Abstract

An apparatus for separating a bullet from a cartridge case, or bullet puller or extractor, comprising a frame, a cartridge hold-down fixture mounted on the frame, and a reciprocating chuck made of a pair of sleeves concentrically and slidably disposed one within the other and operated by a lever means. The inner sleeve has a contractible slitted end forming jaw surfaces engageable over the bullet, and the lever means reciprocating the chuck are arranged to first cause the chuck to grip the bullet by applying a holding force to the jaw surfaces at the end of the inner sleeve by reciprocating the inner sleeve relative to the outer sleeve and engaging the inner sleeve tapered end with a tapered inner surface at the end of the outer sleeve. Subsequent motion of the lever means causes the chuck to be pulled away from the cartridge hold-down, thus separating the bullet from the cartridge case.

An apparatus for separating a bullet from a cartridge case, said apparatus comprising a frame, hold-down means mounted on said frame, a reciprocating chuck comprising an inner and an outer sleeve concentrically and slidably disposed one within the other, said inner sleeve having an end forming engageable inner jaw surfaces over said bullet defined by at least a pair of end segments formed by diametrally opposed longitudinal slots extending all the way to the end of said inner sleeve, a tapered peripheral surface formed on said inner sleeve proximate said end and a tapered portion on the inner surface of said outer sleeve for engagement with said tapered peripheral surface for applying said gripping force to said jaw surfaces by urging said opposed segments toward each other, and lever means reciprocating said chuck, said lever means comprising a first lever having a floating fulcrum pivot on said frame and being pivotally attached to said outer sleeve for reciprocating said outer sleeve, a second lever pivotally attached to said inner sleeve and having a floating fulcrum on said first lever for reciprocating said outer sleeves relative to said first sleeve for applying said gripping force to said jaw surfaces and for subsequently reciprocating said inner and outer sleeves in unison away from said cartridge hold-down means.

In an apparatus for pulling a bullet from a cartridge case, said apparatus comprising means for holding said cartridge case, means for gripping said bullet, and power amplifying means for moving said bullet gripping means away from said cartridge case holding means, the improvement for said bullet gripping means comprising a pair of concentric independently reciprocable sleeves, the inner one of said sleeves having a periferally tapered end and the outer one of said sleeves having a correspondingly internally tapered end, said inner sleeve having at least a pair of diametrally opposed segments formed by longitudinal slots extending from the tapered end of said inner sleeve, opposed jaw surfaces formed at the end of said segments, and wherein said power amplifying means are adapted to reciprocate said inner sleeve relative to said outer sleeve for mutually engaging said tapered surfaces for urging said segments toward each other and clamping said jaw surfaces over said bullet and to subsequently reciprocate said inner and outer sleeves in unison for pulling said bullet from said cartridge case, said power amplyfying means comprising a first lever pivotally attached to said outer sleeve for reciprocating said outer sleeve, a second lever pivotally attached to said inner sleeve for reciprocating said inner sleeve, said second lever having a floating fulcrum on said first lever and adapted to first differentially operating said first lever for relatively reciprocating said inner and outer sleeves for applying said gripping force to said jaw surfaces and to subsequently simultaneously operate said first lever for reciprocating said inner and outer sleeves in unison away from said cartridge case holding means.
