PROJECTILE FOR FIREARMS Filed Nov. 23. 1959 Fiji.
INVENTOR. ROBERT A. KLEINGUENTHER BY W ML fl TTORNE Y United a rfares 3,065,696 Patented Nov. 27, 1952 Free 3,065,696 PRQJECTILE FUR FIREARMS Robert A. Kleinguenther, 14627 Fairacres Drive, Whittier, Caiif. Filed Nov. 23, 1959, Ser. No. 854,822 4 Claims. (Cl. Mil-51) My invention relates generally to firearms and more particularly to ammunition therefor.
An objection of my invention is to provide ammunition in the nature of a projectile which is structurally characterized by means utilizing the gas pressure generated in the chamber of the firearm upon discharging the latter to not only propel the projectile but also to impart rotary motion or spin to the projectile, so as to dispense with rifling the barrel with its attendant disadvantages of causing excessive friction in the barrel and high pressure in the chamber as well as deformation of the projectile, all to the end of enabling the chamber pressure to be greatly reduced and a smaller charge of the most rapid burning powder to be used to enormously increase the velocity of the projectile and obtain vastly increased penetration of the target.
Another object of my invention is to provide a projectile of the above described character which may include a case containing the powder charge so as to form a cartridge having the usual primer or may omit the case and directly contain the powder charge to be fired electrically.
A further object of my invention is to provide a projectile as above set forth which can be used in any type of hand firearm, shoulder firearm either rifiled or smooth bore such as shotguns, ordnance and recoiless guns.
Still another object of my invention is to provide a projectile which is composed of separable sections of which a rear section has a sliding gas-tight fit in the bore of the barrel so as to be propelled therein by the gas pressure in the chamber when theweapon is tired, whereas a forward section which provides the bullet or shell, is supported clear of the bore by the rear section for unrestricted rotation on the rear section by the gas pressure in the chamber acting upon the forward section through the rear section, all in a manner to cause the forward section to be propelled from the barrel separately from the rear section with the correct amount of spin to insure accurate and true flight with minimum resistance and maximum velocity.
With these and other objects in view, my invention resides in the combinations, arrangements and functional relationships of elements as set forth in the following specification and particularly pointed out in the appended claims.
In the accompanying drawings,
FIGURE 1 is a fragmentary longitudinal axial sectional view showing the projectile embodying my invention in the form of a cartridge loaded into the chamber of a firearm;
FIGURE 2 is a view similar to FIGURE 1 and illustrating the projectile initiating its movement through the barrel immediately after firing;
FIGURE 3 is'a view similar to FIGURES 1 and 2 and illustrating the forward section of the projectile separated from the rear section thereof and clear of the muzzle end of the barrel;
FIGURES 4, and 6 are enlarged transverse sectional views taken, respectively, on the lines 4-4, 55 and 6-6 of FIGURE 1;
FIGURE 7 is a view of the projectile in side elevation; and
FIGURE 8 is an enlarged transverse sectional view taken on the line 8-8 of FIGURE 7.
Referring specifically to the drawings, my invention may or may not include a cartridge case C which is shown for the purpose of illustration as one embodiment of my invention comprising a projectile designated generally at P composed of a forward bullet or shell forming body section lit and a rear base or propelling section 11 on which the forward section is rotatably mounted yet is autorn'aticaly separable from the rear section following discharge of the firearm.
The rear section 11 is in the form of a cylinder the external diameter of which has a sliding, gas-tight fit at its end portions in the bore 12 of the firearm barrel 13, with the intermediate portion of the cylinder annularly grooved as indicated at 14 to reduce the area of frictional contact of the cylinder with the wall of the barrel bore. In the cartridge form of the invention illustrated, the base section 11 has a force fit in the front end of the case C and is assembled to the latter following the powder charge.
The body section 19 forming the bullet or shell is of elongated cylindrical form with a pointed nose 15. The rear end of the section 10 is provided with a relatively deep cylindrical pocket 20 forming a bearing co-axially related to the section and receiving a pin 21 providing a journal and projecting co-axially from the forward end of the section 11, with a close rotatable fit between the pin and pocket. Thus, the section 10 is mounted on the rear section 11 for rotation relatively thereto in parallel and coaxial relationship to the bore 12 and spaced from the wall of the bore as clearly shown in FIGURES 1 and 2.
The rear end of the section 11 is open to the interior of the case C by means of a conical recess 25 the smaller forward end of which communicates with an axial passage 26 extending into the pin 21 and terminating in a diametric passage 27 in the pin. The passage 27 opens at its ends to the periphery of the pin 21 adjacent to the rear end of the section It to provide nozzles co-acting with vanes or blades 28, (FIGURE 8) formed on the section 10 by slots 29 extending through the wall of the section from the pocket lit to the periphery of the section as clearly shown in FIGURE 8.
The slots 29 form gas exhaust passages, and their lengths extend tangentially with respect to a circle coaxially related and of a diameter approximately equal to that of the pocket 2%, all soythat each vane will be provided with an obliquely disposed working surface 30 against which the gases impinge upon leaving the nozzles. The forward section 10 is provided with a diametric passage 31 communicating with the pocket 20 at the bottom thereof to relieve the pocket of vacuum during operation of the invention which is as follows:
In the use of the invention without the case C, the recess '25 will contain a load of powder in solid form for firing electrically and will be of such capacity as to be capable of receiving a precalculated amount of powder. In the use of the invention with the case C seated in the chamber of the barrel 13, the bullet-forming section 10 will be mounted on the pin 21 of the section 11 as shown in FIGURE 1 and can, if desired, be maintained against axial displacement from the pin by magnetizing the end portion of the latter to magnetically attract the section It Upon firing the cartridge, the resulting gases will instantaneously travel through the passages 26, 27 of the section 11 and will impinge against the working surfaces 31 of the vanes 28 as the section 11 is ejected by the gases from the case C into the bore 12 as shown in FIGURE 2, so as to propel the sections through the bore and eifect rotation of the section 10 on the pin 21 in the direction of the arrow in FIGURE 5, by the action of the expanding gases against the surfaces 31 of 3 the vanes 28 as the gases discharge from the nozzles through the slots 29 into the bore 12 around the section 10.
Prior to reaching the muzzle of the barrel, the section 10 will have separated from the section 11, as the slight friction between the latter and the Wall of the bore 12 is sufficient to have very slightly reduced the velocity of the section 11 while the initial velocity of the section 10 remains unaffected by mechanically induced friction, to the end that the section 10 will leave the muzzle independently of the section 11 as shown in FIGURE 3, to insure accurate and true flight of the section 10 at maximum velocity.
From the foregoing description, it will be manifest that by eliminating rifiing in the barrel and utilizing the pressure of the powder gases to spin the bullet section 10, the resistance to movement of the projectile through the barrel is reduced to a negligible minimum by the relatively slight frictional contact of the propelling section 11 with the wall of the bore 12. Therefore, a much higher velocity with greatly increased penetration of a target can be obtained with a smaller amount of the most rapidly burning powder, all without generating the extremely high gas pressure necessary to overcome the high resistance of the conventional rifling to movement of a bullet at high velocity through the barrel.
It is to be understood that the terms bullet and bullet forming as used in the specification and claims are to be broadly construed to include any form of solid or explosive body irrespective of the type or calibre of the weapon from which it is fired. Furthermore, the propelling section 11 need not be a cylinder as it is only essential that it be circular at one point for a gas-tight fit in the bore 12.
