Specification of Letters Patent.

Patented May 3o, i913.

Application filed March 12, 1910. .Serial No. 548,826.

To aZ/ whom z't may concern."

Be it known that I, WILLIAM H. OBniRNn, a citizen of the United States, residing at Pauls Valley, in the county of Garvin and State of Oklahoma, have invented certain new and useful Improvements in Interlock` ing Concrete Panels, of which the following is a full, clear, and exact description.

This invention relates to improvements 1n the construction of concrete Walls and the novel elements of which the Wall is-composed as hereinafter set forth and claimed.

The `novel construction of the panels of my invention enables the construction of a Wall very quickly, accurately and strongly by Workmen of no especial skill. It enables theconstrnction of Walls the faces of Which are composedI of snch panels in close interlockedrelation,"the flanges of superposed panels engaging and fitting the'lgrooves of the subadjacent panels. It enables the construction of Walls with the" outstanding flanges of the panels in facial contact With separated spaces which may be filled with concrete. lt enables the construction of Walls wherein the two faces of the Walls are separated from each other or Aont of Contact and bridged by locking keys providing an intervening ,space which may be illed with concrete, the keys constituting division partitions providing separate spaces, all of -Wall rvlsi the intro which 'maybe filledvfith concrete, or. any number thereof, according to the election of the bnilder and 'the reqnirementg of the strength of the Wall.

Referring to the accompanying illustratin my impro e panels ravvings d in several manners rf utilization thereof lin 'tire constructionl of i Mia-Figure l-is sectional ist'rating three characters of be co iw. 2 is a norrzontal sect-iena 'i 2-2 of ilig. l.

Fig. a side elevation showing l the locking key and spacer elements of the 5 Wall projecting above the concrete panels to receive superposed or abutting panels. 9 is a detail oit' two of the panels interlocked together Without intervening locking spacer l elements, Where it is desiredl to form a Wall composed of the panels in Contact Without intervening spaces to be filled With concrete.'

Referring particularly to Fig. of the drawing, which illustrates one of my improved panels, the reference numeralV 1 designates the panel which is provided with a series of outstanding facial flanges l1a which are undercut, as illustrated by the dotted line 13, and which diverge from the opposite edges of the panel to relatively Wide waists 1lb at the middle line of the panel.A Inter vening the several flanges 11 are grooves.11 having relatively Wide mouths opening. at l opposite edges of the panel and converging 1 to constricted waists 1lc at the middle line of the panel. The area of the constricted Waists 11 of each groove isv substantially' equal to the area of each end of each of the flanges lla, 'facial flanges of one panel are interlocked i with those of another like panel, as shown in F ig. 9 of the drawing, the'langes of each panel enter the grooves of the other only to the middle line of each anel, leaving one- .half the length oi? the anges exposed for connection of additional abutting panels, whereby a structure composed solely of said panels facing eacli other land interlocked with each other, as sliovvn'in Fig. 9, may be' 5 constructed. The proportions of the flanges andintervening grooves are important, be-

canse to successfully construct a Wall in the `marmer just stated, it is essential that onehall' the length of the flanges be exposed for Y, connection of abutting panels so that the flanges of .the latter accurately interlock, leaving no looseness. would allow relative movement between the panels, and, tl e ivoire, the construeu 'tile facial of vvliielz are interlocked tact, as shown in. Fig. .o

jacent opposed panels, and the Wall caribe -tbu's built Without .looking or tying the pan- Fig.

so that vvlienv the outstanding 'sind suoli looseness Wall composed of panels panel will be connected to and lockedto ad;

els together otherwise than by interlocking' with those of another (as lshown in Fig. 9)'

the narrow locking keys 31 shown in'Fig. 6`

may be employed torengage the grooves 11 of the opposed panels, as shown by the narrowest wall illustrated in Fig. 1. vThese elements B1 are of the same form and-"proportions as the facial flanges 11a, that is to say, they diverge 'from their ends to a relatively wide' waist, and the ends thereof are of substantially the same area as the constrieted Waists 11c of the grooves 11, so that they will enter said grooves only teI lthe waist-line thereof, and thus leave one-half the length of the keys 31 exposed to engage abutting panels, just as shown in Fig. 9 with respect. to the exposed length of the flanges 115. The locking elements 31 have flanges which engage in the grooves of opposed panels, as

shown in Fig. 1, and these elements may be disposed 'in alternate grooves, leaving the intermediate ones to be filled lwith concrete as illustrated by 37 in Fig. 1.

constitute the inner and outer faces of the wall shall be separated a distance frorneach other to provide greater spaces to be filled with concrete, wherea Vparticularly strong wall is desired, locking keys 7 having flanges 9 beveled, as at 8,and diverging from their' ends to the'waist-linethereof to engage the .walls of the groove 11 are used. These keys 7 have spacer webs'40 which span the l space between the inner and outer'faces of the wall as shown in Fig. 1. The proportion of the flanges 9 of this element 'are the same" as with respect to the flanges of the element 31, and the facial flanges 11iL ofthe panels, that is to say, the ends thereof are of substantially the same area as the constricted Waists of the grooves 11, and the diverging edges thereof lfit against the walls of the grooves, so that when utilized' to lock together .the opposed panels of the wall struc- ',ure, said flanges enter only to the middle or waist-line of the grooves ofthe panels, leaving one-half :the'length ,of the elements 7 exposed for the connection ofabutting panels,.-

` as clearly illustrated in Fig. 8.

ln Fig. 1 is illustrated a wall in whiclf'tlie face panels are interlocked together and separated from each other' by the elements 7.

A space Vis thus left between the panels con# stituting the inner' and outer faces lof the wall which may be filled with concrete 29, Fig. 1, and it is obvious, as shown in said figure, that the concrete may be filled in at desired intervals only, or the entire inter- 'the' spacers 7 may be provided with vperfovening space maybe filled with concrete,

as shown in Fig. 3, depending upon the strength of wall desired. It is obvious that the contour of the panels may vary, depending upon the character straight branch. ln Fig. 3 is illustrated a reservoir wall constructed according to my invention inwhich the panels of the exterior face of the wall are convex andvthose of the interior face concave. Where thel concrete.

is desired to fill the entire intervening space, between the panels, the spacing websl() of rations y10 so that theconcrete in 'ad]acent .divisions may be connected together in af -solid mass throughout the structure. These' perforations also may be utilized for receiving strengthening-wires for the filled in concrete or for receiving and supporting an electrical conduit. Whereit is desired the edges of the panels may be fashioned as shown in Fig. 6 to provide pointing grooves 27 between the panels. Where it is desired that the panels which When walls are constructed employing either the keys 31 or the keys 7 .the panels constituting the faces of the wall are arranged in lapped `joint relationas shown in Figs. 1 and V2, so thatthe facing panels are locked together in a horizontal direction.

1. As an article of manufacture, a con-i 105 panel, the areaf'of the eonstricted fwaists of i the grooves being substantially equal to the area of the end of the flanges so that the outstanding Ifacial flanges of'one panel may be v interloeked with those of another like panel' by entering the grooves of the latter only to 'the middle line o f the panel so as toleav one-half'the len h of the flanges exposed by a structure composed of such an es facing each other may be construct with lapped joints.

2. In a concrete wall structure the' combi- 1. I
