- constructions, and arrangements herein de-- scribed and'claimed.

An object of m' invention is to provide a novel and effective device for operating doors consisting of a plurality of sections ,hinged together and foldable with respect to one another. A 'A further object of my invention is to provide a device of the character described that has means for locking the door in closed position and for preventing relative movement of the door sections until the locking mechanism has been actuated to release the door.

vA further object of my invention is to proto. the wal vide a device of the character described in which the parts are arrangedl for movement without binding and with very little friction, if any. A further Vobject of my inventionis to provide a device of the character described in which the/means for operatingV the door are arranged to connect with the latter at a plurality of separated points whereby a balced construction is produced.

A further object of my invention. is to provide a device of' the character described that is relatively simple in construction and operation, not likely to get out otl order easily, easy of operation, and thoroughly practical commercially. y

Other objects andi advantages will appear in tle following specification, and the novel features of the mvention will be particularly pointed out in the appended claims.

' My invention is illustratedin the accompanying drawings, forming part of this ap-4 plication, in wlnch- Fig. 1 is a front view of a in the invention, Fig. 2 is a section along the line 2-2 of i 1, y gig. 3 is 'an enlarged detail of a fragmentay portion of the device, igures 4 and 5 are enlarged details of a (see Fig.z1), and the plates 4 are secured by screws 5 or other suitable fastening means tothe upper sect1on 1 and project above the same. These bars or plates are connected by hinges 6 to a wa1l`7 in which an opening 8 is provided and normally lclosed by the door. The lower section 2 is provided with brackets 9 or the like secured thereto -by screws 10 to project laterally of the lower section adjacent its lower edge and these brackets carry wheels 11 each arranged to move along a vertical rail 12 that is secured 7 in any suitable manner as by means of `screws 13. Each rail consists of an Iangle iron positioned with one leg thereof at right angles to the wall, thereby preventing lateral movement of the section 2 while permitting the latter to be moved upwardly about its hinged connections with the section 1.

-A horizontally disposed rock shaft 14 is j ournalled in bearings 15 secured to the front side of the upper section 1 parallel with and adjacent to the lower end thereof..

The rock shaft 14 is fashioned with offset portions 16 and 17, these portions being located in different planes oblique to the section 1. A pair of cables 18 are secured at one end to the offset portion lwhich is intermediate the ends of the rock shaft 14 and consequentl in the vertical median line of the door. 'Ihe cables 18 Aare passed around an idler sheave 19 that is carried by a hanger 20 suspended from a ceiling 1 or other sup-' port, then around, a sheave 22 carried at the `end of a hanger 23, around a sheave 24,

around another sheave 25 that is carried by the hanger 23 adjacent to its connection at 26 to the ceiling 1, and are then merged into a pair of cables 8 and 29 which are preferably int-egral with the cables 18-18. The latter are conducted oppositely `around sheaves 30--30 throu h ide sheaves 31-31 ownwardly for connection at 32-32 with the brackets 9.

The sheave 24 is journalled in a frame 33 that is'carried at the end of a cable 34. The latter is passed around' and secured to a \thereoflmay be readily understood.

drum supported on a stand 36 that is se-v shaft 14 in position to occasion the engage-v ment of laterally turned lockingmembers 39-39 with keepers 40-40 that are secured tothe angle arms l2 as at 41.

From the foregoing description of the various parts of the device, the operatliilmie drum. 35 is adapted for connection with a suitable power device (not shown) and may be rotated at will to occasion the winding .of the cable 34 thereon or the unwinding of the vsame cable therefrom. IVhen the drum 35 is actuated to wind the cable thereon, the sheave. 24 will be moved inwardly or toward the drum, thereby exerting a tension on the cables 18 at a point approxii'nately inid- Way between the sheaves 22`fand 25. The tension or pull on -these cables is communicatedto the

cables

28 and 29 which are secured to the lower end of the lower panel .2 of the door. In the beginning, thev pull is exerted in the plane ot' sections l and 2 and consequently the

cables

28 and 29 will not be moved until the cables 18 have been moved sufficiently to rock the shaft 14', thereby causing the locking members 39-39 to dison the cables 18-18 and 28 and 29,

