DOOR-HANGER.

SPECIFICATION forming part of Letters Patent-No. 434,651, dated August 19, 1890.

Application filed February 28,1890. Serial No. 342,092. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM BARRY, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Door-Hangers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

Thisinvention pertains to the class of doorhangers which carry the door suspended from an overhead double track and have the carrying-wheel connected to the hanger-frame so as to oscillate vertically but independently of each other, and thus adapted to accommodate themselves to any unevenness that may exist in the tracks. I

The object of the invention isto facilitate the attachment of the hanger to the door, and also to reduce to a minimum the lathe-work required in the construction of the doorhanger and render the same more reliable and efficient in its operation; and to that end the invention consists in the improved construction and combination of parts, as hereinafter fully described, and set forth in the claims.

In the annexed drawings, Figure 1 is a side elevation of a door-hanger embodying my invention, the front wheel being omitted to better illustrate the construction of the hangerframe. Fig. 2 is an end View of the doorhanger. Fig. 3 is a top plan view of the hanger-frame with its attachments indicated by dotted line. Figs. 4 and 5 are detached perspective views of the rock-arms. Fig. 6 is a detached perspective view of the equalizing-lever; and Fig. 7 is an enlarged longitudinal section of the journal of one of the wheels, showing the attachment of said wheel.

Similar letters of reference indicate corresponding parts.

A represents the door-plate, which is secured to the top edge of the door by means of screws passing vertically through said plate and into the door. To facilitate the attachment of this plate, I provide the under side thereof with Spurs 8 s and form the top of the plate with a central stiffening-rib r and with striking-hubs s s on said rib over the aforesaid spurs. In securing the said plate to the go door theplate is placed in its requisite position,

plate and forward from the front end thereof.

To these hooks is connected the hanger-frame B, which consists of a metal plate disposed vertically and lengthwise of the door-plate A, and is formed at its rear end with a loop g, through which the inner hook A passes, and thus couples said end of the hanger-frame to the door-plate in such a manner as to allow the frame B to oscillate vertically on the plate A.

The outer end of the hanger frame is formed with a horizontal transverse aperture 2' and with a vertical perforation intersecting said aperture, and is adj ustably connected to the door-plate A by means of a separate loop Z, receiving through it the outer hook A and formed with a vertically-perforated outward offset Z, for the reception of the couplingbolt in, which is inserted from the under side of said oifset and provided with a suitable head thereat for turning the bolt either by a screw-driver or wrench. The nut N of said bolt is seated in the aperture 2', in which it is held from turning while turning the bolt in said nut. To properly sustain the loop Z at its requisite angle in relation to the door-plate,

I form the rib r with shoulders h h on opposite sides of the fixed end of the hook A, against which shoulders the loop Z rests by its inner side.

The object of the detached connection of the loop lto the outwardly-proj ecting hook A is to facilitate the operation of hanging the door, which is readily effected by placing the door in its requisite position under the tracks D D. The plate A having previously been secured to the top of the door and the hanger being mounted on the aforesaid tracks, the

rear end of the hanger is easily slipped onto 5 the rear hook A of the plate A, and then the loop Z, which is connected to the outer end of the hanger-frame by the coupling-bolt K, can be slipped onto the outerhook A to connect the outer end of the hanger to the door-plate A, which latter connection is then ad just-ed to carry the door at the proper distance from the floor by turning the coupling-bolt K.

a and 1) denote two rock-arms pivoted to opposite sides of the hanger-frame, as hereinafter described. The inner end of the rockarm a is formed with a bifurcation a, and the same end of the other rock-arm b is formed with an extension I) beyond the end of the rock-arm a and terminating with a hook 0. Between the said ends of the two rock-arms is an equalizing-lever d, pivoted eccentrically in relation to its length to the hanger-frame B and engagingby its outer end the bifurcation a of the rock-arm a, and having its inner end inserted into the hook c of the rock-arm 'b, and retained in said hook by means of lips c 0, formed on the lever 01 and engaging opposite sides of the hook end of the rock-arm b.

To brace the rock-arms laterally, I form the top portions thereof with segments ff concentric with the pivot-s of the rock-arms and projectinglaterallyover the top of the hangerframe, so as to cause the two segments to bear against each other, the bottom portions of the rock-arms being sustained laterally by their bearing on the sides of the hangerframe.

To limit the oscillations of the equalizinglever (1 so as to maintain the same in its engagements with the rock-arms, as before described, I provide the hanger-frame with projections or stops 1) p at opposite sides of the fulcrum of said lever.

In order to impart maximum stability and durability to the doonhanger, I connect the rock-arms a and b and the lever d to the hanger-frame by means of tubular trunnions ttand t, formed integral with the hangerframe B. The trunnions 1ft are axiallyin line with each other, and the rock-arms a b are formed with circular eyes encompassing said trunnions, and the lever d is mounted in the same manner on the trunnion t. On the ends of the trunnions are placed washers 0 0 of suflicient diameter to retain the rook-arms and lever 011 their respective trunnions, the washers being secured to the trunnions by means of bolts or rivets passing through the washer and through the axial channels of the trunnions. It will thus be observed that said bolts or rivets are entirely relieved from friction of the rock-arms and lever and from the weight of the suspended door.

R R represent the door-carrying wheels by which the door is suspended from the two track-rails D D, upon which latter the wheels travelin opening and closing the door. These wheels are pivoted to the rock-arms at corresponding ends and equidistant from the fulcrums thereof and preferably on trunnions e e, formed integral with the outer or free ends of the rock-arms a b, and are retained thereon by bolts 9, passing through washers w on the free ends of the trunnions and through axial channels a in the trunnions and pro vided with heads on their outer ends and with nuts 11 on their inner ends. The adjacent sides of the rock-arms are formed with square sockets U, in which the nuts or are seated, and thus countersun ken and prevented from turn ing.

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

1. The combination, with the hanger-frame, of vertically-oscillatory rock-arms pivoted to said frame, wheels pivoted to said rock-arms at corresponding ends, and a lever pivoted to the frame and engaging the opposite end of the rock-arms to equalize the oscillations of said rock-arms in opposite directions from each other, as set forth.
