FlRE-PROOF-TILE FURRING.

SPECIFICATION forming part of Letters Patent No. 257,366, dated May 2, 1862,

Application filed October 29. 1880.

To an whom it may concern:

Be it known thatwe, GEORGE M. MOULTON and Eenns'r V. J oHNsoN, of the city of Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in the Manufacture and Construction of Fire- Proof-l urring Tiles; and we do hereby declare that the followingis a full, clear, and exact description thereof, reference being had to the accompanying drawings, which make a part of this Specification.

Our improvements relate, first, to the manufacture of a tire-proof tile for the purpose of furring for outside walls, vaults, or other parts of buildings, where freedom from dampness and its deleterious effects is required; second, to the manner of laying the tile in place, whereby a continuous airspace is obtained over the whole of the furred surface, and also to the method of securing the tile by means of nails and mortar, as herein described.

Our invention consists in the form and application of the furring-tiles for the purpose required.

\Ve propose to use baked tire-clay for making the tiles, but are aware that any non-conducting material suitable to be made in this formsuch as cement composition, porous terracotta, plaster-of-paris, and various other materials-could be used for the purpose. In making the furring-tiles of baked clay they are made in pairs, in ahollow form, and are thus run through the die, dried, and put into the kiln for burning; but when they are delivered at their place of use they are split apart through a groove at each end, which allows them to hold their shape during the process of manufacture, but which yields readily to the tap of a masons trowel when applied. to separate them. The tile when made of clay or other suitable material, may be readily cast in molds or shaped by hand, but we prefer the manufacture described as producing the best results for the least money.

In the accompanying drawings, Figure I is an isometrical view of a brick wall furred with tile furring. Fig. II is a horizontal section through the furring, showing method of application.

Like letters refer to like parts in both of the figures.

(No model.)

A is a brick wall, which we represent furred on its insideface with the fireproof-tile furring B. Each separate tile 1) is made to project from the wall, as shown, thus leaving the air-spaces d. This projection can be made more or less at will by manufacturing the tile with the endf to. the depth required. Each tile is laid to break joint on every alternate course, thus pieces 71., as shown.

The principal purpose for which we have designed this furring-tile is for use in the construction of substantial buildings, where it is found necessary by reason of the porosity of brick walls to use some formot' material that will project from the interior face of the wall, thus leaving an air-space, and at the same time present a suitable surface on the other side to receive the plaster coat and finish. The usual plan for accomplishing this'result has been to tack strips to the brick wall forming the re quircd projection, and then nail wood or iron laths to the same, or, as is occasionally done, to build the main walls of sufficient thickness to allow them to be builtwith a small airspace in the center, called cavity walls.

The objections to the foregoing methods are numerous; but the following reasons will be sufficient to explain the necessity fora radical changein this system of furring for buildings. When wooden laths are secured to the strips mentioned the effect, when plastered, is to pro duce a surface that is easily distinguished from the remaining sides of a room by the dark discolorations of the laths and strips showing through the plaster. This is caused by the moisture coming through the walls and being absorbed by the wood, thus dampening the plaster sufficient to accumulate dust and present an unclean and irregular appearance. This fact is equally true of iron lath, the moistare causing it to rust and discolor the plaster,

and in addition the changes in temperature subjects the iron form of lath to the damaging effects of expansion and contraction, causing the plaster coat to be cracked and unsightly. The objection and consequent unpopularityot' the cavity form of wall is the additional weight, space, and material required byits use, rendering it too expensive for the purpose. 'By the use of the fireproof-tilefurring all these defective features are obviated, while at the same time a substantial, economical, non-decaying, andfire-proof material is obtained with all the advantages but none of the defects of the numerous forms of furrim at present in use.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

The combination of the furring-tiles I), made in the shape shown, applied to a brick or other form ofwall,with the nails 0, and forming theairspaces d, whereby a continuous circulation of air is'allowcd over the whole of the furred surface, thus avoiding dampness and affording means for ventilation, all as substantially set forth and described.
