TODAY’S PATENT –FRAMING SQUARE

The FRAMING SQUARE was invented by   Timothy B. Carroll (Tallahassee, FL), John Wiley Horton (Monticello, FL), Stephen M. Marshall (Tallahassee, FL) on the 15^th of July 2003 , bearing patent number US6591511B1.

The present invention relates to the field of measurement and marking. More specifically, the invention comprises an improved framing square incorporating fixed pins and slid able carriages which allow the user to more easily mark desired angles on objects to be cut. The present invention comprises an improved framing square having integral features for automating the marking and cutting of angles. The square contains two sliding carriages—one in the body and one in the blade. Each carriage has a deployable pin.

In order to set an angle, the user first deploys the pins in each sliding carriage so that they protrude downward from the square. Next, the user sets the sliding carriage in the body to the desired position and locks it in place. The user then sets the sliding carriage in the blade to the desired position and locks it in place. The two pins protruding from the sliding carriages are then butted against the board to be cut. Once they are in place, the blade of the square will form the correct cutting angle across the board.
