Application fi1ed June 3, 1918. Serial No. 237,874.
To all whom it may concern:
Be it known that we, Anonin D1 GRAZIA, a subject of the King of Italy, and RAY BIAGINI, a citizen of the United States, residing at Charleroi, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Self-Propelling Aerial Bombs, of which the following is a specification.
Our invention relates to improvements in aerial bombs and has for its object to provide a device of this class embodying a selfpropelling dirigible vessel containing a prime mover of suitable type adapted to be operated for a definite period and to be then discontinued, whereupon the propulsion of the device will terminate and it will fall by gravity until coming into interference with any obstruction, resulting in an explosion and destruction of the mechanism with accompanying distribution of projectiles and fuel in combustion, as more fully hereinafter described.
Referring to the drawings illustrating certain preferred embodiments of the invention Figure 1 is a view in elevation showing the device in position formaking a flight;
Fig. 2 is an end elevation from the rear;
Fig. 3 is an enlarged longitudinal horizontal section, partly broken away, indicated by line III, III of Fig. 1;
Fig. 1 is a view showing a modified construction of the primer pins; and
Fig. 5 is a cross section on the line V, V of Fig. 3.
Fig. 6 is a diagram showing a conventional ignition system for the engine.
' The body of the device is generally cigar shaped, or of other suitable form, adapting it for travel through the air with a minimum of resistance, and is inclosed within a surrounding shell 2 of sheet metal or other suitable material, the rear portion 2 contalning' the mam explosive charge being preferably of a thin shell of aluminum. Within said aluminum shell and arranged centrally of the body portion is the main explosive-containing shell 3, preferably of steel, containing a charge of high explosive 4 of any suitable material as powder or T. N. T. Surrounding said explosive and contained within an outer surrounding shell 5 is a charge of bullets, shrapnel or the like 6, adapted to be scattered in various directions upon explosion of the main charge 4.
Between the shrapnel charge and the outer shell or casing 2 is a surrounding annular cavity which is filled with gasolene or other highly combustible fluid mixed with a suitable proportion of waste or other similar material as indicated at 7, adapted to hold portions of the combustible fluid when scattered in various directions, whereby to maintain continuous combustion thereof.
The main vessel is provided with suitable wings or planes 88 extending laterally at each side and of proper size and proportions to maintain the vessel in continuous flight under impelling action of a propeller 9. Said propeller is mounted upon the forward end of the driving shaft 10 which is actuated by a fluid combustion engine 11 of any suitable type, but preferably a gas engine utilizing gasolene as fuel. Gasolene for such purpose is contained in tank 12 at or about the middle body portion of the vessel, shell or casing 2 and terminal end walls 131l respectively. Between front wall 13 and the supplemental comparatively thin wall 15 is a supplemental charge of explosive 16 in communication with the main explosive charge 4 by a fuse 17 within a communicating tube or conduit 18. Forwardly of partition 15' and within a suitable casing 19 is an initial explosive charge 20, the purpose of which is to destroy the ignition connections from a battery or magneto to the spark plugs of engine 11 for the purpose of rendering such engine ineffectual upon explosion of the charge 20, so as to terminate operation of propeller 9. The electrical circuit connections for the ignition are merely indicated by wires or other suitable connections 21 leading to a commutator 22 of usual construction and adapted to be rendered useless upon explosion of charge 20. Any suitable wiring for the circuit may be adopted, as indicated in Fig. 6.
It is designed that charge 20 may be ignited at any predetermined time after the commencement of the flight of the machine, for which purpose we use a time fuse 23 inserted into communicating contact with charge 20 so that, depending upon the length of the fuse and the time of its combustion, the explosion will take place at a certain number of seconds or minutes after the machine is started. The engine is surrounded by a casing 2 as indicated, and is provided with one or more hinged hoods or doors 24 for access to the interior, as will be readily understood. Gasolene is furnished to the engine through a suitable carburetor 25 from tank 12, as indicated, and the several parts of the engine are similar to the usual gasolene motor commonly employed in aeroplane and automobile work.
The machine is provided with upper and lower stabilizing fins 2627 properly braced as indicated, and planes 8 are also preferably arranged in the manner indicated in Fig. 1, inclining upwardly toward the front, whereby to facilitate rising or soaring action. 7
' The rear end of the machine is closed by a terminal cap 28, preferably of steel, suitably connected to the main body portion, within which is provided a steel plug 29 having a central port 30 in direct communication with main charge 4. Plug 29 is provided with a central primer 31, and a plurality of firing pins 32 are mounted in divergent arrangement as indicated, each pin being adapted to be brought directly into firing contact engagement with the primer 31 upon coming into contact with any obstructing object so as to fire the explosive charge 4. Pins 32 are slidably mounted in the outer portion of cap 28 and are preferably maintained in retracted or extended position by spiral spring 33, easily compressible upon exertion of a forcible thrust inwardly of either pin. Each pin is also preferably provided with a series of slopingly arranged spurs or barbs 34, projecting angularly as indicated, so as to insure engagement against any obstructing object, as for instance, wires, foliage, or the like.
For the purpose of starting the apparatus in flight at any desired angle, we preferably employ an adjustable skidway or platform 35 having side bars 36, upon which supporting wheels 37 of the machine are adapted to run. Said wheels are located in suitable positions at the terminals of conveniently arranged frames 38, wheels 37 being located sufliciently apart to stabilize the machine in starting. Skidway 35 may be adjustable with relation to a horizontal base 39 by any suitable means, as gearing 40 and a screw 41, the skidway being pivotally mounted at one end as indicated at 42.
The construction and operation of the invention will be readily understood and appreciated from the foregoing description. Engine 11 being actuated by propeller 9 will carry the machine along upon wheels 37 until it is in flight, and the machine will travel in the desired direction and for the desired distance during the predetermined period of time, whereupon, fuse 23 will ignite charge 20, will estroy the engine ignition, and thus result in stoppage of the propeller. Thereupon the machine will assume an approximately vertical position by gravitation. tipplng backwardly and falling vertically,
because of the greater weight contained in its rear end, and will fall until one or more of the igniting pins 32 strikes an interfering object resulting in ignition of the primer of the main charge, with the resulting explosion of supplemental charge 16, resulting in complete destruction of the device itself, violent distribution of the shrapnel, and the gasolene-invested waste or the like, with the accompanying destruction or conflagration of any object which is the intended destination of the bomb.
