9 Claims.

My invention relates generally to the application of veneer to walls, said. veneer being composedof relatively thin blocks, tiles or bricks and the like, and more particularly to fastening means for-maintaining veneering units in posi- 'tionon a wall before the mortar is applied to the joints of the units.

Certain prior veneer wall constructions have provided means for holding the veneering units on the wall before the mortar is 'applied, but the members which engage the units are easily bent or displaced so as to throw the units out of alignment, with the result that the veneer presents an unsightly appearance after the mortar is applied.

It is therefore an object of the present invention to provide improved veneer fastening means which will positively maintain veneering units in proper position and alignment on a wall.

Another object is to provide improved veneer fastening means which is easily applied to a wall, and which can be applied to a whole section of the wall before the veneering units are applied.

A further object is to provide improved veneer fastening means which requires a minimum of time and material, and in which the veneering units are easily and quickly secured on the wall.

Another object is to provide improved veneer fastening strips adapted for permitting-expansion and contraction thereof without disturbing the means attaching the strips to the wall.

A further object is to provide improved. veneer fastening means to which each veneering unit is easily applied and then individually clamped and interlocked Without danger of chipping or breaking the edges of the units.

A still further object is to embody all of these features in a simple and inexpensive construction which provides for great flexibility in the application of the veneer covering.

These and other objects are attained by the improvements comprising the present invention which may be stated in general terms as including fastening strips adapted to be attached to a wall at intervals, each strip being U-shaped in cross sectionand having a series of projections thereon for securing a plurality of veneering units in spaced relation, the units having grooved opposite surfaces for receiving the projections, the projections at one side of each' unit being preformed to fit in the adjacent groove in the unit when the unit is applied, the projections at the opposite side of each unit being adapted to be bent into interlocking engagement with the ad- 'jacent groove of said unit after said unit is applied, and there being slots in the sides of the fastening strips for receiving and supporting the veneering units in proper alignment.

Similar throughout the several views of the drawing.

In Figs. 1 and 2 is shown a portion of a building wall indicated generally at H] and constructed of siding, which may be tongue and groove siding I I secured to studding in the usual manner. Preferably, theouter surface of the siding II is first covered with some form of insulating material shown at l2 before applying the improved veneer fastening means. I

The veneer wall shown in the drawing and described herein is formed of veneer bricks l3, but other veneering units canbe substituted therefor without departing from the scope of the invention as defined in the appended claims.

The improved veneer fastening means preferably includes the U-shaped or channel-shaped strips l4 having the web 15 and side flanges l6. These strips are preferably formed from sheet metal and m'ay be galvanized or otherwiserust proofed. v

The strips M are applied to the wall preferably in vertically extending rows, as shown in Fig. 1, the rows being preferably horizontally spaced apart a distance less than the length of one of the veneer bricks N to be fastened thereby, so thateach brick will be fastened by two strips as of the shown in Fig. 1.

Each strip I4 is provided with longitudinally spaced projections punched-out of the web l5 and preferably extending from the web in the same direction as the side flanges l6. 'I'heprojections are spaced longitudinally of the strip in such manner that a veneer brick l3 will fit between each pair of projections, and so that the numerals refer to similar parts M bricks after being fitted in the projections will be spaced vertically so as to allow for horizontal mortar joints, as indicated at I1.

. Each brick or veneering unit I3 is provided with grooved opposite surfaces, that is, the upper and lower surfaces of the brick are provided with longitudinal grooves indicated at l8. The lower projection |9 of each pair between which a brick |3 fits is preformed to fit or interlock in the lower groove H! of the brick. In other words, the lower projection l9 ofeach pair has its outer end bent upwardly before the bricks are applied, so that when the bricks are applied one between each pair of projections the outer end 20 of each projection l9 will enter into and interlock with the lower groove |8 of a brick l3.

The alternate projections 2|, that is, the pro-' 'jections which engage the upper surface of the. bricks, are formed substantially at right angles to the web |5 of the strip. Preferably the projections-2| are slightly curved laterally of the strip for a purpose to be hereinafter described.

. Substantially. midway between each pair of

projections

20 and 2| ,the web i5 of each strip is formed or curved outwardly in a substantially spherical portion, as shown at 23in Figs. 2 and 3,

and a hole 24 is provided inthe curved portion 23 through which the nails 25 or other means pass for attaching the strips to the wall. Preferably the holes 24 are somewhat. elongated longitudinally of the strip for a purpose to be hereinafter described.

