.To a/ZZ whom it may concern.-
` Be it known that we, MASON H. CRITTENDEN and FRANK V. EMERY, citizens of the United States, residing at the city of Minneapolis, in the county of Hennepin and State of Minnesota, have jointly invented certain new and useful Improvements in Fireproof Construction for Plastering, of which the following is level surface for the ceiling and enables metal iioor and ceiling and their supports constructed in substantial accordance with our improvements; Fig. 2, an enlarged transverse section of the ceiling-joists and metallic lathing on the line x-x of Fig. l; Fig. 3, a side view, on the same scale as Fig. 2, ot a portion of the ceiling-joist and metalliclathing; Fig. 4, a side view ot one of the ends o f a ceiling-joist; and Fig. 5, a transverse section of the same on the line y-y of Fig. 4.
In such drawings l designates the floor; 2 the iioor-joists of metal and I-shaped; and 3 a plate of corrugated sheet-metal in arched form with itsv ends supported at the junctures of the feet4 and webs'of the floor-joists. The space 5 intervening the iioor and the arched ceiling 3 may be wholly or partially iilled with re-proof material, or left vacant, as desired. v
To enable metallic lathing to be attached in horizontal position beneath the floor-joists, we provide the ceiling-joists 6 which are preferablyconstructed of twostrips of sheet-iron bent to channel-shape and secured together at proper intervals by rivets 7. The ends of the ceiling-joists thus constructed are made t0 taper at a proper inclination, as indicated at 8, to conform substantially to the shape of the arched ceiling; and. in the ends of the joists are provided slots 9 of proper shape to tit the feet or Iianges of the Hoor-joists. The metal at the upper edges of these slots is bent outward at opposite sides to form iianges 10 for the purpose of providing comparatively wide bases for seating the ceiling-joists on the feet of the hoor-joists. Ceiling joists thus conmembers forming the joists to permit nails to be driven between them at intervals and force the members slightly apart, while they serve to firmly clampV the nails. the metal of the joists is indicated in Fig. 2, in somewhat exaggerated form, to plainly illustrate it.
The use of floor-joists and metallic lathing of the character and in the manner described is found, in practice, to overcome the diiiiculty usually experienced in providing a iiat surface for plastering a ceiling where metal oor-joists and tire-proof arched ceilings are used in building construction.
It is not intended herein to claim broadly the character of ceiling-joists, or other b'uilding member described, for that feature is reserved to be claimed in another application, SerialNo. 468,833, tiled April 3, 1893, concurrently pending.
Having described our invention, what we claim is l. The combination with floor-j oists, of ceiling-joists formed of channel-shaped sheet- This spreading of y tially as set forth.
2. The combination with loor-joists having feet; of ceiling joists, supported by said feet,
` and composed of hanged sheet-metal parts having plane surface backs secured together back to back and having sufficient elasticity to receive and hold nails driven in the joints between them; and metallic lathing attached by nails driven in such joints, substantially as set forth.
3. The combination with ioor-joists having feet; of ceiling-joists formed of hanged sheetmetal parts having plane surface backs secured together back to back and having their ends slotted to receive the floor-joist feet; and metallic lathing attached by nails driven in the joints between the parts of the ceilingjoists, substantially as set forth.
4. The combination with floor-joists having feet; of ceiling joists formed of hanged sheetmetal parts secured together back to back and having their ends slotted to receive the floor-juist feet and having the upper edges of such slots flanged, for the purpose set forth.
