Specification of Letters Patent.
Application filed September 20, 1907. Serial No. 393,786.
Patented Sept. 22, 1908.
My invention relates to doors of that class known as fire doors and designed .to effectu ally resist the action of fire. It is common in constructing doorsof this character to employ a framework of wood which is covered with sheet metal and it is desirable that the 'edges of the sheet metal be secured to the frame in as neat a manner as possible and if the edges can be entirely concealed, so much.
the better.
To provide a fire door having the edges of the sheet metal covering entirely concealed, I construct my im roved fire door in two parts adapted to be rou ht face to face with each other, the abutting aces being provided with interlocking members adapted to enga c with each other to lock the sections firm y together. B virtue of this construction, the edges of t e sheet metal covering are concealed within the body of the door and by reason of this fact it is not necessary to trim these edges to a predetermined size as is the. case where the ed es of the metal coverlng lie upon the exterior of the door.
Further objects and advantages of the invention will be set forth in the detailed description which now follows.
In the accompanyin drawing: Figure 1 is a view in elevation i ustrating the inner face of that ortion of the door illustrated at the lower si e of Fig. 3, Fig. 2 is a horizontal section throu h the two halves of the door before said ha ves are forced together, Fig. 3
is an enlarged sectional view illustrating the interlockin members in the position they occupy be ore the sections are forced together, Fig. 4 is a like view illustrating the parts in the position they occupy after the parts have been forced together, said sections being taken on the line of one of the brace rods hereinafter described, Fig. 5 is a detail sectional view illustrating a method of bending the inner edge of the metal covering around one of the clamping members, Fig. 6 is alike view illustrating the method of bending the inner edge of the sheet metal covering around the other of said clamping members,
Fig 7 is a detail perspective View of one of the brace rods hereinafter described, and, Fig. 8 is a view of the interlocking members after the "have been forced into engagement with each other. Like numerals designate corresponding parts in all of the figures of the drawing.
Referring to the drawing, the numerals 5 and 6 designate a pair of rectangular and preferably wooden frames, though it is to be understood that frames constructed of other material than wood, may be here utilized if desired. The frame 6 has a sub-frame 7 secured thereto, said sub-frame extending entirely around the frame 6. The frames are covered with sheet metal coverings 8 and 9, these sheet metal coverings being stamped out to the form of the door and their inner edges being secured by screws 10 to the frames 5 and 6. These screws also secure the interlocking members to the frames, said interlocking members bein formed by angle bars which comprise the ho y portions 1 1 and 12 through which the screws 10 pass and the inwardly directed flanges 13 and 14 which are adapted to engage with each other as will be heremafter described.
When the two sections of the door are forced together by a power ress, the subframe 7 is forced up against t e frame 5 and the inwardly directed flanges 13 and 14 are forced into on agement with each other as is illustrated in Fi ing the two portions of the door together and leaving but a faint seam around the outer edge of the door, the inner edges of the sheet metal coverings 8 and 9 being concealed within the door. Since these edges are thus concealed within the door, it follows that they may be cut to fit very roughly.
When the sheet metal coverings are pressed out into the form of a door, panels 15 are pressed into them. The provision of the sub-frame 7 spacesthe two halves of the door from each other in such manner as to provide a space for the reception of the interlocking members after the parts have been brought together. This results in spacing the two metal coverings from each other and it is desirable to brace the door internally so that blows upon the exterior of the door will not unduly dent and disfigure it. To accomplish this, brace bars such as are shown in.
Fig. 7 are rovided. These brace bars are slit longitu inally as at 16 and one side of the bar is bent upwardly as at 17 and the other side is bent downwardly at 18.
g. 8, thereby effectually lockbetween the rai The outer ends of the bar are provided with hooks 19 adapted to engage over the flanges 14 upon opposite sides of the door and the flanges 13 are cut out as at 20 (see Fig. 7) for the reception of the ends of these brace bars, then when the two halves of the door are forced together, the ends of' the brace bars are pressed firmly into engagement with the flanges 14 (see Fig. 4). Since these ends lie in the cut out portion of the flanges 13, the brace bars are prevented from slipping sidewise and the engagement of the hooked ends 19 with the flanges 14, of course, prevent endwise movement of the bars. When these bars are arranged between opposed panels, the portion 17 rests against the lndented face of one panel and the portion 18 rests against and braces the indented portion of the opposed panel. These bars may be arranged only between the panels or only between the rail portions 21 of the door, or they .may be arranged both-between the rail portions and the panel portions.
If desired, the inner ends of the sheet metal coverings may be bent over the interlocking v members as illustrated at 22 and 23 in Figs. 5 and 6. It will of course be understood that where the brace bars are arranged between the rail portions of the doors instead of between the panel portions, the members 17 and 18 of the brace bars will have to be bent farther apart than is the case when the bars lie between the anels, for there is more space ortions of the doors, than between the panel ortions.
It may be foun desirableto indent the panel portions of the doors so deeply that when the two halves of the door are forced together, the anel portions will rest against each other. lhis will obviate the necessity of bracin them, and in this case the brace bars wou (1 only be used between the rail portions of the doors.
The body portions 11 and 12 of the interlocking members are overlapped at the corners of the door and secured together by screws 25. It will therefore be seen that the interior skeleton frame formed by these angle bars and the brace bars is complete in itself, so that even if all of the wood-work be burned out of the interior of the door, the skeleton frame will still support the door.
A still further important oint of novelty and advantage, resides in t e fact that the inner edges of the metal covering pass be-- neath the body portions of the interlockinlg members and the screws 10 passing throug these members and through the metal covering, tieathese parts together and make a connected metal structure that will stand up of itself, even though the core be destroyed. It will also be seen that by virtue of this construction, a metal barrier consistingiof the interlocking members lies at the base of the seam between the parts to effecusual fireproof shutters em loyed.
hi h. %t is to be understood that the term door where used throughout this specification and the claims appended thereto, is to be construed in a broad sense. A closure constructed in accordance with the invention may be used to close a doorway, or to close a window after the manner of the I wish it to be clearly understoo therefore that my invention is not limited to the use of closing doorways alone but that closures constructed in accordance therewith may be used in the place of, or as, shutters.
From the foregoing description, it will be seen that the present invention comprises means for constructing a fire resisting door that will be very neat in appearance and which will be effectually braced and strengthened throughout, but while the elements shown and. described are well adaptedto serve the purposes for which they are intended, it 1s to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made with- .in the scope of the appended claims.
What I claim is:
1. A closure of the character described made in sections and covered with sheet metal, said sections being secured face to face with each other, the edges of the sheet metal cover lying upon the inner face of each of said sections and interlocking members carried by the inner face of each of said sections and engaged with each other, said members being-adapted to automatically engage with each other to lock the sections together when said sections are forced towards each other.
