IVER JOHNSON AND ANDRFV FYRBERG, OF VORCESTER, MASSACHUSETTS; SAID FYRBERG ASSIGNOR TO SAID JOHNSON.
REVOLVER.
SPECIFICATION forming part of Letters Patent No. 465,179, dated December 15, 1891.
Application filed March 12,1889.
To all whom it may concern:
Be it known that we, IvER JOHNSON and ANDREW FYRBERG, citizens,V of the United States, and residents of Vorcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Fire-Arms, of which the following is a specification, reference being had to the accompanying drawings, forming a part of the same, in which- Figure 1 represents the frame of a revolving iire-arm,shown partly in section, and also exhibiting a portion of the lock mechanism. Fig. 2 is a detached vieWI of the trigger with the pawls for actuating the cylinder and hammer pivoted thereto. Fig. 3 is a sectional view of the mainspring on line X, Fig. 1. Fig. 4 is a detached and top view of the mechanism for locking the hammer against cooking. Fig. 5 is a detached view of the hammer with the hammer-locking mechanism shown in sectional vieW on line X', Fig. 4. Fig. 6 represents the same parts las are shown in Fig. 5, but with the hammer-locking mechanism in a diiferent position, allowing the hammer to be cocked. Fig. 7 represents a modified form of the portion of the lock shown in Fig. 1, and Fig. 8 is a detached view of the hammer-actuating pawl.
Similar letters refer to similar parts in the different iigures. Y
Our invention relates to the lock mechanism of fire-arms; and it has for its objects to so arrange the operating parts that the hammer shall be actuated in the operation of liring and the hammer-cooking mechanism connected with the trigger shall be reversed by the force of the mainspring; and, further, to securely lock the hammerfrom being inadvertently cocked.
In the accompanying drawings, A denotes the frame of the fire-arm, a portion having been removed in order to disclose the lock mechanism, only such portions of the lockv mechanism' being shown as are concerned in our present invention.
, B denotes the hammer, pivoted at B and provided with a notch B2, which is engaged by the projecting lip C of the pawl or raiser C, which is pivoted at C2 to the trigger D.
The trigger D is pivoted to the frame at D',
Serial No. 303,036. (No model.)
and to the Wing D2 is pivoted the pawl C, by which the hammer is actuated in the operation of cooking, and also the pawl E, by which the cylinder is rotated in the usual and wellknown manner.
The mainspring F is preferably formed in a single piece, connected to the frame A by a pin Fl and having the two leaves F2 F3. The leaf F2 bears with its free end against the shoulder B3 of the hammer B, and the leaf F3 is provided at its free end with the blade F4, arranged in a vertical plane and resting upon the wing D2 of the trigger D. The tension of the mainspring F is thereby applied to force the hammer forward against the firing-pin, and also to move the wing D2 downward and carry the trigger forward by the action of the leaves F2 F3.
As the trigger D is brought back in the operation of cooking the hammer, it is rotated about the pivot D', lifting the pawl C, and
by means of the engagement of the lip C with the notch B2 the hammer is rotated A about its pivot B', the action of the trigger and hammer, as described, bringing the leaves F2 F3 of the mainspring F closer together until the face a of the tumbler B4 of the hammer is brought against the side of the pawl O, forcing the lip C out of the notch B'2 and allowing the tension of the mainspring F, eX- erted through the leaf F2, against the shoulder B3 of the hammer to carry the hammer violently against the `tiring-pin in the usual manner. As the trigger is released, the leaf F3 of the mainspring serves-to carry the trigger forward into its normal position.
In the construction shown in Fig. l the pawl C is held against the hammer by means of Va small spring b, in the present instance attached to the pawlE and acting against the pin c in the pawl C. The two pawls are thereby thrown apart, the pawl C being held against the hammerV and the pawl E being pressed forward to engage the ratchet-teeth upon the cylinder, which have not bden shown in the drawings, as the action of the cylinder-pawl formsno part of our present invention.
In the case of fire-arms other than revolving the cylinder-pawl is not required andthe joint action ofthe spring b can be dispensed. with. YVe actuate the hammer-pawl, as well IOO .the free end of the latch in position to enas the trigger, in such cases by means of the leaf F3 of the mainspring F, by means of the construction shown in Figs. 7 and 8 of the drawings. The pawl C is provided with a shoulder d, Fig. 8, h aving an inclined wall c, forming the point f, upon which the blade F4 of the leaf F3 of the mainspring rests. As the point f is at the left of a vertical line drawn through the center of the pivot C2, Fig. 7, it is obvious that the downward presspure of the leaf F3 upon the point f will not only serve to carry the trigger forward, as has already been described, but will also act to rotate the pawl C upon its pivot C2 and hold the upper end of the pawl against the hammer, causing the lip C to engage the notch B2 in the hammer B. Although the mainspring F, as shown, is preferably made in a single piece, the action of the two leaves F2 and F3 is independent, and the leaves can be made in separate pieces and attached to the frame A, if desired. The hammer is locked against the action of cocking bymeans of the device shown in Fig. l and in detail in Figs. 4, 5, and 6.
