Abstract
Official abstract text for this publication.
A sear mechanism for a firearm includes a trigger element having one or more contact surfaces on which one or more movable or pivotable components of the sear mechanism selectively contacts or slides. In some embodiments, the trigger element is made by producing an intermediate workpiece of the trigger element by a manufacturing process, and electric discharge machining the intermediate workpiece of the trigger element to provide the contact surfaces.
First claim
Opening claim text (preview).
1 - 15 . (canceled) 16 . A trigger element for production of a sear mechanism for a firearm, the trigger element produced by a process comprising: producing an intermediate workpiece of the trigger element by a manufacturing process; and electric discharge machining the intermediate workpiece of the trigger element to provide at least one contact surface onto which at least one pivotable element of the sear mechanism selectively contacts. 17 . The trigger element of claim 16 , wherein the intermediate workpiece including a trigger sear configured to selectively engage a hammer sear of a hammer element, the hammer element for production of the sear mechanism, and wherein electric discharge machining the intermediate workpiece of the trigger element includes electric discharge machining the trigger sear to provide a sear contact surface onto which the hammer sear slides. 18 . The trigger element of claim 17 , wherein electric discharge machining the trigger sear comprises: engaging a metal wire through a sear processing aperture of the intermediate workpiece; and moving the intermediate workpiece or the wire relative to each other to form the sear contact surface. 19 . The trigger element of claim 16 , wherein electric discharge machining the intermediate workpiece of the trigger element includes electric discharge machining a hammer pad to provide a hammer contact surface onto which a hammer tail of the hammer element slides, the hammer pad configured to selectively engage the hammer tail of the hammer element. 20 . The trigger element of claim 16 , wherein electric discharge machining the intermediate workpiece of the trigger element includes electric discharge machining a disconnector pad to provide a disconnector contact surface to which a disconnector element of the sear mechanism contacts, the disconnector pad configured to selectively engage the disconnector element.
