摘要： A draft gear assembly includes housing and an elastomeric spring stack disposed therewithin and including a plurality of compressible elastomeric springs disposed in series with each other. Each compressible elastomeric spring includes a compressible elastomeric pad, a rigid member positioned in direct contact with one end surface of the compressible elastomeric pad, a central aperture through a thickness of the rigid member, an abutment upstanding axially on the end surface of the compressible elastomeric pad, the abutment having a peripheral surface thereof sized to be received within the central aperture formed through the thickness of the rigid member, and an annular lip disposed on a distal end of the axial abutment in a plane being substantially transverse to the central axis, whereby an annular thickness portion of the rigid member is caged between the end surface of the compressible elastomeric pad and an inner surface of the annular lip.

摘要： A shoulder-fired firearm primary and secondary recoil attenuator mounts on the butt of a shoulder-fired firearm to absorb both the primary and secondary recoil impulses with distinct spring rates and viscoelastic hysteresis. The attenuator may include a mount plate attachable to a butt of a shoulder-fired firearm. A shoulder plate may be disposed in a spaced-apart, parallel relationship with the mount plate. At least one damper may be disposed between the mount plate and the shoulder plate. The at least one damper may include a viscoelastic copolymer elastomer material having a hollow body elastomer construction. The viscoelastic copolymer elastomer material may be shape-engineered to exhibit time-dependent strain. Accordingly, the at least one damper may have distinct spring rates in response to a primary recoil impulse caused by acceleration of a bullet traveling through a firearm barrel and a secondary recoil impulse caused by ejection of the gases exiting the firearm barrel.
