Abstract
A machine for attaching hinges to a door having a carriage movable and longtitudinally positionable along a door edge into which the following elements are integrated: 1. A receiving block for receiving a hinge and screws and positioning them for application of the hinge to the door edge. The block contains apertures for receiving the screws and, subsequently, screw bits for driving the screws through the block. The block is movable from a hinge and screw receiving position to a hinge applying position. 2. A hinge magazine for individually feeding hinges to the hinge block. 3. A screw feeder for feeding screws individually to the hinge block. 4. A screwdriver unit having individually operated screwdrivers each positioned to have its bit received by an aperture in the receiving block and each having an air motor for rotating its screw bit and an air piston for independently moving its screw bit forward to drive a screw. The unit is movable from a retracted position when the block is receiving a hinge and screws, to an engaged position with the screw bits engaged in the apertures of the receiving block, when the receiving block is in position for application of the hinge.
