UNITEDl STATES PATENT OFFICE.
JOHN L. BRABYN, OF NEW YORK, N. Y.
LATI-I FOR BUILDINGS.
Specification of Letters Patent No. 17 ,5.50, dated June` 16, 1857.
T o all whom it may concern:
Be it known that I, JOHN L. BRABYAgof the city, county, and State of New York, have invented a new and useful Improvement in Lathing the Vv'alls and Ceilings of Buildings Preparatory to Plastering the Same, the use of which is calculated to lessen the expense of plastering both by the saving of labor and material; and I hereby declare the following to be a full, clear, and exact description of my said improvement, reference being had to the drawings accompany ing and making part of this specification.
My improvement consists in the manner of preparing and applying the laths, and first in preparing them I form a groove or slot in one or both edges of the lath, by cutting out a certain portion of one side in the form of a half dovetail, or any other shape, so that when combined with its fellow or when two grooved edges, or one grooved and one plain edge are placed together there shall be formed an interstice -or groove in the form of a dovetail or its equivalent for the purpose of holding the plastering material firmly to its place when crowded or pressed into the interstices so formed. That portion of the lath which remains of full width which will always form the back side when properly laid, will constitute a solid support for the mortar, thus preventing it from pressing through between the laths, as is always the case where the interstices are formed by laying the lath with a space between them, and allowing the mortar to form a clench behind the laths. In the im proved method above described, the clench is formed by the groove in the lath being widest at the back, and this groove and the solid support for the mortar are both formed by or in the laths and entirely independent of the wall or ceiling to which they are fastened, the laths being laid with close joints at the back instead of a certain distance apart as in the old method. By this arrangement it will be readily perceived that although the lathing may be furred ofi' as it is termed, yet no extra quantity of mort-ar will be required, as the mortar does not press through and fall down behind the wall, but simply fills up the grooves provided in the lathing. l
Another advantage will readily be per; ceived, that even where the lathsare applied directly upon a brick Wall without being furred off, which is often the case, the solid back of wood, formed by `the peculiar construction, and application of the laths, will prevent in a great measure the dampness of the brick wall from .communicating wit-h the plastering as the wood is not so good a conductor of moisture as the mortar itself would be.
In frame buildings a very greatadvantage is derived from the use of this improvement as the lathing forms a tight ceiling of itself, thus contributing largely to the warmth of the interior of the buildings. The foundation of the wall being much more substantial, there is less liability of the walls cracking, and the weight of the plasteringbeing much reduced there is consequently less liability of its falling off. This is of particular advantage in overhead walls, as it is frequently the case that large quantities of the wall come down,` simply from its own weight when put on in the old method.
Another advantage is derived from the increased facility of laying the laths, as no regard is to be had to the spaces between them, the edges being placed tight together, and the interstices formed with mechanical eXactness. The wall will be much more solid and firm, as the mortar can be pressed upon the lathing with any degree of force that may be desired, which is not the case in the old method, as the harder it is pressed the more it is forced through between the laths and wasted behind them.
The grooves are indicated in the drawing by the letters (a a.) and the back support by the letters Z) lhat I claim aslny invention, and desire to secure by Letters Patent, is-
The forming of the interstices in the form of a dovetail or its equivalent and the back support for the mortar in the laths themselves, and entirely independent of anything that may be placed behind them, by grooving one or both edges of the lath on end side and leaving the other side the full width, so that when the same are in place their edges shall join at the back side to prevent the plastering material from pressing through between the laths, the grooves forming the clenches to hold the mortar firmly in place, substantially as set forth.
JOHN L. BRABYN.
