Door attaching apparatus

A door attaching apparatus for a door having a bottom edge and lateral sides comprising a mobile frame, first upward and second upward frames/positioned on said mobile frame, said first frame being movably mounted relative to said mobile frame upward and downward and forward and rearward, said second frame being movably mounted to said mobile frame to move forward and rearward;

• guide way means connecting said first and second frames in upward and downward sliding relation with means to raise and lower said first frame to said second frame and mobile frame on said guide way means, said first frame having means along its bottom to support the door along its bottom edge and means to grasp a door along its lateral opposed sides;
• means to move said fist frame upward and downward relative to said second frame and mobile frame, lever rod means to lever said second frame forward and rearward, whereby a door may be placed and grasped on said first frame and moved on the mobile frame to a doorway and said second frame upon being levered forward to lever said first frame forward to place the door a proper upright position in the doorway and means to raise the first frame may be operated to raise the first frame and door thereon to a proper height in the doorway for attachment of the door to the doorway while in said upright position in the doorway.

A door attaching apparatus for supporting a door having a bottom edge and lateral opposing sides comprising a mobile frame adapted to be rolled along a surface, a upward extending first frame having lateral sides and a bottom and a top, a flange along the bottom to receive a door along its bottom edge, lateral telescoping rods intermediate the height of the first frame and spring urged to telescope laterally toward one another to grasp the lateral opposing sides of the door, said rod having hooked outer ends to grasp the door along its lateral edges when the door bottom edge rest upon the bottom flange of the first frame, elevating mechanism on the mobile frame to elevate the first frame relative to the mobile frame to raise and lower the first frame relative to the surface to place the door at a proper height for installation of the door in a doorway;

• adjustment means connecting the first frame to the mobile frame to rotate the first frame in the plane of the first frame and door thereon relative to the mobile frame to adjust the angular relation of the door to the doorway, forward and rearward adjustment means on the mobile frame to adjust the first frame and door thereon in a plane perpendicular to the plane of the first frame.
