Abstract

A take-down rifle which permits easy removal and reassembly of the barrel to the receiver portion of the rifle and incorporating a system for effectively accommodating for wear in the mating parts thus providing for proper alignment between the rifle'"'"'s two main components. The system includes a barrel bracket secured to the forearm, an adjustable collar threaded on the receiver end of the barrel and in contact with the barrel bracket, and the bonding of the barrel to the forearm by means of a low durometer elastomeric adhesive. Adjustment for wear can be made by turning the adjusting collar in a direction to cause the barrel to move in a direction away from the barrel bracket which accommodates for any thread wear between the receiver and the barrel.

Claims

1. A take-down rifle having a stock and receiver secured together as a first unit and a forearm and barrel secured together as a second unit, with the receiver end of said barrel provided with means which engage with said receiver for securing said first and second units together as an assembled rifle, a reinforcing member mounted in said forearm, with said barrel being bonded to said forearm by means of an elastomeric adhesive, a barrel bracket mounted to the receiver end of said forearm and secured to said reinforcing member in said forearm with a portion of said bracket surrounding the receiver end of said barrel, and an adjusting collar positioned about the receiver end of said barrel and in contact with said barrel bracket and said barrel, whereby moving said adjusting collar in a direction toward said barrel bracket will cause said barrel to move in a direction away from said barrel bracket and said receiver end of said rifle to thereby compensate for wear in said means for securing said first and second units together as an assembled rifle.

2. The rifle of claim 1 wherein said elastomeric adhesive has a durometer reading ranging from about H_A 15-H_A 90 utilizing a type A durometer.

3. The rifle of claim 2 wherein said reinforcing member is metal.

4. The rifle of claim 3 wherein said forearm is made of a non-wood material.

5. The rifle of claim 4 wherein said forearm is made of a molded composite employing synthetic fibers.

6. The rifle of claim 5 wherein said elastomeric adhesive is a flexible elastomeric adhesive having a durometer reading ranging from about H_A 30-H_A 50 utilizing a type A durometer.

7. The rifle of claim 6 wherein said elastomeric adhesive includes those formed of silicones, polyurethanes, polysulfones and epoxy resins.

8. The rifle of claim 6 wherein said means which engage with said receiver for securing said first and second units together as an assembled rifle includes a threaded tenon on the receiver end of said barrel, a portion of which engages with a threaded opening in said receiver.

9. The rifle of claim 8 wherein said adjusting collar is positioned on said threaded tenon of said barrel.

10. The rifle of claim 9 wherein a receiver bracket is mounted to said barrel end of said stock and engages the barrel end of said receiver and wherein in an assembled rifle said receiver bracket and said barrel bracket are in contact.

11. The rifle of claim 10 wherein locking and alignment means are provided in said barrel bracket which engage with said receiver bracket.

12. The rifle of claim 11 wherein said stock is provided with a bedding block and wherein said receiver is secured to said bedding block.

13. The rifle of claim 12 wherein said receiver bracket is secured to said bedding block.
