To all whom it may concern:

Be it known that I CORNELIUS J. Bani/IAN, a citizen of'the Unlted States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Door Structures, of which the following is a specification, reference being had to the accompanying drawthis general character whereby the door proper may be supported or suspended in a manner to facilitate the requisite sliding movement and whereby the door, when in open position, may be arranged at an angle to the wall containing the doorway to ther by economize space while at the same time leaving the doorway entirely free and un obstructed.

Another object'of the invention is to pro vide a door structure embodying two doors supported for sliding movement, one relative to the other, in association with doorway, together with means for suspending or supporting the doors in a manner whereby said doors may come into close contact one with the other when in closed position.

The invention consists in the details of construction and in the combination and arrangenient' of the several parts of m y improved door structure. whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel feature of niy invention will hereinafter be definitely claimed.

ln orderithat in invention may be the better understood, will now proceed to describe the same with reference to the accompanying drawings, wherein:

As disclosed in the accompanying drawings, 1 denotes the front wall of a garage or other building structure provided with relatively wide doorway 2, two or more side walls 3 and a ceiling l. Extending along the sidewall 3 are the overhead straight tracks 5' supported in applied position through theinstrumentality of the brackets 7 to be hereinafter more particularly referred to,

Parallel with the tracks 5 are thetraclrs 8 supported, as will hereinafter be explained, by the brackets 8. Eachof the tracks 8 is continued by an arcuate traclr t) preferably a having a relatively long radius The tree 9 is supported by a bracket 10 to he more particularly referred to and the track 9 is continued by a tracl: 11 extending along the doorway 2 at a point thereabove. This track 11 is common to both oft-he arcuate tracks 9 and is supported by the braclrets l.

The tracks 5, 8, 9 and 11 are all substantially of the same cross sectional configure tion and each consists of'an inverted trough or ll-shaped member having its lower man ginal portion defined by an inwardly arranged fiange 12, the intermediate portions of which provide bearing surfaces ll. Each of the flanges 12 at opposite sides of its bear ing surface it is beveled inwardly and upwardly, as at 115, in order to assure the hang ers, to be hereinafter more particularly re-' ferred to, properly traveling upon the e aring surfaces 14 of the various tracks.

n the present embodimentof my invention, I employ two doorsD each comprising a plurality of hingedly connected sections 16, preferably three in number. withthe upper rear .corners of each of the two outer sections 16 of a door D are-the hangers H and a third hanger H also coacts .with an extension or arm 17 at the u per rear corner of the inner section 16 o the door: Thi last hanger H cooperates 'with tion of the stem are the cone washers 21 between which are interposed the ball bearingls 22. ,Overlying'the out-er washer 21 is a olding washer 23 which. surrounds the reduced shoulder 24 surrounding the re uced portion 20' and whereb the crosshead 18 and the stem 20 are held against relative movement inone direction lengthwise of the stem.

Carried by the stem 20 inwardly of the cross head 18 is a nut 25and interposed between said nut 25 and the cross head 18 is asleeve or bushin 26 surrounding the stem 20. This sleeve or bushing 26 serves to limit relative movement of the stem 20 in one direction and thecross head 18 in the opposite direction.

The upper rear corner portion of each of the door sections 16 and of the extension or arm 17 is provided with a socket 27, the

upper portion 27 of which is enlarged'and.

an lar in cross section. Fittin within the en arged portion 27' is a metal ic block'28 through which is threaded the stem 20, said a d e Bolted or otherwise secured to. the side stem 20 extending within the socket 27.

faces of each of the rear upper corners of the two outer door sections 16 and the extension or arm 17 are the cleats 29 provided at their upper portions with the mwardly dlrected flanges or wings 30 which overlap and are provided with re 'stering slots 31 throu h which an anchoring screw 32 or the 11 is disposed, said screw being engaged with the adjacent portion of the door sect1onj16 or the extension or arm 17. The flanges or wings 30 are also provided with the registering slots 33.through which the stem 20 is disposed, said flanges or wings oacting.

with the tracks 8,'

19 through I about which the cross head 3 18 is ada ted to swing or rock. The stem ortion 20' of the stem 20 and which re uced portion is' 11 set, as at 20" to hold the outer washer 1 a inst the Coacting with the upper serving to hold the metallic block 28 in applied position. Threaded upon the stem 20 and coacting with the outermost flange or wi 30 is a lockin nut or burr 34.

The opposite en portions of the cross head 18 are provided therethrough with transversely directed openings 35 and disposed through each of said 0 enings 35 and extending beyond 0 posite si es ,of the cross head 18 1s a spind e 3.6., The central por- '75 tion' of the spindle 36 is provided therearound with an annular peripheral groove 37 adapted to register with an annular groove 38 produced in the wall of the coacting opening 35. Coacting with said re 3 0 istering grooves 37 and 38 1s an expansib e ring 39 whereby the s indle 36 is locked to the cross head 18 an particularly against endwise movement.

