Definitions

  • the above-mentioned solid bead is omitted and a black mark painted on the inclined white surface. This avoids the danger of the pistol catching when being drawn but in the event of front lighting the coloured mark was scarcely distinguishable and under other lighting conditions the bead appeared absolutely grey and blurred.
  • a fiat triangular structure was placed upright on the inclined white surface and a backsight leaf with triangular, rectangular or even semicircular notch was used. In this case the bead, when fitted on a pistol, was liable to catch when drawing quickly. Furthermore the former difliculties when sighting could also not be overcome.
  • the invention has for its object to make the front and back sights appear light against dark objects and dark against light objects.
  • the proposal according to the invention consists in that, in a sighting device for firearms with marks applied on the front and back sights, the mark 3,192,632 Patented July 6, 1965 ice on the front sight or bead be substantially a circular surface having a diameter about the width of the front sight or head and that the upper boundary line of the mark shall lie on the upper boundary line of the bead visible when aiming while the lower part of the mark is rounded, further that the mark be in a different plane to the other surface portions on the side of the front sight facing the marksman, and that the back sight be provided with a strip or band-like mark extending vertically in the area of vision of the marksman up to a notch aperture, whereby the strip or band-like mark shall also lie in a different plane to the surface portions on the side of the back sight facing the marksman, and finally that the marks on the front and back sights be coloured to stand out in contrast from the above-mentioned surface portions.
  • the parts of the bead or front sight on the two sides of the mark be located in shadow so that they appear in dark contrast to the mark.
  • This effect is attained by arranging on the two sides of the mark, band or strip-like surfaces bordering the mark tangentially in the range of vision of the marksman and extending at an incline opposite to the incline of the portion of the front sight provided with the mark, these bands or strips being located behind the mark in the firing direction.
  • the connecting line between the two upper edges of the two band or strip-like surfaces contacts the mark tangentially in the form of a circular surface.
  • a mark of another areal shape then extends up to the above-mentioned imaginary connecting line which coincides with the upper visible boundary line of the front sight.
  • the back sight coordinated to the bead or front sight has a surface inclining upwards in forward direction and extending up to the lower edge of the sight leaf or plate leaning towards the marksman and provided with a notch or sight aperture and immediately below the aperture in the forwardly ascending surface the band or strip-like mark is provided which clearly stands out in colour against the colour of the material of the back sight. So that the contour of the back sight and especially of the mark arranged below the aperture or notch remain sharply visible under incident light, the sight plate is inclined towards the marksman in the manner mentioned above.
  • the notch or aperture of the back sight should not be absolutely semicircular but, commencing at the top, the sides of the aperture should first extend vertically downwards to about 25% of the depth and then be so rounded that a horizontal middle portion is obtained, whereby the bottom horizontally extending line of the back sight aperture is of a width corresponding to that which the bead or front sight appears to be when aiming.
  • the marks may consist of luminous paints or other substances appearing white in daylight and luminous at night.
  • the luminous colours of the bead and the back sights are preferably so adapted to each other that the marks appear to be of equal luminous strength to the eye of the marksman.
  • the marks on the front and back sights are of such Width that they appear to be of the same width to the marksman when aiming, whereby the relation of the actual widths is calculated according to the formula E being the distance between the eye and the back sight, L the length of the line of sight, and M the reduction factor by which the diameter of the mark on the bead must be enlarged in order to obtain the necessary width of the strip or band on the back sight.
  • the upper boundary line of the bead and the sight plate should coincide when the two coloured marks contact.
  • the marks on the front and back sights are likewise possible for the marks on the front and back sights to consist of black surfaces on a light ground. So that the marks on the front and back sights appear in sharp contour and not blurred or even grey under all lighting conditions, it is proposed according to a further feature of the invention that the mark appearing black or blackish on the bead consist of a bore or a similar deep recess with sharp boundary edges.
