GUN-SIGHT.

Specification of Letters Patent.

Patented Oct. 14, 1919.

Application filed February 14, 1919. Serial No. 276,945.

To all whom it may concern:

Be it known that I, FRANK A. VVILLIAMS,

a citizen of the United States of America,

residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Gun- Sights, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to gun sights and has particular reference to a construct-ion of forward sight as hereinafter set forth.

In the drawings:

Figure 1 is a side elevation of a portion of a gun barrel, showing the forward sight mounted thereon;

Fig. 2 is an end elevation of Fig. 1;

Fig. 3 is an enlarged side elevation of the sight assembly detached from the barrel;

Fig. 4 is a sectional end elevation thereof.

Fig. 5 is a section on line 55 of Fig. 3.

In the use of guns for target practice it is at times advantageous to shield the forward sight by a hood, while at other times it is desirable to remove the hood. Where a detachable hood is provided there is always danger of it becoming lost. I have, therefore, devised a construction of hood which, while permanently attached to the gun barrel, may be adjusted in relation to the sight so as to either shield the same or be removed from shielding position.

As shown, A is the gun barrel and B is a collar mounted thereon having an upward extension C with a transversely extending dove-tailed groove D therein for receiving the dove-tailed rib E of the sight mounting E. This sight mounting is preferably adapted to receive a combined blade and peep sight F, which is pivotally secured by the transverse pin G in a longitudinal slot in the mounting. The member F has two arms at substantially right angles to each other, one carrying the peep sight H and the other constituting the blade sight I. Thus either of said arms may be thrown upward by rocking the member F upon the pivot G.

The mounting E is provided at opposite sides thereof with the segmental flanges J and J which extend longitudinally opposite the sight and for some distance in rear thereof. K is a segmental hood member slidably engaging the flanges J and J, being cut away to clear the sight and having at its ends the bead portions L and L engaging correspondingly fashioned grooves M and M in the flanges J and J. The construction is such that the hood is slidable longitudinally of the flanges J and J from a position where it covers and shields the sight, shown in Figs. 1 and 3, to the position where the sight is uncovered, indicated in dotted lines in Fig. 3. To hold the hood in either position of adjustment a detent is provided, this preferably consisting of a spring tongue N struck out from a portion of the hood and engageable with either one of the recesses O and O and the flange J. P and P are apertures through the flange J into the recesses O and O, permitting of the insertion of an instrument for releasing thespring tongue from engagement with the recess. Any pointed instrument will answer for this purpose, a convenient means being the point of a bullet.

In use, when the parts are in position, in Figs. 1 and 3, the hood covers the sight member to efleotively shield the same. Whenever it is desired to remove the protection of the shield the operator by using a bullet or other device for pressing inward the spring tongue N will release the same from the recess 0, permitting the sliding movement of the hood rearward until the spring tongue engages the groove M. This will again effectually lock the hood and hold it in this position of adjustment until it is again desired to return it to shielding position.

For securing the sight mounting E upon the collar B, a pin or screw Q, is engaged with alined apertures in said collar and in the dove-tailed tongue member N. The sight member F is preferably formed with a portion engaging the transverse pin G, centrally slotted transverse to the axis of said pin, as indicated at F. This permits of slightly springing the member in engaging it with its socket so as to produce a resilient tension for holding the member in its different positions of adjustment.

What I claim as my invention is:

1. In a gun, the combination with a sight, of a mounting for said sight extending longitudinally beyond the same, and a hood slidable on said mounting from a position shielding the sight to a position clearing the same.

2. In a gun, the combination with a sight, of a mounting for said sight extending longitudinally beyond the same, a hood slida'bly engaging said mounting, and a catch for looking said hood alternatively in positions for shielding the sight and for uncovering the same.

3. In a gun, the combination with a sight, of a mounting for said sight provided with segmental flanges on opposite sides thereof and extending longitudinally beyond the sight, a hood engaging said segmental flanges to be longitudinally slidable thereon, and a detent for locking said hood alternatively in positions respectively shielding and clearing the sight.

4:. In a gun, the combination with a barrel, of a collar thereon having a transversely extending dove-tailed groove therein, a sight mounting having a dove-tailed tongue for engaging said groove, and a hood longitudinally adjustably secured to said sight mounting.

5. In a gun, the combination with a barrel, of a collar mounted thereon having a transversely extending clove-tailed groovein the upper portion thereof, a sight mounting having a dovetailed tongue engaging said groove, a locking pin for securing said tongue in said groove, segmental flanges on said sight mounting, and a hood longitudinally adjustably secured to said segmental flanges.

6. In a gun, the combination With a sight I of a mounting therefor having segmental flanges on opposite sides thereof a hood lonsi u linal y idably en Said Segmental flanges and provided with a"ietaining bead for preventing lateral disengagement, and a tongue struck out from said hood engageable with recesses in one of said flanges to lock said hood alternatively in diflerent positions of adjustment.

7 In a gun, a sight member having a blade arm and a peep arm in angular relation to each other, a slotted member in which said sight member is pivotally mounted, said sight member having a portion surrounding the pivot slotted centrally transversely to the axis of the pivot and slightly sprung when engaged with said slotted member to produce a resilient tension.

In testimony whereof I alfix my signature.
