Abstract
Abstract An improved beam deflector having a first ball element attached to a second ball element with the first ball element mounted in a movable socket, movable about a single axis only through the first ball element. The second ball element is mounted in a fixed socket and is rotatable about a single axis only through the second ball element. The fixed socket is fixed to the housing of the beam deflector. Rotational movement is limited by the spacing between opposing flat surfaces of the movable and fixed sockets. The movable socket is remotely movable in response to movement of a control rod which is coupled to the movable socket through a universally movable third ball and socket arrangement.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
217 words
A beam deflector for deflecting a beam of emitted energy from a first path to one of a plurality of second paths which are disposed to impinge upon a target working area comprising: a housing enclosing a chamber, said housing having a first port in a first side for receiving said beam into said chamber along said first path and a second port in a second side through which said beam exits said chamber along one of said second paths; deflecting means within said chamber for intersecting said first beam and deflecting said first beam along anyone of said plurality of second paths; control means coupled to said deflecting means for remotely moving said deflecting means from outside said chamber whereby any of said second paths can be selected, said deflecting means comprising: a first ball element mounted in a first socket which socket is rotational throughout a preselected angular range about a first axis only through said first ball element; a second ball element attached to said first ball element mounted in a second socket for rotational movement throughout a preselected angular range about a second axis only through said second ball element, said second socket attached to said housing; and a mirror element carried by said first socket and disposed to intersect said first path.
Claim 2
Dependent Claim
217 words
A beam deflector for deflecting a beam of emitted energy from a first path to one of a plurality of second paths which are disposed to impinge upon a target working area comprising: a housing enclosing a chamber, said housing having a first port in a first side for receiving said beam into said chamber along said first path and a second port in a second side through which said beam exits said chamber along one of said second paths; deflecting means within said chamber for intersecting said first beam and deflecting said first beam along anyone of said plurality of second paths; control means coupled to said deflecting means for remotely moving said deflecting means from outside said chamber whereby any of said second paths can be selected, said deflecting means comprising: a first ball element mounted in a first socket which socket is rotational throughout a preselected angular range about a first axis only through said first ball element; a second ball element attached to said first ball element mounted in a second socket for rotational movement throughout a preselected angular range about a second axis only through said second ball element, said second socket attached to said housing; and a mirror element carried by said first socket and disposed to intersect said first path.
Claim 3
Dependent Claim
25 words
The beam deflector of claim 1 wherein said first and second axes are in parallel and spaced apart planes but said axes are not parallel.
Claim 4
Dependent Claim
22 words
The beam deflector of claim 2 wherein the projections of said first and second axes onto a single plane are not perpendicular.
Claim 5
Dependent Claim
18 words
The beam deflector of claim 3 wherein the opposite acute angles formed by said projections are approximately 15°.
Claim 6
Dependent Claim
66 words
The beam deflector of claim 1 wherein said control means comprises: a third ball element mounted for universal movement within a third socket coupled to a third side of said housing; an adjustment lever coupled to a first side of said third ball element and said deflecting means; and a control rod coupled to a second side of said third ball element opposite said first side.
Claim 7
Dependent Claim
16 words
The beam deflector of claim 5 wherein said adjustment lever is coupled to said first socket.
Claim 8
Dependent Claim
48 words
The beam deflector of claim 1 wherein opposing sides of said first and second sockets are spaced apart from one another by a predetermined distance wherein said preselected range of angular rotation is limited by engagement of said opposing sides, whereby ease of finding the beam is facilitated.
