FOLDING DOOR. i
To. aZZ `whom t may concer/n.'
` Be it known that I, Enwaiui H.' MoCLoUo, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful In'iprovement in Folding Doors, of which the following is a specification.
This invention relatesl to that kind of folding door wliichis divided horizontally into sections the object being to simplify their construction and promote their ease of operation and increase their eiciency.
The invention. is embodied in the construc tion herein shown. and described and then pointed out in the claims.

Specication of Letters lratent. i Patented Sept, 17, `191 `8, Application led April 15, 1914. Serial No. 831,945. l
Referring more particul-.irly to Figs.. l to l0 the character 20 designates the lower door section and 21 the upper door section. The lower door section is shown Vas iliade about twice the height of the upper section. The lower door section is provided at each of its lower coi-11ers with a large anti friction roller 22 that travels on one web of an angli.l bar 23 that is seiifiired vertically to the adjacent face of a wall 2l that has the door vinclined groove 28 and oneach side of the lower door section is a pin that projects into said groove when the door is lowered. Said pin can be provided with a small antifriction roller. The function of the groove 28 and pin :Z9 is to projectthe upper end of the lower door section inward or away from the door opening when that section is raised in the operation of opening the door. This pin 29 can enter a `keeper 29"'when. the door is lowered to further lock the door' againstthe opening. n
The upper door section is hinged at 30 to" the building near lthe ripper edge of the doorway. Hinged to a bracket. 31 on each! lower corner ot' the upper section a hinged arin having jourualed in its outer enda roller 33 that normally bears upon the inner' face of the traine of the lower door section to cause the lower section to draw out the lower portion of the upper door section when the upper portion ot the lower section 1s thrown out b v thegrooves 28a. bracket 31 is provided with two separated arm 32; and on the outer side of the lower v door section near the middle horizontal. line l thereof is a 'hook 2Min vertical aflinement with each of said bridging hinge pins 3:2"` so that when the lower door section is raised j said hooks 3% catch said bridging pins and ,hingedlyi connect the sections.
34 has a lateral extension 34 and the bracket 31 has a. vmatching extension 43l" thatgflaps i over the extension 34 when the doei' is broken or iexed and the sections stand at considerable angles to each othei so that these hinging members and the door s ections are locked from accidental separatlon or undue movement with reference to each other in the further operation.
The means shown for raising the lower section (and consequently the u pper section) consists ot' a pair of chains 35 and 35 connected with the lower corners of the lower door section and ruiming over su1table pulleys to a counter-balance weight 36 that slides in a box vertically secured at one side of the doorway` Sin-all doors might be operated by the application of the hands to the lower door section but with large or heavy doors si'litable reducing gearing operating sprocket or pocket wheels for moving appropriate chains 35 and 35 as suggested in Figs. 1 and 2 can be enqloyed and said gearing and sprocket or pocket wheels operated by a sprocket wheel 36"* and an endless chain 3T ruiming thereover. Such inealis, however, are. connnon and require no detailed description here.
In thevconstruetion illustrated in Figs. 1 2 and 23 the door, if large, may be raised a part of the way only-as where persons only are to pass under it., but if much head rooni is desired or required as where loaded vehicles are to pass under the door. the sections are fully raised. In Fig.y 3 the door sections are shown by broken lines in the two positions just referred to. In the construction shown in these views the sections when completelyY raised come foldinglv or parallelly together and stand horizontally7 from the wall. ln such horizontal position a support for the outer edge of the projected door may be important. Such a support is shown in Fig. it and' consists of a bracket 38 fastened to the ceiling or beams thereof and having a seat 38 to receive suitable. casters or rollers 39 secured for this purpose to the edge. of the lower door section. As before indicated the path of movement of the upper edge of the door section is illustrated in F ig. 10, said path being indicated b v the heavy black line leading fromthe roller 39.
Referring now to Figs. 11 to 1st inclusive the construction of the door generally is substantially the same as that-first described.
.But the upper door section in the modified construction is provided at its upper edge with brackets 21 extending upward beyond the door .opening each for the reception of the leaf of a hinge. 30 by `means of which the upper section is in operative eltect made 'of practically the same height as the lower section'. iVhen the lower door section of this modified construction is raised unt-il its lower, edge coincides .with the top of the doorway or opening. or in horizontal posi- I imams tion, the upper door section sustains thc outer portion of the lower door section and no additional supporting means such as the bracket 38 is required. A construction like that shown in Fig, 13, however, requires lnore head room for the installation oi the door than a construction like that shown in Fig. 3.,?'111 the construction shown in Fig. 13 the hooks` 34 are shown as placed nearer the upper edge of the lower door section so that the connection between the two seetions is nearer the edge of the lower door section when extended in horizontal position (sce broken lines upper portion of Fig. 13) thereby affording a firmer support t'or the door section when raised to horizontal position. The upper section. of course` braces and amply supports the outer portion of the lower door section in all the substantially elevated positions of that section because of the angular relation ot the upper door section to the lower.
The path of movement of the upper edge of the lower door section in the construction shown in Fig. 13 is illustrated by the heaviY line leading from said section in the plotting shown in connection with Fig.'14.
The forms of the, parts shown can be varied and a part. or parts omitted or'sonle parts can be used in conjunction with other and different part or parts without departing from the gist of the invention as finallv claimed. i
