DOOR-HANGER FOR SLIDABLE DOORS.

No. 807,429. Specification of Letters Patent. Patented. Dec. 19, 1905. Applicati n fi fi $eptember 28, 1904. $erial1lo. 226.321. T01 aZZ whom it may concern.- inner face of the hanger,thus giving suflicient play for the short vertical guide-flange of the trackwhen the door is being opened or closed. This track or rail upon which the hangers travel consists of an L-shaped support having a vertical flange 12, provided with perfo rations to receive bolts by which the same is secured to the side of the car or buildings, and at right angles to this flange is the horizontal rail portion w, upon which the upper roller travels,while the under side of this portion w provides a way for the lower roller to bear against and travel on when the door is being opened or closed or being tilted or thrown out of its vertical line, thereby preventing said door from holding or binding, which is the case with all doors hung from the top. It will be observed from the above description, when taken in connection with the annexed drawings, that our main object in constructing this door-hanger is to provide means whereby it is impossible for the door to bind or become stuck when thrown back in opening or when being closed. To accomplish this, we have provided the second or lower roller, which is used in combination with the upper and larger roller, and when the door is being opened or closed the upper roller bears the weight of the same and travels upon the upper face of the track and is guided by the short vertical flange of the L- shaped rail or track, and should the door be thrown upward or out of a vertical line when being opened or closed the lower roller comes into play, the same engaging the under side of Be it known that we, Amos 0. BANKS and GEORGE E. BANKS, citizens of the United States, residing at Baltimore city, State of Maryland, have invented new and useful Im provements in Door-Hangers for Slidable Doors, of which the following is a specification.

This invention has relation to improvements in door-hangers for slidable doors; and it consists in the novel construction, combination, and arrangement of the same, all as will be hereinafter described, andparticularly pointed out in the appended claim.

The annexed drawings, to which reference which Figure 1 represents a front view of a freightcar door showing our device applied thereto. Fig. 2 is a vertical detail transverse sectional view of the same. Fig. 3 is an end view of the L-shaped track or rail upon which the hangers travel. Fig. 4 is a rear view of one of the hangers. Fig. 5 is a face view of one of the guide-blocks, and Fig. 6 is an edge view of the same, and Fig. 7 is a vertical sectional view of the hanger.

Referring by letter to the accompanying drawings, A designates our hanger attached to a freight-car door, provided with the perforations a to rece've the bolts 1), by which said hanger is secured to the upper portion of the door 0. At the upper end of the hanger and upon the rear face thereof is a housing or frame (1, within which is arranged and pivotally supported the large roller 6, and below the track, traveling thereon and preventing this frame is an angular support f, between any binding of the door. Again, it will be the vertical portion gof which and the hanger seen that the two rollers are independent of each other in their movements upon the track, and the slotted bearings for the journals of .the rollers permit a free vertical play to the hanger. At the same time the rollers can be readily placed in position in the hanger or removed therefrom through the open ends of the bearings on the an ular plateand inner plate of the top frame 0 the hanger. Also it will be observed that this angular offset or plate provides, in connection with the vertical hanger or body, a square shoulder 17;, which fits snugly upon the top of the door and serves, in connection with the bolts passing through the hanger, to secure the latter firmly in position on the door. The track above the door on which the hangers travel terminates at the points y y, leaving spaces or openings 2 2 between the opposite ends of is arranged and journaled the small roller h. This angular lug or plate is provided with a bearing i, which is open at the top, as at j, and the inner horizontal plate is of the top frame (1 is also provided with a bearing Z, the lower portion m being open, as clearly shown in Fig. 4 of the drawings.

Opposite to the bearings above described are upper and lower bearings n and 0, the same being at opposite ends of a vertical slot 19, formed in the hanger at the upper portion thereof. The rollers e and h are provided with the journals 4" and s, which engage the bearings, said journals, the hubs tit, and the rollers being formed integral. The hubs t of the rollers are shorter than the hubs a, this construction being designed to throw the tread of said rollers inwardly and OH from the the rail and the end blocks a a, secured to the side of the car, whereby the rollers can be readily inserted in placing them upon the track. A face-board b is secured to each end block a, thus, in connection with the extension 'of the roof of a car, providing a housing for the protection of the track and hangers, with their rollers, against snow, rain, and ice.

0 0 represent angular guide-brackets that are secured by bolts to the side of the'car and below the dooropening, said brackets being designed to guide and hold the door in position, the edges cl being curved outward, while the horizontal portion or floor e of the offset curves downward, thus giving a flaring mouth or inlet for the door both at the side of the brackets and the floor 6, thereby guiding the door therein when being opened or closed, and a stOp-bracketf is secured to the car for limiting or stopping the door when thrown backward, and a device as'herein described is durable, not liable to get out of order, and at the same time cheap to manufacture.

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

In a device of the character described, an L-shaped tracksecured to the side of the car above the opening therein and formed with a vertical flange along its outer edge,- a door slidab'ly mounted parallel with the face of the car, hangers secured to the outer face of the door and extending above the upper end thereof and formed with inwardly-extendinghousings at their upper end portions surrounding the rollers therein and having open-slot bear= ings in their inner walls and a vertical slot in the upwardlyextending portion of the hanger, an inwardly extending bracket formed on the stem of the hanger'below the track and having a vertical'flange at the inner side formed with an open-slot bearing rollers AMOS o.