Rotatabl supported by the extended end ortions 0 each of the spindles 36 is a roller including a hub 40 surrounding the ex tended portion of the spindle. Associated. with the extended end portion of the spindle and the hub are the roller bearings 41. The roller R is held to the s indle'36 by the washer or ca 42 throug which the spindle extends, t e outer end portion of t e spindle being upset, as at 36, to hold the washer or cap 42 against displacement. Each outer end portion of the spindle 36, with which the washer or cap 42 coacts is reduced in diameter,-resulting in an annular shoulder 43. Between each of the shoulders.

43 and the adjacent washer or cap 42 are the ball bearin 44.

The rollers fi embodied in the hanger H carried by the extension or arm 17 coacts with the fiat bearin surfaces 14 of the track 5 while the rollers ers H coact with the similar bearing surfaces of the tracks 8, 9 and 11.

, front corner of each of the outer sections 16 of a door I) is a hanger H substantially of the same construction as each of the hangers H hereinbefore referred to except that the crosshead 18 has its outer end portion reduced, as at 45, in width, so that when the doors D are moved into closed position, the adjacent 115. s of the door wi l substantially contact an the corres onding end ortions of the cross heads 18 will interloc g Each of the hangers H is provided with three rollers R, two ofsaid rollers being arranged at opposite sides of the rear or inner portion of the cross head 18' and the third roller being arranged to one side of the cross head 18 at its outerend. The roller R of one of the cross heads 18 is to one side of said cross head'and the single roller carried by the second cro head 18 is at the side thereof remote from the first named single roller. By this means the single rollers, when the doors D are in closed 139 of the remaining hang- 105 v position, ardk arranged substantially directly above h of the doors. This arrangement is of particular advantage as the hangers H offer no hindrance or obstruction to the desired closing of the doors.- J

The bracket 7, hereinbefore referred to is adapted to be secured to a side wall 3 and comprises an elongated strip 46 provided-atits lower end portion with'an outwardly disposed foot 47 which snugly receives a portion of a flange 12 of a track.5. Associated with the-strip 46 is a second strip 48 overlying the upper portion of the strip 46 and to said overlying portions is." disposed a screw 49 or kindred headed shank for holding the bracket 7 in applied-position.

The lower portion of the strip 48 is continued by an outstanding extension 50 which has close contact with the upper portion of the coacting trackway and said extension 50 is continued'by a downwardly disposed er:- tension 51 having close contact with the adjacent side oi the coacting track and terminating in an inwardly directed foot 52 which snugly receives a portion of an adjacent flange l2. v v

lhe bracket 10 is of a type adapted to be secured to the ceiling 4 and comprises a member 54 substantially. in the form of an inverted U and which has its extremities provided withthe inwardly directed feet 55 which snugly receive the adjacent portions of the flanges 12. Secured to the central part of the intermediate portion 56 of the member 54 i a loop strap 57., the extremities of which are anchored to the ceiling 4 by the screws 58 or the like.

I Each of the brackets 5 comprises an elongated strip 59 adapted to be secured at its upper portion to a side wall 3 or the like by the screws 60 or kindred headed members. The lower portion oi the strip 59 is provided with an outwardly disposed foot 61-. The foot 61 has its outer portion 63 upwardly offset.- vlhi oilset portion 63 receives a member 64 substantially in the form of an inverted U and which straddles from above a'portion of an adjacent track 8.

The lower end portions of the side arms of the member 64 are provided with the ops positely directed feet 65 which snugly receive portions of the adjacent-flanges '12 of the track 8.

llnterposed between the upper portion of the strip 59 and the oiiset portion 63 of the foot 61 is a brace or reinforcing strap 67. the upper end of said strap being anchored by the upper screw'or headed member 60 while the lower or opposite end portion of said strap 67 is anchored to the ofiset portion 63' by the holding bolt 6.8; or the like and which bolt also coacts with the member 64 and the traclr 8. 1

In the embodiment of the hanger as is e meeting or abutting edges particularly illustrated in Figure the roller bearings 44 are not employed. It is also to benoted that the curved track 9 comprises two sections riveted or otherwise secured to the coactingbrackets, the construction of the said track 9 being particularly shown in Figures 1 and 8.

Figure 10 as disclosed in the embodiment of my invention is particularly designed for comprises an wise with respect to thedoor l) as the occasions oi? practice may require. Pivotally engaged as at '40, 1s a bracing strip 7] which is adapted to be anchored to the adj a cent vertical edge of the door D.

From the foregoing description. it is thought to be obvious that a door structure constructed. in, accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and oper alt-ed, and it will also be obvious that my invention is susceptible o't some change and modification without departing from the principles and spirit thereof, and for this reason i do not wish to be understood as limiting myseli to the precise arrangement formation or the several parts herein.

shown in cariying out my invention inpractice except as. hereinafter claimed. i
