3. Remove the cascable-plate.
4. Take out the steady-pin; then turn the crank downwards and remove the crank shaft in that position.
5. Remove the rear sight, and take out the large gear-wheel.
6. Take out the rear plug in the diaphragm, and then gently revolve the gun until a lock presents itself on a line with the hole in the diaphragm, through which one lock after another is taken out.
7. Take out the breech-casing screws, and remove the casing by drawing it off to the rear. Care is taken in this operation to have the lock-cylinder and gun supported, so as to keep the axis of the main shaft parallel to the top of the frame. This is necessary to prevent the rear end of the gun from dropping when the casing is removed.
8. Remove the pin from the large nut on the main shaft in rear of the locks, and take this nut off by turning it to the right; then remove the lock-cylinder and carrier from the main shaft.
The spiral cam need not be taken out of the casing in order to take the gun apart.
TO ASSEMBLE THE GUN.
1. Put the main shaft in its place through the plates which hold the barrels, and then put in their proper places the carrier, lock-cylinder, and large rear nut. The latter should be screwed up tight and have the taper-pin put through the nut and shaft.
2. Place the gun within the frame, and let the front end of the main shaft rest in the hole designed for it in the front of the frame. When the gun is in this position, the cocking-ring should be shoved over the lock-cylinder and left for the time loosely around the carrier.
