Definitions

  • This invention relates to improvements in gun sights, and more particularly to the rear sights of firearms for sporting purposes where a high degree of accuracy is desirable.
  • the invention relates more in detail to improvements in gun sights of the type in which the leaf or plate is mounted for adjustment with relation to the gun barrel, and has for its primary object to provide means for assuring a high degree of accuracy and a wide range of adjustment of the sight.
  • a further object of the invention is the provision of a gun sight in which the sight leaf carries a slide movable relative to a suitably *5 inclined or curved surface, whereby the angular position of the leaf with respect to the gun barrel is varied, the slide carrying a member adjustable relatively thereto and engaging the inclined or curved surface whereby a ner degree of accuracy of adjustment of the sight may be obtained.
  • FIG. l is a fragmentary side elevation of a gun barrel showing the improved sight applied thereto, portions of the gun sight being shown in section;
  • Fig. 2 is a transverse section on the line II-II of Fig. 1;
  • Fig. 3 is a view similar to Fig. l showing a modification of the invention.
  • Fig. 4 is a top plan view of the arrangement shown in Fig. 3.
  • the barrel of th-e gun is indicated at A, and carries a suitable support on which the sight leaf or plate l is pivotally mounted at 2.
  • a spring 3 coacts with one extremity of the leaf l, and normally tends to turn the latter in a direction to cause the terminal thereof carrying the sight member in the direction of the gun barrel A.
  • the leaf l is embraced by a slide 4 which is mounted for movement longitudinally thereof. and the portion of the gun barrel A underlying the leaf l is provided with an inclined surface 5.
  • a member 6 is mounted for adjustment in the slide 4, and the terminal thereof which is presented to the inclined face 5 is suitably shaped to reduce frictional resistance, so that during sliding movement of the member 4 along the leaf l the elevation of the sight or the angular position of the leaf with respect to the gun barrel is varied.
  • the member 6 is mounted for adjustment in a plane substantially at right angles to the axis of the leaf l and, in the example of the invention illustrated in the drawing, the member 6 is in the form of a screw which is thread- 60 ed in the slide 4 so that by turning the screw relative to the slide its position is varied as well as the position of the sight leaf l, the extremity 7 of the adjusting member 6 being retained at all times in engagement with the inclined surface 5 by the tension of the spring 3.
  • the inclined path or surface 5 is disposed along the longitudinal axis of the gun barrel, and in eecting major adjustments of the gun sight the slide 4 may be moved bodily together with the adjusting member 6 along the leaf l, while the finer and more accurate adjustment of the sight is effected by adjustment of the member 6 with relation to the slide 4.
  • the surfaces 5a are arranged at opposite sides of the aXis of the gun barrel and the sight leaf la is provided with a slide 4a.
  • the slide is provided with an adjusting member 6a constructed and arranged in accordance with the corresponding part 6 in the form of the invention illus- 85 trated in Figs. l and 2 and coacting in the same manner with the curved surfaces 5a to effect adjustment of the gun sight.
  • both ends of the slide 4a may be provided with screWs or adjusting members 6a 90 coacting with the respective curved surfaces 5a so as to avoid unnecessary lateral strains on the pivotal mounting of the sight.
  • a sight for firearms the combination of a barrel having a longitudinally running cam surface thereon, with a rigid sight-leaf rotatably mounted on the barrel, a spring turning said sight-leaf downwards, a slide guided on the sight-leaf and an adjustable member on the slide being held in contact with the cam surface through the action of said spring and being adapted to limit the movement of the leaf in the direction of the cam surface, said adjustable member being constituted by a set screw.
