METALLIC LATE.

application filed June 19,

To all whom it may concern-.-

Be it known that I, l lINOR E. {,TiiAMnn-n- LAIN, a citizen of the United States, residat Louis, Missouri, have invented a new and useful Metallic Lllll, of which the following is a specification.

This invention relates to improvements in metallic laths, and consists in the novel construction hereinafter disclosed.

an object of the invention is to provide an improved lat-h arranged for use in reinforced concrete construction for supporting plaster and the like.

Another object of the invention is to provide a lath formed as constitute a binding member for plaster, cement or the like, in combination with supports for the same, said supports being suitable for reinforcement of concrete wall construction.

Additional advantages of the invention will be apparent from the following detailed description thereof taken in connect-ion with the accompanying drawing, in which Fig. 1 is a horizontal section taken substantially on the line 11 of Fig. 2.

Fig. 2 is an elevation of the construction.

Fig. 3 is a perspective view of the supporting members for the lath with the lath attached thereto.

Fig. 4 is a cross section on the line 4l4l of Fig. 1.

Fig. 5 is a detailed view of the lath sections showing the method of joining the adjacent ends. 1

In the embodiment of the invention illustrated in the drawing there is a Wall structure composed of two parallel Walls. The wall structure comprises a plurality of studs, each of which is composed of a section of sheet metal folded to provide a wing 1 of double thickness and two wings 2 of single thickness projecting laterally from the wing 1. The studs are arranged with the wings 1 of double thickness extending toward each. other and the wings 2 of single thickness extending parallel with the surfaces of the wall. The wings of double thickness of each pair of studs are reinforced by con necting plates 3 which are spaced to receive and support the studs in the manner most clearly illustrated in Fig. 3 of the drawing. The plates 3 are united in the central portion thereof and flare outwardly slightly, forming spaced leaves 1 at each end between which spaced leaves the double wing portions 1 of the studs are received. The ends Serial No. 569.305.

:0 provide latermping inem ars 2 of the studs.

the studs in poof connecting mcmb con t" scribed are o tached to each of studs a iced intervals.

tltiescmend... hey tend to rein- .h other, that together they 7 substantial rigid frame for the concrete structure.

This trams also constitutes a support for the trans; lath members. The lath members are made up from elongated strips of metal folded to provide a baclr wall 6 and having side walls 7 converging toward each other, the upper ends of the side walls 7 being flared outwardly to form flared flanges 8. The lat-he are thus constructed so as to provide a channel with a shoulder 9 therein on either side, formed by the juncture of the two deflected members 7 and S. It will be apparent, therefore, that the form of the lath provides means for anchoring the wall surface of cement or plaster laid against the lath structure, the shoulders 9 preventing the hardened mass from pulling out of the lath channels. In order to further anchor the mass the back wall of the lath members is perforated at spaced. intervals by deflecting a portion of the wall loaokwardly forming openings 10 and tongues 11, the wall forming material ontering these perforations and upon hardening locks in position.

In order to form a convenient means of securing the laths together at the ends one end of each lath section is flared outwardly at 12 to form a seat for a portion of the adjacent end so that a telescoping connection between adjacent ends of the lath sections may be effected, as clearly illustrated in Fig. 5 of the drawing.

U Wlll be understood that a plurality or the lath members are attached to the frame structure, the laths being secured to the frame at spaced intervals. In the drawings there is illustrated convenient means for securing the laths to the studs. ()ne method comprises the use of nails 13 inserted through the back wall 6 of the lath and entering the Space between the leaves of the web 1 of the studs. The other method comprises the ttor mation of tongues 14 stamped out of the face of the wings 2 of the studs, said tongues being staggered and embracing the upper and lower edges of the lath member. Either method may be used or th two methods may be used conjointly as shown in Fig. 2, by securing alternate series of the laths with nails and tongues.

When the laths are secured in position on the frame they serve to reinforce and laterally brace the frame so that when the members are united a rigid reinforcement for the concrete wall structure is provided as well as providing for a wall-surfacing receiving construction.

A wall constructed to utilize the elements oi the invention may be built very economically and the resulting structure is very strong and durable.

I am aware that the invention may be modified in Various particulars without departing from the nature and principle thereof.

1 do not restrict myseli unessentially, but what I claim and desire to secure by Letters Patent is 1. A. metallic lat-h, comprising an elongated section of sheet metal composed of a substantially flat back wall, outwardly converging side walls integral with the side edges of said back wall and forming a dove tail channel the widest portion of which is adjacent to said back wall, and flaring flanges integral with said side walls, said side walls and flanges forming an outside channel at each side 01" the lath.

2. A. metallic lath, comprising an elongated section of sheet metal composed of a substantially flat back wall, converging side walls integral with the side edges or said back wall, flaring flanges integral with said side walls, said side walls and flanges forming an outside channel at each side of the lath, and tongues in connection with and extending in a direction away from said back wall.

3. Laths, comprising longitudinal series of sections each of which is composed of a substantially flat back wall, converging side walls integral with the side edges of said back walls, and diverging flanges integral with said side walls, sald slde walls and flanges forming an outside channel at each side of each leat, and a telescoping connection uniting said series of sections.
