WILLIAM B. HOUGH, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO PATENTED DEVICES COMPANY, OF PORTLAND, MAINE, A CORPORATION OF MAINE.

REINFORCED CONCRETE CONSTRUCTION.

To all whom it may concern:

Be it known that 1, WILLIAM B. HoUoH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful. Improvements in Reinforced Concrete Construction, of which the following is a speci iication.

This invention relates to means for spacing reinforcing bars the proper distance from each other and the desired depth within the concrete body being constructed.

While the invention is applicable to various concrete bodies, it is particularly well adapted for reinforcing concrete beams, one of the objects being to provide means arranged to support and space a varying number of reinforcing bars or layers of such bars.

In the accompanying drawings, Figure 1 is a vertical sectional view showing a plurality of reinforcing bars supported and spaced within a mold or form by means embodying my invention. Fig. 2 is a plan view of a portion of the devices employed. Fig. 3 is a fragmental side elevation. Fig. 1 is a detail perspective View of one of the elements. Fig. 5 is a fragmental side elevation illustrating a modified form.

Referring to Fig. 1, the mold or formwork into which the concrete is poured is indithe mold A near the bottom thereof is a baseplate 1 supported and spaced from the bottom of the mold by a series of ll-shaped gage members 2. Pairs of arms 3 extend upwardly from the plate 1, said arms, in the present instance, being formed integral with the legs of the gages 2. In the embodiment herein shown, theplate 1 has a series of staggered openings or slots 1 therein to receive the staggered arms 3 of the gage 2, sald gage having shoulders 5 at the lower ends of the arms 3 upon which the plate 1 rests. The gage 2 and arms 3 may consist of a strip of sheet metal, the shoulders 5 being formed and the arms 3 staggered by cutting away the arms 3 on opposite sides of the gage. The lower row of reinforcing bars B is laid upon the plate l, eaoh bar lying between the arms of one of the gages 2. The other rows of bars B are supported by cross-pieces'o each of which rests upon the row of bars next beneath it and has a plurality of notches 17 Specification of Letters Patent.

1n its upper edge to receive the bars B. The cross-pieces 6' may be of any suitable material, being herein shown as pieces of sheet metal standing edgewise between the pairs of arms To provide room for this, the arms 3 are staggered or positioned at opposite sldes of the strip of metal forming the gage 2, as above explained. The inner ends of the slots 4 in the plate 1 are practically in line, and when the arms are inserted through said slots, they spread apart laterally slightly and the gage tends to assume an inclined position with respect to the plate 1, as indicated in dotted lines in Fig. 2. This gives sufiicient clearance between the arms to admit the cross-pieces 6. Such clearance may, however, be provided in other ways, as by cutting away or notching the inner edges of the arms, as indicated at 8 in Fig. 5. The length of thecross-pieces 6 is preferably substantially the width of the mold A.

As will be seen from Fig. 1, each vertical row of bars B may lie between one of the pairs of arms 3. If desired the upper ends of the arms may be bent to embrace the respective bars in the top row.

The number of horizontal rows of bars B to be used may be varied to suit requirements, it being necessary only to place in position the desired number of cross-plates 6. The device is thus very easily assembled.

The portion of the device shown in Fig. 2, namely the base plate 1 and the gages 2 and arms 3 is a unitary structure, being assembled at the factory and shipped and handled as a unit. This is a desirable feature in practice.

I do not limit myself to the-exact details herein disclosed, as modifications within the scope of the appended claims will occur to those skilled in the art.

I claim as my invention:

1. Reinforced concrete construction com-. prising a base plate having a plurality .of slots therein, a series of gage members supporting said base plate and each having a plurality of arms extending through said slots, a horizontal rowof reinforcing bars resting on .said base plate. each bar lying between and being held from lateral displacement by two of said arms, a cross-piece resting upon said bars and held by said arms against displacement longitudinally of the barsfsaid arms lyin at opposite sides of said cross-piece, an a horizontal row of reinforcing bars supported by said cross-piece.

2. Reinforced-concrete construction comprising a horizontal base, gage members supporting said base,- a plurality of pairs of arms extending upwardly from said base, a horizontal row of reinforcing bars resting on said base and spaced apart by said arms, a transverse plate restingon said row of bars and disposed edgewise, the respective arms of said pairs lying closely along opposite sides of said plate and serving to hold the plate in edgewise position and to prevent displacement of the plate longitudinally of the reinforcing bars, and a second horizontal row of reinforcing bars supported by said transverse plate.

3. Reinforced concrete construction comprising a base plate, a plurality of gage members supportingsaid plate, a plurality of pairs of arms extending upwardly from said plate, a horizontal row of reinforcing bars resting on said plate, and each positioned between two of said arms, a crosspiece extending transversely of said reinforcing bars and standing edgewise between pairs of said arms, said cross-piece resting upon said row of reinforcing bars, and having notches in its upper edge, and a second row of reinforcing bars resting in said notches. y

4. Reinforced concrete construction com prising a base plate having a plurality of pairs of staggered slots therein, a series of gage members supporting said base plate and each having a pair of staggered arms projecting upwardly through one of said pairs of slots, a plurality of horizontal rows of reinforcing bars, said bars lying between pairs of said arms, the lower row of said bars resting on said base plate, and means for supporting and spacing the upper rows of said bars.

5. Reinforced concrete construction comprising a base plate having a plurality of pairs of staggered slots therein, a series of gage members supporting said base plate and each having a pair of staggered arms projecting upwardly through one of said palrs of slots, a plurality of horizontal rows of reinforcing bars, said bars lying between pairs of said arms, the lower row of said bars resting on said base platep-and a plurality of cross-pieces extending transversely to said bars and disposed edgewise between the pairs of said staggered arms, each of said cross-pieces resting upon the row of bars next below and having a series of notches in its upper edge adapted to receive another row of bars.

6. Reinforced concrete construction comprising a base plate having a plurality of pairs of staggered slots therein, gage members supporting said base plate andeach having a pair of staggered arms extending upwardly through one of said pairs of slots, a horizontal row of reinforcing bars resting on said base plate, a transverse plate resting on said row of bars and disposed edgewise between and held by said staggered arms, and a second horizontal row of reinforcing bars supported by said cross plate.

7. Reinforced concrete construction comprising a base plate having a plurality ofpairs of openings therein, gage members supporting said plates and having arms extending upwardly through said openings, 2. horizontal row of reinforcing bars resting on said base plate, a cross plate resting on said horizontal row and extending between pairs of said arms, said arms being cut away to provide clearance for said cross plate, and a second row of reinforcing bars supported by said cross plate.

In testimony whereof I afiix my signature in the presence of two witnesses.

WILLIAM B. HOUGH.
