l WALL COVEBING' Application led January 22, 1931. Serial No. 510,442. I

My present invention relates to the art of wall covering wherein a wall, usually an exterior wall of a wooden building, is to be pro'- vided wit-h a surface giving the appearance of being formed of brick or the like.

Frequently for this purpose metal sheets colored and marked off to represent bricks and the like are nailed to the wooden backing, but the artificiality of such a surface is usua l quite apparent and the general effect is clieap and tawdry.

Again blocks intended to represent bricks and the like have been cemented or otherwise secured by surface attachment to sheets of backing material, such as composition boards and the boards have then been nailed to the wall. In such cases to properly carry out the delusion the blocks must be of a material of different charactei` than that of the backing and diiculty is ex erienced in maintaining a permanent bon or union between the blocks and the backing owing largely to the different coefficients of expansion and contraction of the two materials, and therefore in time the blocks tend to become loosened and in some cases detached from the backing.

One of the objects which I have in view is the provision of an inexpensive wall cover.

ing simulating bricks or the like which may be readily attached to the building; which will resent a close resemblance to a brick or similgr wall, and which will remain permanently in place and indefinitely retain the desired ap arance.

For t purpose I have invented a new and improved wall covering comprising -a composltion board backing preferably of material similar to cellotex which is a com osition formed .of suger cane with bloc s formed of plastic material, such as cement, which are cast in place on the backing and with metallic anchors secured to the backing and having enlarged 'or angular ortions which are embedded in the materla of the blocks when such material is cast.

In the preferrred embodiment'of my invention the anchors extend -forwardly through openings in the bacln'ng board and have extended rear ends to prevent their being drawn forwardly through the backing.`

I prefer to use as anchors sheet metal members havin twin projecting 'portions or flanges whic extend forwardly through ad- ]acent elongated openings in the backing board, and which have a connecting bridge or web ortion which lits against the rear face of t e backing between said o enings.

The ortions of the anchor mem ers which protru e forwardl from the backing board are bent to provi e better anchorage in the plastic material of the blocks, and I prefer to slit such portions of the anchor members to form tongues which are bent alternatel in either direction substantially parallel withI the backing board. A

One or more anchor members may be provided for each block and an anchor member may be of suflicient length to bridge a plurallty of blocks with plain sections without forwardly extending ortions corresponding to the 'spaces or val eys between adjacent blocks.

I have also invented a new and improved process of manufacturing such wall covering. In theaccom anying drawin s wherein I have illustrate a practical em odiment of the principles of my invention, Fig. l .is a face view of a section of my improved wall coverlng.

Fig. 2 is a broken longitudinal section of the same taken along the line 2--2 in Fi 1. Fig. 3 is a plan view of my preferred orm of anchor member.

Fig. 4 is a face view on reduced scale of ,the backing board.

Fig. 5 is a broken plan view showing an anchor member individual to a sin le block. Fi 6 is a longitudinal section ta en along the lme 6--6 in Fig. 5.

' Figs. 7 and 8 are broken longitudinal sec- En i lllhese are indicated generally by the reference numeral 2, and are shown as arranged in three horizontally disposed rows of two blocks each, the top row comprising the 5 blocks 2a and 2b, the intermediate row comprising the blocks 2c and 2d, and the bottom drow comprising the blocks 2e and 2f. Separating the blocks and also running along certain of the perimetral edges of the units are the valleys 3 which are exposed portions of the backing board 1.

rlhe blocks of adjacent rows are in staggered relation so as to brealr joints and also to permit the ends of adjacent units to interlock to form a continuous surface when the units are nailed or otherwise secured to'the building wall.

rJlhe blocks are anchored to the backing board by means of metallic anchoring members attached to the board and having their outer ends embedded in the material of the blocks when the same is cast in plastic condi-l` tion.

Preferably these anchoring members eX- tend forwardly through openings in the backing board and have enlarged rear ends to prevent them from being drawn forwardly through the board.

ln the figures now under discussion l show the board provided with pairs of parallel elongated openings or slot d disposed vertically on the board. At the center of the board a series of three pairs of said slots are arranged in vertical array, the members of the upper and lower pairs being on either side of the valley 3 which intervenes between the blocks of the row, while'the centenpair of slots are covered by the block 2c when the block is cast.

5 represents a metallic anchor member which may be formed of a strip of sheet metal, preferably galvanized, t prevent rusting, and having its edges formed with bent tongues 6 which are inserted forwardly 45 through the slots 4 to protrude at the front of the board and the protruding portions of said slots are slit to form fingers 7 which are bent in opposite direction so that they are substantially parallel with the front face of the board 1 but spaced outwardly therefrom as best shown in Figs. 2 and 3. The central ortion of the anchor 5 bears against the hack face of the backing board, forming a bridge or web which prevents the anchor being drawn forwardly through the openings in the backing board. The plastic materialof which the blocks are formed is cast against the front face of the backing board o with the lingers 7 embedded therein, and thus vidual to the blocks 2a and 2e respectively,

such anchors being only lof suiicient length asesaeae to anchor a single block to the backing board. Similar short anchors 5a are used to anchor the outer ends of the blocks 2h and 2f to the backing board.

ln the case of the block 2d also shown in Figs. 5 and 6 a single anchor 5b of greater width is employed to anchor the block to the backing board. y

ln Fig. 7 l show the use of another form of anchor comprising a pin 8 having an enlarged head 9, the pin being inserted forwardly through a hole 10 in the backing boardy 1 and having an enlarged cap or washer 11 fixed on its outer end as by riveting, which cap is embedded in the material of the block 2. In F ig. 8 I show a bolt 12 having an enlarged head 13 used in asimilar manner, the nut 14 being screwed on the head of the bolt and being embedded in the material of the block 2. f

After the blocks have been cast on the board and have set and hardened and have been properly cured the valleys 3 are pointed with suitable mortar, thus producing an effect in very close simulation to a brick or like wall and also sealing the edges of the blocks at the joints between the edges of the blocks and the backing 'board against the entrance of moisture. When the units are in interlocked relation the joints between the units are simi- Ala-rly pointed and sealed with mortar. j

It is apparent from the foregoing descrip' tion that my improved wall covering forms a very satisfactory and advantageous material for covering the walls of buildings in simulation of a wall formed of brick or other laid units. The blocks may be made of suitable plastic material and colored to the desired tints. The material is readily put up and will maintain its place. The blocks will not become accidentally loosened or detached and the use of bricklayers mortar for pointing the valleys and the joints greatly heightens the resemblance to the wall of brick or other laid units.

A wall covering for simulating bricks and other laid building units, comprising a backing board of composition, blocks cast of plastic material onto the face of the board, and metallic anchor members secured to the board and protruding forwardly therefrom and embedded in the material of the blocks.
