No. 640,809. Patented Jan. 9, I900. J. W. RAPP.
CEILING CONSTRUCTION.
(Application filed Mar. 10, 1899.)
(No Model.)
WITNESS ES I UNITED STATES PATENT OFFICE.
JOHN W. RAPP, OF NEW YORK, N. Y.
CEILING CONSTRUCTION.
SPECIFICATION forming part of Letters Patent No. 640,809, dated January 9', 1900.
Application filed March 10, 1 8 9 9.
To all whom. it may concern:
Be it known that 1, JOHN W. RAPP, a citizen of the United States of America, residing at New York, in the borough of Manhattan, county and State of New York, have invented certain new and useful Improvements in Ceiling Construction, of which the following is a specification.
My invention relates to a construction for ceilings.
I will describe a construction embodying my invention and then point out the novel. features in the claims.
In the drawings, Figure 1 is a vertical sectional View of a ceiling construction embodying my invention. Fig. 2 is a perspective view of a strip of ceiling-lath employed in my invention. Fig. 3 is a view similar to Fig. 1 and showing a modified construction. Fig. 4 is a detail transverse sectional view showing how adjacent strips are connected. This figure is drawn to a larger scale than Figs 1, 2, and 3.
Similar letters of reference designate corresponding parts in the several figures.
A A represent I-beams which are ordinarily used in the construction of buildings to support the floors thereof. These beams may be supported in any desired manner. Intermediate the I-beams a floor-filling B is placed. This filling may be supported in any desired manneras, for example, by a metallic arch B. I have shown the metallic arch as being made of corrugated metal, which may be in strips of suitable size. These strips are supported by their ends resting on the flanges a of the I-beams. If desired, the metal strips :IEI GBd not be corrugated, but plain, as shown in G represents a perforated metal sheet commonly known as metal lath. This lath is adapted to support the ceiling and is held suspended from the I-bearns preferably by means of the metallic arch. In the drawings I have shown its end portions bent in such a manner that they will be engaged by the metal arch. The end portions of the lath are bent at c, c, and 0 The ends of the metal arch fit in the bonds 0, and the metal intermediate the bonds 0 and c rests on the flange a of the I-beam. The metal intermediate the bends c and 0 Serial No. 708,525. (No model.)
extends at an acute angle to the main portion of the lath and is adapted, in connection with the same part on a lath in an adjacent arch, to hold a plaster block E beneath the flange of the I-beam, as shown in Fig. 1. The side edges of each strip 0 are provided with bends 0 The purpose of these bends is to enable each sheet to be connected with its adjacent sheet, as shown in Fig. 4. The lath is put in position and the metal arch then placed between the I-beams, with its ends fitting in the bends c at the ends of the lath. As the filling is put upon the metal arch its weight tends to flatten the metal arch and cause its ends to spread. As the ends spread, the ends of the lath are spread, causing the bond 0 to fit the edges of the flanges of the I-beams, and thus locks the lath on the flanges of the I- beams. The ceiling material is then applied to the lath in the usual manner.
In Fig. 3 I have shown the lath as provided with only a single bend c, which is for the purpose of receiving the ends of the metal arch to lock the lath on the flanges of the I- beam.
What I claim as my invention is- 1. The combination with I- beams of a metal arch between said beams, and metal lath supported on the flanges of said I-beams, said metal lath being provided with bends at its end portions into which the ends of the metal arch project, substantially as described.
2. The combination with I-beams, of a metal arch between said beams, metal lath supported from said I-beams and bends c, c, 0 provided in the ends of said lath, substantially as described.
3. The combination with I-beams of a metal arch between said beams, metal-lath sheets supported from said I-beams by the metal arch, each of said sheets being provided with a bend at its side edges which bends engage with corresponding bends on adjacent sheets of metal lath.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JOHN W. RAPP.
