FILLING-BLOCK FO FIREPROOF CONSTRUCTONS.

Specification of Letters Patent.

Patented Nov. 8, 1 91j).

Application sled April 27, 122s. serieu No. 429,393'.

To all whom it may conce Be it `known that I, IENRY ERICSSON, a citizen of the United States, residing at Chicago, vin the county of Cook and State of Illinois, have invented certain new and useful' Improvements in VFilling-Blocks for F ireproof Constructions, of which the following is a. description.

My invention relates to filling blocks or members formed of concrete or other suitable fire-proof mterinl adapted to serve as or the like, and to receive a suitable filling or bucking `of concrete or similar substance around and between them to hold the blocks in position and avoid the use of forms-as usually employed when' erecting concrete floors.

The object ofmy invention is to provide a cheap and convenient filling block of the kind described, in which the lower face' or base of the blocks shall'meet :lt their edges` may when erected so that the usual forms be dispensed with, and any suitable means may bei-employed to support the blocks in position while the concrete is being pnt in placemid hardening.

n To this end my invention consists in .the novel construction, arrangement, and combination of parts herein shown and de- Scribed,1nd. more particularly pointed out inthe claims. A

In'V the accompanying drawings, wherein like- `or 'similar reference characters indicate` parts; -Flgure 1 ls a like or corresponding a floor in 'which my filling blocks ,are employed teken 'substantially on line 1-1 of Fig. 2. Fio- 2 ls :in

' enlarged section teken substantially on line spaces between the b ocks.

2,-2of Fig. 1. Fig. 3 is a View similar' to` that 'shown in Fi 2, showing :l` slightly modified form of lling block.

In the preferred form shown in the drewings, my improved filling blocks 1 1 are formed to jointly cover the entire space between the floor girders 3 3 or other suitble ortions of the frame ofthe building. The ase 2 of eachl block is `substantially fiat and rectangular in form and somewhat wider `than the remaining portionsv of the blocks so that when a plurality of my blocks are assembled sideby side-as shown in Figs. 2 and 3, the bases 2 will meet along their sides, while the ,upper portion and backs of the blocks are suitably separated to receive the binding or carr lng rods 4 4- in the The sides (3A-6 of the blocks are each prel erably curved transversely of the block and the back of each block which is also preierably-'substantislly rectangular and parallel to the face of the base 2. The sides 6-G of the blocks are preferably formedto receive :i filling ot' concrete between the adjacent blocks to support the blocks upon the rods 4.

In the form shown a` portion substantially midway of the sides (3 .is slightly inclined in the opposite direction to lthe general inclination of the sides so that when, the space beJv tween the blocks is -filled with concrete about the rods 4 the same will form a. binder effectna-lly holding the blocks in position in relution to the rods'. The arrangement shown in 2 of the'drawings is such that if lines 7-'-7 are drawn from the center of' the hackof the blocks to the rods 4 at each of its sides it will pass through substantially-the central portion of this 'oppositely inclined portion of each side of the block, so that the line of resistance from the rods 4-4 toI theV bucks of the block are well within the walls of the blocks and through the -center of this oppositely inclined portion.

From the description above it will be seen 4that the 'cross sectionbf the blocks issubstantially in lthe. form of an isosceles trapezoid, the legs of which curve ill the form of portion of an o. ee lcurve and the groored whic is adjacent to the base.

v In the preferred .construction the margins of the base 2 are preferably inclined slight-ly toward the back of the blocks und when erected the lower edge of the face or base portions of the blocks meet. thereby. leaving l asmall V-sllaped recess at the bottom of each space between the blocks'which is pret-` erebly filled with line concretelor other suitable material after which the filling is placed in the entire space between theA blocks and sufficiently above and about their backs. to suitably embed the nailing strips l9-9 -for'carryi'ng the usual. floor construction. No forms of Iany kind are required as it is only necessary to support the blocks in a suitable manner until the concrete is filled in between and around them and properly set after which obviously the structure is complete.

The filling blocks' my be of Suitable.

What I claim as new, and desire to secure by Letters I atent is:

1`. In a fire 'proof construction, a filling block having a rectangular base and a cross Section substantially in the form of an isos celes trapezoid, the legs of which curve in the form of an ogee curve, and t-he grooved portion of the'curve is adjacent to the base, and reinforcin material embedded in the base of the blocl and pro'jecting through the sides-of the latter at a point intermediate the ends of the grooved portion of the curve and cxtendin to a point overlapping the the base of said block, the reinforcing material offering no obstruction Beyond the sides of the base, whereby the ases of ad 'acent blocks 'may abut.

2. In a re proof construct-ion, a filling .block having a rectangular base and a cross section substantially in the form of an isosucele.S, trapezoid, the legs of which curve in the forifrofan-.ogee curve, and the rooved portion ofthe curve is adjacentto te base, and said legs having corrigations adjacent the upper en'd of the groovedportio'n thereof, and reinforcing material embeddedvin the base' of the block and projecting out- Wardly' beyond the legsv thereof.

3. In a tire proof construction, a p'lnralitv i of filling blocks'eacl'i having `a substantially 4flat rectangular base with legs extending from the vmargins of the base inward and toward the back of the block, a portion of each leg-inclined in the opposite' direction, thereby formin Aa groove'1 .filling material between the blo fillingv` materialat 'a point adjacent ythe grooves in the respective legs and .above the contiguousedges of the base of the blocks,

'a-nd;l reinforcing, material inserted in: each block and projecting through the grooved -portion thereof for connection-with said rod. rugations 2O are'provided .to secure a more.
