Abstract
An angle measuring apparatus includes a housing that has a circular aperture, and a rectangular slot positioned such that a length of the slot is in parallel with the circular aperture. A rotating assembly has a needle pointer, positioned within the circular aperture and is operative to rotate, with the needle pointer maintaining a position with respect to the housing as the housing is moved angularly with respect to a reference position, such that the needle pointer indicates the direction of gravity. A transparent insert, that has indicia for indicating measurement angles, is operative to be removably inserted into the rectangular slot such that the indicia are superimposed over the rotating assemble and operative for use as reference indicia as the rotating assembly rotates.
Claims17
An angle measuring apparatus comprising:
- a housing comprising a circular aperture, and a rectangular slot positioned such that a length of the slot is in parallel with the circular aperture;
- a rotating assembly comprising a needle pointer, positioned within the circular aperture and operative to rotate, with the needle pointer maintaining a position with respect to the housing as the housing is moved angularly with respect to a reference position, such that the needle pointer position indicates the direction of gravity;
- and
- a transparent insert, comprising indicia for indicating measurement angles, the transparent insert operative to be removably inserted into the rectangular slot such that the indicia are superimposed over the rotating assembly and operative for use as reference indicia as the needle pointer rotates.
An apparatus comprising:
- a housing comprising a circular aperture, and a rectangular slot positioned such that a length of the slot is in parallel with the circular aperture;
- a rotatable needle pointer comprising a weighted downward pointing indicator;
- a transparent cap, enabling the weighted downward pointing indicator to be visible therethrough;
- an end cap, coupled to the rotatable needle pointer and to the transparent cap;
- and
- a transparent insert, removably insertable into the rectangular slot, and comprising an indicia operative for a measurement purpose using the rotatable needle pointer to indicate direction of gravity, the indicia visible and superimposed over the weighted downward pointing indicator when the transparent insert is removably inserted into the rectangular slot.
