To all y11s/mnt 'it may com-I1. fi

.ii.\.\'. a ultim-not the lr'nited States, and resident ol" St. Louis, Missouri, have 'invent-ed certain new and n; Corner-Heads, of which the folloivingis a specification containing a. full, clear. and exact description, reference being'had to the accompanying` drawings, forming a part hereof. j

My invention relates to impiovements in corner beads.

.The object oiA my inveiition is to construct a bead proper in the form of an opense-.inied tulle and to provide .in connection with the bead proper a pair of .stifening and supportingr wings each having an integral. enlarged head which is embraced by .the head proper so as to be hingedly conneoted with the bead. The wings are constructed of pliant material, which quality, in connection with thehinge referred to,

pern'iitsof an adjustment of the wings relatiif-'e to the bead so that the headA may he applied in a. straight. pliinib line upon an uneven surface.

W ith the above purposes in view my invention consists in certain novel features of construction and arrangement of parts as will he hereinafter more full)v described, pointed out in the claiins and illustrated by the aecoinpanyiiig),r drawings. in whieh Figure 1 is a perspective view of a section of a device en'ibodying i-ny invent-ion; Fig. Q-

' illustrates in sectionall plan my iinproyed corner head as in use; Fig. il is a jwrspective view .of a detachable. cxtenioii lirarket; :in-:l Fig. '-L illustrates in side elevation the. extension bracketas :in use. v

Referring' 'to theaoconipaiiying drawings, in which tin` saine part-s are designated by the saine reference characters in the several views: the bead proper l is a tubular strip of metal, the preferred forni of wliii'h is plaiioazonrox in cross section, c., halt round, and has in its plane side an open Seam 2.

The supportingT wines 3 for the Aoe-ad l are constructed oi' pliant sheet iiietah and each winer has at one ol its loiigitiidiiuii edges a oil ff wliirli is substantially circular in cross section. The body portions ol ear-h of the vines are perforated at intervals, the pcrtoraioiis :3 pciinittin;I` the plaster to lie c eu'ibedded to thc rear of and between 'the wings. At i1;` tcrvals throughout the length :fnl Improvements in 'of each ofthe wings there are holes 6 '-lie it known-that l, Tiionas H. xINsthrough which nailsy or the like may be ili'iren for the securing: of the wings to the' wall. v

In assembling the parts for use the bead l is slipped lengthwise over the (foils 4 of the two supjmrtingA wings, the body portions ol the wings projeetii'ig,r through the open seam 2 of the bead 1. As clearly show n the coils .4. in addition to forming a hinge connection with the bead, serve to reinforce the. bead itself against being indented. Thus the head .is well as the supporting wings may be constructed ol" comparatively light or thin material. -Xn extension bracket i' has adjacent to one. ot' its ends and extended froiii une of the. side margins;l an ontstanding, integral ear 8; and extended from .Y

the end iiiargin-and adjacent tothe oppo-V site side margin is anear 9 which extends at right angles to the first mentioned ear. W itliin the body of the bracket there is an ear 10 which is stamped out of the body of..

the bracket and bent to a position at right angles to the body. j A

In applying the bracketjrefer'ence being.

vhad to Fig. 4 of the drawing, the ear 8 1s .'Lv reason of (he half round shape of the i bea-.l l. as clearly shoivnin Fig. 2, the bead itself forms a rather large siioiilcle against whirh the. end of the plaster may anchor behind the bead. the'slioulder of the plaster having a minimum of feather edge., which is advantageous in Plastering in that vit practically eliminates the cracking olf of. the plaster at the feather edge.l

A decided and distinctadi-'antage of the construction ot .my bead is that `the wings arf.l iniilepeutentllv hinged to the bead, therefore. a wider range of adjustment may be had. The coils J. ol the wings reinforr i the entire length ot the bead itself and tien and i i llr hold the bead, andv'th1-ireby they item1 1:. liability of blows on the head wartung the adjacent plaster.

l. ln device of the class described. a

leo

tubular bead having an open seam Aextending the length of the bead,`a pair of pliant sheet metal wings, each winghaving at one.

fof its side marginsan integral coil'extend- 'ing throughout the iength of the Wing and Y "which' coils fit AWithin the bead and substanltially fili the space tnereim and said Wings 'extending outwardiy through the seam, 'whereby said wings are hingedly connected with the bead and the bead; is reinforced throughout its length by said coils.

2. An adjustable metal corner bead comprising a tubular bead portion having a Yrounded front side and an open slit extending lengthwise of its back side, a pair of complementary sheet metal 'strips each having a rounded beaded edge, Said strips being varranged in said slit with their beaded edges within said tubular bead portionand their opposite edges diverging outward, the bead.

ed edges of said stripsbeing in all` angular positions of said wings in Contact with each other and withthe front and back sides of said tubular bead portion, whereby Asaid strips are hingedly connected to said tubular 'bead portion and serve to stiffen the latter.

3. In a device of the c1asS-described,the

combinationvitha tubular bead and a supporting`wing for the bead, which wing s perforated; at `intervals, of an xtensionf bracket constructed of sheet metal and prof tially :1s shown and for the purposes stated..

In testimony whereof, I have signed my i name to this specification, in presence of two l subscribing Witnesses.'
