J.`B.00RNELL. FIREPROOF CEILING.
Patented Mar. 23, 1858,.
UNITED STATES PATENT OFFICE.
JOHN B. CORNELL, OF NEW YORK, N. Y.'
IMPROVEMENT IN FIRE-PROOF oralLlNcs.v
Specification forming part of Letters Patent No. 19,682, dated March 23, 1858.
ing a part of this specification.
Figure 1 isasect-ional representation of said improved ceiling,r and ofv one of the beams to which it. is suspended,and Fig. 2 is atop view of several combined metallic lath-sections prepared with a view to their being suspended to wooden beams to form the essential portion of my said improved fire-proof ceiling.
Similar letters indicate like parts in both drawings.
-In constructing' my improved fire-proof ceiling I first take sheet-metal lath-scctions b, of
anysuitable shape for retaining coatings of plaster applied to their surfaces, and suspend the same to the beams overhead by means of screws d d, or any other suitable means,in such positions as to form a uniform lath-surface at a short distance below the lower edges ot said beams. 1 The space between the metallic lath-sections and the under edges of the beams A which sustain them must be'of such a depth that a .coating of gypsum or some otherlsuitable non-oonducting composition may be placed upon said sections and have a depth which will be amply sufficient to protect the wood-work above the same from bcing ignited by means of any degree of heat that may be exerted thereupon from below. The coa-ting or coatings of lceilingplaster may be combined with the under side of the said suspended lath-sections in v4any well-known and usual manner;
The accompanying drawings represent a continuous metallic-lath surface composed of corrugated sections b b, combined with each other by means of. transverse met-allie strips ,I
c o and a suitable number of rivets e e. To facilitate the giving of a uniformly-horizontal position to the said metallic-lath surface when4 suspended and ready for use, non-conducting thimbles ff may bei nserted between the lath sections b b and the lower edges of the sus? i taining-beams, which thimbles may embrace the screws or bolts that suspend the said sections. That I claim asmy invention, and' desire to secure. by Letters Patent, is
My improved method of constructing irc proof ceilings beneath Wooden beams-viz., by
.suspending combined metallic lat-h-sections
