Abstract
Abstract An improved mounting stage of the type used for the detection of laser beams is disclosed. A stage center block is mounted on each of two opposite sides by a pair of spaced ball bearing tracks which provide stability as well as simplicity. The use of the spaced ball bearing pairs in conjunction with an adjustment screw which also provides support eliminates extraneous stabilization components and permits maximization of the area of the center block laser transmission hole.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
115 words
An adjustable mounting stage comprising: base means having two opposite sides and an end wall, each side including a pair of spaced ball bearing support means mounted proximate opposite ends of said base means without intermediate support means; a rectangular block adapted for sliding movement along the spaced ball-bearing support means; and an adjustment screw journaled at the end wall and threaded into one end of the block for reversibly moving the block along the ball-bearing support means; the adjustment screw including a knob for facilitating rotation, and said stage further comprising ball detent means between the end wall and the knob for preventing undesired rotation of the knob and associated movement of the block.
Claim 2
Dependent Claim
115 words
An adjustable mounting stage comprising: base means having two opposite sides and an end wall, each side including a pair of spaced ball bearing support means mounted proximate opposite ends of said base means without intermediate support means; a rectangular block adapted for sliding movement along the spaced ball-bearing support means; and an adjustment screw journaled at the end wall and threaded into one end of the block for reversibly moving the block along the ball-bearing support means; the adjustment screw including a knob for facilitating rotation, and said stage further comprising ball detent means between the end wall and the knob for preventing undesired rotation of the knob and associated movement of the block.
Claim 3
Dependent Claim
30 words
The adjustable mounting stage of claim 1, further comprising spring biasing means between the end wall and the block for preventing undesired movement of the block on the adjusting screw.
Claim 4
Dependent Claim
26 words
The adjustable mounting stage of claim 1, the block further comprising an aperture having a diameter substantially corresponding to the length and width of the block.
Claim 5
Dependent Claim
30 words
The adjustable mounting stage of claim 3, further comprising spring biasing means between the end wall and the block for preventing undesired movement of the block on the adjusting screw.
Claim 6
Dependent Claim
26 words
The adjustable mounting stage of claim 1, said stage being adapted for mounting a second mounting stage for providing adjustment along a second axis of movement.
Claim 7
Dependent Claim
19 words
Components for a two-stage mounting system, comprising a pair of adjustable mounting stages as set forth in claim 5.
