“W. Tranter’s patents for a double trigger, a safety-hammer spring, an elongated socket for the chamber, a loading lever, and a lubricating bullet for revolving arms, increase the value and efficiency of these arms as defensive weapons. [Illustration: Half size of the medium 54 gauge double-trigger Revolver.] “By means of the patent double-trigger the pistol can be held more firmly in the hand while being fired, and only one hand is required to raise the hammer and fire the pistol. A perfectly accurate and quicker aim can be taken, and the pistol discharged at the instant desired; the hammer can be raised again without lowering or removing the pistol from the object till the whole of the chambers are fired off. The chamber is held firmly opposite the front barrel before the hammer begins to fall, and also at the moment it is discharged; the chamber cannot be turned away from the front barrel by the hammer at the moment it is discharged. In cases of emergency the pistol can be fired with the greatest rapidity by pulling both triggers together. The exploded caps do not get into the works and render the pistol useless till removed. But little practice is required to enable a person to shoot with accuracy. “The patent safety hammer spring always acts with the hammer and trigger; should anything accidentally lift the hammer, the safety-spring instantly falls under it and prevents it falling upon the cap, thereby preventing an accidental discharge. The safety-spring also facilitates the loading, by allowing the hammer to rest upon it while the chambers are being charged, and at the same time acting as a safety-spring during the operation of loading. The pistol can be carried with perfect safety when loaded, either in the pocket or holster, by allowing the hammer to rest upon the safety-spring. “By means of the patent elongating socket, the chamber can be properly and readily adjusted to the frame of the pistol; and as the chamber with use becomes too free, and the strength of the shooting depreciated, the elongating socket enables it to be readjusted as perfectly as when first made--an important consideration with these arms. “The patent loading lever enables the pistol to be loaded with greater facility, and fits the lubricating bullet to the chamber so exactly that the powder cannot fail to bend up the flange of the bullet and distribute the lubrication all over the inner surface of the chamber and barrel; it also fixes the bullet so firmly in its place in the chamber that it does not fall out with being carried in the pocket or holster, neither does it project forward with the firing of the pistol.
