The invention relates to a telescope mount of the type for affixing a telescope upon firearms.
It is one of the objects of the invention to provide a mounting for telescopes which can be accurately and rigidly aflfixed in a definite position relative to the firearms so that the telescope can be used for accurate sighting.
One of the essentials of an accurate telescope mount is its strength while obtaining rigidity, easy removal, and accurate and precise alignment. These features are essential because of the fact that the mount may be frequently removed and attached in transporting firearms so as to avoid damage to the mount or the scope.
It is one of the objects of the invention to provide an attachment plate for telescope mounts which has an apex thereon formed by two flat intersecting faces in combination with a bracket to which the telescope is connected, wherein the bracket is arranged to have complementary or companion seating faces to engage those on the base.
Another object of the invention is to provide complementary interfitting faces on a telescope mount base and upon the telescope supporting bracket with an attaching piece which will draw the two faces together to hold them firmly in rigid position for accurate alignment of the telescope.
Another object of the invention is to provide a bracket for telescopes having an offset flange portion for attachment to the firearm.
Still another object of the invention is to provide a telescope bracket and base which are simple and economical to manufacture and which may be readily attached and which will accurately support the telescope.
Other and further objects of the invention will be readily apparent when the following description is considered in connection with the accompanying drawing, wherein:
Fig. 1 is a side elevation of a firearm to which the telescope mount has been aflixed.
Fig. 2 is a section taken on the line 2-2 of Fig. 1, looking in the direction of the arrows and illustrating the parts in section.
A firearm 2 having a barrel 3 is shown in side elevation and the telescope mount is affixed thereto by attaching the base plate 4 to the barrel of the gun by means of the cap screws 5.
Fig. 2 shows that this plate 4 has a concave surface at 6 to fit the periphery of the gun barrel 3. The opening 1 in the plate and opening 8 in the barrel are in alignment so that the cap screws 5 will accurately align and aflix the base plate relative to the axis of the firearm.
The base plate 4 has an upwardly inclined face l0 which serves as a seat for the bracket M.
It should be particularly noted that the face i0 is of considerable size and area, being the length of the plate 4 as seen in Fig. l and of substantial width, as seen in Fig. 2.
The upper inside portion of this base plate 4 is provided with a face or shoulder |2 which is rather narrow but is inclined upwardly and outwardly so as to merge with the face H] in a crown portion l3. This crown is in the form of a line longitudinally of the barrel and accurately aligned, due to the afiixing of the plate upon the gun barrel. While the base is shown as removable by the use of the cap screws 5 it may be welded to or made integral with the a barrel if desired.
The faces l0 and I2 form a seating area which is arranged to receive the bracket II. This bracket H is formed with the fore and aft ring portions l5 which are in the form of spring clamps adjusted by means of the screws I6 so as to clamp the telescope firmly and accurately in place.
The bracket II has a flange 20 thereon extending downwardly and laterally as seen in Fig. 2. This flange has a lower face 2| which is smooth and substantially the same size and shape as the base ID. The flange 20 also has a shoulder 22 which is a companion to the shoulder I2 on the base plate. The faces 2| and 22 therefore 'merge together in an apex 23 which is adapted to seat upon the crown l3.
The construction just described provides for the companion faces I0 and 2| and the companion shoulders or faces l2 and 22 and seating upon each other respectively so that an accurate alignment of the bracket is obtained, relative to the gun barrel 3.
The cap screws 25 may have knurled heads for easy removal and are shown as threaded into the openings 26 in the base plate and passing thru the openings 2'! in the flange 20 of the bracket These openings may be of a size or shaped to allow a sliding movement of the flange and particular attention is directed to the fact that these openings 26 and 21 are inclined at an angle other than perpendicular to the inclination of the faces 2| and I0 so that when the screw 25 is drawn up tightly there will be a tendency to pull downwardly a slight amount upon the flange 20 so as to be sure and seat the shoulders l2 and 22. This inclination serves the purpose of also drawing the faces ID and 2| firmly together so that in every instance and upon every occasion when the bracket is clamped to the base, the telescope itself will be in actual and accurate alignment with the gun barrel.
Broadly the invention contemplates a telescope bracket and base plate making up a telescope mount which will have great strength and rigidity, which can be easily removed, and which will provide for accurate and precise alignment of the telescope relative to the gun barrel. The foregoing advantages are obtained with ease and simplicity in manufacturing and sturdiness in construction.
What is claimed is:
1. A telescope mount for firearms comprising a base, means to fix said base to the firearm, a pair of fiat upper faces on said base each inclined upwardly and meeting along aline to form a crown seat, a telescope bracket,- a pair of fiat tapered faces on the undersideof said bracket forming an upwardly converging-apex, and means to affix said bracket on the base with the crown and apex interfitted and the complementary faces seated so as to provide a readily removable rigid and precise alignment of the bracket and base.
2. A telescope mount for firearms including a base plate, means; to affix the plate at one side of the firearm,'said, plate having an arcuate portion to fit the firearm, an upper seat face on said plate inclined upwardly and above the firearm, a stop shoulder on. said plate to define an apex in section with said seat face, whereby a crown composed by said face and shoulder is formed to receive a telescope, a telescope bracket having a flange, a face and a shoulder thereon to fit said base plate crown formed by said face and shoulder thereon respectively, and means to afiix said bracket to said plate.
3. A telescope mount for firearms including a base plate, means to affix the plate at one side of the firearm, said plate having an arcuate portion to fit the firearm, an upper seat face on said plate inclined upwardly and above the firearm, a stop shoulder on said plate to define an apex in section with said seat face, whereby a crown composed by said face and shoulder is formed to receive a telescope, a telescope bracket having a flange, a face and a shoulder thereon to fit said base plate crown formed by said face and shoulder thereon respectively, and means to affix said bracket to said plate including a member to pass thru the flange and into said plate and inclined at an angle to said faces so as to tend to fit said bracket firmly on said crown.
4. A telescope bracket including an open circular portion to receive the telescope, a flange extending laterally therefrom, a seat face on the underside of said flange, a shoulder merging with said face and forming an apex extending parallel to the optical axis of the telescope, and a base for accurately fitting said bracket to the firearm, and means to affix the bracket to said base which means extends thru said flange at an inclination to said face and shoulder.
5. A telescope mount for firearms including a base plate, means to aflix the plate on the firearm, said plate having a portion to fit the firearm, an inclined seat face on said plate, an inclined stop shoulder on said plate] to define with said seat face an upwardly pointed apex in section, whereby a crown composed by said face and shoulder is formed to receive a telescope, a telescope bracket having a flange, a face and a shoulder thereon to fit said base plate crown formed by said face and. shoulder thereon respectively, and means to affix said bracket to said plate including a member to pass thru the flange and into said plate.
