BLIND Application led Januaryv 9, 1932. Serial No. 585,643.

It is a further ob]ect of the present invention to provide novel suspending meansfor such blinds which can be quickly applied in 'most convenient marmer to the window frame or other portal.

It is still another object to provide blinds Y or shades of the character described which may be produced at comparatively low cost.

With the above and other objects not specically mentioned in view, my invention comprises the novel construction, combination and arrangement of elements to be hereinafter more fully described, shown and defined in the appended claims.

In the accompanying drawings which form part of this specification and in which similar reference characters denote corresponding parts Fig. 1 is a top plan view of my device;

Fig. 2 is an elevational view thereof;

Fig. 3 is a section seen in the direction of the arrows along line 3-3 of Fig. 2;

Fig. 4L is a similar partial section showing a diilerent position of the shade slats;

Fig. 5 is a view partially in section of the bracketmember shown at the right of Fig. 1

Fig. 6 is a section seen in the direction of the arrows along line 6-6 of Fig. 2;

Fig. 7 is a partial elevational view of a modified form of my invention; and

Fig. 8 is a section seen in the direction of the arrow along line 8-8 of Fig. 7.

Referring to the drawings, 1() denotes the side pieces of a Window frame, door jamb or other portal frame.

Adapted to be mounted at opposite points to the said side pieces are bracket members each of which are constructed of metal or other suitable material and respectively comprise the

plates

11 and 12 which are here shown as rectangular in shape. Extending of laterally from edge of each of said plaies are wings 111 and 121 and respectively which may be provided with holes 13. Extending laterally from

said plates

11 and 12 along the opposite edges as said first named edges arc wings 11`' and l22 respectively. The latter have extending therefrom parallelly respectively to

plates

11 and 12 but in opposite direction thereto the wings l13 and 123. Said last named wings are provided respectively with slots 11 eachA in thesame. relative position on the respective wings 113 and 123 which are alike. The latter named wings are each also provided with a cut out or slot 15.

Rotatably borne between wing 112 and an 65 auxiliary wing 11, which latter is attached to or integrally formed with wing 113, on a spindle 1G, is a pulley 17 located opposite slot 15 of said member.

The blind which is adapted to be supported from said brackets may comprise a block 18 of wood, metal or .other suitable material. At opposite ends headed pins 19 are provided which are adapted to be inserted into the respective slots 14 of 'wing members 113 and 123. The slots 14 slant upwardly from their inner ends so 'that the pins 19 will `not fall out thereof. Also mounted at each end of said block are leaf springs 20 which press against the respective members 113 and 123 80 when block 18 is mounted therebetween and while permitting rotation of said block provide suiicient friction to retain the latter in an position into which it is rotated.

buitably suspended intermediate the ends of said block 18 are loops 21 formed of bands of flexible material such as cloth, webbing or the like. I

A second block member 22 is provided to which the bottoms 21'1 of the respective loops 21 are attached as by nailing or the like.

Extending between the opposite legs 21" of the respective loops 21 are a plurality of cross straps 23 which are regularly spaced from each other in vertical direction. 95 Adapted to be Supported between straps 23 which are at corresponding levels on each loop 21 are the shade members comprising thin slats or boards 24 each of which is shown 00 as rectangular in shape in the present embodiment and which are each provided with lateral slots 25 so spaced from each other as to be concealed by the loops 21.

Manipulating means in the form of a loop 26 of flexible wire or cord whose ends 261 are knotted under block member 22 covered by the respective loop bottoms 211 is provided. The legs 262 of said loop are respectively led through the slots 25 of each slat 24 and through suitable holes 181 (only one of which is shown) in the member 18 whence they are led over the pulley wheel 17 after passing through slot 15 and hang freely along one side of the window frame, door jamb or other portal. When loop 26 is pulled downwardly it raises the blind by pulling the block member 22 and slats 24 into contact with one another until they are closely packed toether above the window or other portal rame. to be lowered.

To conveniently rotate the member 18 and thereby vary the angular position of the slats 24, the following expedient is employed. A flexible member 27 of similar material to loop 26 passes through a suitable opening 28 1n the front leg of a loop 21. It then passes through the slots 25 in slats 24 above opening 28 and around the rear edge of block 18 and is fixed to the latter by passing it through a hole 182 and' knotting it at 30. A second similar member 27.1 passes through the other slots 25 in slats 24 above opening 29 of the other loop 21 and around the front edge of block 18 and is also fixed to the latter in similar manner. Thus pulling member 27 rotates block 18 in one direction and vice versa when member 271 is pulled.

Since loops 21 are attached to member 18, the slats 24 and member 22 are correspondingly rotated.

It is only necessary wlth the device and brackets above described for a vendor to carry a few standard sizes for, if variation from standard is met with in any particular case, he need only remove the pins 19 and springs 20 from the ends of member 18, collapse the shade and saw olf the required amount from each end to obtain the necessary fit Pins 19 and springs 20 are then remounted to the ends of the member 18 and it is used as before.

A variation of the device above described to eliminate the necessity of sawing off the ends may be constructed as follows. In place of member 18, I provide two members 31 which extend from opposite ends of a sleeve 32 and which ma be pushed together or drawn apart in said sleeve. The slats likewise are divided into two members 33 which extend from opposite ends of a sleeve 34. The member 22 is replaced by a member (not shown) similarly constructed as block 31 to be extendible. Thus the blocks and slats Releasing loop 26 permits the blind may be extended or pushed together to meet the requirements of the particular Window or portal frame. The other elements and brackets are the same as before.

In each case the width of the slats 24 should b; so admeasured that at the extreme limit o the slats overlap each other and completely prevent the passage of light in Well known manner.

It is to be noted that the brackets may be attached to the portal frame either as shown by screws or bolts passing through

wings

11 and 12 thereof or by bolts (not shown) passingthrough holes 13 in Wings 111 and 121.

My invention may be modified in many ways without departing from the spirit thereof and I do not wish to be limited to the details shown and described.
