My Invention is also applicable to revolving pistols; Figure 9, shows a plan, and Figure 10, a side view of a revolving pistol having my Invention applied thereto. Figue 11, shows a section, Figure 12, shows a side and two end views of the barrels; Figure 13, shews another section; Figure 14, is part of an end view, Figure If), shews separate views of the hammer ; and Figure 16, shows separate views of the trigger and working parts ; in each of which Figures the same letters indicate similar parts, c, is the hammer formed on the spring which is fastened to the stock at c2; and the hammer c, is lifted by the pendant finger rt, which is connected by a pin joint to the under side of the hammer c, and is pressed on by the spring a\ as shown, so that it has at all times a tendency to stand oft’ from the imder side of the hammer, so that the end b\of the lever b, constituting the trigger may come under the finger a,and lift the hammer r. The lever or trigger b, turns on an axis Ir, and is constantly pressed on by a spring b\- The barrels are caused to revolve by means of the fingers d, attached by pin joints to the lever b, and these fingers act alternately on the series of inclined planes e, e, at the butt end of the series of barrels, as shown. e\ r, is the guard, similar to what has before been described. When this pistol is discharged the simple repetition of pulling the trigger will cause the series of barrels to be turned, and the hammer to be lifted and let go. When it is desired to revolve the series of barrels without lifting the hammer, then, by sliding a slide/, a projection f\ therefrom will move the finger a out of the way of the end bx of the lever b, so that the series of barrels may be revolved without acting on the hammer.
Having thus described the nature of my Invention, and the means of performing the same, I would remark that I do not confine myself to the exact forms or details of the parts, so long as the peculiar character of any part of my improvements l>e retained. But what I claim is, the so constructing triggers and spring hammers that the act of pulling a trigger shall remove the hammer from the cap on the nipple, and then allow the hammer to strike. T also claim the making part of the ramrod into a spring hammer. I also claim the use of a guard e\ e2. I also claim the so arranging a trigger that it shall cover or guard the cap. And I also claim the mode of turning the barrels of revolving fire-arms by means of fingers d, acting on inclines as explained.
In witness whereof, I, the said Joseph Rock Cooper, have hereunto set my hand and seal, this Nineteenth day of March, in the year of our Lord One thousand eight hundred and fifty.
