MOV invention relates to doors and has special referenee to surh as are elevated sul)- stai'itiallr in the plane ot' the door opening?r hv snitalde hoistingr nierhanism and swing"- awa)Y vfrom the plane ot' the openingr at the, top on relatirelv stalionaiw' trark rails. l"nrtherinore. my intention pertaii'ls more partieuhllr to largel` hear)- doors whirh are adapted for warehouse. l'aetomY or like purposes.

(lne objet-t of my invention is to provide one or more track rails for a door of the aforesaid charm-ter with simple. and iinprored meansI for either supporting tho rails. suspending! the. door therefrom. or both. whereby the ope 'ation of the door 'is rendered prartieallv indepemlent of the. warping, settling or displacement of the. surrounding parts of the building.

Another ohjeetis to provide flexible and adjustable means for supporting a guide, track or tra'eks for a door ot' they aforesaid eharaeter, and means tor similarlyY suspendingr the door from the track.

Still another object is to provide a track and a hanger adapted to cooperate there with which shall hepartieularly adapted for supporting a door and which shall be arranged and constructed to preclude the pos- Sibilit)v of the hanger becomingdisengaged` from the track.

` Another object .is to provide. a three-point support for a door whieh is arranged to swingt away from the. door opening at the top and han a pair of hoisting chains eonneetecl at its lower corners whereby7 the door is free to adjustitselt' without being suh- :jeeted to warping strains.

Another object is to provide. a top support for doors,I of the aforesaid character thatl I@li-all. permit the door to rise, Somewhat. in a vertieal plane before. it swii'ige away from the opening` thereb)v enabling it. tn swing inwardly without an)r tendency to put, Strains upon the top lguide and Support.

ltet'erringto the dra wings:

Figure l is :l set-tional elovallon o f a dOOl arranged and equipped in accordance' with inw invention and eonstitnting an embodilnenl thereof. i

Fifa'. 2 is a partial l'ront elevation ot.' the suspension ineehanism showing the traek rail in ('l'oss settion.

Figs. Il and -l are News' eorrespondingI t0 Fig. 2. showing modified hangers wint-hills() einliod)7 in)r invention.

Vig'. 5 eorresponds to Fig. it' shows a pair of rails and hers e|nplo \'ed with a single Still another inodilieation is, shown in Fig. (l whieh corresponds to Figs. 2. il and l. Init comprises a fixed rail or rails trom whieh the door is suspended.

Fig'. 7 is a moditeation of the arrange,- nient o'll Fig'. t3 in which n pair of lz'lils are employed. spared apart hy a distance substanfiall)l equal to the width ot' the. door.

Figs, S and 9 show still further modifications ot' my invention and eorrefspond to a portion ot' Fig. l.

Details of the suspension strueture of Fig. l. are shown in Figs. v10 and 11, and the pivotal mountiim` ot' the rail is Shown in plan in Fig. l2.

In Figs. 1 and i2, 15 designates one of the door poste. 16 the lintel and 17 a ceiling l'ieam extending inwardly away from the plane ot' the door opening,

Suspended from the ceiling beam'l? by 'a pair ot' adjustable links 18 is a relatively stationary track lail 19. .As shown in Fig. 2, thisl rail ma)Y eomprise an I-beam of well known form with whieh a pair 0f frustloeonieal rollersl 20 are adapted to eoperate. lt is furthermore preferablyjoined to the lintel at its inner end by means of aslidable pivot lil" to permit freedom of movement as t'ar ils-.allowed l the suspension links. (Seel"ig "s. and 12.) The rollers are mounted on a Yoke or elers 21 so that they are on opposite sides; of they trat-k.

The door, which maw7 haa'e one or more seetions. eomprises. in the. arrangement shown. an upper door section 92 having `uidewaw's 24. and a lower door section 25, haring guide rollern 2G near it# lower COI- exeept that suspension memdoor.

of my invention i in any suitable manner; for example, they other hand be supported in fixed may comprise a pair of bolts 29 and 30, joined by a turn-buckle 3,1.

The link 28 ma be similarly constructed, or, as shown in tlie drawings, it may comprise a pair of nuts .or sockets 32-33 joined by a stud 34 having oppositely extending left and right hand threaded projections 35.