The hammer B is provided with a shoulder v g, which is engaged by the latch G, pivoted upon a pivotal pin G', held in the frame A, as shown in Fig. 4 and in section in Figs. l, 5, and 6. The pivoted end of the latch G is inclosed by the sides 1 and 2 of the bifurcated sliding block H, which projects th rough the frame A, mortised at H for the purpose, and slides upon the pin G', which passes through a slot H2. A spiral spring H3 is inserted in the block H, its ends resting against the Wall h of the block H, and the` pivoted end of the latch G serving to press the sliding block H away from the end of the latch H and in the positions shown in Figs. l and 5. The latch G has an inclined or cam surface at j, and the sides of the block H carry a pin H4 in contact with the inclined surface of the latch. In the normal position of the several parts, as shown in Figs. 1 and 5, the latch is made to rest upon the pin H4, holding gage the shoulder g of the hammer and prevent the rotation of the hammer in the operation of cooking. By pressing against the projecting endH5 the sliding block H is moved forward, compressing the spiral spring H3 and sliding the pin H4 over the inclined surfacej, thereby raising the free end of the latch G so it will clear the shoulder g of the hammer, allowing it to be cocked. The position of the several parts of the hammer-locking device as assumed when the sliding block H has been pushed in is shown in Fig. 5, in which the pin H4, carried by the sliding block H, is shown as having moved across the inclined surface j and raised the free end of the latch G to allow the hammer to be moved. The sliding motion of the block H is limited by the slot H2, thereby limiting the movement of the pin H3 to the traverse of the inclined surface j of the latch G. The spring H3 is applied to the end of the latch G at a point above the center of the pivotal pin G', so that the tension of the spring H3 not only serves to press the sliding block H outward and away from the pivoted end of the latch G, but also to rotate the latch upon its pivotal pin G and carry the free end of the latch downward in position to engage the shoulder g of the hammer B, in which position it is supported by the pin H4.
We are aware that it is not new to lock the hammer of lire-arms from movement in the action of cocking. Such We do not claim, broadly.

A. PYRBERG. LOOK FOR REVOLVERS.
No. 566,393. Patented Aug. 25, 18.96-
UNITED STATES PATENT OFFICE.
ANDREW FYRBERG, OF l/VOROESTER, MASSACHUSETTS, ASSIGNOR TO IVER JOHNSON, OF SAME PLACE.
LOCK FOR REVOLVERS.
SPECIFICATION forming part of Letters Patent No. 566,393, dated August 25, 1896.
Application filed October 2, 1891.
To (til whom it may concern:
Be it known that LANDREW FYRBERG,a citizen of the United States, residing at Worcester, in the county of WVorcester and State of Massachusetts,have invented certain new and useful Improvements in Firearms, of which the following is a specification, accompanied by drawings forming a part of the same and to which reference is herein made.
My invention relates to an improvement in the firing mechanism of firearms, and the object is to provide the firearm with a safety firing mechanism which will prevent the discharge of the firearm by any action of the hammer except as released by the trigger.
In the accompanying drawings, Figure 1 represents a firearm embodying my invention, a portion of the framework having been broken away in order to disclose the lock mechanism and the device embodying my invention, the several operating parts being shown in their normal position. Fig. 2 represents the firearm shown in outline with the hammer placed at full-cock, and Fig. 3 represents the same with the operating parts in the position assumed at the moment of discharge.
Similar letters refer to similar parts in the several figures.
In the accompanying drawings I have shown my invention as applied to a revolver of the usual form of construction. It is, however,
- adapted to all firearms in which the discharge is efiected by means of a lock mechanism.
In Fig. 1, A denotes the frame; B, the re volving chamber-cylinder O, the hammer ro tating upon the pivot C and actuated by the mainspring C D denotes the trigger, turning upon a pivot D and carrying, pivoted thereto at D the pawl E, provided with a spur E, engaging the notch 0 upon the hammer.
Pivoted upon the pawl E at F is a cylinderpawl F, by which the cylinder B is rotated in the usual manner. A blade-spring a, acting jointly upon the pawls E and F, serves to bring them into engagement with the hammer C and cylinder B, respectively. The hammer is provided with a notch b, which is engaged by the sear G, thereby holding the hammer in position at full-cock. So much of the construction and operation as relates Serial No. 407,516- (No model.)
to that portion of the lock mechanism already described will be readily understood, as it is substantially the same as is now in common use.
