Abstract
The present disclosure relates to an Improved Ballistic Chain Cutting Device. In general, the device positions a target link from a multi-link chain in the proper placement for a single shot from a firearm to cut or sever the target link. Embodiments of the improved device include a specially designed slot with stepped sidewalls creating a varying width to tightly receive the target link, a curved adjacent link engagement region to better accommodate the semicircular end of a link adjacent the target link, and a curved target link engagement region to better secure the target link within the device.
Claims24
A chain cutting apparatus that aligns a target link and an adjacent link of a multi-link chain for ballistic opening of the target link, comprising:
- a base member having a proximal end, a distal end, and a projectile aperture extending between said proximal end and said distal end, said projectile aperture having a center axis;
- at least one wall extending from the proximal end of the base member, said at least one wall having an interior surface at least partially defining a substantially cylindrical volume, said substantially cylindrical volume having a center axis coaxial with the center axis of the projectile aperture;
- a first target link pin extending from the distal end, said first target link pin having a first pin adjacent link engagement region and a first pin target link alignment region;
- a second target link pin extending from the distal end, said second target link pin having a second pin adjacent link engagement region and a second pin target link alignment region;
- a slot between the first target link pin and the second target link pin, said slot having a first sidewall at least partially defined by the first pin target link alignment region and a second sidewall at least partially defined by the second pin target link alignment region, said sidewalls defining a width of said slot, said sidewalls having at least one pair of corresponding steps where said width increases, said at least one pair of corresponding steps being oriented substantially orthogonal to the center axis of the projectile aperture;
- an adjacent link pin extending from the distal end, said adjacent link pin having a target link engagement surface.
A chain cutting apparatus that aligns a target link and an adjacent link of a multi-link chain for ballistic opening of the target link, comprising:
- a base member having a proximal end, a distal end with a planar surface, and a projectile aperture extending between said proximal end and said distal end, said projectile aperture having a center axis;
- at least one wall extending from the proximal end of the base member, said at least one wall having an interior surface at least partially defining a substantially cylindrical volume, said substantially cylindrical volume having a center axis coaxial with the center axis of the projectile aperture;
- a first target link pin extending from the distal end, said first target link pin having a first pin adjacent link engagement region and a first pin target link alignment region;
- a second target link pin extending from the distal end, said second target link pin having a second pin adjacent link engagement region and a second pin target link alignment region;
- a slot between the first target link pin and the second target link pin, said slot having a first sidewall at least partially defined by the first pin target link alignment region and a second sidewall at least partially defined by the second pin target link alignment region, said sidewalls defining a width of said slot and extending through the planar surface of the distal end into the base member;
- and
- an adjacent link pin extending from the distal end, said adjacent link pin having a target link engagement surface and an angled back surface opposite the target link engagement surface.
A chain cutting apparatus that aligns a target link and an adjacent link of a multi-link chain for ballistic opening of the target link, comprising:
- a base member having a proximal end, a distal end, and a projectile aperture extending between said proximal end and said distal end, said projectile aperture having a center axis;
- at least one wall extending from the proximal end of the base member, said at least one wall having an interior surface at least partially defining a substantially cylindrical volume, said substantially cylindrical volume having a center axis coaxial with the center axis of the projectile aperture;
- a first target link pin extending from the distal end, said first target link pin having a first pin adjacent link engagement region and a first pin target link alignment region;
- a second target link pin extending from the distal end, said second target link pin having a second pin adjacent link engagement region and a second pin target link alignment region;
- a slot between the first target link pin and the second target link pin, said slot being at least partially defined by the first pin target link alignment region and the second pin target link alignment region;
- an adjacent link pin extending from the distal end, said adjacent link pin having a target link engagement surface and an angled back surface opposite the target link engagement surface.
