Patented Dec. 29, 1931 UNITED STATES PATENT OFFICE FRED J. BURNS, OF SAGINAW, MICHIGAN, ASSIG-NOR TO COLUMBIA MILLS, INCORPO- RATED, OF SAGINAWfMIGHIGAN, A CORPORATION OF NEW YORK 'VIEHVETIAN BLIND TILT RAIL BRACKET Application and March a Thisin-vention relates to Venetian blinds, the essential elements of which consist of a head rail adapted to be secured at the top of a window or the like, and a depending tilt Q rail from which a plurality of horizontally disposed thin slats are adjustably supported, and it is the prime object of the invention to provide a demountable tilt rail bracket which can be very readily attached or removed by in merely loosening one of the securing screws, after which thetilt rail can be readily shifted into or out of position.

Another object is todesign a tilt rail bracket of simple and substantial design, which is economical to manufacture, and which is provided with means for holding the bracket in position regardless of the tightness of the screws.

\ A. still further object is to provide tilt rail 2e brackets which can be easily and quickly detached to permit the removal of the slats and tilt rail as a unit, and which does not necessitate the detaching of the head rail.

The above and other objects will appear 1% as the specification progresses, reference being had to the accompanying drawings in which T have shown the preferred embodiment of my invention, and in which like reference numerals indicate like parts throughout the several views thereof.

In the drawings:

Fig. 1 is a fragmentary front elevation of a Venetian blind embodying my invention.

Fig. 2 is a sectional end view thereof.

Fig. 8 is an enlarged transverse sectional View through the tilt rail showing the bracket in position. I

Fig. 4c is a plan View of the bracket.

Referring now more particularly to the drawings,'the numeral 5 indicates the head rail which is secured in position in the conventional manner, demountable brackets 6 are secured to the head rail by means of screws 7, and a tilt rail 8 is mounted in these brackets, said brackets being formed as clearly shown in Figs. 3 and 4 of the drawings. Pintles 9. are provided in the ends of the tilt rail and are adapted to be mounted in the openings 10 provided in the brackets, to the end that the tilt rail may be pivotally mount- Salli 1931. Serial 1T0. 519,441.

being bifurcated, the open slot 13 being of 1 a width to accommodate the body of a screw member 7, a closed slot 14 is provided near the front end of the bracket, and is of a width substantially the same as the slot 13, the inner end however opening into an enlarged section 15, and is of a size to permit the passage of the head of a conventional screw such as used to secure these brackets in position.

Raised sections 16 are provided on opposite sides of the slot intermediate its length, and

' are formed by pressing the metal when the bracket is being shaped, these sections serving to prevent the bracket working forwardly and becoming detached even if the screws are slightly loose, as the weight of the blind proper is against the underside of the heads of the securing screws.

in practice, the brackets are first spotted on the tilt rail, the screws are then placed in proper position with the head of the front screw ahead of the raised sections 16, now to remove the brackets and tilt rail as a unit, the front screws are turned back (merely one or two turns), the brackets are then slid for- .then with the bracket held against the bottom of the tilt rail, it is moved rearwardly until the screws engage the closed ends of the slots,

then by use of a screw driver the screws are turned tight, but in the event this is forgotten no harm will result, as the bracket will still remain in position.

nee

This construction eliminates the use of a screw driver for inserting and removing the rear screw each time the tilt raii is removed, and which is awkward and unhandy due to the slats and other parts of the blind, the front screw, however, is more accessible, and can be readily tightened or loosened as occasion demands.

From the foregoing description it will be obvious that I have perfected a very simple, practical and inexpensive tilt rail bracket for use with Venetian blinds.

What I claim is:

1. In aVenetian blind, in combination with a fined support, brackets secured thereto and adapted to support a tilt rail, slots provided in the head of said bracket and adapted to accommodate a screw shank, an enlarged section in one of said slots and of a size to permit the passage of a screw head, and a raised portion intermediate the length of the slot to prevent the shifting of said bracket with relation to the screw.

2. In a Venetian blind, the combination with a fixed support, brackets adapted to support a tilt rail, means for securing said brackets in position, slots in said brackets and adapted to accommodate said securing means and to permit removal thereof when said brackets have been shifted to predetermined position, and means intennediate the length of the slots to prevent accidental displacement of said brackets.

In testimony whereof, I hereunto afix my signature.

FRED J. BURNS.
