DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 394,853, dated December 18, 1888.

Application filed February 14, 1888. Serial No. 264,004. (No model.)

To aZZ whom it may concern.-

Be it known that we, JOHN CLAYTON HAL- DEMAN and EPHRAIM A. HALDEMAN, citizens of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Door-Hangers, which improvement is fully set forth in the following specification and accompanying drawings.

Our invention relates to door-hangers, and

more especially a door-hanger capable of application to sliding doors.

The object of ourinvention is the provision of a door-hanger which will practically hang I 5 the door in such a manner that it can be slid in opposite directions or opened and closed with ease, and by which sagging of the door is entirely overcome.

To attain this object, the invention consists of a system of levers and arms pivotally secured together and to the door or to a fixed object or frame, so as to cause the door to be always moved in the same plane, the said system of levers being composed of two sets 2 5 of levers and arms corresponding in number and length, each set being separatelysecured to the door and to the fixed object or frame and the sets being connected by arms, which are connected to a lever pivoted to the frame.

In order that the construction, operation, and mlvantages of our invention may be understood, we have illustrated an embodiment of the same in the accompanying drawings, in which 3 5 Figure 1 represents an end view of a door with our improved hanger applied thereto.

Fig. 2 represents a front elevation of the hanger applied to a door. Fig. 3 represents a front elevation of a hanger in the position it assumes when the door is closed and in dotted lines the position when open.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates one set of levers, and B designates the other set, which we have so designated for the sake of convenience, the two sets of levers corresponding in the number and lengths of its levers, as herein set forth.

The set A is composed of the long arms 1 and 2, of equal length, which are pivoted together at their upper ends, and said upper ends are also pivoted to the plate C, which is secured to afixed object. The long arms 1 2 diverge, and are attached at bottom to the short arms 3 4, of equal length, the lower ends of said short arms being pivoted together and to a baseplate, D, rigidly secured to the door or other object to be moved.

The setB is composed of the long arms 5 and 6, of equal length, pivoted together at their upper ends to the plate 0 and at their lower diverged ends to the short arms 7 and 8, which latter are of equal length, and are pivotally secured at their lower ends to the base-plate D below the pivotal point of the short arms in set A.

The long and short arms respectively of the two sets of levers are of corresponding length, and the distance apart respectively of their connections with the fixed frame and door are equal.

From this construction it will be observed that the two sets of levers have their long and short arms respectively parallel with each other, and to cause the arms to move simultaneously and parallel with each other at all times we connect them as hereinafter fully described.

To the short arms of the sets of levers A and B are pivoted the arms 9 and 10, of equal length, also pivotally connected at their upper ends with the arms 11 and 12, which arms 11 and 12 are of the same length as arms 3 and l, and have their upper ends pivoted to the lower end of the arm 13, the upper end of this arm being pivotally secured to the plate C. This arm 13 is of the same length as each of the arms 9 and 10, and the distance between the respective upper and lower connections of the sets A and B with the fixed object and the base-plate D.

By connecting the arms as described, it will be observed that the points of attachment to the door and fixed object are never changed, which permits the door to be moved or slid back and forth with ease and in the same plane, the limit of extent of its motion in either direction being reached when the long and the shortarms of either set of lovers are in a straight line.

By using the system of levers and arms as ierein set forth, it will be noticed that the door has a double support or connection. with the frame, so that the liability of the door to sag and thereby to work hard or stick is prevented, and owing to its pivotal connection it is enabled to be maintained in a vertical plane while being moved in a horizontal direction. A I

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The door-hanger herein described, consisting of two sets of levers, each set having two long arms of equal length and two short arms of equal length, two arms of equal length connecting said sets of levers, aml an arm pivotally connected to two short arms, the latter of equal length with the short arms of the sets of levers, and connected to one or the sets of levers, said parts being eombined substantially as described.

2. A door-hanger consisting of the set ol. levers A, composed of the pivotally-eonneeted 1 equal long arms 1 and 2 and the equal short arms 3 and l, the pivotally-eonnecte(l set ol. levers I3, eorres ionding in number and length to the set of levers A, the arms 5) and 10, of equal length, pivotally connected to both sets of levers A and B, and the arm 13, pivotally connected to arms 11. and 12, of equal length with the short arms of the sets of levers, and pivotally connected to one ol said sets, said parts being combined substantiall; as de-
