Pistol Percussion Mechanism Horizontal Barrel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing percussion firing mechanisms in pistols often result in cartridge jamming during loading, and maintenance is complicated by the need for specialized tools to access the firing pin, requiring factory-level conditions.
Innovation Solution
The design includes a barrel moving parallel to the slide axis with a cartridge chamber aligned with the magazine, a hammer with a firing pin in the slide's lateral channel, and an automatic safety device, allowing for easy access and maintenance by eliminating cartridge jamming and simplifying the extraction of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the barrel breech moves over the vertical plane downwards during cartridge delivery, then the cartridge can be supplied from the magazine under the barrel axis, but the cartridge jams against the breech end of the barrel
Solution Approach 1:
The patent inverts the traditional barrel movement by making the barrel move horizontally parallel to the slide axis instead of moving the breech vertically downwards. This reversal of the mechanism eliminates the jamming problem while achieving cartridge supply from a magazine positioned under the barrel axis.
Solution Approach 2:
The patent changes the movement parameter of the barrel from vertical downward motion to horizontal motion parallel to the slide axis. This parameter change transforms the cartridge delivery path, allowing the cartridge to be supplied from the magazine under the barrel axis without jamming against the breech end.
2Strength
If the firing pin is held by split tension bushings in the slide, then the firing mechanism is secure, but the firing pin cannot be extracted without special tools during maintenance
Solution Approach 1:
The patent segments the firing pin assembly by providing it with a protrusion that engages with a corresponding recess in the slide. This segmentation allows the firing pin to be securely held during operation while enabling easy extraction during maintenance by simply pressing the firing pin against the trigger, eliminating the need for special tools or factory conditions.
3Volume of moving object
If the magazine is positioned under the barrel axis, then the pistol has compact layout, but the cartridge jams against the breech end during delivery
Solution Approach 1:
The patent inverts the traditional approach by positioning the magazine under the barrel axis (achieving compact layout) but reversing the delivery mechanism so that the barrel moves horizontally parallel to the slide axis instead of moving the breech vertically. This inversion maintains compactness while eliminating jamming.
Solution Approach 2:
The patent changes the delivery parameter from vertical downward motion to horizontal motion, allowing the magazine to be positioned under the barrel axis for compact layout while preventing cartridge jamming through the altered movement path.

AI summary
Invention refers to the armament industry, namely to percussion firing mechanism of the pistol and according to the invention, the barrel is moving inside the frame parallel to the slide axis only, at that the cartridge is located in the magazine in alignment with the barrel, the hammer is performed with firing pin located in the slide lateral channel and has the ledge directed upwards to interact with the hammer spring and the ledge, directed downwards to interact with pistol trigger mechanism, at the rear part of the slide, under the hammer the port is performed, which contains the hammer spring module, located in case, which is fixed at the front part of the slide port by means of catches and by means of the cross pin at the rear part and contains the tube-form extractor with collar for the interaction with hammer ledge, at that the front end of the guide is inserted in extractor lateral hole, but its rear end intrudes in the hole, performed at the guiding socket base, the hammer spring, located inside the guiding socket between the guiding socket base and extractor collar, grips the guide and extractor and the ends of the guide are inserted into the module case walls holes, therewith the firing mechanism contains the automatic safety device, ledge of which, driven by the safety device spring intrudes into the hammer notch, providing its lengthwise displacement inability. The invention allows improving the pistol operation durability due to the cartridge jamming against the barrel breech face possibility elimination, and to ensure maintenance, disassembly, cleaning ease due to the firing mechanism components, located in the quick-release module of the slide.
