FRONT RIFLE SIGHT Filed May 12, 1936 ii e5 /a BBGEUMUHIUAL mawumms.

Patented Oct. 20, 1936 UNITED STATES PATENT GFFICE 6 Claims.

This invention relates to a front rifle sight to be used in connection with the conventional peep rear sight or the like.

It is particularly aimed to provide a construction enabling the marksman to make changes of inserts in less time than heretofore, by avoiding a construction utilizing screws or threads or other parts to become worn and loose; a construction which may be manufactured at a minimum cost; a construction whereinthe insert or sighting device will always be rmly held in proper position and a construction which because of the length of the hood or outer ser-@n.,theiusettlevice for directing the tow d the front, lthe sight i shaded so that the vnl'arksman can sh-ot to l e easteven'after the sun is quite low without beingftroubled with the glimmer of the sun upon is sights.

It is also aimed to provide a novel structure wherein a minimum number of parts are employed, held in operative position by a novel spring latch and wherein the parts do not have to be completely separated for the changing of a sight.

The more specic objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawing illustrating an operative embodiment.

In said drawing:-

Figure 1 is a View showing the improved sight in side elevation operatively positioned on a gun barrel, the latter being shown fragmentarily;

Figure 2 is an enlarged longitudinal sectional view taken vertically through the improved device;

Figure 3 is a cross sectional View taken on the line 3-3 of Figure 2;

Figure 4 is a cross sectional View taken on the line 4 4 of Figure 2;

Figure 5 is a cross sectional view taken on the line 5-5 of Figure 2;

Figure 6 is an elevation of one form of sight insert;

Figure '7 is an elevation of a second form of sight insert, and

Figure 8 is an elevation of a third form of sight insert.

Referring specifically to the drawing wherein like reference characters designate like or similar parts, I0 illustrates fragmentarily, the barrel of a rifle, of conventional form. On the front of the barrel, the improved sight is mounted. This sight consists of a main section II which has an attaching base I2 for instance having a dovetailed projection I3 having an intimate sliding t in a dovetailed recess I4 provided across the barrel Ii). Above the base I2 is a neck I5 and on the latter is a tube or cylinder I6, which extends rearwardly beyond the neck I5, as shown in Figures 1 and 2. Adjacent the forward end of the tube, its wall is slotted as at I'I circumferentially to the extent of substantially 180 and in addition, the inner wall in line with the slot I'I has a groove at I8.

In such slot II and groove I8, sight inserts as detailed in Figures 6, 7 and 8, may be selectively and removably positioned.

The insert, Fig. 6 is applied in the different views and may consist of a blank of transparent celluloid I9, having parts and 2|, of different diameters, so as to occupy the slot Il and groove I8, with the periphery of portion 29 flush with the periphery of the tube I6. On one or both sides of the insert I9, it may have a diametric horizontal groove lled with b lack or other contrasting enamel as at 22, sigv i'ipr'erablyibgprtied at the center 0f the insert as at 23.

Slidably telescoped over the tube I6 is a tubular hood or sleeve 24, which frictionally and intimately embraces the tube I6. 'Ihe hood 24 is preferably made from spring metal, being open centrally at the bottom so as to t the neck I5, the same having depending ilanges intimately engaging such neck. The hood 24 is of the same length as the tube I6 and forwardly of the neck is annularly unbroken so as to be a perfect circle or ring. Integral with such hood 24, is a spring latch 26 which extends through an opening 2l in the neck and has a head 28, provided with a shoulder 29 adapted to normally overlap the outer end of the tube I 6, as shown in Figure 2, to releasably hold the parts assembled, it being observed that the hood 24 extends across the slot I'I and the sight member therein.

It will be noted that a pin or abutment is disposed transversely of the neck Il. This pin serves as an abutment to limit the rearward sliding movement of the hood 24 on the tube I6, since the shoulder 29 will abut such pin, it being understood that prior to the rearward sliding of the hood 24 that the head 28 must be depressed at the forward end, to disengage the shoulder 29 from the tube.

In such retracted position of the hood, the sight insert I9 may be replaced. In the event it is desired to completely detach the hood from the sleeve, the pin 30 may be removed by punching it with the aid of a suitable instrument inserted through an opening 3I in one of the iianges 25, to push such pin outwardly through an aligning opening 32 in the opposite ange 25, when such openings 3| and 32 and the pin 30 are aligned.

In lieu of the sight insert shown in Figure 6, those shown in Figures '7 and 8 may be employed if desired, the same being of substantially the same exterior shape so as to intimately fit the slot I'I and groove I8. The sight I'I is open with the exception of inwardly extending diametric arms 33, terminating in beads 34, in spaced relation, equidistantly on opposite sides of the axis of the insert.

The form of insert shown in Figure 8 is also open and has arcuate arms or projections 35 terminating in spaced relation equidistantly on opposite sides of the axis of the insert, such arms 35 preferably being of the specific shape shown in Figure 8.

The insert of Figure 8 is designed for both target shooting and for hunting as a perfect aim may be taken therewith with less eiort and maintained with less eiort than any other sight. The form of Figure 7 is primarily used for target work and for hunting, its main advantage being the fact that perfect hits can be made after it is too dark to use any other kind of a sight. The form of target insert of Figure 6 is primarily designed for target shooting, specially from a standing position.

It Will be realized that the device, aside from the sight insert, consists only of three parts, namely the main section, the hood, and the pin 30.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.
