ROBERT 1B. GILMORE, OF MORROW, OHIO.

GUN-SIGHT.

Specification of Letters Patent.

Patented Jan. 11, 1916.

Application filed July 6, 1915. Serial No. 38,208.

To all whom it may concern:

Be it known that I, ROBERT B. GILMORE, a citizen of the United States, and a resident of Morrow, in the county of lVarren and State of Ohio, have invented certain new and useful Improvements in Gun-Sights, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to gun sights in which a peep sight is provided in connection with a channel sight.

It has as its object the providing of such a sight adjustable for either nature of sight at any desired range.

A further object thereof is to provide a peep sight which is very easy to find with the eye, and also to provide a sight in which there are various sizes of peep and sizes and shapes of channels.

These objects I accomplish by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings, Figure l is a side elevation of a gun barrel with the sight in section. Fig. 2 is a perspective view of the sight. Fig. 3 is a vertical section of the gun barrel taken behind the sight. Fig. 4 is a longitudinal section of the modification of the sight which is adjustable for different sized openings. Fig. 5 is an end elevation of the said modified sight. Fig. 6 is a perspective view of the rotatable sight portion of said adjustable sight. Fig. 7 is a detail showing the mounting plates therefor.

The gun barrel 1 has at its end the sighting pin 2 which is to be used with either the peep or the channel sight. The mounting plate 3 of the sight is provided with a dovetailed block .t which is adapted to slide into a groove in the barrel of the gun, fitting in tightly so as to securely mount the sight on the barrel without its being subject to chance displacements. This block is at the forward end of the mounting plate and the other end is slotted at 5 to receive the range pin 6. The range pin has alternate ridges 7 which are graduated as to height, the depressions being used for the peep sight, and the top of the ridges for the channel sight as will be described. The operation of this pin consists in pushing it in for longer range and pulling it out for shorter range, the pin wedging up the rear end of the sight by forcing it away from the surface of the barrel. A notch is cut in the slot 5 to engage over the ridges 7, so that the mounting plate can sink into the depressions.

The sight in its simpler form comprises a block 8 having a Vshaped channel 9 in its upper surface. This channel is used for sighting together with the pin 2 when the range pin is in a position with one of its ridges in the slot in the channel of the mounting plate.

The peep sight hole 10 is bored through the block 8 just below the base of the channel 9. This sight is to be used when the mounting plate is raised up on one of the ridges of the range pin. The two sights combined make it very easy to get a proper sight in connection with the pin 2 at the end of the gun barrel, because the gunner in aiming can easily get the pin 2 in line with the object and the bottom of the channel, and from this position it requires but a small movement to bring the eye to the peep at just the right position. It is hard for eyes that are not very strong to find a peep at all and the channel serves as a guide for the eye as well as a preliminary sight finder.

Some eyes will follow a small peep and a narrow channel only with great difiiculty, and this is common with older people whose eyes are below normal. Accordingly it is designed to provide for channels of different sizes and for peeps of different sizes on a rotary piece which operates on a like theory to the simpler form now described. In this modification, two vertical plates 11, 11 are formed on the mounting plate, said plates having apertures 12, 12 for the spindle 13 of the rotary piece 14. Cut in this piece are preferably the two V-shaped channels l5, 15, one wider than the other, and two U- shaped channels 16, 16, one wider than the other. The two plates 11 and 11' have notches 17 cut in them, so as not to interfere with the eye in sighting along the channels, and below the notches are the apertures 18, 18, in line with the peep holes 19 in the rotary member. The peep holes 19 are of varying sizes and the two holes 18 are large enough to accommodate any of the peeps.

Mounted below the rotary member on the mounting plate is a spring finger 20, which presses against the surface of the rotary member and serves to hold it in such position as it is turned by the operator. It can be seen that this modification embodies the itsraaa same idea as the simpler form first clescribed, and that the same advantages follow from its use, with the additional advantage that the user of the gun can turn the rotary part to the position best adapted for his eye.

It will be noted that the peep holes are larger at their forward end, this being for the purpose of permitting the slight tipping of the Sight, without obscuring the view of the sight pin at the end of the barrel.

It is not desired that the claims that follow be limited to specific structure, where general terms are used, in view of the fact that various modifications might suggest themselves to the mechanic which have not been mentioned in this specification.

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

1. In a gun sight, the combination with a sighting pin at the end of the barrel of the gun, of an elongated block having a channel, and a tubular peep hole through the block located ust below the base of the channel.

2. In a gun sight, the combination with a sighting pin at the end of the barrel of the gun, of an elongated block having a channel, a tubular peep hole through the block located just below the base of the channel, means for mounting said block on the barrel of the gun, and means for positioning the block for sighting with the channel and with the tubular peep hole.

3. In a gun sight, the combination with a sighting pin at the end of the barrel of the gun, of an elongated block having a channel, a tubular peep hole through the block 10- cated just below the base of the channel, means for mounting said block on the barrel of the gun, and means for positioning the block for sighting with the channel and with the tubular peep hole, said latter means being adjustable for varying ranges.

4. In a gun sight, the combination with a sighting pin at the end of the barrel of the gun, of a rotary member having a series of channels of varying sizes cut longitudinally on its periphery, and a series of peep holes through said member located ust below the channels, said holes being or varying sizes.

5. In a gun sight, the combination with a sighting pin at the end of the barrel of the gun, of a rotary member having a series of channels of varying sizes cut longitudinally on its periphery, and a series of peep hole; through said member located just below the channels, said holes being of varying sizes, means for mounting said rotary member on the barrel of the gun, and means for positioning it for sighting with the channels and with the peeps.

6. In a gun sight, the combination with a sighting pin at the end of the barrel of the gun, of a rotary member having a series of channels of varyin sizes cut longitudinally on its periphery, and a series of peep holes through said member located just below the channels, said holes being of varying sizes, means for mounting said rotary member on the barrel of the gun, and means for positioning it for sighting with the channels and with the peeps, said latter means being adjustable for varying ranges.
