NOSING FOR CURB-CORNERS.

Specification of Letters Patent.

Patented Nov. 16, 1909.

Application filed February 4, 1909. Serial No. 475,984.

-T0 all whom it may concern:

, generally provided with some device for protecting them from injury by contact with vehicles, etc.

My invention relates to an improved device for this purpose.

It has been usual to insert at the corner of the curb a protective device made in long strips, the end joints of which are smooth. I find that it is much more satisfactory to provide a dovetail joint between the ends of these strips, thereby affording a more sure and close joint and obviating any irregularity in the line of the curb.. IVhen these devices are made of metal they rapidly wear smooth and slippery. This condition is particularly noticeable when the streets are in a wet oricy condition. I have, therefore, provided a rough tread extending across all or part of my nosing.

The anchora e device generally employed is some sort 0? a web extending the entire length of the stri therewith. I-have ound that a nosing may be produced which is much more easily handled and quite as securely held in position, if the anchorage device is simple and detachable and that it need not be continuous throughout the length of the strip.

Instead of using an especially constructed anchorage device, I use bolts and washers of a standard type which are cheap, eflicient and readily procurable.

In the accompanying drawings I have shown one form of devlceinvolvlng my invention.

Figure 1 is a perspective view of a section ofcurbing protected by my improved nosing. Fig. 2 is a plain view of the washer and usually integral or anchorage late. Fig. 3 is a section of the line 33 0 Fig. 1 taken between anchorage devices.

My nosing consists of a strip A preferably of galvanized iron and preferably curvilinear in section, as shown in Fig. 3. The strips are cut at their ends, so as to engage each other in a dovetail joint B. Throughout the length of the strips are longitudinal grooves and projections C forming a roughened tread-way. At suitable intervals are transverse grooves C to carry off water which would otherwise lodge in the longitudinal grooves. At suitable intervals on the inner side of the strip are provided hollow lugs, or projections D, the lnteriors of which are threaded to engage bolts E of suitable size which extend inwardly through the cement and on which are near their heads anchor plates F to insure a rigid engagement with the cement.

While I have shown the'exterior section' rust.

I claim as my invention:

In a nosing for curb corners, galvanized strips, treads on the strips, dovetail joints between the ends of the strips, hollow lugs on the inner side of the strips, screw threads in the hollow lugs, bolts engaging the threads in the lugs, and se arate circular anchor plates surrounding t e bolts adjacent their heads.
