L. L. SAGEND-OBPH.
METALLIC LATHING- Patented Feb. 24,1891.
UNITED STATES PATENT OFF C LONGLEY LEVIS SAGENDORPH, OF PHILADELPHIA, PENNSYLVANIA.
METALLIC LATHING.
SPECIFICATION forming part of Letters Patent No. 447,085, dated February 24, 1891.
Application filed October 4,1890. Serial No. 367,061- (No model.)
To all whom it may concern:
Be it known that I, LONGLEY LEWIS SAG- ENDORPH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Metallic Lathing, of which the following is a specification, reference beinghad to the accompanying drawings, forming a part thereof.
The object of my invention is to provide a metallic lathing-sheet so formed as to afford an ample and secure locking-surface for the mortar to adhere to and at the same time stiffen or strengthen the sheet, as will be apparent from the description hereinafter given.
In the accompanying drawings, Figure 1 is a perspective view of a portion of a lathingsheet embodying my invention and as preferably constructed. Fig. 2 is an end View of the lathing-sheet shown in Fig. 1. Fig. 3 is a cross-section taken at the dotted line 5c 00, Fig. l, with the mortar applied thereto, illustrating the manner in which the plaster is keyed to the sheet. Fig. 4, illustrates a slight modification of my invention, being an end view of a portion of the sheet.
My improved metallic lathing consists of a sheet of suitable metal corrugated, with loops A cut and forced outward from the concave surface of each corrugation, as shown. It will be readily seen that both faces of my improved lat-hing are the same and are capable of being reversed. The loops A are formed by cutting a slit in the metal at each side thereof and forcing the metal outward between said slits, the apex of each loop preferably terminating below the apex of the main adjacent corrugations B, as shown. The corrugations B are preferably circular in outline, but may be formed V- shaped or rectangular, as shown in Fig. 4.
The plaster 0 may be applied to either face of the lathing-sheet, whichever face may chance to be outward when the sheets are applied, and secured to the walls or ceiling or other portion of the building designed to be plastered.
The advantages of my new and improved lathing are many and apparent. In the first place, a very secure lock or key is afforded for the plaster to adhere to, as will be seen by reference to Fig. 3. The plaster when applied to the sheet is forced in against the loops, which curve inward, said loops causing the plaster to spread out at each side thereof, as shown, and thus cause a secure lock at the rear side of the sheet, the plaster being looked around the loops, which curve outward, as shown in said figure, thus affording double security. The main corrugations or ribs 13 tend to stiffen and strengthen the sheet and at the same time permit of its being bent around girders or oval surfaces without impairing its locking qualities. The sheet of lathing thus formed is easily applied and handled, no sharp points'or corners being present to lacerate the operators hands.
The lathing aforedescribed is designed as an improvement on the lathing patented to me February 25, 1890, No. 422,318, and is superior thereto, on account of the locking-surface produced.
What I claim as new, and desire to secure by Letters Patent, is
1. A corrugated lathing-sheet having loops cut and forced outward from the concave surface of each corrugation, as and for the purposes specified. I
2. A corrugated metallic lathing-sheet having loops cut and forced outward in opposite directions in alternate corrugations, said loops at their end portions being integral with the body of the sheet, as set forth.
3. A corrugated lathing-sheet having loops or retaining portions cut and forced outward from the concave surface of each corrugation, the apex of each loop or portion terminating below the apex of the adjacent convex corrugations, substantially as set forth.
4. A corrugated lathing-sheet having loops out and rounded outward from the concave surface of each corrugation, integral therewith and at right angles thereto, as shown and set forth.
LONGLEY LEWIS SAGENDORIII.
