T at whom it may concern.-

Be it known that I, EDWARD NIDDs, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Lathing System, of which the following is a full, clear, and exact description.

My invention relates to lathing systems, and more particularly to those employing metal. Its principal objects are to provide a convenient lath and to furnish a simple and strong construction.

Reference is to be had to the accompanying drawings, which form a part of this specification, in which like reference characters indicate like parts in the several views.

Figure 1 is a broken top plan view of a lath made in accordance with my invention. Fig. 2 is a side elevation thereof. Fig. 3 illus trates the invention in connection with a ceiling or so-called flat arch. Fig. 4 is a broken front elevation of a vertical construction, as a wall or partition. Fig. 5 is a horizontal sectional detail therethrough, taken on the line 5 5 of Fig. 4; and Figs. 6 and 7 are similar view of other arrangements.

In Figs. 1 and 2 is shown one form of my improved lath, which is preferably stamped from sheet metal 10 and is of a length and width most convenient for the uses to which it is to be put. The former dimension is considerably greater, the laths thus being in comparatively long strips. Each lath is divided into a lurality of sections 11, in which are formed icy-openings 12 to receive and lock in place the plaster which is applied to the system in which the laths are employed.

These openings are preferably cross-shaped, they having intersecting arms 18 13, which are shown as situated at right angles to one another. The key-openings are arranged in series or rows both longitudinally and transversely of the lath, and considering the transverse series the arms of each project between the corresponding arms of adjacent series, the openings being in staggered relation to one another. This disposition of key-openings gives the maximum area with the minimum reduction of strength of lath and furnishes a particularly effective interlocking of the plaster. Extending across each of the sections 11 are longitudlnal corrugations 14, which serve to strengthen the lath against distortion. These corrugations are shown as four in number, there being one at each edge, and in these outside corrugations are formed slits 14", which furnish between them su porting-tongues 14 etween the sections 11 are s aces 15, across which extend transverse in ex-marks 16, here shown as consisting of small corrugations.) These furnish a guide by which the lath may be bent by the user to adapt it to various applications. Seven of these index-marks are illustrated in each group, and from opposite sides of those at each side of the center extend locking-tongues 17, which may be bent from the plane of the surrounding metal to engage supporting elements.

In the ceiling system (illustrated inFig. 3 of the drawings) beams 18 are provided having flanges 19, which support intermediate flat bars 20. The laths are bent upon the index-marks to furnish transverse depressions which surround these bars. In the present instance this bending is upon the center mark, the relation between the elements being'such that this causes the sections 11 to lie below the plane of the bottom flanges of the beams, and the laths being bent until the adjacent edges meet beneath the bars they furnish an uninterrupted surface to receive the plaster. It should be noted that the bars not only support the laths, but that the laths in turn malntain said bars against lateral displacement. The system thus eliminates all auxiliary securing means either for the laths or bars. Though I have shown only a flat ceiling construction, it will be obvious that the invention is equally applicable to segmental arches. In fact, the arrangements in which it may be used are limited only to the capabilities of bending the bars and conforming the lathing.

To furnish vertical surfaces to receive the plaster, the laths may be similarly bent, this being done upon lines which give the desired air-space. Then the laths may be either fixed in place by nails driven through the bottom of the depressions or they may surround furring strips or bars 21. To these they may be locked or clenched by alternately bendin the tongues 17 over the outer edges of the bars and into the spaces furnished by forcing back the opposite tongues,-

as is shown in Fig. 5.- Here the outer series of said tongues is used, since the bars are of considerable width, or, as is shown in Fig. 6, the inner tongues may be bent over narrower bars 22 and similarly inserted through the opposite spaces. In Fig. 7 still another arrangement is illustrated, the outer tongues being alternately turned across a narrow bar 23. It will be clear that if a still greater airspace is desired than would be furnished by the depressions formed from single spaces these depressions may be made to include the intermediate sections 11, the bending being done upon the index-marks at each side thereof. In addition to the support furnished by the nailing of the laths or by engagement of their locking-tongues they may be further maintained in the proper relation to one another by pressing outwardly in opposite directions the tongues 14* at the lower edge of each lath, so that they will straddle the upper edge of those below them, thus positively preventing displacement by one another.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A lathing system, comprising bars, and laths having portions surrounding and extending beyond the bars at one edge, and having interlocking engagement with similar portions of the laths.

2. A lathing system comprising bars, and laths having portions cooperating with the bars, said laths .being provided with lookingtongues.

3. A lathing system comprising bars, and laths having portions cooperating with the bars, said laths being provided with tongues extending over the bars.

4. A lathing system, comprising a series of laths each provided with cross-shaped keyopenings, the arms of each opening of one series having portions extending between those of an adjacent series, transverse corrugations extending between the key-o enings, longitudinal corrugations extending etween the series of key-openings, transverse indexmarks extending between the sets of openings, and a series of tongues extending transversely across the laths between the indexmarks, said laths having portions adapted to surround and extend beyond the edges of a supporting-bar and interlocking with each other.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. I

EDWARD NIDDS.
