Primary Examiner-Louis R. Prince Assistant ExaminerRichard R. Stearns Attorney, Agent, or Firm-l-larness, Dickey & Pierce [5 7] ABSTRACT A gun sight mounting arrangement for a firearm comprising a mounting member, means defining first cooperable tenon and tenon receiving recessed areas on the mounting member and the firearm, a sighting member adapted to be operatively supported on the mounting member, means defining second cooperable tenon and tenon receiving recessed areas on the mounting member and the sighting member, first adjustment means for selectively vertically adjusting the sighting member relative to the firearm, and second adjustment means including the first and second tenons and tenon receiving recessed areas for selectively transversely adjusting the sighting member relative to the firearm.

1 Claim, 5 Drawing Figures GUN SIGHT BACKGROUND OF THE INVENTION It has heretofore been the practice in securing or attaching firearm sights by means of complementary shaped dove tail slots and tenons, to dimension the respective slots and tenons such that it was necessary to forcefully drive the tenon into the associated dove tail slot by means of hammering, or through the use of expensive sight mounting presses and the like. This practice has been objectionable from the standpoint of the expenses and time involved in purchasing and utilizing such mounting presses, but more importantly, from the standpoint that frequently both the firearm and the gun sight being mounted thereon have been marred, scratched or are otherwise damaged, thus rendering the sights and firearms aesthetically unattractive and subject to the deleterious affects of moisture, dirt, etc.

The present invention is intended to overcome the aforementioned objectionable characteristics of prior known dove tail mounting arrangements through the provision of a novel gun sight design wherein the dove tail tenon on the gun sight mounting member is dimensioned slightly undersize with respect to the dove tail slot on the firearm inwhich said tenon is to be operatively disposed, whereby the mounting member may be easily inserted or slid into the slot without any need for hammering the member into place, and without requiring the use of expensive sight mounting presses as have been employed in the past. The gun sight of the present invention is provided with a locking arrangement whereby after the dove tail tenon has been inserted into the mounting slot on the firearm, the mounting member may be conveniently fixedly secured or locked in place through simple manipulation of a screwdriverlike tool or the like. Together with rendering the gun sight of the present invention extremely convenient to mount and dismount or remove, the aforementioned arrangement permits extremely simple windage adjustment which, in itself, permits rapid"sighting in and provides means cooperable with the associated support means for the sighting element to provide for a double windage adjustment. Accordingly, the gun sight of the present invention may be rapidly and effortlessly adjusted, and also may be installed in an extremely simply and convenient manner, as hereafter will be described in detail.

SUMMARY OF THE INVENTION This invention relates generally to firearm sights and, more particularly, to a new and improved gun sight which minimizes to the extreme, the time and effort required for mounting, dismounting and sighting adjustment thereof. Y

It is accordingly a general object of the present invention to provide a new and improved gun sight.

It is a more particular object of the present invention to provide a new and improved gun sight which is extremely simple to mount and convenient to adjust.

It is another object of the present invention to provide a new and improved gun sight of the above described character which comprises minimum number of component parts.

It is still another object of the present invention which provides for convenient interchanging of sight elements so as to provide for universality of application.

It is a further object of the present invention to provide a new and improved firearm sight, as above described, which is of a relatively simple design and is therefore economical to manufacture.

Other objects and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the'accompanying drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now in detail to the drawing, a gun sight 10, in accordance with an exemplary embodiment of the present invention, is shown in operative association with a conventional firearm 12. The firearm 12 includes a barrel or receiver section 14 upon which the gun sight 10 is adapted to be mounted and which is formed with a transversely extending dove tail slot or recessed area 16, defined by downwardly diverging, transversely extending forward and rearward surfaces 18 and 20, respectively. Generally speaking, the gun sight 10 of the present invention comprises an elongated longitudinal extending mounting member, generally designated by the numeral 22, which comprises a forward end section 24, an intermediate section 26, and an enlarged thickness rearward section 28 adapted for operatively supporting a conventional sighting member or element 30.

In accordance with the principals of the present invention, the mounting member 22, and in particular, the forward end section 24 thereof, is formed with a downwardly projecting dove tail shaped tenon, generally designated by the numeral 32, which is adapted to be slidably received within the dove tail slot 16 formed in the firearm 12. The tenon 32 is formed with forward and rearward downwardly diverging, transversely extending inclined surfaces 34 and 36, respectively, which are of a complimentary orientation with respect to the surfaces 18 and 20 and are dimensioned such that the tenon 32 may be freely slidably inserted into the slot 16 without the use of or need for hammering or otherwise forecefully urging the mounting member 22 into the operative position illustrated, for example, in FIGS. 1 and 2.

