AT TUR/V57' gli? Patented Dec. 23, 1952 TELESCOPE MOUNTING FOR GUNS Donald D. Demick and Joseph J. Bartolat, Tacoma, Wash.; said Demick assignor to said Bartolat Application February 16, 1951, Serial No. 211,286

4 Claims.

The present invention relates to a telescope mounting for guns and it consists in the combinations, constructi-ons and arrangements of parts herein described and claimed.

Generally the invention comprises the provision of an iron sight provided with windage and elevation adjustments and which iron sight forms a part of a telescope sight mounting of that type shown, for example, in the patents to Redfield, No. 1,837,290 of December 22, 1931, and Buehler, No. 2,486,002 of October 25, 1949. The iron sight forming the present invention may be adjusted for windage and elevation With respect to the gun upon which the same is mounted and, when once so adjusted, need not be further disturbed even when the telescope sight is mounted upon or removed from the telescopic sight mounting of which the present invention forms a part.

It is accordingly an object of the invention to provide a device of the character set forth which is simple in construction, inexpensive to manufacture and yet effective and efficient in use.

Another object of the invention is the provision of an iron sight forming a part of a conventional telescopic sight mounting.

A still further object of the invention is the provision of an iron sight forming a part of a telescopic sight mounting and having novel means for adjusting the elevation and windage positions thereof.

Other and further objects of the invention will become apparent from a reading of the followingv 'specification taken in conjunction with the drawing, in which:

Figure 1 is a side elevational View of an embodiment of the invention,

Figure 2 is a plan view thereof.

Figure 3 is an exploded perspective view of the elements forming the present invention,

Figure 4 is an enlarged sectional View taken along line 4-4 of Figure 2, and

Figure 5 is an enlarged sectional view taken along li-ne 5--5 of Figure l.

Referring more particularly to the drawing, there is shown therein a rifle I0 upon which a gun sight mount II is engaged for securely mounting thereon a telescopic sight (not shown). The presently described mount I I is of that type shown in the Buehler patent above referred to but is not necessarily confined to that showing, it being understood that the present invention may be applied to other telescopic gun sight mountings of similar character.

The mount II is provided with a fixed base I4 having a front base section I5 and a rear base section I6 connected together by a side arm I1 which side arm or connecting bar I'I is formed as an extension of the front and rear sections on one side of the base I4. The front base section is provided with vertically extending openings for the reception of bolts I8 or the like and the rear base section I6 is provided with an opening for the reception of a bolt I9 or the like, such bolts I8 and I9 being adapted to maintain the base I4 in fixed position upon the rifle I0.

The front end of the base I4 is formed with a pair of forwardly extending clamping arms 20 and 2| which form an adjustable clamp 22 at this end of the base III within which a front telescopic sight-engaging ring (not shown) may be mounted, the arms 20 and 2| being formed with a peripheral opening 23 for this purpose. A set screw 24 engages through the outer ends of the arms 20 and 2|.

The rear portion I6 of the base II is formed with a pair of notches or cut outs 25 on the opposite' sides thereof. The notches 25 open through the upper and lower surfaces of the base II and are substantially annular for partially enclosing the round heads 26 of bolts engageable in the base section I6.

The bolts 21 are provided with annular heads 26 having an inner concave surface as shown at 28. Flanges 29 are thereby formed about the annular head 26 and the shank of the bolt 21 extends concentrically from the center of the head 26. The bolts on the opposite sides of the base portion i6 are oppositely threaded, that is, one of the bolts is threaded for left hand rotation and the other threaded for right hand rotation.

A rear telescopic sight-engaging ring (not shown) is adapted to be releasably engaged by the iianges 29 in the manner shown, for example, in the Buehler patent above referred to.

The windage adjustment for the telescopic sight is made by properly positioning the screws 2l. After the proper adjustment is made for the telescopic sight, the left screw, as viewed in Figure 4 of the drawing, remains constantly in the position thus found and is never turned again, and the other of the two screws 21 is removed and replaced when the telescopic sight is removed from or replaced upon the rifle, it being understood that the mount II remains upon the riie I0 at all times.

The device forming the present invention consists of a block 30 which is adapted to extend transversely across the rear base portion I6 and which is provided at either side with an arcuate slot 3| into which may be engaged the anges 29 to thereby hold the block xedly in position atop the mount I The block 30 is centrally provided with a longitudinally extending depressed portion 32 and the rear face of the block 30 is provided with a recess 33 in which a flat sight plate 34 is vertically slidable, the shoulders 35 formed by the recess 33 in the block 30 acting as vertical guideways for the plate 34.

Adjacent the up-per and outer corners of the recess 33 the block 30 is provided with threaded openings 36 and the plate 34 is provided with a vertically extending slot 31 adjacent each side thereof, the slots 31 being adapted to register with the openings 36 in the lblock 30.

A pair of screws 38 extend through the slots 31 and engage in the openings 36 by which means the plate may be held in various selected vertical positions upon the block 30. The plate 34 is centrally provided with a sight opening 39.

A threaded opening 40 extends angularly downwardly and outwardly from the depressed portion 32 of the block 30 to the lower end of one side of the block 30 and a windage screw 4| is threaded therein. The screw 4| is provided with a head 42 and a tapered nose 43 which is adapted to engage beneath the flange 29 of the screw 21 adjacent to its side of the block 30.

A threaded opening 44 extends inwardly from the front face of the block 30 and communicates with the threaded opening 40, as clearly shown in Figure 4, and a set screw 45 is threadably mounted in the opening 44.

nmperanton, it will be apparent that when the rings supporting the telescop'icmsig are removed from the mount that the block 33 may be .engaged by the flanges 29 entering the arcuate .grooves 3| and that thereafter the proper windage setting for the block 30 and consequently the 'sight plate 34 may be had by manipulating the heads 26 of the screws 21 until a proper alignment is had between the sight opening 39 and the forward sight of the rifle. When this has -been properly ascertained, the screw 4| may be threaded inwardly in the opening 40 until the tapered nose 43 engages beneath the concave surface 28 of the screw head 2B adjacent that side of the block 30. This action having taken place, the set screw 45 is threaded inwardly of the block 30 to thereby abut against the screw 4| to maintain the same xedly in position in its opening 40. Thereafter, no further windage adjustment will ever be necessary for the block 30 or the plate 34 since it is only necessary to remove the right hand screw 21 as viewed in Figure 4 to release and replace the block 30 upon the mound To set the proper elevation for the plate 34 and its sight opening 39, it is only necessary to loosen the screws 38 and adjust the proper vertical position of the plate 34 thereafter tightening the screws 38 to maintain the plate 34 xedly with respect to the block 38. Hence it will be seen that once the Iproper windage and elevation adjustments have been made for the device forming the present invention it will only now be necessary to insert the block 30 and its attached elements into engagement with the flanges 23, as aforesaid after the telescopic sight has been removed from the rifle I and Without further adjustment being necessary. The present device furnishes an iron sight for a rifle equipped with a mount for telescopic sights, it being understood that ordinarily, when a telescopic sight mount is placed upon a rifle, the conventional rear sight or iron sight becomes useless due to the fact that the mount itself is interposed in the line of sight between the conventional rear sight and the conventional front sight of the rifle.

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claims.
