UNITED STATES PATENT OFFICE- CURTAIN SUPPORT.

Application filed March 20, 1924. Serial No. 700,515.

This invention relates generally to supports for window curtains, more especially to supports constructed wholly of metal and consisting of mounting brackets adapted to be secured at opposite sides of a window frame, and a member, from which the curtains are hung, in the form of a bar or rod with laterally-bentor bowed ends arranged to detachably engage the mounting brackets aforesaid.

My invention has for its main object the provision in a-curtain support of the kind referred to, of a simple form of interlock construction that will rigidly hold the bar or rod member normally against displacement relative to the mounting brackets, and yet permit its ready and quick attachment to, or detachment from the brackets when hang- .ing or removing the curtains.

Other objects and attendant advantages of this invention will be readily apparent from the detailed description which follows, its scope being clearly defined by the appended claims. V

In the drawings, Fig. I is a perspective View showing in complete assemblage a curtain support conveniently embodying my invention.

Fig. II is a view of the support assemblag in cross section and on a larger scale to show the details of the interlock between the curtain rod and the mounting brackets to better advantage.

Fig. III is an illustration similar to Fig. II showing an alternative form of the in vention. v

Fig. IV shows another modification of which this invention is capable.

Fig. V is a perspective view of a mounting bracket modified for use with a curtain rod of circular or rounded cross section;

Fig. VI, a fragmentary view of the round rod adapted to be used with the mounting bracket of Fig. V; and

Fig. VII, a face view of one of the rod ends. I i

A curtain support typical of my invention comprises, with reference first to Figs. I, II and III of the drawings, a pair of mounting brackets 1 adapted tobe secured at opposite sides of a window frame to sustain the rod or bar 10 (upon which the curtain is'to be hung) through engagement with its laterally bent or bowed ends.

.Confining attention for the time being to r the mounting brackets 1,-these are exact duplicates of one another, each being formed from an elongated blank of stout'sheet metal with its central portion offset or raised asat 2 relative to the plane of its ends 3. The ends 3 are pierced as indicated at at for passage of screws or other convenient securing means 5. The ofiset or raised portion 2 of the bracket 1 is punched or otherwise provided with elongated apertures or slots 6, 7 that are aligned along the longitudinal medial of said bracket and comparatively closely spaced as seen to the best advantage in Fig. II.

In the instance under present consideration, the rod 10 is shown as formed of relatively thin sheet metal fashioned, after approved practice, to channel formation with opposite longitudinal edgesretroverted as indicated at 11, the stiffening thus afforded rendering said rod amply rigid against sidewise fieXure. If lengthwise adjustability should be desired, the rod 10 may be made in two parts or sections 10", 10 coupled in telescopic relation over a portion of their lengths as indicated at 12 in F I. -The end of each laterally-bent extremity ofthe rod 10 is notched approximately centrally of its end as at 13, the top edge notched adjacent the end as at 14c, and the lower edge cut away as at 15 thereby. defining an upturned hook 16, a lug 17 immediately below and in line with said hook and a shoulder 18 beneathsaid lug. The notch 1 1 forming the bight of the hook 16 is purposely given the acute angle profile shown to enable tilting ofthe rod in accordance with the dotted lines in FigII, suchprovision facilitating insertion of the hook into said aperture 6 of the mounting bracket 1. The lug 17 has its lower edge, sloped as indicated at 19 with the result that it readily finds its way into. the aperture 7 of the mounting bracket 1 when the rod 10 is swung downward after the hook 16 is inserted in the In the alternative form shown in Fig TV the mounting bracket 1 has but sing e elongated longitudinal slot or aperture 6 designed to receive the book 16 of the rod 10, the lug 17 of the previous form being entirely dispensed with in this instance through omission of the end notch 13, while the sloping edge 19 and the shoulder 18 preserved to function in the capacity afore described. i

Fig. TV shows another modification, the hook 16 being in this case turned downwardly. The lug 1? underlies the hook 16 as before but here its upper edg instead of the lower edge, is sloped (in view of the reversed position of the hook to a. et or ease entry of the lug into the aperture 7, While it is to be noted the upper apertinc or slot 6 is made sufiiciently large to per t the hook 16 to be initially entered an die rod 10 manipulated to bring the lug 17 into register With the lower aperture or slot 7. The effectiveness of the last described construction, it will be obvious, is on a direct par with the others. in each" of the three instances thus far considered, a bar or red of solid rectanglar construction may of course, if it should be preferred, be substituted in place of the channeled type shown.

In Figs. V, VI and V11, 1 have illustrated my invention as embodied in a curtain support involving the use of a rod 10 havinga rounded or circular cross section. The profile configuration of the rod end will be recognized from Fig. V1 as identical to that characterizing the structure of Fig. H, the upturned hook, the associated lug, and the cooperating shoulder being here identified respectively by the

numerals

16, 17 and 18 previously employed. By reason of the rounded cross-sectional configuration of the rod 10 in this instance, a slight alteration is required in the shape of the hook and lug receiving apertures 6, 7 in the offset 2 of the mounting bracket 1. In accord With this requirement, said apertures 6, 7 are made substantially semicircular in form to receive the hook 1.6 and the lug 17 with a comparatively close fit. lfdesired to ob tain the advantage of lightness, a tubular rod may obviously be used in place of the solid bar described.

Having thus described my invention, 1 claim:

1. In a curtain support of the type debed, a mounting bracket having a raised ,sl portion provided with a transverse ire, and a rod having laterally-bent each said end being formed with a for engaging through the apertru'e in bracket and an aligned rigid- I lug, said lug being notchedout at the lower part to anord a supporting sh 1i forabutment with the outer face of the mounting bracket, and said hook and notclu i out part being, respectively, provided with opposedly inclined faces to facilitate i sertion of the rod end into the mounting bracket.

2. in curtain support of the type described, a mounting bracket having a raised central portion provided With a transverse opening; and rod having a laterally-bent end formed with an upturned hook notched out of the upper edge thereof, the bight of said hooks being of acute-angular profile to permit tilting of the rod in engaging the hook in the aperture of the bracket, and a "jacent aligned rigidity maintaining lug, sa d lug being notched-out at the lower edge to affr d a thrust abutmentfor co-operation with the outer face ofthe aforesaid bracket and having its entry face opposedly inclined relative to the bight aforesaid.

3. In a curtain support of the type de scribed, a mounting bracket having a raised central portion provided with transverse open ngs; in combination with a rod having laterally-bent vends, each such end being forn'ied with a hook and an aligned subjacent lug having a notched-out part, said hook and lug having opposedly inclined entry faces and engaging the individual apertures of the aforesaid bracket with the notched out part abutting the outer face thereof whereby a rigid interlock is effected.

a curtain support of the type described, a bracket having a raised central portion provided with transverse openings; in combination with a rod having latcrally-bent ends, each such end being formed with an integral upturned hook having an acute-angled profile, a lug beneath the hook and a shoulder beneath the lug with an inclined entry face, said hook and lug engaging individual apertures in the brackets, and the shoulder abutting the outer face of said bracket to interlock the hook and supportingly prevent displacement of the rod.

5. In a curtain support of the type described, a mounting bracket formed from an elongated blank of sheet metal with a raised offset, said raised offset being pro vided with a pair of horizontally spaced apertures; in combination with a rod having laterally-bent ends, each such end being formed with an integral upturned hook having an inclined entry face and an aligned subjacent 111g with the lower part notched out to afford a reversely inclined entry face, said hook and lug engaging individually in the apertures of the mounting bracket With the notched-out part abutting the outer face thereof intermediate the ALBERT FOSTER.
