Application February 4, 1946, Serial No. 645,265

8 Claims. (Cl. 33-47) This invention relates to gun sights designed primarily for use on rifles, Shotguns, etc.

It is a fact Well known to marksmen that gun sights heretofore used do not enable the marksman to `draw a bead on the target as quickly and accurately as desired inasmuch as the cooperating front and rear sights generally have been so constructed that the user must first bring them carefully into line with the target, Some forms of sights are especially diflicult to use in the dark and all of them as far as I am aware, have required a steady and careful movement of the sight until such time as they can be brought into line with the target.

An object of the present invention is to provide a gun sight the front and back members of which are so constructed as to enable the user to quickly draw a bead on the target without the usual diiliculty in shifting the front end of the barrel until such time as the front sight is brought into line with the target and the rear sight.

It is a further object of the present invention to provide front and rear sights which cooperate to instantly form a peep-hole in line with the target, the formation of this peep-hole indicating to the user that an accurate bead on the target has been drawn.

It is another object of the invention to provide gun sights the members of which are reversble whereby luminous portions can be brought into view of the user to define the peep-hole which is created when the sights are brought in line with the target, thereby rendering the sights particularly desirable for use in the dark.

A still further object is to provide a gun sight one of the members of which has beads of contrasting colors whereby proper location of one of the members of the sight relative to the other is expedited, the contrasting shades of the exposed surfaces of the gun sight serving to aid the user in drawing a bead on the target whether the target is of a light or a dark color.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a side elevation of a portion of a rifle equipped with the present improvement, the gun sight being shown in vertical longitudinal section and positioned for daytime use.

Figure 2 is a top plan view of the structure shown in Figure 1.

Figure 3 is a section on line 3-3 Figure 1.

Figure 4 is a section on line 4-4 Figure 1.

Figure 5 is an elevation of the front sight, illustrating that face thereof opposite the one shown in Figure 3.

Figure 6 is an elevation of the cooperating beads as viewed by the user of the gun, the sights being positioned as shown in Figures 1 and 2 for daytime use.

Figure 7 is an enlarged section through one of the beads.

Referring to the figures by characters of relerence S designates a portion of the stock of a riile or the like and B designates a portion of the barrel.

The barrel is equipped with a rear sight member R and a front sight member F which can be attached to the barrel in any desired manner.

The rear sight member includes a supporting member I which can be attached to the barrel B in any suitable manner and mounted on this member is the base 2 of the rear sight. This base is mounted for lateral swinging movement on a pivot element 3 and it is provided at one end with suitable means whereby said base can be swung laterally in either direction on the member I. This means can include a spring tongue 5 extending from the base 2 and frictionally engaging the top surface of the member I. Notches 6 and 'I can be formed in the supporting member I and tongue 5 is adapted to snap into either of them. As they are diametrically opposed, the tongue will. cooperate with them to hold the base 2 in either of two oppositely extended positions.

Mounted on the base 2 at that end thereof remote from the tongue 5 are spaced arms 8 the upper ends of which are extended toward each other to form fingers 9. Cylindrical beads IU are carried by the lingers and are parallel with each other and with the longitudinal center of the barrel B. As shown particularly in Figure 7 each of these beads can have screw plugs II extended into the ends thereof from heads I2 and I3 which preferably are coaxial and circular. It is preferred to make the exposed fiat surface of the head I2 with a luminous coating of any suitable kind whereas the exposed circular surface of the head I3 can be white or non-luminous if desired. The two beads are accurately and similarly positioned relative to the axis of the bore of the gun barrel and the space between the beads provides a narrow clearance through which the target can be viewed by the used. When the rear sight is positioned as shown in Figures 1, 2 and 4 the white heads I3 are exposed to the View of the user but obviously by reversing the position of the rear sight the luminous heads I2 will be brought into view.

The front sight, like the rear sight, has a suitable supporting member I4 carried by the barrel and pivotally mounted on this member is the base l5 of the front sight. The parts are connected by a pivot element I6. Extending upwardly from one end of the base I5 is a frame Il extending transversely and provided with an upwardly extending arm I8 positioned beneath a depending arm I8. These arms, I8 and I9 carry lower and upper beads and 2l respectively which are parallel to each other and to the longitudinal axis of the bore of the riile. Both oi' the beads are equipped with caps which can be mounted as shown in Figure 7 but the front sight diiers from the rear sight in that bead 20 has a luminous cap 22 at one end and a white cap 23 at its other end while bead 2| has a luminous cap 24 at one end and a dark cap 25 at its other end. For daytime use the

caps

23 and 25 are exposed to the view of the user of the gun.

The two beads 20 and 2l are spaced apart to provide a clearance through which the target can be seen and these beads are so positioned relative to each other and to the beads I0 that when the rie is xed on the target, the beads on the two sights will define a peep hole 26. When the sights are positioned for daytime use or use in bright light, the heads i3 and 23 will expose their white surfaces while the head 25 will expose its dark surface, as shown in Figure 6. It has been found in practice that an arrangement of this kind enables the user of the firearm to quickly locate the target within the two sights so that time frequently lost in trying to bring the one sight into line with the other sight is eliminated. Furthermore by providing exposed surfaces of contrasting colors, the target can be more readily distinguished while aim is being taken whether said target is of a light shade or a dark shade.

When the firearm is to be used in the dark, it is desirable to reverse the two sights so as to bring the luminous surfaces thereof toward the user. Consequently, when proper aim is taken at a target, the luminous beads can be easily located relative to each other in order to bring them into clustered relationship as indicated for example in Figure 3.

It will be noted that the base I5 has an extension or tongue 21. This can be snapped into engagement with either of two nodes 28 diametrically disposed relative to the pivot element I6 so that the front sight thus can be held in either of two positions.

By pivotally mounting the base 2, and providing a frictional contact between the tongue 5 and the supporting member I, the rear sight can be adjusted laterally about its pivotal connection 3 to allow for windage.
