ATTORNEYS nited States Patent 0 3,484,148 TEIESCQPIC SIGHT WITH SERPENTINE SPRING HVGT MEANS Hitoshi Gotoh, 566 ()haza Kamisuwa, Nagano-ken, Suwa-shi, Japan Filed Oct. 22, 1965, Set. No. 500,978 Int. Cl. F41g 1/38 US. Cl. 350-8 9 Claims ABSTRACT OF THE DISCLQSURE A telescopic sight construction providing positive resilient pivotal support in an inexpensive manner for the erection system and providing a direct reading range indicator for such system.
particularly, telescopes for use with rifles, are aware, the n designs for such constructions have become increasingly sophisticated in recent years. Problems of quality control have been replaced by problems of obtaining a truly satisfactory telescope from the preformers point of view without the expense of large sums. It is, accordingly, an object of the present invention to provide a rifie telescope of substantially reduced expense without related reduction in quality of performance.
In these circumstances, it has become increasingly important that improvements in rifle telescope constructions include reduction in complexity, both of use and manufacture. In accordance with the principles of the present invention, such savings have been incorporated, while at the same time operation of the rifle telescope has been improved.
In recent years, rifle telescopes have been constructed in which elevation and windage adjustments are accomplished by means of adjustment of the erector lens system, rather than by adjustment of the reticle per se. Although in earlier systems, the lens systems were rigidly mounted Within the main telescope barrel, it has been found that the adjustments of the erector lenses, en masse, are capable of providing an extremely desirable rifle telescope if the adjustment movement of the lens systems can be accomplished without weakening the systems ability to resist physical shock. In accordance with the principles of the present hivention, a novel and substantially improved, yet very inexpensive, pivot device is provided for securing one end of the erector lens-mounting barrel relative to the rifle telescope main tube. Additionally, the invention contemplates the provision of a novel, improved, mechanism for adjusting the other end of the pivoted erector tube, thereby providing a novel, simplified, rifle telescope adjustment mechanism.
Pursuant to the present invention, the rifle telescope erector lenses are mounted rigidly within a sub-barrel. This sub-barrel is pivotally mounted at its forward or rearward end, preferably at its rearward end, by means of a serpentine metallic spring element which encircles the erector barrel and varies between effective diameters substantially the same as the outside diameter of the erector barrel and diameter which is substantially the same as the internal diameter of the main barrel. This serpentine spring is held against longitudinal movement relative to the main barrel and the erector barrel. The opposite end of the erector tube is provided with a screw adjustment acting against a spring arranged to provide, with the ammunition of the type for which the telescope is designed, a direct reading adjustment by which the known range may be correleted with a reference point to adjust the rifle telescope instantly to the desired point of impact.
It is, accordingly, an object of the present invention to provide a new and improved system for mounting and adjusting a rifle telescope erector lens system.
Another object of the present invention is to provide a novel direct-reading sight adjustment.
Still a further object of the present invention is to provide a novel, universal pivot mount for erector barrels or the like.
A feature of the invention is the provision of a mounting and adjusting screw for the elevation adjustment of a sight which provides direct elevation readings in range units.
till a further feature of the invention is the provision of a pivot connection between a pair of concentric tubes which comprises a serpentine spring snugly co-operating with both tubes and axially fixed with respect to both.
Still other and further objects and features of the invention will at once become apparent to those skilled in the art from a consideration of the attached drawings and the following specification, wherein a preferred form of the invention is shown, by way of illustration only, and wherein:
FIGURE 1 is a side-elevational view in cross-section of a rifle teiescope constructed in accordance with the principles of the present invention;
FIGURE 2 is an enlarged side view of the erector tube suspension system shown in FIGURE 1 as viewed from an angle approximately 45 from the horizontal;
FIGURE 3 is a cross-sectional view taken along the line III-III of FIGURE 2; and
FIGURE 4 is a plan view, enlarged, of one embodiment of the adjusting screw employed for elevation adjustment in accordance with the principles of the present invention.
As shown on the drawings:
As may be seen from a consideration of the drawings, the rifle telescope of the present invention comprises a main tube 10 having an objective lens 11 and an eyepiece lens 12. Intermediate between the lenses 11 and 12 an erector lens system comprising a collector lens 13 and erector lenses 14 and I5 is rigidly mounted within an erector barrel 16. The erector barrel 16 is of a smaller diameter than the main tube and is mounted, in the embodiment illustrated, for pivotal movement about its rear, or eyepiece, end as indicated generally at 17. The other end of the erector barrel or tube is biased by means of a spring 19 into firm contact with an elevation adjustment screw 20 and a windage screw 21. A reticle, in any form, but conventionally in the form of a cross-hair, is provided at 18.
In operation, the rifle telescope of the present invention is rigidly secured, by securing the main tube 10, to a rifle or similar weapon in a rigid manner. This attachment may take any number of forms which comprise no part of the present invention, but which ordinarily consists of one or more rigid mounts arranged to attach the tube 10 in a position substantially parallel to the barrel of the rifle. With such attachment, the elevation screw 29 is positioned with its longitudinal axis in a generally vertical direction while the windage adjustment screw 21 is substantially horizontally disposed. With this arrangement the spring 19 lies substantially on the bisector of the angle between the screws 20 and 21 to provide a substantial .spring bias against both screws. In the embodiment illustrated, the pivot 17 comprises a serpentine spring 25 which is mounted in a circular channel 26 and is longitudinally secured relative to the tube 16 as well as the tube by means of a screw 27, which similarly lies on the bisector of the angle between screws and 21.
