REVERSIBLE GUN SIGHT Filed DSG. 13, 1952 H7' rom/Er United States Patent Ollce Patented Dec. 20, 1955 REVERSIBLE GUN SIGHT Ralph M. Jenkins, Orleans, Ind. Application December 13, 1952, Serial No. 325,857

2 Claims. (Cl. 33-52) The present invention relates to an interchangeable gun sight, particularly suitable for use on shot guns.

In trap shooting, some gunmen prefer a white sight, and others prefer a red sight. The red sight is easier to see in bright sunlight and the white sight is easier to see in the shade. Often, it is necessary for the gunman to move between sunny and shaded positions, and it is desirable to change the gun sight to that most easily discernible under the particular shooting conditions.

The present invention therefore has for its object the provision of a reversible gun sight, which may be quickly manually shifted to expose the desired colored sight.

A further object is the provision of such a gun sight which may be applied as a replacement sight on a gun, or may be installed on a gun at the time of manufacture.

Another object is the provision of a reversible gun sight which can be reversed quickly without the use of tools, and which is of simple construction and not liable to get out of order.

In accordance with the present invention I provide a gun sight mounted upon a vertical pivot and provided with a detent to hold the sight in either of two positions turned one hundred and eighty degrees. The detent is released for turning the sight, by shifting the sight upon its axis, and upon turning the sight, the detent holds the sight in its newly adjusted position.

The invention will be described in greater detail in connection with the accompanying drawing illustrating a preferred embodiment of the invention by way of example, and wherein:

Figure 1 shows the invention applied to a shotgun;

Figure 2 shows the gun sight in turned position;

Figure 3 is a longitudinal section through the sight;

Figure 4 is a plan view of Figure 3 with the pivot pin removed;

Figure 5 is an end view of the sight, and;

Figure 6 is an elevation view of the pivot pin.

Referring to the drawing there is shown the muzzle 1 of a shotgun, having my front sight 2 attached thereto. The front sight comprises a hollow rod or tube 3 with buttons 4 and 5 attached to the ends. Preferably the rod has an axial bore 6 and each button has a boss 7 having a pressed fit in the bore 6 so as to hold the button in place. If desired, a suitable cement may be employed to help hold the buttons in place.

Rod 3 is bored vertically at 8 and has a counterbore 9 providing an annular shoulder 11. A second counterbore l2 provides shoulders 13, interrupted by the bore 6 through the tube. A helical spring 14 is inserted in counterbore 9 with its lower end resting on shoulder 11,

and pin 15 is inserted through hole 8 with the head 16 engaging the upper end of spring 14. The head of pin 15 is rounded to conform to the cylindrical form of tube 3, and may have a kerf 17 therein to enable the pin to be threaded into bore 18 in the muzzle 1.

Pin l5 has a bore 19 therein which receives a stop pin 21 adapted to be received in the kerf 22 formed in the lower surface of tube 3. With pin 21 in bore 19 received in kerf 22, the tube 3 cannot turn. However, if this tube is grasped by the fingers and lifted, the kerf 22 raises away from pin 21, this movement being permitted by the clearance between head 16 and the shoulder 13, the engagement of shoulders 13 with head 16 limiting the upward movement of the tube 3. In this position the tube 3 can be turned 180 about pin 15 as the axis, so that either the white button 4 or the red button 5 can be exposed to w'ew.

This construction provides for quickly changing the gun sight from red to white, or vice versa, as desired. All that is required is to grasp the tube 6 between thumb and forelinger, lift the tube and turn it through to expose the desired sight. The pin 21 automatically enters kerf 22 and holds the sight in proper position for aiming when the sight is released.

I claim as my invention:

l. In a reversible gun sight, the provision of a sight supporting member having an elongated body with different sights at each end thereof, said sight supporting member having a transverse bore therein intermediate the ends thereof, a pivot member for supporting the sight supporting member and disposed in said bore with the stem thereof projecting radially outwardly of said sight supporting member for direct attachment to a gun barrel, spring means housed within said bore and acting against said pivot member and said sight supporting member to normally hold the sight supporting member in a depressed position with respect to the longitudinal axis of the pivot member, the external surface of said sight supporting member adjacent the projecting stem of the pivot member being kerfed, and means providing a complemental rib fixed with respect to said pivot member for engaging a kerf in the adjacent surface of the sight supporting member to fix the said sight supporting member in predetermined position, said spring means permitting elevation of the sight supporting member relative to the pivot member to cause relative separation between the engaged rib and kerf whereby to permit rotation of the sight supporting member to another position about the axis of said pivot member.

2. In a reversible gun sight as claimed in claim 1, wherein the rib comprises a pin traversing said pivot member in close proximity to the adjacent surface of the sight supporting member and adapted to be disposed adjacent the gun barrel when the stem of the pivot member is xed thereto.
