Abstract
This invention improves on firearm frame manufacture by modularizing the frame into a frame and modular core block assembly providing ease of manufacture and servicing.
Description
- 1. Field of Invention
- This invention relates to firearms and the use of a modular core block construction.
- 2. Description of the Related Art
- Firearms with break-open frames have traditionally been manufactured as a single piece with complex machining of firing pin holes, relief's for springs and action components necessary to hollow out a solid block or forging. The numerous setups to complete a frame reduce the weight from a 3 to 5 pound piece of steel down to less than 2 pounds. If any one operation is out of tolerance then the frame is ruined.
- This invention improves on firearm frame manufacture and prior art by modularizing the frame into a frame and a rebuild-able modular core block assembly. The modular core block assembly contains the core block face, firing pins, firing pin springs and other components. As such the modular core block can be manufactured separately from the frame using different materials that optimize each part's strength and performance. It's size and shape simplifies the manufacturing process.
- This invention improves on firearm frame manufacture by modularizing the frame into a frame and modular core block assembly. The modular core block assembly contains the firing pins, firing pin springs and other components. It is manufactured separately from the frame and due to it's size and shape can be more easily made. Once assembled it slides into the frame and is designed to withstand all pressures produced from firing the gun. If parts break within the module or wear out, the parts that fail can be repaired without replacing the frame.

- This invention improves on firearm frame manufacture by modularizing the frame into a frame and modular core block assembly. The modular core block assembly contains the firing pins, firing pin springs and other components. It is manufactured separately from the frame and due to it's size and shape can be more easily made.

FIG. 1 is a perspective view of the frame and modular core block construction. Theframe 1 is illustrated with the modularcore block assembly 2 in place in the firearm. -
FIG. 2 is an exploded view of the frame and modular core block construction. Theframe 1 is illustrated with the modularcore block assembly 2 removed from the firearm. The Frame relief for modularcore block assembly 1A is illustrated in this view and is a negative form of the modular core block assembly shape so that the assembly can slide into theframe 1 and fasten in place. The modularcore block face 2B clamps onto theframe 1 and keeps it securely in place in the frame by sandwiching the frame relief for modularcore block assembly 1A between the modularcore block face 2B and the modularcore block buttress 2H. -
FIG. 3 is a cross sectional view of the modular core block assembly that illustrates how key parts of the assembly are positioned for use. The modularcore block assembly 2 is comprised of:modular core block 2A, modularcore block face 2B that has holes for the firing pins to go through to ignite the primer in the shell when firing the gun, the firingpin transfer plate 2C and thetransfer pin 2F transfer the energy form the gun's hammers when firing the gun to ignite the shell's primers thereby firing the shell, the firing pin transferplate return spring 2D and firing pintransfer plate pin 2E allow the firingpin transfer plate 2C to swing forward to ignite the shell and retract under spring force after firing the shell, and the modular coreblock assembly screws 2G. The lever pocket 2I that holds the firearm's lever that allows on to open and lock close the firearm when unloading, loading and firing the gun. -
FIG. 4 is an exploded view of the modular core block assembly provides a more detailed view of each part of the assembly.Components 2A through 2I are the same as inFIG. 3 with a more detailed view of the firing pin transferplate return spring 2D showing the torsion spring that brings the firing pintransfer plate pin 2C back to a neutral position after the gun is fired. The nature of the exploded view of the modular core block assembly provides a view of the modular core block transfer plate pin hole 2J that holds the firing pintransfer plate pin 2E that the firingpin transfer plate 2C rotates on. When servicing the gun, the firing pintransfer plate pin 2E is removed by using a drift punch inserted through the modular core block drift hole 2K to drive the pin out. The modular core block relief for transfer plates & transfer pins 2L that house the firingpin transfer plate 2C and transferpin 2F. The modularcore block buttress 2H is shown clearly in this figure and was explained in theFIG. 2 narrative. - In summary the advantages of the modular core block construction are: ease of manufacture, easier servicing and repair or replacement of parts for a longer life firearm.
