UNITED STATES HENRY H. LAMPERT, OF CHICAGO, ILLINOIS.

SUPPORT AND SPACER FOR REENFORGING BARS.

Application filed December 18, 1928. Serial No. 681,879.

To all whom itmmy concern.

Be it known that I, HENRY H. LAMPERT, a citizen of the United States of America, and a resident of Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Supports and Spacers for Reenforcing Bars, of which the owing is a specification.

This invention relates to the reenforcing means for concrete structures, particularly beams, and the object of the invention is to provide a suitable sup ort and spacer for the reenforcing bars wliereby these may be fixed in position at any desired specified distance apart without inconvenience or making a change in the supporting and spacing means. It is incidentally the purpose of the invention to rovide a construction which may be made in stock lengths and cut to suit any width of beam.

The objects of the invention may be accomplished by the construction shown in the drawings, wherein Figure 1 is a plan view of a reenforcing bar spacer and support, showing one bar in place thereon.

Fig. 2 is a front elevation, partly in section, of the construction shown in Fig. 1.

Fig. 3 is a sectional detail taken along the line 33 of Fig. 1.

Fig. 4 is a front elevation of a somewhat modified construction adapted to sup ort a plurality of rows of vertically spaced horizontal bars.

Fig. 5 is an end elevation, partly in section, of the construction shown in Fig. 4.

Fig. 6 is a per ective view illustrating different forms of c airs or supports for the reenforcing bars.

The construction to which the invention relates consists mainly of a uniformly perforated strip of metal, preferably channel shaped, the perforations being spaced apart about a distance equal to the diameter of a standard reenforcing bar so that these bars may be laid crosswise of the channel stri s at different desired points and still be in position to be secured to the channel bars y wires passing over the reenforcing bars, and through the perforations in the channel bars. In addition, the perforations in the channel bars receive tab-shaped projections of sheet metal supports. These supports may be of various forms, as illustrated in the drawings, but referably as shown in Figs. 1 to 3. The s l ieet metal supports are suitably bent to properly support the channel bars, and the rojecting tabs thereon are bent over into 100 ing engagement with the are.

Referring to the drawings, the U-shaped channel bars 1 are shown as having the uniformly spaced circular perforations 3. The perforations 3 receive the tabs 4, projectlng upwardly from sheet metal supports 5 for the channel bar. The tabs 4 are bent over against the web of the channel bar to secure the supports 5 to the bar. The reenforcing bars 6 are laid over the channel bars crosswise thereof and secured to the same in any desired position by wires passing over the reenforcing bar and throu h the perforations 2. As shown in Fig. 3, t e supports 5 are punched from sheet metal strips without loss of material, as the tabs 4 for one support are cut from the stock of another support, leaving the cut-out spaces 9 therein.

The supports 5 before bein applied to the channel bars are bent into w at is known as Z form, as shown in Fig. 1, so as to substantially resist being accidentally bent toward the channel bar, a common occurrence with some other types of supports and which it is desired to avoid in order to assure that the reenforcements will be placed the proper distance from the bottom of the form. The perforations 3 are staggered, as shown in the drawing, in order to receive the tabs 4 of sheet metal su ports of this 2 form. This arrangement of erforations is also convenient for wiring tiie reenforcin bars 6 to the channel bars in any desired location.

Figs. 4 and 5 illustrate substantially the same construction, except that the sheet metal supports 5 in this case are cut away as at 10 to provide a rest for one of the channel bars 1. With this modification, a plurality of vertically spaced rows of reenforcing bars 6 may be properly supported, the sheet metal supports 5 in this case at times being turned upside down.

Fig. 6 shows various modifications of the sheet metal supports 5 for use in certain classes of work. These modifications are respectively indicated as 11, 12 and 13.

In the use of the construction illustrated, the channel bars 1 and sheet metal supports 5 are secured together before shipment to the place where used. Then, all that the concrete worker need do to lay the reenforcement is to set these on the forms at the gered with respect to the perforations of the required distances apart, and then place adjacent row, sheet meta supports for said upon the'supports the necessary number of channel her, said sheet metal supports being reenforcing bars. bent into 2 form and provided with pro- 6 I claim: 7 jeetions extending through said a ertures A support for reenforeing bars eomprisand bent down against the web of t' e chaning a channel bar, the web of which is pronel bar. vided with rows of perforations, the erfo- Signed at Chicago this 14 day of Dec. 1923.

Certificate of Correction.

It is hereby certified that in Letters Patent No. 1,556,151, granted October 6, 1925, upon the application of Henry H. Lampert, of Chicago, Illinois, for an improvement in Supports and Spacers for Reenforcinga Bars, an error appears 4 requiring correction as follows: In the heading of the rawings the name of the patentee is erroneously printed as H. H. Lambert, Whereas said name should have been printed as H. H. Lam-pert,- and that the said Letters Patent should be read with this correction therein that the same may conform to the record of the 1 case in the Patent Office.
