Patent: Joseph Rock Cooper

British 12781



Joseph Rock Cooper, of Birmingham, in the County of Warwick, Gun an being then placed over the nipple, the barrel is to be again turned into position, which will bring the end of the spring c, so that it will press on the cover d. This arrangement, although only shewn applied to a pistol, may, with slight modifications of the parts, he applied to guns and fowling pieces. Figure 4, shows an under side view. Figures 5, and 6, show a side and end view of a pistol having a similar improvement to that above described applied thereto, together with other improvements. In this arrangement, in place of having the spring c fixed to the barrel, as in the former pistol, the spring -c forms the one end of the ramrod, and there is a guard e\ used to the ring d}> (or other formed end of the lever cl, cZ1,) such guard preventing the ring being moved back, unless the guard (i1, be first moved so as to unlock the guard. Figure 7, shows two views of the ramrod separately, by which it will be seen that the one end thereof acts as a spring hammer, and also the means of keeping the cover tl close. The ramrod passes through the sling/, so that when it is drawn out (to admit of the cover d being placed in position over the nipple) it can be used for ramming down, but the sling prevents it being separated from the fire-arm. The ramrod passes through the socket;/, and when pressed home, as shewn at Figures 4, and 5, it rests on and retains the cover d secure, till that cover is moved away, as shewn by the red lines in Figure 5; then the end of the spring c, acts as a spring hammer, and strikes the cap on the nipple, and the cover d can only be moved away by pressing the lower end of the guard out of the ring, which will move the notch or catch moving on its axis, as will be readily traced by examining the Drawing, more particularly the several detached views of these parts shewn at Figure 8. This apparatus, like that first described, may be applied to fowling pieces and other fire-arms. I have not, however, thought it necessary to show the same so applied, as a workman will readily apply the several improvements thereto.

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.


AND BE IT REMEMBERED, that on the Nineteenth day of March, in the year of our Lord 1850, the aforesaid Joseph Rock Cooper came before our said Lady the Queen, in Her Chancery, and acknowledged the Specification aforesaid, and all and everything therein contained and specified, in form above written. And also the Specification aforesaid was stamped according to the tenor of the Statute made for that purpose.

Enrolled the Twentieth day of March, in the year of our Lord One thousand eight hundred and fifty.
