I
Further objects of the invention are to provide a projectile for the purposev set forth which is comparatively simple in its arrangement and construction, eflicient in its use, having means to automatically provide for a successive series of impulses during the flight thereof to obtain an extremely long range therefor, and comparatively inexpensive to manufacture.
- With the foregoing and other objects in viewftheinventlon consists of a novel construction, combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown the embodiment of the invention, but it is to be understood that changes, variations and modifications can, be resorted to which. come withinthe scope of the'claims hereunto appended.

Figure 10, is a detailed transverse section through a firing pin body and detonati'ng:
- which constitutes an is designed to contain will crush over the nose and through a slightly modified form of projectile.
Referring fmore in detail to the accompanying drawing the numeral 1 designates the bullet, which may be solid or ofthe shrapnel or gas-filled type, and 2, 3, 4, 5, and 8 a are theindependent impulse elements propelling explosion chambers which form, with the bullet 1, the complete projectile, the same being mounted'within the shell 6 which is to contain the charge for the initial discharge of the projectile from the cannon 7. The shell 6 is here shown as being disposed within a cannon 7 ready for being fired. .That portionof the wall of theshell 6 surrounding thecharge,v for initial dis-' charge of the projectile, being thicker than that portion of the wall of the shell 6, which surrounds the impulse elements or propelling explosion chamber, and by this arrangement an annular shoulder is provided annular seat for the baseofthe projectile when ,mounted in the shell 6.
Each of the propelling explosion chambers 2, 3, 4-and- 5 comprises a cylindrical body end counter-bored to pro-' having its forward vide an internal shoulder or seat for the next a forward chamber, the chambers 4, 3, 2, and
8 having their rear portions reduced in di--, ameter so as to telescope or nest within the next succeeding chamber'andengage on the internal shoulder thereof. Each chamber an-explosive which when fired, will impart an added impetus or acceleration to the preceding projectile section. Throughout its flight the projectile will be intermittently boosted through the successive explosions of the chamber, the final charge in chamber 8 serving to explode the main charge in the bullet 1 unless the latter shall strikeits object previously thereto in:which latter instance a pointed cap 9 on the forward end or nose of the bullet drive the firing pin 10, carried by the cap 9, rearwardly to explode a primer 11, the pin 10 extends into the bullet 1 to within a short distance of the primer 11,-the latter is fitted into a recess formed in the inner end of a hollow plug 12", which is filled with an explosive charge and connects the primer 11 with a more powerful primer 13, mounted 'in a'flanged perforated thimble 14 which is secured in a ,threaded collar formed on the plug 12." The purpose of this arrangement is to cause the exploding of the main charge in the explosive bullet, in case the bullet strikes a target before the explosion ofa charge in a detonating chamber, which is connected 'with and communicates with the bullet at the rear end of the latter. This detonating chamber will be presently referred to. When the charge in the plug 12, is ignited by the primer 11, the primer '13 is operated, to
charge 29 in the holder 28.
mamas ignite a detonating charge 53 contained within a cylinder 15 and finally exploding the main charge 54: of the bullet. Obviously the bullet will explode whether it hits prematurely or not, and by the proper timing of the several explosions the bullet will explode during its flight even if it has not hit its I object. The main charge is confined within the bullet 1 by a perforated plate 16 closing its rear end.-
The impulse or '75 I propelling chamber 8, is also what may be termed a detonating chamber, is constructed similar to theother impulse elements, except that the sleeve'wh-ich projects forwardly and which is indicated at 8, is threaded for the purpose of attaching it to the rear end of the bullet 1, and further that its cover plate 58 is perforated. The
purpose of the impulse element 8, is to detonate or explode, through the perforated '85 :plates 16 and 58,the main charge 54 in the 'bullet 1, just before the latter reaches its target, in case an explosive bullet, as illustrated, is used. 1
Within each'i-mpulse elementor propelling explosion chamber, is fixed a firing pin body or guide 18, in the form ofatube having a flared inner end seated in a recess in the rear wall of the body of the element. 'The firing pin body or guide 18 has its outer end i also flared, and the said outer end is engaged in an annular recess formed in the. closureplate 41 of the element.
' The firing pin body 18, near its forward end isprovided with a firing pin 25, formed with a peripheral annular groove to receive the-pointed inner end of a plunger or trigger, and which when engaged in the groove of the firing pin 25, retains the latter in position against the. action of a coiled spring 26- which has its forward end held by a pin 40, mounted in the forward end of the firing pin body 18. firing At the rear endof the pin body 18, is a fuse ignition chamber containing a hollow double flanged holder 28, no for a primer 27, which ignites a powder At the rear of the holder 28, andwithin the same, is arra a fuse retainer 35. Fixedly connected to the rear of the fir as well as opening into the ignition chamber formed at the rear end of the firing pin body 18, are a plurality of bent tubes 31, referably four in number, andthrough which extend fuses 30, these latter pass through the wallof the ignition chamber in the firing pin body 18 and also through .the wall of the chamber in the holder 28, in which is mounted the fuse retainer 35. The ends of the fuses are split, to expose the combustible carried thereby and the split' end of each fuse is spread apart and extended in a longitudinal groove on the periphery of the retainer 35. The number of grooves on they periphery of the retainer 35, equal the, num
The fuses extend throughout the length of the tubes 31, and terminate in contact with primers 34, which are disposed around the firing pin body 18. The primers 34 are contained in the perforated and threaded primer thimbles 33. A spacing ring 32 is provided for the fuse tube and primer thimbles, and which is clamped between the threaded bell on the end of a primer thimble and an annular shoulder near the threaded end of a fuse tube.
