Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
95 words
In a rifle telescope having one of a movable erector lens assembly and a movable reticle assembly carried in a telescope tube, the improvement comprising resilient means in said tube biasing said assembly vertically and horizontally in said tube, an elevation adjustment means in said tube acting on said assembly in opposition to the vertical bias and a windage adjustment means in said tube acting on said assembly in opposition to the horizontal bias, at least one of said elevation adjustment means and windage adjustment means having a coarse and a vernier overrun adjustment means.
Claim 2
Dependent Claim
95 words
In a rifle telescope having one of a movable erector lens assembly and a movable reticle assembly carried in a telescope tube, the improvement comprising resilient means in said tube biasing said assembly vertically and horizontally in said tube, an elevation adjustment means in said tube acting on said assembly in opposition to the vertical bias and a windage adjustment means in said tube acting on said assembly in opposition to the horizontal bias, at least one of said elevation adjustment means and windage adjustment means having a coarse and a vernier overrun adjustment means.
Claim 3
Dependent Claim
32 words
A rifle telescope as claimed in claim 1 wherein at least one of said elevation and windage adjustment means comprises a direct screw coarse adjustment and an intermediate differential screw fine adjustment.
Claim 4
Dependent Claim
49 words
A rifle telescope as claimed in claims 1 or 2 wherein said at least one of the elevation and windage adjustment means includes a non-linear range calibration dial on said coarse adjustment means and corresponding to any ammunition-rifle combination and a linear vernier adjustment acting thereon for fine adjustment.
Claim 5
Dependent Claim
70 words
A rifle telescope as claimed in claims 1 or 2 wherein the coarse adjustment means is a first screw threaded member having an end engaging said movable assembly for rapid movement of said assembly against the biasing means and said vernier adjustment means is an intermediate screw threaded member threadingly carrying said first screw threaded member for small incremental movement of said first screw against the assembly and biasing means.
Claim 6
Dependent Claim
18 words
A rifle telescope as claimed in claim 4 wherein said intermediate screw is threaded in said telescope tube.
Claim 7
Dependent Claim
33 words
A rifle telescope as claimed in claim 4 wherein both the first and intermediate screw are limited in movement relative to the telescope tube by cooperating stop means on said tube and screws.
Claim 8
Dependent Claim
42 words
A rifle scope as claimed in claim 6 wherein the cooperating stop means include a pin fixed in said tube, a semi-annular slot in said intermediate screw fitting over said pin and a slot in said first screw fitting over said pin.
Claim 9
Dependent Claim
46 words
A rifle scope as claimed in claim 6 wherein first detent means between said tube and intermediate member provide a physical indication of their relative positions and second detent means between said intermediate member and the first member provide a physical indication of their relative positions.
Claim 10
Dependent Claim
46 words
A rifle scope as claimed in claim 7 wherein first detent means between said tube and intermediate member provide a physical indication of their relative positions and second detent means between said intermediate member and the first member provide a physical indication of their relative positions.
Claim 11
Dependent Claim
55 words
A rifle scope as claimed in claim 8 wherein the first detent means includes semi-spherical openings spaced annularly around the intermediate member and spring-loaded ball means in said tube and the second detent means includes semi-cylindrical slots spaced annularly around the first member and radial spring-loaded ball means in the intermediate member engaging said slots.
Claim 12
Dependent Claim
55 words
A rifle scope as claimed in claim 9 wherein the first detent means includes semi-spherical openings spaced annularly around the intermediate member and spring-loaded ball means in said tube and the second detent means includes semi-cylindrical slots spaced annularly around the first member and radial spring-loaded ball means in the intermediate member engaging said slots.
