AN EXTRA THAT PAYS

In general building practice, only the heavier doors in a house are hung with three hinges. For all lighter doors, two hinges are generally considered to be sufficient. The provision of three hinges for every door is, however, a minor extra well worth paying lor when a house is bein '- built or. when a door that has given trouble is being re-bung. The third hinge serves a valuable purpose in holding the edge of the door in alignment and providing a safeguard against warping. It often serves, also, to prevent the middle part of the door fouling the stop on the hinge side of the frame, a trouble not uncommonly met with when the timber used in doors or frames has been imperfectly seasoned. If a door is hung on two hinges only, each hinge carries one-half of the weight of the door. When the door is hung with three hinges, each' of these carries only about one-third of the weight, thereby deereasing the strain and wear and tear. More screws are driven into the door jamb and the door, thus relieving the strain on individual screws and on the wood that holds them. Lock troubles, also, are less liable to arise when a door is firmly held in place by three hinges. .
