To all whom t may concern.' x Y Be it known that I, vMARCUS O. ANTHONY, a citizen of the United States, residing at New York, county of New York, Stat-eef New York, have invented an Improvementin Grenades, of which the following description, in connection vwith the accom# panying drawing, is a'specication, like characters on the drawing representing like parts. v
This invention relates to grenades, and has for its object to provide aV novel grethel grenade is ired by driving the primer against said stationary pin;y to provide ,a grenade in which the hammeris, held in' its inoperative position by' a thrust pin that is interposed between said hammer and the controlling lever or handle; to providea novel firing mechanism which lis compact) and which can be removed from or placed in the grenade .body asa unit and after itha-s been set, and otherwise' to iimprove grenades Y allas will be `more fully hereinafter lset vforth. p Y i In order, to give an understanding of my invention, I have illustrated in' the draw'- ings a selected embodiment thereof which will now be described after which thenovel features will be pointed out in the appended claims. Y Y
Fi urel is a side view of a bodyingthe invention ;v
Fig. 2 is a sectional view;
grenade em- Fig. 3 is a fragmentary sectional viewr similar to Fig. 2 but showing the holder inl side elevation and the parts'in the position they assume when the hammeris released, and -A v Fig. 4 is an enlarged section on the .line 4-4,' F ig. 2. n
The grenade comprises a grenade body l, which may have any` suitable construction and is adapted to` contain the explosive material 2, and the novel iiri'ng means which constitutes-the principal Yfeature ofV my invention. This firing means is of that type which comprises a primerwhich whenvexplodedignites a useleading to a detonator, a hammer for vexploding the primer anda l` controlling lever orY handle by which` the operation of the hammer is Controlled,
In my invention the operative parts of the firing mechanism are carried by a support which is detachably seouredtoy the within the Vhead `5.
Y the fuse13 leads.
grenade body so'that said firing mechanism can be assembled'andy set and'then applied--v as-aunit'to the grenade body.V F urther-v more, in kmy firingv mechanism thefiiring pin is stationary` and the exploding of the'f primer is accomplished bydriving it against lthe firingpin. This is provided for bysup#l porting the primer in a movable holder and i employing a spring-impelled hammer `for driving Vthe holder toward the firing pin, the operation of the yhammer being con-v trolled by the controlling Ylever or handle.`
The support or carrier for the firing means isvherein shown as a sleeve rwhich isV screw-threaded through the neck 4' of the loodyl.` This sleeve projects beyond the body land a head'r is secured to the pro-Y jecting end preferably'v by being screwed;
thereto. Said head is provided with a pro? jection 6 which is situated Vat the outer end', oi'the sleeve 3,k and which .forms a stationary, p ring pin, andingthe illustrated embodi' ment of the invention` said projection is Y formed on a` steelplate which is located.,
Lo'oseiy Situated within the sleeve v: isi a holder? for a primer .9, said holder hav#` ing Va primer-receiving opening 8 .in'linew witlithe firing pin 6 and in which the primery 9 is placed.V y Y K The sleeve- 3 is provided near itsend with a shoulder 31 and the' holder 7 is formed with a flange 32 to, resten the shoulder, said holder being free to move-in the sleeve toward the firing pin 6. Y A Y f A time fuse 13. is situated within the sleeve 3 and is heldin place by crimping-the sleeve intermediate of its'ends,` as. shown at The inner end ofjthe sleeve has anenlarged bore v`and receives a. detonator 12V intowhich f I will `preferably con-..
structk the detonator so lthat afterlthe"fuse,L
is crimped intoVY the tube or sleeve '3,' the@ detonatorl2. can be, placed in Vthe lower end-u of thejsleeve and slipped over'the end of.'V the fuse. A- rubber plug34'serves to. holdf` the detonator in place. f A spring-impelled ico hammer is providedjf' for drivingrthe holder toward the firing-:ivV`
thereby to force the primeragainst said; pin whenyit is desiredto @operate ther` grenade. l Y y The hammer for,` driving the ho lder 7 yto-iTV ward the firing pin Vmay have any-suitable'.
construction. Iyrhave herein shown it.; as ag) lio.
l shown. as integral Vwith the hammer.
