In a convenient embodiment of the pres-A ent invention, as shown in the drawings, a.,

is the. body of thegrenade, within the interior of which 4a housing b issuitably in cor- 2g porated, within which 4housing b a springimpelled striker c is adapted to operate. The cap which this striker 0 isadapted to fire is carried by a plug d which fits within the one extremity of -the central tubular housing b, said plug-d being rotatable in ref 4lation to the housing, and having, beyond the end of the housing, a U-shaped portion, or two arms, e, e' with 'an intermediate been assembled, afteruiwhiclithe tive y detonator, and fuse can be collec placed in position .without any diiculty or danger. The cap. plug is furnishedwith a shoulder Z or shoulders, which-limit the ex.- tent to which it can be inserted in the eentral housing; l

After the parts have been'assembled,l as. last described, the closure memberfm'is sembled. This closure member may be in the form of-a plug adapted to be screwed into the aperture in which the cup portion of the internal memberinvolving the housings b, is' screwed, the same screw-thread being employed. forthe cup .formation and for the plug,l .the cup formation 4being screwed inwardly. beyond the external surface of the body. Alternatively, the cu member, when screwed into place, 'may ave its externally screw-threaded surface projecting outwardly 'beyond the -external surface l of' the body, and acap may then 4be screwed groove or lateral opening, in the center of 3| which. groove is the aperture or perforation f leading to the-cap g. The one end of the time fuse la! canbe passed .into this centralperforation, and the fuse can pass laterally between the arms in eithervdirection toward 35 the `aperture or entrance to. the detonator housing z'. The detonatorliousing i may be integral withthe central housing b, and at the end of the. two housings there is a cup formation, within the plane of the edge of which the connecting part of the fuse is adapted to lie. The outer surfaces of the arms e, @,o'f the cap .plug d may be curved to form,- with the outer wall of the'cup, an an- ,45 cess, in rthe base of which there is a perfora- .tion oropening j leading to the detonator The fuse assing out of the perforation may,.f'instea of passing directly into the groove or 4opening in the cap plug, be con 5a tinued` around .this annular recess for any desired part of the circumference. and may then turn in toward the perforation f leading to the cap g, thecap plugbein rotated to an appropriate position to. provi e for this, as shown at Fig. 6.- Different lengths of time fuses ymay thusbe. accommodated to suit the requirements of.di i`erent periods.. of time l rwhich may be required to elapse between the.- operation .of the striker and the explo'- sion .of the'grenad'e. By reason ofthe cap without any screwing voperation, the' fuse plug "d beingV detachable and replaceable' nular or substantially annular groove or reupon the projecting portion of thecup member so that such- 'cap is screwed upon the same external screw thread as that by `which the cup portion is screwed into the spherical body of thegrenade. Ina'still further al 'ternative arrangement, the closure member m may be assembled by abayonet joint or other'suitable means of connection. The closure member m is adaptedto engage withthe outer face of thefcap plug and to retain the latter in position with its shoulder Z against the face ofthe ypart in which it is inserted. V'

If desired, I may provide between the closure members lm and the fuse, a washer or .protecting member, this washer or protecting.

member may be retained from rotation, asA for instance, by providing it with a projec- 105 tion adapted tocoperate with a notch provided in the'body of the grenade', and in such washer, in screwing .up the .closure member m, a purely axial pressure is applied tothe fuse, and cap plug, andtleatf. ter are relieved from.- the torsional stress which they would otherwise experience by reasonfof their frictional contact with the inner .surface of the closure member while' the latter is being screwed`v up. .The cap plug .d being rigidly retained in position by .the-closure member m constitutes C,an anvil u on or in vrelation to whichfthe c ap 4is struc and fired', b v the hammer. If'de-- 7LA eanibe assembled in relation tothe deto# nator'c and Gap plugd containing the cap 6 5 before eitherof the latter members have sired ,the portions e of the cap plug' may 1210-5 be` dispensed with, and the separable capjy plug instead of being retained in position by. the closure 'member`m, may be rigidly retained in position by other means, as, for instance, by a screw or screws engaging 125 with th'e'cap plug'and also withthepart by`\ which s uchplug is carried..

