Description

' BREECH BOLT MOVED BY RIFLE GRIP Filed April 7, 1958 ATT D-KNEY United This invention relates generally to rifles and particularly to an improved mechanism for reciprocating the rifle breech bolt.
The principal object of this invention is to provide means for manipulating the breech bolt of a rifle wherein the user of the rifle does not need to lift his hands from the rifle stock.
An additional object is to provide means for reciprocating the breech bolt of a rifle that will aid the rifle user in holding the rifle on his target while the breech bolt is being reciprocated.
Rifles of the type having reciprocating breech bolts are well known and widely used. Difliculty is encountered, however, in reciprocating the breech bolts during operation of a rifle of this type in that the rifle user must lift his hand from the rifle stock and away from the rifle trigger to grasp and manipulate the breech bolt and thereafter return his hand to the rifle stock and the trigger to fire the rifle. Movement of the users hand in this manner, in many cases, will spoil the aim of the ,rifle, with the result that successive shots will be separated widely. It is to overcome the above and other disadvantages inherent in rifles having reciprocal breech bolts that I have developed my improved means for operating the rifle mechanism.
Additional advantages and objects of my improved mechanism will be obvious to those skilled in the art when the following specification is read in the light of the attached drawings. While I will describe my invention with a certain degree of particularity, it should be understood that the specification and drawings are by way of example and illustration only and should not be construed as a limitation.
In the drawings illustrating a preferred embodiment and wherein like numbers refer to like or similar parts.
Figure 1 is a side elevational view of a standard rifle and breech bolt mechanism.
Figure 2 is an enlarged side elevational view of a rifle stock and breech bolt mechanism modified in accordance with my invention and illustrating movement thereof in dotted lines.
Figure 3 is a bottom plan view of a rifle stock and breech bolt mechanism modified in accordance with my invention and shown in the open position.
Figure 4 is a broken away sectional view of the rifle stock holding rod.
As best seen in Figure 1 in the drawings, there is illustrated a more or less standard rifle consisting of a barrel 1 which has fixed thereto a rifle stock composed of the barrel portion 2, grip portion 3 and butt portion 4. A reciprocating bolt 5 is contained in the breech of the barrel 1 and the bolt 5 is manipulated by a stud 6 projecting at the side of the rifle stock where it may be grasped conveniently by the user. A trigger 7 to release the firing pin of the bolt 5 projects below the rifle stock and is enclosed by a trigger guard 8 as is common.
In use, the rifle, in this case, is held against the right shoulder of the user with the right hand of the user encircling the grip 3 and with the forefinger in position on the trigger 7. To manipulate the bolt 5, the right hand of the user must be removed from the grip 3 to grasp the stud 6 and manipulate the bolt 5 and thereafter return to the grip 3 to fire the rifle.
rates atent ice In modifying the conventional rifle as illustrated in Figure l in accordance with my invention, I separate the rifle stock into three parts: the barrel portion 2, the grip 3, and the butt 4. The barrel portion 2 is then fixed to the barrel 1 in the conventional manner and the butt portion 4 is then secured to the barrel portion 2 by the rod 9 which is secured threadably at its forward end 10 in the socket 11 in the barrel portion 2 and maintained therein by the grub screw 12 or like means. A plate 13 is secured part way down the rod 9 and the butt portion 4 is held rigidly against this plate by the nut 14 engaging on the opposite end of the rod 9. To conceal the nut 14, a counterbore 15 is provided in the butt portion 4 and a shoulder pad 16 is secured on the butt portion as is common in rifle construction. It will now be obvious that I have provided a rifle stock composed only of the barrel portion 2 and the butt portion 4 spaced apart and secured to the barrel 1 in the conventional manner.
The stud 6 is removed from the rifle bolt 5 and the rifle bolt is coupled to the grip portion 3 by the link 17 which is secured at one end 18 to the bolt 5 and at its opposite end 19 to the grip portion 3. In addition, the trigger guard 8 is disconnected from the barrel portion 2 and is secured to the grip portion 3.
In operation, the rifle and modified rifle stock will appear in more or less conventional form as illustrated in Figure 2 with the bolt 5 in the closed position.
However, when it is desired to reciprocate the rifle bolt to eject a spent cartridge or to insert a new cartridge, it is now only necessary to lift outwardly and upwardly on the grip portion 3 and the link 17 will rotate the bolt 5 as well as lift the trigger guard 8 away from the barrel portion 2. When the grip portion 3 has been rotated sufficiently to clear. the butt portion 4, it may be pulled ba ckwardly to withdraw the bolt 5 and eject the spent cartridge or open the rifle breech to permit the insertion of another cartridge. The grip portion 3 is then pushed forwardly to close the rifle breech and the grip is thereafter rotated to bring the grip portion 3 into position between the butt portion 4 and barrel portion 2 and place the finger of the user, in the trigger guard 8, in position on the trigger 7.
What I claim as my invention is:
1. In a rifle having a barrel with a reciprocal bolt, a rifle stock separated into a barrel portion fixed to the said barrel, a butt portion fixed to the said barrel portion and spaced therefrom and a grip portion fitted removably between the said barrel portion and the said butt portion, a link fixed at one end to the said reciprocal bolt and at its opposite end to the said grip portion whereby movement of the said grip portion will move the bolt.
2. In a rifle having a barrel with a reciprocal bolt, a stock separated into a barrel portion secured to the said barrel, a butt portion and a grip portion, a rod secured at one end to the said butt portion and at its opposite end to 'the said barrel portion to space the said butt portion from the barrel portion, the said grip portion being fitted removably between the said butt portion and barrel portion and a link secured rigidly at one end to the said grip portion and at its opposite end to the said reciprocal bolt whereby movement of the said grip portion will move the said bolt.
