DOOR HANGER AND TRACK.

Specification of Letters Patent.

Patented July 9, 1912.

Application filed. August 29, 1911. Serial No. 646,600.

T 0 all whom 2'25 may concern Be it known that I, DWIGHT A. Donen, a citizen of the United States, residing at Haywards, in the county of Alameda, State of California, have invented certain new and useful Improvements in Door Hangers and Tracks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in door hangers, and is especially adapted for use in connection with freight car doors.

The principal object of the invention is to provide a track formed from gas pipe and secured to the car or support in such a manner that any tendency of displacement of the same due to the weight of the door, is prevented.

Another object of the invention is to provide a hanger of the character described, which is simple in construction, and is therefore cheap to manufacture.

With these and other objects in View, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claim, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing: Figure 1 is a detail front elevation of a freight car. showing my invention associated therewith. Fig. 2 is a detail transverse sectional view through the same, and Fig. 8 is a perspective view of one of the track supports.

Like reference numerals designate corresponding parts in all the figures of the drawing.

Referring to the drawing, the invention comprises a freight car or other support which includes a side 5, a longitudinal upper beam 6, a door opening 7 and a door 8. Disposed above the door opening is a track 9. This track is formed of ordinary gas pipe. and is cut longitudinally to form a longitudinal opening 10. The lower edge 11 of the pipe is bent upwardlv to form a longitudinal flange. Formed in the pipe opposite the opening 10 is a plurality of spaced openings 12.

Formed in the side 5 of the car directly above the door opening. 7 is a plurality of spaced recesses 18, each of the recesses being adapted to receive a support for the track 9. Each of these supports is formed from a strip of sheet metal, and has one end 15 bent and seated within the recess 13. The strip thence extends outwardly below the track 9, as indicated by the reference numeral 16, and the free end. 17 thereof is rebent and convexed to conform to the exterior shape of the track 9. Formed in the ends 15 and 17 of each support are openings 15 and 17 respectively, which register with the openings 12 formed in the track 9. Bolts 18 are passed through suitable openings formed in the beam 6 and the alined openings 15, 17 and 12 of the support and track, and the head 19 of said bolt is disposed within the track proper. The undersurface of the head 19 is conveXed to conform to the interior face of the track 9. A nut 20 is associated with the opposite end of the bolt, and by this means the head 19 can be tightly drawn against the ends 15 and 17 of the support. Disposed bet-ween the free ends of the support is a wedgeshaped key 21, which is adapted to hold the end 17 of the support in its proper shape.

Secured to the door 8 are U-shaped hangers 22 having bearings 2323 formed at the ends thereof. Disposed within these bearings are suitable shafts 24. and rotatably mounted on each of the shafts is a wheel 25. These shafts project within the opening 10 of the track and into said track, and the wheels 25 engage within the lower portion of the track and are prevented from outward movement therefrom by means of the longitudinal flange 11.

The upper outer edge of the door 8 behind the hangers 22 is recessed, as indicated by the reference numeral 26. and seated within said recess is a longitudinally extending weather guard 27. This guard is pref erably formed of sheet metal and the upper edge 28 thereof projects beyond the top of the door 8. It will thus be observed that this guard plate projects across the opening between the door and the track therefor when the door is in its closed position, and prevents any possibility of rain, snow or other foreign elements passing through said space and entering the car.

WVhatis claimed is In combination with a car having a door opening and a plurallty of recesses formed in the car above the opening, of a plurality of supports, each support being formed from a strip of sheet metal and having one end bent and disposed within one of said recesses, the strip thence extending outwardly and having its free end rebent and conVeXed, the ends of the strip being formed with alined openings, a track formed from gas pipe and disposed against the conveXed end of the strip, said pipe being split longitudinally and the edges spread apart to form a longitudinal opening, the lower edge being bent upwardly to form a flange, the pipe being formed with a plurality of apertures disposed diametrically opposite the longitudinal opening and in registration with the alined openings of the supports, bolts disposed within the alined openings of the track and the supports and secured to the car, a door, hangers secured to the door, a shaft journaled in the hangers and projecting through the longitudinal opening into the pipe, and wheels carried by the shafts and disposed within the pipe beyond the flange.

In testimony whereof, I afiix my signature, in presence of two witnesses.
