Door hinge applying apparatus

An apparatus for hingedly connecting an adjacent pair of work members each having elongate butt-receiving surfaces, by conventional hingedly connected butt hinges each having butts to be seated in mortises of outlines corresponding to the outlines of the butts, and each butt having a plurality of screw holes in a predetermined pattern for screws to secure said butts in said mortises;

• (a) means for supporting said work members in positions so that said butt-receiving surfaces having said mortises therein are adjacent, parallel, and facing in the same direction for receiving the butts of said butt hinge in said mortises;
• (b) a screwdriver unit, and means connected to said work member supporting means for supporting said unit for movement to and from said mortises when said work members are supported in said positions, and unit-moving means connected with said unit for so moving it;
• (c) hinge supporting means mounted on said unit for releasably supporting said hinge thereon for movement therewith to said mortises and for firmly seating the butts of said hinge in said mortises with one butt in the mortise in one work member and the other in the mortise in the other work member and for holding said butts in said mortises until the butts are screwed to the work members;
• (d) a plurality of screwdriver bits rotatably supported on said unit for movement therewith each in alignment with one of the holes in said butts when said butts are seated in said mortises and means for releasably holding a screw on each bit in said alignment with one of the holes in said butts;
• (e) Means for simultaneously rotating said bits during driving of said screws by said bits and while said hinge is held by said hinge supporting means;
• (f) said hinge supporting means comprising a body formed with butt-engaging surfaces facing the direction of movement thereof toward said mortises for supporting said butts in positions extending divergently relative to each other with their divergent edges spaced apart a lesser distance than the correspondingly positioned sides of the mortises to receive them to facilitate entrance of said butts into said mortises;
• and
• (g) said divergent edges engaging said butts at points spaced from said edges toward the hinged connection between said butts, whereby continued movement of said hinge supporting means toward said mortises after engagement of said divergent edges with said mortises will fully seat said butts in said mortises and whereby said body will hold said butts seated during the driving of said screws through the holes in said butts and into said door and jamb.

In apparatus for hingedly connecting a door and a jamb, each having a flat, butt-receiving surface respectively defining one edge of the door and a longitudinally extending side of said jamb, by butt hinges, each comprising a pair of hingedly connected butts respectively formed with a plurality of screw openings, one butt to be seated in a mortise formed in the butt-receiving surface of said door and the other to be seated in the butt-receiving surface of said jamb, an assembly of units for forming the mortises for each hinge, for drilling screw holes in said mortises, and for securing the hinge butts in said mortises, comprising:

• (a) means for supporting said door and jamb in positions with said surfaces coplanar facing in the same direction with said jamb parallel with said edge of said door and adjacent thereto;
• (b) a mortiser having a cutter for forming the mortises in a predetermined area in each of said surfaces of said door and jamb for the butts of said hinge;
• (c) a drilling unit having a plurality of drills for drilling screw holes for said butts in the mortises formed in said predetermined areas;
• (d) a hinge seating and screw driving unit for supporting and seating one of the butts of said hinge in each of the mortises in said areas and a plurality of bits on said unit for supporting and driving screws through the holes in said butts and into holes drilled in the mortises in said areas for securing said hinge to said door and jamb;
• (e) pivots for supporting said mortiser and drilling unit at fixed points relative to said areas for swinging said mortiser and drilling unit about parallel axes, one after the other, to and away from said areas for forming said mortises and said screw holes when said door and jamb are in said positions;
• (f) a rigid amount supporting said pivots at said fixed points, and said means for supporting said door and jamb in said positions for mortising and drilling including elements on said pivots in engagement with said surfaces;
• and means on said rigid mount for supporting said hinge and screw driving unit for movement to and from said mortises for seating the butts of the hinge carried thereby in said mortises and for driving screws on said bits through the holes in said butts and into holes drilled in said mortises for securing said butts in said mortises.
