FIXTURE MOUNTING non METAL lwrNnow casrNes.

Application filed September 28, 1925. Serial No. 59,014.

This invention has for its object to provide window fixtures such as window-shade roller brackets,y curtain rod brackets and other devices usedy in conjunction with draperies and window-shades, which are .easily and quickly attachable to metal window frames without requiring the use of toggle vor expansion bolts, 'or the tapping of perforations in the window frame for the reception and engagement ofthe shanks of machine screws for'securing such fixtures or devices, and further, tol provide means whereby the said fixtures or devices are permanently rigidly secured in place.

A further object of the'invention is to provide fastening devices for securing such devices or fixtures to metal window frames and the like without necessitatingthe tapping of perforations,to thereby permit fixtures adapted for mounting on wood window-casings and the like to be also mounted on metal frames or casings. i

In the accompanying drawings illustrating fixtures land fastening devices therefor, respectively, embodying the invention:

Heretofore, fixtures have been secured to metal window and door-casings by either boring and tapping yperforations in the latter to receivev and rengage machine-screws pass,- ing -through perforations in the fixtures, or by boring perforations in the casing and insei-ting toggle-bolts or expansion bolts. The first-mentioned method is both slow and ineflicient. because of the thinness of the metal of which the casing is composed, and the second method is also slow and more expensive andproduces a clumsy-looking effect.

My invention comprehends the provision of means integral with the fixture or em bodied ina separate device which isboth cheap and very neat inappearance, a characteristic common to both embodiments being that the attachment of the fixture is very quickly and easily effected and is-both rigid and permanent. i

All such fixtures include base or wall-plates, the latter being indicated at Figs. 1 t0 6 inclusive; by reference numeralQ in Figs. 7

'to 9'4 inclusive, by lreference numeral 3 rin Figs. lO'to 12 inclusive, and by reference numeral 4 inFigs. 13 tof15 inclusive. K

forations in the metal casing and bending;

over the free end portions of said projections to engage ther inner ft'iceoit'the Weill of the casing in which the perlmations are provided, this operation being: generallytermed clinching and the said projections bein therefore, hereinafterte1ined"cl1ncll able. The invention further eomprelends j a certain degree of" flexibility or elasticity in the fastening. device which materially, aids in so attachingr the fixture as' to al'ways cause the base or Wall-plate thereottobear soV firmly upon the casing; as to preventA all relative Inoveinentdbetween the latter andthe tiktureunder the` severest strains or stresses to Wliich the'li'xtures are usually subjected.

The cllncliable projections 6A ofFigsl" to 6" inclusive are integral with the base or Wall-plates-1l of the curtain rod, brackets there illiistrated Eacli tllereofcompizises a tonguehaving a bowed port-ion '7- olifsubstantially` semi-cylindrical contour extending front an edge `of `the plate` l outwardly, beyond the planeet tlie outer Yface of said plate, the portion ofsaid' tongue which is adapted to pass through the perfbrationfof the casing being offset from the end.` of the plate `1 andextending perpendicularly thereto and'beyond the plane ottlie rear face thereof. The projections are impairs. extending` from opposite edges` of. the plate and diametricallyj of the same. Y

Tlie perforations Sinthe' Wallofthe casing` to Whicli'tlie iiitures areV t0.' be secured j are preferably round7 and: of."tarlargfer'diL ameter than tlieV Width offthe projections. Tll'ey are relatively so positioned that. the distance between't-ll'eir centers is greater than tle'distance separatingthe free endportions ofi tle projections and so` that when tile latter are passed "through the said perforations their opposing faces will' contact with they Walls of the respective perforations-least removed ,from cach other. Tlius, the greater portion of tliearea ofieach perorationwvill be exposed to view andtlie access oftthcprd jection' 9fof the. tool'for eli'ctingbendlng or clinching of?` the project-ions.

Thesaid tool comprises a suitable body portion 10 for engagementin the handt ot the` operator and asubstantially V-slia-ped end portion which'A includes the projection 9 extending' substantially perpendicularly to the arm llthereof, the latter anditlie pr,o jction9 extendingatangles,of a-liout fortylive degrees, to the axis othebody-portion 10.

the plateI l is' very rigidlylsecured toi tile casing and is heldin; very llim: andl unyield'- ing" contactftherewith," due r tot` the flexion and spring-interaction of"`the"bow=portions"71' Where the type" of* fixture'V adapt-edt fbi' attachment 'toI vvood-l-casiugs` isi` to be used, the attachment to .tlre'metal-casiirgis effected by' inea-11s ofi elastic sheets-metall plates, each provided Witll` paiirof*l diametricallyop posed clinchableprojections. 'Fliese`-` plates are oftvarious designs adapted"ifor'tleA several types of fixtures. Y

Thus, in Figs; 7 't`o"`9"'incltisive,.tire sheetmetal plate l2"l is providedi Witlt central oblong sltf 13i andE clinclialdl@ projections 14 at* its" upper. anda lower4 edges n'iidvvay` between itsside edges, the' piirorchook 15" of the Wall-plate 2 being adapted' to' project through tHe`- said slot' 13.1` The plate; 2' is provided with a perforation.ateaclr side: of the pin4 or` hlool I5 andtlie-platel12 is provided? with acorrespondingspacedpair of indentations 16' whichA provide conical' p rojections to engage in. said pcrforations and thus accurately position the plate'l2 with respect to the plate 2S Theplate 12is some- Wllat'longertliair-the p'llrte2; so that itsrextreme end'portions mayflx'as tlie projections llfarel clinchedit'o-producethe springlilie ellectl above 4mentioned" to hold" the plate 2 in .very firm contact With the. casing; The plate 12" is very" slightly boivedithrougrout its Vlength by the clincli'ing operation andthe conical :projections thus sok firmlyA engaged in the perforationstof the plate'lns to obiviilte all possibility of disengagement except; by tlieuse of"`exeessivefrne;

TheplatelG-sliownin Figs. l() to 12inclusive is adaptedffrisecuring the conventional" Window-'shade rollerbracket' of Figs. 10 and 11, the base or wall-plate 3 of which comprises a flange of the bracket element and is provided with two perforations in which the conical projections formed by the indentations 18 engage. The plate 16 is longer than the plate 3 and upon clinching its end projections 19 will be slightly flexed, for purposes aforesaid.

In Figs. 13 and 14, I have illustrated the conventional type of window-shade roller adapted to be mounted on opposed side faces of the window casing and which includes the plate 4 provided with perforations for the passage of fastening devices and the central dished portion 2O which is slotted or perforated to receive an end element of a shade-roller, this dished portion being circular. The plate 21 provided with clinchable projections 22 and indentations 23 to engage in the perforations of the plate 4, is provided with a central, circular opening 25 through which the dished portion 2O is adapted to project, the plate 21 being somewhat longer than the plate 4, so that upon clinching the projections 22 it will be slightly flexed as and for' the purposes aforesaid. v

From the foregoing it will be obvious that any kind of a .fixture may be easily and rigidly secured toa metal` casing or trim by means of a plate designed to adapt it for co-operat-ion with the perforations of the fixture ordinarily used for the passage of fastening devices or by providing the wallplate or plates of the fixture' with the integral clinchable projections shown in Figs. 1 to 6 inclusive. l

In so far as the tool above described constitutes a part of the invention, the latter may be expressed as constituting a method as defined in appended claims.
