  • Patent number: 9574862
    Abstract: A multifunctional ergonomic tape measure provides a stopping mechanism within its housing body containing a retractable measuring tape which is engaged by squeezing together the housing body and a hinged arm, thereby clamping the measuring tape firmly between two friction surfaces provided by corresponding friction pads mounted in opposed facing relation on the housing body and the arm. The housing includes a duck-bill extending from the front of the body. The duck-bill has a flat, large surfaced face on the front thereof for reading measurements and for sliding along the edges of building material when making parallel lines. The tape end of the tape provides a thumb hold on its upper portion to aid the user in firmly holding both a pencil or utility knife and the tape end. The tape measure is useful for drawing a radius, to obtain inside measurements, and as a square to mark short length right angle lines.

  • Patent number: 7178246
    Abstract: A cutting assembly is slidably mounted on a T-Square. The T-Square may include a scale having multiple indicia for measured cutting based on the size of the wallboard sheet being cut. The cutting assembly is mounted on a slider which may be clamped at measured positions along the arm of the T-Square. The cutting assembly includes oppositely disposed knife blades which are slidably mounted in a housing and spring loaded on opposite sides of a pivot mount such that when not in use the cutting assembly is urged to level and rests with the two knife blades retracted. As the housing is rotated so as to lower one end, the corresponding knife blade extends from the housing to engage with and score or cut the surface of the wallboard material. The cutting tool may be rotated in the opposite direction to thereby extend from the housing the other blade of the pair of oppositely disposed knife blades.
