" This invention relates to. a combined bracket and guides for rolling steel-doors. It has been difficult in making doors of this character to construct the same in a manner to prevent the wind pre'ssureexerted on the door to cause the ends of the same to be moved out of alignment with the vertical guides.
An object of my invention is to provide a guide for a rolling steel door anda bracket arranged at the top of the door opening in such a manner that the vertical guides will p-anying drawings in which in alignment with the guide channels.
always be in alignment with'the opening in the bottom of the bracketso that it is impossible for the door when being pulleddown from its rolled up position to strike against any obstruction on the guide channel.
Another object and feature of the inven-. tion is to provide a rolling steel door in which the vertical edges of the same cannot be moved out of the guide channel in which they slide.
Another object of the invention is to provide a rolling steel doorwhich is comparatively inexpensive in construction and which may be quickly and easily assembled in a suitable opening in a buildinga These objects and the several novel features of the invention are hereinafter more fully described and claimed, and the. preferred form of construction by which these objects are attained is shown inthe &CCOII1 Fig. 1 is a front elevation of my improved device. 1
Fig. 2 is a section taken on line 22 of. .Fig. 1. Fig. 3 is a'vertical section through several I width to permit the plates 4, forming the door 1, to be easily slidable therein.v It will of the interlocking plates of a door.
Fig. 4 is a detail perspective of one of the brackets used for holding. the edges of a door Fig. 5 is an edge view ofthe overhead bracket and one fof the vertical guides; the
door not shown.

Referring now to the drawings, the door 1 is arranged to close the opening 2 in the wall 3 of a warehouse or the like. The door 1 com- 1930. 'Serial' No. 462,356."
prises series of horizontally. extending -;v plates 4, thesame being in the formiof an S.
curve in cross section, as will be clearly understood by reference to Fig.3. a The upper and lower edges or theplates A arereversely rolled as indicatedatiiand 6- forinterlfocking relationship with the rolled edges of the next adjacent plate. As' will be understood by referenceto F igs.'3 and 4, an .Lshaped stop] is riveted adjacent'thevertical edges of the plates 4 and vso arranged that the portion 8 ofthebracket'? will closely abut the rolled edges 5 and 6 thus preventing the plate A from moving longitudinally-in relation to each; 1 i 65..
A second L shaped bracket riveted at;
10 to the outer edge of one of the plates 4. It
is to be understood that thebracketst) will be. spaced at suitable intervalsas it is not necessary to-have the same upon every succeeding platee. H
As willbe understood by referenceto Fig.
2, an angle iron 11 is secured to the angle.
of the rivets 14. It will be seen that the flange 18 of the angle iron 1 6 is in spaced relation to the: flange 19 of the angle iron 13 and achan nel-shaped member 20 isriveted at 21 to the flange 18 ofthe "angle iron 16'thus forming a.
shaped" member 2.0 and the flange 19 of the 4 space-22 between the base 23 of the channelangle iron 13. 'The space 22 isof suflicient be seen that the bracket '9 secured to the plates 4 will extend into the space formed between one flange of the angle 13. and; the adjacent q 3 leg ofthe channel 20' and willv be of sufficient width to prevent the plates flfrom being.
moved out of the space 22. It will be'clearly understood that since the plates i arekept from longitudinal movement in relation to each other due to the bracket 7 extending over the outer end of the interlocking edges and since the door 1is prevented from appreciable lateral movement being due to the fact that the bracket 9 secured thereto engages be-.
hind one ofthe legs of the channel 20, the door will maintain its position in relation to the guidechannels. i
, Referring now to Figs. 5,6 and 7, it will be seen that the bracket 25- has theflange 26 secured to one face of the building while a portion 27 of the said bracket is provided approximately centrally thereof with a hub 28 having the aperture 29 therein for forming a bearing for-a suitable shaft (not here shown) on which the door '1 may be rolled. It will be understood that there are two brackets 27 positioned at each side of the door opening 2. As will be seen'by reference to Fig. 6, the lower end 30 of 'the'bracket 27 is provided with an-L shaped groove 31. The portion 32 of the L shaped groove is of the approximate width ofthe space 22 formed between the channel 20 and the flange I i 19 of'the angle iron 13 and the space 33 is of approximately the same size as the space formed between the angle iron 13 and the ad'- jacent leg of the'channel '20. .A rib 34: is formed integral with the lower end 30 of the bracket 27 and is of a width less than the thickness of the flange 25 sothat a shoulder 'is formed by the rib 34 and the flange 25.
Byreference to Fig. 5, it will be seen that the shoulder 35 rests on the upper edge of the flange 19 of the angle iron 13 and that the base23 of the channel iron 20 is in alignment 7 its utility and' mode 'ofoperation, what 1' p with the flange opposite 'to the flange 30 on the bracket 25 and that the space 22 is in ali nment wit-h the opening 32 in the bracket 25 o that as the door is rolled up or down it will travel in a continuous unobstructed run romthe foregomg description it becomes evident that I have provided a rolling steel door composed of aseries of interlocking plates that are prevented from longitudinal movement in relation to each other and that the door as a whole-is prevented from moving out of the runways which guide both edgesof the door. i
-' Havingthus fully described myinventi'on,
claim and; desire to secure by Letters Patent ofth'e United States is- 1. Arollingsteel door comprising a series of interlocking plates, the interlocking means being such as to permit longitudinal movement-pf one plate relative to another, a
bracket mounted on the ends of one plate to engage over the interlocking end of another to hold theplatesfrom lateral displacement,
L-shaped guide channels at each edge of the of interlocking plates,
channels having an opening through which the plates may pass and having depending portions at opposite ends providedwith an L'-shaped opening therein in registration, at the lower end with the openings in the respective channels "and at the upper end being provided with a widened throat to permit the plates and brackets toturn in passing into the housing, a flange on each of said depending portions engaging the respective channelsto hold the same in alignment therewith, and a roller in the housing about which theplates are wound. V I I r 2. A rolling steel door comprising a series of interlocking plates, a channel at each side of the door opening to receive theedges of the plates, said channels being L-shapedin cross section, L'shaped brackets on the op posite edges of the plates riding in the brackets, a housing at the top of the door openinghaving a slot through which the plates may pass,=depending portions at opposite ends of thehousingfor registration with the ends of the channels and having an opening therein L-shaped in cross section through which the brackets and the edges of the plates pass in passing into, the housi11 and means on the said depending poru n a tlons engaging the respective channel to opening.
3. A rolling steel door comprising a series a channel at each slde of the door opening to receive" the edges of the plates, said channels being L-shaped in I cross section, vL-sha'ped brackets on the op posite edges: of the, plates riding in the brackets, a housing at'the top of the doorv opening having a slot through which'the plates may pass, depending portions atop- Tosite ends of the housingfor registration with the ends of the channels and having an opening therein eL-shaped in cross section.
