6 Claims.

This invention relates to masonry simulating material, and particularly to building covering material, such as siding material, formed on a panel foundation or base which is coated with water-proofing material and surfaced with granular material arranged or designed to simulate a plurality of masonry elements, such as brick faces, and mortar joints therebetween.

Considerable difficulty has been experienced heretofore in the manufacture of material of this character in obtaining a good simulation of masonry material, such as brick work. Thus, up to this time, it has generally been found, particularly with respect to material which is laid in co-planar, as distinguished from over-lapping relation, that most attempts to employ two colors of granular material upon the panel to simulate masonry faces and mortar joints, respectively, have been subject to exposure of the panel character of the built-up wall surface. This has been due to the fact that material such as asphalt, used to water-proof the panels and to cause the granular facing material to adhere thereto is of a dark color which is exposed at the edges of the panels. Hence, if the panels do not fit tight-- ly and exactly one against the other at their abutting edges, the color of the water-proofing material is exposed at the cavities or joints, between the panels. On the other hand, it is practically impossible to achieve a uniform tight joint between panels by reason of the fact that the composition or insulation board which is generally used as a base for material of this character cannot be made of accurate size, and the manufacturers tolerances for dimensions are usually plus or minus a: of an inch. These unavoidable tolerances result in the occurrence, in

" a surface of assembled panels, of a plurality of cavities at the joints or between the edges of adjacent panels. Various attempts to overcome this deficiency have been made but to the best of my knowledge the only methodwhich has heretofore been successful in material using panels laid up in co-planar relation is that illustrated and described in the patent to L. H. Mattes, No. 2,205,798, dated June 25, 1940.

I have found, however, that there is another method by means of which the existence of cavities at panel joints may be concealed efficiently.

The primary object of my invention is to provide a novel construction of masonry simulating material by means of which the joints between adjacent co-planar elements or panels of said material may be concealed effectively.

character having masonry simulating faces of one color and mortar joint simulations of a sec ond color including mortar joints extending to the edge of the panel at two adjacent sides thereof ,with a narrow band of material of the-same color as the mortar joint at and project g from the other two sides of the panel to abut the adjacent panel and thereby conceal any cavity be-- said coating in a patterned arrangement simulat- A further object is to provide an article of this ing masonry faces and intermediate mortar joints, with a narrow band of granules of mortar joint color applied to certain edges of said c ts ing in a plane at an angle to the coating.

A further object is to provide an article of this character having spaced masonry simulat" ing areas thereof coated with granules of one color and the intermediate areas thereof coated with granules of a second color, wherein granules of the second color are applied at the edges of the panel complementary to the edges to which mortar joint simulations extend, and wherein one or more margins of the inner mortar joint simulating faces are provided with a narrow groove to complement the appearance of the joints between the edges of adjacent substantially abutting panels.

Other objects will be apparent from the description, drawing, and appended claims.

In the'drawing:

Fig. 1 is a view in face elevation of a member embodying my invention.

Fig. 2 is an enlarged fragmentary sectional view taken on line 22 of Fig. 3.

Fig. 3 is an enlarged fragmentary sectional view taken on line 2-2 of Fig. 1 and illustrating a slightly modified embodiment of the invention.

Fig. 4 is an enlarged fragmentary sectional view illustrating a joint between adjacent panels leaving a cavity therebetween and also illustrating the manner in which the cavity is concealed.

Referring to the drawingwhich illustrates the preferred embodiment of the invention, the numeral Ill designates a panel of composition or insulation board such as Celotex or Insulite.

The panel I0 is made ofany desired size and is provided at two adjacent edges with inset shiplap flanges II, and is undercut at two opposite edges to provide reduced thickness flange portions l2 complementary to the ship-lapv flanges II. I The innermost faces of the flanges Hl2 lie .of the adjacent panel.

in the same plane and the transverse dimensions of the said flanges are the same, so that panels may be laid in abutting relation to provide a weatherproof ship-lap joint therebetween witha brick face, the asphalt coating I3 is covered with granules I5 of any suitable material. Where a brick face simulation is desired, the granules I5 will preferably comprise small substantially uniform particles of ordinary ornamental or. face brick formed by crushing regular face brick and grading the particles for size. Any other de-' sired material such as small stone particles, grit, or the like may also be used.

' At the narrow elongated areas I6 between the faces I4, whosesize and location correspond to ordinary mortar joints, the coating I3 is covered with granules II. The granules I! are preferably of smaller size and of a different color than the granules I5. Also, the areas I6 are preferably depressed so that the granules I'l lie substantially below the piane'of the granules I5 and, hence, give a good simulation of a raked mortar joint.

- If desired, narrow grooves I8 may be impressed at one or more edges of each of the mortar joint simulating faces I6. As here illustrated, the grooves I8 are formed adjacent the lower edges of all faces I4 except those of the lowermost row or course of said faces on the panel. vertically extending grooves I8 are provided in the vertical mortar joint areas I6 adjacent the left-hand edge of each masonry simulating face It, except as to those faces I4 which extend to the left-hand edge of the panel. These grooves I8 are preferably so formed as to create an enhanced shadow-line efiect, inasmuch as the' depth of depression of the areas I1 is obviously limited and may not be sufficient to create a satisfactory actual shadow. The grooves I8 are so formed that the granules I'I line the same and do not expose the color of the thermo-plastic coating I3.

As best illustrated in Figs. 2 and 3,I propose to apply at the edges of the panel, such as the lower and left-hand edges as illustrated in the scribed is applied to a wall or other building face with the ship-lap flnages II and I2 interfitting as tightly as possible, the granular material I9 on one panel abuts positively against'the edge In the event thepanels are out of true and any cavity exists the'rebetween, in the nature-of its to /1 of an inch, the

granules I9 serve to span said cavity and thereby to conceal the existence thereof and also to conceal the color of the thermo-plastic material which would otherwise be exposed at said cavity. In this connection, it would be observed that the thei'mo-plastic material I3 is sufficiently yielding that the granules I9 may be pressed therein at such points of the panel where full contact between the panels is possible. Hence, the construction involved is one wherein the projection of the granules I9 at theedges is never a disadvantage and will always accommodate itself to small irregularities of the panels I0 occasioned by lack of uniformity in panel manufacture.

When panels of the character illustrated in Fig. 2 are employed, the grooves I8 clearly simulate the joints between the panels and it is practically impossible, without very close and critical inspection, to observe the location of joints between the constituent panels, thus clearly serving the intended purpose and accomplishing the result of obtaining an accurate uninterrupted simulation of the face of a brick wall. While I have found that the existence of the grooves I8 provides the best appearance of simulated masonry, such grooves I8 are not essential. Thus, I have illustrated in Fig. 3 an embodiment of the invention wherein the grooves I8 have been eliminated, and I have found that material so constructed gives satisfactory results and accomplishes the purpose of successfully simulating the face of a brick wall. It appears, however, that material provided with grooves I8 is to be preferred for two reasons. 'The first of these reasons is that the grooves enhance the simulation of a shadow at a mortar joint. The second reason is the fact that where a cavity exists between abutting panels as above described, there is some slight tendency to give a darkened eifect by reason of the fact that the granules I9 are of such shape that they do not accurately interflt, and therefore small interstices exist between them through which a small measure of darkened appearance of the thermoplastic material within the cavity may be exposed. This latter efiect is very small, however,

and is fully balanced and complemented by the shadow occurring within the narrow grooves I8 which have the granular material ll exposed therein.