In order to satisfactorily secure the cap l d, and to prevent its beingTuShdout o f the latter inthe oper ation ofinserting' the use,1the "cap may, as shown-in lFigs. 1, 2 and 4, be furnished with arms -or extensions n, n, projecting through which proiestions fri may bejben't -outwardly at right anglesto lie within'the groove between the twoarins e, e, of the cap plu Or 'an equivalent'res-ult may be-.obtai'ne heading 'or expanding the edge of thetubular portion of the cap over t'e parts of the cap plug at f the lbottoni of y.the transverse lgroove Or at its inner extremity 4tlie cap plug may `be furnished around` its` circumference, or .atu intervals around' its circumference, 'with an annular Fig. 7, l.or with tongues, ribs, or projections, which, after the cap has been 'insel ,maybe contracted around orforc'ed inwtrlly. 'upon the head of the cap, to' therebyretainthe latter in its perforation, thel head being adapted to rest u on the innerjsur-face ofthe cap plug. 4If esired, sof retaining' the cap in. the plug may e adopted in connection with the. one cap.

The present invention permits of the cap,

fuse,jand detonator combined as introduced into,.and removedfrom,a Igrenade in orderto pr'o nuage, and thus the operca holder.

ations f of asseml be'carried out easily'. and safely.

Foralie purpose of releasing the sliding or longitndinallg-moving hammer .or striking member 0 wg ich incorporated withinthe intenall-iou'sing" b, and which hammer is .or .annular Haase' "adapted Q -tliebbdy-otthe grenade, such head orV i 'sind adapted to the s rface of the body a of -a point 'controlladby' a s i'i'itable'spring o, thehammeror striker 'maybe furnished with a head to project' out flange may be Vadapted to be engaged by the 'forked extremity of a lever g which liesv upon the grenade Such lever is -adapted to be disposed between two elongated projections or` flanges 1', r 'upon the outer 'surface of the body, and at near to the. head of the striker such flanges are form' bearings 'for trunnions or progections t provided one on each side orf 'the lever g.' When the ends s of the tail of the lever. q is retained against the outer surface ofthe body a, the forked'extremity on the lother side ofthe trunnions engages with 4the head or flange h of the striker o, and retains it in its retracted condition. pin'u may lb e 4assedthrough the flanges between which t clever g lies, such pin occuying a position. above or outside of the ever to retain the latter in; this positiokrli. t e

ling'tliev various 4parts can extends .a distance around the latter.-

furnished with slots or grooves .tail of the lever is retained against the body la by han or 'by 4the thrownap -the pin'u is removed, the grena e isft wn', and upon the grenade being released-bythe hand or throwing ap liance, the lever q'by a pivotal movement, re eases the striker, =wh1ch latteiiires-the cap.

'The lever may, if desired, be,'as shown in Figs.' 8' and 9, applied to a handle with which the grenade is furni'shed. In Fig. 8, thel tubular housin y or cont'aining the spring-impelled stri er o is contained within the handle. The anvil w which corresponds with the cap plug d, in Fig. 1, isseparable and removable, but. is rigidly retained fro'm axial displacement between the housing y for the striker, and the detonator housing e, beingr disposed in a hollow extension of the handle in the arrangement shown in Fig. 8, and within the enlarged extension of the detonator housing in the arrangement shown in Fig. 9.y The housing y for the striker constitute-s or is provided with the handle, and suchl housing of the .striker may be screwed4 into an enlarged 'extension of vthe housings for the detonator.' which enlarged 'extension is in turn lscrewed into the hollow body of the grenade. 4

Any suitable means may be adopted in the' arrangement 'shown in Figs. 8 a1id 9 for. retaining 4the time fuse in appropriate relationship -to the cap, 4s o that it shall not be blown out upon the liring'of the latter. NFor this purpose the 'time 'fuse may be shot lacked--i'vithin orin relation to 4the cap er anvil m, or intf-rnalV Vpoints or proieetions may be provided -upon the Acap or anvil adapted to engage with the external surface of vthe time fuse, and. so' reta'iiiztlieV latte-i' from axial movement.. 'As in tlie .case 4previously described, the cap d, anvil ai, `fuse e, and "detonator g'can be collectively inserted or 'removed when 'the handle is detached.

.In connection with the .present invention I may' employ the invention comprised in my prior patent, Soy-1,178,092, but I donot in this application make any` claim to anything claimed in in v said concurrentrapplif cation. i vWhat I claim as my invention 'and desire.
