I, HENRY SCHLUND 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
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 A*
against the action of the spring, which forces it forward again when released.
The nose of the bolt being suitably rounded as shewn, it will be made auto-
matically 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 F, and thirdly the sear G working on the pin G¹, so
that on withdrawing the trigger guard as will be presently described all the above
named parts are removed therewith.

page_text: The hammer E is entirely enclosed within the frame, and is cocked by means of
the lever F, which has pivotted to it by a pin at H¹ the pawl H that takes into a
notch at E 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 H' 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 L 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 H². 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 E 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 F' L'G'
and H can now all be pushed out of their holes so as to separate the parts E FLGH
and I from the trigger guard.
Having now particularly described and ascertained the nature of my inven-
tion 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 GH
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.
