Description
UNITED sTkTns PATENT oTTIcE.
JOHN B. CORNELL, OF NEW' YORK, N. Y.
CONTINUOUS SHEET-METAL LATHING-SURFACE.-
Speccation forming part of Letters Patent No. 14,854, dated May 13, 1856; Ressued August 3, 1858, No. 576.
Lath-Surface to be Used in the Formationh of Fireproof and Burglar-Proof Partitions Supported by Wooden Studs; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, Figure l being a side view of several connected sections ofmy improved metallic lath-surface, and Fig. 2 a transverse section in the line a a of Fig. l.
My improved continuous lath-surface, is composed of narrow sections b, b, of sheet metal, which are swaged into the shape and locked together in the manner represented in the drawings-to wit, one edge of each strip of sheet-metal is bent into a prismatic shape, and the opposite edge (Z, of said strip is turned upward and inward into a shape corresponding with the inner surface e, of the prismatic shape of the first mentioned edge of said strip. Strips thus shaped it will be perceived, can be locked together in the manner represented in Fig. 2, by placing the edge ,'of one strip within the hollow prismatic shaped edge of another strip,
so as to form a continuous covering to be nailed upon studs or girders for the reception of a coating of plaster or cement. The aforesaid shape of the edges of the strips or sections, is such as to form a dove-tail shaped groove in the face of each strip, for the reception and retention of the mortar. Vhen a series of strips or sections, have been locked together and nailed to studs or girders, it will be perceived that the inner strips of the series cannot be removed without firstbreaking off their edges by force, and thereby necessarily making a good deal of noise, which would render the operation a dangerous one for burglars in a crowded city.
What- I claim as my invention and desire to secure by Letters Patent, is-
A continuous sheet-metal lath-surface formed of united strips or sections of the shape substantially as herein set forth.
The above specification of my improved continuous sheet-metal lath-covering, for fire-proof and burglar-proof partitions, signed and witnessed this 7 th day of April,
JOHN B. CORNELL. Witnesses:
JOHN M. DoDD, THos. CRocImn [FIRST PRINTED 1912.]
