Claims.

This invention relates to hangers for doors and concerns itself more particularly with hangers for use with sliding car doors of the flush type. -'It is among the objects of this invention to 5 provide a hanger for sliding car doors which shall door, each of said rods having an operating lever adjustably secured theretoto insure proper seating of said door in its door opening.

Another object of the invention is the provision of a door hanger comprising a plurality of vertical bars rotatably secured to said door, each of said bars carrying'an operating lever, and means mounted on said door for automatic engagement with said levers when the latter are operated to remove the doors from their openings to effect smooth unimpeded sliding movement of the doors.

''Other objects will appear as the description of this invention proceeds.

In the drawings forming a part of this specification:

Figure 1' is a fragmentary elevation of a house car illustrating a door supported upon a hanger embodying this invention.

Figure 2 is a vertical sectional view taken on line 2-2 of Figure 1, the door being shown removed from its opening in dot and dash lines.

Figure 3 is a horizontal section taken on line 3--3 of Figure 1.

Figure 4 is a view. similar to Figure 3 showing the door removed from its opening and in position for sliding movement.

Figure 5 is a detail in elevation of a combined bearing and latch member.

Figure 6 is a top plan view of Figure 5.

Figure? is a detail of a hook utilized in the combined bearing and latch member.

Figure 8 is an enlarged partial elevation looking in the direction of the arrows 8--8 shown in Figure 4 of the drawings.

Referring to the drawings in which a preferred embodiment of this invention is illustrated thenumeral 10 indicates generally a house car. There is provided in the car 10 a door opening defined by the vertical doorposts 11 and 12 and by a lintel 13 and threshold 14. As clearly shown in Figures 2, 3 and 4, the car illustrated is pref erably a refrigerator car.

A door 15 may be used to close the opening in the car. This door comprises essentially a metallic construction. It embodies an outer metallic plate 16 formed preferably of a plurality of dished panels 17 and 18. These panels provide horizons. tal corrugations 19 and 20 and vertical corrugations 21 and 22. The door construction fur ther embodies an inner metallic plate 23 spaced from the outer plate 16. An angular reinforcing frame 24, substantially Z shaped in-section; :is employed to connect the inner'and outer'plates' in order'to constitute the main door structure; The inner and outer plates are preferably riveted to the flanges of the framing member 24 as clearly indicated in Figures 2, 3 and {of the drawings. The framing member 24 is preferably rounded at its corners and the innerand outer metallic plates follow the contour ofthe framing. member. By this construction asubstantially rigid door is produced. vIt is understood, of course, that the door openingis correspondingly rounded at its corners. It follows from this construction that all possibility of. pinching-of the door in the door opening due to the weavingand racking of the car is avoided. The great strength imparted at the corners of the door by this'construction also avoids opening up of the joints at such corners. The framing member 24 is provided with a plurality of ofiset tongues 25 and 26 formed around the perimeter of said frame and extending outwardly therefrom. These tongues cooperate with a flange on the Z-bar frame and with a plate member 27 to pro.- vide grooves in which continuous sealing members 28 may be received. Thesesealing members in their operative position preferably contact with wear plates providedvin the-post, lintel and threshold members. 1 e g Positioned within the door is a wooden frame 30 conforming substantially to the contour of the reinforcing frame 24s The door 15 is insulated by means of a plurality of layers of com pressed insulating material 31 between adjacent layers of which a plurality of layers of loose insulating material 32 is positioned. 'These layers of insulating material are maintained in position against the inner plate 23 by means of Wooden spacers 33 which may be secured in position by any suitable means to the wood framing member 30. These wooden spacers also maintain the insulating layer 31 against the outer plate The construction of the door has: been de-v scribed in some detail but no claim is made herein to this construction. The door structure will form the subject matter of another application. The door is supported for lateral movement relative to the door opening and for sliding movement toward open and closed position by means of a hanger comprising a plurality of vertical bars 40} These bars are rotatably retained on the door by means of a plurality of bearings '41 and 42. The extremities of the bars 40 areprovided with offset portions 43 known as goose necks. Secured to each of the vertical bars 40 is an operating lever 44 pivoted eccentrically as indicated at 45 between the spaced flanges 45"---45 provided on a collar 45 adapted to be flxed upon a bar. The outermost of said flanges is of greater height than the innermost flange for a purpose hereinafter set forth. A set screw 47 is utilized to retain the portion 45 in the desired relationship upon the bar. By means of this construction it is evident that the wear of the weather or sealing strips 28 may be compensated for by varying the initial angular relationship of the levers 44- with respect to the bars 40. This variation is permitted by means of the set screws 47. It is observed that the levers 44 move toward each other when the door is being seated in its opening and that in the latter position these levers overlap. The overlapping portions are provided with aligned openings 48, through which a staple 49, carried by the door, is adapted to extend. A latch 50 may be utilized to retain the levers. intheir overlapped position as well as to provide means for sealing the door.

