ABSTRACT:
An adjustable template device for positioning over a sheet material for use in framing and cutting the sheet material to a selected shape comprising a plurality of slidably interconnected frame members forming a closed polygon. Each frame member comprises a guide edge for guiding a cutting blade and a socket adjacent one end of the guide edge for slidably receiving a portion of an adjacent frame member so that the guide edges of adjacent frame members form the sides and one corner of the polygon formed by the device. Each of the guide means has a plurality of detents which are engageable by a pin associated with each socket to retard relative sliding of adjacent frame members. The guide edges are preferably provided with a plurality of slots for receiving a cutting blade so that a cutting blade can extend in the slots to fully cut the corners formed by the frame members. At least some of these slots are positioned relative to the detents to ensure alignment with the adjacent cutting edge. In a second embodiment, each frame member has a curved support surface against which the adjacent frame member is held with an adjustable gripper member.
