Abstract: A foraminated, laminated ballistic grill for armored vehicles has a hard outer layer of ballistic material with a plurality of projections having angled faces on the exposed surface. A ductile inner layer adapted to trap and contain ballistic fragments and projectiles backs the outer ballistic surface. A multiplicity of shaped foramina pass through the inner and outer layers to allow air flow into the grill, the foramina have a curved channel, wherein at least a portion of the channel is offset from the longitudinal axis of the inlet so a particle entering the inlet is forced to travel a curved tortuous path.

Abstract: An improved blast shield for use on a wheeled military vehicle. The blast shield has at least a portion responsive to a blast under the vehicle that reacts in response to the blast to block the door of the passenger compartment whereby the occupants of the compartment are protected from ejection from the vehicle for the duration of the blast effect.

Abstract: A locking mechanism limits the motion of a vehicle cab that swings down on the vehicle chassis to rest on a floating bracket, where the floating bracket is supported by shock absorbers mounted to a chassis. The mechanism prevents upward movement of the floating bracket and thereby prevents upward swing of the cab from the chassis. The locking mechanism includes a flat arm fixed to the floating bracket and a fulcrum member fixed to the flat arm. The fulcrum member pivotally mounts a swing arm having a projection at one end. The mechanism is in a locking condition when the projection engages a mounting bracket fixed to the chassis. At different times when the cab swings down to the floating bracket, the cab's alignment with the chassis varies. The locking mechanism has features which allow it to adjust three-dimensionally to variations in this alignment.

Abstract: The present invention is an improved linear action battery clamp usefull for attaching a battery cable to a vehicle's battery terminal. The clamp has a frame member with a fixed jaw and a fixed handle. An actuator rod is mounted in the frame the rod being mounted within first and second bores. The rod has a second jaw mounted on one end moveable towards the fixed jaw of the frame to clamp a battery terminal. A sliding actuator is mounted on the rod being adapted to move the rod linearly the actuator being juxtaposed an actuating arm attached to the frame, the arm having a pair of cam surfaces on one end juxtaposed the actuator for moving the actuator. A brake member acts on the rod the brake normally restricting the rods' linear motion serving to hold the rod in a fixed position. The brake has a release position that allows the rod to be moved in the opposite direction by hand so as to open or disengage the jaw.
