UNITED STATES JAMES R. MAPES, 0F CANASERAGA, NEW YORK.

GUN SIGHT.

Application filed November 9, 1920. Serial No. 422,833.

To all whom it may concern:

Be it known that I, JAMES R. MArEs, a citizen of the United States of America, residing at Canaseraga, in the county of Allegany and State of New York, have invented new and useful Improvements in Gun Sights, of which the following is a specification.

The object of the invention is to provide a gun sight adapted for rigid attachment to the stock in advance of the hammer and in such a position relative to the same as to avoid the risk of contact thereof with the face of the user due to the recoil of the gun or in bringing the piece to the shoulder for a snapshot, and which shall have means for adjustment both to align the sights or allow for windage, and to vary the elevation; and furthermore to provide an improved construction of peep sight whereby light is permitted to penetrate to the peep hole to facilitate accuracy on dark days or in a poor light and to facilitate the finding of the mark without the distracting or confusing incident to a blur; and with these objects in view the invention consists in the construction and combination of parts of which a preferred embodiment is shown in the draw-- ing, wherein Figure 1 is a side view of the sight ap plied in the operative position to a gun of conventional form.

Figure 2' is an enlarged view of the same.

Figure 3 is a rear View.

Figures 4 and 5 are respectively sectional views of the planes indicated by the lines 4--4 and 5-5 of Figure 3.

Figure 6 is a plan view.

Figure 7 is a transverse section on the plane indicated by the line 7-7 of Figure 2.

Figure 8 is a detail sectional view showing the connection of the adjusting screw with the sight block.

The device consists essentially of a frame or yoke having a cross bar 10 and side bars 11, of which the latter may be permanently secured as by screws 12 to the sides of the frame or stock, a sight block 13 movable longitudinally of the cross bar and hence transversely of the gun barrel, and a gauge bar 14 carrying the block and provided with arms 15 which are slidingly mounted in the frame and are preferably dove-tailed as shown in detail in Figure 7 and fitted in corresponding channels 16 in the side bars of the frame.

The vertical movement of the block to provide for varying the elevation of the sight is accomplished by means of pinions 17 connected by a spindle 18 and engaging rack teeth 19 on the arms 15, a retaining spring 20 being arranged in engagament with one of said pinions for locking the parts in their adjusted positions without interfering with the movement'of the pinions, by the finger of the opeartor in either direction to either raise or lower the sight block, as will be obvious by reference to Figures 4 and 5.

The block is slidingly mounted upon the gauge bar 14 and is engaged by a feed screw 21 extending longitudinally of said gauge bar and terminally provided with a finger hold or head 22 by which it may be turned to move the block laterally in either direction either to secure alignment of the sights, that is to say of the rear sight with the fore sight, or to adjust for windage.

The sight block is of the peep sight type having the peep hole 23 with which communicates an upwardly extending slot 24 serving to admit light to the peep hole not only to clear the sight when the light is relatively dim but to facilitate the fin ding of the mark and enable the operator to more accurately aim the piece or draw a finer bead upon the object of the shot.

The means of adjustment as will be seen are within convenient reach of the fingers of the hand arranged on the grip of the gun in position to operate the trigger, to the end that the instantaneous adjustment either to compensate for windage or to vary the elevation may be secured, and the blurring frequently incidental to the use of a peep sight due to an inability to at once discern the mark through the hole of the sight is avoided by enabling the operator to keep the mark in view as the gun is moved into position for the shot.

Having described the invention, what is claimed as new and useful is:

A rear sight for guns consisting of a yoke having a cross bar and slotted side bars of which the latter are adapted for terminal securement by screws to the sides of a gun Stock, marines glc lablsmlet eitudinally, of the cross bar and provided with an adjusting screw for hand manipulation, a transverse spindle paralleling the cross bar and spanning the side bars in which it is journaled, pinions mounted on of one of the pinions to maintain the same in a desired position of adjustment, the said spindle being provided with a hand hold for 10 rotating it.

In testimony whereof I afiix my signature.

JAMES R. MAPES.