  • the strip or band-like mark appearing dark or black on the back sight can be formed by an incision with sharp edges in the forwardly sloping surface of the back sight, whereby, differing from the back sight illustrated in FIGS. 3 to 6, the ascending surface of the embodiment illustrated in FIGS.
  • the aperture of the back sight not to be absolutely semicircular but the sides of the aperture, commencing at the top should first extend vertically downwards to about 25% of the depth and are then so rounded that a horizontal middle portion is obtained and the bottom horizontal line of the back sight aperture is of such length that it appears equal to the width of the front sight when aiming.
  • the bores, incisions or other recesses with sharp edged or contrasting boundary surfaces can, in order to form the sighting marks, be provided with other means for preventing the light from penetrating into the bores, incisions 01' the like.
  • the bore or incision can be undercut so that the inner walls of the bore or incision are always lo cated in the shadow.
  • the bores and incisions should always be of sufficient depth to produce ample shade and contrast effect.
  • the walls of the bore or incision can be provided with a light absorbent surface for which purpose the surfaces may be roughened so as to avoid mirror effects or reflections of light. They may, however, also be provided with a suitable dark light-absorbent coating.
  • the front and rear sights appear light against dark objects and dark against light objects and the sights appear white or black as required.
  • the sighting device according to the invention is so designed that the eye adjusts itself according to the white or black of the sight according to the lighting and according to the colour of the target without any effort and without the marksman being conscious of selection. All these conditions being met, unavoidable angular shapes of the bead and the sighting leaf are screened by protecting devices so that the pistol cannot catch when being drawn.
  • FIG. 1 is a perspective View of the front sight of a firearm
  • FIG. 2 shows the front sight or bead according to FIG. 1 in the line of vision of the marksman
  • FIG. 3 is a perspective View of the back sight complementing the bead or front sight illustrated in FIG. 1, and
  • FIG. 4 a section through the back sight shown in FIG. 3;
  • FIG. 5 shows a bead or front sight according to FIG. 1 and a rear sight according to FIG. 3, both appearing black under strong front lighting;
  • FIG. 6 shows the same sighting device with a white spot mark on the front sight and a white band or strip mark on the back sight under lighting from the rear;
  • FIG. 7 is a perspective view of the front sight for a firearm with marking in the form of a circular area pro quizzed by a bore;
  • FIG. 8 is a perspective view of a back sight for use with the front sight of FIG. 7;
  • FIG. 9 is a section taken in a vertical plane passing through the centre of the back sight according to FIG. 8, and
  • FIG. 10 shows the black marks produced by the bore and incision in the case of the sighting device with front sight or head and back sight according to FIGS. 7 and 8 respectively.
  • the downwardly sloping surface 10 on a rearwardly extending projection of the body of the head or front sight 11 facing the marksman is provided with a white mark 12 in the form of a circular spot or surface, whereby the mark 12 consists of a luminous paint which appears white in daylight and luminous in the dark.
  • This mark may be composed of white paint embedded in a recess corresponding to the shape of the mark. It may also consist of a source of light which appears light or white in daylight and emits light in twilight or darkness.
  • the body of the front sight or bead 11 is considerably wider than the mark applied in its middle portion, the mark being about /3 the width of the head.
  • the upper boundary line of the mark or in this case the vertex of the mark is located on the upper horizontal boundary line 13 of the body or bead 11 visible when aiming.
  • the strips or bands 15 and 16 of the bead are shaded from the light and appear dark or in contrast to the mark 12 because they are screened against the incidence of light.
  • These strips or hands 15 and 16 of the head on the right and left of the mark 12 are inclined in the opposite direction to the inclination of the rear sighting surface 10 provided with the mark 12 and as a result .are in a different plane to the flat surface 10 of the projection bearing the mark 11.
  • the connecting line 13 of the upper boundaries of the strips or bands 15 and 16, which at the same time forms the upper line of the bead or front sight when aiming, is tangential to the mark 12. It is to be noted that the mark 10 is tangent to the horizontal line 13 and is tangent to the side edges of the projection bearing the mark 10.
