Specification of Letters Patent.
Patented Mar. 18, 1919.
Application filed October 17, 1916. Serial No. 126,072.
To all whom it may concern:
Be it known that I, DINO CI-IIARAVIGLIO,
" a subject of the King of'Italy, residing at 102 Via Nazionale, Rome, Italy, have invented certain new and useful Improvements in or Relating to Firearms, of which the following is a specification.
This invention relates to multicharge fire arms, in which two or more charges are arranged in chambers orginally separated from each other and act separately at suitable intervals of time, for the purpose of transmitting in the best possible manner the energy of the explosive to the projectile while it is passing through the barrel.
The invention comprises a new arrangement of the partial propelling charges in V multicharge fire arms, and is illustrated in the accompanying drawings, in which:
E (Figure 1) is the wall of a muzzle-loading gun, A the projectile, which,-instead of having a practically flat base, is provided with an extension B which engages in a suitable recess provided in the breech F. In this way two chambers C and D are obtained, in each of which is placed a propelling charge. More chambers for additional propelling charges could be obtained by an equal number of restrictions in the diameter of the extension B, as shown in Fig. 2. The communication between the chambers C and D (Fig. 1) is established by means of a small conduit -ef-- of suitable size, in which can be located a fuse, the speed of combustion of which has been suitably calculated.
If one of the charges, for instance that at D, is fired through the touch-hole --g, the ignition will spread to the other in a manner determined by the size and shape of the passage 6], or by the speed of combustion of the fuse. By giving the various parts suitable dimensions, it is thus possible to insure that both charges should begin or cease to act at different moments.
The ignition of the different portions of the charge could also be regulated or produced by the movement of the projectile; it is also possible to arrange the charge so that each of its separate parts plays part in the movement of the projectile. Moreover, muzzle-loading or breech-loading arms could be designed in which the obturator constitutes a part of the walls of one or more charge chambers. The arrangement could also be such that the projectile contains the whole or a part of the propelling charger Fig. 3 shows an. arrangement as could be 7 i adopted in breech-loading guns. The two propelling charges are contained in a metal casing -m in which the projectile is firmly inserted. To load the gun firstly the breech 0 is taken apart by unscrewing it from the rest of the gun, secondly the projectile is inserted ,with the casing -mcontaining the propelling charges, attached to it; the breech is then screwed up again in position, and the gun is ready to be fired by striking the striker p which will explode the cap'g and thus set fire to the first propelling charge. The second propelling charge will be exploded by the gases of the first charges passing through the passage cf, or by a fuse located in said passage, or directly by the gases of the first charge as soon as the extension B of the projectile has moved far enough to allow the gases of the first charge to come into direct contact with. the second charge at D.
As above described and shown by the drawings the invention mainly consists in obtaining the different chambers for the propelling charges by modifying the shape of usual projectiles and particularly by means of a rearward extension of the projectile; therefore such chambers are not prepared in the gun or in a cartridge except in the case of Fig. 3, but are originated by the projectile itself at the moment of its insertion into position in the barrel of the gun. An important feature of this arrangement is that the walls of the gun are also the walls of the charge chambers; thereby doing away with the necessity of separating the difierent chambers With a sufiicient thickness of metal to stand the strain produced by each of the propelling charges acting separately, as is the case with many of the similar arrangements hitherto known. Another important advantage of my arrangement compared with others is that the intervals of time at which each of the propelling charges begins to act can be' perfectly regulated either by proportioning in the right way the size of the passages from one chamber to the other, or by suitably regulating the speed of combustion of a time fuse or finally by proportioning the charges and the dimensions of the gun in such a way as to make the gases produced by the combustion of each charge come into direct w r rm ld f h n' tur of my tai nt n n "per contact with the succeeding charge at the right moment, determined by a particular position of the projectile-"in: itsforward movement along the barrelof the gun.
The arrangement described has also the advantage of being very simple in construction and thus capable ot a very easy application, and of permitting a Very, strong and comparatively light construction of the gu'ri, owing to the fact thattheqharge chambers are not preparedin' the gun 'b'arrehb it are originated by the peculiar shape oi tliefpro jectilefjvhen this is injpositioni in the, gun,
and that'the Walls 10f the gun also Walls for an" the charge chambers.
