In this descrip- Fig. '7 is a perspective detail of the hardware 55 tion only the parts on the right hand side of the door will be described. It is to be understood, however, that these parts are duplicated on the left hand side of the door, where they operate in exactly the same manner.

Attached to the door section I9 on each side, at a point slightly below its uppermost edge, are angle brackets 32 shown in detail in Fig. '1. The long leg of each angle bracket lies adjacent the inner face of the door and the short leg 33 lies adjacent the edge of the door section.

Pivoted to the short leg 33 upon the rivet 34 is the swinging bracket 35. The bracket 35, as shown in Fig. 7, is composed of a metal strip formed into a long arm 36, and then bent to form the arm 31 perpendicular thereto. The arm 31 is again bent at its outer end to form the ilange 38 which is perpendicular to the arm 31 of the bracket 35, and parallel to the long arm 36 thereof.

While one end of the long arm 36 of the bracket 35 is pivoted to the angle bracket 32 at the pivot 34, the other end is provided with a rivet 39 which forms a pivot for the free link 40 and also serves as an axle for the wheel or roller 42. Afxed to the link 40 is the rivet 4I which serves asan axle for the wheel or roller 43, as shown in Fig. 5.

Pivotally attached to the ange 38 of the bracket 35 is the vertical rod 44 shown in Figs. 1 to 6, inclusive. 'Ihis vertical rod 44 is guided by the ring bolt 45 through which it passes. The ring bolt 45 is secured to the uppermost section I of the door. The vertical rod 44 is broken and provided with a pivot 46 by which the lower portion 41 of the vertical rod is pivotally secured to the upper portion 44. This pivot is so placed as to be in alignment with the joint at which the door sections I0 and II meet, when the door is in position to be opened.

Below the

rod

44, 41 is the toggle 43, 4S. The upper end of the link 48 of the toggle is joined to the rod 41 by the pivot 53. The lower link 49 of this toggle is pivoted at 56 to the door section II. stricted and guided by the arrn which is pivoted to the door at 52 and to the pivot 53 which joins the rod 41 and the upper link 46 of the toggle. The lower link 49 of the toggle is pivotally secured to the operating bar 54 at the pivot 55. The operating bar 54 is also secured at its other end to the rotatable plate 56 and is slidable within the guide 51, which is secured to the door sectionl I I.

The rotatable plate 56 is operated by the handle 58 and can be locked in the position-in which it is shown in Fig. 1 by the conventional lock 59.

The operating bar 54 projects beyond the pivot 55 suiiciently far so that it may be projected through a slot in the remote rail of the vertical angle beam I9 and serve as a bolt to lock the door in closed position as is shown in Fig. l.

The door may be provided with an auxiliary sliding bolt 6U, mounted upon the rear face of the door, which can be slid through a slot in the remote rail of the vertical angle beam I9 to lock the door in closed position when the uppermost section I0 of the door is swung into open position. Similar provision may be made for locking the door in closed position by providing a hole 6I in the face of the vertical angle beam I9 through which a bolt may be projected to engage the bearing member assembly which is shown in detail in Fig. 8. Any other suitable means may be employed to bolt the door against upward movement when the uppermost section I0 is held in open position.

The door may also be provided with a suitable handle 62 by which the door may be raised and lowered.

The operation of the door is as follows: When the door is in closed position as shown in Fig. 1 the bearing for the uppermost section l@ is in the position illustrated in Fig. 5. The long arm 36 of the bracket 35 projects horizontally from the vertical door section and the wheels 42 and 43 lie upon the flat rail of the curved portion 20 of the angle beam I9 upon which the bearings of the door ride. The front of the frame member 63 of the door section I9 is borne against the stop I1 below the lintel I5. The arm 36 of the bracket is held in the horizontal position by the vertical rod 44 which is operated through the intervening links by the operating bar 54.

When the parts are in the respective positions illustrated in Fig. 5 the door cannot be raised, because the upper edge of the door section I9 bears against the sill' I5 and the pivots I8 and 46 do not coincide and because the remote end of the operating bar 54 projects through the vertical rail I9 and bolts the door in that position. When it is desired to open the door, whether the uppermost section I0 is alone to be swung open to provide ventilation or the entire door is The range of movement of the toggle is re- Y.

to be lifted into its horizontal position beneath the ceiling of the room, the lever 58 on the rota-table plate 56 is swung toward the right. Because of their eccentric pivotal mounting upon the plate 56 the horizontal bars 54 are moved toward the middle of the door and their ends withdrawn from the slots in the vertical rail I9.

Simultaneously, the horizontal bars 54 swing the lower links 49 of the toggles about their pivots 50 and the toggles are opened as shown in Fig, 2. The toggle is guided into an almost vertical positon by means of the pivoted bar 5|, which swings about its pivot 52, and restrains the toggle so that the links of the toggle assume practically a vertical position. The horizontal motion of the -bar 54 is thus translated into vertical motion of the

rod

44, 41, which is pivoted to the ange 38, at the end of the long arm 36 of the bracket 35.

As the rod 44 moves upward it closes the angle between the long armV 36 of the bracket 35 and the edge of the frame portion 63 of the uppermost section I0 of the door. As the bracket 35 is restrained by the engagement of the wheels 42 and 43 with theat rail of the curved portion 20 of the angle beam I9, the closing of the angle between the bracket arm 36 and the frame portion 63 can be effected only by the swinging inwardly of the uppermost section I0 of the door about the hinges I8, by which sections I0 and II are connected. The uppermost section I0 of the door thus swings rearwardly into the room which is yclosed by the door, and the upper part of the door frame 63 comes to rest on the arm 31 of the bracket 35, which limits the extent of movement of the frame '63 and serves as a carrier for the uppermost section IU of the door. At the completion of this movement the parts shown in Fig. 5 assume the relationship shown in Fig. 6. The relation of the parts in this position is also shown in elevation in Fig. 2 and in sectional elevation in Fig- 4.

It is to be noted that when the vertical rod 44 is projected vertically, the pivot 46 by which the rod is joined to its lower portion 41 is aligned with the hinges I8 at the junction of the door sections |||Y and Il, thus permitting the rod 44-to break at the hinge and-v swing rearwardly with the upperI door section l0. -This is best illustrated in t-he sectional detailin Fig. 4'.

f With the parts in the positions shown in Figs. 2, 4 and 6, the door may either be locked by throwing the bolt 60 through a slot in the vertical rail I9 or by projecting a bolt through the hole 6| in the face of the rail I9, into the path of the bearing assembly mounted on section I2 of the door.

If it is desired to open the entire door after the uppermost section has been swung into the position shown'in Figs. 2, 4 and 6, the bolts just described can be released andV the doorA can be manually lifted bythe handle 62 with the aid of the springs or counterweights which may be connected to the cables 23.

As the door is lifted the Var-ious bearings will ride upon the angle rail I9 about thev curved portion 20 and iinally upon the horizontal portion 2| of the rail aixed to the ceiling. The upper frame-piece 6 3 of the uppermost section I0 of the door is borne upon the arm 3l of lthe bracket 35 and the entire door section Ill is thus carried upon the wheels 42, 43 mounted upon the bracket 35, both about the curved track 20 and throughout the horizontal travel of the `door upon the tracks 2|. The entire door can thus be rolled around the curve 20 and into a horizontal position. No clearance of any kind is required above the door and the rail 2| may be mounted beneath the ceiling of the room and spaced from it by merely the thickness of the door.
