Speccaton of Letters Patent.

Patented Apr. 23, 1912.

Application filed June 27, 1910. Serial No. 569,229.

To all whom it may concern:

Be it known that I, JOHN W. DowDEN, a citizen of the United States, residing at Reeves, in the parish of Calcasieu and State of Louisiana, have invented a certain new and useful Improvement in Firearms, of which the following is a specification.

My invention relates to a new and useful improvement in firearms, and has for its `object to provide a lock upon the loading yfrod to prevent the same from being operated until unlocked by the user.

Another object of the invention is to provide means for regulating the pressure of the spring which returns the breech block to its normal position.l

Another object of the invention is to provide a take-down spring, the end of which is bent inthe shape of a hawks bill, thereby preventing its end from coming in contact with the other parts of the fire arm, which would otherwise mar and break portions thereof. j

Another object of the invention is to form the cartridge stop in the shape of a hawk bill so that the breech block may readily slide over the same vwithout injuring it, the ends of said cartridge stop projecting into the magazine, thereby holding the outermost cartridge in place until the one in the barrel has been ejected.

Another object of the invention is to mount a spring upon the upper portion of the breech block, said spring carrying a roller adapted to operate against the upper portion of the receiver said spring and roller forcing the breech block downward so that it will be held in constant Contact with the cartridge stop, at the same time preventing rattling Vdue to the loose fit of the breech block within the receiver. f

Astill further object of the invention is to provide a hammer having two notches for i 'li-dengagement with the trigger, the uppermost notch engaging the trigger, if said trigger is held back, which will prevent the discharge of the firearm, the lower notch engaging the trigger after said trigger is released and from which position the firearm is discharged.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawing forming a part of this specification, in which- Figure l is a broken side elevation of a firearm made in accordance with my improvement, portions thereof being shown in section to more fully illustrate the construction. Fig. 2, an end view of the crown. Fig. 3, a side elevation of a portion thereof parts being broken away to show its construct-ion. Fig. 4, a rear or end view of the hammer. Fig. 5, a side elevation thereof. Fig. 6, a side elevation of the rod about which is coiled the spring for operating the crown. Fig. 7, an end view of the circular nut which is threaded on the rod shown in Fig. 6. Fig. 8, a side elevation thereof. Fig. 9, an end view of the loading rod. Fig. 10, a side elevation thereof showing a portion in section, and Fig. l1 a side elevation of the metal portion of the stock in which is pivoted the hammer, the end of the magazine being shown in section. Fig. 12, a longitudinal vertical section through the receiver and rear stock showing the hammer and trigger in their cooperative relations.

In carrying out my invention as here embodied, A represents the wooden stock and B the separable portion of the frame mounted upon the end of the wooden stock in any suitable manner. In the metal portion of the stock is mounted the take down spring C, the end of which is bent at right angles to form the hawk bill D, and this spring is adapted to engage the lower portion E of the front of the receiver F. This spring is preferably made in the shape of a hawks bill in order to prevent the end thereof catching in the edge of the receiver when the gun is being assembled.

G is the magazine which is mounted in the stock, the end thereof extending into the per portion of the cartridge stop J when said hammer is in its forward position, thus pressing the cartridge stop downward against the action of the spring L and causing its point O to engage the outermost cartridge in the magazine. By bending the end of the cartridge stop in this position it produces what is known as a hawk bill so that the same will engage the cartridge and at the same time eliminate the sharp ends or corners which might otherwise come in contact with the breech block and injure the parts thereof.

The hammer is provided with two notches P and Q, each of which is adapted to engage the trigger shown at R, the notch P being of greater depth in relation to the pivot point of the hammer so that if the trigger is held back, when the fire arm is re-loaded said trigger will engage the notch P and hold the hammer in its cocked position, but as soon as the trigger is released the hammer will move forward slightly until said trigger engages the notch Q, still holding the hammer cocked, from which position the firearm may be discharged when the trigger is pulled. From this description it will be seen that should the user of the firearm hold the trigger back and endeavor to reload it, the firearm will not be discharged until the trigger is released and then pulled.

R denotes the breech block, having an arm S which rests beneath the barrel T and is caused to reciprocate by the loading rod U. In the top of the breech block is formed the groove V, in `which is mounted the spring W, on the rear end of which is journaled the roller X, said roller operating against the inner face of the top of the receiver F, as plainly shown in Fig. 1, the action of the spring holding the breech block downward or in close proximity to the cartridge stop J.

The arm S is beifurcated so that it straddles t-he lug Y carried by the receiver and in this lug is threaded the rod Z, the end of which extends through the outer end or bridge A of the arm S. About this rod is coiled the spring B, one end resting against the bridge of the arm, the opposite end against the circular nut C which is threaded upon the rod Z. This nut is provided wit-h a number of wrench holes D whereby the same may be threaded along the rod for regulating the pressure of the spring B.

The loading rod U is provided with two chambers D2 and E leading from the opposite ends thereof, the chamber D2 having a coiled spring F mounted therein, one end of which rests against the top of said chamber, the other end against the rod Z. In the chamber E', is also mounted a coil spring H', one end of which rests against the inner end of said chamber, the opposite end carrying a plunger I which engages the nose J of the knife edge lock K, which is pivoted to the cap L at M, said cap being mounted upon the end of the loading rod U.

Over the rod Z the arm S of the breech block and the loading rod is placed, the fore stock N. Over the end of the fore stock N is placed the tip O against which rests the outer end of the lock K when the same is parallel with the loading rod, which will preventany movement of said loading rod until said lock is drawn downward by the user of the fire arm.

In practice the metal portion ofthe stock is inserted in the receiver, the take down spring C engaging the under side E of the receiver which will force the metal portion B of the stock upward, at all times taking up any slack between the parts, the carfg tridge being in the magazine. To load the' gun, the lock K is drawn downward, then by pushing rearwardly on the loading rod U, the inner end of which rests against the bridge of the breech block arm, said breech block will be forced rearwardly against the action of the spring B, the tension of which has been regulated by the nut C mounted upon the rod.Z. The spring W on top of the breech block will normally hold said breech block depressed, the roller X on the end of said spring allowing the same to move with little friction, and as the breech block is moved rearwardly the hammer M will be cocked, removing the pressure from the cartridge stop J, so that the point O disengages the cartridge. in the magazine, allowing it to move forward to the barrel. When the loading rod is released the spring B will draw the breech block to its normal position, the spring F assisting in relieving the pressure of the loading rod upon the arm S. If in this operation the trigger has been held back it will engage the notch P of the hammer so that said hammer cannot fall to discharge the lire arm, and as soon as the trigger is released it will engage the notch Q, at which tim-e the fire arm may be discharged in the ordinary'manner.

Of course I do not wish to be limited to the exact details of construction here shown, as these may be varied within the limits of the appended claims without departing i from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful, is-