Preferably each side flange l6 of the strips is provided with slots indicated at 26 laterally adjacent to each pair of projections l9 and 2| for receivin the veneer brick l3 which is fastened by thatpair of projections, and for supporting that brick in alignment with other bricks on the wall. The slots 26 form lugs 28, the upper surfaces 29 of which are preferably at rightangles to the web 15, and substantially in the same plane as and laterally adjacent to the projections I9, so that they act to support a veneer brick |3 in horizontal position. By applying all of the strips 4 to the wall ID in such manner that the surfaces 29 of thelugs are in horizontal alignment, the horizontal alignment of all of the bricks in each course is positively maintained. ,In applying the improved veneer wall construction, the improved fastening strips M are first attached to the. wall in vertical rows by means of nails 25 and the like passing through holes 24 into the siding II, and the upper surfaces 29 of the brick supporting lugs 28 are located in horizontal alignment. The elongated holes 24 provide for slight longitudinal adjustment of the strips as they are being fastened, so as to facilitate alignment of the lugs 28. The curved or spherical portions 23 of the strips provide for maintaining-a positive clinching action between the nail heads and the strips to hold the strips tightly against the wall regardless of. expansion and contraction of the strips after they are in place.

After a relatively large section ofthe wall surface has had the securing strips attached thereto in this manner, the veneer bricks |3 are applied. These bricks are adapted to be inserted one between each-pair of projections l9 and 2| as best shown in Fig.2, and each brick I3 is preferablytilted slightly-as it is inserted between the projections so that its lower groove l9 receives the end 20 of the preformed projection l9. :Aftel the bricks |3 have been inserted in this niannerthey may be slid horizontally in the strips in order to space them horizontally sufflciently to provide for the vertical mortar joints indicated at 30, and in this manner the vertical mortor joints may be slightly. varied to accommodate the bricks to irregularities in the wall.

After the bricks have been thus inserted between the pairs of projections, the upper projection 2| of each pair may be bent downwardly at its outer end into interlocking engagement'with the upper groove I8 of thebri'ck. A special tool may be provided for this purpose such as is shown at 32 in Fig. 5, and has a protuberance 33 on its underside for engaging the projection 2 I, and lateral ears 34 for bearing upwardly upon the lower surfaces 35 of the lugs 28. Preferably, the lower surfaces 35 of lugs 28 are slightly undercut as shown to aid in preventing accidental withdrawal of the tool during the bending operation.

The tool 32 is inserted in a position such as shown in dot-dash lines in Fig. 4, with the protuberance 33 bearingon top of a projection 2| to be bent and the ears 34 extending under the lower surfaces 35 of laterally opposite lugs 28.

By forcing thetool downward to the. full line positio-n, the protuberance 33 bends the projection 2| into interlocking engagement with the upper groove I8 of a veneer brick, as shown.

.Since the projections 2| are slightly curved laterally, the projection grips or clinches the brick at both'sides of the projection instead of at one point only, as might be the case if the-projection were fiat. Also the laterally curved shape of the projection strengthens the same so as to prevent springing back thereof after the bending tool is withdrawn. I I r.

The supporting lugs 28 provide for positively maintaining the veneering units ofeach course in proper alignment on thewall because the bricks are supported on the upper surfaces v of the lugs instead of on the easily bent projections onthe web. Moreover, when the upper projection 2| of each pair is bent into interlocking engagement with the upper grooved surface of each brick, the action of the clamping tool 32 is to force the brick downwardly against the solid supporting lugs 28, so that the alignment of the bricks is not affected. 7 a

Due to the fact that the horizontal spacing of the strips may be varied slightly to fit irregularities in the wall, and that the bricksmay be moved horizonally after being inserted between the. pairs of projections, the. present improved veneer construction provides the same flexibility during construction as is present in the layingup of an ordinary brick wall by a mason.

The veneering bricks or units are easily'applied and interlocked in the improved fastening means without danger of chipping or breaking the edges of the bricks, and the improve d fastening means are simple and inexpensive to manufacture and to install. 3 j I Obviously, the improved fastening strips may be arranged on the wall in invertedposition, or

in horizontal rows instead. of vertical rows without departing from the scope of the invention as defined in the appended claims. 2' 1 V 1.
