Application filed 22, 3909.

To all whom it may concern:

Be it known that l, JDHN H. ballroom-L, a

subject of the King of Norwey, residing Salt Lake Cit" in the count? or" Salt Lake v JY and {state at Utah. have invented certain new and useful Improvements in Composite and costly method, as the Work has to be performed from hanging scaffolds after the building has been put up and the slabs are more or less inadequately anchored. Still another method is to build a double facing for the Wall out of slabs and fill in between the slabs with concrete progressively as the Wall goes up, the slabs forming a mold to hold the concrete the Wall goes up. Al

thou 'h differ-in from it in lll'l ortent oarticulars, my invention relates more early to the latter method and it consists in a new method of working and also a new constrdction of Wall. whereby great economy of working is obtained and a true, :1Idl501118 and substantial composite Wall built at the lowest cost and inthe most rapid manner, as will be hereinafter more fully dcscrihed with reference to the drawings. in which,

slabs, which may be of marble, slate, artificial stone, or any other desired material. Each slob formed with anchorage holes in its four edges as follows; holes 1 at the middle of its upper and lower edges, holes 2 in the end edges near the top and holes 3 in the end edges at the bottom. These holes are adapted to cooperate with the braces D and D which are made of strap iron. The plane of the cross section of brace l is vertical and its upper end is adapted to enter the vertical mortar joint between the abutting ends of two adjacent slabs and said upper end is provided with adouble dowel pin 2 one end of which enters a hole 2 in the end edge of one slab, and the other end of which dowel pin enters the correspondhole 2 in the edge of the adjacent slab. The brace D is set inclinedly, or at an acute angle to the slab, and has its foot or lower end adapted to be anchored to an anchor block a. in the concrete filling at a point within the sides or' the filling. The brace D is twisted so that its upper portion is in a vertical plane but its lower end or foot is in 1 horizontal plane. The vertical plane gives il'ness, presents a sharp knife edgeto the llinl concrete and this together with its nciined position, which allows the fallin concrete to strike it at an acute angle and glancing b ew, prevents the concrete from -'ing the slab or falsifying its plane after being set. The brace D is horizontal and its cross sectional plane is horizontal and one end of the same is formed with two upturned lugs 3", 3 and one intermediate downtafzrned lugl. Core of the upturned log 3} looks into the hole 3 in. the lower end edge ofn slab, and the other lug 3 locks into the corresponding hole 3 of the abutting slab in the sonic horizontal series, While the idmvn-turn 'l lug l enters the hole 1 in the middle of he upper horizontal edge of the slab.

D" e t-ends "to and connects with the same block which secures the foot of d brace. fne anchorage block a i is a wooden bloelr of dovetail shape, largest the bottom, t ioroughly saturated with oil so it is non absorbent and will neither expand nor contract from the absorption of Water. These blocks are embedded in the top of each layer of concrete as it 1s land 3 43 .L hi the upper suriace and the foot of Theother'end or the horizontal brace the brace, the wedge and the anchorage block, to fix and hold the slab and braces in true and permanent position while the nex layer of concrete is being filled in.

-The slabs A are set-up, one horizontal layer at a time around the whole building, and form one side of the mold which is to receive the concrete and which slabs become' when the concrete sets a permanently connected wall facing. In order to hold the concrete while being filled in behind these slabs, I employ a horizontally shiftable one side mold plate B, Figs. 1 and 3. .This oneside mold is of my invention and has been covered by me in United States Patent No..

926,269, June 29, 1909. It consists of a metal plate with flanged edges. It is supported on one side of a wall as it is built up by means of downwardly projecting pins ('2 Fig-3, along its lower edge, which pins are inserted in the projecting loops or eyes 1 of wire anchors t which are built in "each layer of concrete L, as the wall goes up, the eyes 7' projecting from the concrete just far enough to receive the pins 22 of the metal. mold and hold it up. The mold plate B is clamped in vertical position and held against one side of the wall {by two or more cant'alivers C fulcrumed to the lower edge of the plate and having each a bearingcfoot c at the lower end that bears against the previously laid layer of wall, and a cam-headed or cranked lever c at the upper end, that locks the mold side and cantaliver together against the wall. This one-side wall mold is supported inthe anchor loops 9* and after the concrete is filled in and tamped between it and the permanent slabs on the other side, the detachable one side mold is loosened by turning its levers 0 and its pins 1) are lifted out of the-supportingcyes r of the wire anchors t and the oneside mold is'adjusted horizontally along the wall a distance nearly equal to its length and is there reclamped and the filling continued ,to further extend the horizontal layer of concrete.

.In order to give greater strength to the wall to prevent settlement and cracking, l embeded a metal reinforcement between each layer of concrete; This reinforcement is shown at E E and consists of two parallel wire cable strands or rods with cross wire connections E. This is made of a width to be fullyembedded in the concrete and after a layer of concrete has been laid and before the braces for the next course of slabs have been set I lay this reinforcement;

longitudinally along the top of each layer and then pack the concrete for the ne t layer on top of the same.