-7 is somewhat Vlower section 2 so that the latter may be v movedinto horizontal engage the keepers 40 -40 and permitting the adjacent ends of the sections l and 2 of the door to be moved outwardly about their hinged connections withone another. The force will then be distributed equally whereby the sections 1 and2 will be moved into the positions indicated by the idotted lines in Fig. 2. Itis to be noted that the distance from thelower edge of the upper panel 1 to the line of its connection with the wall greater than the height olithe i position without any .bindlng resulting. When "it is desired to close the doors, the oweractuated drum 35 is operated to permit-.the unwinding of the cable 34 and the doors will close by avity.

The means illustrated and descriedfor locking the door in closed position is that preferred by me particularly when vthe door is heavy in construction. Obviously, I may make use of other locking mechanisms, such as illustrated in the modified'fon-of the device shown inv Figures 4 and 5. f In that embodiment of the invention, I provide a plate 51 that is secured at 52 to'the -lower section 1 adjacent its yupper edge. The

'-plate 51 has integral upstanding lugs 53-53 integral with upturned sides 59-59 and" tween. A cooperating plate 55 is secured at 56 to the upper section 1 in alinement larly in the appended claims.

a', lroller 54 is mounted for rotation therebe- 4(51. The latter is passed beneath the rollers 54 and 58 and is normally maintained in the position illustrated in Fig. 4 by a spring (32. "Ihe latter is disposed between Vu lug 03 integral with the plate 55 adjacent its upper end and the'upper end of the locking bolt 61, whereby a tension is exerted on the latter that tends 'to force the same downwardly along the guidewa Only-one of the cables 18-18 is provi( ed and this` cable is secured to a lug 64 that is integral with the locking bolt 61.

The remaining parts of the modified form ol the device are identical in essential respects with the corresponding parts of the preferred form of thedevice and therefore require no further description. The same reference numerals have been used for like parts throughout the severa-l views. The operation of the modified form of the device will be readily understood, since the stress yon the cables 18-18 and 28 and 29 is first communicated along the cables 18-18 to the locking bolt 61. 'Ihe latter is moved from loc-king position and the sections 1 and 2 then permitted to move toward open position.k The pull on the cables 18-18 and 28 and 29 will then be equalized until the sections l and 2 have been moved into the position indicated by the dotted lines in Fig. 2.

While I have shown the vdevice as embodied ina door consisting of vertically .alined sections adapted to be folded vin a andmodilications of the for-mot the device i described in :the accompanying. drawings may be made without departing from the spirit and scope of the invention as described.v

in the foregoing and outlined more particu- 1. 'Ihe combination with a folding. door consisting of a plurality of hingedly connected sections 'arranged to be edgewise alined` inv a vertical plane when in closed position of la Vhorizontally disposed rockl shaft secured to the upper section of said door and being formed with locking members projecting laterally of the door, cooperating locking members secured at opposite sides of the door in position to be engaged normally by the first named locking members to hold the .door against movement from closed position, cables connected to said rock shaft intermediately and to the lower section of said door, and mean s, for operating said cables to release the door and to move the lsections thereof toward folded position.

2.' The combination with a folding door consisting of a plurality nected sections arranged to be edgewise alined in a vertical'plane when in closed position, of a horizontal rock shaft secured to the upper section of said door adjacent the lower edge thereof, and being formed with locking members at the outer ends thereof,

vsaid rock*A shaft having a, lever portion inof hingedly con-4 termediate its length extending'outwardly from said section, cooperating locking members secured to opposite sides of the door opening to be engaged normally by said first named-locking members, a cable connected .at one end to Said lever portion of said rock shaft, and at its other end to the lower section of said door, and means for moving said cable intermediate its length, whereby a pull 20 will be exerted at .both ends thereof.
