专利汇可以提供Expanding bullet专利检索，专利查询，专利分析的服务。并且A bullet including a relatively non-deformable forward nosepiece, a tailpiece constructed of non-deformable material spaced rearwardly of the nosepiece, an intermediate piece of deformable material (preferably more dense) disposed between the nose and tailpieces, and a cylindrical jacket telescoped snugly about the intermediate piece and at least the rear and front end portions of the nose and tailpieces. The nose and tailpieces are constructed of a material such as steel, the intermediate piece is constructed of a material such as lead and the jacket is constructed of a material such as copper.，下面是Expanding bullet专利的具体信息内容。
2. The combination of claim 1 wherein said intermediate section is constructed primarily of lead.
3. The combination of claim 1 wherein said sleeve is constructed primarily of copper.
4. The combination of claim 1 wherein the rear and front end portions of said nose and tail pieces, respectively are concave and the front and rear end portions of said intermediate piece are convexed.
5. The combination of claim 1 wherein said sleeve includes a rear end face wall against whose forward face the rear end of said tail piece is abutted.
6. The combination of claim 1 wherein the rear end portion of said nose piece includes a circumferentially extending and radially outwardly opening groove into which the forward circumferential edge portions of said sleeve are laterally inwardly directed.
7. The combination of claim 1 wherein the rear end portion of said nose piece includes a circumferentially extending and radially outwardly opening groove into which the forward circumferential edge portions of said sleeve are laterally inwardly directed, said sleeve including a rear end walL against whose forward face the rear end face of said tail piece is abutted.
8. The combination of claim 1 wherein said tail piece is constructed of steel.
9. The combination of claim 1 wherein said tail piece has a rearwardly opening blind bore formed therein, and a plug of dense material, such as lead, disposed in said blind bore.
10. An elongated bullet including three major body pieces each including front and rear end portions, spaced longitudinally of the bullet in end-to-end aligned relation, said body pieces including a nose piece, an intermediate piece disposed behind the hose piece and constructed of a soft deformable material and a tail piece disposed behind the intermediate piece, said nose and tail pieces each being constructed of a material less deformable than said intermediate piece, connecting sleeve means including front and rear end portions and an intermediate portion, the intermediate portion of said sleeve means being snugly telescoped about said intermediate piece, the front end portion of said sleeve means being telescoped over and secured to at least the rear end portion of said nose piece, the rear end portion of said sleeve means being stationarily supported from at least the forward end portion of said tail piece, and said sleeve means being less deformable than the material of which said intermediate piece is constructed and yet reasonably deformable and rupturable, whereby high speed impact of said nose piece with a target offering at least minimal resistance will decelerate said nose piece and the momentum of said tail will cause the intermediate piece to be axially compressed, and thus radially expanded, between said tail and nose pieces to expand and rupture the portions of said sleeve means disposed about said intermediate piece.
11. In combination of claim 10 wherein said tail piece and sleeve means are integrally formed from the same material and said sleeve means defines a forward extension of the forward outer peripheral portion of the tail piece.
12. An elongated bullet including three major body sections, each including front and rear end portions, spaced longitudinally of the bullet in end-to-end aligned relation, said sections including reasonably non-deformable front and rear sections and an intermediate section more readily deformable than the front and rear sections and disposed between the latter, connecting sleeve means including front and rear end portions and an intermediate portion, said intermediate portion of said sleeve means being snugly telescoped about said intermediate section and the front end portion of said sleeve means being telescoped over and secured to at least the rear end portion of said front section, the rear end portion of said sleeve means being stationarily supported from at least the forward end portion of the rear section, said sleeve means being constructed of a material less deformable than said intermediate section and yet a material which is reasonably deformable and rupturable, whereby high speed impact of the front section with a target offering at least minimal resistance will decelerate said front section and the momentum of the rear section will cause the intermediate section to be axially compressed, and thus radially expanded, between the rear section and the front section to expand and rupture the portions of said sleeve means disposed about said intermediate section.
