919,057, Patented Apr. 20, 1909.



Specification 01 Letters Patent.

Application filed January 4, 1908.

Patented April 20, 1909.

Serial No. 409,316.

To all whom "it may concern:

Be it known that I, CHARLES T. MOORE, a citizen of the United States, residing at Allentown, in the county of Lehigh, State of Pennsylvania, have invented certain new and useful Improvements in Corner-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 corner protectors or in other words to devices for protecting the corners of plastered walls.

At present it is customary to employ wooden strips which are nailed or tacked to the corner of the wall but as these stri s project out from the corner to quite a cegree, they are extremely liable to become knocked from the wall and in fact this is a very frequent occurrence. It has also been customary to employ elements between the laths and the plastering for attaching such strips but this is expensive and the application of such devices to an old wall necessitates removing the plaster from the wall at the corners. As a matter of fact it is not so much the insecurity of the nails used in attaching the present forms of wooden strips to the wall corners that renders the strips hable to displacement as it is the fact that they project out from the corners and are at all times exposed to knocks.

To the best of my knowledge the idea of providing a sheet metal corner protector has never before been thought of but I have found that where such a protector is provided, it will not become displaced unless intentionally removed, for the reason that the sheet metal is of an unappreciable thickness and consequently is substantially flush with the faces forming the corner of the wall.

In the accompanying drawings, Figure 1 is a view in elevation of a corner of a wall showing the ap lication of one of the rotectorsembodie in my invention, and, ig. 2 is a horizontal sectional view.

In the drawings, the wall is indicated by the numeral 5. The protector embodied in my invention is in the form of a sheet metal plate 6 stam ed or bent so as to form twowings 7 whic in the drawings are shown as extending at right angles one with respect to the other but which may extend at other respective angles if desired. The bend in the plate is not an acute one but is of such character that a rounded corner is formed, this corner being indicated by the numeral 8. The lower end edge of the protector is at right angles to the vertical edges thereof and these vertical edges are preferably curved throughout their upper portions as at 9 so that the protector is of less width at and adjacent its u per end than at its lower end. Throughout their extent, the vertical edges of the protector are turned or curved inwardly to a very slight degree as indicated at 10 and in attaching the protector to the corner of a wall, headed tacks or nails 11 are driven through the wings of the protector adjacent the vertical edges thereof and the curved edges are in this manner held tightly against the wall. There is a decided advantage in curving the edges of the wings in the manner stated inasmuch as this revents or obviates the exposure of sharp e ges which would render the device undesirable for use as it would be difficult for a person and especially a lady to pass close to the device without tearing the garments. It is to be understood of course that if desired, the wings may be stamped with an embossed design without detracting in any way whatsoever from the advantages above noted and that-they may be finished in any suitable manner to represent wood graining.

What is claimed is A corner protector for walls comprising a sheet metal shield formed of a strip of metal having its bottom squared with the sides and its top in the form of a point with arcuate sides said shield being bent on a longitudinal meridian line to conform to the angle of the wall and having an inturned peripheral flange extending therearound from one corner of the bottom over the point to the other corner CHARLES T. MOORE.
