SPECIFICATION forming part of Letters Patent No. 582,368, dated May 11, 1897.
Application iilecl .Tune l, 1896. Serial No. 593,682. (No model.)
To all whom t may concern:
Be it known that I, ROBERT OTTERsoN, a citizen of the United States, and a resident of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Metallic Lathing, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to that class of lathin g made of corrugated sheet metal and having apertures made by striking tongues from the sheet metal, which tongues act as guards to prevent too large an amount of mortar or plaster passing through the apertures and as guides to force the mortar against the receding side of the corrugations of the metallic sheet. The sheet is preferably of steel, and the angle corrugations extend lengthwise of the sheets, and the face convolution is oval in cross-section, by which means I attain and insure an increased rigidity in the lathing.
My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.
lReferring to the drawings, Figure I is a view in front elevation of the lathing. Fig. II shows a rear elevation of the lathing, to which plaster has been applied,and illustrates the keying of the plaster between the tongues. Fig. III illustrates a section taken on line III III, Fig. II. Fig. IVillustrates a section taken on line IV IV, Fig. II.
In the drawings, 1 designates the metallic lathing-sheet, which I corrugate in a suitable machine, and in which apertures 2 are formed by the employment of suitable dies in a machine. The apertures 2 are formed by cutting out tongues 3 and '4. from the opposing forward convolutions of the sheet.
The tongues are cut from apoint at the base of beads 5, that form the crowns of the corrugations, and downward to the base of the forward convolutions, thus causing the tongues when 4pressed back to be approximately on a line with the base of the forward convolutions. In this position the tongues are out of the way for the passage of plaster through the apertures 2 and form guides to direct the plaster in passing through the apertures toward the opposing convolutions ofthe sheet, and consequently toward the tongue cut from the opposing convolution. In this way' the plaster' is pressed from each directionv through the apertures, and the key A, produced by the plaster, forms a lock much more secure and efficient than in the ordinary forms of metallic lathing. The tongues 3 and 4. also act as guards against an excess of plaster being pressed through the apertures.
The lower or depressed convolution is an obtuse angle, and the upper or face convolution the oval bead, running lengthwise of the same, on each side of Whichis' a flat shoulder or offset (i. This oval bead serves to stiffen the eorrugation and make the sheet more rigid. It also presents a rounding surface, over which the trowel moves in plastering the sheet, lessening or removing the danger of the plaster cutting from the trowel in applying same. The square shoulder or offset 6 has these objects, namely: It presents a level surface on which the cutting-die strikes, making it easier to cut and less apt to pull or stretch the metal, leaving a clean aperture through which the plaster is pressed to form the key, and being less apt to dull the dies than an inclined corrugation; secondly, the shoulder is cut off close to the oval bead in making the tongues, and when the metal thus cut out is pressed down and back, forming the tongue, this at shoulder or offset causes the forming of a bend or curve 7 on the end of the tongue, which prevents plast-er from cutting off from main body and dropping behind the lath. This bend or curve on the end of the tongue also forms a binder, running through the plaster and making it hold more securely, besides strengthening the tongue or key, adding to the rigidity of the lath and its bindingqualities.
The corrugations of the sheets are formed only deep enough to stiffen the sheets and allow for the depressed tongues, hence require but a small amount of plaster to fill them and to cover their crowns.
I claim as my invention- 1. In a metallic lathing, formed of a corrugated sheet, tongues Sand 4L cut from the opposing convolutions of the sheets, offset from one another in such a manner lthat they are only partly opposite each other and arranged ICO 8. In a metallic lathing, the combination of the corrugated sheet, having on its face cou- Volutions, a longitudinally-extending bead, a shoulder at each side of said bead, and tongues cut from `ithe forward convolutions, said tongues being provided with a bend 0r curve, substantially as described.
