CORNER-STRIP FOR BUILDINGS.

SPECIFICATION formingpart of Letters Patent No. 593,150, dated November 2, 1897.

Application filed November 20, 1896. -Seriel No. 612,896. (No model.)

1'0 aZZ whom it may concern;

Be it known that I, FRANKLIN Woons, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Corner-Strips for Buildin gs, of which the following is a specification.

The object of my invention is to manufacture a cheap and substantial corner-strip adapted to besecured to the two adjoining walls of a building and to project from the the corner, so as to protect the plaster, as fully described hereinafter.

In the accompanying drawings, Figure lis a perspective view illustrating a corner of a wall, showing my improved corner-strip in position, the upper portion of the figure showing the plaster. Fig. 2 is a transverse sectional view of the walls, showing the cornerstrip in position. Fig. 3 is a side view showing the openings for the plaster. Fig. 4: is a plan view of the blank, showing a method of cutting. Fig. 5 is a view of the cut strip separated. Fig. 6 is a side view of one of the cut strips bent to the proper angle. Fig. 7 is a sectional view on the line 7 '7, Fig. 6. Fig. 8 is a View looking in the direction of the arrow, Fig. 5. Figs. 9 and 10 are views of modifications of the invention.

Referring in the first instance to Figs. 4:-

and 5, which illustrate the preferred method of making the strips, A is a strip of sheet metal, preferably galvanized iron. This strip I cut in two longitudinal sections on the scroll line a: by suitable mechanism, so as to produce two sections B B. (Shown in Fig. 5.) These sections each have projections or wings b b, which are bent to the proper angle, so that the strip can be adapted to a projecting corner. The projections or wings b of one section when out out form spaces 0 in the other section, so that there is no waste, as the metal of the entire strip is utilized; but I may increase the space between the wings when a light corner-strip is required.

The wings I) of each strip alternate with the wings I), one set being preferably bent in one direction and the other set being bent in the opposite direction, as shown in Figs. 6, 7, and 8. If, for instance, the corner is a rightangled corner, then the wings are bent at an angle of forty-five degrees to a liney drawn through the projecting rib a of the strip, as shown in Fig. 7, so that the rib, when the corner-strip is applied to the partition or other wall, will project at the corner, as shown in Fig. l so that the plasterer can work up to the strip at each side.

It will be noticed that the wings are separated by the spaces 0. These spaces are formed in the present instance by the cutting out of the projections or wings of the adjoining strip, where two strips are made from one sheet, as describedabove and as shown in Figs. 4: and 5.

The wings or projections are preferably bent on a line a, Fig. 6, which is some distance from the inner edge of the rib a and is in the present instance at the narrowest point or neck of the wing. By bending the wings at this point Iform a series of openings when the strip is applied to the wall, as in Figs. 1 and 8, through which the plaster extends, so that the plaster at the strip will be interlocked therewith, as clearly shown in Figs. 1, 2, and 3. This prevents the cracking and spreading of the plaster at the point where it joins the strip.

I preferably puncture the projections or wings I) h for the reception of the securingnails, although when the strip is made of light material the wings may be punctured by the nails or by the lather when the strip is placed in position; but I prefer to make the strip of comparatively thick material, so that it will not buckle out of shape when being applied, as it is important that the rib a of the strip should be perfectly straight.

The finished strip can be readily shipped, as one strip will interlock with another in packing, so that a quantity of the material can be packed in a small compass and in such a manner that the strips will not be distorted in handling.

I preferably use galvanized iron, so that the projecting edge will not mark or otherwise disfigure the plaster or paper if the room is papered after plastering.

\Vhile I prefer the form shown in Fig. l, the cutting may be angular, as shown in Fig. 9, or the strips may be cut as shown in Fig. 10.

Iclaim as my invention- 1. As a new article of manufacture a corner-strip having a rib a, wings I), 17 projecting therefrom at intervals, the wings I) bent at an angle to the rib a, and the wings 1) alternating With the Wingsb and bent at an opposite angle to the wings I), said Wings being bent at a point some distance from the rib so as to form interlocking spaces for the plaster in the projecting portion of the corner-strip, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

FRANKLIN O ODS.
