GUN -SIGHT.

Specification of Letters Patent.

Patented Dec. 25, 1917.

Application filed November 19, 1914. Serial No. 872,963.

To all whom it may concern;

Be it known that I, EDGAR P. Cook, a citizen of the United States, residing at Granville, in the county of Licking and State of Ohio, have invented a new and useful Gun-Sight, of which the following is a specification.

My invention relates to improvements in gun-sights in which a sighting aperture or notch is made movable in vertical and horizontal directions for the purpose of more readily attaining the desired direction for the guns alinement.

The main objects of my improvement are, first, to simplify the mechanism which attains this result, second, to produce a sight not liable to get out of order, third, to produce a sight of more pleasing appearance than has heretofore been constructed and fourth, to produce a sight which shall be very delicate in its adjustments.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 represents a portion of a gun with this invention attached thereto. Fig. 2, represents a side elevation of this device but showing the opposite side from that shown in Fig. 1 and with the mechanism at its lowest adjustment. Fig. 3 shows a longitudinal section of this device, but with the mechanism raised to its highest adjustment. Fig. 4, shows the arrangement of the outward parts of this device as seen from above, with cup disk 6 removed. Fig. 5 shows a rear view of the device, also with cup-disk 6 removed. Fig. 6 shows a cross section of the device on the line B-B in Fig. 2. Figs. 7 and 8 show the adjusting screws, 4 and 5. Figs. 9 and 10 show two views of the cup-disk 6. Figs. 11 and 12 represent the elemental principle of this invention, the sliding block 2, with the sighting stem 3 attached thereto. Similar reference characters refer to similar parts throughout the drawings.

In the construction shown in the drawings, 1 represents the base or that part in which the working parts of this device are arranged. Where the guns construction will permit this part may be a part of the gun itself. 2, as stated above represents the slidable block and may be of any desired shape to accomplish the purpose desired, and 3 represents the stem or sighting device which is that portion of the general device the shooter makes use of in sighting the gun and may be of any desired shape or size. The particular variety of sight here represented is known as the aperture or peep sight, meaning that the sighting device is provided with an aperture through which the shooter looks in the act of alining the sights with the object to be shot at.

4 is the adjusting screw which regulates the vertical adjustments of the device and 5 is the adjusting screw which regulates the lateral movements of the same. Should it seem desirable to construct this sight with only the vertical adjustment this screw 5 may be omitted. 6 is, as referred to above, a so called cup-disk common to this class of sights, which aids the shooter to more easily center his vision through the aperture. This cup-disk may be omitted in the construction of this sight, in which case the shooter merely uses the stem 3 with the aperture 8, therein. 7 is a slot prepared in the base 1, in which the adjusting screw 5, is positioned. This slot is so arranged that the screw 5 is permitted to turn on its long axis therein, when it is being operated, or to slide up and down therein when necessary to follow the block 2 in its vertical adjustments. 8 represents the aperture through which the shooter directs his vision in the act of aiming the gun. 9 is an opening in the base 1, through which the adjusting screw 5 is positioned within the slot 7 and is made continuous with that slot. 1010 are screws by which the base 1 is attached to the gun. 11 is the slot in the base 1 in which the adjusting screw 4 is positioned and permits that screw to turn on its long axis and to slide from side to side as the other screw 5 moves the block 2. 12 is the slot in the base 1, in which the stem 3 is permitted to move from side to side or in its vertical adjustments.

The operation of the device is as follows :the screw 5 is turned clockwise to bring the sight proper to the right, to enable the gunner to observe and shoot more accurately in that direction; and counter clockwise to obtain the same results in the left-hand direction of the gun, looking from the rear to the barrel end. The screw 4 is stationary, but in being operated, it forces the sight vertically, either up or down, as the screw is turned to respectively cause its raising or lowering.

While only one form of construction of ,this invention is shown in this application,

it is not desired to limit this application for patent to this particular form, as the principles of this invention may be adapted to sights occupying other positions on a gun and of necessity of somewhat different construction, yet coming within the scope of the appended claim. As evidence that I have attained the object before referred to, let it be observed that, omitting the cup-disk 6 and not counting the screws 1010 by which the device is fastened to the gun, there are but four pieces necessary in the construction of this device, namely, the base 1, the block 2 with stem 3 attached and the adjusting screws 4 and 5.

The device will be more pleasing in appearance because of the absence of any of the screws of adjustment projecting above the sighting portions.

The device is not liable to get out of order because the threaded portions of the adjusting screws are entirely protected within the base 1, and finally the adjusting screws being of a large diameter will permit of fine threading and slow twist thereby making for delicacy of adjustment.

Having thus described my invention, what I claim is:

A gun-sight comprising a base having an elongated screwingon piece and having horizontal and vertical slots therein, a slid.- ing block having a sight means attached tlloerehf) andharranged llto move one1 oi the s ots or c angin t e vertica an orifiaialanlassnsiitheastshtn the blocE 35 arranged to indicate by the positions, the relative position of the sight.

In testimony whereof I hereunto afliX my signature in the presence of two witnesses.