The goose necks of the bars 40 are journaled in upper carriages 51, these carriages being. supported and guided during the sliding movement of the door by'means of a retaining member 52 mounted upon the car above the door opening. The lowerextremities of the bars 40 are journaled in carriages 53 which are adapted to have sliding. movement upon a track 54 by means of rollers 55 provided in said carriages and having engagement with said track.

The bearings42 utilized to rotatably maintain the bars 40 in position upon the door constitute preferably an integral portion of a bracket member 56 adapted to be secured to the door. This bracket member is provided, additionally, with a forwardly projecting flange 57 from which extend a plurality of spaced ears 58. Between these ears a hook member 59 is pivoted by means of a pin- 60 extending through aligned openings in said ears. is provided with an engaging nose portion 61 while the opposite end thereof is formed with a lug 62 adapted for engagement with the flange 57 provided on the bracket in order to limit the upward movement of the hook member.

The door is limited in its sliding movement by aplurality of stops or brackets 63.

When it is desired to move the door from its closed position within the door opening toward its open position, the latch 50 is disengaged from the staple 49 and the levers 4444 are swung outwardly. During this movement of the levers the bars 4040 will be rotated and because of the goose neck formations thereon the door will be moved bodily out of its opening. During this movement of the door the outer flange 45 will engage the nose on each of the hook members 59 automatically elevating said member until engagement between the nose portion and said outer flange 45 has occurred, This engagement,

One end of the hook member 59 because of the connection between the levers 44-44 and the operating bars 4040, will maintain said bars and consequently the carriages in which they are journaled in fixed position during the sliding movement of the door. The carriages, consequently, have a steady unimpeded movement along the retaining bar 52 and the track 54. Without this rigid positioning of the bars 40-40 during the sliding movement of the door it has been found that this movement has been jerky and undesirable. In addition to providing a steady, regularmovement of the door the hanger mechanism described insures such movement at all times in View of the fool-proof and automatic construction provided.

t will be observed that the nose of each hook member 59, when said portion is in engagement with the outer flange 45 will lie in the space between said outer and inner flanges 45 It is also apparent that when the door has been moved out of its opening the levers will gravitate to vertical position. When it is desired to force the door into its opening each of the levers is grasped and moved to horizontal position. During this movement and because of the eccentric pivotal connection of the levers engagement between the levers 44 and the nose 61 of the hook members '59 will occur and bring about automatic disengagement: o'f said hook members with the outer flange 45 provided on the collars 45. It is noted, furthermore, that the levers are utilized merely for swinging the door into and out of its opening but are not employed during the sliding movement of the door. It is manifest, therefore, that not only is the engagement between the members 59 and the levers, 44 automatic, but that the disengagement of these parts occurs automatically as well.

It is apparent that numerous changes and modification in the details of this invention may be made. It is to be understood that all such changes and modifications are comprehended within the perview of this invention, which is to be limited only by the scope of the claims appended hereto.
