To all whom it may concern'

Be it known that I, John R. MacDonald, citizen, of' the United States, residing at The ends of ηίπΤ . WSiSzds usetu 1 Improvements in Hinges, of which the following is a specification. _{JU£rs aq at}

My invention relates to an improved type the leaf 4 of hinge m which, the leaves are detachable have ^{10 se}P^arable- While the hinge is capable of general use, yet one particular need therefor is in connection with screen doors, since one’ If^aBaclled. to the door and the °ther leaf to the casing and the door re15 moved for winter storage with one leaf attached thereto and without necessitating the removal of the other leaf from the casing Jr ^inventl°^{n res}i^des in the details of con9 λ + ^combination and arrangement of 0 the parts as will now be described with relation to accompanying drawings, wherein ^οηθ Preferred embodiment is shown.
