.1 Claim. 1

This invention relates to gun sights and more particularly to an improved sight having beads of different color which may be selectively used for sighting the gun as desired.

It is a principal object of the invention to provide an improved sight which is efficient but simple and inexpensive to manufacture, and readily mounted on a gun barrel.

Another object is to provide a multiple bead gun sight attachment which is a unitary structure and comprises a rotary element having a plurality of beads of difi'erent colors selectable for use with different backgrounds, objects, and targets and under different weather and lighting conditions. Such selective bead arrangement permits the person using the gun to choose a sight which appeals to him personally, and eliminates the necessity of blackening or polishing the sight as has been common practice with conventional sights to correct for brightness or darkness.

These and other objects and advantages of the invention are attained by the novel form of unitary rotary sight attachment and employing the construction and arrangement of the parts as hereinafter described and claimed, and illustrated by way of example in the accompanying drawings,in which:

Figure l is a perspective view of a unitary multi-bead sight constructed in accordance with this invention and shown mounted on a gun barrel and which is shown partly broken away;

' Figure -2 is a vertical longitudinal section taken through the sight illustrated in Figure 1, with the gun barrel shown partly broken'away;

Figure 3 is a vertical section taken substantially on the line 3-2 of Figure 1 and looking in the direction of the arrows;

Figure 4 is a similar view taken on the line 4-4 of Figure 2 and looking in the direction of the arrows; and

Figure 5 is a detail view illustrating a modified sight and shown in enlarged scale.

Referring to the drawings in detail wherein like reference characters represent like parts throughout the several views, the numeral Ill designates a gun sight made in accordance with this invention and which is adapted to be mounted on various types of gun barrels. The sight comprises an integral rectangular shaped block l2 which is preferably formed of metal, such as aluminum. iron, copper, brass or other readily machinable material. This block is provided with a lower transversely extending dove-tail portion M which is adapted to fit in a dove-tail groove 2 I6 formed on the top of a gun barrel 18. Extending centrally and longitudinally of the block I2 is a bore 20 which is of a size to receive a beadselector pin 22.

A vertical slot 24 is formed in the block l2 near one end and is in communication with the bore 20, the slot being of suflicient width and depth to rotatively accommodate a bead or sight wheel 25 which is in the shape of a'j'triangle and having sight tips 26, 28 and 30 of different colors.

The multi-tipped sight 25 is suitably mounted on the end of the pin 22 and engages a washer 32, the sight element 25 being revolvable in the groove 24 upon rotation of the selector pin 22. so asto selectively present the different colored beads or tips. To assist in turning the pin 22 on the outer end thereof there isprovided a knurled head 38 which may be readily grasped with the fingers for manipulation of the sight.

To maintain the multi-tipped sight 25 in accurate alignment centrally of the bore 20 a sight-supporting center pin 38 is suitably secured to the inner end of the pin 22 and is arranged to accurately position the sight element 25, the rotary sight being fixedly mounted thereon. The outer end of the centering pin 38 is rotatively journaled in the apertured shoulder portion 40 of the block l2.

For removably locking the sight in position to display a particular bead or sight tip a bore 42 is formed in the base part of the block l2 which communicates with the horizontally extending bore 20 and a spring pressed ball detent 44 inserted. The ball detent 44 is urged to enter the sockets 46 as the beadjsclector pin 22 is rotated to provide a self-centering indexing mechanism for positioning the sight.

The indexing mechanism comprises a spring pressed ball and engaging socket, such as shown in Figure 2, the selector pin 22 being self-centering and prevented from resting in a mid-way position by virtue of the closeness of the sockets whereby there is presented only a small partitioning wall between, the sockets and corresponding to the number of beads on the rotatable sight element.

'As illustrated in Figure 5, the multi-bead rotary sight element may conveniently comprise a metal or plastic body 14 having integral arms 16 having differently colored sight beads 12 fixedly mounted on the outer ends of the arm members, as shown. These beads may be formed of vitreous or colored metal shot and suitably fixed or formed integral with the arms 16. In this manner sight beads of different colors, such as white, black, orange, gold or silver may be provided as desired.

It will be appreciated that the gun sight of the invention is simple of construction and adapted to be mounted on all types of gun bar- A gun sight comprising an elongated sighting block having a dovetail portion on its undersurface, said dovetail portion extending transversely of said block and being located inter- 20 mediatethe ends of the block, said block having a transverse slot in "its upper wall intermediate its ends; said block having a longitudinal bore intersecting said slot, a shaft rotatably supported in the bore. bead sights on one end of said shaft and positioned in said slot for r0 tation, the other end of said shaft extending outwardly from the block to form a finger grip whereby the shaft may be manually rotated, said block having a second bore therein dis: posed'pe'rpendicular to the first named bore and intersecting the latter, said second bore extendshaft.

4 ing through said dovetail portion, said shaft having a series of circumferentially spaced ball seats for selectively registering with said second bore, a ball slidable in the second bore for selectively entering said seats, a plug threaded in the end of the second bore remote from the first named bore, and a spring in the second bore; and biased between the plug and the ball to urge the latter into a' selected seat in the WILLIAM L.
