V l. SHAFER SLIDING DOOR SUPPORTING v APPARATUS Fiied July 6, i942" J m 5 H. 7/ 7M |.l|fl J .H mw v v v a m 4 2: 2 d 4 a2 y M w F 16 M a; 7/////%// m w ATTORNEY Patented, Oct. 9, 1945 ;eo aim' 01120519115 Myinvention relates to a sliding door supporting apparatus particularly arranged for use in suspending doors in shiftable edgewise relation "withthedoor opening. and shiftable into, narrow walls, and the objects of, myinvention are;

First, toprovide a sliding door supporting apparatus of this, class in which the door-rides i freelyv on, a carriage mounted on a track, over head.an d extendinginto the wall and in which the ,carriage will notjam or become wedgedin the door supp g i m i i Second, to prov del a door supporting apparatus ,of this class in which the door. may be rea dily'and quickly'po'sitionedor removed through the ordinary door opening from either sideof the Wall;

j Third, toprovide a sliding door supporting apparatus of this'class in which the height ofthe door relativeto its: supportin track may be readily adjusted; 1

' Fourth, to provide a sliding door supportin g ap paratus' of 'thisclass in'vwh ich the door may beinstalled by positioning one of the carriagesfirsti'n the door opening near one side; whilefthe" other portion of the door remains in the room, 'then'b'y shifting the other side of the door into position andfmounting the same on'thetrack; l f

Fifth, to provide a sliding door supportingapparatus of this class in which the door and the 7 supporting apparatus may be readily installed or "removed and adjusted to" varying heights;

Y E

-With' these and other objects'in'view as will appear hereinafter, my invention consists-of certain novel features of construction, combination and arrangement'of parts and portions as Will'be hereinafter described in detail and particularly set forth in the appended claimareferencebeing. had to the accompanying drawing and to-the characters of reference thereon whichform a part-of this application in which: L Figure 1 is a' transverse sectional viewof-the door supporting track, carriage and door shown 'fragmentarily taken from the line l-l' of Fig. 2;

" Similar characters'of reference refer tosimila throughout the several views The track members i and door-r3, carriage guides 4; carriage axle 5; carriage wheels fi grease retainers "1',door'supporting bolts 8 and; 9, door supporting plate 18 and door supporting; latch to i constitute the principal parts and portion of my sliding door supporting apparatus. ,f.

.The track-members'1 :and, 2 arepreferably L- shap'edsmembers, preferably made of wood and supported in spaced relation to each other, as

shown best in-Figs; 1 and 3 of the drawingand extend over theppening forthe door and-into :the wallat the sideofthe door and form a trackway for supporting the door when itis shifted-into the'wall' from the openin as Well as when the door closes the; opening'; These tracks may be supported 'in any manner desired and;may be provided with specialtrack portions l:a audio to provide a specialwearing surface for'the wheels'6. 1 Mounted on these tracks la and 2a or uponthe inwardly extending portions ofthe members I and. 2 is a pair .of carriages each consisting] of wheels '6, which are revolubly mounted upon .axles Eat their'opposite ends. Thesewheels 6 are provided on theirinnersides with grease retaining vmembens, 1 which are-filled with relatively hard grease to provide lubrication for the carriage wheels onthe axles. v a

",Mounted on each of the axles 5 is a substantially U-shaped guide member}! ,which extends downwardly betweenrthe inwardlyextending portions of the track members I and 2, a shown best inFigs. 1 and 3'of.the,drawing. {These members 4-serveas guides-for guiding. the wheels 6 in their proper relationpnltheltrack members I and 2 so that they .donot bind or wedge in the open space jbetweenthe track members jfl. m

Screw-threaded in one of the carriage 4 at its lower side and e xtendingb etween the upwardly extendingmembers thereof is a bolt 8 whichlis providedwith a square shank portion 8a in its head; which is positioned; in aconforming shaped-opening 8b and itis provided with a flat .-head portion v 8c.1which fits against the top of the door and this bolt is secured'inposition by means lof-a plat c 811 which iss'eol red on. the upper edge of the door near one side by means of screws or the like.

Mounted in the carriage guide I on the other carriage is another bolt 9 which is screw threaded therein in the same way as the bolt 8, but this bolt 9 supports the door in a different manner. The door at this other side is provided with a rectangular shaped recess 3a, as shown best in Figs. 3 and 4 of the drawing, and over this recess is mounted-a 'plate III by 'of screws Illa. This plateis provided with an opening Illb therein and is provided with an enlarged portion Ic which is adapted to receive the'head 9a of;

the bolt 9 and when the carriage together with side of the door, the square portion 9b of thebolt 9 will extend into the narrow portion of the slot Illb which prevents the turning of the bolt 9. This plate I0 is also provided with an upwardly extending pin IIld which extends upwardly a slight distance from the uppersurface of the plate II); It is also provided with a slot IIle in its end.

Positioned on the bolt 9 above the square portion db .is a latch II which is an elongated plate provided'with elongated slots I Ia and Iilb near its opposite ends and is adapted to fit over the bolt 9 above the square portion 9b at its one end :and

' over the pin Iilld at its opposite end when the door is installed in its operative position, shown in Figs. 3 and 4 of the drawing:

The ends of the inner extending portions of the track members I and 2 are cutaway at b and 2b a suificient distance to permit the wheels of the carriage Ii to be raised upwardly through the opening provided by the cutaway portions 1 b and 2b, as shown best inFig. 5 ofthedrawing;

The operation and installation of my sliding door supporting apparatus is substantially as follows:

One of the carriage members "is pivotally connected with the door at the one end in :its adjusted relation, and positioned with the wheels traversing the door at one side of its upper edge and'the lower side of the door is positioned slightly on an angle so that the carriage may be inserted through the openingsformed by the cutaway portions Ib and 2b in Fig. 5 of the drawing, then the door is straightened up and the carriage enters the opening until the wheels are above the track portion, then the carriage, together "with that particular side of the door is shifted longitudinally on the trackway,=as shown in Fig.5 of the drawing. Then the carriage with the bolt 9 and latch I I is inserted through the opening formed by the cutaway portions lb and 2b and the wheels shifted longitudinally onto the trackways ofthe members I and 2 the latch member extending .backwardly. Then the door is shifted into alignment with the 'trackway and the free side of the door is shifted upwardly so that the'bo'l't head 9a passes through the opening Inc, then by shifting the latch member I I endwise, the square portion 9b of the bolt enters the narrow portion I'Uc of the slot so that the door is supportedby the bolt head. The latch is then shifted to a position where the pin IO'd enters the .slotflila of the latch member II and the door is ready for continuous operation.

To remove the door, a. pencil or sharp pointed instrument is inserted through the slot IIle under the latch II and the latch raised until the point 10d is xdisengaged from the slot I I a. The

latch is then drawn :backwardly or the door moved away from the same until the bolt head reaches the opening H10 in the member In and the door can drop below the bolt head and the door can then be shifted to the position shown in Fig. 5 of the drawing. Then the other carriage may be shifted backwardly and removed through the opening formed by the cutaway portions Ib and 21).

It will be noted that with this structure and mode of operation no stops are required at the opposite sides of the door at the top side and the door may be adjusted 'at the one end by simply dropping the door at the one end and screwing the bolt 9 into the guide member 4.

Though I have shown and described a particular constructiom combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.
