Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
65 words
A bullet decelerator comprising: a housing, a lining of pliable material within said housing, a plurality of bullet resisting elements within said lining, resilient elements within said lining, whereby said bullet resisting elements completely decelerate a bullet entering said housing, and said resilient elements retain fragments produced by the passage of said bullet through said resisting elements and serve to protect said housing from distortion.
Claim 2
Dependent Claim
65 words
A bullet decelerator comprising: a housing, a lining of pliable material within said housing, a plurality of bullet resisting elements within said lining, resilient elements within said lining, whereby said bullet resisting elements completely decelerate a bullet entering said housing, and said resilient elements retain fragments produced by the passage of said bullet through said resisting elements and serve to protect said housing from distortion.
Claim 3
Dependent Claim
37 words
A bullet decelerator according to claim 1 wherein said resilient elements are arranged so that a resilient element is penetrated by the bullet before a resistant element and said resilient elements are alternated with said resisting elements.
Claim 4
Dependent Claim
20 words
A bullet decelerator according to claim 2 wherein the resilient elements are spaced from adjacent resisting elements by ring washers.
Claim 5
Dependent Claim
18 words
A bullet decelerator according to claim 2 wherein said resilient elements are provided with an integral spacing ring.
Claim 6
Dependent Claim
20 words
A bullet decelerator according to claim 3 wherein the centers of the spacing ring washers are filled with resilient material.
Claim 7
Dependent Claim
36 words
A bullet decelerator according to claim 2 wherein said housing has an interior portion, said interior portion being more deformable than the remainder of said housing, said interior portion serving as the lining of pliable material.
Claim 8
Dependent Claim
23 words
A bullet decelerator according to claim 9 wherein said deformable interior portion is provided by selective annealing of the interior of said housing.
Claim 9
Dependent Claim
72 words
A bullet decelerator for use in propelling a projectile comprising, a housing, a plurality of bullet resistant elements within said housing, spacing means to separate said resistant means, the over-all size of said resistant means being smaller than the adjoining inside dimensions of said housing, said housing being provided with a lining of pliable material, whereby said resistant means may expand under impact of the bullet without producing deformation of the housing.
Claim 10
Dependent Claim
72 words
A bullet decelerator for use in propelling a projectile comprising, a housing, a plurality of bullet resistant elements within said housing, spacing means to separate said resistant means, the over-all size of said resistant means being smaller than the adjoining inside dimensions of said housing, said housing being provided with a lining of pliable material, whereby said resistant means may expand under impact of the bullet without producing deformation of the housing.
Claim 11
Dependent Claim
31 words
A bullet decelerator according to claim 8 wherein resilient elements are disposed within said housing, said resilient elements retaining fragments produced by the passage of a bullet through said resistant means.
