Specification of Letters Patent.

n atented April 9, 1907.

Application filed May 4, 1906. Serial. No. 315,212.

To all whom, it may concern:

Be it known that l, ROBERT EDWIN REAR- Dpiy, a citizen of the Dominion of Canada, residing in tne city of Ottawa, in the county of Carleton, Province of Ontario, Canada, have invented lmprovements in Sights for Firearms; and l do hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to improvements in rifle-sights, and more particularly to mechanism by which a very fine adjustment of the various gages may be had. 4

My invention relates also to the sightingaperture which gives a clear deiinition and perfect alinement of the fore-sight.

Another feature is that my new sight may be applied to a great majority of the sightleaves now in use without alterations to the same.

My invention consists, broadly, in a bar to be applied to the leaf or standard of various types of rilie-sights, and it comprises,

l first, a wind-gage having an adjusting device consisting of a screw having a head so shaped that upon the turning of the same an adjustment equal to degrees or fraction of degrees may be indicated by the sense of touch second, a vertical adjustment of the eyepiece, also by means of a screw having the same features as that of the wind-gage, the range of adjustment being made to extend to a maximum of one hundred yards or more above or below the point to which it has been set 5 third, a sighting -piece carrying two sighting-apertures so positioned that one of the apertures may he used when the sight is in either the vertical or horizontal position 3 fourth, a sighting'- aperture of a U or V shaped form, centrally positioned on the diameter or chord of a half-circle or segment.

The invention comprises also certain other features of construction and arrangement of parts, that will be hereinafter described and claimed.

ln the drawings, Figure 1 is a rear view of the sight as turned up, the leaf being shown in section only. Fig. 2 represents a rear view of the complete sighting-bar as it appears when the leaf is in a horizontal position. Fig. 3 represents a side view of the sighting-b ar on the side where the adjustingscrews are mounted. Fig. 4' represents a face and edge view of a part of the sight-leaf. Fig. 5 represents a face view of the sightingbar with the sighting-piece removed. Fig.

same along the line b b, Fig. 5.

6 represents a transverse section view ofthe sents a face view of the eyepiece-carrier with the eyepiece removed. Fig. 8 is a top view ofthe same. Fig. 9 represents a rear view of the eyepiece. Fig. 10 represents a front view of the same. Fig. 11 represents a modiiication` of the sightingaperture.- Fig. 12 represents a modification of the adjusting device of the sighting-bar. Fig.- 13 represents a modiiication for Vthe rapid adjustment of the eyepiece when using the wind-gage. Fig. 14 represents a section of the vertical adjusting-screw along the line a a, Fig. 3.

The device is composed of three main parts, which will be designated throughout this speciication as, rst, the sighting-bar, (de- Fig. 7 repre-v noted by the letter A;) second, the eyepieeecarrier, (denoted by the letter 13;) third, the eyepiece, (denoted by the letter O.)

The sighting-bar (illustrated by Figs. 5 and 6) is preferably cut out from a single piece of metal. 1 is the central slot for the rifle-leaf. The walls 2 2 of the slot 1 are centrally notched, as at 3. This notch is intended to give clearance to the sighting-aperture. The end 4 of the notch 1 is shaped as shown. lt is slotted lengthwise, as shown at Fig. 6 by 5, and endwise, as shown in dotted lines, Fig. 5. These slots serve as a recess for the friction-piece 6, Fig. 6. The shape of that piece 6 is shown in Fig. 12. The notches 7 7 are the means to retain the same in the recess 5 when pins 8 8 are in position. A spring 9 keeps the piece 6 in frictional contact with the riiie-leaf 10and to iin the sighting-bar on the rifle-leaf a thumbscrew 11 is threaded through the end 4, as shown. lts inner end presses against the center of spring 9 and tightens the frictionpiece 6 against the rifle-leaf 10.

Fig. 12 shows a modified form of the device previously described. This modification aflords a means by which the sighting-bar may be adjusted to one hundred yards, or thereabout, by the sense of touch. The screw 11 is centrally perforated. A pin 12 passes through the same. This pin has an enlargement 13 resting against the spring 9. lt will be seen that the pin 12 passes through the friction-piece 6 and engages the rifle-leaf 10 by means of small indentations 13 on said leaf. The pin 12 has a free movement in the screw 1 1 and friction-piece 6. The part of the pin engaging the indentation is rounded off, and, the indentations being` shallow, it will be TOO evident that'if the `linger be applied on the end of the screw 11 and the sighting-bar made to slide up or down the leaf 1() every time the pin 11 coincides with an indentation it will fall therein, causing a depression of said pin sufficient to be felt by the finger.

