NED BISIBEE, OF GLENCOVE, WASHINGTON.

FRONT SIGHT.

Application filed March 10, 1915.

To all whom it may concern:

Be it known that I, NED BISBEE, a citizen of the United States, and a resident of Glencove, in the county of Pierce and State of lVashington, have invented a new and Improved Front Sight, of which the following is a full, clear, and exact description.

The invention relates to guns, rifles and other firearms, and its object is to provide a new and improved front sight arranged to permit the user to take correct aim during the dawn or in dark forests or under other conditions in which the ordinary front sight becomes indistinct. In order to accomplish the desired result use is made of Specification of Letters Patent.

Patented Feb. 8, 1916.

Serial No. 13,420.

sight in either of two positions, as hereinafter more fully explained. The head 0 is preferably of diamond shape in cross section and is provided at the top with a sighting point (Y to be viewed through the notch or opening in the usual breech sight of the firearm. One end of the head C has tapering sides terminating in a central point C coinciding with the axial line of the head, as will be readily understood by reference to the drawings. The other end of the head C is provided with a top surface C inclined downwardly and outwardly from the sighting point C and this inclined surface is brightened either by polishing. 'tlonhyicoata front si 'ht havin a slo )in bri ht sur-K' ng it With an enamel, weferablmoi. White :3 b 1 b C face leading to the sighting point on the top of the sight to enable the user of the firearm to readily see the sighting point through the notch or opening in the breech sight. Use is also made of a bearing mounted on the front end of the barrel and in which bearing is mounted to turn the base of the front sight to allow of turning the latter into a position for use in bright light or for use in dim light.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of a portion of a firearm provided with a front sight in position for use in bright light; Fig. 2 is an enlarged plan view of the front sight; Fig. 3 is an elevation of one end of the front sight; Fig. 4 is a side elevation of the same; Fig. 5 is an elevation of the other end of the front sight; Fig. 6 is a cross section of the same on the line 66 of Fig. 2; Fig. 7 is an inverted plan View of the same; Fig. 8 is a longitudinal central section of the same on the line 88 of Fig. 2; and Fig. 9 is a cross section of a modified form of the front si ht.

On the top of the barrel A near the front end thereof is arranged a reversible front sight B constructed to permit its use while bright light conditions prevall or during dawn or while the user of the gun is in a dark forest or under other conditions under which the ordinary front sight becomes indistinct. The front sight B consists essentially of a head C, a shank D, a baseE, a bearing F and a spring or other retaining means G for holding the head of the front tints The shank Dis'iifthe form of a thin plate, concave at its front and rear edges so as to prevent entanglement of the sight with brush, vines or the like. The base E is preferably made circular and is provided with a flange E mounted to turn in the bearing F, and the said flange E is provided with flattened parallel portions E E, either of which is adapted to engage the flat spring G held in the bearing F, plainly shown in Figs. 7 and 8. hen the head G is in the position shown in Figs. 1, 2, 4:, 7 and 8 then the flat portion E bears against the spring G and the central point C of the head extends rearwardly toward the breech sight. The front sight is in this position under bright conditions but under dim conditions the user gives a half turn to the front sight so that the brightened surface C extends toward the breech sight and hence the user of the gun in sighting can readily see this brightened surface which leads to the sighting point C, thus enabling the user of the gun to obtain accurate aim when using the gun in dim light. It is understood that when the front sight is given a half turn the flattened surface E moves out of engagement with the spring G, and the other flattened surface E moves into contact with the said spring to hold the front sight in reverse position, as above described.

The base of the bearing F is preferably dovetailed to permit of conveniently sliding it in position on the barrel A.

In practice, the head 0 is made separate from the shank D and is soldered or otherwise secured thereon, while the base E and the shank D are formed of an integral piece.

As shown in Fig. 9, the head C and the shank D are formed of an integral piece while the shank D is made separate from the base E and is soldered or otherwise secured thereon.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A firearm provided with a reversible front sight having an angular fiat and obliquely disposed surface the apex of one angle of said surface merging into the sighting point of the sight.

2. A front sight for firearms provided with a top sighting point and having an angular shaped fiat and obliquely disposed bright surface the apex of one angle of said surface coinciding with the top sighting point.

3. A front sight for firearms having a head, one end of which is diamond shaped and the other end is provided with an inclined bright surface leading to the sighting point on top of the head.

l. A front sight for firearms having a head approximately diamond shape in cross section, one end of the head having tapering sides and the other end having an inclined top surface leading to the top point of the head.

5. A front sight for firearms, comprising a head, a shank and a base, the head having a sighting point on top, one end of the head having tapering sides leading to a central point and the other end of the head having an inclined bright surface leading upwardly to the said sighting point.

6. A front sight for firearms comprising a head approximately diamond shape in cross section and having a top sighting point dividing the sight into two sections of differing degrees of brightness.

7. A front sight for firearms comprising a head approximately diamond shaped in cross section having a top sight dividing the same into two sections of difiering degrees of brightness, one end of the head having tapering sides terminating in a central point coinciding with the axial line of the head.

8. In a firearm, the combination of a bearing on the front end of the barrel, and a front sight held reversible in the said bearing, one end of the said front sight being relatively dull and having a central apex or point, the other end having an oblique fiat bright surface.

9. In a firearm, the combination of a bearing on the front end of the barrel, and afront sight held reversible in the said bearing, one end of the said front sight being relatively dull and the other end having an oblique fiat bright surface leading to the sighting point on top of the sight.

10. In a firearm, the combination of a sight bearing on the front end of the barrel, a front sight having a head, shank and base, the said base being mounted to turn in the said bearing, the said base having fiattened parallel portions, and a spring held on the said base and adapted to bear against either of the said flatened portions.

11. In a firearm, the combination of a sight bearing on the front end of the barrel, a front sight having a head, a shank and a base, the said head having a top sighting point and one end of the head having tapering sides leading to a central point and the other end of the head having an inclined bright surface leading to the said sighting point, the front and rear edges of the said shank being concave and the said base havlng flattened parallel portions, and a fiat spring held in the said bearing and adapted to bear against either of the said flattened base portions.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

NED BISBEE.
