Abstract
Abstract An electrical current generator for projectiles which is operated by impact. A cap is mounted so as to transfer direct forces to a striker which in turn compresses a substance which responds by generating current. To accommodate indirect or angular forces, the cap is mounted for translatory displacement which by a camlike action is converted into axial displacement of the striker to compress said substance.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
An impact-operated electrical current generator for a projectile comprising impact receiving means, support means supporting the impact receiving means for displacement, upon impact, axially or transversely relative to the projectile, a compression responsive substance adapted to generate electrical current, and striker means cooperating with the impact receiving means upon axial or transverse displacement of the latter to compress said substance to generate said current, said striker means and impact receiving means including mutually cooperating surfaces such that transverse displacement of said impact receiving means is converted into a substantially axial displacement of said striker means.
Claim 2
Dependent Claim
95 words
An impact-operated electrical current generator for a projectile comprising impact receiving means, support means supporting the impact receiving means for displacement, upon impact, axially or transversely relative to the projectile, a compression responsive substance adapted to generate electrical current, and striker means cooperating with the impact receiving means upon axial or transverse displacement of the latter to compress said substance to generate said current, said striker means and impact receiving means including mutually cooperating surfaces such that transverse displacement of said impact receiving means is converted into a substantially axial displacement of said striker means.
Claim 3
Dependent Claim
22 words
A generator as claimed in claim 1 comprising means to support the striker in spaced relation to said substance prior to impact.
Claim 4
Dependent Claim
26 words
A generator as claimed in claim 1, wherein the impact receiving means and striker means having cooperating camlike surfaces to convert transverse displacement of the latter.
Claim 5
Dependent Claim
22 words
A generator as claimed in claim 1, wherein said support means is a shearable beltlike member integral with said impact receiving means.
Claim 6
Dependent Claim
18 words
A generator as claimed in claim 4, wherein the means to support the striker is a shearable bolster.
Claim 7
Dependent Claim
27 words
A generator as claimed in claim 1 further comprising an anvil below said substance, a cap atop said substance, and electrical connections to said anvil and cap.
Claim 8
Dependent Claim
23 words
A generator as claimed in claim 1, wherein the impact receiving means and striker means have surfaces which are respectively concave and convex.
Claim 9
Dependent Claim
12 words
A generator as claimed in claim 7, wherein the surfaces are conical.
Claim 10
Dependent Claim
19 words
A generator as claimed in claim 1 comprising a bracket block supporting saiD substance and striker on said projectile.
Claim 11
Dependent Claim
17 words
A generator as claimed in claim 1, wherein said impact receiving means is supported on the projectile.
