Taall wltomt't may concern:
Be it known that I, EnwAno H. MoCLoUD, 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 Improvement in Fire-Resisting Doors, of which the following is a specification.
The object of this invention is to provide a simple and economical form of door of the sliding type chiefly of metal and especially adapted for use in resisting fire. In such doors it is important to provide against buckling and the formation of openings through which, flame or sparks can pass when the door is subjected to the action of fire and it is likewise important to prevent the danger of ignition of articles at one side of the door by the radiationof heat through the door from the opposite side. My invention therefore is directed chiefly to improvements in details of construction whereby safety in the respects stated is promoted.
The invention is embodied in the construction shown in the accompanying drawings, set forth in the following description and finally claimed.
In the drawings-- Figure 1 is a front view of a sliding door according to the invention.
Fig. 2 is a horizontal section on the line II-II Fig. 1.
Fig. 3 is a fractional vertical section on a larger scale on the line III-III Fig. 1 to better illustrate details.
Fig. 4 is a fractional horizontal section on the line II-II Fig. 1 on a larger scale to better illustrate details.
The frame for the door body as shown includes a metallic angle bar 5 notched, bent and welded at lines 5 and 5 on one of the webs of the bar to form the upper corners, the lower portion of the frame being formed by a plain strip 6 riveted to and connecting the lower ends of the vertical sides of the frame portion formed by the angle bar 5. Secured vertically within the frame is a series of wide plates or strips 7 of deeply corrugated sheet metal and secured opposite the vertical strips is a series of horizontally extending wide strips 8 of similarly corrugated sheet metal. These wide strips of sheet metal at each face of the door are so formed, out and placed as to leave outwardly turned edges and the spaces between blocks 11 and 12 placed opposite each other in the narrower strips and connected bv rivets 13 or other suitable fastenin means. One or more of the holes throng which said rivets pass should: be slightly elongated to allow for difference in expansion. The end strips 7 have angularly extending margins to fit against the inner side of the vertical portions of the frame and they are secured to said frame by rivets 1% passed through a slot in said margins such as indicated at 15. Normally the vertically standing corrugated strips rest on the lower frame member 6 and do not extend the full height of the frame so that when the door is subjected to the action of fire the strips can expand upward. The uppermost and lowermost of the horizontally extendin corrugated strips 8 likewise are provi ed with angularly extending margins as at 8 by means of which they can be fitted to the top and bottom members of the frame. Likewise also these strips are secured by rivets as at 16 passed through slots as at 17. These horizontally extending corrugated strips are shown (see Fig. 4) as being of less length than the distance between the sides of the frame 5 so as to provide room for the lengthwise expansion of said strips when subjected to the action of fire. Fusible washers are placed under a head of each of the rivets l4 and 16 so that the parts shall be free to expand when subjected to the heat of fire. The vertical spaces between the ends of the horizontal strips 8 and 10 and the frame 5 are covered by an angle strip 18 secured in position by the rivets 1% that also secure the angular margins 7 of the end strips 7. The space between the upper ends of the strips 7 and the horizontal web of theframe portion 5 is additionally covered by the vertical web of the angle bar 5.
I have shown the structure thus described as used to form an automatically released sliding fire door of well known arrangement, In the instance shown the door is provided with hangers 20 carrying rollers 21 to run on an inclined track 22. The lower portion of the door is furnished with a bearing strip 23 engaged by a roller 2+1 secured on the door jamb 25 to hold the door toward the door opening. Keepers 26 and 27 of the door jamlis are shown to aid in holding the two edges of the door closed when in closing sition.
What I claim is:
l. A door body comprising in combination a frame and panels or faces in said frame formed of corrugated stri s, the corrugations of the strips of one face of the door extending at angles to those of the other face of the door, the strips of one face of the door being of less length than the distance between the frame members, and a strip secured to the frame independently of the corrugated strips closing the gap between the ends of said corrugated strips and the frame.
2. A door body comprising in combination a frame, a plurality of relatively wide and narrow parallelly arranged strips forming a panel or face thereof the wide strips being freely movable and alternating with and engaged at their margins by the narrow strips and means securing the narrow strips and thereby holding the wide strips normally in place.
A door body comprising in combination a frame, a plurality of wide and narrow corrugated strips forming each of the fitCGS thereof, the wide strips being freely movable and alternating with and engaged by the narrow strips, the strips of one face of the door extending at angles to those of the other and means securing the narrow strips at the opposite faces together and thereby holding the Wide strips normally in place.
4; A. door body including, in combination, a frame and a panel in said frame formed of a plurality of corrugated stri )S of less length than the distance between t e frame mem bers. said strips being freely movable when subjected to expansion by heat, a separate strip on the frame member extending crosswise of the ends of said corrugated strips to close the gap between the ends of the latter and the frame and thermally controlled means securing said gap-closing strip to the frame member.