Disposed at right angles with respect to the firing pin body 18 is a cylindrical guide 19, which is held securely in position by having one end fitting tightly into a socket 4 in the body 18 and its other end mounted in an opening formed in a stay plate 20. The
guide 19 has mounted thereon, a shiftable sleeve 38 and arranged within the guide 19 is. a spring controlled plunger 24, which' at' its inner end, extends into an annular groove formed in the firing pin 25. Plunger 24 is held in engagin position with the firing pin 25, against t e outward pressure of the spring 46, by a segmental locking block. 37, in the guide 19 and engaging in a groove 45 formed in the plunger 24. Removably attached to the outer end of the plunger 24, is a stud of a tapered intermediate extension pin 23 carrying an outer extension pin 21 the latter is of such a length as to extend into'the tapered opening 22 formed in the wall of the explosion chamber.
The stay plate 20 is curved to fit the inner wall of the explosion chamber and serves asa support and loeator for the guide 19. It is held in place, at its forward end by the engagement of its bevelled or dove-tailed edges, with similar bevelled edges 45 of a notch cut through the-shoulder 42, on the inner wall of the explosion chamber. The
' rear end of the stay plate 20 is held in po-- sition, through the medium of a pair of studs 44.
ner end of-the guide 19 and interposed between a shoulder on said guideand the firing body 18.
plosion chamber, and pin 21 is inserted through the hole 32. The base of the explosion chamber is then-inserted and pressed back into the bell or apron of the explosion chamber adjoining at-the rear, the air esof cover plates 41, 58,thence into the annular groove 47 and thence through the ports 38 in the outer wall. 7 j
The extension pin 21, when the parts are in the position referred to, has a bearing against the wall of the bell of the adjoining chamber, and provides what may be termed a secondary support for the plunger 34, thereby holding it and the firing pin 35 securely in place and as long as the two explosion chambers or impulse elements remainin the same relative position.
After the parts have been assembled, in the man r, as referred to, the sleeve 38 is pressed back against the action of its spring 39, and the locking block 37 is' then removed, after which the sleeve 38 is returned to its original position closing the slot formed by the removal of the block 37 The explosive charge 56 or 5, is now packed into the explosion chamber and covered by the fabric. 43, and also the cover plate 41 or 58.
The impulse element'or propelling explosion chamber 55, as it does not seat in an impulse element at the rear thereof, must be provided with a device to coact with the extension pin 21, and the device, as shown, consists of a release block 5 0,'fitted into a slot or pocket in the outer wall of impulse element or propelling chamber 5, and said vide-a support for the block 50 until the latter'is engaged by the wallpf the shell 6.
Soft ,metal powder rings intended to engage the rifie barrel of the cannon, are indicated at 51,52 and 57.
In operation the projectile is first fired from the cannon by the initial explosion of the charge .in the shell 6, asthe projectile travels out through the barrel of the cannon, the release (block 50 bears against and retained in place by the wall of the barrel. On leaving the muzzle of the gun or can- "non; this. block 50 and the outer extension pin" 21 oif, due to the action'of the plungerspring 46- forcing the plunger 34 out-- wardly to the position shown in the dotted lines, Figure 5. This action of the plunger 34,-forces the tapered pin 23 in the opening 22/ completely closing it. When the plunger v spring 46, forces the plunger 34 outwardly, it causes the release of the firing pin 25,
which is driven back by the spring 26, to the position shown in the dotted lines in Figure 5. The air contained in the firing pin body 18, is free to pass forward, through the prot-ion of the powder charge 29and fuses 30(i are free to escape through the perforate flange of holder 28, through the tube, of the firing pin body 18, thence through the ports of the firing pin 25, a center 'opening in theplate 41, into the space forwardly of the plate 41, thence through radial openings in the inner and outer flanges of the late 41, into the annular groove 47 forme the explosive chamber, through the ports 48.
. The fuses 30, burning at their other ends ignite the detonating primers 34, which explode the charge 56 in the impulse element or propelling explosion chamber 5. The explosion of this charge exerts its force in all directions giving an'impetus or boost to the velocity of the forward part of the projectile and stripping off the propelling. explosion chamber 5 from the adjoining propelling' explosion chamber 4, thereby uncovering the extension pin 21 of the propel-v ling explosion chamber 4, when the foregoing described operation of firing is repeated,
as well as, in connection with propelling explosion chambers, 3, 2 and 8.
With reference to the modified form shown in Figure'12, the difference withro spect to the construction shown in Figu 2, is that a tube is fixed to the bullet on the forward end vof the projectile, which tube is to serve as a barrel chamber, from which 1 each succeeding impulse element or thepropelling explosion chamber will be discharged, the purpose being to better utilize the force of such propelling explosion, by
confining the compressed gases behind the:
projectile for changing the time for the sections being ejected as the flight proceeds. It will be noted further that eachimpulse element or propelling explosion chamber from the rear chamber indicated at 5,has a-gr'eater distance to travel before leaving theend of the tube, and the presure of the gases against the part of the projectile remaining would therefore be elfected to a regular'incre'asing time interval, as the initial velocity 'of'the projectile expended itself.
It will be dbserved that ineither form a projectile is provided which will be accordtelescoplng chamber, charge firing means" ed added impetus" or boosts at regular inin the Wall of and discharged.
