1 Claim. (Cl. 33-50) This invention relates to improvements in adjustable mounts for the purpose of attaching telescopic sights to guns.
An important object of the invention is to provide a mount which can be placed in proper position on a gun without the necessity of defacing or providing holes for the reception of securing elements.
.Still another important object of the invention is to provide an adjustable mount for scopes which can be readily adjusted for precision shooting.
Still another object of the invention is to provide a scope mounting which is of simple construction and capable of being manufactured and retailed at a moderate monetary figure.
These and various other objects and advantages of the invention will become apparent to the reader of the following description.
In the drawings:
Figure 1 is a fragmentary side elevational view showing a gun with the improved mounting installed thereon, in conjunction with a scope.
Figure 2 is a side elevational view (enlarged) of the mounting.
Figure 3 is a side elevational view of the mounting looking at the opposite side from that shown in Figure 2.
Figure 4 is a section taken on line 44 of Figure 2.
Figure 5 is a section taken on line 5--5 of Figure 2.
Figure 6 is a longitudinal sectional view through the mounting.
Figure 7 is a section taken substantially on line 77 of Figure 6.
Figure 8 is a section taken on line 88 of Figure 6.
Figure 9 is a section taken on line 9-9 of Figure 6.
Figure 10 is a perspective view of the carrier bar.
Figure 11 is a perspective view of one of the scope clamps.
Figure 12 is a perspective view of the gun barrel clamp.
Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 15 generally refers to a gun of conventional construction and having a barrel 16, having a sloping shoulder portion which merges the barrel proper with the usual breech 17. It is upon this sloping or tapering portion of the barrel 16 that the present invention, namely, the mounting 18 is located.
The mounting includes a carrier bar 19, which at its forward end and rearward end portions and at the top side thereof are formed with transverse troughs 20, 21 and these end portions have vertically disposed and threaded openings 22 therethrough.
At the intermediate portion of the bar 19, is a reduced portion 23, the inner walls of which are rounded as at 24, 24.
For the forward and rearward ends of the bar 19, clamps generally referred to by numerals 25, 26 are provided and each of these clamps which are for a telescopic sight unit 27 is composed of an upper clamp section 28 and a lower clamp section 29, the clamp sections having 2,775,817 Patented Jan. 1, 1957 opposed cars 30, 31 formed with threaded openings to accommodate clampscrews 32.
Each clamp section 29 has a pair of depending lugs 33, 34 for straddling the corresponding end of the carrier bar 19 and as shown in Figure 4, the portion of the lower section 29 seats in the corresponding trough 20 or 21, the section 29 having a threaded opening therein to receive a screw 35 (see Figures 4 and 6), after the screw has been disposed through the corresponding opening 22 of the carrier bar 19. One ing, for instance the lug 33 of each clamp 25 or 26, is provided with a set screw 36 which can bite against the bar 19 as shown in Figure 4.
The opposite side edges of the carrier bar 19 adjacent to the forward trough 20 are formed with notches 37, 37 and the bar 19 at this point and vertically therethrough is formed with an arcuate slot 38 on a radius with an opening 39 formed vertically through the bar 19 between the curved portions 24, 24.
The mounting assembly further includes a gun barrel clamp generally referred to by numeral 40 which includes an upper section 41 and a lower section 42. This clamp 40 is tapered so as to snugly fit the tapered portion of the gun barrel 16.
The clamp 40 is a split clamp and the mouth portion thereof is capable of being contracted by an inclined adjusting screw 43 which is disposed through slanting openings in the lip portions 44, 45 of the parts 41 and 42 of the clamp. This permits the clamp to be slid along the barrel and simply clamped in place, at the particularly designated tapered portion thereof. The clamp 40 also has a threaded opening 46 adjacent each end thereof for the reception of a set screw 47.
The upper portion of the clamp is provided with upstanding lugs 48, 48 at the rearward end portion thereof and the inner faces of these lugs denoted by numeral 49 are concave to match the curved or convex portions 24, 24 of the carrier bar 19.
Each of the lugs 48 has an opening 50 to accommodate a set screw 51a. The forward portion of the barrel clamp 40 has upstanding lugs 51, 51 which have flat inner faces denoted by numeral 52 and these lugs are formed with openings 53 to receive set screws 54.
As can be seen in Figure 8, a screw 55 passes downwardly through the arcuate slot 38 of the carrier bar 19 and is threadedly disposed into the clamp 40 between the lugs 51, 51.
As shown in Figure 9, a screw 56 is disposed downwardly through the carrier bar 19 by way of the opening 39 and into the upper portion 41 of the barrel clamp 40, between the lugs 48, 48.
Thus it can be seen, with the scope 27 out of place, the
clamp 40 can be readily disposed into place on the barrel 16, after which the various screw adjustments can be made and then subsequently the scope 27 clamped in place by means of the clamps 25, 26.
Adjustments for Windage can be easily taken care of the horizontal setting of the carrier bar 19 on the barrel clamp 40, through the medium of the curved portions 24, 24, the pivot screw 56 and the screw 55 disposed through the arcuate slot 38 in conjunction with the set screws 54, 54.
While the foregoing description sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the invention, what is claimed as new 1s:
