Specification of Letters Patent. Patented Sept, 19, 1916.

Application filed January 10, 1916. Serial No. 71,324.

To all whom it may concern Be it known that I, BRIAN C. BULLEN, a citizen of the United States, and a resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and Improved Sight for Firearms, of which the following is a full, clear, and eXact description.

This invention relates to sighting devices for firearms and has for an object the provision of an improved arrangement to be used in target shooting whereby more accurate firing may be produced.

Another object in view is to provide an adjustable circular front sight so as to encircle the bulls-eye when the device is in use.

A still further object in view is to provide a sighting device at the front and rear of the firearm which may be adjusted to produce any sized opening so as to shut out all undesirable rays of light while allowing the eye to view the bulls-eye and a small space around the same.

In the accompanying drawing: Figure 1 is a plan view of an iris diaphragm; Fig. 2 is a plan view of an iris diaphragm with a base connected thereto forming certain features of the invention; Fig. 3 is a side view of a rifle and target, certain parts being shown in perspective, illustrating the use of the sights thereon.

Referring to the accompanying drawing by numerals, 1 indicates "an ordinary iris diaphragm which is adapted to be soldered or otherwise rigidly secured to a standard 2, as shown in Fig. 3, which standard may be adjustable and which standard is .also pivotally mounted at 3 so as to be moved out of the way or up into an operative position. An operating arm 4 of any desired structure is provided for the diaphragm 1 whereby the opening may be increased or decreased as preferred. As shown in Fig. 2, and also on the front of the rifle shown in Fig. 3, the iris diaphragm structure 5 is provided with an arm 6 at one side for opening and closing the shutters of the diaphragm. A base 7 is rigidly secured to the diaphragm in any suitable manner so as to be fitted on to the front of the rifle barrel in correct position.

As shown in Fig. 3, a target 8 is disclosed provided with a bulls-eye 9, the arrange ment being such that when a person using the rifle looks through the iris diaphragms 1 and 5 the bulls-eye will be seen and a circle of white 10 will also be seen around the bulls-eye. The iris diaphragm 1 at the rear of the rifle is used in the capacity of what is known as a peep-sight, while the iris diaphragm 5 at the front is adjusted so that a person looking through the peep-sight at the rear will look through the opening at the iris diaphragm 5 and will see the bullseye 9 1n the center of a white circle. This arrangement of sights is preferable for only comparatively short distance, as for instance, from 100 yards to 800 yards. From this it will be observed that the front sight will, in a certain sense, frame the bulls-eye .and the entire bulls-eye will be seen regard less of the distance. WVhen the distance is short the iris diaphragm 5 is adjusted so that the opening therein will be of a proper size to merely disclose the bulls-eye and a slight space around the same, which is also true when the bulls-eye is at a great distance.

In the use of ordinary bead sights at the front it is usually necessary for part of the sight to obscure part of the bulls-eye in or der to correctly sight the rifle, and in doing this the bulls-eye is often obscured to such an extent as to cause the shot to be directed at some other spot. By providing an adjustable diaphragm structure having an infinite adjustment the entire bulls-eye may be observed and a slight clear space around the same which, when thus observed, insures the rifleman that his sight is correct.

What I claim is:

1. In a' sight of the character described, the combination with a rifle, of a sighting member .at the rear of the rifle, an iris diaphragm at the front of the rifle. said diaphragm being provided with a foundation or base connected to said rifle and with an operating lever for producing any desired aperture.

2. In a device of the character described, the combination with a rifle, of an iris diaphragm front sight, and an iris diaphragm rear sight, the iris diaphragm front sight being such as to cause the bulls-eye to be encircled and framed when the rifie is in use.

3. In a sight of the character described,

a peep-sight arranged at the rear of the bulls-eye on a target and a slight open rifle, and an iris diaphragm arranged at space around the bulls-eye in case the rifle the front of the rifle, sald iris diaphragm is correctly aimed.

being formed With a base and means for BRIAN C. BULLEN. adjusting the shutters of the diaphragm Witnesses:

whereby a person looking through the peep VICTOR C. BULLEN,

and through the front sight may see the J. D. BIROHENOUGI-I.

Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. 0.
