' 'Th e illustrated embodiment of my invention comprises a door consisting .of "two in the front wall ofthe'garage These two parts areas shown dividedin -a \'er ti-.

I .upon the inner surfaces respectively, of the 1 My invention relates to door-structures,

two parts so that the latter may swing so jamb by means of hinges 5. 5.;to the-garage j wall 3which forms the support for the. door structure. Thesehinges a'reso placed that this part1 m'av swing outwardly? as shown in; Fig.5. Abe, e the door opening and in a horizontal plane coincident with or paral 1 V V l el withjthe'lintelpisatrolleyjtraclrfi se- The annexed drawings and the followingv cured to the outer endsot brackets T, 7.

fin Figs. 4 and 5. This track'is also para'l- 'lel with the front wall 3' throughout the major portion of the width of 'thedoor opening, but. curves outwardly and-away. from the wall atthat pOrtiom-B", thereof which is adjacent to the. axisof oscillation formed by the hinges 5, the curve beginning at a point on one side of such axis and ending substantially opposite the latter, ,as-

shown. As shown in thegdra'wings this track is also provided w th a terminal portion 6 which is removed a distance from a .the .wall of the structure equal to the distance which the-outermost'portion of the curved 'part Of the track is 'remo 'cd. as"

clearly shown in Figsa tyand 5. This distance must be at least equal to thesum of the two doorthicknes'ses-plus the extent of outward projection of the {roller carrying bracket. v

The function of the. curve. inith'e' track is to facilitate the closing operation by bringing degree, the eifpctgof this curve:

the two pa'rts together gradually..-

exerted uponthe outer'fiange'of the rol er 10. The curve of the track may be said to roller and therefore the hangerand dooredge into'that course with proach of the two door parts will be made gradual and easy. The shape. of the track also controls the position of the two parts of the door after the folding is practically complete, that is, the flat open position of Fig. 6.

ecured upon the outer face of the other part 1 of the door and at the upper right hand corner thereof is a door-hanger member 8 'Which is provided with a bore 9 having a vertical axis, in which bore are seated rollers 10. These rollers form a bearing for cylindrical stem 11 forming the lower part of a trolley-frame 12, in which is suitably mounted a trolley-wheel 13. This wheel runs upon the track 6, as shown. The lower end of the stem 11 projects beyond the "member 8, is threaded and has mounted 'upon said threaded portion a nut 14 provided with a slot 15 through which passes a cotter-pin 16. Between the nut and the member- 8-is placed a washer 17. The position of the parts are such that the nut 14 will sustain the swinging endof the door, as will be understood.

A locking device is provided for securing the two door-parts to each other when the door is in its closed position, that is, when the two door-parts are in alinement, as shown in Figs. 1 and 4. This locking device consists preferably of 'a hasp 18 pivoted .upon a bolt 19 secured to one of the doorparts, and a staple 20 secured to the other of the two door-parts and passing through a slot 21 formed in the hasp. A strap 22 holds the hasp inplace when it is not on gaging the staple. The latter is formed with a shoulder 23, Fig. 3, and with an in clined surface 24 so that when'the two parts are swung into their closed position, the hasp will automatically-engage the staple, as will be readily understood. This hasp -is also provided at its free end with a loop door, and the twotparts of the latter assume an annular position with reference to each other, as shownin Fig. Further pulling upon the hasp, or if desired, pushing upon the right hand door-part 1, Wlll bring the upon each other. Further pushing upon the door will bring it" into the position shown in Fig.' 6 in which it is substantially parallel with the wall 3 of the building, with the trolley riding upon the part 6" of thetrack as shown in Fig. 6. It will be noted that in this position, theopen'door occupies only half the space laterally of the hinges 5 as is occupied by anordinar door which would berequired to close a similar opening.

To close the door, the above described operation is reversed,

Having fully described my invention, what I claim and desire to secureby Letters Patent is V Y 1. In a door structure, the combination of a suitable support; a two-part door, one part of which is hinged to such support and the other part of which is hinged to said first-named part; a hanger, .a track fixed with relation to said support and parallel 'with the latter throughout its major portion, the end portion being spaced from the wall a distance equal to the sum of the two door thicknesses plus the extent of outward projection of the hanger, and curved inwardly to connect with said major portion on a radius substantially equal to the distance of said end portion from the wall and about a center in line with the axis .of the hinged section, but in the plane of the track; and said hanger secured to said secondnamed door part, movable upon said track.

2. In a door structure, the combination of a suitable support; a two-part door, one part of which is hinged to such support and the other part of .which is hinged to said firstnamed part; a track fixed with relation to said support; and a member secured to sa id second-named door part, movable upon said track; said track for the greater-part of its length being parallelto the closed position of the door but being. curved outwardly from the support toward the. rear. said curved portion of the track being limited both in its length and in its projection transversely to the main portion to the. extent necessary to allow the door to assume its doubled and folded back position.

Signed by me, this 24th day of September, 1915.

THOMAS V. PLICE.
