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 weight, positioned within the circular aperture and is operative to rotate, with the weight maintaining the position of the rotating assembly with respect to the housing as the housing is moved angularly with respect to a reference position, such that the weight position 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.
Claims19
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 weight, positioned within the circular aperture and operative to rotate, with the weight maintaining the position of the rotating assembly with respect to the housing as the housing is moved angularly with respect to a reference position, such that the weight 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 assemble and operative for use as reference indicia as the rotating assembly 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 pointing disc comprising a weight and a downward pointing indicator aligned with the weight;
- a bearing, operatively coupled to the pointing disc;
- a transparent cap, coupled to the pointing disc and enabling the downward pointing indicator to be visible therethrough;
- an end cap, coupled to the pointing disc;
- and
- a transparent insert, removably insertable into the rectangular slot, and comprising an indicia operative for a measurement purpose using the rotatable pointing disc to indicate direction of gravity, the indicia visible and superimposed over the downward pointing indicator when the transparent insert is removably inserted into the rectangular slot.
An apparatus comprising:
