a. G. DAHLBERc-f I WALL FACING Filed June- 17, 1939 Patented Aug. 18, 1942 I WALL FACING G. Dahlberg, Chicago, 111., assignor to The Celotex Corporation, Chicago, 111., a corporation of Delaware Application June 17,1939, Serial No. 279,674

4 Claims.

' ing heavy foundations, or, if applied in remodeling' the added weight is ordinarily not sufiiclent that additional supports are required for walls to which the wall facing comprising the inven tion may be applied. K

The invention involves particularly the application of brick-like elements secured to the outer face of a wall structure whereby the visual appearance is that of a solid brick construction,

but whereas actually the'brick elements are but a fraction of the thickness of ordinary bricks, in

- fact being only about thick or about oneseventh or one-eighth the thickness of an ordi-' nary brick.

The objects of the invention are the provision of a brick simulating wall'construction which is light in weight, is readily applied either to old or new constructions, is firmly secured to the base structure to which it is applied and particularly in connection with which the pointing between individual brick units to simulate mortar joints such is firmly secured and anchored in place; Other and further objects of the invention will become apparent on reading the following specification when taken in connection with the accompanying drawing:

In the drawing:

Figure 1 is a small scale elevation illustrating the application of the invention, a part thereof being shown as finished, the remainder being illustrated as still 'to be pointed up;

Figure 2 is an enlargedsection of the construction shown in Figure 1;

Figure 3 is an enlarged top plan view of the brick unit securing strip;

Figure 4 is a section taken on the line 44 of Figure 3;

Figure 5 is a section taken on the line 55 of gure 3;

Figure 6 is an enlarged perspective view of a modified form of the brick unit securin strip; Figure 7 is an enlarged perspective view of a further modified form of the brick unit securing strip and a Figure 8 is a section showing a modified form 16. The recesses l6 extend, with respect to the of the attachment of the brick unit securing strip to the base member.

In the drawing the brick units or elements are designated by the numeral l0 and the brick unit securing-strips are designated by the numeral I I, the modification of this strip appearing in Figure 6 being designated by numeral [2 and the modification shown in Figure 'l designated by the numeral I3. The plastic or pointing applied between the spaced brick units in order that mortar joints may be simulated is designated by the numeral l4.

The base on which the facing construction is erected is designated by numeral I5 and it is to be understoodthat this base may comprise either a newly constructed base member to which the facing is applied or that the base member l5 may be an old construction, as for example, the wall of an already constructed building.

Inapplying the brick simulating facing 0f the invention to a base such a515, itis preferable that there first be applied over the base or backing IS a sheet of asphalt saturated felt indicated at It, whichasphalt saturated felt serves as a waterproofing course interposed between the base or backing l5 and the applied brick simulating facing units It.

The next step in the application of the brick simulating facing Hi to the base or backing I5 is the application to the face of the base 15 and over the waterproof sheets I6 of spaced mounting strips. of general trapezoidal form appropriately secured, as for example, by nails 20.

The thin brick units or elements Ill, it will be seen, are provided along their longitudinal edges with recesses which with respect to the back of such units and a longitudinal edge thereof are respectively upwardly and inwardly inclined, these recesses being indicated by numeral juncture of the back and a longitudinal edge of unit Hi, upwards and inwardly at an angle of approximately 45 with thespaced walls I1 and 18 of the recesses having a slightly inward convergance whereby the molding of such a slot is facilitated. The side walls I! and ll of the recess l6 are preferably joined by an arcuate wall which completes the recess.

It is to be noted that due to the construction of the recess l6 that there is formed at the Juneture of the side walls I! of recess I6 and longitudinal edge of the unit ill, a line juncture IS, the advantage of which will hereinafter become apparent.

' In applyin the unit securing strips l I to the backing or base I 3, they are ordinarily applied horizontally and parallel, spaced on centers such that an individual brick unit II will fit snugly between adjacent securing strips II.

