UNITED STATES PATENT ()FFICE.

\ RIFLE-SIGHT.

Application filed March 13, 1907.

To all whom it may concern:

Be it known that l, irlun'noon Evic'r'r SU'rnnnLANn, of Westvillo, in Picton county, Province of Nova Scotia, Canada, have invented certain new and useful improvements in ltille-Sights, of which the followingis a specification.

This invention relates to improvements to rille sights and particularly to leaf sights of the type in which a laterally and. longitudinally adjustable sight operates on a leaf hinged to a base which is secured to the rifle barrel.

The objects of my invention are, first, to provide an auxiliary emergency sight adjustable longitudinally but not laterally, whereby it remains always in its central position ready for instant action; second, to provide a peep sight adjustable with the open sight and which may be moved into the same sighting position as the open sigl'it with out in any way altering the adjustment thereof; the top of the peep sight being adapted in one position to serve as a bar si ht; third, to provide a device whereby the a justment of the elevating screw of the sighting bar may be indicated to the opera tor; and fourth, to provide means for gaging the alinement of the back sight with the foresight when the peep sight is used. The first of these objects is carried out by an auxiliary fixed sight integral with the sighting bar and extending normally thereto. The second by a plate slidably supported in a groove in.

the adjustable sight and having a peep hole therein and which may be moved into sighting position without disturbing the adjust ment of the open sight. The third object is accomplished by a spring detent device 0pcrating on the elevating screw. And. the fourth by forming the peep sight plate of such width as to the blanket sight and prevent its passing to the eye of the marksman when aiming. As aresult, the marksman observes the foresight only through the poophole. The details of these constructions together with those of the remaining part of the sight are fully set forth and described in the accompanying specifications and drawings.

Figure l is a front elevation of the sight with the leaf in raised position. Fig. 2 is the same view with the leaf lowered. Fig. 3 is a side elevation with the leaf lowered. Fig. 4 is a perspective view of the sight in position on the rifle barrel. Fig. 5 1s an enlarged perspective detail of the sighting bar Specification of Letters Patent.

Referring to the drawing, A is the base of any improved form which is suitably secured to the rille barrel B.

C is the leaf hinged at u, to the base and on which operates the sighting bar D, being raised and lowered thereon by means of the elevating; screw The means connecting the elevating screw with the sighting bar do not form part of the present invention. and may be varied to agree with different forms of sights, that I have illustrated being a form invented by me and covered by my United States Patent No. 824,960, which was granted. to me on July 3rd, 1906.

F is the sighting plate of the type shown and described in my aforesaid. United States patent and which is laterally adjustable on the sighting bar by means of the tangent screw G, and has an open V-shaped sight 3) on the top thereof. ln accordance with my invention, plate F is formed with a clove tailed groove 0 on one side thereof, in which fits the peep sight plate H, having a peep hole (1 therein and an outwardly protruding thumb flange 0, by means of which it may be raised. and lowered. The peep sight plate is limited in vertical movement by means of a projecting pin f thereon which takes into a slot 9 formed in the bottom of the groove c. In its uppermost position the peep hole will come on a line with the top of the sighting plate F, and will thus be in the same sighting position as that of the open sight which it covers. To hold the peep sight plate 111 sighting position and to steady its movement, I provide a small compression spring 7L, located in a recess 71 in the plate and adapted to bear on the bottom of the groove 0, and

take into a recess 7' therein. when the peep sight plate is in its up permost and, sighting position. if it is desired. to use the sight as a bar sight the peep sight is sii'nply moved up until the top thereof is on. a line with the top of the sighting plate, provision being made for its retention in this position by means of the recess :0 .in the bottom of the groove and in which the spring 7i takes.

I is the emergency sight plate, having an open Vsha )ed sight It cut therein, and which is [owned integral with the sighting bar 1), thus being adjustable longitudinally therewith on the leaf U, but being lixed from lateral movement. The adjustment of the emergency sight for the different ranges is accomplished by means of ramps .9 and. t formed integral with the base and which en gage the underside of the sighting bar I).

The top Z of the elevating screw It is in accordance with my invention engaged by a plunger m sliding in a recess it provided in a projecting portion 0 of the leaf. The plunger m is pressed outwardly by a compression. spring p and isadapted to successively engage a plurality of small depressions g which are symmetrically arranged around the underside of the head of the elevating screw. The screw E as it enters each depression will cause a slight clicking noise thereby giving warning to the operator of the progress being made in the adjustment by means of the screw E. To take up the wear on the screw E and hold it firmly in position, I provide a thimble t secured to the end thereof having a spring a therein which abuts one of supporting lugs 12 on the leaf, and so normally presses the elevating screw downwardly.

