Sheet-Metal Hinges.
UNITEIJY STATES PATENT DFFIGE.
WILLIAM H. HART, OF NEW BRITAIN, CONNECTICUT. i
-IMPRVEMENT IN SHEET-METAL HINGES.
-Speciication forming part of Letters Patent No. 139,464, dated June 3, 1873; application filed May 13, 1873.
To all whom 'it may concer-n:
Be it known that I, WILLIAM H. HART, of New Britain, in the county of Hartford and State of Connecticut, have invented a new and Improved Sheet-Metal Hinge, of which the following is a specilication:
In my improved hinge the portion or portions which have to be removed from the hub of one leaf toy make room for the hub of its fellow are bent out, instead of out away, and form a rigid arm, standing at about right angles to the leaf', as hereafter described.
My improvement is designed for that class of hinges, the leaves of which rest upon the dat surface of the door and wall, and which are usually termed strap and T-hinges, in cnntradistinction to that class in which the leaves rest upon the edges of the door and siding.
ln the accompanying drawing Figure lis a rear eleva-tion of a T-hinge, which embodies my invention. Fig.2 is a top or edge view of the same; and Fig. 3 is a permake them by simply slitting the ends of theleaf and then bending a portion or portions.
into a coil to form the hub, as in the ordinary sheet-metal hinge, and bending out the arm B from the portion or portions which have to be removed to make room for the coil or hub of the opposite leaf, and which portion is cut out and wasted in the ordinary sheet-metal pends merely uponv Whether one or more por` tions of the hub are to be removed to make room for its fellow, for if the arm is bent from n a hub, in which only one portion is removed, as in Figs. l and 2, there will be but one arm to bend out, but if it is bent from the opposite hub ot' a strap-hinge,in-which twoportions of the ,hub are removed, as in Fig. 3,1two arms may be bent out.
The object of my invention is to produce a hinge which, without increasing its size Vand the stock from which it is made, may be secured in place with extra firmness, and I produce this superior hinge with but little, if any, additional cost. y
I claim as my inventioni y As a new article of manufacture the` 'strap or T-hinge, herein shown and described, in which the portion or portions which have to be removed from the hub of one sheet-metal leaf, in order to make room for the hub of its fellow, are bent out instead of cut away, and form a rigid arm, B, standing at about right angles to the leaf, substantially as and for the purpose set forth.
