To all whom t may concern.'

Be it known that I, EBENEZER REGINaLn MORRIS, a subject of the King of Great Britain, residing at Sydney, in the State of New South Vales, Commonwealth of Australia, have invented certain new and useful I mprovements in Riiie-Periscopes, of which the following is a specication.

This invention relates to an improved rifle periscope, its object being to enable a soldier or other person to aline the sights along the barrel of his rifle from one side thereof by reflection at right angles, while he is protected by earthworks, sandbags, or other suitable cover.

The invention consists essentially in attaching to the barrel of the rifle by means of a strap, clip, or other fastening, a small mirror arranged at an angle of 45o to the usual line of sight, and substantially horizontal therewith.

But in order that the invention may be clearly comprehended, I now refer to the accompanying drawings, in which,

Figure l is a perspective view of my periscope atachment for sighting from the right, while Fig. 2 is a similar View for sighting from the left side. y

Fig. 3 is a partial elevation of a rifle showing the periscope attachment in position.

Fig. 4 is an elevation showing the method of using the attachment, while Fig. 5 illustrates in perspective an attachment in which a double mirror is pivoted and may be changed from one side or the other according to the position taken up by the person aiming.

The same reference letters indicate the same or corresponding parts.

A is a mirror preferably secured in a suitable casing B, having a semi-circular portion C capable of fitting over the barrel of a rifle in line with the sights and behind the rear sight. D is a flexible strap for fastening the attachment in position on the barrel by means of the buttons, E, E. F is the barrel, and G is a portion of the stock. J is a sighting aperture in the casing which is also open at its front K.

In using the periscope attachment the muzzle end of the rifle is rested on any convenient object, such as a sandbag, while the rifleman takes up a position at one side facing the mirror thereby enabling him to aline the sights by reflection. At the same time he grasps the butt with one hand the thumb of his other hand being in contact with the trigger of the rifle as clearly shown in Fig. 4.

In Fig. 5, the mirror is a double one and with the casing B is made adjustable on the lower portion C around a pivot pin I-I or the like preferably situated between the two refleeting faces of the mirror so that the sights of the rifle may be aligned from either side according as the facilities afforded by the cover require.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent, is

1. A periscope attachment for rifles, comprising a casing portion; a supporting portion whereon said casing is rotatably mounted, adapted to detachably engage the barrel of the rifle behind the rear sight; and a double mirror within said casing arranged in the line of the sights and at an angle of approximately 45 thereto; said mirror.being moved by the rotation of said casing in one direction or the other into position to enable the marksman to aline the sights from either side of the rifle by direct reflection.

2. A periscope attachment for rifles, comprising a casing rotatably mounted upon the rifle barrel behind the rear sight; and a double mirror within said casing arranged in the line of the sights and at an angle of approximately 45 thereto; said mirror being moved by the rotation of said casing in one direction or the other into position to enable the marlrsman to aline the sights from either side of the rifle by direct reflection.

3. A periscope attachment for rifles, comprising a box-like casing mounted upon the barrel of the rifle behind the rearsight and having its front open; and a vertical double mirror within said casing arranged in the line of the sights and at an angle of approximately 45 thereto; said casing having sight openings in its sides.. located opposite said mirror, said mirror being moved by the rotation of said casing in one direction or the other into position to enable the marksman to aline the sights from either side of the rifle by reflection directly visible through the adjacent sight-opening.

In testimony whereof I have hereunto set my hand.

EBENEZER REGINALD MORRIS.
