ALFRED SCHNURR, OF SANDUSKY, OHIO.

METAL-REINFORCED CONCRETE VENEER FOR BUILDING CONSTRUCTION.

Specification of Letters Patent.

Patented May 16), 1910.

Application filed February 8, 1909. Serial No. 476,611.

To all whom it may concern:

Be it known that I, ALFRED SOHNURR, a citizen of the United States of America, residing at Sandusky, in the county .of Erie and State of Ohio, have invented certain new and useful Improvements in Metal-Reinforced Concrete Veneer for Building Construction; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to a metal-reinforced concrete veneer for the walls of build- 1ngs.

One object of this invention is to form a side of the wall of a building by a veneer composed of metal-reinforced concrete slabs.

Another object is to form such a joint between the adjacent edges of adjacent slabs as to effectually prevent moisture from passing between the said slabs from the outer sides of the slabs to the inner sides of the slabs.

Another object is to prevent lateral displacement of adjacent slabs independently of each other.

Another object is to support each slab independently of the other slabs.

Another object is to have the metal reinforcement of each slab extend into the tongues of the tongued edges of the said slab to reinforce the said tongues.

Another object is to have the metal reinforcement of each slab extend into those portions of the slab which form the side walls of the grooves formed in the grooved edges of the slab to reinforce the said walls.

Another object is to provide the metal reinforcement of each slab with members or devices instrumental in attaching the said slab to a slab-supporting member of the wall comprising the said slab so that the concrete or'cementitious material of the slab is not injured by any pull or strain placed upon the said slab-attaching members during or upon the attachment of the slab in place.

lVith these objects in view, and to the end of realizing other advantages hereinafter appearing, this invention consists in certain features of construction, and combinations of parts, hereinafter described, pointed out in the claim, and illustrated in the accompanying drawings.

In the said drawings, Figure 1 is a side elevation of a portion of a wall having one of its sides formed by a metal-reinforced concrete veneer embodying my invention. Fig. 2 is a vertical section on line 2--2, Fig. 1, looking in the direction indicated by the arrow. Fig. 3 is a horizontal section on line 33, Fig. 1, looking downwardly. Fig. 4c is a vertical section on line H, Fig. 1, looking in the direction indicated by the arrow. Fig. 5 is a horizontal section on line 5-5, Fig. 1, looking downwardly. Fig. 6 is an edge view of a portion of the metal reinforcement of one of the metal-reinforced concrete slabs. Figs. 2 and 3 are drawn on a larger scale than Fig. 1, and Figs. 4c, 5 and 6 are drawn 011 a larger scale than Figs. 2 and 3.

Referring to the drawings, A indicates vertically arranged or upright joists of a wall of a building which are connected together at one side by boards or bars B which are suitably secured to the uprights A. My improved veneer for forming one of the sides of the said wall is applied at the outer side of the boards or bars B and composed of metal-reinforced concrete slabs G which are attached, preferably removably, to the boards or bars B which therefore constitute the slab-supporting members of the wall.

Fig. 1 shows my improved metal-reinforced concrete veneer formed by superimposed horizontal rows of slabs G which are arranged on edge or vertically. Preferably each slab C is oblong and arranged longitudinally of the row of slabs comprising the said slab, and the slabs of the said row of slabs are arranged in line endwise. Preferably the slabs of each row of adjacent rows of slabs are arranged to break joints with the slabs of the other of the said rows of slabs. Preferably the slabs C are arranged a suitable distance from the outer side of the slabsupporting members B to form an air-space s between the rear side of each slab and the said slabsupporting members. Each slab C is provided at and centrally of its rear side with a shallow chamber 8 to lighten the slab. Each slab C is provided in its bottom edge and centrally between the forward and rear sides of the slab with a groove 10 which extends longitudinally and preferably from end to end of the slab, and the forward por tion of the said edge slopes upwardly and rearwardly as at 12, from the forward side of the slab to the said groove and is arranged above the rear portion of the said edge. Each slab O is provided at its top edge and centrally between the rear and forward sides of the slab with an upwardly projecting tongue 13 which extends longitudinally and preferably from end to end of the slab, and the forward portion of the said edge slopes downwardly and rearwardly, as at 1 1, from the forward side of the slab to the said tongue and is arranged below the rear portion of the said edge. The tongue 13 at the upper edge of each slab of the lower of adjacent rows of slabs engages the groove 10 in the bottom edge of the adjacent slab or slabs in the upper of the said rows. Hence a tongue-and-groove joint is formed between the top edge of each slab in the lower of ad jacent rows of slabs and the adjacent slab or slabs in the upper of the said rows. It will also be observed that the sloping forward portions 12 and 14 of the bottom edge and top edge of the upper slab and lower slab respectively of adjacent superimposed slabs diverge rearwardly toward the tongue-andgroove joint between the said slabs and are spaced vertically at the forward sides of the slabs and form the top wall and bottom wall respectively of a real-wardly enlarged recess 15 next forward of the said tongue-andgroove joint, which recess is filled with mortar D. The rearward divergence of the top wall and bottom wall of the said recess 15 causes the mortar occupying the said recess to be locked in place between the said walls. Each slab C is provided in one of its side edges with a groove 16, and has a tongue 17 at the opposite side edge of the slab. The said tongue 17 and the said groove 16 are arranged centrally between the rear side and forward side of the slab and preferably extend from top to bottom of the slab. The grooved side edge of the slab forward of its groove 16 slopes, as at 18, laterally and inwardly from the forward side of the slab to the groove. The tongued side edge of the slab forward of the tongue 17 slopes, as at 19, laterally and inwardly from the forward side of the slab to the tongue.

