Description
' MINOR E. CHAMBERLAIN, OF LEBANON, MISSOURI.
METALLIC LATH.
Application filed October 4, 1915.
0 all whom it may concern Be it known that I, MINOR E. CHAMBER- LAIN, a citizen of the United States, residing at the city of Lebanon, county of Laclede, and State of Missouri, have invented a new and useful Metallic Lath, of which the following is a specification.
This invention relates to improvements in metallic'laths for use on reinforced concrete construction and for supporting plaster and the like.
An object of the invention is to provide an improved lath preferably composed of sheet metal folded to form oblique flanges on its side edges for, the purpose of providing engaging portions for the concrete or plaster, whereby secure bonding engagement will. be effected to hold the concrete or plaster.
Another objectis to provide a lath of the character and for the purpose mentioned,
in combination with improved spacing and clamping devices for securing the laths to their supports.
Other objects not requiring specific mention will appear from the following detailed description, reference being made to the ac-' companying drawing in which I have illustrated a preferred embodiment of the invention and in which Figure 1 is a sectional view of a wall structure having my improved laths embodied therein. Fig. 2 is a detailed view illustrating the laths in side elevation. Fig. 3 is a sectional viewon the line 33 of Fig. 1, illustrating the concrete or plaster engaging the laths. Fig. 4 is a perspective view illustrating one of the laths secured to its support. Fig. 5 is a detailed view illustrating the construction of one of the laths and particularly illustrating the extended tongue or projectionon one end and the slot on the opposite end which constitute means for securing the laths together in longitudinal series. Fig. 6 is a side elevation of the lath illustrated in Fig. 5. Fig. 7 is a cross sectionalview on the line 7-7 of Fig. 5. Figs. 8 and 9 are detailed views illustrating the devices for securing the laths to their supports.
In the embodiment illustrated in Figs. 1
and 3, there is a wall structure composed of two parallel wall faces. The wall structure comprises a number of studs. each of which is composed of a section of sheet metal fold- Specification of Letters Patent.

Serial No. 53,925.
ed to provide a wing 1 of double thickness and two wings 2 of single thickness of the sheet. The studs are arranged in pairs with the wings l of double thickness extending toward each other and the wings 2 being par-v allel with the surfaces of the wall. The wings of double thickness of each pair of studs are reinforced and braced by connecting plates 3 which are spaced to receive the wings 1 as illustrated in Figs. 1 and 4, and the ends of which abut against the wings 2. The wings 2 constitute supports for the laths and for the lath-securing devices, so that after the laths have been secured in con nection with the studs the concrete or plaster may be applied to complete the wall.
The laths 4 are of novel construction and are preferably, though not essentially. composed of sheet metal. The side edges of each lath are folded obliquely toward each other to provide oblique flanges 5 between and upon which the concrete or plaster may engage when applied. The flanges 5 are between the studs and across the face of the studs, and the edges of the sheet metal are folded flat upon the central portion thereof as indicated at 6. Between the flat portions 6 and the flanges 5 the edges of the sheet metal are shaped to provide flaring portions 7 for better engagement with the concrete or plaster. Also at suitable intervals the lath may be provided with holes or perforations 8 of suliicient size to permit portions of the concrete or plaster to be pressed therethrough and to engage upon the inner side of the lath, thus providing gripping extensions for the concrete or plaster. Each'lath is also preferably provided with a tongue 9 at one end and with a slot 10 at the opposite end so that the tongue t of one lath may be passed through the slot 10 of the adjacent lath and clamped, thus securing the laths together in longitudinal series. The devices for securing the laths to the studs comprise plates 11 adapted to bear against the surfaces of the wings 2 of the studs and being of sufficient length so that the ends thereof may be folded to clamp upon said wings 2 and thus secure the plates 11 in engagement with the studs. Each plate 11 is provided on its side edges with slmuldered flanges 12 which receive the flat portions (3 of'the laths and thereby rigidly bind the laths in connection with the studs. By means ofthese devices the laths may be secured to the studs in par allel series in position for the application of the concrete or plaster, which may be applied by use of the usual implements for such purposes, such as trowels .or the like. The wall formed in this manner includes two separate wall faces, as lllustrated in Figs. 1 and 3,
each of which is supported upon a separate or distinct series of laths secured to a separate or distinct se'rles of studs, and it will be noted that the studs of one series are connected with the studs of the other series so that the tWoWall faces may be rigidly sup: ported with respect to each other. The plaster or concrete applied to thelaths becomes bonded'therewith by the hardening action of the plaster or concrete and, by engaging in the spaces formed byjthe flanges 5,
forms a strong union. The flanges formed on the side edges of the laths-reinforce or strengthen the lathsbetween the studs so that the laths do noteasily bend or press inwardly under the pressure of the plaster or concrete When'being applied thereto. The
laths may thus be composed of comparatively thin sheet metal and yet be sufficiently rigid sothat they vill not yield or head during theapphcahon d the (C(llltl'ltt a hat I claim and desire to secure by Letters Patent of the United States, is
1. A metallic lath comprising a section of sheet metal having a substantially fiat back surface and having its edges folded to provide flange portions on the outer side of the section of sheet metal, and said flange portions ha'virfg parts thereof pressed flat against the outer surface of the sheet metal section.
2. A metallic lath con'iprising a section of sheet metalhaving its side edges folded to provide outwardly extending flanges and having portions of said flanges pressed fiat against the outer surface of the sheet metal. section, and said section having holes therethrough between the flanges on opposite sides thereof.
In a structure of the character described, series of metallic laths each being composed of a number of sheet metal sections arranged end to end, an interlocking tongue and slot connection holding the sheet metal sections of each series together end to end, and each of said sections being folded to provide outwardly extending flanges on the upper and lewdedges thereof and hailhg portions 0t and [huge pi'cssdl lht l i l I, t at the (lllitl' Slll'hltt d the tllttt lllthll sections.
In witness whereof, I have signed this specification in the presence of two subscribing witnesses. I
