SHEET-METAL DOOR.

Application filedk November This invention relates to sheet metal doors and its objects are the provision of a generally improved and simplilied sheet metaldoor construction` that may be economically produced. Y

, The construction is characterized by facility of erection. It may be easily and quickly assembled Without the usey of rivets, bolts, or the like. rlhe stile and general 'frame construction are standardized and the construction of the rails, panels and other parts are also standardized. and interchangeable, so that the doors nay be conveniently erected with dii'lerent panel and rail.arrangements More particularly, the invention provides an improved stile strueture,; an' vimproved panel and rail structure and an improved mode of attachin` the panels and rails to the 'trame or stiles.

Further features are the manner of iorm ing and attaching: the panel molding and the manner Ot providingthe door with hangers, guide means and iiller means, Where'desired. rlhe hanger means may be adjustable to eX- pedite proper hanging' of the door in spite of settling and such structural variations as may occur. n

My improved sheet metal construction has a wide range of utility. l contemplate its employment for the onstruction op? elevator doors and the like. A. door construction ein'- lrmlying my invention has all the advantages oli lightness and strength and, in addition, is tire and substantially sound prooi.

Referring lirst to Figs. 1'to 10, the door comprises stiles 5,6, a. top rail (l, an intermediate rail 7, a `bottomrail 8 and panels=9 and 10..l j f The stiles may be kformed of sheet metal ,i

suitably shaped into generally' rectangular hollow yconhguration in transverse section as the intermediate rail mem- .y

shoWninFig's. 8 and 4. Along one side of the i door eachstile has alongr its inner edge a tongue 12'turned back` and lyingfiin the direction of the thickness ot the door. Along the vopposite side oil thedoor each stile' has a tongue 14turueil back and lying in the direction oil the width ol.k the door; The inner corners ol each stile 5 between vthev tongues 12 and'14, are open at 15, and closing and The upper rail 6 eomprisesa pair/of rail members land 26. The rail member 26 has laterally extending tabs 27 Oi'lset at Q8 and turned back to formtongues 29 which en,- gage and interlock with the tongues 14 on the stiles 5. In erecting the door, the upper rail is adapted toY be installed.by'interlock- Y `engagement therewith.

ing the tongues 29 with the tongues 14 and sliding it down until its upper edge comes substantially flush with the upper edges of the stiles 5, as shown in Fig. 1. The main surface of the rail member 26 may be disposed substantially flush with the adjacent sides of' the stiles 5.

The upper rail member may be oflfset or turned out at 32 to dispose the rail wall 33 substantially flush with the opposite sides of the stiles 5. rlhe inner odge of the offset or inturned portion 32 has a marginal flange 35 which is adapted to engage and interlock with a turned back tongue or flange 36 along the adjacent edge of the rail member 26, and the wall member has lateral flanges or tabs 34 turned in to fit or be sprung between the inner edges of the stiles rllhe upper ends of the tongues 12 and 14 and strips 16, terminate short of the top of the door, and extending between the upper rail members 25 and 26 and between the opposite sides of the stiles 5 across the width of the door from one side to the other is a channel member 38. The channel member 38 opens upwardly and the upper edges of' its vertical legs may terminate flush with the upper edges of the rail members 25 and 26 and stiles 5. Theflanges of the channel member 3S may be spot welded or otherwise suitably secured at 40 to the adjacent rail and stile portions of the door.

The central or intermediate rail 7 comprises a pair of rail members 42 and 43. The rail member 43 is similar to the rail member 26, having laterally extending tabs 44 offset at 45 and turned back to form tongues 46 for engagement and interlocking with the tongues 14 of the stile members 5. The main surface of the rail member 43 may be disposed substantially flush with the adjacent sides of the stile members 5 and the rail member 42 may be turned out to dispose its main wall substantially flush with the opposite sides of the stile members.

The rail member 42 turned in at top and bottom at 48 and 50, respectively, and these turned-in portions 48 and 50 terminate in marginal flanges 52, which marginal flanges 52 are adapted to engage and interlock with turned-back tongues or flanges 53 along the opposite edges of the rail member 43. `In erecting the door, the central rail may be assembled by slipping the rail member 42 transversely into proper interlocking engagement with the rail member 43 before slipping the rail member 43 into assembled position between the Stiles 5 and into interlocking The interlocking flanges 52 and tongues 53 bind the intermediate rail members together and against sidewise displacement relative to each other and the engagement with and between the stile members binds them firmly therebetween and against endwise displacement.

