COMPOSITION LATH.
. Specification of Letters Patent.
Patented Dec. 16, 1919.
f Application filed August 16, 1918. Serial No. 250,198.
bodying means whereby a plurality of keys or bonds are formed by the plaster or mortar and firmly engaged in key ways or openin s in the body of thclath.
l Vith the above and other objects in view, the invention consists in the construction, combination and arrangemcntof parts, as herein described, illustrated and claimed.
In the accompanying drawing Figure 1 is a fragmentary plan View of the improved composition lath.
Fig. 2 is a fragmentary cross through the same.
Fig. 3 is a section similar to Fig. 2 showa modification in the structure of the lath.
The improved lath has, as the essential features thereof, a backing sheet 1, a face sheet 2, an interposed fillingor body 3 of plastic material, and a plurality of key ways section or slots 4, as shown in the drawings. The
sheets 1 and. 2 may be of any suitable flexible material, such as paste-{board or card board and the filling or interposed body 3 may be composed of plaster of Paris, or some cement composition, such as will adhere ;firmly to the sheets 1 and 2 and serve to cement the same together. Thethickuess of the filling 2 is such as to provide a complete lath of the necessary thickness, the thickness of the lath being governed by the nature of the structural work in connection with which the lath is used.
. In Fig. 2, the sheets 1 and 2 are shown as flat and parallel to each other. In Fig. 3, a
employing a flat backing sheet 5,. a corrugated face sheet 6 and a filling '7. The members 5, 6 and 7 may be formed with the same material stated above in connection with the members 1, 2 and 3 and the corrugations 8 of the corrugated sheet 6 may extend either vertically or horizontally but preferably-thelatter, so as'to more effectively support the mortar or plaster applied to the face sheet 6. The key ways or openmodified form of the lath is shown, the same ings tare preferably elongated horizontally in the form of slots, as indicated in Fig. 1, so that they will better supportthe body of the plaster applied to the face of the lath.
' here the corrugated form of lath is employed, the key ways 4 will extend length-' wise of the valleys or depressed portions of the corrugation or corrugations as indicatedin Fig, 3, so that the keys whichzenter said key Ways will project from the thicker" portionsiof said body of mortar or plaster.
It will, of course, be understood that the laths may be manufactured in any desired size as to length and width and they may also be of any desired thickness.
'1 claim:
1. A composition lath comprising a face sheet, backing sheet, and an interposed body of plaster, one of said sheets being cor-' rugated and the corrugations being inter,- nally filled with said body of plaster.
2.;A composition lath comprising a face sheet, a backing sheet, and an interposed body of plaster, one of said sheets being corrugated and the corrugations iheing in ternally filled with said body of plaster, the lath as a whole being formed with key-receiving openings elongated in the direction of length of said corrugations.
In testimony whereof I aflix my signature.
