SOL DUBIN BY WWW ATTORNEY United States Patent 3,208,351 MICROMETER REST FOR FIELD GUN Sol Dubin, Rockville Centre, N.Y. (217 Merrick Road, Amityville, N.Y.) Filed Feb. 18, 1964, Ser. No. 345,734 6 Claims. (or, 89-40) The present invention concerns gun rests and, in particular, micrometer adjustable barrel and butt positioning means.
Many devices have been provided for positioning guns to provide stable and accurate aiming means. In the past these devices have been cumbersome, complex and expensive. For these reasons such devices have been unsuitable for use 'by amateur gun men and particularly unsuitable for field and portable use.
The present invention concerns methods of and means for providing simple, inexpensive yet highly precise means for positioning a gun. The present invention also provides a device which is light to carry and easy and quick to adjust in the field. According to the present invention a simple hand wheel operated elevator screw is provided for the barrel of the gun and a similarly simple and light but effective screw operated means for the butt of the gun.
Accordingly one object of the present invention is to provide simple, accurate, light weight and inexpensive gun positioning means for a field gun.
Another object is to provide gun positioning means which is easy to attach to a gun.
Still another object is to provide gun positioning means which is simple and precisely positionable but which can be easily and quickly adjusted.
A further object is to provide an effective but very inexpensive gun positioning device which readily adapts to uneven ground conditions and which while maintaining a steady position of the gun for aiming and firing at the same time has a certain amount of give to cushion recoil forces.
These and other objects will be apparent from the detailed description of the invention given in connection with the various figures of the drawing.
In the drawing:
FIGURE 1 is an assembly view of the positioner in accordance with the present invention attached to a typical gun.
FIGURE 2 is a side elevation view of one portion of the present invention.
FIGURE 3 is a cross-sectional view of the portion of the present invention shown in FIG. 2.
FIGURE 4 is a side view partly cut-away of the second portion of the present invention.
FIG. 1 shows the front and rear gun positioner of the present invention attached to a typical gun. The front or barrel portion of the positioner includes a three legged stand 1, a hand-wheel adjusting device 2 operating on a screw 3 which is connected to barrel mount 5 by means of a ball-nut mounted connector 4. The rear or butt portion of the positioner includes shank portion 7, butt mount 6, screw adjusting means 8 and end cap 9. All of these components will be described in more detail below in connection with the other figures of the drawing.
FIG. 2 is a side elevation view of the barrel positioning portion of the present invention as shown in FIG. 1 and briefly described above. Legs 1 form a tripod mounting the hand-wheel 2 which carries and positions screw 3. The connector 4 forms a split clamp which may be tightened around ball-nut 17 by means of screw 16 forming an extension of rod 13 turnable by means of pin handle 14. Final clamping of ball-nut 17 to screw 3 is accomplished by clamping nut 15. Although clamp 4 may be tightened around ball-nut 17, it should be done only to a 3,208,351 Patented Sept. 28, 1965 degree suflicient to stabilize the gun butt which will allow the joint to give under the recoil forces set up on firing the gun.
FIG. 3 shows further details by means of cross-sectional viewing of the barrel portion of FIG. 2. This view shows the internal threads 10 in hand-wheel 2 for mating with screw 3. The thread carrying portion of hand-wheel 2 passes through hole 22 at the upper end of tripod 1 and is prevented from dropping out by means of split spring washer 11. At the upper end of screw 3 connector 4 clamps around ball-nut 17 locked on the end of screw 3 at a reduced section 12 by means of nut 15 and is tightened by turning screw 16 as described above. Connector 4 is adapted to be secured to barrel mount 5 by means of non-removable screws 18 and 19 which screw into threaded holes 20 and 21. Barrel mount 5 is provided with holes 27 and 28 adapted to receive screws for holding mount 5 securely on a gun barrel.
FIG. 4 shows rear elevator 7 which is bent and carries non-removable screws 23 and 24 for mounting the elevator on butt mount 6 tapped at 25 and 26. Mount 6 carries screw holes 29 and 30 to permit it to be screwed to the gun butt. Elevator 7 includes a threaded extension 31 adapted to receive the internally threaded tube 8 having an extended cavity 32 permitting lengthening or shortening the elevator by turning tube 8 on extension 31. The end of extension 31 is closed by cap 9 threaded into extension '31 at 33. The end of cap 9 is knurled at 34 for gripping to turn tube 8 in making adjustments and rounded end 35 adapted to rest on the ground when the butt mount is being used to position the gun.
It will thus be seen that the micrometer gun positioning device of the present invention is simple but effective. The ball-nut which forms the link between the barrel tripod and the gun barrel permits setting the tripod at any angular position with respect to the barrel. This has been found to be extremely useful on uneven or hilly ground. In actual use the clamp is tightened until the gun is supported firmly but since the gun is not rigidly connected to the tripod, any excessive recoil forces upon firing will serve merely to change the angular position of the gun with respect to the tripod. The ball-nut (a nut with a partial spherical surface) is a simple, inexpensive and effective device for providing a swivel joint with adjustable tension, etc. as described above.
While only one form of the present invention has been shown and described, many modifications will be apparent to those skilled in the art and within the spirit and scope of the invention as set forth in particular in the appended claims.
What is claimed is:
1. A field gun positioning device including in combination a gun barrel elevator including: a tripod, a threaded vertical shaft, a hand-wheel including an in ternally threaded passage therethrough for elevating said shaft through said tripod, a ball-nut secured to the upper end of said shaft, a clamp for gripping said ball-nut adapted to form a non-rigid coupling therewith, means for securing said clamp to said gun barrel; and a butt positioner including a linearly extensible butt rest, and means for securing said butt rest to the butt of said gun at a predetermined angle.
2. A field gun positioning device as set forth in claim 1 and including means for setting the pressure of said clamp against said ball-nut.