In order to positively fixedly secure or retain the mounting member 22 within the dove tailed slot 16 at some preselected transverse position therein, the gun sight 10 is provided with a gib locking arrangement, generally designated by the numeral 38. The arrangement 38 comprises a locking screw 40 having an enlarged head section 42 and an externally threaded shank section 44 which is adapted to extend axially downwardly within a suitable countersunk bore 46 that is formed directly rearwardly of the transversely extending inclined surface 36, as best seen in FIGS. 2 and 3. the shank section 44 of the screw 40 extends through the bore 46 into threaded engagement with a generally cylindrical shaped wedge block or gib element 48 having central threaded bore 50 adapted for reception of the screw 40. The gib element 48 is formed with an inclined face or facet 52 which is adapted for engagement with the inclined surface 20 of the dove tail slot 16. More particularly, when the screw 40 is threaded into the gib element 48, the latter is drawn upwardly within the lower end of the bore 46, whereby the inclined face 52 tightly engages the inclined surface 20, whereby to fixedly secure the dove tail tenon 32 within the dove tail slot 16, once the mounting member 22 has been located in a preselected transverse position with respect to the firearm 12.

The sighting member 30 comprises an upwardly projecting, transversely extending sighting blade section 54 which is formed with a central sighting notch 56 adapted for sighting alignment with the associated front sight (not shown) on the firearm 12. As will be appreciated by those skilled in the art, the particular size and configuration of the notch 56 may be designed and selected by the firearm operator so as to best adapt the firearm 12 for its particular intended use, i.e., hunting, target shooting, etc. The lower end of the sighting member 30 is formed with an integral dove tail tenon 58 which is defined by downwardly diverging transversely extending

inclined surfaces

60 and 62 and is adapted for sliding engagement or insertion into a complementary dove tail shaped slot or recessed area 64 formed in the upper surface of the rearward end section 28 of the mounting member 22 and defined by downwardly diverging transversely extending inclined surfaces 66 and 68.

In order to lockingly secure the sighting member 30 at some preselected adjusted transverse position with respect to the mounting member 22, the gun sight of the present invention is provided with a second gib locking arrangement, generally designated by the numeral 70. The arrangement 70 comprises a locking screw 72 having a head section 74 and an externally threaded shank section 76 which extends downwardly through and is threadably engageable with a threaded bore 78 formed in the mounting member 22 at a position directly forwardly of the dove tail slot 64. The upper end of the bore 78 is formed with a counterbore 80 within which a wedge block or gib element 82 is mounted. the element 82 is formed with a central aperture 84 through which the shank section 76 of the locking screw 72 extends, the head section 74 of the screw 72 being nestingly received within a suitable counterbore 86 formed at the upper end of the aperture 84. the gib element 82 is preferably of a generally cylindrical configuration and is formed with an inclined face or facet 88 adapted for engagement with the inclined surface 60 of the dove tail tenon 58, whereby upon threaded advancement of the locking screw 72 within the bore 78, the gib element 82 may be forced downwardly. whereby the face 88 positively engages the surface 60 to rigidly connect the sighting member 30 at some preselected transverse position with respect to the mounting member 22.

In order to provide for elevational adjustment of the sighting member 30, the gun sight 10 of the present invention is provided with a screw element 90 which comprises an externally threaded body 92 adapted for threaded engagement with a generally vertically arranged internally threaded bore 94 formed in the rearward section 28 of the mounting member 22 directly forwardly of the bore 78. the screw element 90 is formed with a lower end section 96 adapted for engagement with an upper surface 98 of the barrel or receiver section 14, whereupon suitable rotation of the screw element 90 in either a clockwise or counterclockwise direction will effect raising or lowering of the rearward end section 28 of the mounting member 22, and hence will effect raising or lowering of the sighting member 30 until the desired elevational adjustment is achieved.

In operation of the gun sight 10 of the present invention, it will be seen that elevational adjustments may be made through proper rotation of the screw element 90, as above described, and that windage adjustment may be achieved through proper loosening or release of the gib locking arrangement 70, whereby the sighting member 30 may be transversely adjusted with respect to the mounting member 22, and that the locking screw 72 may be subsequently tightened when the desired windage adjustment has been accomplished. It will be noted that a particular feature of the present invention resides in the fact that windage adjustments may not only be accomplished in the aforesaid manner, but also by release of the gib locking arrangement 38 and transverse adjustment of the mounting member 22 within the dove tail slot 16 on the firearm 12. Thus, the present invention provides for a double windage adjustment. It will be appreciated, of course, that at such time as it is desired to remove, replace, or otherwise interchange the sighting member 30 with a different sighting member having a different shaped sighting notch 56, the locking arrangement may be released in the above described manner to effect such interchanging. That is, the sighting member 30, upon loosening the locking screw 72, may be slipped from the slot 64 and another type of sighting member may be inserted in its place and be secured within the slot 64 upon proper tightening of the locking screw 72.

It will be seen from the foregoing that the present invention provides a novel gun sight arrangement which may be mounted and dismounted from a firearm in an extremely rapid and convenient manner, and without the need for any expensive sight mounting presses, whereby to positively assure against marring, scratching or otherwise damaging the sight or the firearm with which it si associated. As described above, a further feature of the present invention will be seen in the fact that the gun sight 10 is adapted for rapid interchanging of sighting members and may be rapidly adjusted, boty for elevation and windage corrections. Still another feature of the present invention will be seen in the fact that the gun sight 10 is of an extremely simple design so that it may be economically manufactured and will have a long and effective operational life.

While it will be apparent that the preferred embodiment illustrated herein is well calculated to fulfill the objects above stated, it will be appreciated that the present invention is susceptible to modification, variation and change without departing from the scope of the invention.
