ABSTRACT:
This invention relates to a multi-purpose framing tool and refers more specifically to a hand held tool for inserting nails into picture frames and the like to secure the sides of the frame in the assembled state and for securing the finished work in the frame.
It is known to use a bench mounted press for the insertion of “V” nails in the corner of frames to securely connect the sides and ends of the frame and there are also tools which insert nails and flexi-points into the sides of the frame to hold the work in the frame. However, such machines, especially those for the insertion of “V” nails, are reasonably expensive and therefore are generally only used by professional framing organizations. They are also required to be affixed to a bench, work table, or they may be free standing and are not readily portable.
It is an object of my invention to provide a hand-held tool which is inexpensive, readily portable and which is capable of carrying out both of the aforementioned operations.
A further object is to provide a tool which is also capable of applying supporting screws and other hanging or hinging devices for the picture wire thereby being of particular benefit to hobby framers and the like.
According to one form of the invention, a hand-held framing tool comprises means for retaining fasteners to be applied to a work surface and an anvil head for driving said fasteners thereinto, the retaining means being displaceably located in a bore of said anvil head and having a portion extending forwardly of said anvil head, said forwardly extending portion of said retaining means being adapted to receive and retain a fastener against said anvil head and being retractable in said anvil head against biasing means to permit the anvil head to drive said fastener into the work surface, either of said anvil head or retaining means being a magnet.
A further feature of the invention resides in the provision of a chamfer on at least one side of said anvil head, said anvil head having a blind slot or groove in or adjacent said chamfer.
A still further preferred feature of the invention resides in the provision of a chamfer on opposite sides of said anvil head, each said chamfer having a blind slot or groove in or adjacent thereto.
Another feature of the invention resides in the provision of a slot or slots in the anvil head to receive and retain screw-eyes or other retaining devices for insertion in the rear of the frame to facilitate attachment of a support wire or the like.
