To all whom it may concern:

Be it known that 1, CHARLES VALENTINE RINEHART, a citizen of the United States,

. for the timed release of missiles including propelling charges of their own, either with or Without the, usual shrapnel ball.

The other objects, relating as they do for the most part to the manner and means employed for the above purpose, together with the advantages resulting from the several objects, will more clearly appearfrom the following description of the invention, reference being made to the accompanying drawings, illustrating at least two of the forms in which it may be incorporated, and wherein:

Figure l is a central longitudinal section through a projectile constituting one form of the invention.

Fig. 2 is a'transverse section therethrough taken substantially on line 22 of Fig. 1.

Fig. 3 is a view partly in elevation and partly broken away and in section of the base portion thereof.

Fig. 4 is a view similar to Fig. 1, illustrating a modified form of the invention.

Fig, 5 is a detail gerspective view of a portion of the firing olt shown in Fig. 4. Fig. 6 is a cross section therethrough taken substantially on line 66 of Fig. 4.

Fig. 7 is'a longitudinal section taken substantially on line 7-7 of Fig. 6.

Fi 8 is an elevation of the shell shown in Figs. 4 to 7 inclusive.

Referring now to these figures, my invention contemplates the employment of a shell the body 10 of which is cylindrical and conformable therefore in size and shape to the approved forms now in use, and a cap 11 similarly conforming to the approved type and provided as usual with a concussion plunger 12 operating against a pin 13 to ignite the timer 14 from which the time train is fired, a portion of such time train being carried in each of the rings 15 and 16 as seen at the points 17.

The shell body is encircled near its base by the usual copper ring 18, and is, in accordance with this invention, provided within the base with a fixed disk 19 secured therein and spaced from the base of the shell'body 10 as seen at 20, to form a chamber 21 for the reception of a bursting charge, the disk 19 having a hub portion 22 extending rearwardly into contact with the shell base 20 and providing a forwardly opening cylinder 23 in which is a propelling charge 24 connecting, through a fuse 25, with the time train of the cap 11.

Within the body 10 forwardly of the disk 19 is a fixed core 26 having a plurality of rifled bores for the reception of cartridges 28 corresponding in number of course to the numbers of the bores, the firing of which cartridges is accomplished through means actuated by the propelling charge 24 before mentioned.

In the form of the invention as shown in Figs. 1 to 3 inclusive, the several bores 27 of the core 26 are arranged parallel to the axis of the shell and the cartridge bullets are therefore propelled forwardly, for which purpose the head or cap 11 is provided at its inner surface and at a central point, with an unmasking charge 29 located in a recess in the cap and communicating with the time train 17 through a shortfuse 30, the unmasking charge in turn communicating with the forward end of the fuse 25, the latter extending axially through the core 26 and through a tube 31 projecting rearwardly from the rear end of the core.

Thus, when the time train burns to the short fuse 30 and ignites the unnlasking charge 29, the cap 11 is blown away from the shell, a resistance disk 32 being disposed against the forward end of the core centrally thereof and around the forward end of the fuse 25 to receive the impact of explosion of the unmasking charge 29. Thus the forward ends of the several bores 27 will be exposed to permit free passage of the cartridge bullets when the cartridges 28 are exploded.

Abutting the rear end of the core 26 is a 'disk 33 rigidly fixed in the shell body 10 and spaced forwardly from the disk 19 before mentioned. disk 33 having a plurality of apertures 34 registering with the rear ends of the bores 27 of the core 26 to receive firing pins 35. the latter having safety flanges 36 against the rear surface of the disk 33 which are sheared upon forceful impact against the rear ends of the firing pins to drive the latter forwardly through the opening 34 and against the cartr1dges 28 and the space in the rear of dlsk 33 having a vent 36".

Thus, after the unmasking charge has been fired as before described and the cap 11 sistance plate 32 drops away from the front end of the core 26, the fuse 25 fires the propelling-charge 24 in'the cylinder 23, acting against the piston 39 of the disk 38 to force this disk forwardly, shearing the resistance or safety wires 40 extending transversely through the guide bolts or pins 37. The disk 38 thus moves against the rear ends of the entire series of firing pins 35, driving the latter forwardly in the openings of the disk 33 and againstthe several cart-ridges28 and exploding the latter in order to drive the bullets thereof outwardly through the bores 27.- p

The chamber 21 as before described may contain a bursting charge by which either the shell is shattered after striking or at a desired time, and for which purposeI have shown a separate longitudinal fuse 41 in Fig. 7, the rear end of which communicates with the chamber 21 containing the bursting charge 21", and the forward end of which communicates with a portion of the time train17 in Fig. 7, parts of'which are car-' ried in two movable rings 15 and 16 in this instance, by the relative adjustment of which the tune of firing the fuse 41 may -be controlled the same as the firing of the central propelling charge fuse 25 is controlled.

In the form of my invention as shown in Figs. 4 to '8 inclusive, the central ,fuse 25 extends axially through a firing bolt 42, the latter in turn movable axially of the shell body 10, witltrits rear flanged end 43 acting as a piston within the cylinder 23 of the hub 22 of disk 19, simi er in construction to the disk 19 before described and having avent 23". v The core26 is in this instance, as best seen in Fig. 6, com osed of a plurality of radially extending ri s 26", each rib having a longitudinally series of bores 27 inclined forwardly and outwardly, these bores being rifled similarly to the bores 27 before I described, and communicating at their outer ends with conformable openings 10 inthe shell ,body 10, so that the cartridges 28 located-within the inner ends of the bores- 27 will be discharged through the openings 10 of the casing or shell body, thus obviating the necessity for unmasking the front end of the shell, as in the form of the invention previously described.

The. core 26 of the shape just described thus provides for axial movement of the firing bolt 42, the latter of which has clusters of radiating barbs 44 in its length alined with the. inner ends of the several cartridges 28, so that when the bolt is propelled forwardly the several cartridges will be dis charged. The particular shape of the core 26 also provides triangular spaces as seen at 26, particularly in F 1g. 6, between the ribs 26 and the inner surface of the shell 7 body 10, to receive longitudinal series of blown 03 of the shellfatwh'ich time the rethe rear end of the core 26 is closed and forms bearing points centrally thereof for a resistance or safety flange 46 of the firing bolt 42, which is sheared when the propelling charge 24 within the chamber 23 is discharged, or rather, ignited by the fuse 25*. It is obvious, however, that in either instance I secure the timed release of missiles having propelling charges of their own, and that this may be done according to my invention either with or without thensual shrapnel balls and the usual bursting charge and timed in relation to the timing of the firing of the bursting charge through the dual timing arrangement, seen best in Fig. 7, and as previously described.

It isobvious that my improved projectile covering the center of the target.

It'will be further noted by reference to Fig. 6 that the core 26 is segmental each segment being a tapered inner portion of one of the ribs 26 and that these segments of the core have slots extending longitudinally and in Which'the several barbs 44 of the firing bolt inner ends of the several bores 27*.1