It will be readily understood that when two properly spaced securing strips II have been secured'to the base or backing ii that individual brick units ll may be entered between the such strips at the ends thereof and slid along between this pair of strips II to the final position-which the brick unit is to occupy on the finished struc-- ture. It is also to be understood that after one brick unit It has been entered between a pair of spaced securing strips II that other units It may be fed in between this pair of strips to fill the space between the strips, and that on any wall to which the application is being made additional properly spaced strips ll may be applied and brick units ll likewise inserted between such pairs of strips ll until the entire surface of the wall has been covered. Still further it is to be understood that the securing strips ll need not be applied horizontally, but that if desired they may be applied on a slant or vertically provided, however, that adjacent pairs of strips l I shall be parallel and the strips shall be uniformly spaced, excepting, that if desired brick units ll of different widths may be used in different courses, in which case the securing strips il between which the units it are mounted shall be appropriately spaced to receive the brick units II of the width other than standard. In applying the facing to a base or backing II, the securing strips ll may be applied to the entire facing and all of the brick units ill may be inserted between the strips but if the construction proceeds in this manner there must be left in each row horizontal sufficiently unfilled space so that adjacent brick units Ill may be spaced approximately so that a uniform pattern of mortar joint simulation may be applied.

After the brick units l0 have been erected on the face of the base or the backing I! in accordance with the foregoing, the horizontal and vertical spaces between adjacent brick units It should be appropriately pointed with a mortar joint simulating material which preferably will comprise an approved caulking compound, although it is within the scope hereof the open joints between adjacent brick units III may be pointed up with any substance which will satisfactorily simulate the,desired mortar and also it will be understood that in pointing up the spaces between adjacent brick units It these spaces can be completely filled up fiush with the surface of the brick units ll, or these spaces may be filled only partially in depth so that the surface simulated mortar joint is slightly depressed with respect to the outer faces of the brick units III.

In order that the caulking compound or mortar joint simulating material indicated at l4 may be firmly secured in the space between adjacent brick units ill, particularly with respect to the horizontal joints, it is preferred that the securing strips ll be provided with keying openings such as 2|, which keying openings may be of any suitable form for receiving appropriate keying portions of the pointing substance l4. In Figure 1, certain of the keying openings 2| are indicated as circular, whereas others are indicated as slots which forms are readily apparent on viewing the fi ure of the drawing.

The securing strip ll illustrated in Figures 2. 3. 4 and 5 of the drawing may be formed of wood or any suitable substitute therefor. for example, this strip may be formed from what is known as fiber insulation board thoroughly impregnated, either before or after the strip II is cut to form, with some hardening and solidifying substance such as asphalt, a synthetic resin or other equivalent saturant.

Keying openings 2| provided in the securing strips ll may, if circular, be formed by drilling or by punching and particularly if the material of the securing strip II can be punched, the shape of the keying opening 2| may be alternatively'triangular or such other shape as may be determined by the shape by the punch used for punching the openings in the strip.

A very satisfactory keying recess 2| and one which very definitely keys the pointing substance 14 to the securing strip II is illustrated in detail in Figures 3, 4 and 5 wherein from an inspection of the drawing it is readily apparent that adjacent pairs of keying recesses 2| are inclined one toward the other that a definite wedge keying action is obtained. It will also be seen that these keying recesses 2i have been formed as by cutting with a small rotary cutter suitably inclined and sunk into the securing strip l I to a depth slightly less half of the diameter of the cutter used.

