Abstract: Methods and systems are provided for a firearm. The firearm may also include features facilitating efficient assembly/disassembly of the action such as a disassembly latch facilitating rapid and efficient removal of the firearm's action assembly and well as efficient action manufacturing methods.

Abstract: Methods and systems are provided for a firearms suppressor that comprises a self-cleaning function. In one example the firearms suppressor may include a diffusor circumferentially surrounded by a blast chamber and a scrolled sleeve enclosing the inner core of the firearms suppressor. The combination of the said elements may mitigate accumulation of debris within a projectile path of the firearms suppressor and enable extended operation of the firearms suppressor before cleaning is desired.

Abstract: Methods and systems are provided for a firearm. The firearm may include safety features having a trigger block preventing trigger actuation when a lever in the firearm is in a partially cocked position and/or a safety mechanism positioned in front of the trigger.

Abstract: Embodiments related to a self-contained coupler for model railroad rolling stock are provided. In one example, a self-contained coupler comprises a coupler assembly including a knuckle and an uncoupling assembly configured to operate the coupler assembly. The example uncoupling assembly includes a signal input for receiving a signal and a motivator coupled to the coupler assembly via a movable link, the motivator operative to adjust the knuckle from a first position to a second position responsive to the signal. The example uncoupling assembly also includes a housing including the motivator and a rolling stock mounting location for mounting the uncoupling assembly to an item of the model railroad rolling stock.

Abstract: A model railroad coupler for use with model railroad rolling stock includes a coupler head and a coupler knuckle carried pivotally on the coupler head; an elongate coupler shank having one end thereof fixed to the coupler head; a coupler mounting structure carried at the other end of the coupler shank, the shank having a shank longitudinal axis; wherein the coupler head includes a coupler head side flange thereon for preventing over rotation of the coupler knuckle, the coupler head side flange having a flat, inner-facing surface which is parallel to the shank axis; and wherein the coupler mounting structure includes a coupler centering surface adjacent an end thereof, wherein the coupler centering surface has a first, co-linear portion and a second, angled portion wherein a first fulcrum point is located between the first, co-linear portion and the second, angled portion and a second fulcrum point located at an outer margin of the coupler centering surface.

Abstract: A truck for use on a piece of model railroad rolling stock, the truck having axle/wheels sets associated therewith includes two identical truck portions, which, when joined, form a model railroad truck frame, which is held together by mechanical impedance by a frame retainer located in a central mounting structure formed by joining the two truck portions.

Abstract: A truck for use on a model railroad car, in association with plural axle/wheel sets, includes a left truck side frame and a right side frame, each having a bolster receiver therein; an elongate bolster extending between said right frame half and said left frame half, wherein each end of said bolster is received in said bolster receiver of a truck side frame; and a polymer spring member received in each of said bolster receivers between a bottom surface of said bolster receiver and a bottom surface of a bolster end for (1) retaining the bolster in the bolster receiver, and (2) allowing limited torsion of said left truck frame and said right truck frame relative to one another and to said bolster.

Abstract: A magnetic core actuator includes a housing, formed of a non-magnetic material, having a generally tubular shape; a coil, which includes a left hand portion and a right hand portion, wherein each portion, when energized, generates a magnetic field wherein the magnetic fields generated by the left hand portion and the right hand portion have like fields facing one another; and a pair of magnetic armatures, including a left hand armature and a right hand armature, retained in said housing, wherein said magnetic armatures are mounted with like poles facing one another within said housing, said magnetic armatures being driven to opposite ends of said housing by their magnetic fields, and said armatures being shifted towards the center of said housing when power is applied to said coil. As used in a model railroad car, a linkage mechanism extends between the magnetic core actuator and a coupler on a model rail road car for shifting the coupler between its coupled condition and its uncoupled condition.

Abstract: An improved model railroad coupler incorporates a coupler shank, having a joining element at one end thereof and a coupler head at the other end thereof. A coupler-knuckle receiver is located within the coupler head and receives a coupler knuckle. The knuckle is provided with limited, rotational movement within the coupler head, through a predefined arc. The coupler head has a first knuckle stop located thereon which limits rotational movement of the coupler knuckle relative to the coupler head in a first direction of rotation. A second knuckle stop is located on one side of the coupler head adjacent to the shank. A knuckle limiter is located on the coupler knuckle. The second knuckle stop and the knuckle limiter are constructed and arranged to abut one another when the coupler knuckle is shifted to an open position, thereby stopping rotation of the coupler knuckle relative to the coupler head.

Abstract: A model railroad remote uncoupler mechanism is intended for use with a signal-receiving mechanism and a self-centering coupler. A coupler is mounted on a unit of model railroad rolling stock, and is shiftable between a coupled condition, wherein the coupler engages a coupler on another unit of rolling stock, in an uncoupled condition. The remote uncoupler mechanism includes an electromotive actuator, which is activated by the signal-receiving mechanism, and a connector, which extends between the electromotive actuator and the coupler for shifting the coupler between its coupler position and its uncoupled condition. A power supply is provided for the remote uncoupler mechanism, which power supply may be carried on-board the rolling stock, or may include a pick-up mechanism for collecting power from the energized rails of the model railroad layout.
