Abstract
A transport for measuring strikes and dips. The transport includes a locking mechanism for locking the needle assembly n place. The needle assembly can be momentarily released to allow a measurement to be made, and then locked to allow the measurement to be viewed. The transport also includes external levels to allow a user to level the transit while viewing from the sides or underside. Another unique feature includes clinometer dials incorporated on the hinge between the cover and transit body.
Claims38
A compass, said compass comprising:
- a needle assembly for indicating directions;
- a mounting mechanism for said needle assembly for allowing said needle assembly to be moved from a first position where said needle assembly is freely movable and a second position where said needle assembly is locked from movement;
- a locking mechanism for moving said needle assembly from said first position to said second position;
- and
- a release mechanism for momentarily releasing said needle assembly from said second position to allow a measurement to be taken and then returning said needle assembly to said second position.
A transit for measuring strikes and dips, said transit comprising:
- an inclinometer mechanism for measuring dips;
- a needle assembly for measuring strikes;
- a mounting mechanism for mounting said needle assembly in a first position to enable said needle assembly to measure strikes and in a second position to lock said needle assembly in a fixed position;
- a locking mechanism for moving said needle assembly from said first position to said second position;
- and
- a release mechanism for momentarily releasing said needle assembly from said second position to allow a measurement to be taken and then returning said needle assembly to said second position.
A transit for measuring strikes and dips, said transit comprising:
- a cover;
- a body;
- a hinge for mounting said cover to said body;
- a leveling device;
- at least one clinometer dial mounted to said hinge for measuring the degree of angle between said cover and said body;
- a needle assembly for measuring strikes;
- a mounting mechanism for mounting said needle assembly in a first position to enable said needle assembly to measure strikes and in a second position to lock said needle assembly in a fixed position;
- a locking mechanism for moving said needle assembly from said first position to said second position;
- and
- a release mechanism for momentarily releasing said needle assembly from said second position to allow a measurement to be taken and then returning said needle assembly to said second position.
A transit for measuring strikes and dips wherein said transit comprises:
- a body;
- a needle assembly for measuring strikes mounted in said body;
- at least one leveling device mounted on the exterior of said body for indicating that said needle assembly is in a horizontal plane;
- a mounting mechanism for mounting said needle assembly in a first position to enable said needle assembly to measure strikes and in a second position to lock said needle assembly in a fixed position;
- a locking mechanism for moving said needle assembly from said first position to said second position;
- and
- a release mechanism for momentarily releasing said needle assembly from said second position to allow a measurement to be taken and then returning said needle assembly to said second position.
