QAR DOQR HANGER.

Application filed December 1, 1922 Serial No. 604,134.

TOIQZZ whom it may concern:

Be it known that I, Tnnono-nn R. CHAND- men, a citizen of the United States, residing at Davenportpin the county of Scott and State-of Iowa, have invented a new and useful Car-Door Hanger, of whichfthe following is a specification. i

This invention relates to improvements in sliding doors and more particularly to hangers/for mounting a door on one side of a ca rlor the like'which permit the door to be moved to open or closed position and p re-. ventthedoor' from being detached and lost while the car is in transit.

Hangers for car doors have been constructed to movelaterally and longitudinally on a track but such devices a e of complicatedpeicpensive construction, easily liable to get out of order and dependent upon inanual' operation to force the doorlaterally out of its opening and one object of the inven tion is the provision of resilient means 0pcrating upon the unlocking. of the door to force the door outwardly. from its opening to clear the wall of' the car and perm t longitudinalmovenient of the door.

Anotler object is the provision of a rigid hanger having its main members adapted for economical construction from standard rolled sections. 7

Another object is to provide an improved. supportingand looking device, which open ates, to support the door" and also permitsthe door to be moved separably toward or away fromjthecar wall and parallel thereto.

Another object is the provision of p fited mea s; for or t o int closed position and locking the same.

The objects of the invention thus generally stated; together with other and ancillary advantages, are attained by the constru ction andjarrangement illustrated in the.

accompanying drawing forming part here of, but it will be apparent that imriousv changes in the form, construction and arrangement of the parts rnay be made by those skilled, in the art without departing from the spirit and scope of the invention as expressed in the appended claims.

In the drawings, Figure 1 is an elevation of a sliding door mounted ona car and equipped F 1g. 2 is with the device of rnyinvention. an enlarged scale sectional view on the line, 22 of Fig. 1. Fig. 3 is a detail sectional View on the line 3-3 of Fig. 2. Fig. 4 isan enlarged scale detail sectional view on the line ',4? of Fig. 1. Figs. 5 and, 6 are detail. v

views.

The construction which I have selected for purposes of illustrationisdesigned pri marily for use with a freight car, although. it is to be understood that the invention not limited to use on a car or other. vehicle,

were.-

but may be used on buildings such as houses, icehouses andthe like.

. at The construction comprises in general a 1 two-ply sliding door 1- supported at its upper end by a track 10 and adapted to close. I an opening 21 in the sidewall .22. of the.

car. The track 10 comprises a Z'bar rigidly.

web extending horizontally.

The hanger comprises an angle--7and, a channel 8 fastened together as-by rivets 23. and rigidly fastened to. the door 1. The channel 8 substantially encloses the track 10 and provides a mounting for. the rollers 19 which support the door and permit its easy movement longitudinally. Pins20 mvide journal bearings for rollers 19 are vingat its lower end with a cam 17. Their od 6 is 'pivotally supported on the angle7 by th'e cam 18 and mayberotated an arm QQ which is mounted on. the'lrod toward its.

lower end so as to be accessibleffromthe ground. The cam 17, below the angle. 13, acts as a stop against the, upper flange of the Z bar 1 1, to limit the outward movementofthe .door. i

The

cams

17 and 18 are fastened on rod 6 at an angle of ninety degrees with each other (Fig. 5)v and with the arni 2 posi tioned so as to make an angle of one hundred eighty degrees with'thecam 17 (Figal'and A rod 4 fastened to the wall'22 and a pin 3 are provided to fasten andSeaIthe door 1 in the well known manner.

fastened to the sidewall of the earwith' i,ts

outer leg project ng downwardly and In Figs. 1 and2 thedoor is. shown. in.

closed I i a with the cam 1 in C n ct ith the Z bar 10 and the Carr 17 tu parallel to the door.

18 from the Z bar 10 and turns the cam 17 into engagement with the guide bar 16 thereby forcing the lower end of the door outwardly to clear the wall of the car. The upper end of the door is simultaneously forced outwardly by the action of a spring 9 (Figs, 2 and 6) which is mounted on the web of the channel 8 by means of bolts 12 so as to bear constantly against the downwardly projecting leg of the Z bar 10. The spring 9 acts to yieldingly hold the door out wardly away from the Wall 22 and is made sufficiently rigid to move the door and hanger outwardly and keep the cam 18 in contact with the 21 bar 10 as the cam is rotated. The rollers 19 are slid longitudinally on the track by the lateral movement of the door and are of sufficient length that when in their outermost position they have ample bearing on the Z bar 10. The door 1 can then be rolled along the track 10 until it strikes the stop 15.

Thus it will be seen that I have PlOYlLlBLl an improved supporting and locking device of substantial construction for a car door or the like which is manually operable to force the door laterally into closed position and which upon release of the locking device automatically moves the door and hanger outwardly from the car to permit of its longitudinal movement to open position.

I claim as my invention:
