Abstract

A high power bolt action rifle combined with a removable “back up” single shot barrel. The bolt action barrel would preferably be on top of the single shot barrel. This arrangement facilitates with the ease of converting it from hunting dangerous game (incorporating both barrels) to hunting non-dangerous game (removing lower single shot barrel). When hunting dangerous game with this rifle one receives the full benefit of a bolt action, and that of a double rifle. After the bolt action is fired the hunter can decide whether to immediately follow up the shot by firing the single shot barrel or work the bolt and load the bolt action and fire the bolt action barrel again.

Description

SPECIFICATION

This application is based on the provisional application SN 60/184325 filed on Feb. 23, 2000.[0001]

BACKGROUND OF THE INVENTION

The idea came to me after reading an article in “guns and Ammo” which debated a question pondered by many a sportsman. For dangerous game, which is better, a bolt action, or a double rifle?

The pros of the bolt action rifle are as follows; superior accuracy, long range capability, and a magazine capacity. The cons are unreliability (possibility of jamming), and the lack an immediate follow up shot. The pros of the double rifle include; immediate follow up shot, and reliability due to the simplicity of design. What the bolt action lacks, (reliability, immediate second shot) the double rifle has, and what the double lacks, long range accuracy and a magazine capacity the bolt action possesses. Therefore forcing the hunter to compromise on a sub-optimal.

Muller teaches a combination rifle/shotgun (DE920655, 1954) with a magazine for the shotgun barrel, and one heavy caliber and one light caliber rifle barrel without a magazine all barrels being permanently fixed. This arrangement would be heavy and would not meet the needs for hunting dangerous game because of the simple fact that it is based on the frame of a shotgun. As far as can be determined this gun has never been manufactured or used in practice.

The double barrel bolt action repeating rifle by Szescei (5440963, 1995) teaches a double barrel rifle with two magazines operated by a single action (bolt). This design would be heavy due to the two actions, two magazines and two permanent barrels and unreliable. The bolt action history of jamming which is not something a hunter would want who is hunting something that hunts back. As far as can be determined this gun has never been manufactured or used in practice.

The combination gun with repeater mechanism by Landaas (4679486, 1987) teaches a permanent double barrel rifle of varying calibers wherein each barrel has its own repeater mechanism. These barrels share a single trigger. The rifle has a selector switch that engages the desired firing mechanism to the single trigger. The firing mechanisms for this invention are automatic for the rifle and breech loading for the shotgun. Automatic weapons are seldom seen in a hunting environment due to their lack of precise accuracy and their tendency to jam. This gun incorporates a selector mechanism instead of a simpler double trigger which makes the gun more dependant on mechanisms and inherently less reliable. As far as can be determined this gun has never been manufactured or used in practice.

SUMMARY OF THE INVENTION

The invention would primarily be used by sportsmen in the pursuit of dangerous game. The rifle would incorporate the combination of a high power bolt action rifle with that of removable “back up” single shot barrel. This combination of barrels and actions could be arranged side by side or over under. Preferably and as shown in the drawings the frame of the rifle would be that of a bolt action. Underneath the bolt action barrel would rest another, single shot, barrel This arrangement facilitates with the ease of converting it from hunting dangerous game (both barrels) to hunting non-dangerous game(bolt action only). The lower barrel would have the capability to be removed (which would lessen the weight) when one is in the pursuit of large non-dangerous game. This barrel cold be a shotgun but most likely it would be a high powered rifle. Two triggers for each firing mechanism, a selection lever with one trigger or one complex trigger which would switch to the lower barrel after the bolt action has been fired and not re-chambered. This would most likely be more unreliable then two triggers, therefore probably obsolete. When hunting dangerous game with this rifle one receives the full benefit of a bolt action, and that of a double rifle. Hunters using this rifle have options which would aid in their survival when in the pursuit of dangerous game. Once the bolt action is fired the hunter can decide whether to immediately follow up the shot by firing the single shot barrel or work the bolt and load the bolt action and fire the bolt action barrel again. The advantages of the bolt action double rifle include long range accuracy and magazine capacity thanks to the bolt action., immediate follow up shot and the reliability equal to that of a double rifle thanks to the simple fact that there are two barrels and preferably two triggers.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1. The bolt action double rifle with the lower barrel breech in the locked position. [0008]
FIG. 2. The bolt action double rifle where the lower barrel breech is open in the loading position. [0009]
FIG. 3. View of the lower barrel and locking mechanism in the closed position [0010]
FIG. 4. View of lower barrel and locking mechanism in the loading position. [0011]
FIG. 5 Rifle shown with lower barrel removed. [0012]

DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1. The rifle shown with the lower [0013] single shot barrel 2 in the firing position. The lower barrel 2 is held in place by the locking mechanism 9. The locking mechanism 9 is operated by the lever 3. Firing mechanism 4 for the lower barrel 2 is engaged by trigger 8 or 10—preferably trigger 10. Bolt action firing mechanism 5 for upper barrel 1 is engaged by trigger 8 or 10—preferably trigger 8 for accuracy reasons. The upper barrel 1 and lower barrel 2 are attached by a hinge 7. The magazine 6 stores the extra cartridges for the bolt action firing mechanism 5 and upper barrel 1.
FIG. 2. Rifle shown with lower [0014] single shot barrel 2 in the loading position. The locking mechanism 9 is operated by pushing the lever 3 to the side causing the breech 12 to unlock and fall to the loading position.
FIG. 3. Possible locking apparatus for the lower barrel. [0015] Lower barrel 2 shown in the firing position with locking apparatus 9 exhibited in the closed or firing position. The locking apparatus 9 is operated by pushing the lever 3 to the side so that the shaft 24 which is connected to the lever 3 rotates. The rotation of the shaft 24 causes the joint 20 to rotate also. The rotation of the joint 20 pulls the locking shaft 22 back releasing the lower barrel.
FIG. 4. [0016] Locking apparatus 9 shown in the loading position with the breech 12 of the lower barrel 2 exposed. The locking shaft 22 is pulled back by the rotation of the joint 20 which is caused by the turning of the exposed lever 3.
FIG. 5. Rifle shown with lower “backup” [0017] barrel 2 removed.

Claims

I claim:

1. A rifle comprising: a bolt action firing mechanism and barrel combined with that of a removable single shot breech loading firing mechanism and barrel.
