Carpentry measuring tool

A carpentry measuring tool adapted for fitting a door to an existing door frame and comprising:

• a first arm having at least one planar surface formed thereon and adapted for placement in a measuring position for determining interior distances between opposite sides of a door frame;
• a second arm pivotally secured at one end thereof to a first end of said second arm, said second arm being pivotable within predetermined limits with respect to said first arm to form an angle therewith to thereby permit the measurement of an angle formed by interior intersecting surfaces of a door frame;
• a captive slide, one surface of which is formed as an extension of said planar surface, said slide being extensible outwardly from a second end of said first arm away from said first end, said slide being adapted to cooperate with said first arm to measure distances between opposite sides of said door frame;
• beveled heel means being disposed on the distal end of said slide and being spring-biased away from said first end, said beveled heel means being momentarily retractable a predetermined distance toward said first end to permit said first arm to be removed from said measuring position wherein said beveled heel tightly abuts one of said opposite sides;
• first tensioning means engaging said one end and said first end for retaining said first arm and said second arm in a fixed angular relationship to permit the transfer of a measured angle between said intersecting surfaces of said door frame to a door to be mounted therein;
• second tensioning means for retaining said slide in a desired extended measuring position to permit the transfer of a measured distance between said opposite sides of said door frame to said door to be mounted therein;
• nail means for securing said second arm to one of said opposite sides of said door frame;
• a plurality of clips slidably mounted into grooves formed in said second arm on a surface thereof parallel to one of said opposite sides when said second arm is in said measuring position, each of said plurality of clips being captured within one of said grooves and being spring-biased outwardly away from said surface against overlapping portions of said groove, said plurality of clips being extensible to project beyond said second member in a direction substantially parallel to said surface to permit an alignment of said second member parallel to an edge of said door such that said surface is positioned beyond said edge a predetermined distance, said predetermined distance being equal to the difference between the width of said door frame and the width of said door necessary to permit said door to operate freely within said door frame when mounted therein.

A measuring tool comprising:

• a first member adapted for measuring distances between opposed surfaces, and including a captive slide formed as an extension thereof and extensible outwardly from a second end thereof in a direction away from a first end;
• a second member secured at one end thereof to said first end of said first member, said second member being adapted to be pivoted within predetermined limits about said first end of said first member to form an angle with respect to said first member to thereby permit the measurement of angles formed by intersecting surfaces;
• a beveled heel disposed on the distal end of said slide and being spring biased away from said first end, said beveled heel being momentarily retractable toward said first end a predetermined distance upon the longitudinal application of force thereto to permit disengagement of said beveled heel from one of said opposed surfaces;
• retaining means for securing said slide in a selected position to permit the transfer of a measurement of a distance by said first member to a workpiece;
• and
• tensioning means for urging surfaces on said first end against surfaces on said one end to prevent angular movement between said first member and said second member and to thereby permit the transfer of an angular measurement therebetween to a workpiece, said tensioning means comprising:
• a pin interconnecting said first end and said one end;
• means securing one end of said pin to one of said first end and said one end;
• disc means securing another end of said pin to the other of said first end and said one end and having a first inclined cam surface formed thereon;
• a lock washer disposed adjacent said disc means and having a finger anchoring said lock washer in a fixed relationship to the other of said first end and said one end, said lock washer having a second inclined cam surface adapted to cooperate with said first cam surface;
• and
• a handle member attachable to said disc means and adapted to rotate said disc means in one direction with respect to said lock washer to cause said first cam surface to ride along said second cam surface in said one direction and to rotate said disc means in another direction with respect to said lock washer to cause said first cam surface to ride along said second cam surface in said another direction to release tension on said first end against said second end.
