mth@ form kOra disk 21 of Slightly greater' 1 diameter than theY grenade,but substantially 1.0.01A

diagrammatically illustratedY by the'-do'te'rl lines 28. On Aone-face of the Ydiskf27 I provide, in.anysuitable ,wayfas by casting,y L10,5

head 11 (see,F-ig.i1),rand .side {langesSO and i 31 to embrace the. oppositesidesofthe head 110 @weie "Millsgrenade, showing my; adapter applied Y 11 with a frietion fit.` I may also provide another iang'e 32 which rests upon the edges of the Wings 25. On Vthe opposite faceH of the disk I provide a cartridge support or tube 33, perforated at 34 to permit the escape of the gases on the explosion of the cartridge 35. At the discharge end of the .cartridge above the packing `Wad 36 I provide a substantially rigid lplate or Wadt37, adapted 'to impinge against the firing pin 38. This iringpin'may be Vformed inE any suitable Way. I have here shown it as an angled strap struck fromfa plate of sheet metal, `secured at the lower face of `the disk 27 Wit-,lr the pin end of the armA projecting through a h'ole 39 in thelv disk which registers with' the primer 14 in the head of the grenade. The cartridge carrier 33 is of' such' diameterthat itV its Within the conical breech chamber 40 of the gun and'presents'the primer '41 of the'eartridg-e to the firing' v'p'i1f142 of the gun.

The operationv of the adapter isreadily understood.v The vsafetyl cap- 2-1 of the" hand grenade'havingbeen removed (and the cotter pin 26 reinserted, or not, through the holes 24), the nose' 219 of the adapter is caught lfeneath'th'e lip r23` atithe headof .theV grenade, and the adapterfispresjsed down on the head until the latter is firmly seated against the -disk ,27y and the head 11 firmly gripped by the'frictio'n Wingsl 30 and 31 and rests against the stop 32.V `A cartridge 35 having been inserted inthe4 Ycarrier 33, the' grenade isv now droppedidovvn the bore of the gun 23 and eoines'torestin the' breech thereof iii-position foriiring.' When the gun trigger (not shown) is pulled; the firing 'pin 42zis drivenaz'gainstt the primer-41 and the explosivecharge of the cartridge ignited, forcing the Walls off the" shell Vthrough the perforations 24iin the carrier 33. This not only' permits the gases to escape into the breech chamber, but also rivets the[cartridge shell to the carrier, so that Athe cartridge is ejected with the grenade and thec'arrier3'3 fr'om the gun'. At the moment of the explosion of the cartridge charge, the Wad 36. and facing plate 37 are blown against the iring pin 38', driving the latter against"v theV primer'14, the firing" of Which igite'sthe' Vfuse of the grenade.l The pressure ofv thev gases from l the cartridge" charge agalnstv the disk 27 of the adapter drives the latter out ofthe 'gun'with the grenade. During the` grenade, the adaptermay o1 may not' become separated therefrom.

In Figs. 2 and 31' `have shown a modified arrangement of the firing ipinfor the adapter, and have also shown the safet'y cap 21 of thegrenade in position on the grenade head engagedyby the adapter. While the iring pin o f Figs'. 1v and 2 will also vlor'oarch this cap 21 and; strikeithe primer 14 of the gre' nade, I prefer the. construction shownin disk grenade. Y

Vof the adapter 1s now carried by a metal disk F ig. 3 when the cap 21 is retained on the As here shown, the firing ypin 43 44 overlying the wad 36 of the cartridge and passing through the hole 39 in the disk 27.

When the cartridge is fired, the pin 43 penetrates the sheet metal cap 21 and strikes the primer 14, thus igniting the grenade fuse just as in the construction first described. The retention of the eap- 21 renders the use of the adapter still more safe, and the grenade can drop out of the gun Without danger of ignitingI the fuse evenv should lthe lever 1S be struck.

In Fig. 5 'I have shown the grenade grip'. pii'frg'elements oftheadapter struck from `a pilateA ofi sheet metal sp'ot welded to the disk 27.

`Iii-Figs.l (5, 7, 8, and 9 `I have shown the adapter modified to operate the Well known lidills grenade 'in 'common luse inthe British armies.V In thisgrenade, the head of the firing'pin 45 is normally engaged and held against! the action of its firing spring by flanges 46 formed on the endrof the safet;7 lever 47.V `The latter is-stru`ck from sheet n'ietaland is'prov'ided with a trunnion pin 48 which hasbearings in Wing pieces 49 formedat the head ofthe grenade'. A cot te'rpin 50 passing through these wing lpieces, holds the lever 47 in safety position. In this position, the head of 'the firing pin is slightly drawnout of the shell of the grenade, exposing its stem.V Theadapter in the form here shown comprises; as before, the disk 27, upon the grenade face'of which I former secure inany'suitable Wayl a device adapted to engage the' head of this Mills grenade.` As here shown, the engaging means 'Comprisesa pair of legs 51' and 52 freely straddling'the hea-dof the firing pin so as-not to interfere `with the latter, but engagin(r beneath the trunnionpin 4S With a WedgeV action, thus holding the adapter firmly to the head of the grenade. If desired, a tongue 53 may be formed between the legs 51 52, which, in the adjusted po'sition of the adapter, engagesV beneath. the head of the iring'pi1r45 and thus adds'to the seci'irity'ofthe lever'47 inholdingV the firingv pin against' premature release. The legs 51- and 52 are here shown integral With base straps 54;55 secured tothe disk 27 by face of the adapter is provided with a shell= holder' 33 like that first described, and the shell carries at its discharge end, aimetal 57 'with pin. 53, 'whicht in the inserted psiuh of `the Shar' ,passes 'through the vpai-g.
