Patent No. Patentee Issue Date 1,545,045 Dute July 7, I925 3,341,963 Seiderman Sept. 19, 1967.

SUMMARY OF THE INVENTION Bolt action rifles are currently manufactured from designs essentially directed torrighhand shooters. Such left hand rifles as are commercially available generally comprise modifications, either custom or stock, of theee right hand design pieces. Often these are costly, and repair or replacement components are difficult to obtain. Previous attempts to provide convertible weapons, e.g., those wherein the bolt can be manipulated with the left hand, often result in difficulties with shell ejection in that, due to the fact that these rifles evolve from right hand weapons, the means for ejection of expended cartridge cases is meant to throw the case to the right or away from the shooter.

The present invention provides a rifle specifically designed to meet the needs of conversion by non-complex procedures from right hand to left hand operation involving only the reversal of position of four components. Such procedure may be readily accomplished without special tools and does not require extreme skill. The weapon may be inexpensively made if desired. In undertaking the conversion, it is simply necessary to remove and reverse the location of a single ejector lug, bolt actuating handle, and right and left extractors.

The weapon is neat in appearance, readily adapted for servicing, and positive in operation.

Other and further objects and advantages of the invention will become apparent to those skilled in the art from a consideration of the following specification when read in conjunction with the annexed drawings.

FIG. 5 is a further enlarged transverse cross-section on line 55 of FIG. 4, looking in the direction of the arrows;

FIG. 6 is a sectional view on line 66 of FIG. 5; and

FIG. 7 is a perspective view of the ejector.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings in more detail, a convert ible bolt action rifle according to this invention is therein generally identified by reference character 10. The rifle 10 has, as its three principal components, a stock 12 usually formed of wood or plastic, a barrel 14, and action 16.

The stock 12 comprises a forearm section 18 and a butt section 20 with a terminal butt plate 22. The forearm section has a groove 24 formed therein in which the bar] is bedded, and an enlarged receiver opening 26 is also formed in the stock. The barrel 14 has a threaded breech end 28 and a muzzle end 30. The breech has the usual longitudinally extending rifle bore 32, with an enlarged chamber 34 at the breech in which a cartridge is seated during firing. The stock and barrel, as described, are conventional and components from firearms of prior designs may be employed in the invention apparatus.

Unique to the invention however, is the action 16. The action comprises a receiver assembly 36, a bolt assembly 38, and a trigger mechanism 40.

The receiver assembly 36 includes a base 42 of substantially concave elongate form having a forward vertical slot 44 therein into which a cartridge dispensing clip 46 is projected. The clip is releasably retained thereat by a pawl 48 mounted on a pivot 50 and urged into clip retaining position by a spring 52. Both the pivot and the spring are mounted in trigger housing 40a, described below. Immediately aft of the clip slot 44, both the housing 40a and the base 42 of the receiver have coaligned openings 47, 49 formed therein. These serve a purpose appearing belowalso. Still further aft, the receiver has a trigger slot 51 therein.

Mounted in the trigger housing 40a is a trigger 53 which projects outwardly within a trigger guard 54. At its upper side the trigger is restrained by a spring 56, but carries an arm 58 which is movable downwardly to release the firing mechanism upon actuation of the trigger against the bias of the spring 56. The trigger mechanism further has a guide 60 mounted in a catch 62. The trigger housing is retained in place by forward and rear mounting screws 64, 66, respectively. The trigger and mount are standard also in construction and in operation.

The receiver 36 further includes sides 68 and 70 integral with the base 42 and an upper portion 72. All of these define a bolt slideway 74. The sides have cutaway walls 76, 78 and the top is removed at 79 thereabove to permit the ejection of expended shells, and the slideway is open at the forward and rear ends 80, 82 thereof. The end has a threaded extension 84 in which the end headspace. of the barrel is adjustably secured to the proper headsce.

The bolt assembly 38 includes a bolt body portion 86 of two-section formation comprising a forward portion 88 and a rear portion 90. The body portion 86is slidably mounted in the slideway 74 and is adapted for diassembly therefrom. The forward portion 88 has a compound passageway 92 formed therein in which a firing pin 94 reciprocally mounted; the latter having an impact receiving head 96 normally biased outwardly by spring 98. Referring to FIG. 6, it is there best shown that the leading end of the section 88 is cut away at its lateral portions 100, 102, and has a transverse hole 104 extending therebetween. Pivoted on vertical extractor screws 106, 108 in these portions are interchangeable pulling and support extractors 110, 112, the support extractor 112 being slightly long than the pulling extractor 110. Each has a forward tooth, including a square tooth 114 and an angular tooth 116, and the trailing portions are interconnected by a coil spring 1 18 which extends through the hole 104. The extractors are adapted to withdraw the casing C of an expended cartridge from the chamber of the barrel, by engagement of the tooth 114 with the casing flange F.

It will be understood that the location of the firing pin 94 will vary depending upon whether the firearm is of the center fire variety or rim fire variety (shown here, FIG. 4, wherein the firing pin end 120 of the hammer is off-center).

The lower side 122 of the forward section of the bolt is flat and has a pair of parallel, spaced apart off-center slots 124, 126 formed therein.

The rear portion 90 of the bolt includes a head 128 interengaged with the forward section. A bore 130 extends into this head, and a hammer 132 having a hammer head 134 is slidably disposed therein. The hammer similarly has a chamber 136 and terminates in a reduced end 137 with a coaxial threaded outer opening 138. A spring 140 is retained in said chamber and urges the hammer forwardly as hereinafter described. The hammer has a base lug 142 extending through a door 144 formed in the rear portion 90. The lug has forward and rear inclined cam surfaces 146, 148. Upon release of the trigger, the lug rides over the trigger arm 58, permitting the spring 140 to thrust the hammer head against the firing pin with resultant discharge of the firearm. 1

At this point, two important features of the invention will be described. A bolt actuating handle adapted for either right hand or left hand operation is generally designated at 144. Such handle comprises an angular sleeve 143 having an opening 145. Extending from the sleeve at one side is a curved rigid stem 147 with an outwardly spaced knob 149. The sleeve is dimensioned to fit about the reduced ends 137 of the end portion of the bolt. A screw 150 with a threaded shank 152 is threadedly engaged in the opening 138 and has a head 154 of a size great enough to overlap the sleeve and affix the same in place.

It will be observed that the position of the bolt handle is reversible. That is, the screw 152 may be removed, the handle turned 180, and the screw reinserted.

Such reversal of the bolt handle however, does not fully accomplish the purposes of the invention. In order to completely convert the rifle for opposite hand use, the direction of cartridge case ejection must also be reversible. To this end, the ejector 156 hereof is supplied, shown per se in FIG. 7. The ejector comprises a foot element 158 having a flat top 160 and a curvilinear lower surface 162. A central threaded opening 164 receives a screw 166 which extends through the openings 47 and 49. At an off-center location, the ejector has an upstanding lug 168 which is selectively engageable in the slot 124 or the slot 126, dependent upon the orientation of the ejection. As the casing is withdrawn from the chamber after firing in the grip of the tooth 114, supported by the tooth 116, the casing upon contact with the lug is forcibly ejected, either to the right or to the left depending on whether the lug is in the slot 124 or in the slot 126, and on the position of the respective extractors. As a necessary modification of the assembly, when the direction of expulsion of the casing is altered, the extractors 1 10 and l 12 must be interchanged so that the pulling extractor is located on the side to which the direction of ejection is desired. Continued movement of the bolt serves to again cock the hammer by retention of the base lug 142 behind the trigger arm.
