mosses.
To (ZZZ whom it may concern:
Be it known that l, lVILLIAM id. limiUEn, a citizen of the United States, residing at Dubuque, in the county of Dubuque and State of Iowa, have invented certain new and useful improvements in Metal Ceilings, of whichthe following is a specification. My invention relates to metal ceiling. The invention has special reference to detailed formation of the sheets from which ceilings are made, looking to betterment and reduction in cost of production and use.
lily invention consists in the formation of a metal blank into a ceiling section provided with edges for overlapping, specially formed for matching adjacent sections and provided with rosetted portions adapted not only to receive nails and house the heads thereof to present a neat appearance but particularly topresent a considerable number of places for nailing but nonpertorate that nails need not be applied at each rosette.
The salient feature of my invention lies in the formation ot' the rosettes, via, the forming a seat for the nail heads and the thinning of the metal in the scat depression that a nail will readily penetrate it with a slight tap of a hammer.
Referring to the drawings: .Figure 1 is a plan view of a metal sheet. .Fig. 2 is a sectional view, sections at the joining point and the attachment strip showme the nail applied to effect the tastening.
Fig. 3 is a section (it overlying rosettes showing the thinning of the metal at the nail seat point. a
I am aware that metal ceiling is disclosed in the patented art and also is in practical use employing rosettes at and the centers of which perforations are made but in the use of such ceiling sections it is necessary, for the sake of appearance at least, that nails be driven at each rosette, and it is to avoid this neccssit that l have formed my rosettes nonpcrit orate. Also am aware that ceiling sections have been used em 'iloying nonper torate rosettes of normal thickness ot the metal, within and through which. nails are to be driven, but it is very diiticult tor a workman, particularly in the awkward position in which he is required to wort: in applying the sheathing, to drive the nails through the thick metal. Besides there is a considerable loss of time.
Referring to the drawings:

way, to indicate the ceiling members of a building forming the foundation for attachment of the ceiling sections. A is a ceiling section, B is a margin or edge of the ceilmg section designed to'overlie and match similar edges of similar sections. 2 are ribs serviceable to stiffen edge members B. 3 are rosettes (best shown in Fig. 3), the same being formed by stamping to gradually thin the metal. from the interior periphery of the rosette to its center-the center portion being reduced to substantially the thickness of ordinary one ply paper,so that it may be readily penetrated with the ordinary ceiling nail. v r 5 is a ceiling nail, the head .6 of which may be specially formed with'a double convex head as shown, that a'rounded face may be presented to conform with the general are of the rosette that the rosette as a whole, including the nail head, shall present a rounded appearance and that the base ofand purpose of my invention, which is, the
forming of ceiling" sheets with nail entrance points or seats thinned to substantially the thickness of one ply paper and a proper housing of the seat to give direction to the nail while it is driven and to prevent the lateral breaking away of the metal as the nail is driven.
What I claim is:
1. As a new and improved article of manufacture, a metallic ceiling section comprising a sheet of metal having a rosette protruding therefrom, said rosette being dished at its attaching point to afford a centering point for the attaching nail, and the metal at said point being thinned to permit the piercing thereof by the driving force of a nail.
2. in a cciling'structure, a metallic ceiling section comprising a sheet of metal having a rosette protruding therefrom, said rosette being dished at its attaching point to atlord a centcring'point for the attaching the driving force of a nail, abacking against which the ceiling section abuts and away from which the rosette protrudes,and a nail driven through the thinned section of the .rosette and into the backing.
3. In a ceiling structure, a metallic ceile ing section comprising a sheet of metal having a rosette protruding therefrom, said rosette being dished at its attaching .point to afford a centering point' for the attaching nail, and the metal at said point being thinned to permit the piercing thereof by the driving force of a nail, a backing against which the ceiling section abuts and away from which the rosette protrudes, and a nail driven through the thinned section of the rosette and into the backing, the nail having a 'head configured to close the recessed por