The side tongue 17 of one of the adjacent slabs of each row of slabs engages the side groove 16 in the other of the said adjacent slabs, and hence a tongue-and-groove jointis formed between adjacent side edges of adjacent slabs in one and the same row of slabs, and. the sloping portions 18 and 19 of the said side edges diverge real-wardly and form the side walls of a real-wardly enlarged recess 20 formed forward of the said tongueand-groove joint, which recess is filled with mortar E. The rearward divergence of opposite side walls of the said recess 20 causes the mortar occupying the recess to be locked in place bet-ween the said walls.

The metal reinforcement of each slab 0 consists preferably of a sheet of wire netting G which is embedded in the concrete of the slab in the process of making the slab. The embedding of a metal reinforcement in concrete during the manufacture of metal-reinforced concrete objects is too well known in the art to require description in detail in this specification. Suflice it to state that each slab G contains a metal-reinforcement in the form of a sheet of wire netting arranged within the slab centrally between the forward and rear sides of the slabs, which wire netting extends, as at 22, into the tongues of the slab to reinforce the said tongues, and has portions 23 thereof bent and extending into those portions of the slab which form the side walls of the grooves in the grooved edges of the slab to reinforce the said walls. Each slab O is provided with means for attaching it to the slab-supporting members B of the wall comprising the said slab, which means preferably comprise two metal hangers H spaced longitudinally of the slab and embedded in the concrete of the upper portion of the slab and terminating at their lower ends in hooks 7?, which engage with the metal reinforcement of the slab. The said hangers project to and beyond the rear side of the slab into the space 8 and at the said side of the slab have upwardly project-ing arms 24 arranged within the said space and overlapping the outer side of a slab-supporting member B and re spectively provided with a hole 25 for receiving a screw or securing device K employed in attaching the respective hanger to the said slab-supporting member. It will be observed therefore that each slab is supported independently of the adjacent slab or slabs from a slab-supporting member B,having its wire netting or metal reinforcement G hung upon the hooks 72, of the hangers H of the said slab.

lVhat I claim is A veneer for an upright wall of a building, said veneer comprising horizontal rows of independently supported metal-reinforced concrete slabs, which rows are arranged one above the other, adjacent edges of adjacent slabs of adjacent rows of slabs being provided between the forward and rear sides of the said slabs, the one with a groove and the other with a tongue engaging the said groove to form a tongue-and-groove joint between the said slabs, the forward portion of the top edge of the lower slab of the said adjacent slabs sloping downwardly and rearwardly from the forward side of the slab and arranged below the rear portion of the said edge, the forward portion of the bottom edge of the upper slab of the said adj acent slabs sloping upwardly and rearwardly from the forward side of the slab, and the said forward sloping portions of the said 957,382 &

edges of the said adjacent slabs being spaced vertically and forming rearwardly diverging top and bottom Walls of a recess which extends above and below the rear portions of the said edges, and mortar occupying the said recess.

In testimony whereof, I sign the foregoing specification, in the presence of two Witnesses.

ALFRED SGHNURR.
