'1 15 the provision of anovel locking mechanism 111g from the nside of the doors show ng a w 'tofore referred to. The
Figure 12 is a detail perspective View of the said latch.
Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter B indicates a building, which can be considered of any character, or type, such as a garage, factory, or the like, having enlarged door opening 0 which can be closed by a pair of swinging andfolding doors D. As shown, each pair of doors D include an outer section 15 and an inner section 16 con nected together by means of hinges 17 at their adjacent edges. The inner door sections 16 of the pair of doors D are adapted to abut when the pair ofdoors are in their closed position. The outer door section 15 of each pair of doors are connected to the building B by means of strap hinges 18.
As heretofore intimated, my invention embodies novel means for facilitating the opening and closing of generally indicated by the reference character E, and novel locking mechanism which is generally indicated by the reference character F. v
My improved guiding mechanism E for facilitating the opening and closing of the doors comprises swinging arms 20, which are connected by means of pivot pins 21, with supporting brackets 22, which are connected with the building B directly above the door opening 0 thereof. A clearly shown there is a pivoted arm 20 on each side of the transverse center of the door opening, so that a guide arm is provided for each door ofthe pair of doors.
The arms 20 are of novel construction and are in the nature of guide tracks, as can be readily seen by referring to Figures 8 and 4 of the drawings. Thus, the guide arms 20 are of hollow construction and are provided with a longitudinal guide slot 23 in their lower faceand the walls of the guide slots can be struck inwardly to provide flared guide flanges 24, for a purpose which will be now described. Y Y 1 Slidably mounted within the hollow guide arms are the novel hanger brackets 25, each of which comprises a depending shank 26, which eXtends through the guide slots 23 in the arms. The upper end of the shank 26 is swivelly mounted within a supporting bracket 27, which extends outwardly from the opposite sides of the shank. The ends of the brackets 27 support pivot pins 28, on which are rot-atably 29. These side rollers 29 engage the inner face of the lower wall of the hollow arm 20 and abut against the guide flanges24, herebrackets 27 between the rollers 29 can be, .p'rovided with a circular head 30 which can fit directly within the guide slots between the flanges 23. The lower end of the shank 26 can be pivotally connected in any'desired way to angle door the doors, which means is mounted the side rollers brackets 31 which are bolted or otherwise secured to the inner door sections 16. From the description so far, it can be seen that each inner door section 16 carries a door bracket 31, and that the door bracket is connected to the novel hanger 25 which is in turn mounted on rollers within the hollow guide arms 20.
Thus, when the inner door sections 16 are swung outwardlythe same will swing on the hinges 17 and fold against the outer door sections 15 and at the same time the door sections 15 will. be swung open. This movement is transmitted to the door sections 15 and 16 through the medium of the hollow swinging guide arms 20 and the hanger brackets 25.
Referring to my improved locking mechanism F, the same embodies a novel locking or shuttle latch bar 35. This bar is mounted for sliding movement in supporting U- shaped guide brackets 36 secured to the building B directly above the door opening 0. The outer face of the bar 35 on each side of its transverse center is provided with arcuate latch arms 38, which are adapted to be moved into and out of engagement with the shanks 26 of the hangers 25 and it is obvious that when the arcuate latch arms 38 are in engagement i th said shanks 26 that the doors will be prevented from opening movement. Directly at the transverse center of the bar 35 I provide an elongated eye or guide loop 39, which receives the sharpened angular end 40 of the lock operating mechanism 41. v This lock operating mechanism 41 embodies a rotatable and a vertical sliding section 42, which section carries the angular end 40. The lower end of the section 42 is providedwith a sleeve 43 having a polygonal bore, which is slidably mounted on a polygonal shank 44 of the lower rod section 45.
The sections 41 and 45 are in direct vertical alignment and are rotatably mounted in upper and lower bearing plates 46 and 4'7 carried by one inner door section 16, it being understood that the upper rod section 41 also has sliding movement. The extreme lower end of the lower rod section 45 is provided with a crank arm 48 which extends through a slot 49 formed in the inner face of the inner door section 16. The lower end of the crank48 is provided with a depending latch arm 50, which is adapted to be swung into and out of locking engagement with a combined door stop and keeper plate 51.
The sleeve 43 has formed thereon or secured thereto a pair of pivot ears 52 to which is pivotally connected an operating handle 53, which is in the nature of a hasp for movement over a staple 54 carried by the adjacent inner door section 16 of the other door. The door section 16 carrying the rod sections 41 and 45 is provided with a vertical slot 55 having a lateral offset lower end 56 and the operating handle 53 normally projects through said slot. Normally, when the portion 56 of the slot 55, so -as to be out of the way and against injury.

The locking arm 50 at this ti me is in engagement with'the combined door stop and keeper 51 and the shuttle bar is in its locked positionwhen its arms 38 are in engagement with the shank 26' of the hanger. lius the-doors-are firmly engaged and locked.
Vhen it is desired to open the doors the padlock (no shown) -isf-emoved from'the stapleand the 'combined'hasp and handle a quarter of a turn, which retates the rod sections L1 and in their bearings. This swings the upper crank arm 40 and thelower crank arm 48 a quarter of a turn and moves the latch arm 50 from out engagement with the combined door stop and keeper 51. The swinging movement of the upper crank or offset pin 40, which is loop or eye 39 0f the latch its operative out of engagement with the shanks 26 of the hangers 35. The handle 53 is now pushed downward which slides the upper rod section 41 on the polygonal portion 44 of the lower rod section 415 and moves the offset pin or crank 40 fromout of engagement with loops or eye 39 of the latch bar. of doors are now free for swinging opening movement.

The outer sections 62 are connected to the door opening jambs by means of strap hinges 64. "The door sections 61 and 621are guided in' their opening and closing anovementiby means of novel swinging guide anm's 65, which are similar in their nature to the gui=de:arms20.
