FIREPROOF CONSTRUCTION.
SPECIFICATION formingpart of Letters Patent No. 508,501, dated November 14, 1893.
Application filed May 24, 1892.' SerialNo.434,221. (No model.)
.To a/ZZ whom may concern:
Be it known that we, MASON H. CEITTENDEN andFRANK V. EMERY, of the city of Minneapolis, county of Hennepin, and State of Minne- Sota, have jointly invented certain new and useful Improvements in Fireproof Construction for Plastering, of which the following is a speci cation.
4Our invention relates to fire-proof construction for the interior of buildings whereby metallic lathing suitable for coating with plaster maybeconveniently andefticientlysupported.
The object of the invention is to provide sheet metal ceiling-joists having means for attaching metallic lathiug and adapted to be supported by the feet of metallic oor-joists. This object is accomplished by the construction illustrated in the accompanying drawings in Which- Figure 1 shows a sectional elevation of a portion of a floor, the tloor-joists, an arched ceiling, the ceiling-'joists and metallic lathing; and Fig. 2 a transverse section of the ceilingjoists on the line of Fig. 1.
In such drawings l designates the floor; 2 the oor-joists, and 3 the corrugated arched ceiling of sheet-metal of the usual form having its ends supported by the tloor-joists. The space 4 between the arched ceiling and floor may be filled with terracotta or other fireproof material if desired.
The supports for a flat ceiling beneath th oor-joists consist of straight ceiling-joists 5, formed of sheet-metal and preferably made in the following way: Two vertical strips 6 of sheet-metal, having their lower portions bent outward at opposite sides to form flanges 7, are placed together; and around the upward portion of these strips is bent a piece of sheetmetal to form a cap 8 with its lowerportions bent laterally to form flanges 9 above the flanges of the interior strips and the vertical portions 6 and 8 are secured together by rivets 10. A groove or channel 11 is thus made to'intervene the two sets of iianges 7 and 9, for receiving the edges of suitableV lathingsheets 12. The lathing-sheets illustrated have longitudinal grooves 13, and the sheets should also be provided between the grooves with some desired form of tongues, loops or other means for locking the plaster. These are not shown in the drawings as they forni no part of the .present invention.
The ends 14 of the .joists 5, are shaped to t the-angular space between the feet of the lioor-joists and arched ceiling sheet and are seated on the feet of the floor-joists. These ceiling-joists being placed at proper intervals are adapted to receive the edges of the lathing-sheets iu the channels or grooves 11, and to hold them up to a common plane so as to provide a horizontal plasterng surface.
Having described our invention, what we claim is- 1. The combination with iioor-joists, and an arched ceiling supported thereby, of straight ceiling-joists providing longitudinal grooves to receive the metalliclathing and having their ends itt'ing the space between the feet of the tloor-joists and arched ceiling, substantially as set forth. Y
2. v The combination with floor-joists having feet; of ceiling joists supported thereon and providing longitudinal grooves for receiving the edges of metallic lathing sheets, substantially as set forth.
