SHELL. APPLICATION FILED AUG. zu, 1907. 'j

and embedded in the paper base or, in. the

particular form of shell shown, in what is Called'wound wad 3 v By this construction it will be `seen that `5 the primer cup rests on the bottom ornearly. fso of the battery cup with which it is forced into contact as described, and the anvil 6"" being firmly and centrally set as contradisf tnguished frointhe ordinary form of sepa- 10 rate anvil, the tiring of the primer is ren# -dered more certain and effective. It will v also be seen that this construction is much more economical bothY inthe original cost of producing the parts,` since one less part is re quired tlianforinerly, and also the cost of `assembling and handling the parts is less than, the old form of construction of battery cup and separate' anvil. The double vent in the bottom of the battery cup is also an im provemcut over the central vent necessitated by the ordinary .form of battery Vprimer in which it was necessary to provide-means for securing the base of theanvil at the bottom of thc battery cup.

but

That I claim is: i. 'fin a shell, a battery primer embodying a primer-cup and a battery cup, the said bat tery cup having bottom portions thereof -foreed into the interior thereof to constitute an anvil with a'pointed apex vand angulaisupporting'sides.

2. In a shell a battery primer embodying Ia primer cup, and a battery cup', the said battery cup having its bottom forced into the interior thereof to forma pointed an vil with the base thereof extending V,across 4the cup, and having portions of the said i11- wardly projecting bottom cut away to pro- ;vide double vents.

3. In' a shell a'battery primer embodying battery cup having its bottom` forced into the interior of the cup to form a pointed anvil,"and having a portion of the said bottom cut away to provide a vent, the base of the anvil extending transversely of the cup. v 4f. In a shell a battery primer embodying api-imei' cup, and a battery cup adapted toA receive the primer cup, and having its bottorn forced into the interior thereof to pro,- vide an anvil extending across the cup and adapted to enter theinterior' ofthe primer cu Ina-shell' avbattery primer embodying a primer cupland a battery cup',4 and an anvil formeduntegrally'therewith and extending across the bottom of the cup to form a convenientopeningin the bottom on each side'of the anvil. y

In order that the invention might be fully understood, the details of. an embodimentV thereof have been thus specifically described;`

a. primer cup, and 'a battery cup, the saidy 'ing the perforated ,y l

having its' other ,end crimped or upset into. gas .tight ,connection with'the base of the Arii der embodying seance of saidfbattery cup, andan inciosing hood,

the said hood passing through the reinforcing wound wad and havinor its forward edge rmly upset into said wat'.

8. In a shotgun shell including a paper tube and a cup 4of ductile material, :ininterior Wad or reinforcement having an opening therethrough, in. combination with a battery cup primer comprising a primer' cup and a battery cup, there being an anvil formed integrally with said battery cup, and an imperforate hood inclosing the said battery cup primer at one end, and having its other end crimped into gas tight conocen 'tion with the said interior wad or reinforcement.

9. In a central tire shotgun shell. .for nitro powders, the combination with a paper tube Joined to a base of ductile material perfo rated at its center, having the edge sur lrounding said perforation depressed, inA
