HANGING DOOR.

SPECIFICATION forming part of Letters Patent No. 314,005, dated IVIarch 17,1885.

Application filed October 20. 1884. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES W. EMERSON, a citizen of the United States, residing at Charlestown, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Hanging Doors, of which the f'ollowing is a specification.

My invention relates to an improvement in that class of doors which are sus )ended from bearings above the doors,` withgpeeial refer,- ence to Patent No. 295,743, granted to me March 25, 188i.

The object of the invention is' to provide a means whereby the doors may be easily opened and closed, and also an improved means for remedying the sagging of the doors, and also to accommodate the door to any settling of the sill or floor. rIhe invention is equally applicable to outside and inside doors of buildings, and also to railroad freight-cars.

The invention consists in certain details of construction and arrangements of part-s, more fully hereinafter set forth.

Referring to the accompanying drawings, Figure l represents a door with my invention applied. Fig. 2 is a vertical section of the same. Fig. 3 is a cross-section ou line y y of Fig. 1. Figs, 4 to 6 are details of the hanging connections enla'rged. iFig. 7is a modification of Fig. 6. views in detail of the adjustihg device.

A represents the side of aroom or building, or it may be a freight railroad-sar, 'and A is vaportion of the doorway, `the door 13 being partially open.

C is a beam or bar secured to the wall or frame above the door. It is made' with a central longitudinal tongue or projection, asindicated in cross-section in Fig. 2.` D D are rollers or wheels, composed of side flanges and a central axis or groove, as shown in Fig. 2, so as to ride or roll upon the rail or beam C, the iianges being guided by the projection on beam C.

F F are two bars, in each of which are mounted two rollers or wheels, D D, the axes of the rollers or wheels'passing through holes in said bars. The bars are made iu two parts,

the one resting on the other,and the two firmly secured together, as indicated in Figs. l and 5.

Above the Wheels D, and resting upon the flanges of the same, is bar or' beam E, having Figs.` S and 9; are enlargeda longitudinal tongue or projection, c, on the under side, as shown in Fig. ei, the said projection passing between the iianges of wheels D.

To the bar E are attached metal straps or hangers G G, of the form shown in Fig. 4, the upper end bei ne; bent over the top of the bar Fi.

To the outsidel edge of the door B, at the upper end, are secured plates or brackets II H, provided with ears t' i, th rough which pass rods l I. having in Fig. G the upper end bent at a right angle and surmounted by a knob or head, l1. rIhe upper ends of the rods I I are fitted in the notches g g in the lower bent ends ofthe hangers GG. This arrangement admits of the door being swung in and out of its opening, as indicated in Fig. 3, so that when the door is closed its outer face will be iiush with the side of the wall or framing. rIhe side edges of the door are bevcled,and are made to fit snug ly in thc beveled edges of the frame, as shown in Fig. 3. This arrangement is particularly adapted to railroad freight-cars. The rod in Fig. 7 is made straight for use on doors that are not intended to be closed within the openlng.

In order to remedy the sagging of the door, and also to adapt it to any settling of the sill or floor, I have made the lower ends of the rods I I screw-threaded, the screw-threaded portion passing freely through the lower ear, i, of bracket H, the said ear resting upon a thumb-nut, I?, on the screw-threaded portion of the rod I, so that by turning thennts P the door may be adjusted upward or downward, as required. An additional means of adjusting the door is shown in Figs. S and 9.

L Larc metal blocks designed to be inserted within the upper edges of the door. The blocks are made thicker at their lower ends,

which parts come in Contact with eachother,

leaving a recess in the parts above, as shown in Fig. 8. Vithin this recess is iitted so as to slide freely a plate` K, having a vertical slot at its center, as shown in Fig. 9, and a head, O, by which it can be raised orlowered.

A bolt or bar, M, passes into the door andthrough holes in the lower parts ofthe blocks L L, by means of which the latter are held firmly in place. The upper parts oft-he blocks L L and the plate K are held together by a screw, NL Vhenit is desired to raise or lower the door B, the screw N is withdrawn suffiroo si. if,

ciently to allhw the central bar, K, to be raised 0r lowered "r the door to be moved up or i "":iredr'lland lwhen in the right poeW Nil is tightened up and the part-s again i rmly held together.

lIt will be seen that the vertical edges of the door are beveled, as shown at b b, Fig. 3, to

iit Within corresponding beveled sides, a a, of the doorway when the face of the door is made to close flush with the sides of the wall `shown and described.

2. The combination, with the door B, beveled on both vertical edges, of the hangers G and swivel-rod I h, whereby the beveled edges of the door are caused to fit in the beveled sides a ct of the doorway when closed, and swing ont ofthe saine when opened.

3. The combination, with the door I3, ofthe adjusting device P i and the swivel-rod I 7z,as and for the purpose set forth.

4. The combination, With the door B, ofthe hangers G, bar E, groovcd rollers D, the bars F, each made in two parts longitudinally, and the bar C, provided with atongue, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
