FIRE-PROOF CEILING.
SPECIFICATION forming part of Letters Patent No. 231,351, dated August 17, 1880.
Application filed June 17, 1880. (No model.)
To all whom at may concern:
Be it known that I, JOHN D. OTTIWELL, of the city, county, and State of New York, have invented a new and useful Improvement in Fire-Proof Ceilings, of which the following is a specification.
Figure 1 is a sectional elevation of the improvement. Fig. 2 is a perspective view of a part of the improvement. Fig. 3 is a sectional elevation taken through the line at m, Fig. 1. Fig. 4 is a sectional plan view taken through the line y y, Fig. 3. Fig. 5 is a sectional elevation of a modification of the improvement. Fig. 6 is a perspective view of the same. Fig. 7 is a sectional view taken through the line 2 2, Fig. 5.
Similar letters of reference indicate corresponding parts.
The object of this invention is to prevent the plastering applied to the ceilings at the points where the corrugated arched plates meet the girders from becoming loosened and falling off.
A represents an ordinary iron girder, and B represents an arched plate of corrugated iron supported by and between the girders A. The edge of the corrugated plate B rests upon and fits into a seat in a shoe, 0, which is so formed as to fit into the angle between the web and the base-flange of the girder A. The outer part of the shoe 0 is so formed as to fill up the space between the plate B and the flange of the girder A, as shown in Figs. 1, 2, and 3. The part of the shoe 0 between the plate B and the flange of the girder A has numerous holes, D, formed in it, which holes are made conical and with their larger ends inward, as shown in Fig. 4.
With this construction when the finishing plaster or cement is applied it enters the holes D and sets or hardens, so that the plaster will be dovetailedin place and cannot become loose or fall off. In case the shoe 0 is not used, and the edge of the corrugated plate B rests directly in the angle between the web and basefiange of the girder A, apertures E are formed in the plate B for the plaster used to fill the space between the plate B and the flange of the girder A to pass through. The apertures E are formed by slitting the plate A and pressing back the parts of the plate B at the sides of the said slits to form flaring apertures, as shown in Fig. 7, so that the plaster will be dovetailed to the plate B, and will thus be prevented from getting loose or falling 05.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In a fireproof ceiling, the corrugated iron plate B, having flaring apertures E formed in it, substantially as herein shown and described, whereby the finishing plaster will be dovetailed to the said plate and thus held securely, as set forth.
JOHN D. OTTIWELL.