Referring again to Fig. 5, the right end 14 of the sighting-bar notch 1 is shaped as Shown. lt is provided with a slot 15, shaped as shown' in'Fig. 6. A screw 16 extends the whole length of the slot and is 'fixed as to its longitudinal movement in the end piece 14 by means of a pin 17 engaging a circular groove 18, which groove is integral with the screw 16. The screw 16 is hereinafter called the "vertical adjusting-screw The head of this screw is triangular in cross-Sectiemfi. e., an equilateral triangle with the corners rounded off, as shown by Fig. 14. This shape will enable the fingers to detect each face of the screw-head when the same is being rotated. It will be evident, therefore, that if one complete turn of the screw causes a nut engaging the same to be moved one degree three faces of the screw-head will have been presented to the finger, while if one-third degree adjustment is required one face only will have been presented.

Referring now to Figs. 7 and S, representing what has been hereinbefore called the eyepiece-carrier7J B, 19 is a notch corresponding to the notch 3 and intended also to clear the sighting-aperture of the eyepiece. 20 is a 'nut made integral with the eyepiececarrier and intended to engage the adjustingscrew 16 of the sighting-bar. 21 is a tongue made to slidably engage the groove S4 of the sighting bar. This eyepiece carrier when connected to the sighting-bar by the two parts above mentioned will on the turning of the screw 16 cause the piece B to move up or down the sighting-bar, the movements corresponding to the direction the screw 16 is being turned. The piece B has a longitudinal groove 22 and a perforation 23, (shown in dotted lines,) adapted to receive the adjustingscrew 24. The head of this screw is shaped. as shown in Fig. 3 1'. e., an equilateral triangle with the head rounded off. This shape serves the same purpose as explained heretofore with regard to the screw 16. The piece B has a projection 26 standing at right angles to the face of the piece B and is shaped ,to protect the head of the screw 24.

Referring now to Figs. 9 and 10, representing the eyepiece C, 26 is the eye-aperture, made U-shaped in this case and positioned, as heretofore explained, underneath the diameter or chord of a half-circle or sector. 27 is the eye-aperture used when the sight is in a horizont-al position. This aperture is positioned at right angles with regard to aperture 26. 35 is a nut made to engage groove 22 of the eyepiece-carrier and to thread on the screw 24 of the same piece. It will be evident, therefore, that since the thread of screw 24 is cut so that one turn represents one degree of adjustment the eyepiece C will be moved exactly as previously explained with regard to the adjusting-screw 16. This screw 24 is the wind-gage screw.

Fig. 13 represents an attachment that may be used in connection with the adjustment of the wind-gage. This figure is a section crosswise on c c, Fig. 9. 28 is a button carrying a stem29, having an elongated perforation 30, said perforation being threaded at its lower end. The threads correspond to that on screw 24. A` short lug 31 terminates the stem. .L1-spring 32 keeps the threaded part of the perforation 30 into engagement with the screw 24. This button is placed in a recess 33 practiced in the eyepiece C. T he operation of this device is as follows: When the button is depressed, the thread on the stem disengages the screw 24, and the eyepiece may then be moved freely from right to left, or vice versa, on the eyepiece-carrier; but whenever in these movements the eye-aperture passes centrally of the sight the lug 31 on the end of the stem will drop in a perforation 36 on the eyepiece-carrier, thereby indicating the central position of the eye-aperture.

The operation of my device is as follows: The rifle-leaf having been raised in the vertical position, the sighting-bar is adjusted to approximately the range required by releasing the friction-piece 6 from the friction-leaf, which is done by unscrewing the said screw Y1.1, by sliding the bar to the graduation indieating the range sought, and rescrewing the said screw 11 tight and the friction-piece 6. Should it then be :found that the range is short, the adjusting-screw 16 may be turned from right to left, when the linger will detect the degrees or fraction of a degree every time one of the surfaces of the screw-head comes forward. lt will be understood that the reverse action of this screw will shorten the range. Should it now be found that the wind deflects the projectile, the wind-gage screw 24 may be brought into action, and as the head of this screw is also provided with a plurality of surfaces the degrees or fraction of a degree may be counted by the sensation on the fingers as each face is presented.

T lay great stress on this perception by the sense of feeling of the minute variations invariably required to be corrected in accurate sighting. This is a great advantage, as the eye need not leave the shooting-point when making corrections in the sighting. This feature is also desirable when shooting` in dark or noisy surroundings.

I am aware that attempts have been made to adjust rifle-sights by the sense of hearing g but one has only to take into consideration the noise occasioned by the reports of firearms to disregard this means.