Where a sheet metal, such as a steel panel,

is employed, it may comprise a sheet of proper ga ige provided along its upper and lower edges with turned back flanges or tongues 56 and 57, respectively. ln erecting the door where a panel such as this is employed, the panel may be slipped transversely into interlocking engagement with the rail members before the portions of said rail members, with which the panel interlocks, are slip] ed between the stile members of the door, so that when the rail members are interlocked with the stile members and slipped into proper position therebetween, the rails, stile members and panels or" the door will be firmly secured into a unitary sheet metal door structure.

rlhe edges of the panel may be finished by a molding 62. composed of vertical and hori- YZontal metal molding strips fitting within the frame provided by the stile and rail members. The molding strips have inturned marginal flanges 63 terminating in beads 64. For the purpose of securing the molding in place, a plurality of suitable clip members 65 are provided. These clip members have flanges 66, which are adapted to be inter-engaged or iuterlocked with the tongues 14, 36 and and held in place with the other flanges or tongues interlocking with said flanges or tongues 4, 36 and 53.` utwardly of the flanges 667 the clips 65 are offset at 63 over the outer surface of the panel. The odset portions 66 terminate in tongues extending outwardly and turned back at 70, and the beads 64 of the flanges 63 of the moldingr strips are adapter to besprung` beneath or behind these turnedback tongues 70 to hold the molding strips securely in place.

The attachment clips 65 for the molding strips, may comprise relatively short lengths placed as desired about the stile and rail members to hold the molding in place, as shown in 5. The abutting corners of the molding strips are preferal'ily beveled or mitered. and these corners m ay, upon completion of the door. be welded together.

The lower rail member 8 is shown as formed and interconnected similar to the upper rail member 6. lt comprises a pair of rail members 7 6 and 78, the rail member 78 having lateral tongues interlocking with the tongues 14 similar to the tongues 29 of the upper rail member and a turned back flange or tongue 30 along its upper edge for interlocking with a flange 32 along the upper edge of the rail member 76 ano with the tongue 83 along the lower edge of the panel 10. EX- tending the width of the door and secured between the lower edges of the rail members 7 6 and 78 and the opposite sides of the lower ends ofthe stile members 5, is a channel member 85. The channel member opens downwardly and its flanges may be spot welded or otherwise suitably secured at 36 to the adj acent rail and side or stile portions of the door.

In the door shown in Figs. 1 to 10, the bottom panel 10 may be similarly secured in place and similarly finished with a molding, that is, like the upper panel 9, so that a further detailed description ol the same is bclievedunnecessary. Upon the completion ot the door, the opposite ends ot' the upper intermediate and lower rails 6, 7 and 8, may be welded to the adjacent portions of the stile members 5, and the entire structure thereby joined into a solid, unitary door having great strength.

rllhe lower channel member may be provided with suitable guide pins 88, formed ot cast iron, or otherwise, as desired, and suitably secured in the channel 85.

For hanging the door, the upper channel member 38 is provided with suitable hanger blocks 'secured therein by screws92, which the blocks 90 have internally threaded open-` ings 92 for hanging the door. rlhe hollow stil-e members 5 may be provided internally .with 'suitable fillers 911. rFliese fillers 94 may be of cork or other suitable material.

ln Fig. 12 the door is shownL as provided with a glass or suitable transparent/panel 100, which may be substituted for the upper panel of the door or" Figs. 1 to 10, or be otherwise placed therein. In this case, the pane is cut or dimensioned to lit between the stile members 5 and 'the rail members ot the door, with their inner surtaces seatingupon the inwardly exteiiding flanges 86 or' the `rail iii-embers and the inwardly extending a panel. may be substituted "or either or both et the panels of the door alreadydescribed, or it maybe otherwise interposed in the door, as desired. It may be mounted and secured in place, as is the panel or pane 100 ot Fig. `12, or otherwise as desired.

ln the door shown in Fig. 11, the central or intermediate rail of the previous embodiment is omitted and a single panel 106, sur rounded by stile members 107 and upper and lowerrail members 108 and 109, is provided. The panel 106 inay'beof metal, glass or other transparentmaterial or insulating board, as
