andfi are plans of the for-med and notched.

strips from which the top members of the fixture frames shown, respectively, in Figs..7,

p 8 and 9, are made v Fixture frames comprised ofpolygonal top and bottom members or elements that are angular in cross; section, and Whose corresponding corners are connected together by angular uprights forming panels that are filled by giasspanes,arelold;

Here tutors the top and bottom: polygonal members haveeach been constructed of separate pieces that constitute its respective sides or faces, and these pieces have been connected together at the corners of the member 1 by miter joints. This method of construetion was renderedtedious by the necesslty of handlin so many separate pieces and required very eXa cting' and careful work 111 the joining of the pieces togetherin order toproduce. a member that Would be regular of outlme and neat of appearance. Production was thus retarded and consequently rendered expensive;

' It is the purpose of my invention to greatly improve and to cheapen the construction and iiietlioclof manufacture of lighting fixtures of the aforesaid style by forming each top, and bottom-member or element of-a s ngle str p of material, such as sheet metal 01 proper gauge and quality and notcln'ng 't-he same spective viewof Fig I been so i0rm'ed,,the flange 4, which may be prior to bending in such awaythat accuracy and regularity of design is assured When the strip is bent into final shape.

Referring to the parts by reference characters,1 designates, generally, the top member and Qthe bottom member of the fixture irame Which,-as illustrated in Fi s. 1 to at, are exagonalm plan. I The member 1 istOrmed from a; strip "of material'that is bent, by suitable means, into angular cross section thereby to eiiect flangesfi and 4:, as shown in theper- L 5. After. the strip has termedthe basefiange, is marked off into Six equal parts, and at the lines of separation be.- tween such parts the flange is notched, as indicatedat 5, and its ends are trimmed to anan 'le corresponding to theinclination of the sides of the notches 5. ot a s1X sided nember, the notches 5 embrace ,a'nd bybending the flange 3 ad]acent the apex of each of the notches 5 untilsthe sides oi said notches are brought together, a perfect hexagonal ."figure .is produced. The above steps are present in the making of eachot the members 1 and 2, but prior to the bending of the flange 3 of the top member, the inner edge portions of the parts of the base flanged between the notches 5 are bent downwardly 'on' the line ac of Fig. 6 thereby to produce the flanges designated 6 in Figs. land 3. The base and upright fianges'of .thebottom member 2 are designated, respectively, 7 and 8..

7 'Where the edgesoi the notches, 5-are brought together, andwhere the ends oiithe stripare engaged with each other, the joints are secured by deposits of solder or like material,

Inthe production I asindicated at 10. 'The solder deposits on" the lower member 2 are designated 11.

and B of the respective'members 1 and2 are connected together by angular uprights 12,- and theseuprights are .iJJQCl 'lZOgGthQI intermediate their ends by ornamental cross mem-f hers 13. [Panes 14 of glass of any, desired color and surface treatment are set Within the p'anels defined by the flanges 6 and 8 and to the member 1' and uprights 12.

The fixtures illustrated in plan in Figs;

The corresponding corners of theiianges 6. I

7, 8 and 9 are identical. in structural respects Withthe' one above described, the parts being desi nated 'b the same reference characters as are used to indicate the corresponding ele- It is apparent from the foregoing description that my invention provides a very sub stantial construction, and one that is accurate of outline and neat of appearance; and by the method provided by the invention the manufacture of the lantern frame, in various polygonal shapes, is greatly expedited and cheapened over'prevailing methods.

l'laving thus described my invention, What I claim is 1. In a fixture frame of the class set forth, an open frame-like polygonal member consisting of a base flange made up of a plurality of parts arranged in endwise abutting relation and an upstanding peripheral flange and a flange depending from the inner edge of the base flange, sections of the peripheral flange being integral with and common to at least two parts of the base flange and connecting said parts together in the aforesaid abutting relation, a second similarly shaped frame member spaced below the former member, and uprights connecting the corresponding corners of the frame members.

2. In a flxtureframe of the class set forth, a top polygonal member, a bottom open frame-like )ol onal member consistin of a.

base flange made up of a plurality of parts arranged in endwise abutting relation and an upstanding peripheral flange, sections of the peripheral flange being integral With and common to at least two parts of the base flange and connecting saidparts together in the aforesaid abutting relation, and uprights connecting the corresponding corners of the top and bottom members. I r

In a fixture frame of the class set forth, a one-piece open frame-like polygonal member having an upstanding peripheral flange and a flange depending from its inner edge, said member inwardly of its peripheral flange being notched at points spaced apartabout the member and having the opposed edges of thenotches in abuttin relation a second i similarly shaped frame member spaced below the former member, and uprights connecting the corners of the second frame member to the corresponding corners of the depending flange of the first mentioned member.

4. In a fixture frameof the class set forth, a top polygonal member, a bottom open frame-like polygonal member havingan upfil) standing peripheral flange, said member being notched inwardly of said flange at points spaced apart throughout its length and the opposed edges of the notches being in abutting relation, and uprights connecting the corners of the peripheral flange of the bottominember to the corresponding corners of the top member.

In testin'iony"whereof, Ihereunto afliX my signature.
