MAGNETIC GUN.

Specification of Letters Patent.

Patented Dec. 9, 1919.

Application filed February 23, 1916. Serial No. 79,889.

To all whom it may concern:

Be it known that I, CHARLES E. MORRIS, a citizen of the United States, residing at Leavenworth, in the county of Leavenworth and State of Kansas, have invented a certain new and useful Improvement in Magnetic Guns, of which the following is a specification.

My invention relates to improvements in magnetic guns.

The object of my invention is to provide a gun from which a projectile may be hurled by magnetic force.

A further object of my invention is to provide a magnetic gun through and from which a magnetizable projectile may be projected by means of a series of magnetic fields which are consecutively energized and deenergized.

Still another object of my invention is to provide means by which such energizing and deenergizing may be controlled by the projectile itself.

Still another object of my invention is to provide a magnetic gun which is arranged to impart axial rotation to the projectlle.

A further object of my invention is to provide a magnetizable projectile so constructed that axial rotation will be imparted to it when fired from a magnetic gun of the proper construction.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing which illustrates the preferred embodiment of my invention,

Figure 1 is a vertical longitudinal central sectional view of a magnetic gun embodying my improvement. In this view, the pro ectile is shown mounted in the initial position.

Fig. 2 is a rear elevation of the gun.

Fig. 3 is a side elevation of the barrel.

Fig. 4 is an end view of the barrel.

Fig. 5 is a side elevation of the projectile.

Fig. 6 is an end view of the projectile.

Fig. 7 is a diagrammatic view of the circuit, in which are located the helices and the barrel of the gun.

Similar reference characters designate similar parts in the different views.

1 designates a base on which is rotatably supported on a Vertical axis a U-shaped standard 2, between the arms of which is plvoted on a horizontal axis by trunnions 3 a barrel supporting member 4 having two upwardly extending arms 5 at the front and rear ends thereof respectively in which is mounted a barrel 6 provided with a central longitudinal circular hole 7, which forms Elie 8passage for the magnetizable projec- The barrel 6 is preferably polygonal in cross section, the barrel shown in the drawmg bemg a tube which is square in cross section on its periphery and which is in the form of a square rod which has been twisted, as shown in Fig. 3, in the spiral form;

Encircling the barrel 6 and disposed one in front of the other and separated from each other by insulating collars 9 are a series of

helices

10, 11, 12 and 13. The windings of these helices tightly embrace and conform to the barrel. Those-portions of the windings nextto the corners of the barrel are farther from the aXis of the barrel, than those portions which lie against the fiat sides of the barrel. By reason of this construction, a spiral magnetic field is provided which serves to rotate the projectile on its axis.

The projectile 8 adapted to be used in this gun is provided with a series of spirally arranged peripheral ribs 14 disposed so as to correspond and coincide respectively with the spiral magnetic fields, created when the

helices

10, 11, 12 and 13 are energized. By

reason of this construction, the ribs 14 will be attracted by these spiral lines of force, and as the projectile passes through the barrel 6, it will have, axial rotation imparted to it.

In order that the

helices

10, 11, 12 and 13, which respectively form solenoid coils may be consecutively energized and deenergized, so as to consecutively magnetize and attract the projectile 8, so as to cause the latter to travel through and be projected from the barrel 6, the following described mechanism may be employed.

Secured in the barrel 6 and extending upwardly therefrom are a series of

tubes

15, 16, 17 and 18, in which are respectively mounted a series of vertically

slidable pins

19, 20, 21 and 22 which are normally forced by a plu rality of springs 23 located respectively one in each tube 15 to 18 to positions in which their lower ends will extend into the opening 7 so as to be consecutively struck by the projectile 8. The upper ends of the springs 23 are respectively held in place by caps 24: mounted in the upper ends of the tubes 15 to 18 respectively. p

The tubes 15 to 18 are so arranged relatively to the coils 10 to 13, that the projectile 8 in striking and leaving the pins 19 to 22 will cause the coils or helices to be consecutively energized as the projectile enters said coils, and to be deenergized, after the projectile has passed more than half through the diflerent coils.

To efi'ect this, the parts are connected in an electrical circuit which is arranged in the following manner.

Referring to Fig. 7, 25 designates an electrical generator, as for example, a battery, which at one pole is connected by a conductor 2'6 with the barrel 6, which is electrically conductive. Connected to the other pole of the battery 25 is a conductor 27 which is respectively connected to one set of ends of the helices 10 to 13 by conductors 2s, 29, 30 and 31.

The other set of ends of the helices 10 to 13 are respectively connected to the caps 24 and thereby through the springs 23 with the

pins

19, 20, 21 and 22 by

conductors

32, 33, 34 and 35.

When the projectile 8 is inserted in the barrel 6, the current will pass from the battery 25 by the conductors 27 and 28, thence through the coil 10, and thence by way of conductor 32, pin 19, projectile 8, barrel 6, and conductor 26 back to the battery 25.

The coil 10 will thus be energized and will draw into it the projectile 8. By the time the projectile has passed about three-quarters way through the coil 10, it will strike the pin 20 and the coil 11 will 'befenergized by reason of the current passing from the conductor 27 through the conductor 29, coil 11, conductor 33 and pin 20, from which the current will pass through the projectile 8 and back to the battery in the manner already described. In the meantime, the connection between the projectile 8 and the pin 19 will be broken, and the coil 10 will be thus denergized and will offer no resistance to the further forward progression of the projectile.

In like manner, the coil 11 will be dee'nergized when the projectile strikes the pin 21 and becomes disconnected with the pin 20.

In a similar manner, the

coils

12 and 13 will be energized and deenergized as the projectile strikes and leaves the pins 21 and 22, the current passing consecutively from the conductor 27 through the conductors 30' and 31 and the

coils

12 and 13 and

conductors

34 and 35 and pins 21 and 22.

The projectile will thus be forced through and discharged from the barrel 6.

In order that the electrical contact may be good between the projectile 8, pins 19 to 22 and the barrel 6, the grooves between the ribs 14 may be filled with some non-magnetic good conductor, such as brass or copper, 36.

The barrel support 5 may be provided with a handle 37 for swinging it on its vertical axis.

The barrel support 5 is provided with a projection 38 having holes 39 concentric with one of the trunnions 3. A bolt 40 mounted in one of the arms of the standard 2 is adapted to enter any one of the holes 39 for holding the barrel 6 in the position to which it may be swung with the support 5.

I do not limit my invention to the structure shown and described as modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.
