BOX-GAB-DGOR HANGER.

Specification of Letters Patent.

Patented Nov. 15, 11%21.

To (all whom it may concern Be it known that 1, CLAUDE HAnMoN EN- m'oo'r'r, a citizen of the United States oi Anierica, residing at Bayard, in the county of Morrill and State of Nebraska, have invented new and useful Improv ments in Box-Car-Door Hangers, oi which the following is a specification.

The object of the invention is to provide a hanger for the doors of box cars and the like, which are ordinarily mounted for sliding movement whereby the binding or sticking of the door in the guides due to the swelling thereof or the warping of the door or guides which involves diiiiculty in the movement thereof, may be avoided, it being a well known fact that owing to such inefiective mounting of doors of this type it is the common practice for those who have 00- casion to open the same to employ a crow bar or like implement with the result that the doors and frames are more or less damaged and frequent repair is necessary in order that the stock may be kept up to the required standard for the safe shipment of goods and therefore it is a particular object of the invention to provide a form of door hanger whereby the strain applied thereby in the friction incident to movement of the door within its guides will effect a loosening of the door in its guides to compensate for any extension of the door or relative warping of the door or its guide means; and with these objects in view, the invention consists in a construction and combination of parts, of which a preferred embodiment is shown in the accompanying drawing, wherein:

Figure 1, is an elevation of a door provided with hangers embodying the invention applied in the operative position to a box car.

Fig. 2, is a detail vertical section of the upper portion of the door and frame on the plane indicated by the line 2-2 of Fig. 1, showing the hanger in elevation.

Fig. 3 is a similar View showing the hanger in section.

Fig. l, is a vertical section on the plane indicated by the line 4-4: of Fig. 3.

Fig. 5, is a cletail transverse sectional view of the lower edge of the door and track.

Fig. 6, is a longitudinal elevational view of a portion of the hanger guide.

Fig. 7 is a transverse sectional view of the hanger guide.

In the construction illustrated, the hanger of which two or more may be employed at the upper edge of the door indicated at 10 embodies a stirrup 11 having side plates adapted to be applied by bolts or rivets to I the door and a traveler 12 having forwardly and rearwardly extending arms 13 upon 0pposite sides of the extremities of which are mounted rollers 14: for traversing tracks 15 formed in a box guide 16 secured by outer and inner brackets 17 and 18 to the side wall or frame of the car as indicated at 19. The stirrup 11 is provided with a loop 20 which is connected with a traveler by means of a pendent link 21 capable of swinging movement in the plane of the door 10, under such conditions that when door opening pressure is applied for example in the direction indicated by the arrow in Fig. l to the edge of the door any resistance which may be offered by the travelers in the guide 16 will be compensated for by the forward swinging movement of the links 21 which will raise the lower edge of the door and thus tend to release the travclers while at the same time any pressure on the lower edge of the door in the bottom guide 22 will be relieved to allow the door to move freely in the desired direc-' tion.

In the construction illustrated, the lower guide 22 is provided with a series of transverse rollers 23 mounted therein for contact with the lower edge out the door, the sides of the guide being extended above the plane of said rollers to hold the lower edge of the door against swinging movement toward an d from the plane of the side wall of the car.

In other words, with a construction such as that illustrated above pressure applied in the required direction to the door serves to relieve the frictional engagement of the lower edge of the door in its guide and at the same time to apply pressure directly to the travelers on lines respectively parallel with the guide in which they are mounted so that any tendency of the door to stick will be relieved and the necessity for the use of a crow bar or other means of applying leverage to the door is obviated.

The invention having been described, what is claimed as new and useful is A door hanger having a stirrup attached to the upper edge of the door, the said stirsaid stirrup, the link having a substantial rup being formed With a loop, a, traveler for movement longitudinally of the traveler and movement on a track consisting'of a member also having a substantial movement'in the 10 shaped to provide forwardly and rearvvardly loop of the stirrup. 7
