DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 245,605, dated August 16, 1881.

Application filed May 16, 1881. (No model.)

To all whom it may concern.-

Be it known that I, CALEB BRINTON, of Ohica-go, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Door-Hangers, of which the following, in connection with the accompanying drawings, is a specification.

In the drawings, Figure 1 is a side elevation of a door-hanger embodying my improvements. Fig. 2 is an edge view of the same closed. Fig. 3 is a side elevation showing a modification in the construction of the hanger. Fig. 4 is a detail, in perspective, of the hinge and guidestrip. Fig. 5 is a section in the plane of the line at w of Fig. 4, and Fig. 6 is an end view of one of the levers.

Like letters of reference indicate like parts.

A and A represent bars, arms, or levers, arranged parallel, one end of each of which is hinged to the rear edge of the door B, as indicated at a, or in any suitable way admitting of the other ends of the said levers being moved or swung vertically. 0 and c are also parallel and vertically-swingin g levers, and these are hinged to a stud or post, D, of the building to the rear of the door. The levers A and 0 meet each other, and are pivoted together in such a way as to permit the vertical movement already referred to. The lever c is provided with a roller, E, which lever, includin g its roller, is about twice the length of either of the other levers, so as to allow the roller E to lie on or against the rear edge of the door. The lever A meets the central post of the lever 0, and is there pivoted to it. The levers A, A, and c are of equal length, which levers, including lever c, are joined to the ends of the vertical central guide-bar, F, at the point where these levers are respectively pivoted to each other.

It will be perceived from the foregoing description that the door will be suspended by the hanger, and may be moved horizontally or parallel to the floor in opening or closing it. The guide-bar F causes the upper and lower sets of levers to move together, and, in conjunction with lever c, prevents the door from tilting and sagging. The joints connecting the levers to each other and to the guide-bar should stand above or below the other joints when the door is open, to avoid a dead-center.

lieving the hangers from too great weight and strain. In this arrangement the spring 0 is omitted, as the friction of the roller E upon the floor overcomes the tendency of the hangers to move the door, as hereinafter explained. The rear edge of the door may pass thepost T.

The object of the roller E is simply to lessen friction, which would result from pressure of the lever 0 directly against the edge of the door or other post. This object is further accomplished by the employment of a guide or way, b, for said roller to travel upon. When the track I) is employed it may be bowed or curved, causing the door to describe the arc of a circle, thereby permitting the door, when closed, to fit snug to its frame at either the top or bottom of the door, according tothe direction of the curve, without the door being obstructed in its movements. When only one roller, E, is employed, it may be arranged to operate in either the upper or lower set of levcrs.

G G are the hinge-plates which are applied to the door-post or building. These plates have deep notches O O, which are rabbeted or recessed, as shown in Fig. 5, to receive the stem and head of a headed pin or stud, so that said pin or stud can be removed from the plate only by being moved out of the open end of said notches. H is a strip attached to the wall or studding, and having in its face a groove or way, d. This strip leads from the doorway to the notch G. The longest part of plateG closes the end of the groove (1, as shown in Fig. 4.

I I are headed pins or studs on the inner ends of levers c and c.

To adjust the hanger to the hinges G Gin a hollow wall, the studs I I are placed in the forward ends of the grooves d d, and are then forced back into the notchesOC. The weight of the door upon the hanger serves to keep the studs I I in the notches O C. By this means the hanger and door can be attached to or detached from its hinges in the recess between walls after said'walls are finished.

In order to conveniently remove the door and hanger from between finished walls, I also employ a button or buffer, J, which is pivoted horizontally to the rear edge of the door. The ends of said buffer are intercepted by projections provided between the walls, thus limiting the movement of the door and hanger. Said bufl'er can be turned to a vertical position by inserting a thin instrument between the door and its frame, when the door can be moved from between walls, thus enabling repairs to be conveniently made.

In the lower end of the door there is a groove running the entire width of the door, in which the guide 1' operates to keep the door in a vertical position and prevent it from rubbing against its frame. A similar guide and groove may also be employed at the top of the door.

It is obvious that the gravitation or weight of the hanger will tend to push and hold the door either open or closed, according to the position of the hanger. To overcome this tendency I apply a bracket, 0, to the rear edge of the door, through which bracket I pass a bolt, 0, which is yoked at its lower end to the spindle of the roller E.

Between the bracket 0 and the upper or threaded end of the bolt 0, I arrange an open spiral spring, 0, which spring is held in place and its tension regulated by means of the screwnut h. It will now be perceived that as the hanger tends to move the door this tendency will be overcome by the spring 6.

It is obvious that other means may be employed to perform the function of the spring, and when it is desired to have the hanger close doors or gates this spring, or its equivalent, may be dispensed with advantageously.

The screw-holes in the door-hinges may be slotted to facilitate the vertical adjustment of the door, as indicated'at f j.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a door-hanger, ofan upper and lower set or series of extensible and retractible jointed or pivoted levers and a vertical central guide rod or bar, F, jointed or pivoted to each of the said series, substantially as and for the purposes set forth.

2. In a door-hanger consisting of an upper and lower set or series of extensible and retractible jointed or pivoted levers, the extended lever 0, having a free or loose end, carrying an anti-friction roller, E, substantially as and for the purposes specified.

3. The combination, in a door-hanger consisting of an upper and lower set or series of extensible and retractible jointed or pivoted levers, of the vertical central guide rod or bar,

F, jointed or pivoted to both the said sets, the lever 0, having afree or loose end, and the roller E, mounted on the free or loose end of the lever 0.

4. The combination, in adoor-hanger, of the notched and rabbeted hinge plate G, the grooved guide H, and the extensible and retractible levers carrying the headed pins or studs I, adapted to travel in the said guide and to enter the said plate, substantially as and for the purposes specified.

5. The combination of the bracket 0, rod 0, spring a, and the extensible and retractible levers of a door-hanger, substantially as and for the purposes specified.
