METALLIC LATHIANG.

SPEGIFIQATION forming part of Letters Patent No. 533,000, dated January 22, 1895.

Application filed Jul 24, 1894. Serial No. 518,444. (No model.) atented i ng a d ecembe 1 89 24,267m11d in Belgium July 18, 1894,11'0- 111,050-

To all whom it may concern:

Be it known that I, THOMAS LEWIS BANKS, a citizen of England, residing at Lindores, 3 Branstone Road, Kew Gardens, London, in the county of Surrey, England, have invented a certain new and useful Improved Manufacture of Metallic Lathing for the Ceilings and Walls of Buildings, (for which I have obtained Letters Patent in Great Britain, dated December 16, 1893, No. 24,267, and in Belgium, dated July 18, 1894, No. 111,050,) of which the following is a specification.

My invention relates to an improved manufacture of metallic lathin g for the ceilings and walls of buildings, more particularly in relation to fireproof construction, which shall afford an effectual key to plaster or cement no matter in what position the lathing be placed, whether horizontally, vertically or inclined, while at the same time the manufacture is inexpensive, the amount of metal employed for afiording a given strength is a minimum, the metal when plastered being embedded and thus protected from the flames both on the inner and outer surfaces, and the lathing is capable of being readily bent and produced in any dimensions both as to length and width.

According to myinventionI construct such lathing of helically coiled strips of metal or fiat metal wires, such strips or wires being interlaced or woven in any desired manner for forming network with rectangular, diamond, or other shaped meshes, the coiling of the strips being such as to afford an effectual key to the plaster or cement on each side of each of the meshes, in addition to which interstices are formed at the crossing;- points of the strips which afford an additional key.

Figure l of the accompanying drawings shows a construction in which the metal strips or flat wires A are formed with two complete helical coils to each mesh, formed by thecrpssing'of the strips. Thus when the plaster or cement is laid upon such lathing it will be at forded a perfect key by reason of its pene tration into the hollow spaces formed by the coils. 7

- The twists may be widened outat intervals at a a for enabling the interweaving of the strips to be effected without causing labor in bending.

Fig. 2 shows a form of coiled strip constructed by a number of round wires placed side by side.

I claim as my invention-- Metallic lathing for ceilings and walls constructed of interlaced coiled metal strips, the coils forming hollow spaces into which the plaster on each side of each mesh may pene trate, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 12th day of July, A. D. 1894.

:r. LEWIS BANKS.
