Laser square

DETAILED DESCRIPTION An object of the invention is to provide an improved tool for easily generating straight lines across spaces without the requirement of using physical objects at the distant end of the line.
Another object is to provide an improved square for generating straight lines over both short distances to long distances, especially in buildings, walls, roofs and the like.
It is yet a further object to provide an improved speed square for generating straight lines for increasing the types of tasks with which a speed square can be used.
Still an additional object is to provide an improved square for generating straight lines in an economical, efficient and inexpensive manner.
These objects are achieved according to the preferred embodiment of the invention by the provision of a speed square as discussed earlier.
The square is provided with a laser beam emitter such as a laser diode, batteries to power the diode, and a container for holding the diode and batteries.
The body of the square or the part of the square which holds the container, is made thick enough to hold the container, this being about 1 inch thick.
The container would be in the T-bar straight edge and/or the ruler edge, which is perpendicular to the T-bar edge and along the length of the arm.
There would be at least one laser container, and the square could have 4 laser containers with one pointing in each direction in each of the two 90.
degree.
arms, i.

the T-bar edge and the ruler edge.
The speed square would be provided with water or bubble levels parallel to each of the 90.
degree.
arms, for leveling the square or to plumb an object.