  • FIGS. 3 and 4 show a rear sight block 18 with rear sighting surface 19 sloping upwards towards the front and extending up to the lower edge of the sight leaf 20 with the notch or sight aperture 21.
  • the elongated rectangular mark 22 is provided on the forwardly ascending surface 19. It is also possible to dispense with the surf-ace 19 providing the strip or band 22 remains in the position shown.
  • the sight leaf 20 leans over in the direction towards the marksman, so that the part facing the eye of the marksman is in shadow and appears dark, as can clearly be seen from FIG. 3 (23).
  • FIG. shows the sighting device under strong front lighting; it then appears entirely black and the colour marks cannot be seen because aim is normally taken with black bead and black back sight.
  • the marks 12 and 22 become light and it is not possible for the mark 12 to appear blurred, it being laterally bordered by the black or dark strips or bands 15 and 16.
  • the optical effect is enhanced by the angular position of the lower portion of the rear sight.
  • the upper part with the sighting aperture remains dark while the lower part with the strip mark remains light. For aiming it is only necessary to bring the point or circular spot 12 into alignment with the strip or band mark 22.
  • FIG. 6, like FIG. 5, shows the upper portion of the rear sight as being of a depth equal to the width of the white strip or band and as the band corresponds exactly to the diameter of the white spot on the front sight when aiming, the white spot will fit in the notch in the direction of height so that it is just in contact with the strip without departing from the position of aligned bead. It is immaterial whether the aiming is effected with white or black, the aiming position is the same in both cases.
  • a thickness of 2.8 to 3.2 is found particularly advantageous for the bead, depending upon the kind of weapon and the length of barrel.
  • the notch should not, however, be too wide. Although when rapid firing the bead can more easily be found through a wide notch, yet it is more difficult to keep in the middle thereof. Consequently the back sight notch or aperture should not be more than twice the Width of the bead. A ratio of 3:2 has been found particularly advantageous. A too deep notch is disadvantageous because it tires the eye without offering any advantages.
  • FIGS. 5 and 6 also show the combination of a semicircular and rectangular back sight aperture and that in addition the sides 21 of the aperture commencing at the top extend downwards a distance equal to about 25% of the depth and are then rounded so that the bottom of the notch or aperture is fiat, the horizontal portion of the notch being of a length which appears when aiming to be about equal to the width of the bead.
  • the angular sight leaf is accommodated in a block with rounded corners.
  • FIG. 7 shows a front sight body or bead 24 of modified construction having a rear sighting surface 25 ascending at an incline and producing a light effect to the eye and in which a circular bore or recess 26 is provided extending parallel to the axis of the firearm barrel and constituting a circular mark which always appears black or very dark.
  • This bore or recess 26 is deeper than shown in the drawing to ensure that a black or dark mark is produced and prevent light from penetrating the bore and reaching the bottom thereof. In this case the mark lies in a different plane to the fiat portion 25 of the bead.
  • the upwardly ascending rear sighting surface 27 of the back sight block 28 is provided with an incision or slot 29 which produces a black or blackish area constituting the aiming mark.
  • the upper horizontal boundary edge 30 of the incision or slot extends right or nearly up to the lower edge of the substantially semicircular back sight notch or aperture 31.
  • the surface 27 sloping upwards in forward direction extends at the same angle of inclination up to the upper edge 32 of the back Sight.
  • FIG. 10 shows the effect obtained with the bore 26 and the incision or slot 29 when aiming, because the marks always appear black or dark and stand out in strong contrast from the surrounding surfaces.
  • the light surfaces 25 of the bead and 27 of the back sight are particularly advantageous. As the surfaces are relatively large, it is advantageous to use only a slightly luminous paint which is not likely to dazzle yet enables the contrast between the marks in the form of a bore or an incision to be clearly recognizable.
