Specification of Letters Patent.
Patented Sept. 24, 1907.
Application filed April 8, 1905. Serial N0- 254,560.
To all whom it may concern:
Be it known that I, HERMAN E. VANCE, a citizen oi the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Fireprooi Blinds; and I do hereby declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates more particularly to that class of ilexible or rolling lire resisting curtains which are made up of metallic slats or sections having sheathings or coatings of a material different from that of the 1netallic portion of the slat adapted to resist or retard the lire and heat and especially the conduction and radiation of heat. In some instances the resisting or retardent sheathings may be oi a comparatively brittle or iriable nature in which case it will be important that the impact Vof the slats upon each other' in such I manner as to menace the integrity ot the sheathing be prevented.
The object of the present invention therefore is to provide a construction of slat and curtain in which contact between the sheathing of a slat on another slat is in large measure or wholly prevented, and the invention is embodied in an improved construction for this purpose, the invention not being limited to the precise forms shown.
In the accompanying drawings in which.is illustrated an embodiment ol the inventionwFigure l is a perspective view of a traction oi a curtain showing also how the slats can be connected; Fig. 2 is a sectional view taken longitudinally through a slat, as for example on the line :t-.t Fig. l.
In the several views l designates the metallic portion ot the slat. This metallic portion can be provided at its edges with any suitable hooks or means for connecting it with other slats Or sections. The metallic body portion oi the slat is provided with a series of ribs l1L projecting l'rom one side of the slat and a series of ribs lb projecting from the opposite side thereof. These ribs are shown to be struck up or formed in the sheet metal of the slat but they can be otherwise made. The ribs are also shown to extend transverse the length of the slat, and the series of ribs on one side to alternate with those on the other. Between the ribs on each side of the slat is applied the sheathing or covering 2 which can be of papier mch, asbestos ber or any other preparation or compound adapted to resist iire or retard heat. The fire or heat resisting material 2 is applied to the slat only to such thickness or depth as will permit the edges of the ribs to lie substantially iiush with Or project beyond the face of the resisting material so that when one slat lies on another the contact and pressure ot the former shall be borne by the ribs rather than by the sheathing. The resisting ma terial on the slats is thus protected from fracture or other injury when the curtain is rolled up.
What I claim and desire to secure by Letters Patent is:
l. A flexible fire resistingl curtain embodyingr a plurality ot' hinged metallic slats or sections provided with sheathinjls or coatings of heat resistingmaterial on both sides, said slats or sections having,r projections extending from the body ot' the slat substantially through the outer surface of the coatings o1' sheathings.
2, In a flexible lire resistingcurtain, a Inetallic slat or seetioi provided with means for joining it to other slats and having its body portion provided on both sides with sheathings of heat resistingl material different from that of which the body of the slat is formed and metallic piojections extending from both sides ot the body ot' the slat substantially through the outer' surfaces of the sheathings.
3. In a fire resisting curtain, a metallic Slat provided with means for joining it to other slats and having its btdy portion provided on both sides with sheathing of heatresisting material, and alternating riblike projections bent up in opposite directions out of the body of the slat and projecting' substantially through the surfaces of the sheathings.
4. In a re resisting curtain, a metallic slat provided with means tor joining it to other slats and with projections bent np in opposite directions out of the body of the Slat, and sheathings or coatings of heat resisting material applied to the faces of the Slat, said projections extending substantially through the outer surfaces ot the sheathings.
5. In a flexible lire resisting curtain, a metallic slat provided with means for joining' it to other slats and having its body portion provided on both sides with sheathings ot lient-resisting' material ditl'erent from that of which the body of the slat is formed, and transverse metallic pro joctions extending from both sides of the body of the slat substantially through the outer faces of the sheathings.
(i, ln a flexible fire resisting curtain, a curved metallic slat provided with means for joining it to other slats and having its body portion provided on both sides with sheathin;l of heat-resistingmaterial different from that ot which the body ot' the slat is formed, and metallic projections extending' from both sides of the body of the slat substantially through the outer' faces of the sheathing.
in testimony whereof I allix my signature, in presence of rtwo witnesses.