Mode of ope1atz'ng.ln my method of building the composite or faced concrete wall, the basic layer of slabs with a removable mold side forms a mold which is first filled with concrete all around the building and in this concrete are embedded the wire anchors t a short distance below the v top of the layer and also the oil-soaked wooden blocks a which are flush with the upper surface. These blocks are spaced to correspond'with the position of the vertical joints of the slabs. The reinforcing E E is then laid on. A second horizontal course of slabs is next erected on one side above the first course and are held in position by the come sufficiently rigid in their matrix of cement to stand the nailing and erection of the following course of braces.

It'has been common to build a filled and faced wall with double facings in which the facin were reciprocally connected across one to the other. This allows both together to swing in or out and the falling of'concrete on the horizontal cross pieces jars the slabs or blocks and has a tendency to draw them into a distorted position out of plumb. In my invention, it will be seen, that the slabs are held by inclined braces whose feet have an anchorage in the set and solid subjacent layer of. concrete by anchorage blocks embedded in the body of the wall, which gives a rigid, positive and independent support for" the slabs to hold them in place and allows the one side wall mold to be worked on the inner side. The inclination of the braces and their sharp edges in vertical direction also prevents falling concrete from having any disturbing effect upon them and thus preserving the plumb of the slabs after once being set. Each slab, it will be seen, is also anchored on all four of its edges, at two points in the middle in its horizontal edges, and two points at each end.

In setting up the facing slabs or bricks, I first apply to the inner side of the same, next to the concrete, a surface coating of adhesive waterproof material, as shown in Fig. 3; This prevents the moisture from the concrete from penetrating the slabs or bricks and producing efllorescence stains on stable and in aim without seer/2e 8 the outside and also prevents moisture from the weather from passing through to the inside.

With reference to the incorpontion of the longitudinal reinforcing, l would state, that preventing the wall from sagging and cracking if there should be a Weak spot in the foundations, as sometimes happens on made ground. M

ln order that, me valu'eot this construction of wall may be still better understood, 1 would call attention to the fact that the supporting body of the Wallis composed exclusively ofcemcntconcrete in a series oil s perposed layers, which layers are quite rapidly laid one upon the other, progressively upward. When such built up wall has attained a certain'height, its increasing and cumulative Weight is liable .to cause the lower layers, which are not fully set, to

" bulge out or mash down under the superincumbent Weight, so that ordinarily a wall laidin layers would have to wait at regular intervals for the lower layers .to set and harden before loading them with other su per'oosed layers. This involves a great loss at time in building" whichmy wall construction and method of laying is designed to avoid. That is to say, when the layers .oi 'relatiyely sort concrete are alternated with layers oflona'itudinal metal reinforclaid between the layers and embedded eherem, such metal reinforcing with its ladder-lilac cross connections, acts a tension member which holds the entire mass mashing down, bulging out, or getting oiit of plumb, so that construction mayrapidly progress without long intervals of cessation from work for the concrete to set, and thus much valuable time bes'aved, while at the same time the wall when set ture, becomes a very strongly braced and stable wall.

' As a'modification of my invention, 1 may maltea. double faced wall as seen in Fig. --l

where A s are similar slabs anchored by the same method of inclined bracing to anchorage blocks embedded in the top surface of a subjacent layer of concrete. In

this case nse of the shiftable one-side wail mold is dispensed with.

' instead ofusing upright thin slabs for the facing, relay, as a iurther rncdification, use a. cfbliclts, as seen at A in Fig. 5, it being understood that when I use the term slab as racing; material I mean also to in :clnde laminated slabs llkeiirlcks.

V in such and longitudinally-in the horizontal en r-he briclr courses at, suitable netal tiehairy; seerfgg 5 andfi,

and unified in a monolithic strucand form the inclined braces D with hooked ends that embrace the tie bar in the laminated wall. A horizontal brace [D is used on the top of each layer of concrete and the anchorage ends of these braces may be secured either by the wedge and nail heretofore described, on by fins turned onthc ends of the braces and hammered into the wood anchorage blocks. in this case the one-side wall mold B may be used.

In my method of all construction, the concrete is brought to the wall as it rises by an overhead conveycr, such as shown and described in Patent No. 917,331, April (3. 1909, and the workman in ramming the con- ;crete stands on a hanging platform or shelf which is supported by pins or hooks in the eyes '1 of the anchors t and which platform is shifted horizontally along with the oneside wall mold. I

The great advantage of my method is to be found in the reduction of expense for forms and scallolding, the. convenience in operating and the substantial and economic construction of the Va 1. The bracing of the facing slabs obliquely downward into an anchorage in the previously laid ,and set concrete of the subjacent layer "is an important feature of the method, since it gives an individual, solid and invariable anchorage for the slabs. The braces are not liable to be disturbed by the falling; concrete from the conveyer buckets and as the braces and their anchorage blocks are entirely embedded in the middle portion of the wall. the inner face of the wall is free and unob structcd for the working of the one-side wall mold along the same.
