BRISB'ANE, QUEENSLAND, AUSTRALIA VENETIAN BLIND Appneation mea February 21, i929,

This invention relates to Venetian blinds for use on verandahs and such like places Where it is desired to control light and ventilation, the object being to provide a strong blind which can be supplied at a reasonably low cost, which is strong,

- closed or opened to any desired degree.

In carrying out my invention I provide a number of uprights, each of which carries a number oflevers arranged one above the other and hingedly connected vertically by p a number of'rods.

cured to the outer ends of the levers. Means are provided for operating the blind and seis curing fit in any desired position.

In order that the invention may be better understood, I- will now describe it with the aid of the accompanying drawings, in which Fig. l is a part perspective view (part in section).

, Fig. 2 is a part perspective view with certain parts in different relative positions.

Fig. 3 is a part end view.

Fig. 4 is a part plan. i

The uprights A are arranged in pairs, a -number of levers B, arranged one above the other, being pivotally carried between the uprights forming each pair. The uprights A are secured at the upper and' lower ends. 80 The levers B are, at their inner ends, hingedly connected by vertical rods C, andthe for ward ends carry horizontal vslats D, which are secured thereto by screws or other means.

The'slats D may be half rounded lon the outer edge. 1

The uprights A have rebates E, and, when the blind is closed, the rods C fit neatly into them, thus allowing the levers B lto 11e flat against one another and the nose' of one slat 40 `D to lie on the rear portion of the slat D immediately below it. y

The blind is opened and closed by .the handles F, which are pivoted to, say, the centre l pair of upri hts A and tothe vertical rods C. A grip is provided between the inner ends of the handles F.

The blind is held in any desi edposition .by the pawl H, the end of which engages notches J in rights A and vertical rods C may and which may beV Horizontal slats are se#- dle member' and rod,

instead of pairs, if desired, and the numbers of uprights or pairs of uprights would be accordino to the Width of the blind.

It is a visable to connect the heads of the rods C by a horizontal rail to ensure that they all operate in unison.

The whole or any part of the blind is of Wood and/or metal, as desired, but I find that the former material is suitable for general purposes. The shape and construction of^the various parts may be varied as found desirable and according to the material used and the size of the blind. l Y

Having now particularly ldescribed and ascertained the nature of Imy said invention and in what manner the same is to be performed, I declare that what I claim is 1. An improved Venetian blind consisting of a number of uprights, levers pivoted thereon one above the other, vertical rods hingedly connected to the ends of said levers, horlzontal slats secured on the other ends of said levers, said uprights havingvrebates to receive said vertical rods when said blind is `2. In a Venetian blind including uprights .having downwardly facing notches, levers pivoted to said uprights, one above the other, vertical rods connected to the ends of said levers, and horizontal slats secured on'the other ends of the levers, a handle member pivotally connecting one of the uprights and one of the rods, and a pawl pivotally connected at the -pivotal connection between the hanand engagin said notches to retain the blind in adjuste position.

In testimony whereof I aflix mysignature.