My invention relates to the mechanism, hereinafter described, by which-the discharge of the firearm is prevented by any action of the hammer independently of the movement of the trigger. Sliding in the frame is a firingpin H, arranged to be driven against the cartridge-head by the action of the hammer and retracted by the spiral spring I in the usual manner. The hammer C is provided with a face J, which is brought against the frame at 6 J in the operation of discharging the firearm, thereby limiting the movement of the hammer. Below the face J the hammer is cut away, forming a face J which clears the end of the firing-pin H when the hammer is in the position shown in Fig. 1. When the hammer is brought to the position of full-cock and retained by the sear G, it is released by the backward motion of the trigger D against the sear G, causing it to rock upon the pivot G and releasing the hammer G, which is carried into the position shown in Fig. 3 by the action of the mainspring C The rearward motion of the trigger D in the operation of releasing the hammer carries the pawl E upward, so as to bring the end E into the path of the hammer and between the face J and the rear end of the firing-pin H, so that the blow of the hammer will be received by the end E of the pawl E, and through the end IE will cause the 8 5 firing-pin to be pushed forward against the cartridge-head.
When the trigger D is released, it is carried forward into the position shown in Fig. 1 by a blade-spring held in the frame and not shown 0 in the accompanying drawings,as its construction and operation will be fully understood. The forward movement of the trigger D into the position shown in Fig. 1 will be pressed, the pawl E withdrawing the end E from between the face J 2 of the hammer and the end of the firing-pin H and bringing the spur E into proper position to engage the notch C in the hammer as the pawl E is thrown backward by the action of the spring F, causing too it to assume the position represented in Fig. 1.
If the hammer C be raised and released from,
any position other than a full-cock, the blow will be received upon the face of the frame J and the face J of the hammer without moving the firing-pin, for the reason that the end E of the pawl E will not have been lifted high enough to be caught between the face J 2 of the hammer and the end of the firing-pin I'I but in case the hammer is raised to a fullcock it then becomes locked by the act-ion of the sear G and prevented from discharging the firearm except as it is released by the rearward movement of the trigger D, which also serves to elevate the end E into the path of the face J 2 of the hammer and interposing it between the hammer and the firing-pin II.
It will be obvious that the essential feature of my present invention as herein described does not depend upon the specific construction and arrangement of the operating parts comprising the lock mechanism. For example, in the mechanism shown the hamm er-lifting pawl E is extended at E to be interposed between the face J and firing-pin H; but the part E, which in the present construction forms a single piece, might be made in separate pieces and hinged to the trigger, or a separate lifting-pawl engaging the hammer could be pivoted upon E, and instead of the notch (J engaged by a spur E a shoulder or tooth might be formed on the tumbler of the lock adapted to be engaged by a liftingpawl.
I do not confine myself to a spring-retracted firing-pin, as shown, the essential feature of my present invention consisting of a piece interposed between the face of the hammer and the firing-pin at the releasing of the hammer by the rearward movement of the trigger and the withdrawal of said interposed piece, except upon the releasing of the hammer by the trigger, and in forming the face of the hammer so as to clear the firing-pin when the in terposed piece has been withdrawn.
I am aware that the firing-pin has been provided with a shoulder upon one side of the pin adapted to be struck upon its rear face by the hammer, but which is capable of being carried out of the path of the hammer by the rotation of the firing-pin itself, and I do not therefore herein claim such a construction. The firing-pin in my device is capable of a longitudinal movement only, forward as impelled by the blow from the hammer and rearward as retracted by a spring, thereby simplifying the construction of the lock, and I interpose an independent piece between the face of the hammer and the rear end of the firing-pin, whereby the force of the blow exerted by the hammer is exerted directly in a line coincident with the axis of the firingpin, which is not the case when the pin is struck upon a shoulder projecting from the side of the pin.
What I claim as my invention, and desire to secure by Letters Patent, is
1. In a firearm, the combination with the frame of a firearm, of a firing-pin, a pivoted hammer provided with the faces J and I, with the face J arranged to strike the frame and receive the blow of the hammer and with the face J in alinement with the firing-pin, an interposing piece, and means for inserting said interposin g piece between said firing-pin and said face J 2 of the hammer, substantially as described.
2. In a firearm, the combination with a firing-pin and a hammer arranged to clear said firing-pin, and a pivoted trigger and a piece hinged to said trigger and interposed between said hammer and said firing-pin by the movement of the trigger in releasing the hammer, whereby the blow of the hammer is made to actuate said firing-pin, substantially as described.
3. The combination of a firing-pin, a hammer provided with a notch or tooth by which it is engaged by a scar when at full-cock, a sear engaging said notch, or tooth, a trigger by which said sear is disengaged and the hammer released, and an interposing piece operatively connected with said trigger, and arranged to be carried between said firing-pin and the face of the hammer by the action of said trigger in releasing said hammer, substantially as described.
4. The combination of the firing-pin, hammer arranged to clear said firing-pin and provided with a notch to be engaged by a lifting-pawl and a notch or tooth to be engaged by a retaining-sear when the hammer is at full-cock, a scar engaging the hammer, a trigger operating to disengage said sear, a lifting-pawl carried by said trigger and engaging the hammer, said lifting-pawl having its free end extended between the face of the hammer and the firing-pin as the sear is disengaged from the hammer, substantially as described.
