A. J. SAVAGE FIREARM Filed Sept. 10. 1919 Patented June 16, 1925.,

ARTHUR J. SAVAGE, OF SAN DIEGO, CALHORNLA.

Application filed September To all whom it may concern:

Be it known that I, ARTHUR J. SAVAGE, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented new and useful Improvements in Firearms, of which the fol lowing is a specification.

This invention relates to fire arms, and more particularly to rifles of the single-shot type, and it has for its object to provide an improved fire arm of the general character stated which will be superior in point of relative simplicity and inexpensiveness of construction taken in conjunction with safety and efiiciency in operation, quickness in loading and'shell ejection, and positiveness and general superiority in performance and operation.

With the above and other objects in view, the invention consists in the novel and useful provision, formation, combination, association, cooperation and inter-relation :of parts, members and features, all as hereinafter described, shown in. the drawing and finally pointed out in claims.

In the drawing:

Figure 9 is a rear end view of the sight as shown in Figures 7 and 8;

Figure 10 is a side elevation of the trigger shown in combination with the other parts in Figure 2, the same being in detached position; and,

Figure 11 is a fragmentary vertical sectional view, taken upon the plane of the section in Figure l, and showing the co-action of the sear and firing pin and trigger, when the firing pin is cocked and ready to be released by manipulation of the tr1 ger.

Corresponding parts in all the gures are designated by the same reference characters.

Referring with particularity to the drawing, A designates the barrel of a rifle which is provided at its rearward end with asuitable chamber for the reciprocating breech bolt C, The barrel is supported by the stock I), and is connected therewith by the take-down screw 12. The stock is provided with the usual grip 13. A cut-away portion or opening 14 is between the rearward end of the barrel and the forward end of the rearward barrel extensionv or housing 15. which is, as stated, mounted on thedstock to accommodate the reciprocating breech bolt, reduced at its forward end, and provides an ejection opening for exploded shells, and likewise accommodates the insertion of loaded cartridges in a position to be forced into the barrel upon the forward movement of the breech bolt. Within the breech bolt, which is tubular, is the longitudinally moving tubular firing pin d, which firing pin houses the main spring 6 between its front end and the retainln pin f. The breech bolt C is locked ready or firing by turning it through the agency of the breech bolt handle 16, so as to bring it behind a shoulder- 16 in the housing 15, in accordance with ordinary military bolt action fire-arms practice. The firing pin d is cooked by manually drawing rearwardly the knurled head 17 fastened to the firing pin by means of a holding pin 18. This puts the main spring e under compression, the retaining pin 7 being accommodated, in the travel of the firing pin d, by an elongated slot 19. The main spring a is thus positioned between the retainln in f and the forward end of the tubular ring pin (1, acting in its expansion to carry forward thecfiring pin, with its operative nose 20, so as to bring such nose into firing engagement with the loaded cartridge position in the barrel.

' cartridge The firing pin is held in rearward or retracted position prior to firing, by the sear D, which is pivoted on the pin 22, and the sear is held in this position by the action of the trigger E, pivotally mounted as at 23 and having a nose 23 entering a recess 23 in the sear. The trigger and sear are held in these cooperative relations by the trigger spring 24. The trigger and sear and trigger spring 24 are accommodated in the usual manner in a suitable chamber 25 produced vertically through the stock 6, and the trigger projects beneath the stock, where it is enclosed within the usual trigger guard 26. When the trigger is pressed by the finger of the operator, the spring 24 is compressed, the trigger is oscillated upon its supporting pivot pin 23, the nose 23 is depressed in rocking engagement with the sear D in the recess 23, and the sear is depressed so as to withdraw it from engagement with the firing pin and permit the firing pin to execute its firing m'otion under urgence of the main spring e.

As the breech bolt handle 16 leaves the.

housing 15 entirely upon rearward travel of the bolt C, it is necessary that the bolt be guided to keep the said bolt from rotating on its longitudinal axis and thus getting out of alignment, or bringing its associated parts out of ali ment. To accomplish this,

I provide a trigger extension 27 which is received within a groove 27 in the under side of the breech bolt and prevents the bolt from turning. This trigger extension is directly over the trigger pin 23, and the roove 27 extends the entire length of the fiolt in the lower walls thereof and permits the bolt to be removed for cleaning, etc.

The bolt-carrier extractor F, in conjunction with the trigger-and-sear combination, .under pressure of the spring 24, ejects the case, or exploded shell, 28, through the cooperation of the shell rim and the upper surface of the sear D. It is to be particularly noted that the sear is provided with a beveled shoulder or face 22.

This beveled face or shoulder acts to eject the shells. Without this face 22 the shells would not eject and the arm would be of no use.

' The entering of the cartridge into the barrel chamber is accomplished by means of the loading platform 29, particularly shown in Figure 3, which is beveled or rounded at its rear end to guide the cartridge into position to align it with or register it with the barrel chamber.

bolt. When the trigger is operated to release the firing pin, the key 30 is withdrawn from this accommodating slot, thus permitting rotation of the breech bolt. The key 30 is withheld from the said slot after the firing action, so that the bolt C can be rotated, by the sear which acts to that end upon the trigger under downward pressure of the advanced firing pin.

The breech bolt G is stopped in its rearward movement by the co-action of the key 30, at its forward end, with a rearwardly facing shoulder 30 on the breech bolt.

To remove the breech bolt C, all that is required is to draw these last mentioned coacting shoulders apart by pressing upon the trigger, whereupon the breech bolt may be rearwardly moved.

Itis obvious that the fire arm can be readily taken apart or taken down by loosen- \ing the thumb screw or take-down screw 12 by its head 31 and thus removing the stock from the barrel.

The rear sight is constructed so that quick vertical adjustment may be obtained by rotating the knurled nut 32 which is threaded to the eye piece 33 having the peep aperture or opening 34. The sight base is fastened to the barrel by means of a screw 35. A tension is maintained at all times on the knurled nut 32 by means of a leaf spring 36, one end of which is held by the screw 35 and the free end of which presses on the nut. Protecting walls 37 are arranged at the sides of the sight, shielding and protecting the adjustable eye piece 33 from blows or knocks that might disengage it or interfere with its true alignment and proper mounting and disposition. It is obvious that these may be shaped in any desired fashion to more or less completely surround and house the eye piece with its peep opening.

It is obvious that many variations and modifications and alterations maybe made with respect to the construction and interrelation of parts and features herein described and shown in the drawing, all without departing from the true splrit of the invention and a proper interpretation of the following claims:

Having thus disclosed my invention I claim and desire to secure by Letters Patent:
