CEILING 0R WALL CONSTRUCTION FOR FIREPROOFBUILDINGS.

SPECIFICATION forming part of Letters Patent No. 728,919, dated May 26, 1903. Application filed October 4. 1902. Serial No 125,864. (No model.)

To a whom it may concern:

Be it known that 1, WILLIAM HORN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ceiling or WVall Constructions for Fireproof Buildings, of which the following is a specification.

My invention relates, generally speaking, to an improvement in the construction of fireproof buildings wherein the skeleton or supporting elements are formed of iron girders or beams usually employed in 'c'ommercial structural forms; and my invention relates more particularly to an improved construction of ceilings and partition-walls, the novel feature of the invention residing in an im proved form ofclip for uniting theilltersecting beams and gi'i'ders-constituting the suppfiti'trg'structure for the lathin'g and plaster.

The object of my invention is to provide a clip for this purpose which shall combine superior simplicity and cost of manufacture with increased strength and rigidity, a secondary object of the invention being to provide a clip which shall be more economical of space required therefor than other devices for the same purpose with which I am acquainted.

For purposes of convenience I have illustrated my invention in a preferred embodiment thereof in connection with aceiling construction.

In the accompanying drawings, Figure 1 is a vertical transverse section through one of the main ceiling girders or beams, the underlying ceiling-iron and my improved clip for uniting the same to the girder being shown in side elevation. Fig. 2 is a similar view of the same parts as they appear in a plane at right angles to the plane of the parts in Fig. 1. Fig. 3 is a perspective detail of my improved clip, and Fig. 4 is a perspective view of the parts shown by and occupying the relative positions illustrated in Figs. 1 and 2.

Referring to the drawings, 5 designates the usual transverse girder or beam of a ceiling or floor construction, here shown in the form of an I-beam, and 6 designates one of a series of transversely-extendingceiling-ironsadapted to have attached thereto some form of metal lathing. This iron, as herein shown,

is in the form of a channel-beam having its web disposed in a vertical plane.

In making my improved clip for uniting the elements 5 and 6 I take a plain flat piece 7 of strap iron or steel, preferably of rectangular form, and cut or punch therethrough at separated points apertures 8 of a size and form to slidingly but comparatively snugly fit the cei1ing-iron 6 when the latter is passed through said apertures. I then bend up the two end portions of the strip along lines coincident with the innerorbase margins of the apertures 8, thereby forming vertical supporting members 9, and finally I bend over inwardly to ward each other the upper ends of the upstanding members 9 to form end flanges 10, adapted to overlie and rest upon the lowermost head of the I-beam 5.

The manner in which the parts are assembled and their relative location is obvious from the illustration and need not be further described. I will therefore briefly mention a few of the advantages which I believe my invention possesses over other known forms of clips. In the first place,'it will be observed that the clip afiords a seat or support for the ceiling-iron of an extent equal to the full width of the head of the ceiling-beam. In the second place, the vertical supporting members 9 of the clip are rigidly tied together at their lower ends. In the third place, my invention enables the uppersurface of the ceiling-iron to be brought into direct contact with the under surface of the ceiling beam or girder, thereby affording an economy in the space required for the ceiling structure as compared with constructions now known and used, wherein a part or element of the clip lies between the adjacent surfaces of the beams 5 and 6. In the fourth place, my invention, being of extremely-simple construction and requiring butlittle cutting and bending of the blank from which it is shaped up, is capable of being produced at areduced cost as compared with other clips for the same purpose with which I am acquainted. Finally, the clip presents no obstruction to the plaster.

It will be obvious that my improved clip is capable of use with other forms of intersecting beams and irons, such forms necessitating only obvious modifications of the apertures 8 and of the flanges 10 to make them conform to the particular shapes of the beams and irons used. The particular forms herein shown are therefore illustrative merely. It is also obvious that my invention may be employed with equal advantage in the construction of fireproof partition-walls other than floors and ceilings.

1. The combination with the main girder and a transverse beam intersecting the plane of said girder, of a clip for uniting said elements in surface contact, said clip comprising a -strip of strap metal having a base equal in length to the width of the adjacent head or flange of the girder and having its end portions bent at right angles to the base and apertured to receive the transverse beam, and further having the free extremities of said end portions bent inwardly to embrace the margin of the head of the girder, substantially as described.

2. The combination with the main girder and atransverse beam intersecting the plane of said girder, of a clip for uniting said elements in surface contact, said clip comprising a strip of strap metal having a flat base forming a seat for the beam and having its end portions bent at right angles to the base and apertured to receive the beam, the lower margins of said apertures being substantially coincident with the plane of the base, and
