United States PatentOflFice 3,130,513 Patented Apr. 28, 1964 3,130,513 BOLT ACTION FIREARM WITH AUTOMATIC SAFETY MECHANISM ENGAGEABLE BY BOLT HANDLE Oliver M. Knode, Jr., Hampden, Mass., assignor to Savage Corporation, Westfield, Mass., a corporation of Delaware Filed Oct. 2, 1961, Ser. No. 142,162 7 Claims. (Cl. 42-70) This invention relates to bolt action firearms and more particularly to firing safety mechanisms for small arms.
As is well known, the function of a safety mechanism for firearms is to prevent inadvertent firing of the weapon. Any safety which must be intentionally actuated or placed on by the shooter leaves a great deal to be desired because it requires an additional human action other than that required to load and fire the weapon.
' This invention relates to a type of safety known as an The principal object of this invention is to provide an ,improved automatic safety forbolt action firearms.
Another object of this invention is to provide a safety of the above type of simple and inexpensive construction.
The above and other objects and advantages of this invention will be more readily apparent from the following description and with reference to the accompanying drawings in which: V g V 1 FIG. 1,is a partialside elevational view of a firearm embodying this invention; 1
'--. FIG. 2 is a view similar to FIGfl with parts in section and in which the safety mechanism is on;
FIG. 3 is a view similar to FIG. 2 in which the safety is in 01f position;
FIG. 4 is a section taken along line 44 of FIG. 2 showing the relationship of the safety and receiver; and
FIG. 5 is a plan view of the safety.
Referring in detail to the drawing, a firearm embodying this invention is shown generally at It). The firearm is a bolt-action type having a bolt 12 slidably and rotatably disposed within the receiver 14 of the weapon. The operation of the bolt is controlled by an operating handle 16 which extends radially outwardly of the bolt. The bolt handle 16 is rotatable in a plane perpendicular to the axis of the bolt and is rotated upwardly for unlocking and downwardly for locking the bolt in the receiver.
The bolt 12 may be of any conventional type and as shown comprises a striker 18 operated by a coil spring, not shown. The striker includes a lug 20 (FIGS. 2 and 3) which fits into a slot 22 in the receiver. The striker is held in cocked position by engagement of the lug 20 with a sear which forms part of the firing mechanism, shown generally at 26.
Depending from the undesired of the receiver, rearwardly of a bolt operating lever slot 24, is the firing mechanism of the weapon. The firing mechanism comprises a housing member 28 and includes spaced opposed walls 27 and 29 (FIG. 4) for pivotably supporting a trigger 30, sear 32, and safety mechanism 34.
The trigger is pivoted on a pin 36 which is supported by the opposed wall portions of the housing member 28.
The trigger includes a scar actuating finger 37 disposed ,ceiver. surface of the safety into frictional engagement with the outer surface of the receiver. vent unintentional movement of the safety. If necessary rearwardly of the pivot pin 36 and a notch 38 interengageable with the safety mechanism.
The sear 32 is pivotably supported by a pin 40. As shown, the sear is approximately L-shaped, including a downwardly extending leg 42 engageable by the finger 37 of the trigger. A coil spring 44, extending between the undersurface of the sear and the upper surface of the triggers urges both the sear and the trigger toward their prefiring positions. 5
In accordance with this invention, the safety mechanism 34 is in the form of a lever preferably of integral spring steel construction. The lever is pivotably mounted on a pin 46 for swinging movement in a plane normal to the plane of movement of the bolt handle 16. The lever comprises a U-shaped portion 51 defined by spaced walls provided with holes which receive the pin 46. This arrangement insures accurate rotation of the safety lever in a given plane. The lowerend of the safety comprises latch means interengageable with the trigger. When the safety is engaged with the trigger, the trigger cannot be moved, and consequently inadvertent or unintentional firing of the weapon is not possible.
As shown, the latch means comprises a finger 48 which fits into the correspondingly shaped notch 38 in the trigger. With the safety and trigger in this relative position (FIG. 2), the safety is on and the weapon cannot be fired since movement of the firing mechanism is prevented.
The portion of the safety, above the pivot pin 46, is in the form of an arm curved partially around the outer surface of the receiver 14 (FIG. 4). The inner surface of the safety is contiguous to the outer surface of-the re A projectionor detent 50 extends from the inner The detent serves to pre sitive assurance against inadvertent movement of the safety. I
The upper portion of the safety also includes a forwardly projecting hook or finger. 52. swingable for obstructing the opening of the bolt handle receiving slot 24. The finger 52 serves to actuate the safety in response to bolt operation and to prevent closure of the bolt handle if the safety should be moved off while the bolt is open, as shown in the broken line position of FIG. 3.
Lower edge 53 of the finger 52 extends forwardly at an oblique angle relative to the center line of the arm so that rearward pivotal movement of the safety occurs in response to upward movement of the bolt handle 16, as when the bolt is unlocked after firing. Thus, whenever the bolt is so moved, it serves to cam the safety rearwardly to its on position, since rearward movement of the safety causes the finger 48 to engage the notch 38 of the trigger. bus, when the bolt handle is operated to open the chamber of the firearm, the safety is automatically moved to its on position. Thereafter, the weapon may be loaded and the bolt closed in normal fashion. The safety remains on throughout these operations because of engagement of projection 50 with the receiver 14.
To fire the weapon, the safety must be off. This is accompanlished by moving its upper end forwardly so that the latch finger 48 is swung clear of the trigger and the finger 52 is swung into the path of movement of the bolt handle, so that whenever the bolt is subsequently opened the safety will be moved to its trigger locking position. An operating flange 54 is provided for convenience in manipulating the safety. The upper surface of the flange may be serrated and provided with an indicator arrow to show the direction of movement required to put the safety on.
Applicants invention provides a highly effective safety .3 mechanism which is operative to prevent unintentional discharge of a firearm. The safety is actuated automatically in response to operation of the bolt handle. Moreover, before the weapon can be fired, the safety must be moved to its 01f posit-ion in which it is disposed to be cammed .on by opening of the bolt. These desirable results have been achieved by means of a safety mechanism of simple and inexpensive construction which does not add substantially to the manufacturing costs of weapons equipped therewith.
