EXPLOSIVIF PROJECTILE.-

priming characterized by a priming holder in the head of which a flame passage block is arranged the latter being furnished with a central passage charged with compressed powder or mealed powder and with one or more slightly eccentric passages charged with mealed powder or compressed powder. In the various constructional forms described in the specification of the said application for patent the head of the priming holder is screwed into a socket formed in continuation of the body of the fuse, its bottombeing perforated with an axial passage communicating with the body of the fuse in such a manner that the Variable screwing of the priming holder into the socket causes an obtorator (which may either be free or rigidly connected with one of the elements) to render the direct passage free for the flame or to obturatethis passage to cause the flame to be transmitted through the conduit or conduits charged with compressedv powder. The obturation ot' the communication between the fuse and the directtransmission conduit of the flame passage block is thus obtained by bringing together the priming holder and the bottom of the fuse body; COILVBISQLV a separation of these two elements (bottom of the fuse body and head of the priming holder) renders the direct communication free.

The present invention has for its object two modifications of a particular construction of the aforesaid invention.

According to the present inventionthe head of the priming holder is attached to a detonator body which is screwed into the projectile, the body or the fuse having its bottom perforated with a" communication Specification of Letters ram.

passage and being screwed into a detachable or absence of which indicates respectively that the projectile is adjusted for direct transmission of the Home from the primer or for retarded transmission of the fiame.

In order that the said invention may be more clearly understood and readily carried into efiect I will describe the same more fully with reference to the accompanying drawings,.in which Figure 1 is a longitudinal section ofone of these constructions the parts being ar ranged for the directtransmission of the flame and a key for unscrewing or screwing .the ogival head being represented fitted to the latter. Fig. 2 is a partial-plan view of this key. Fig. 3 is a longitudinal section similar to that in Fig. 1 and showing the parts in the posit-ion for retarded operation. Figs. 4 and 5 illustrate in sectional elevation and in plan respectively a detachable collar in two pieces. Figs. 6 and 7 show in longitudinal section a second constauict-ion the parts being represented respectively in posi tion for direct operation and for retarded operation. ,1

The novel constructional forms comprise apriming holde'r 7 iurnishedwith its det' onating primingS and at the'center of its head 6 a flame passage block-s ,is screwed; the latter is perforated with an axial passage c and one or more eccentric passages b communicating with the axial-passage. The axial passage is free or charged with mealed powder while the lateral passage is charged with compressed powder as shown in Figs. 1 and 3; or the lateral passage is free while the upper part of the axial passage 0 above the point at which the lateral passage 1) opens in charged with compressed powder as shown in Figs. 6 and 7 Communication between the ruse and the ireta passage may be interrupted by fitting a projection 3 carried by the bottom a of the tusc body into the upper part of the axial passage (3 in the example illustrated in Figs. 1 and 3; or by fitting a )rojection P. from this upper part of the axial passage into the communication passage 2 in th' l bottom a of the l'u-' body as in theexample I illustrated in hi 1 and T.

One point of di lcrcme between the pres I ent coustructiomd forms those of the aforesaid application for. out is that the priming holder is not screw .l into the body oi the fuse. The head ti oi the priming holder 78 is screwed home into a detonator body 9 which is itself screwed into the egival head of the projectile. The t'use body 1 having its bottom a pet ated with the communication passage if is screwed into a separate ogival head which may itself be screwed more or less deeply into the projectile this screwing to a greater or less depth enabling the obturator 3 to be titted into its housing for interruptingdirect ignition or the release of this obtiirator for cstablishing direct operation. Another characteristic of the present construction is the interposition between the ogival head carrying the fuse and the face of the projectile (in a housing 13 formed in the said ogival point) of a detachable collar of a dilferent metal, the presence of the collar thus indicating visibly that the projectile is usted for the direct transmission of the flame of the fuse to the priming holder; the absence of the collar on the other hand indicating immediately that the shell is adjusted for retarded operation. The detachable collar is made in two or more parts being sh own in two parts 11 and 12 for example in Figs. d and 5; this collar is preferably angular in cross section. The horizontal branch is intended to be compressed between the projectile and the ogival head 10,- the vertical branch of the collar enters the projectile. An unscrewing key 14; (Figs. 1 and 2) comprises two noses 1.5 which engage in notches 16 in the ogival head 10. The detonator is mounted for the transmission of the flame (that is to say with the detachable collar ompie...ed beneath the ogival point) for transport in the colters or bins.

in order so bring the detonator into the position for rclari'icd liring it is only necessary to llllstfl'CA' the ogival head by one or more turns; the detachable collar is released automati ally by this operation; it is then only new y to allow the fragments of which the collar is composed to fall, Whereupon the ogh at head is screwed right home. The latter operation drives the pin 3 into its housing whether it is carried by the bottom ol the lose or by the llaine passage block.

The detonator adjusted for retarded transmission of the tlame may readily be adjusted for direct transmission. Inthis case the detachable collar is replaced beneath the ogival head. The operation of modifying the retardation is thus reduced to two ex- 5 .z-codin lv sim le oierat-ions' l unscrewtransmission,

llame of ignition and ing the ogival. head by one or more turns and (2) screwing the said head home.

As stated above the detachable collar being formed of a difierent metal from that of the body of the shell and of the ogival head mere inspection of the shell will indicate for what position the retardation is adj usted.

IV hat I claim and desire to secure by Letters Patent of the United States is 7 1. In combination, a projectile body, a. removable head, two passages provided in one of said partsone for direct transmission of the flame of ignition and the other for retarded transmission, a priming holder mounted in said body, a fuse mounted in said head, and connections between said head and body whereby the former can be moved to obturate one of said passages.
