Abstract: A vacuum cleaner having a floor traveling head with wheels and an elongate handle pivotably connected to the head. The head has two motors; one connected to an impeller and one connected to a rotatable brush. The head has rechargeable batteries therein for supplying electricity to the motors and a three position electrical switch. All working components of the vacuum cleaner, including an air filter and dust/dirt collection cup, are in the floor traveling head. The handle has no working components thereon.

Abstract: 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.
