Application May 4, 1956, Serial No. 582,872 1 Claim. (CI. 42-70) This invention relates generally to firearms, and is more particularly concerned with a novel safety device for the reciprocable bolt of a firearm of the character utilized in a Winchester Model 54 rifle, for example, said novel safety being readily incorporated in the conventional bolt sleeve of such rifles or similar firearms without otherwise changing or modifying the rifle or any part thereof, providing a bolt assembly having a safety which is disposed laterally to one side of said bolt without interfering with the mounting of a telescopic sight longitudinally of the upper surface of the receiver portion of the firearm and adjacent the cocking piece of said firearm.

A primary object of invention is to provide in a bolt assembly which includes a reciprocable firing pin element, a novel safety which may be incorporated in the conventional bolt assembly without materially altering any of the conventional parts of the firearm, said safety being disposed in a readily accessible position adjacent the trigger finger of a user of the firearm thus permitting ready de-actuation of the safety to permit firing of the firearm without interference of the safety.

Another object of invention in conformance with that set forth is to provide in a firearm of the character involved which includes a receiver reciprocably supporting therein a bolt assembly incorporating a reciprocable firing pin element, a novel safety which includes a rotatable locking pin element journaled transversely of the bolt assembly in intersecting relationship relative to the firing pin element, the firing pin element including a transverse notch portion extending through the outer periphery thereof in alignment with the locking pin element, said locking pin element including a transverse notch portion overlying the notch portion of the firing pin element wherein rotation of the locking pin element will prevent reciprocable movement of the firing pin element and also permit said firing pin element to reciprocate through the notch portion of the locking pin element depending on the adjusted position of the locking pin element.

And yet another object of invention in conformance with that set forth is to provide a novel safety for a firearm incorporating a reciprocable bolt assembly incorporating a reciprocable firing pin therein, said safety being readily and economically manufactured and installed, easily maintained, and highly satisfactory, simple in operation, readily acceptable for the purpose intended.

These together with other objects and advantages which will become subsequently appaent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a fragmentary elevational view of a firearm showing the receiver portion thereof including a reciprocable bolt assembly having a reciprocable firing pin element, showing the novel safety installed thereon, said safety being shown in an on position to prevent firing of the piece;

Figure 3 is a side elevational view of the bolt assembly of Figure 1, with portions broken away and shown in section, showing the safety in an off position;

Figure 4 is a top plan view of the bolt assembly of Figure 3, with portionss broken away and shown in section; 7

Figure 5 is a sectional view taken substantially on line 5-5 of Figure 3;

Figure 6 is a fragmentary sectional view taken substantially on line 6-6 of Figure 2; and

Figure 7 is a fragmentary sectional view taken substantially on line 7-7 of Figure 5.

Referring to the drawings in detail, the fragmentary portion of the receiver portion of a Winchester Model 54 rifle is indicated generally at 10, said receiver portion reciprocably supporting therein in a conventional manner a bolt assembly 12 incorporating a cocking lever portion 14 and a reciprocable firing pin element 16. The heretofore described parts are conventional accordingly will not be described in detail except to the extent to which they cooperate with the novel safety device indicated generally at 18.

Referring to Figures 3 through 7 the firing pin element 16 has extending transversely through the upper outer peripheral portion thereof an arcuate notch portion 20, see Figures 3 and 6, and the safety device 18 includes a cylindrical locking pin element 22 which is journaled in a transverse bore portion 24, see Figure 7, which is in intersecting overlying relationship relative to the notch portion 20 of the firing pin element 16. The locking pin element 22 includes a transverse notch portion 26, see Figure 5, which is in intersecting relationship relative to the notch portion 20 of the firing pin element and when disposed in the position shown in Figures 3 and 5, for example, will permit reciprocable movement of the firing pin element 16 and accordingly firing of the firearm. It will be noted that the notch portion 20 of the firing pin element 16 is of an arcuate configuration permitting the locking pin element 22 to be readily rotated therein. Additionally, see in Figure 5, the notch portion 26 of the locking pin element 22 is also of an arcuate configuration conforming to the outer periphery of the locking pin element 16 thus permitting ready relative reciprocable movement of the locking pin element 16 relative to the pin element 26.

The locking pin element 22 includes on one end a laterally extending finger-engageable manipulating handle or lever 28 which is laterally disposed on a side portion of the bolt assembly 12 in a readily accessible position relative to the trigger 30 of the firearm, the lever 28 having a lower pointer portion 32 indicating the location of the notch portion 26 of the locking pin element, see Figure 1. When the lever element 28 is located in the position shown by the solid or dotted lines in Figure l, the firing pin will be retained in a relatively fixed position in the bolt assembly, and when the lever is disposed in the position shown in Figures 3 and 5, for example, the piece may be readily fired.

The bolt assembly 12 has extending into the rear end portion 34 thereof, a blind bore portion 36, see Figure 6, substantially parallel to the longitudinal axis of the firing pin element 16 and in intersecting relationship relative to the notch portion 26 of the locking pin element 22. The blind bore portion 36 has disposed therein a detent assembly comprising a coil spring 38 and a ball element 40 which is resiliently urged by the coil spring 38 into engagement with the outer periphery of a locking pin element 22 and extendable into the notch portion 26 of said locking pin element. The detent assembly aids in preventing accidental rotation of the lever 28 of the safety device 18 providing a residual drag on the locking pin element 22. The bore portion 36 is internally threaded at its rearwardly opening end for receiving therein a suitable screw element 42.

The locking pin element 22 includes at the end portion 44 opposite the lever 28 'an annular groove 46 extending about the outer periphery thereof, see Figures 4 and 7, for example. Said annular groove 46 being in alignment with an internally threaded bore portion 48 extending longitudinally in the bolt assembly 12. The internally threaded bore portion 48 includes therein a lock screw element 50 having a terminal pin portion 52, see Figures 4 and 7, for example, said pin element 52 extending into the annular groove 46 of the locking pin element 22 and thus preventing accidental transverse movement of the locking pin element 22 when the same is being rotated, and also permitting removal of said pin element 22 for replacement, for example.

In view of the foregoing, it is readily apparent that there has been disclosed a novel safety incorporated with a conventional bolt assembly which fully conforms with the objects of invention heretofore set forth.

Various positional directional terms such as outer, rear, etc. utilized herein to have only relative connotation to aid in describing the device and it is not intended to require any particular orientation with respect to any external elements.

The foregoing is considered as illustrative of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling Within the scope of the appended claim.