ring 14 which is slidably mounted in the sleeve l3and is acted on by a spring 15 confined between the hammer and a shoulder 16 on the sleeve-3f.A y
The spring l15A thus tendsV to VJforce vthe hammer toward the holder, and said holderV by a thrust pin '19 interposed .between the handle and hammer and which is heein he lever or handle 18 has a vportion 20 which overlies the head 5 and is provided with a nose oribeak 21 adapte'dto engage a loop 22 JformedY on said head and also another` portion 23shaped to conform to and overlie the sideof the grenadebody. Said handle is also provided with perforated ears24 adapted to straddle an apertured projection 25 on the head, the construction being such that when the apertures in the ears and projection are in alinement a pin 26 may be inserted through 'the alined'lapertures thereby kto retain the handle in its operativepo-Y sition.l Thef pin 19 occupies a slot 39 formed in the holder 7 and extends through the head 5 and bearsagainst the portion 2O oit the handlel 18, said pinV operatingto hold the hammer in its retracted position with the spring 15 compressed. 27 is a sheet of packingmaterial such as leather or waxed paper which is interposed between the portion 20 of the handle 18 and'thehead 5 for the purpose ofmaln'ngla water-.tight joinslv at the point where the pin 19 1s locate It will be noted that all the parts or" theV :firing mechanism are carried by the support 3 so that the firing means can be removed fromor applied to the body 1 as a unit.
In assembling the parts of the mechanism the fuse is iirst inserted into-the sleeve 3 and the latter is crimped at 33 thereby to secure the fuse in place. The vspring, 15 and hammer 14 are then inserted into the Sleeve and the holder 7 with the primer 9 therein is put in place. The handle 13 is thensecured to the head 5, the water-proofing packing 27 having been inserted between the portion 2O of the handle and said head,
and the head with the handle secured there-V the tiring mechanism which may then be `screwed into the body 1 and they latter filled with the explosive charge 2 through an opening 35 in itslower end. lA plug 36 closes the opening 35, said 'plug having such a size that when it is in place it-engages the plug v34 so as to retainithe latter in place.
It will be noted that the lower end ofthe sleeve 3 which contains the detonator is situated closely adjacent and inline with thel opening 35 in the body. It will also be noted lthat the detonator is constructedk so that it .to Vthe body k1 and the latter can be supplied withv its explosive charge 2.- They rubber plug 34 will prevent the explosive charge from entering thelower end of the sleeve 3. rIhe grenade thus prepared may then bel shipped to the ield of operations or stored,
Y the detonators being shipped or stored separately. When it is desired to use the grenade,it-is simply necessary to remove the two plugs 36 `and 34,l insert a detonator into the lower end of the sleeve 3 and then replace theplugs 34 and 36.
The grenade without" the detonator lis comparatively safe to handle and grenades thusl prepared can be y shipped in large quantities without danger. The 'detonatorsl can also be readily shipped separately with- Vout particular danger, and the task of completing the Vgrenades by insertingthe detonator on the ield of operations is a simple one. f
In using the grenade, the operator places it in his hand with the handle 18 against the palnlV of hishand and then withdraws the pin 26. The grenade is then thrown and as soon as it leaves the'operators hand the expanding force ofthe spring 15 willV throw the hammer forward, thus causing it to strike the shoulder 17 and drive the holder 7 toward the firing pin 6, such movement of the holder bringing the primer 9 against said ring pin with sufficient `force to explode it. The exploding of the primer ignites the fuse-13 which in turn Vfires the detonator 12 and the latter explodes the main charge in thegrenade.
Some hand grenades are provided with peripheral flanges 41 designed to fit the bore of a trench mortar so as to provide for iring said grenades from such a mortar. In order to adapt my improved grenade for such use, I propose to make the portion 23V of the handle with a transverse line of weakness 42 directly above the upper flange 41, so that when the grenade is to be usedina trench mortar, the handle may bev broken along this line of weakness so that it can be 'swung' inwardly-above fthe flangel 41' thereby permitting'the device to be loadedv into the mortar. The bore of the-mortar-- will serve" to holdV the handle inpos'ition` until thegrenade is thrownfroni the mortar.
