To replace the plunger: Withdraw the cone with a common screw-driver, by pressing it against the plunger until the screw-driver enters the slot. After removing the plunger and spring, be careful to replace them with spring at side of plunger.
Remington Double-barreled Breech-loading Shot Gun. (Made by E. Remington & Sons, Ilion, N. Y.)—A, thumb piece; B, lever, engaging locking bolt; C, pivot of lever B; D, locking point; H, joint check; K, pivot pin; L, joint check screw, limiting motion of barrels; M, hammer lifter; N, extractor; O, wire, a shoulder of which rests against P; P, shoulder of dog engaging locking bolt; S, snap action spring.
To take apart: To remove the barrels, take off the tip-stock, full cock both hammers and press the thumb-piece (between the hammers, and used for unlocking the barrels for loading) upward as far as it will go. The barrels can thus be detached.
In Fig. 3, the locking bolt is drawn as far as the shoulder P will allow it to move. This shoulder P is formed on one side of a little dog, in the other side of which is a corresponding shoulder, resting against the wire O. So long as the tip-stock is in place this dog cannot yield or permit the locking-bolt to be drawn far enough to allow the joint-check to come out of the mortise in the frame; but when the tip-stock is removed, the wire O can slip part way out, as in Fig. 4, allowing the shoulder P to move back, so that the locking-bolt can be drawn back clear of the joint-check—thus releasing the barrels.
The Roper Four-shooting Shot-gun and Rifle. (Made by the Billings & Spencer Co., Hartford, Conn.)—A, frame; B, receiver; B¹, hinged lid of receiver; C, hammer; D, plunger; D¹, head of plunger; E, plunger link; F, cartridges; G, carrier in which shells are placed; H, lever to revolve carrier; I, mainspring; J, sear; a, ratchet; b, stirrup; c, link connecting hammer with mainspring; d, pin of lever H; e, pivot of carrier G; f, firing pin; h, elastic tail of lever H.
To take apart: To take the gun apart, turn in the set screw on under side of cylinder forward of the guard plate screw, until it comes to a stop. Then bring the hammer to cock notch and unscrew the cylinder from breech. N. B.—This set screw turns in to take the gun apart, and turns out to fasten the cylinder.
In putting the gun together, screw up the breech until the set screw can be replaced. This screw should be turned sufficiently tight to prevent any looseness of the breech.
To take off the stock and expose the lock, take out the long screw that runs through the small, rear end of receiver on top, and the screw in the guard plate which fastens it to the receiver underneath in front. Then remove the stock, and the working parts are exposed and can be readily cleaned and oiled. The firing pin should be detached occasionally, cleaned and oiled, as its easy working insures certain fire. To do this, take out the small screw in the top of the hammer and remove the piston entirely from the receiver, and the piston and firing pin are readily separated. In replacing the piston, care should be taken to put it in right side up, the retractor spring being at the bottom. Never attempt to take out the screw which fastens the link to the piston, until the firing pin is detached.
Colt’s Revolver For Army Use, Cal. 45.—(Made by the Colt Pat. Fire Arms Co., Hartford, Conn.)—A, barrel; B, Frame; B¹, recoil plate, C, cylinder; DD, firing pan; D¹, center pin bushing; E, guard; F, back strap; G, hammer; H, main spring; I, hammer roll and rivet; J, hammer screw; K, hammer cam; L, hand and hand spring; M, bolt and screw; N, trigger and screw; O, hammer notches. P, firing pin and rivet; Q, ejector rod and spring; Q¹, ejector tube; R, ejector head; S, ejector tube screw; T, short guard screw; U, seat and bolt spring (combined) and screw. V, back strap screw; W, main spring screw; X, front sight; Y, center pin catch screw.
To take apart: To dismount the pistol, half-cock the hammer, loosen the centre pin catch screw; draw out the centre pin, open the gate, and the cylinder can then be withdrawn. To remove the ejector, turn out the ejector tube screw, then push the front end away from the barrel and pull it towards the muzzle. The stock can be removed by turning out the two screws just behind the hammer, and that at the bottom of the strap. Remove the main spring and trigger guard; the parts of the lock can then be readily separated. The cylinder bushing should then be pushed out for cleaning. To remove the gate, turn out a screw in the lower side of the frame (hidden by the trigger guard), then the gate spring and catch can be withdrawn, and the gate can be pushed out.