The pivot 17 comprising the spring 25, channel 26 and screw 27 provides an extremely strong and yet highly flexible mounting capable of providing universal pivotal motion over relatively narrow angles of deflection without introducing vibration or looseness. As may be seen in the drawing, the serpentine spring is of substantial width and has regularly alternating shoulder segment portions 250 and cradle segment portions 25b. The shoulder segment portions 25a are on a diameter equal to but normally slightly larger than the internal diameter of the main sight tube member 10 and thrust tightly frictionally toward the internal perimeter of the sight tube member. The cradle segment portions 2512 are on a diameter substantially smaller than the diameter about the segments 25a and arranged to thrust tightly frictionally toward the outside perimeter of the erector tube 16, being for this purpose normally on a slightly smaller diameter than the outside diameter of the channel 26. Accordingly, upon installation into the tube 10, a tight-oppositely thrusting friction fit of the segments 25a and 25b is provided which is permitted by the fact that the spring 25 is not completely circuitous but terminates at ends which together provide one of the erector tube cradling segments of the spring 250. The screw 27 passes through an aperture 28 in channel 26 and is threaded into tube 16. The head 27a of the screw is a tight fit in the aperture 10a. As a result of this arrangement, the tube 16 may rock about the head 27:; in the tube aperture 10a while at the same time it is maintained substantially exactly concentric with tube 10 by means of the serpentine spring 25. It may be observed that while it is not essential that the channel 26 be provided, it is preferred in order to insure accurate axial positioning of the spring 25 at all places about the periphery of the tube 16.
As above noted, simplification is an extremely important aspect of the present invention. It has been found, that when employing the relatively simple construction of this invention with rifles, that inexpensive rifles such as ordinarily chambered for the .22 caliber rifle bullet provide an important area of use. Such cartridges have a relatively curved or non-flat trajectory which is relatively constant in view of the accuracy of modern ballistic manufacture. Accordingly, the adjustment screw 20 is provided, in the present invention, with a thread providing a vertical elevational movement of the erector system throughout the normal effective range of such a Weapon, for example, 200 yards, in one full turn of the screw. In the arrangement illustrated, a bezel 22 is rotatably mounted about fixed mounting cap 24 and is adjustably secured thereto by means of a set screw 23. Accordingly, when the telescope is mounted upon the rifle, an initial setting of the telescope to zero in at 25 yards will subsequently provide automatic registry of the telescope for proper bullet impact at various ranges merely by directly setting the elevation screw 20 with the indicia marker 20a opposite the indicated range. It will be apparent, similarly, that an approximate range may be determined, after the rifle has been properly sighted in, as above observed, by observing the point of impact of the bullet following an adjustment for a predetermined estimated range.
In actual practice, it has been found that a .22 long rifle cartridge of standard manufacture will drop, due to the forces of gravity, a vertical distance of approximately eight inches over a travel of 100 yards. By considering the 25 yard point as a Zero point, with the rifle shooting at a slight angle upwardly so that the bore thereof coincides with the optical telescope axis at this point, it is possible to provide a total erector tube angle adjustment capable of providing a reticle movement of the said eight inches at yards. This movement may be accomplished by substantially less than one turn of the screw and, hence, satisfactorily accomplished in a direct reading manner, as illustrated. It will be understood that the ballistic direct-reading adjustment for the telescope may readily be employed with all manners of cartridges and this may simply be accomplished by substituting variously calibrated bezels 22. Manifestly, as higher powered cartridges are employed with a relatively flatter trajectory, a substantially greater yardage may be encompassed upon the periphery of the bezel 22 since one turn of the screw 20 will under these circumstances cover a range substantially greater than 100 or 200 yards. With this arrangement, the rifle telescope may be sold matched to a specific rifle or marketed with a Wide variety of bezels 22 for attachments to various rifles and specific ballistic loads.
It has been found, accordingly, that the construction of the present invention provides an essentially rigid, extremely inexpensive erector lens mounting system capable of simple adjustment in a substantially shock-proof manner. The simplicity of the system has lent itself to extremely inexpensive manufacture while providing a substantially improved rifle telescope.
I am, of course, aware that variations may be made in the structure above illustrated without departing from the scope of the novel concepts of the present invention. For example, the range markings may be fixed to the screw 20 and the pointer adjustably mounted on the tube 10. Alternatively, the movable ring may be adjustbly mounted on the screw 20. It will be further apparent that the shape of spring 19 may vary, that the tube 16 may be pivoted at the forward end and adjusted at the eyepiece end for elevation and windage, and/or that a spring portion 25b may be secured to the erector tube 16 by a second screw separate from a screw 27 securing portion 25a to tube 10 with or without channel 26. It is, accordingly, my intent that the scope of the invention be limited solely by that of the hereinafter appended claims.
