CAR-DOOR SUPPORT.

Application filed December 15, 192%. Serial No. 755,824.

This inventionrelates to a car door support; l

Under existing practice, car doors are supported upon a pair of spaced rollers either at the bottom or at the top. It has been found in practice that no matter how perfectly a car door would be hung on a car, a short trip would cause a settling or distortion of parts so that it became very difficult to operate the door. 7

It is an object of this invention to overcome this objection in the provision of a single roller support for a car door that may support the door either at the top or bottom, in balanced position, that allows a limited pivotal or tilting movement of the door in its plane to assist in the operation thereof and to free it of any bindingrthat might occur. I i

It is. a further object of this invention to provide a novel form of hanger that can be manufactured by the drop forging process and assembled without the use of bolts or rivets and that will support the door without putting the attaching bolts in shear.

WVith these and other objects in View which will become more apparent in the following description and disclosures, this invention comprises the novel structure and combinations hereinafter described and more particularly pointed out and defined in the appended claims.

'In the accompanying drawings which illustrate a preferred embodiment of this invention and in which similar reference 'nunierals refer to similar features in the different views:

Figure l is a fragmentary broken elevational view of a car door showing this invention applied thereto.

'FigureQ is an enlarged view taken upon the line II-II of Figure 1, with parts removed.

Figure 3 is a plan view of the anti-friction rollers on the door.

Figure 4 is av plan View of a modification of anti-friction roller construction for the door. 7

Figure 5 is an enlarged elevational view of the main door hanger.

vFigure 6 is an enlarged side elevational view of the main door hanger.

Figure 7 is an enlarged plan View of the hanger in disassembled form illustrating the assembling thereof.

As shown on the drawings:

In referring to the drawings which illusextends the vertical roller supporting arm 4:.

The outer'surface of the hanger is provided with a plurality of strengthening ribs 5. The upper end of the roller arm terminates in a transverse plate 6 having inwardly projecting spaced bosses 7 to provide a spacetherebetween for the reception of a roller 8. These bosses terminate in reduced rivet shanks 9. The plate 6 is. provided withia polygonal socket 10 for receiving the poly onal end 11 ofthe roller supporting axle. A plate 12, likewise provided with a poly onal socket 13 adapted for fitting over the opposite end 11 of the roller supporting axle, is provided. This plate has a pair of spaced apertures 1% for receiving the rivet shanks 9.

In assembling this hanger the roller 8 is positioned upon its axle and then placed between the bosses 7 with the polygonal end 11 of the axle engaging the socket 10. The plate 12 is then positioned so that the socket 13 will engage over the polygonal end'll of the roller axle and the apertures 14 will ei'igage over the rivet shanks 9. The rivet shanks 9 are then swaged over the plate 12 for combining theplate with the casing.

This hanger is adapted to be centrally supported at the top of a car door 15 for suspending the same in balanced position, the shoulder 3 engaging under the web of the Z bar 17 for taking the shear oft the attaching bolts of the hanger. The roller 8 travels upon the usual track 16. As the upper edge of the door is spaced below the track, the door can pivot upon the roller 8 or in other words can be tilted in its plane until it strikes the track. In operating the door, the upper surface adjacent one end'thereof is usually elevated into engagement with the lower surface of the track and a good deal of friction wouldbe engendered. To overcome this friction. anti-friction elements are interposed between the upper ends of the door and the track. In referring to Figure 2 it will be noted thatthe upper border of the door consistsof the 2 bar 17 and adjacent each end of the web of the 2 bar there is secured a casting 18 having an upstanding arcuatelug 19 to reducefriction and opposed to the up- Jstanding flange of the Z bar17. A short casting'IS issimilar to the casting 18 except that it I contains a vertical support for an anti-friction roll 22 which is adapted for rolling along the inner surface of the depending flange 16 of the track 16 for guiding the door, in itsmovement, theupstanding flange of the Z'bar'17ibeingcut away to allow the roller to project therethrough. The casting 18Tin connection with the Z bar supports the anti-friction roll 21'as in the case of the 7 structure shownin Figure 3.

From theforegoing it will be apparent thata novel form of door support has been provided which is assembled without the use of bolts or rivets and which is located so as to balance the door ;howeveryallowing the same 2 to be slightlyftiltcd to overcome anybinding and? forswingingthecenter of gravity s st ng the operation thereof."

jlVe are aware that many changes'may be for asmade; and numerous details of construction may be Varied through a Wide range without departing from the principles of this invention, and we therefore do not purpose limit 7 ing the patent granted here-on, otherwise than necessitated by the prior art.
