Abstract
Abstract A telescopic sight mounting formed of a mounting bar for fastening upon the side of a rifle, and a pair of ring-type scope holding clamps fastened upon the upper edge of the bar, with the forward clamp being pivotable about a vertical axis, and a rear clamp being arcuately movable in a horizontal plane for horizontally adjusting the angle of the scope relative to the rifle, and with the means for holding and moving the rear clamp being normally concealed by the clamp itself.

Total Claims: 7
Claim 1
Independent Claim
345 words
A telescopic sight mounting comprising: a horizontally elongated, narrow, thin bar arranged on one long edge and adapted for fastening in face to face contact with the side face of a rifle in its receiver area; a pair of ring-shaped clamps, each having a base portion arranged upon the upper long edge of the bar, with one clamp near the forward, relative to the rifle, end of the base and the other being near the rear end of the bar, with the two clamps being axially aligned for clamping a telescopic sight extending therethrough in substantially parallel alignment with the bar length and thus the rifle barrel; each base portion having a vertical, downwardly opening, threaded screw receiving opening formed therein; and a vertical opening extending through the bar near each end thereof and aligned with said base openings; and a vertically arranged threaded screw extending upwards through each of the bar openings and being threadedly engaged into the respective base portion openings for thereby screw fastening said clamps directly upon the upper long edge of said bar; and one of said bar openings being of a considerably greater diameter than its screw and being circular in cross section, and a circular bushing rotatably fitted within said one opening, and being substantially covered by its respective clamp base portion, with the bushing having a vertical hole extending therethrough and of a diameter to closely receive its screw, with the hole being parallel to but offset relative to the axis of said one opening, so that rotating said bushing within its opening offsets the screw extending through the bushing relative to the center line of said one opening, wherein the vertical axis of the screw extending through the bushing, and also the clamp threadedly engaged therewith may be adjusted in a horizontal arcuate path, by rotating the bushing into varying positions when its clamp is disconnected from its screw to uncover the busHing, and re-engagement of its clamp and its screw thereby locks its clamp to the bar in such prearranged position and conceals the bushing.

Claim 3
Dependent Claim
58 words
A construction as defined in claim 1, and said screws having heads counter-sunk into the lower edge of the bar, wherein the entire means for fastening the clamps to the bar are concealed by the clamp bases on the upper edge of the bar and the counter-sinking of the screw heads on the lower edge of the bar.
Claim 4
Dependent Claim
66 words
A construction as defined in claim 1, and including a number of vertically arranged notches formed in the upper edge of said bushing, and a small set screw threadably fastened into the upper edge of the bar and partially engaging one of said notches for locking the bushing against rotation, the set screw being beneath and thus concealed by the base portion of its respective clamp.
Claim 5
Dependent Claim
71 words
A construction as defined in claim 1, and including means for fastening the bar to the rifle, comprising screw holes horizontally extending through the bar and arranged in horizontal alignment with pre-existing screw holes used for screw fastening the rifle side receiver cover plate to the rifle, and screws of a length for extending through said aligned screw holes for consequently fastening both the bar and cover together to the rifle.
Claim 6
Dependent Claim
223 words
In a rifle having a side receiver cover plate formed with a number of horizontally axised screw receiving holes through which screws are inserted for fastening the plate to its adjacent rifle structure, and a telescopic sight mounting comprising a horizontally elongated, narrow, thin bar arranged on one long edge and adapted for fastening in face to face contact with the side receiver cover plate of a rifle; and a pair of ring-shaped clamps each having a base arranged upon the upper long edge of the bar, with one clamp near the forward, relative to the rifle end of the bar and the other being near the rear end of the bar, with the two clamps being axially aligned for clamping a telescopic sight extending therethrough, in substantially parallel alignment with the bar length and thus the rifle barrel; the improvement comprising: means for fastening the bar to the rifle, comprising screw holes horizontally extending through the bar and pre-arranged in horizontal alignment with a number of the receiver plate screw holes, and including screws of sufficient length for extending through said aligned screw holes in the bar and plate, replacing the original screws used for originally fastening the plate to the rifle structure, for consequently fastening both the bar and the cover plate together as a unit to the adjacent rifle structure.
Claim 7
