Excerpt from Handbook of the 4. 7 Inch Gun Matériel, Model of 1906: With Instructions for Its Care
The breechblock is of the interrupted-screw type, and is provided with four threaded and four slotted sectors. The front end of the axial recess In the block for the hub of the block carrier is closed by a bushing. Three vent holes leading from a cavity in the bushing to the rear through the breechblock permit the escape of gas from a ruptured primer. On a semicircular boss on the rear face of the breechblock are cut gear teeth, in which the gear teeth of the Operat ing lever bevel gear mesh. The upper end of the circular boss on which the gear teeth are cut serves as a stop to limit the rotation of the block in the unlocked position. This upper end of the circular boss comes in contact with a hardened steel stop riveted to the inner face of the block carrier. A radial lug or tooth projects from the inner surface of the breechblock and engages an L-shaped slot cut in the hub of the block carrier, so that when the mechanism is unlocked no relative movement between the breechblock and the block carrier can take place.