In constructing the sight plate H care is taken that the width of the plate above the peep hole is such as to blanket the light passing through the hood of the foresight and prevent its passing to the eye of the marks man when aiming. As a result the marksman observes the foresight only when look ing through the eep hole and when lookin alcove the ed e 0? the eep sight plate would see nothing of the hood For instance, if too coarse a sight should be taken the operator would observe a line of light between the hood and the peep sight, but if the sight is properly taken then nothing can be seen through the peep sight but a clear, sharp circle, and looking over the top of the peep sight plate nothing can be seen of the circle of the hood. By closely adjusting the width of the peep sight plate this gaging can be carried out to a great degree of fineness, and in addition to indicating whether the sight is too coarse or too fine it will also serve as a check against rolling or canting the rifle, as in either of these cases a line of light will ap pear between the hood and the peep sight.

It will be observed that the emergency sight is always ready for use in the center of the rifle, and no matter what adjustment has been made on the regular sight to account for the windage, yet by lowering the leaf the emergei'icy sight is instantly thrown into action and may be used. from point blank range up to 600 yards.

In using the peep sight adjustment can be made both vertically and laterally as on the open sigl'it, and an important feature of the invention is that having adjusted the open sigl'it for a given range with the desired windage the peep sight can be then moved into the same sigl'iting position as the open sight taking advantage of the adjustment previously made. The change from the open to the poop sight is made by simply sliding up the peep sight plate into position.

While the invention has been herein described with great particularity of detail yet changes may be made therein within the scope of the appended claims without de parting from the spirit of the invention.

What I claim as my invention is 1. The combination with the sighting plate having a dove-tailed groove therein having a smaller groove in the bottom thereof and a recess also in the bottom, of a peep sight plate having its edges of dovetailed shape and slidable in the groove, a pin on the plate entering the smaller groove and a spring adapted to take into the recess when the peep sight plate is in sighting position.

2. In a rifle sight the combination with the leaf and sightin bar longitudinally movable thereon of an elevating screw for the sighting bar located at one side of the leaf, and having the head thereof protruding over the top of the leaf, a projection on the top of the leaf having a recess therein, a plunger sliding in the said recess, and a s ring normally pressing the same outward y against the head of the elevating screw.

3. In a rifle sight the combination with the sighting plate having an 0 on sight therein of a peep sight plate slidab y mounted thereon, the top of said peep sight plate being adapted to serve in a certain position as a bar sight and means for retaining the peep sight plate in either of the two positions whlere it serves as a peep sight or a bar si -1t. I

e. In a rifle sight the combination with the leaf, the sighting bar slidable thereon, the elevating screw for the sighting bar and the supporting means therefor of a thimble secured to the end of the elevating screw, and a spring therein adapted to abut the supporting means of the e evating screw.

5. In a rifle sight, the combination with a circular hood, of a peep sight plate having a peep hole therein, the peep sight plate above the peep hole being of such width as ,to blanket the light passing through the it will readily be understood that certain p hood of the foresight about the foresight and prevent its passing to the eye of the marksman when aiming, whereby the amount of foresight taken may be gaged, as and for the purpose specified.

6. In a rille sight, the combination with the leaf and sightii'ig bar longitudinally movable thereon, of an elevating screw for the sighting bar located. at one side 01 the leaf and having the head thereof 'n'otruding over the top of the leaf, a projection on the top of the leaf having a recess therein and a detent device in said recess operating on the head of the elevating screw, and for the purpose specified.

7. In a rifle sight, the combination with the adjustable sigl'iting plate having a groove formed therein, of a peep sight slidable in said groove and in its innermost position adapted to remain out of sighting position, and a spring adapted to be thrown into operation by the outward sliding of the peep sight and adapted to hold the same in sighting position, as and for the purpose specified.

8. In a rifle sight, the combination with the adjustable grooved sighting plate having a sight formed at one edge thereof and a small groove at the bottom thereof, of a peep sight slidable on the sighting plate,

having a peep hole therein adapted to reg- 9. In a rille sight, the combination with the adjustable grooved sighting plate having a sight formed at one edge of the same and a recess formed in the bottom of the grooved portion, of a peep sight plate slidable in the sighting plate having a peep hole therein adapted to register with the sight on the sighting plate when the peep sight plate is in its outermost position, and a spring on the peep sight plate adapted to take into the recess when the peep sight plate is in its outermost position.
