UNITED sTATEs PATENT oEEioE.
JOHN BROUGHTON, OF CHICAGO, ILLINOIS.
Doon-SPRING.
Specification of Letters Patent No. 15,555, dated August 19, 1856.
To all whom it may concern:
Be it known that I, J oHN BRoUGHToN, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Door-Spring; and I do hereby declare vthat the following is a full, clear, and exact description of the same, reference being had `to the accompanyingdrawings, forming part of this specification, in whichj Figure 1, is a horizontal section of a door and jamb with my improved spring arrangement applied to them. This view shows the position of the parts when the door is closed. Fig. 2, is a similar section, showing the position of the parts 'when the door is opened so as to stand at right angles to the face line of the amb and wall. Fig. 3, is also a similar section showing the po sition ofthe parts when the door is opened so asto stand with its face parallel with the face line of the jamb and wall. Fig. 4, is an edge view of the door detached from the jamb, and having one half of the arrange- \ment, forming the spring, attached to it.
Fig.` 5, is a vertical section of the same through the line ae, a, in Fig. 4.
Similar letters of reference indicate corresponding parts in the several figures.
The nature of my improvement consists in a novel arrangement, hereinafter specified, to be applied in connection with a door for the purpose of rendering it self-closing; said arrangement combining great simplicity and durability and when on the door, and the door closed, being invisible.
` To enable others skilled in the art to make' and use my invention, I will proceed to describe its construction and operation.
A represents a portion of a door and B a portion of a door jamb. The door A, is hinged as at 0;, to the j amb in the ordinary manner.
O, is an additional butt hinge; its leaves are counter sunk, so as to fold flush with the door jamb, in metal face plates o, b, which are to be tted in the edge of the door and jamb as shown. This hinge folds and unfolds the reverse of those a, and stands in close relation to the lower one of 4springs are attached fast to the backside ofA the metal face plates o, b, and the lower Vend of the same hangs loosely and is connected to the leaves of the hinge by a thin elastic tug f, which is attached by a fulcrum pin or screw L, to the lower end of the springs and passed from the same to and behind the quadrantal projection of the leaves and then `fastened to the same by screws ori otherwise, as desired.
The parts thus arranged are adjusted to the door and jamb and confined and held in place by the face plates which are screwed firmly to the door and jamb, as shown.
Operation: By opening the door, the leaves of the hinge C, are caused to unfold in the manner illustrated in Figs. 2 and 3, and consequently the quadrantal projections are turned so as to cause the thin elastic tugs to coil around them and thereby to `become shortened and consequently to draw the end of each of the springs toward the edge of the door and jamb and thus bring the springs into action and cause them to exert a powerful strain upon the leaves of the hinge, and when the door is set free ause them to fold together and close the oor.A
