Improved Revolver Action.
I, Henry Schlung of The Kynoch Gun Factory, Aston Cross, Birmingham in the County of Warwick, Civil Engineer do hereby declare the nature of my invention for “Improved Revolver Action” and in what manner the same is to be performed to be particularly described and ascertained in and by the 5 following statement:—
My invention relates to an improved revolver action whereby safety in locking, is obtained, together with simplicity in the construction of all the parts which are less in number than with revolvers of present construction, the construction being such that the parts can be taken to pieces without the use of a tool, and that the hammer is entirely enclosed.
The construction will be readily understood on reference to the accompanying drawings, in which Fig. 1 shews a longitudinal section of the revolver with the barrel closed; Fig, 1ᵃ shews a perspective view with the barrel in the open position, Figs. 2 to 5 shew detached details.
For locking the barrel a curved sliding bolt A sliding in curved grooves in the framing as shewn in the section at Fig. 5 is provided, which bolt is forced forward by a spring A¹ so as to enter a notch B¹ in the rib B on the barrel; this rib has a slot which, in closing, fits over a tongue C, forming part of the lock frame, so that by means of this tongue and the bolt A the barrel is securely locked in the closed position.
For releasing the barrel, the bolt A is drawn back by means of a thumb piece A² against the action of the spring, which forces it forward again when released.
The nose A² of the bolt being suitably rounded as shewn, it will be made automatically to spring into the notch B’ when the rib is closed down again.
The trigger guard D, shewn detached at Fig. 2, is secured in position firstly by a tongue D¹ overlapping a bevil on the frame, secondly by the part D³ fitting into a recess, and thirdly by a screw at Z with a milled head so that it can be unscrewed by the hand; it has pivotted to it firstly the hammer E, working on the pin E¹, which is of the configuration shewn in the detached view at Fig. 3; secondly the lever F working on the pin F¹, and thirdly the sear G working on the pin G, so that on withdrawing the trigger guard as will be presently described all the above named parts are removed therewith.
The hammer E is entirely enclosed within the frame, and is cocked by means of the lever F, which bas pivotted to it by a pin at H¹ the pawl H that takes into a notch at E² of the hammer, so that on pressing upon the lever F with the middle finger, the pawl H forces back the hammer into the dotted position, in which it is held by the sear G entering the notch at E³. Upon the pin H¹ is also mounted the pawl or “lifter” I that effects the step by step rotation of the cylinder, and which is held up against the latter by the lever J, acted upon by the main spring K and shewn detached at Fig. 4. This lever at the same time presses upon a shoulder on the side of the sear, thus keeping this engaged with the hammer, On pressing with the fore finger against the trigger L (pivotted to the lever F at L¹) for firing, the part L² thereof acts on the tail G² of the sear so, as to release the hammer therefrom, this being at the same time released from the pawl H. by the trigger pressing upon its tail H®?, The hammer is now thrown forward by the spring K and after firing the charge, is cause to rebound slightly so as to be clear of the cylinder; this is effected by the pressure of the tail K¹ of the spring upon the lever J which in its turn presses with a rib J¹ upon the tail E⁴ of the hammer so as to force it back somewhat.
For taking the action to pieces the pin Z is first unscrewed by its milled head, and the plate M together with the stock N, is then withdrawn from the frame O; the main spring K can then be detached from the hammer and taken out, thereby permitting also the removal of the lever J. The trigger guard D with the before-mentioned parts attached thereto can now be drawn out by first drawing it slightly downwards so as to relase the parts D¹ and D³ that are engaged with the frame, and then shifting it to the left hand somewhat. The several pins E¹ F¹ L¹ G¹ and H¹ can now all be pushed out of their holes so as to separate the parts EF LGH and I from the trigger guard.
Having now particularly described and ascertained the nature of my invention and in what manner the same is to be performed I declare that what I claim is
1. The use of the sliding spring bolt A for locking the barrel in the closed position, substantially as herein described.
2. The construction and arrangement of the trigger guard D secured in position by the tongue D¹ and screw pin Z, with milled head, so that on removal of the said pin by hand the trigger guard with the several parts of the lock action attached thereto can be withdrawn substantially as herein described.
3. The combination with the trigger guard of the several parts E F L G H and I arranged and operating substantially as herein described.
4. The arrangement of the hammer E entirely enclosed within the handle of the revolver, substantially as herein described.
5. The combination of parts constituting an improved revolver action as herein described with reference to the accompanying drawings.
