Rearward Sliding Breech Bolt Patents (Class 42/69.02)
  • Patent number: 9970723
    Abstract: A trigger mechanism for a firearm includes a sear which interacts with a trigger. The sear and trigger are held in contact by a sear block. The sear block has dogs which engage respective locking surfaces on the sear and trigger. Pivoting motion of the sear block disengages the dogs from the trigger and sear and allows the trigger to pivot and release the sear to discharge the firearm. When the dogs are engaged with the sear and trigger the resistance to inadvertent discharge due to inertial loads imposed on the mechanism when the firearm is dropped is increased.

  • Patent number: 9671186
    Abstract: A trigger mechanism that gives a shooter a durable, adjustable, soft and gentle pull. In this design, the sear block remains, but the trigger mechanism is replaced with a new, softer action mechanism. This mechanism uses a tripper that attaches to a trip. The trip is a formed body that has a lower frame and a top bearing that sits against the bottom of the seer. When the trigger is pulled, it rotates the tripper forward, which causes the trip to rotate backwards. The backward movement of the trip causes the top bearing to roll off the bottom of the seer, causing the gun to fire. The rotation of the trip is smooth compared to the snapping action of the seer in the prior art designs. This smooth movement does not jar the action, making for a better shot.

  • Patent number: 9631886
    Abstract: A trigger assembly has a sear with a stop surface engageable with a reciprocating component for holding the reciprocating component in a cocked configuration. A trigger is movable into and out of engagement with the sear to hold and release the reciprocating component. A drop pendulum has a trigger cam engageable with the trigger. A spring acts between the trigger and the drop pendulum to bias the trigger cam into engagement with the trigger. The drop pendulum also has a head cam follower engageable with the reciprocating component. Motion of the reciprocating component acting through the head cam follower and the trigger cam forces the trigger to return to a configuration of engagement between the trigger and the sear. Use of the drop pendulum improves the stability of trigger mechanisms and effectively inhibits accidental discharge of firearms when subjected to inertial forces which occur when the firearm is dropped.

  • Patent number: 9046313
    Abstract: Applicants have disclosed an adjustable modular trigger assembly, and a related method, to avoid an unexpected firing of a long gun after an unintentional trigger pull. Applicants' preferred assembly comprises: a modular trigger housing, containing every trigger component, designed to be removably mounted within a lower firearm receiver; a trigger pull adjustment screw in a housing wall; and a sear force adjustment screw in another housing wall. During an intentional trigger pull, the shooter's finger pushes against a secondary trigger until it nestles within a slot of a non-coaxial primary trigger. Continued pulling on both triggers causes a sear to fall off a hammer notch and the firearm to discharge. In an unintentional trigger pull or jostling of the primary trigger, hooked protrusions (within the housing) of the second trigger and hammer engage to block the hammer from fully rotating, thereby avoiding discharge of the firearm.

  • Patent number: 8677665
    Abstract: A trigger may be pivotally connected to a frame at or near the top of the trigger. A sear transfer bar may be further provided and is pivotally connected to the frame. The pivot in the trigger is higher within the frame as compared to the pivot of the sear transfer bar. Two balls can be between the trigger and the sear transfer bar. The top of the sear transfer bar has a sear contact. Pulling the trigger in a first direction causes the trigger to rotate in a first direction. The sear transfer bar rotates under force of the trigger. The sear transfer bar and the trigger may rotate in opposite directions. The sear will drop when the sear contact of the transfer bar ceases engagement with the sear, causing the firearm to fire. The trigger assembly has a control arm extending beyond the trigger assembly frame.
