To remove the breech pin model of 1866: After removing the side plates and links, the spring-catch must be next taken out, which is done by moving the breech-pin back so that the pin that holds the spring catch will be in a line with a corresponding hole through the frame; then with a small steel wire punch out the pin, then move the breech-pin forward and take out the spring catch; the piston can then be unscrewed with pliers or hand vise, first setting the hammer at full cock, or taking it out. In models of 1873 and 1876: After removing the side plates and links, take out the link pin and retractor; the piston can then be pulled out with the fingers, first removing the hammer or setting it at full cock. Should the main spring require strengthening it can be done by turning up the strain-screw, which will be found directly under it, on the under side of the frame. _Remington’s Rifle Cane.—(Made by E. Remington & Sons Ilion, N. Y.)_—Directions for using: To load, unscrew the handle or breech from the body of the cane; insert the cartridge and replace the handle, drawing back the handle will cock the piece ready for firing, when pressing on the trigger-knob underneath will discharge it. Do not press on the trigger-knob when the piece is being cocked. The lock-case or breech may be closed by a slight pressure upon the spring sight. For hunting or target practice, remove the tip or ferule at the muzzle. If it is required to use the arm suddenly, as for self-defense, it is not necessary to remove the tip. To remove the lock-case, remove the ferule under the handle by driving it down, take out the pin under the ferule, draw out the handle, draw the cane to full cock and press down and back the trigger, unscrew the lock from the barrel and push the cock out at the top end of the case. In replacing the lock be careful to get the slot on a line with the guide inside of the case, and press down the sight spring. _Billings’ Breech Loading Shot Gun.—(Made by Billings & Spencer, Hartford, Conn.)_—This arm is provided with a backward and upward moving breech block in the rear of the cartridge, the breech block turning backward upon the hinge, which is a more natural motion than a forward turn. To open the breech for loading, half cock the piece; draw the locking bolt with small handle on right side, and pull towards you; this retracts the firing pin, also extracts the shell automatically at the same time.
