Specification of Letters Patent.

Application filed. February 19, 1915. Serial No. 9,392.

To all whom it may concern:

Be it known that I, CARL H. J'ABELONSKY, a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Corner and Protectors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to concrete struc-" "tures, and more particularly to a combined reinforcement and protector therefor.

The invention has for its object to provide a curved or angular corner bar or element arranged at the corner of a concrete column, curb, railing, or the like, for reinforcing the corner and preventing chipping or breaking thereof, and means for reliably anchoring the corner member in the concrete structure.

Another object is to provide corner reinforcements and protectors for concrete columns and similar structures and means for connecting or coupling the several reinforcing and protecting elements so as to provide a reinforcement for the entire column or other structure.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter specifically described,

claimed and illustrated in the accompanying drawing, in which:

Figure 1 represents a horizontal sectional view through one corner of a concrete column or similar structure, illustrating the application of the improved corner reinforcement and protector thereto.

Fig. 2 represents a fragmental perspective view of the reinforcing and protecting element removed.

Figs. 3 and 4.- represent fragmental perspective views of various types of concrete structures, illustrating the application of the improved reinforcing and protective elements thereto, and

Fig. 5 represents ahorizontal sectional view through aconcrete column illustrating the coupling means for the reinforcing elements in detail.

Referring to the drawing in detail, wherein similar reference numerals desigconnecting members 11.

natc corresponding parts throughout the several views, the numeral 6 indicates generally one of the reinforcing elements prefcrably of unitary formation and includes an inner or anchoring bar 7 and a corner or reinforcing and protecting bar 8. The inner or anchoring bar 7 may be of any desired shape, in cross section, as for instance it may be circular in cross section, as illustrated in Fig. 1, orrectangular in cross section, as illustrated in Fig. 2. The adjacent surfaces of the bars 7 and 8 are formed with longitudinal ribs 9 and 10 respectively, the ribs being connected by a plurality of spaced The ribs 9 and 10 and'the connecting members 11 constitute a perforate web connecting the anchoring and corner bars 7 and 8 respectively, and designed to assist in firmly anchoring the device in position.

The combined reinforcement and corner protector is embedded in a concrete column or other structure 12, as clearly illustrated in Fig. 1, in such position that the outer curved or angular surface 13 of the corner piece or bar 8 forms a continuation of two of the adjacent surfaces 1 of the column 12. The anchoring bar 7 is embedded in the column 12 and the concrete or other plastic material is molded into therelatively large openings in the web connecting the bars and 8, thus reliably securing the device in position and providing an efficient reinforcement for the column.

As clearly shown in Fig. 2, the connecting members 11 extend transversely between the bars 7 and 8 and are spaced apart a distance considerably greater than the distance between the bars so as not to unnecessarily detract from the inherent strength and rigidity ofthe concrete stnlcture to which the protector is applied. It is further evident that, as the anchoring bar 7 is of substantially the same width as the width of the corner bar 8, the bar 7 rigidly anchors the protector in position and also receives and distributes a large part of the stress incident to blows struck against the corner plate 8, thereby insuring against chipping or cracking of the concrete structure adjacent the corner thereof.

Patented July 23, 1918.

In instances where two or more of the rethe structure and reliably connecting andreinforcing the several protecting elements;

What I claim is:

A-corner reinforcement and protector com- Lemme hers extending transversely between the corner enol anchoring bars, integrally connected with the ribs and being spaced apart 15 V a distance considerably greater than the distance between the bars.
