PATENT; OFFICE NEW YORK, N. Y., A CORPORATION OF NEW YORK INTERMEDIATE SUPPORT FOR VENETIAN BLIND TILT BAIIS Application filed May 6,

A Venetian blind usually consists of .a head rail adapted to be secured to the top of a window or other opening; and a depending tilt rail pivotally mounted on the head rail and supporting a series of thin slats in spaced apart relation to effect an angular tilting of the tilt rail and slats, together with suitable means for raising the slats and con trolling the tilting.

One of the salient objects of the invention is to design a one piece intermediate support which is pivotally connected to the tilt rail at substantially the center of the cross section or horizontal axis of rotation thereof, so as to ermit free angular tilting of the tilt rail and slat members throu h a complete half turn or 180 degrees, to e 'ect a complete closing of the blind.

A further object is to provide a one piece support of rigid construction, which is economical to manufacture, which can be easily and quickly installed, and which permits the tilt rail being made up of two or more sections, thereby effecting a material saving in cost of the tilt rail.

The above and other objects will appear as the specification progresses, reference being had to the accompanying drawing in which I have shown the preferred embodiment of so my invention, and in which like reference numerals indicate like parts throughout the several views thereof.

In the drawing:

Fi 1 is a front elevation of a Venetian blin mounted in a window casing and showing my improved intermediate support in place thereon.

' Fig. 2 is an enlarged fragmentary front view of the tilt rail i lustrating'my support. Fig. 3 is an enlarged inverted plan view.

Fig. 4 is a section taken on the line 4-4 of Fig. 2, and showing the support and link, the tilt rail being omitted.

Fig. 5.. is a section taken on the line 5-5 of Fig. 3, also with the tilt bar omitted.

In blinds of large size it is necessary to provide one or more intermediate supports on the tilt rail to prevent sagging, and insure" easy and correct operation, this interao mediate support further permits the tilt rail 1931. Serial No. 535,341.

proper being made up of two or more comparatively short pieces of stock, which is-of course an economical advantage, and also minimizes the possibility of warping.

In the drawing, the numeral 5 indicates a window casement, having the head rail 6'secured to the upper end thereof, and brackets 7 serve to hold it securely in position. Depending brackets 8 and 9 respectively are secured to the underside of the head rail, and a tilt rail 10 is pivotally mounted therein by means of pintles 11 which are mounted in,

,being punched to provide a central rib section 15, (see Fig. 3), the metal on the sides of the ribs being bent upwardly to form spaced apart Wings 16, the upper ends 17 of which are bent at right angles, and in a horizontal plane, and are provided with suitable openings to receive conventional wood screws 18 for securing the end of the tilt rail sections thereto, ample bearing is provided for the bottom of the sections, each of the legs 19 being provided with suitable opening for receiving similar wood screws 20 as shown.

A horizontally disposed pin 21 is mounted in these vertically disposed wings at a point exactly in line with the axis of rotation of the tilt rail, and a link 22 is connected thereto, the upper end of said link being shaped to form a hook 23 which is adapted to engage a screw eye 24 which is anchored in the head rail directly above the support.

The means for tilting the mechanism is not shown in the accompanying drawing nor is the means for raising the slats, and it will be understood that these are of the conventional design and form no part of the present invention which is directed to the intermediate support for the tilt bar.

From the foregoing-description it will be obvious that I have perfected a very simple, ractical, uniform and economical one piece intermediate support for the tilt rails o Venetian blinds.

What I claim is 1. A one-piece bracket for connecting the inner ends of Venetian blind tilt rail sections, and comprising a plate, opposed sections punched in the plate intermediate its Width, said sections being bent upwardly and lying in spaced apart relation, the upper ends being bent horizontally to overlap the upper face of the tilt rail, the edge sections of the plate being horizontally disposed and forming wings adapted to be secured to the bottom face of said tilt rail.

2. A one-piece bracket for connecting the inner ends of Venetian blind tilt rail sections, and comprising a plate, opposed sections punched in the plate intermediate its Width, said sections being bent upwardly in spaced apart relation with the upper ends bent to overlap the upper face of the rail, the edges of the plate adprcent to said punched sections forming Wings for engaging the bottom face of the tilt rail, a longitudinally disposed pin mounted in the vertically disposed portion of said sections, and a link pivotally connected to said in and formed with an open jaw for detacha le engagement with a support.

In testimony whereof I hereunto afiix my signature.

FRED J. BURNS.
