AMOS O. BANKS AND JOHN J. TATUM, OF BALTIMORE, MARYLAND, ASSIGNOR-S TO THE MARYLAND RAILWAY SUPPLY COMPANY, OF'BALTIMORE, MARYLAND, A CORPO RATION OF MARYLAND.

DOOR-HANGER.

No. 896,265. Specification of Application filed July 25,1906. Serial No. 327,743.

-To all whom it may concern: Be it known that we, AMos O; BANKS andi; JOHN J. TATUM, of Balitmore, Maryland, have invented a new and useful Improvement in Door-Hangersflvhich improvement is fully set forth in the following specification.

The object of the present invention is to provide means for hanging the doors of 10' freight ears and other structures'in such way that the doors may be readily moved to one side for the purpose of opening thecar Without undue binding of the supporting hanger upon the track, while at the same time pro viding an anti frictional bearing to the hanger, withmeans for excluding rain, snow,

sleet or other foreign substances which would interfere with ready movement of the parts; and furthermore to provide means whereby the entrance of the elements, and particularly snow and water, into the car over the. door may be prevente d For the purpose of protecting the antifrictional bearings of the door hanger,-and also'for the purpose ofpreventing the eIitrance of snowand rain over the top of the door, a hood'Ihas-heretofore been providedof sheet metal or wood. Not only has this hood been found to add an addition l element of expense, but it has also been found objectionable since the hood is liable to become detached and by projecting outward from the face of the car to engage cars passing on opposite tracks and cause, serious damage. i

The object of the present invention is to provide means whereby rain, snow, slush and ice can be effectively excluded, not only from the interior of the car itself but from the hanger bearings, without the necessity of employing such additional parts, and with this object'in view the invention consists in mountinga track above the door opening which track is provided with means for securing it to the car body, va substantially horizontalway for the door hanger to travel upon, and a downwardly depending. flange. The hanger supports the door with its upper edge between this downwardly depending flange and the wall of the car and above the door opening, thereby preventing the elevments from passing into the car over the top of the door. The roller of the hanger is protected from interference by the elements Letters Patent. Patented Aug. 18, 19 08 which substantially incloses the roller ex- -the horizontal portion of'the track or way.

Another, difflculty experienced incar doors is the inclination of the same to stick and produce a strain upon the parts when the door is seized by .One lower corner for the 'cept at the lower portion where it bears upon purpose of moving it upon the track. For

the purpose of preventing this binding action .it has heretofore been proposed to attach a secondroller to the hanger which shall en and the downwardly-depending flange of the i I track is so arranged in connection with the body of the hangeras to cover and, in comsnow, slush and ice from the roller and its bearings.

The invention-will be better understood by reference to the accompanyingv drawings,

wherein hanger in position on the door of a freight car; Fig. 2 is a vertical sectional view; and Fig. 3 is a vertical sectional view illustrating another expression of the inventive idea.

' Referring tothe drawings, 1 is a suitable hanger-plate adapted to be secured to door 2 by screws 3, and 4 is a hood within which anti-frictional roller 5, which normally engages the guide rail, is mounted. Preferably said hood is cast integrally with the hanger-plate 1, the spindle 6 on which antifrictional roller 5 is mountedpassing through the front and back walls thereof; but, if desired, said hood may be'separately formed and secured to the hanger plate in an 7 desired manner. And, indeed, the roller 5 instead of having its hearings in the walls projection 7, as shown in Fig 3. Preferably the hanger plate has also cast integrally Figure 1 is a perspective View showing the bination with the boxing, practically exclude of said hood maybe suitably mounted on a therewith a boxing or housing 8 which completely surrounds an anti-frictional roller 9 and in the .walls of which boxing roller 9 has bearings, as shown in the drawings. The

height of this boxing is substantially that of.

the diameter of the said roller 9, which latter,

by means of a suitable hood or covering as is well known, is adapted to engage the lower face of the horizontal portion of the Z-shaped rail or track to prevent the door from jamming when the same is moved, as it would if said anti-frictional roller 9 were not present.

' 8 are so cast as to provide a assage-way 11 between them, within whic extends the lower vertical flange 12 of the Z-shaped rail, which latter is suitably secured to the car 10 or'other structure 13 by screws 14 passing through flange 15.

As shown, housing 8 is preferably set in a cut-out portion 16 of the door, the upper edge 17 of the door being approximately coincident with the upper edge of the housing 8, so that the'bottom edge 18 of flange 12 is in a horizontal plane lower than that of the up er edge 17 of the door.

t will be observed that, even should rain drive onto the Z-rail under hood 4, it would simply flow therefrom down into the pas sage-way 11 and from thence out through opening 20 formed in the hanger plate 1.

In Fig. 3, which is another expression of the inventive idea, the hood 4 for the up er anti-frictional roller '5 extends -slightly rther inward toward the car or other structure than is shown in the other views, and has a' straight horizontal edge 18 engaging the top edge 19 of flange 15. .Further, the antifrictional roller 5, instead of having its bear over the top of the door is effectively pre vented.

What is claimed is:

1. The combination witha car and a door therefor, of a track secured to the car above the door 0 ening and havin a flange extending down slow the top of t e door, a hanger plate secured to the door and having a hood at its upper end, a boxing open at the top and interme tatively mounted in said hood and having a The hanger plate 1 and boxing ing witnesses;

iate the ends of said plate, a part robearing surface to bear on the top of said track, and a part mounted in said box to project from its open end and presenting a bearingsurface adapted to engage the under side of said track.

2. The combination with a'car and a door above the door opening and having a flange extendi v hanger p ate secured to the door and having ahood at its upper end and a boxing open at the top intermediate its-ends, a supporting roller mounted in said hood to bear on the,

to ofsaid track, and a roller mounted in said boxing to permitits periphery to project from its openend whereby it is adapted to engage the under side of said track.

therefor, of a Z-track secured to the car 7 down below the top of the door, a t

3. Thecom-bination-with a car and a door' therefor, of an outwardly-projecting substantially horizontal track .secured'to the carv above the door openingand provided with a flange extending down below the top of the door, a hanger plate secured to the door and having ahooclht its upper end, a boxing open at the top and intermediate the ends of said plate, antifrictional bearings mounted on said hanger to bear on the top of said track, and antifr'ictional bearings'mounted in said boxin to project from its open end whereby it is a apted to engage the under side of said track.

4. The combination with a car and a door therefor, of a track secured to the car above the door openin and having a flange ex tending down be ow the top of the door, a hanger plate secured to the door and having a hood at its upper end, a boxin secured to said hanger plate and supports under the the lower downwardly-extending flange on the track and with its top substantiallylevel with the top of the door, a roller mounted in said hood and bearinghpn the top of the track,

and a roller having arings" in said boxing and projectin slightly above the same so as to engage the ower face of said track.
