(Cl. 33-56) This invention relates to improvements in tion in accordance with such indicia tg, correct sights for guns, rifles and firearms. points of elevation corresponding with predeter One of the objects of my invention is to pro mined ranges for a specific or particular type vide a sight for firearms which is characterized and character of ammunition or bullet. by marked simplicity of construction and opera Still another object of my invention is found in tion, and the elements of which possess novel fea the provision of means including a stud and a tures of construction, arrangement and provision tightening screw which may be secured to the which materially increase its effectiveness and range plate for definitely locating the range plate 10 use. on the sight. Among the novel features or elements of my sight is an improved sighting device the use of which will aiiord a more clear or sharply defined Still another object of my invention is to pro vide a novel elevation adjusting and locking han image of the object aimed at. Increased image ing the sight carrier and thereafter locking it in the desired adjusted range position; such adjust definition is attained by the use of a very thin ap erture disc which is so mounted in the bore of the sighting device as to be shielded from most of the interfering light rays. Peep-sights which are made from a single piece with a bore drilled in from each end to secure a thin separating ap ertured wall are not so commercially possible to ‘ manufacture as to produce the aperture of the desired precision as is possible to produce and se cure with an aperture disc made from a separate piece of very thin metal. Another object of my invention is to provide the sighting device with an interchangeable, re movably mounted, aperture disc so that discs having apertures of diiîerent diameters may be readily substituted one for the other. Another object of my invention resides in the provision of a firearm sight eye-piece the bore of which is provided with an oriñce which is com posed of a multiple of comparatively small planes each disposed angularly to the adjacent plane; the oriñce decreasing in diameter inwardly of ' the bore or which oriñce may be progressively de creased in diameter as by a series of circular steps decreasing in diameter progressively inwardly of the sight bore to thereby reduce to a minimum or 40 dissipate reflected interfering light rays to facil itate visibility and afford sharper definition of the image of the object viewed therethrough. A further object of the invention is found in the provision of a sight eye-piece having a re movably mounted aperture disc and a removably mounted aperture disc retainer, which retainer and aperture disc are adapted to be unscrewed from the eye-piece and screw-mounted into the peep-holder or block of a standard sight for use 50 as a small eye-piece to afford unobstructed vision, as for instance, on a hunting rifle. A still further object of the invention resides in the provision of a ñrearm sight having an in terchangeable plate with indicia thereon which permit the adjustment of the sight as to eleva . dle which serves as a handle for raising or lower ing and locking operations being performed by one hand of the operator. With the above and other objects in view, my invention consists in the novel combination, con struction and arrangement of the parts and members shown in preferred embodiment in the 20 attached drawing, described in the following spec ifications and particularly pointed out in the ap pended claims. Referring to the drawing: Fig. 1 is a side elevation of a gun sight embody ing my invention; Fig. 2 is a vertical section taken on line 2-2 of Fig. 1; Fig. 3 is a cross section taken on line 3_3 of Fig. 2 showing the operating and retaining mem ber for adjusting the sight as to elevation; 30 Fig. 4 is an enlarged vertical section taken on line 4-4 of Fig. 2 showing the improved sighting eye-piece, and Figs. 5 and 6 are enlarged perspective views of the aperture discs. As shown in the illustrations, the sight com prises an adapter block I0 of any suitable form which is adapted for attachment to the side of the firearm barrel II and on which block is supported the sight frame I2 by screws I3. The sight frame I2 is grooved, as at I4, to re ceive the vertical leg ISA of an L-shaped sight carrier I5. 'Ijhe horizontal portion or leg 15B of the sight 45 carrier is provided with a depressed channeled portion I5C for the slidably mounted peep-sight block I6, a lateral extension IGA of which is cen trally and longitudinally slotted, as at IEB. The peep-sight block I6 is slidably adjustable as to windage within the channel IBC and is adapted to be securely retained in adjusted position by a screw I'l mounted in the lateral portion ISB and extending for adjustable screw connection within 2 2,115,484 the slot IBB with the head thereof in engagement With the upper face of the extension IBA. gated slot 24A in the upper part of the range plate into threaded connection Within a small The block I6 is provided with a threaded bore IGC to receive a sighting device or peep-sight I8. range plate and positioned in a recess or hole in To facilitate and guide the operator in Wind age adjustment the extension IIìA may be pro vided with an in-dicator line which is adapted to register with suitable indications on the hori zontal portion |53. The sighting device or peep-sight I8 is formed with a comparatively enlarged eye-piece I8A hav ing an exteriorly threaded end connection I 8B into the slidable block I6 and is provided With a sight bore I8C which is enlarged inwardly, for substantially half of its length and threaded as at IBD to receive an aperture disc retainer I9. 'I‘he aperture disc retainer I9 is provided with a sight bore I9-^~ adapted to optically register with the bore I8C of the eye-piece IBA. The outer portion or orifice I9C of the bore I9A of the retainer I9 is formed with a multiple of small planes each disposed angularly to an adja cent plane, or progressively decreased in diameter as by a series of circular steps ISB which de 25 crease in diameter progressively inwardly of the sight bore I9A and which act to reduce or dissi pate to a minimum, by refraction, interfering light rays to thus afford a sharper or clearer defi 30 cylindrical stud 25A disposed on the back of the the leg I5A of the carrier I5. This range plate 24 is provided with indicia 24B which permits the adjustment of the sight, with reference to an indicator 26 (which, in the present instance, is a part of the frame I2) as to correct elevations corresponding with predetermined ranges for a specific or particular type and character of a bullet, the indicia preferably indicating the range of the targets in terms of yards. A specific range plate may be furnished for each specific type or character of ammunition, so that when 15 the ammunition is changed it is only necessary to interchange .the used range plate for a range plate calibrated for the changed ammunition. The precise position of the range plate may be corrected and adjusted by loosening the screw 25. 20 When the sight is attached to a riiie, the cor rect mounting or position of the peep-sight in relation to that rifle is zeroed once. This is done by adjusting the small zeroing screw 21. The interchangeable range plate is then adjusted to 25 zero position by loosening the screw 25 in the stud 25A, to permit vertical adjustment of the range plate. When the range plate for the par nition of the image of the viewed object. To further enhance the visibility and definition of the image of the sighted object, I provide an aperture disc 20 which is made from a very thin ticular ammunition has once been zeroed, the stud 25A is securely aflixed to the range plate by 30 tightening of the screw 25. To change one range material, as for instance steel of a thickness of .005 or .007 of an inch, and is provided with an the head ZIA is loosened and the sight staff or 35 aperture 2|)A in optical alignment or register with the axes of the sight bores I8C and ISA. The aperture disc 20 is removably mounted within the eye-piece I8 between the inner end of the retainer I9 and the shoulder formed at the 40 enlarged portion of the sight bore, or the inner end of the retainer I9 may be formed with a small annular groove to receive the aperture disc. Being removable, the aperture disc may be inter changed with any one of several other similar 45 aperture discs of different size apertures, thus providing a desirable andefûcient sight eye-piece. The exterior connection threads of the retainer I9 are such that the retainer I9 and aperture disc 20 may be readily removed from the eye 50 piece I8 and remounted in the sight block I6 for use as a small sighting eye-piece. To conveniently and quickly permit the verti cal adjustment of the sight as to elevation, the sight carrier I5 is slidably movable, with its ver 55 tical leg I5A within the stationary frame I2, by plate for another, when changing ammunition, carrier leg I5A removed from its support by up ward movement. The used range plate 24, screw 35 25, and stud 25A may then be removed as a unit and replaced by a similar unit plate which has previously been corrected for the ammunition then to be used. ‘The removed range plate can thereafter always be properly reinserted into pre 40 determined zeroed position, for use with the par ticular ammunition for which it was previously calibrated, by replacing with its attached stud in the hole provided for it in the vertical leg I5A of the carrier. It is obvious that various changes or modifica tions may be made in the details of construction or arrangement in the sight as here shown in preferred embodiment without departing from the spirit of the invention as defined in the ap pended claims.
