To take out the hammers, turn _in_ the screws in bottom of the frame until the mainspring will allow the hammer to drop back far enough to allow its being lifted out of the frame. In putting back, be careful to press the projection on the lever on top of the spring that holds it, up to place, before putting the lever-screw in. _Parker Double-barreled Breech-loading Shot Gun. (Made by Parker Brothers, Meriden, Conn.)_—1. Finger piece. 2. Guard. 3. Lifter. 4. Locking bolt screws. 5. Locking bolt. 6. Barrel lug. 7. Trip. 8. Trip spring. 11. Extractor. 13. Joint Roll. The finger piece is solid and a part of lifter. Pressing up the finger piece in front of guard raises the lifter, and its beveled side coming in contact with the locking bolt screw, acts as a wedge to draw the locking bolt from the mortise in the lug, and releases the barrels so that they tilt upward ready to receive the cartridges. When the bolt is back to the position shown in Fig. 2, the small hole which is drilled in the under side of the bolt comes directly over the trip, which, by the assistance of the trip spring, is made to enter the hole in the bolt and thereby hold it in position. For cleaning, it can be very easily removed by taking off the locks and removing the locking bolt screw from the end of the locking bolt, then press down on the trip, which will allow the lifter to be withdrawn without removing either stock, guard or trigger-plate. 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.
