CORNER-BAR.

Specication of Letters Patent. Application filed .T uly 29, 1912. Serial No. 712,023.

Patented July 1 1913.

To all 'whom t may concern.'

Be it known that I, HUGH J. FIXMER, a

citizen of the United States, residing at Edison Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Corner-Bars, of

`which the following is a specification.

'vide a simple andcheap bar of the kind stated which will presenta durable surface where the wearlis greatest, or shocks mostfrequent, and eectually prevent damage.

The invention also has for its object .to provide simple and improved means for anchoring the bar in the concrete or other plastic material.

In the accompanying drawing forming a part of this specification, Figure 1 is a perspective view of the corner bar constructed in .accordance with theinvention, and Figs. 2 to 5 show diferent applications thereof. Fig. 6 shows a modified form of bar.

Referring specificallyl to the drawing, the corner bar is a metal strip which is angular in cross-section to form two wings 5 and 6 which are arranged at right angles toone another. A plain angle bar of uniform thickness is preferably employed, but if desired, a 'bar may be employed which is tapered toward one of its longitudinal edges as shown in Fig. 6. Within the .angle formed by the wings are anchoring tongues 7 which are vformed by making transverse slits in the wing 6, said slits extending from the edge thereof and terminating at the an le. The slits are in pairs, and the materlal between each pair is bent downward to form a tongue. It will be noted that the. slits of each pair converge in the direction of the angle, in view of which the tongue is given a greater width at its extremity than at its base. By the dove-'tail shape of the tongue, it is firmly embedded in the concrete or other plastic material, and the bar will bel securely anchored therein.

Fig; 2 shows the bar applied to a curb, the bar, by reason of its angular cross-section, covering the corner, and thereby proteeting the same from damage. The bar is embedded in the concrete or other plastic material of which the curb is formed, iush therewith. The ton es 7 are also embedded in the materlal and thus serve to firmly anchor the bar.

Fig. 3 shows the bar applied to concrete pavement expansion joints. The wings 5 are at the top and are showngrooved to prevent slipping.

Fig. 4 shows the bars applied to stair or step treads, and in Fig. 5 is shown a column, door jamb or similar structure having its corners protected by the bars.

The bars can be bent to-any curve on the job, they can be easily and cheaply produced, and they eectually serve the purpos for which they are designed. o,

I claim:

-A corner bar which is angular in crosssection to form two wings arranged at an angle to one another, one of said wings having slits extending from its edge and terminating at the angle, said slits being in pairs, the members o-f said pairs of slits converging in the direction of the angle, and the material between said pairs being bent to form tongues which project from the inner angle of the bar.

A In testimony whereof I affix my signature in presence of two witnesses.
