Claim 5

The instrument as defined by claim 1 in which said first light deflecting means includes an angle indicating means which presents a measure of the angle of light beam deflection.

Claim 6

The instrument as defined in claim 4 in which said angle indicating means comprises two horizontal level indicators located in the horizontal plane at right angles to each other.

Claim 7

The instrument as defined in claim 4 in which the angle indicating means comprises a display device against which a small portion of said light beam projected onto to said first light deflecting means is directed as a check for the angle of light beam deflection.

Claim 8

The instrument as defined in claim 4 in which said angle indicating means comprises a combination of horizontal level indicators and angle of deflection indicators.

Claim 9

The instrument as defined in claim 1 in which said light source is a laser.

Claim 10

The instrument as defined in claim 1 in which said light deflecting means includes a pentagon prism.

Claim 11

The instrument as defined in claim 1 in which the path is defined by measuring support means including graduations marked therealong.

Claim 12

A measuring instrument for optically measuring the coordinate distance between two or more measuring points comprising: a light source for providing a light beam; first means for deflecting said light beam; means for mounting said light source; means for mounting said first light deflecting means, in a first straight line which extends through said light source movable along a first path parallel to said first straight line; registering means mounted for movement along said path; means for defining a second path which extends along a second straight line perpendicular to and intersecting said first straight line; a second light deflecting means; and means for mounting said second light deflecting means for movement along said second path said second light deflecting means being intended for measuring the distance between a pair measuring points in a direction at right angles to the direction of measuring made with the first light deflecting means ;said first path extending to the intersection of said first and second straight lines so that said first light deflecting means can be moved thereto to deflect said light beam to said second light deflecting means.

Claim 13

A measuring instrument for optically measuring the coordinate distance between two or more measuring points comprising: a light source for providing a light beam; first means for deflecting said light beam; means for mounting said light source; means for mounting said first light deflecting means, in a first straight line which extends through said light source movable along a first path parallel to said first straight line; registering means mounted for movement along said path; means for defining a second path which extends along a second straight line perpendicular to and intersecting said first straight line; a second light deflecting means; and means for mounting said second light deflecting means for movement along said second path said second light deflecting means being intended for measuring the distance between a pair measuring points in a direction at right angles to the direction of measuring made with the first light deflecting means ;said first path extending to the intersection of said first and second straight lines so that said first light deflecting means can be moved thereto to deflect said light beam to said second light deflecting means.

Claim 14

The instrument as defined in claim 11 also including a third light deflecting means mounted for movement along said first path, between said light source and said first light deflecting means; said third light deflecting means including means mounted therein for partially deflecting said light beam and partially transmitting said light beam.

Claim 15

The instrument as defined by claim 11 in which at least one of said light deflecting means includes an angle indicating means which presents a measure of the angle of light deflection.

Claim 16

The instrument as defined in claim 13 in which said angle indicating means comprises two horizontal level indicators located in the horizontal plane at right angles to each other.

Claim 17

The instrument as defined in claim 13 in which the angle indicating means comprises a display device against which a small portion of said light beam projected onto to said deflecting means is reflected as a check light beam.

Claim 18

The instrument as defined in claim 13 in which said angle indicating means comprises a combination of horizontal level and angle of deflection indicAtors.

Claim 19

The instrument as defined in claim 11 in which said light source is a laser.

Claim 20

The instrument as defined in claim 11 in which said first light deflecting means includes a pentagon prism.

Claim 21
