This invention relates in general to plaster terminals or bases such as corner beads or the like.

Oneobject of the invention is to provide a device of this character embodying Wings of expanded metal and so constructed and organized as to cushion and relieve the wings of the'expanded metal and their strands of shocks and strains which tend to break or snap the strands. I

Another object is to provide a device of this character which possesses not only features of general resiliency but WhlCh is also adapted to interlock in a positive and effective manner with the plastic coating and which is of simple and durable construction, reliable and effective in operation and easy and comparatively inexpensive to manufacture. v

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claim, reference being had to the accompanying drawings forming a part of this specification, and in which:

Figure 1 is a fragmentaryperspective View showing the plaster base or terminal embodying the present invention, and

Figure 2 is a view thereof in horizontal section.

Referring to the drawing, wherein for the sake of illustration is shown one embodiment of the invention the numeral 1 designates a broad rounded bod plate of imperforated or unexpanded s eet metal. Diverging wings 2 of expanded metal are also provided and are formed along the outer edges of the connecting portions 3, the connecting portions being in turn integral with the edges of the body plate 1.

As shown in Figure.2, the body plate 1 may be of substantially arcuate form in. cross section. From each edge of this'body portion an inturned section 4 of the connecting portion 3 extends,-the section 4 being bent back under the body plate and lying in close proximity thereto, althou h being slightly spaced therefrom. Beyond the inturned section 4 the connecting portion has reversely bent or outwardly curving sections 5, and it is from these sections 5 of the connecting CORNER BEAD.

portions thatthe wings 2 extend. It is to be noted that the sections of the connecting portions are not only spaced from the body plate 1, but are also spaced from each other. The connecting portions 5 are of unexpended metal and thus may be bent or flexed as shown in the drawings. Moreover, due to their formation and to the clearance between them and the body plate afforded by their spacing, they yield or flex to cushion and absorb shocks and strains to which the wings 2 are subjected. In other words, should either wing 2 be subjected to bending or distorting pressure or shock, it will not be distorted and its strands will not be cracked or broken because the connecting portions can and will flex to relieve the pressure or stress and prevent injury to the strands or meshes of the expended metal.

The device not only has these advantages,

but by virtue of the reverse bending of the sections of the connecting portion pockets P are defined which adapt the device to interlock positively and effectively with the plaster coatings C designated by the dash lines in Figure 2.

From the foregoing it will be seen that a plaster base or terminal is provided which may be easily constructed from a single piece of metal which can and does embody a broad and curved nose or body plate and which utilizes wings of expanded metal in such a novel and effective manner as to impart to the plaster base or terminal extremely desirable shock absorbing and cushioning features. It is to be noted in this connection that the expanded wings are not only relieved of crackin or distorting strains by the resiliency of t e connecting portions, but also that the body plate or nose can take shocks, breaks or strains without distortion due to the resilient support afforded by the cushioning and connecting portions. In addition to these advantages there is the fur- 'wings of expanded well as the body plate, are imperforate metal, and thus are well able to stand the usa e to which the are subjected.

T e invention 0 aimed is:

A device of the character described comprising a broad rounded body plate of substantially arcuate form in cross section and constituted of imperforate metal, diverging metal, and connecting portlons of unexpanded metal integral with the Wings and with the body plate, each connecting portion including an inturned section extending from one margin of the body late beneath the body plate and ositione close up against the under-face 0 the body plate although just slightly spaced therefrom, each connecting (portion also including a reversely bent an curved section between the inturned section and the associated Wing, the connectin portions being spaced from each other w is afforded to ermit the connecting portions to flex and take up shocks and strains, said connecting portions defining pockets adapted to interlock with the plaster, said pockets terminating at the exposed edges of the body plate.

In witness whereof, I hereto aflix my signature.

EDMUND H. JONES.
