LATH STRUCTURE Filed Feb. 18, 1929 Patented Aug. 25V, 1931 UNITED STATES "T OFFICE HERBERTI E. WHITE AND WALTER H. EIsHEL, r YoUNGsTwN, OHIO, ASSIGNoRs To v,

TRUscoN STEEL COMPANY, or YoUNesrowi-T, OHIO, AcoRroRAtrfIoN or MICHIGAN LATH sTauoTURE `i A The object ofthe present invention is to provide a simple and effective structure for the purpose that can bey manufactured with expedition and will constitute a complete article of manufacture that is capable of being easily and quickly mounted on studding or other supporting means. 7

A further object is to provide a structure that will require a minimum amount of plaster to cover and constitutes an effective wall.

In the accompanying drawings:

Figure 1 is a face view of a portion of the preferred embodiment of the invention.

Figure 2 is a vertical sectional View on the line 2-2 of Figure 1.

Figure 3 is a longitudinal sectional view on the line 3-.-3 of Figure 1.

Figure 4 is a View of a portion of the back i, of the structure. r

In the embodiment disclosed, a sheet 5 of relatively heavy cardboard orlike fabric is employed. Pressed rearwardly in thissheet are longitudinally disposed rows of elongated v the pockets or ribs of the adjacent rows.

pockets 6,`the pockets of each row being arranged end to end and spaced apart. As a consequence on the rear side of the sheet are produced rows of short ribs 7 that constitute stiffening agents. Moreover the pockets and ribs ofone row are staggered with relation lto T ie portions between the ends of the pockets of each'row are pressed in an opposite direction or forwardly, thus producing on the front face elongated protuberances 8 between the ends of the pockets and in the rear face corresponding depressions 9. Said protuberances have end ywalls forming end walls for the pockets as shown in Figure The end walls of these protuberances 8 and pockets 9 are perforated, preferably at substantially the plane of the front face of the sheet, and through the perforations pass lath rods 10 that thus are held in place by the protuberances and longitudinally bridge the pockets 6, with their rear faces substantially in the plane of the front face of the sheet.

As a consequence of this structure, the lath rods are secured to the sheet by portions of the sheet itself, eliminating 'the necessity of v additional fastening elements, and are spaced from the bottom of the pockets as shown in Figure 2. lIf desired between the pockets 6 and the rodslO the sheet may have rearward depressionsll with rounded tops and substantially straight lower edges 12.` The lowerportions areslitted, thereby providing openings.y

When this structure is applied to studding or .other supports, and the front face plastered, the plaster willbond with the front face of thesheet, surround and thus be held by the lathy rods and will also be keyed to the sheet by passing downwardly behind the same through the slits 12. The pockets of course produce short ribs on the rear side of the backing sheet that reinforce and stiffen the sheet and those ribs of one row bridging the space between those of the adjacent rows, said rows of ribs coacting in this stiffening or reinforcing action. Similarly when the plaster body has been applied and has hardened, that which fills the pockets form From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proy portion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What we claim, is:

ing a backing sheet having a. generally fiat face and provided at intervals with rear wardly recessed key-forming pockets and lath rods bridging said pockets and securedvv (,Onsequently though the finished wall may be vil() 1. A plaster supporting structure, compris- *Y to the backing sheet by passing through the i material of the backing sheet between the pockets, said material supporting the rods in spaced relation to the bottoms of the pockets. V 2. A plaster supporting structure, com-c prising a backing sheet having rows of rearwardly pressed spaced apart pockets and for-y wardly pressed protuberances orrnedA of the material of the backing sheet between the pockets and having end walls that are perforated, and lath rods passing through the perforations'in the end walls of vthe protuberances and bridging the pockets, being supported by theend walls in spaced relation to the bottoms of the pockets.

3. A' plaster supporting structure, oomprising abacking sheet having rows of rearwardly pressed spaced apart elongated pockets and forwardly pressed rotubera-noes formed of the material of the lloackin sheet between the ends of the pockets and avng end walls thatare perforated, and lath rods passing through the perforations in the endwalls of the protuberanees and extending longitudinally of and over'the pockets, in spaced relation to the bottoms thereof.

In testimony, whereof, we aiX our signatures.