As an alternate of the wood or other fibrous securing strip II as above described there may be employed a formed metal securing strip i2 shown inFigure 6, which securing strip I2 is formed from a strip of suitable metal folded with flanges 25 having suitable perforations 28 therein through which nails or other suitable securing means may pass for securing strip i 2 to the base or backing IS. The flanges 25 of the strip l2 are folded outwardly from the formed securing strip which is suitably formed to a substantially trapezoidal section to correspond in form to the wood or fiber securing strip Ii. In this sheet metal securing strip l 2 there are in the upper face thereof provided perforations 21, which serve the function of keying the pointing substance into the joint spaces between adjacent brick units It in the same manner that the previously described keying openings 2| in securing strips ll serve this function A still further modification of the securing strip Ii and for many purposes the preferred form thereof, is indicated at l3, Figure 7. This securing strip I3 is formed Of a strip of suitable metal which is folded into substantially trapezoidal form but with the edge P rtions 30 and ti overlapping as is clearly apparent and in addition the broader face 32 of this sheet metal strip is slightly arched or bowed as is clearly apparent on inspection of Figure 7 of the drawing. The edge portions of the strip of metal which is formed into securing strip I 3 are provided with registering and overlapping slots 32 and 33 whereby a nail 34 entered through a suitably provided opening in facing 32 of strip l3 may pass through these slots 32 and 33 and serve to secure strip [3 to the base or backing II.

With respect to the securing strip l3 it will be seen that when this is applied tothe base or backing I I with securing nails 34 driven up just sufficiently to hold the strip against the face of the base I! that subsequently after the brick units II have been inserted between adjacent pairs of such strips II that then the nails 34 may be driven somewhat more firmly into'place as with a nail set or the like. This due to the arch form of the face 32 of the strip l3 as nail ,34

is driven in will tend to flatten out facing 32 to a plane surface with a consequent widening of the overall width of the strip l3 which is possible because of the slots 32 and 33 in the overlapping portions 30 and 3| of strip l3. Expansion of or widening of the strip l3 in the manner just described, it will be readily understood, serves to tightly wedge between adjacent pairs of strips IS the bricks l which have been previously inserted therebetween, that is, the use of an expansiblesecuring strip l3 provides for adjustment of any slight error made in spacing of the strips l3 or the application thereof to the backing member l5.

The expansible securing strip l3 just above described may be provided in its top surface with keying openings similar to or equivalent to the keying openings at 21 provided in securing strip l3 of Figure 6.

In connection with the above construction, the brick units It! may be of substantially the dimensions of a side face of an ordinary brick and of a thickness of approximately /2", or if desired, may be of any suitable width, length and thickness providing, of course, that such are kept within reason, as for example, not so thin that it is impractical to providea slot IS in the edges of the bricks l0, nor so thick or of such'width and length dimensions that the weight of the unit is excessive. While it is contemplated that the construction described will utilize burnt clay brick members III to provide a finish appearance corresponding to that of a solid brick construction, it will be understood that the units l0 may be composed of any suitable material from which these units may be molded or cut and that if the units are to be exposed the material should be such as will stand exposure, whereas, if the units are not to be exposed materials therefore which would otherwise be unsuitable, may be utilized, as for example for interior work, the unit Ill may be molded from gypsum.

While, as above stated, a plastic caulking compound suitably colored is preferred for pointing the joint spaces between adjacent brick units III, as 'for example a readily available plastic and non-hardening caulking compound having as the base thereof paint skins, it will be readily apparent that the jointsv between adjacent units may be pointed up using mortar prepared from sand and lime or sand and cement or other suitable cementitious substance, such being practical particularly due to the fact that in the shallow joint over the securing strips II the such pointing substance will be keyed into the Joint by the 7 keys provided in the securing strips II, I! and I3 as has been previously described in detail.

Whereas, in connection with the above description of the invention it has been assumed that the base or backing material II is lumber or other material into which nail may be driven and in which nails will hold, the application may alternatively be made to a base or backing ll of manufactured fiber board readily available under the descriptive name of cane fiber insulation board. Cane fiber insulation board and generallysimilar backing material, the attachment may b made by wire staple 40 or the equivalent which is forced through the securing strip H and the fiber insulating backing l5 and which has the terminal portions II of its legs clinched at the back of the fiber insulating board backing l5 for secure attachment of securing strip II to the fiber insulating board backing l5.

In a wall facing construction having a plurality of facing elements, a mounting strip for afilxing' th facing elements in the wall construction, the mounting strip formed of sheet material arranged in the form of a trapezoid having of its parallel sides, its wider side bowed outwardly and its narrower side formed by the edges of the sheet material in overlapping relation, and the overlapping portions having therein elongated registering slots.
