Either method of hanging the door may be employed, the choice being ordinarily left to 1 the body manufacturer; .although either method is equally satisfactory. For this reason both. methods' have been illustratedand described; Thus, Figure liandFigure .5 disclose the method of suspending the 'doorfrom hangers along its top' edge and:

I v i A's-clearly shown in Figure'b, the lower edgeof'the door extends a short distance below the floor 7 and to the bottom edge otsaid do'or are attached a pair oif fr'etain ing rollers l5,-v there being; preferably two otf these-retain'ing rollers used in" anordinary' Y installation and preferably" arranged as shown in Figure 1. Figure shows the complete assenclbly of one otijthese retaining" -1-o11ers';- which comprises a strip 15*, of re si'l'ient metal such as spring steel, having mounted at one enda journal block 1 5 at one end of which a grooved'disk or'roller 151" is j'ournalled. As-clearly shown in Figure 1, th'e'strips are fastened end'to end near the c'en-ter of the door-frame and extend lengthwise thereof in opposite directions so" thatythe rollers 15 are disposed just in wardly fr'omeac'h end-of the door. More' overyasclearly shown in Figure=5,the rollers 15 are ofiset inwardly from the door and clear the lower edge thereof by a distance of a quarter of an inch or so;

Fastened along the edge ofthefloor 7 is a'longit'udinal plate or strip 16' having itstop and bottom edges-extending a short distance above and below the floor 7. The lower edge of the plate 16 forms" a down wardly facing track along which ride the retaining rollers 15; Along the lower" edge of the-,door-I"ran1e is preferably; attached a plate 17 with its lower portion projecting downwardly below the retaining rollersand thusservingto conceal them from view-and to; protectitheml from llljuly';

although in general construction and design they are essentially the same. Thus a bottomdoor hanger isconstructed of sheet metal shaped to form; a main Vertical web 19% l1aV1ng1ts upper portion bent at right angles and thence downwardly to form a parallel web l9 terminating substantially midway between the upper and lower edges I of themain vertical web- 19 andforming therewith the downwardly'opening U-sh'aped,

Along the lower edge of themai'n web 19 is a short transverse flange l9 -forined by" bending the lower" edge portion of said web at ught anglesfin the same dlrection asthe upper portion is bent to fornithe inverted U -shaped roller support.

As clearly shown in Figure 6, each bottom hanger 19 is screwed or otherwise fastened to the inner face of the door and 'nearits lower edge-and: in such a way that the lower' flange 19"projects inwardlyjust below thelower edge ofthe door and} in suchposition Just clears'the under sidefof the fioortrack' roller} engaging'the top edge: thereof. a
