ABSTRACT:
A device for marking the proper position for the threaded fasteners used to secure the leaves of a butt hinge to and between opposable surfaces, which surfaces are to be made hingably movable relative to each other is disclosed. The device includes at least one hinge leaf locator plate which is sized and shaped to conform to the leaf of a hinge whose fastener positions are to be marked. The locator plate contains a series of sharp pointed pins which are arranged thereon and spaced apart from one another in the same manner as the centerline of the fastener holes located in the leaves of the hinge which is to be mounted to and between the opposable surfaces. The series of pins have pointed end portions which project in opposite directions from the locator plate to permit marking by impressions of the pin heads on both opposable surfaces simultaneously for maximum accuracy. The device also includes a backing member having a flat backing surface which is adapted to rest against a surface which is perpendicular to one of the opposable surfaces being marked to provide accurate alignment for the fasteners of both hinge leaves. The device may have more than one locator plate attached to the backing member and the plates may be adjustable to bring any desired one of them from a storage position to an operative position.
