| Number | Title | Issue Date |
| 6829837 | Miter angle indicating tool A miter angle indicating tool includes three members that are pivotally attached. The miter angle indicating member is adapted to display the miter angle in or around a corner requiring a miter joint, or to display the bisecting angle of an object. Once the required... | 12/14/2004 |
| 6823596 | Template and method for trisecting an angle A transparent plastic template permits an angle to be conveniently truncated with a pencil and straight edge. The template has three holes equally spaced apart along a hypothetical line, a central hole and a pair of outer holes. A circle is centered about one of the... | 11/30/2004 |
| 6553678 | Austin triangle I have discovered it is possible to find an indirect measurement if the vertex angle is given and the sides and the diameter are given. Using an instrument having the shape of an isosceles triangle it is possible to have a vertex angle and two congruent s... | 04/29/2003 |
| 6553683 | Method and apparatus for generating a template A method for defining a regular or irregular shape utilizes a template apparatus including a plurality of radially-adjustable corner members connected by length-adjustable straight edge members. The corner members include an angle scale to display the def... | 04/29/2003 |
| 5894671 | Compass with angle trisecting capability A new geometric instrument-compass for a practical use that allows the trisection of an arbitrary angle as well as retains its effective functionality for operations that can be performed by the conventional compass is disclosed. The design proposed makes... | 04/20/1999 |
| 5383276 | Angle trisector An angle trisecting device with a base section having two angle indicating scales and an elongated member with a straight edge portion. The elongated member is pivotally mounted on the base section. A given angle on one angle indicating scale coinciding w... | 01/24/1995 |
| 5210951 | Trisector An instrument for trisecting an angle has two circular plates and four pointers. Two pointers are to define a given angle which can be an acute angle or obtuse angle. Two other pointers are to divide the given angle into three equal angles when they are p... | 05/18/1993 |
| 4866848 | Instrument for subdividing angles into halves, thirds or fifths A simple drawing instrument for the subdivision of angles into halves, thirds and fifths comprises two planar pieces connected at a pivot point. Each piece has three curved edges, being the external edge of the part and the two edges of a curved slot with... | 09/19/1989 |
| 4068380 | Device for dividing an angle Device for dividing an angle into equal or proportional parts, comprising the surface flattened or not of a right cone, of which the axis is adjustable through the vertex of the angle, on which surface a describing line and a number of lines corresponding... | 01/17/1978 |
