,Be it known that 1, WILLIAM GFHURL- BERT, of Niles, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Metal Lathin'g, and I do hereby declare the followin to be a full,

' clear, and exact description of t 'e-inv'ention,

and resistance, and increasedanchoring caaeity, and likewise one which may be readiysecilred in place. r f invention will be hereinafter fully set 01th and particularly pointed out in the claims r Inthe accompanying drawings, Figure 1 is Fig. 2 is a longitudinal sectional view. Fig. 3 1s a cross sectional lie lathing in extensive use has been" formed by striking up loo s, inparallel rows, on one side of sheet meta and in some instances the sheet as a whole has been strengthenedby rid es or corru 'a'tions between and parallel .Wit the severe rows. It has been found, in practice, that the loops themselves areliabl'e to be easily bent because of their inability to stard any considerable weight or pressure, an

proper anchorage forthe plaster.

in some instances have failed to' afford p Further more workmen have found it ;more or. lose all formed on one side'of. the sheetin parallel rows, preferabl separated by ridges or corb dmg hlalcgh loopdlis apchoredinpyi en or pine inwar its 'ongitu '9. sides, which are thereby, for a short distance, made parallel to each other, such sides diverging at their ends. I In thus forming each loop as a narrow arch the maximum of strength is secured, the lathing being capable ofwi'thstanding many times greater pressure than when'flat loops are used. Furthermore, additional anchorage .for the mortar is' thus obtained.-

- In arching the loops irre ular openings are formed in the sheet on t e opposite sides of the loops thereof, such openin widest at the centers of the loops, t us providing clear and 'unobstructedpassages for binding wires. This in itself is a decided advantage, since with the ordinary slits difficult is experienced in securing the lathing in ac'c.

' claim as m invention:-

1. A metal ath consisting of a sheet of metal having a-series of 100 s rojecting being I therefrom, each loop being arc e and having its sides bent toward each other.

2. A metal lath consisting ofa sheet of metal having a series 'of loo s projecting therefrom, each 100 having its sides bent substantially aralle with each other at the center of the 00p.

In testimony whereof, I have signed this ing witnesses.
