6v claims; (c1. iss-'57) This invention .relates to improvements in doors, and particularlyy .to rolling doors Vsupported so that the .door maybe moved to and froma doorway in axwall.v l

It; is` also. an robject ofthis invention to pro.; vide a vdoor witlran opening: therein, and a closure for the opening, said door and closure being independently' supported and operated.l

It is ,Y also an object of this invention to. provide a rolling door supported by means of a drum for moving the door to and from a doorway ina wall. This ldoor 'is provided with an openingandna closure for closing the opening, said closure being supported for movement with relation to the door and operated. simultaneouslyl with .but independ# ent of the door.

)Theseand other advantages will; appearirom they followingdes'cription taken in connection with thedrawings.. v f Referring. to the drawings:

Figure 1 is a front elevation of the door, showing its supporting and. operating mechanism and the .guard therefonwith `the guardA and vthe door partly vbroken away.` 1

`Figure 2 is a side elevation of the door and the closure supporting an operating mechanism.

' Figure 3 is a section on the line. 3-3 of Figure 1.

Figure 4 is a section similar to Figure 3, showing the door-and the closure in elevated positions.

Figure 5 is a section on the line V5--5 of Figure 3. f The present door Vis adapted to be used in connection with variousftypesV of buildingsior closing doorways therein. The. numerallI indicates the wall of a building, such as a garage, warehouse or zotherlbuilding. .In this wall is a doorway 2 adapted to be closed by the door, the subject-matter of this application.

On each side of the doorway and supported by the wall is an angle iron 3, which has one arm suitably attached to the wall, while the other arm` projects from the wall at right angles thereto. Spaced from the angle iron 3 is an angle iron 4, which has one arm attached to the wall and the other arm extending from the wall parallel to an arm of the angle iron 3. (Figure 5.)

Between these two angle irons is a space 5, into which projects one arm of an angle iron 6, one arm of an angle iron 'l and a spacer block 8, which holds the angle irons 6 and 1 in a fixed position between the angle irons 3 and 4. The other arms of the angle irons 6 and 'I form a groove or space 9, in which one end ofthe door composed of sections I0 ts and is guided.

The door sections have their opposite edges II looped with adjacent edges, interengaging for the purpose' of 4supporting the sections inhinged-relationship `with one another. The upper edge of the door is supported by lmeans of a drum I2, which may be rotated for elevating or'lowering the door as the caseimay be. This drum is supportedjby means of brackets I3, one at each end of therdru'm, supported -bylthe wall. On the lower edge of the door for engagement with the ,oor of.. theV building to which the door is applied, an angle iron strip- I4 ,is attached. (Figures 1 and 3;)

The doorlfis provided with one or more openings'IE. At each endf of each opening the door is strengthened bymeans of -a strapl. On each end. of the drum isa shaft Il, which serves to support the-.drumin bearings provided thereforinjthebracketsi'l3. On oner shaft Il 'is a gear I8, whichmeshes with a gear ,20, located on a shortyshaft I9 also supported by one of the brackets I3.

' On lthis shaft` I9 is a sprocket' Wheel '2i over which-passesra sprocket chain 22 for rotating the gearI I8y and the drum I2.v There is also provided on" the :bracket I3 a guide 23 for the sprocket chain.` The'openings in the door are closed by means of panelsconsistng of a frame 24, with panes of glass 25 therein.

z As shown iii-Figure ll ,thelclosure is in a position to closethe openings in the door, and is sup- .portedin position by means'oi chains or cables 26. Each `chain" or cable isy attached at one end to the lower edge ofthe closure,` while its vupper end isattached toa drum 2l located on one end iofnazshaft .28 supported by means of abracket 28u, supported on a guardll'L y A On one end of the shaft '28 is a pinion 29, which meshes with the gear I8 so that as the door is operated to close or open the doorway the panel is operated to open or close the opening in the door. The guard 30 is attached to the wall above the doorway and serves to pro# tect the drums and the shaft 28 from dust and other foreign materials.

The channelways 3I, which guide the ends of the closure, continue upwardlyk above the doorway and form housings 32, in which the ends of y the closure rest when the door is open. These housings are at the back of and. above the guard 30, the guard having an upwardly extending part 33 connecting the two housings so there is formed a complete closure for the panels containing panes of glass.

In Figure 1 the door is shown in a closed position. In order to open the door the sprocket chain is operated so that the drum rotates to wind up the articulated door. At the same time the shaft 2B and the drums are rotated so that the closure is moved with relation to the door. This closure is moved vertically upwardly so that it will be housed behind and above the drum on which the door is rolled.

When it is desired to close the door the sprocket chain is operated in the reverse direction, lowering the door and at the same time lowering the panel which closes the opening in the door. On account of the pinion 29 being smaller in diameter than the gear I8 the closure moves at a greater rate ofspeed than the door, and during the opening and closing `of the door moves at a speed different from that at which the door is moved.' The closure is sup'- ported and operated independent of the door, the connection between the ktwo being the gear i8 and the pinion 29, and the common actuating mechanism.

I vary the speed by' varying the spool size of 21 and thereby adjust the exact location of the closure 24, depending upon the height of the opening it is to close.

It will be understood that I desire to comprehend within my invention such modifications as come Within the scope of my claims and my invention. i v

Having thus fully described my invention, what I claim as new and 'desire tosecure by Letters Patent, is:

l. In a door structure, a door composed of articulated sections and having therein an opening, a light transmitting closure for the opening, means to support and elevate the closure, means to support and roll up the door, and operativelyinterconnecting means to operate both of said means in timed relationship at the same time substantially throughout the period of closure of the door.