At the inner end of the rail 19 I prefer to utilize wedge-shaped blocks 36, one of which is shown, for the purpose of starting the rollers 20 away from the plane of the door opening when the up er door section is first forced upwardly by t e hoisting mechanism.

Instead of links 18 and 28 of Fig. 2, chains 38 and 39 may be substituted as shown in Fig.` 3, or the adjustment of the length of the link may be obtained by vother means, as, for example, that shown 'in Figs. 4, 10 and 11. V

As yhere shown, a link 40 replaces the link 28 of Fig.4 2, and for the linksl 18 is substituted an adjustable link 41, composed of a member'42 having a plurality of holes 43 and a`member 44 havin a slot 45. The

` members are attached by olts 46 which extend throu h one or more of the holes 43 and tliroug the slot 45.

Instead of'utilizing a single tra-ck 19 and a single hanger as in the arrangement of Figs. 1 to 4 inclusive, two or more rails or han ers may be employed as shown in Fig. 45. ach of these hangers corresponds to that of Fig. 3 in the arrangement illustrated, but of course any suitable arrangementmay be utilized.

In the modification of Fig. 6, a pair of channel shaped suspension rails 48 and 49 are employed. `These rails may be close together as in ig. 6, or spaced at considerable distance 'apart as in Fig. 7. They may be suspended as in the previous figure-s, `but this is not. essential and they may on the position by: any suitable means.

A pair of rollersl 50 and 5l cooperate with the respective rails und are mounted near the. respective ends of u shaftl In the arrangement of Fig. 6 a sleeve. 53 spaces the rollers apart and is coniufcted to the. door bracket 27 by hinge block 8T and link 40 as in the arrangement of Fig. 4.

In the structure of Fig. 7, the shaft 52 'turc itself.

is of considerable length and a hunger 54 is pivotally mounted upon it near its middle ioint. beinglicld in position by collars 55. 1` he hanger is pivotally connected to the hinge block 87, the arrangement of parts being such that the hanger 54 permits the door to swing in one plane and the pivotal connection between the hanger andthe hinge block permit the door to swing in another plane.

If the rail 19 is sus ended by links 18 as is Figs. '1 and 8, the coor may have rollers such as rollers 56 mounted on door brackets 57, the brackets being rigidly attached to the top of the door as shown in Fig. '8.

Another modification in which a stationary rail 58 is provided is shown in IFig. 9; The rollers 20 of the yoke 21 'are connected to the door by a chain 39 as in Fig. 3.

Any suitable hoisting mechanism may be employed such as that shown in Fig. 1, for example, and designated 61. This mechanism comprises counter-weights 62 suspended byl chains 63 which extend over pocketsheaves 64 and are connected to the lower door section 25 by corner brackets 65. It further comprises a hand chain 66 which may' be actuated in the usual manner.

section, this section is first.-raised and voverlaps the upper section 22; upward pressure is then applied to both sections together and temporarily a force is exerted through the link 28 which tends to push the roller 20 into engagement with the inclined cam surface. of the bracket 36. This action assists in breaking in" the door at the top and as the hoisting is continued, the upper end of the. door swings inwardly, the rollers 2() riding on the rail 19 until the door occupies'the 110 position shown in broken lines in Fig. 1.

0f `course-'the bracket 36 may be omitted and will be of. no vu lue .when chains or flexivble Suspenders such as the chains 39 are employed.

Attention is particularly directed 'to the fact that the guidt` and supporting rail itself or the connection `between the rail and the door, or both. are yielding structures, or, in other words, they permit a material freedom of movement and thus not only relieve the door from stresses and stra-ins which tend to warp and twist il. but also largely eliminate strains upon the. supporting struch Thisl yielding ot the supporting rail is also facilitated b v the pivotal or hinge connection which is establishedbetween the rail and its end support: for example, the arrangement clearly shown in Fig. 8 permits the rail l!) to rise somewhat 130 when the dooris first hoisted as well as to swing about the pivot as 'an axis to follow 'tending to interfere with its operation.

Further modlfications. will suggest themselves to those skilled vin thisl art, .and I intend that no limitations be imposed-jo'ther-A than those indicated in ap-pencledelaims.

What 'I claim is:

1. The combination with a door frame and a rail extending inwardly above the, door opening, of a door, hoisting means therefor acting substantially in the plane of the door opening, and means movable in relation to the rail for suspending the door from the rail, said suspending means comprising a non-rigid connection.
