross section, the walls of the fins spaced farther apart at points in advance of the trailing edges.
