To dismount block: Turn keeper screw on end of block and take out stop nut. The firing pin and coil spring will then drop out. To assemble block: Restore firing pin and coil spring. Turn in stop nut, and turn keeper screw to secure it. The firing pin has a rectangular slot near one end. This slot is longer on one side than on the other. The long side should be so placed as to admit end of the tumbler freely. _The Phœnix Breech-Loader.—(Made by Whitney Arms Co., New Haven, Conn.)_—No special directions are necessary for dismounting and assembling the Phœnix system. The breech-block is taken out by loosening the screw that holds the pin, and then taking out the pin. After the breech-block has been removed let the hammer down as far as it will go, which relieves it from the pressure of the main spring, and it can then be easily removed by taking out the screw which holds it. _The Remington Breech-Loading Rifle.—(Made by E. Remington & Sons, Ilion, N. Y.)_—Explanation of parts and technical names: AA. Receiver. B. Breech Piece. C. Hammer. D. Locking Lever. a. Main Spring. bb. Pins. c. Trigger. d. Lever Spring. e. Trigger Spring. f. Firing Pin. g. Extractor. To remove the breech piece and hammer: Loosen the button screw until the button can be removed from the heads of the breech and hammer pins. Cock the hammer, push out the breech pin, take out the breech piece, let down the hammer as far as it will go (which leaves the main spring resting upon a stationary pin, and obviates the necessity of using a main spring vise in readjusting the parts). Remove the hammer pin and take out the hammer. To replace the hammer and breech piece: Lay the arm down on the right side, press upon the trigger at the same time replacing the hammer with the thumb piece forward and downward, until the hole in the hammer and receiver correspond. Replace the hammer pin, cock the hammer, replace the breech piece, insert breech pin in receiver, and by pressing on the pin at the same time pressing down the breech piece and working it back and forth slightly the pin will enter. Adjust the button and tighten the button screw. To take the entire arm apart: Take out the extractor screw, open the breech, remove the extractor, take out the breech piece and hammer, as described. In military arms remove the wiping rod by unscrewing the same, remove the bands, separate the tip stock from the barrel at the muzzle, until it is liberated from the stud upon the under side of the barrel, when it maybe withdrawn from the receiver; take out the tang screw and remove the butt stock. To detach the guard strap: Take out the two side screws which pass through the guard strap, always removing the rear screw first. Unscrew the barrel from the receiver, taking care that the extractor has been removed before unscrewing the barrel.
