An adjustable hinge for pivotally mounting a door on a frame has a first leaf mounted and an adjustable mounting assembly to be mounted on the frame or the door. The mounting assembly includes (i) a bracket, (ii) a vertically extending threaded shaft, (iii) an internally threaded pinion gear, and (iv) a rotatable screw. The threaded shaft is fixed on the bracket and threadably engaged with the pinion gear. The rotatable screw has a threaded outer surface portion engaged with the pinion gear for rotating the pinion gear relative to the shaft so as to axially move the gear relative to the shaft. A second leaf is pivotally mounted on the mounting assembly and has one end pivotally engaged with the first leaf. A horizontally extending adjusting screw has a shank threadably engaged in the second leaf, and the end of the shank abuts the bracket so that the rotation of the adjusting screw pivots the second leaf inwardly and outwardly relative to the bracket. The pinion gear abuts a surface on the second leaf so that the rotation of the pinion gear by the rotatable means moves the second leaf vertically relative to the bracket.
