IMPROVBD 'WINDOW-Bunn tlge rlgehnle manet tu* in tlgesc tttters @man mit mating @nrt nf its same,

TO ALL WHOM IT MAY CONCERN-z Be it known that we, WILLIAM BELLA'Ins and HENRY DnMoTT, of Atkinson, in the county of Henry, and

in the State of Illinois, havoinvented' certain new andnseful Improvements in Window-Blinds; and do hereby declare that the follovwingis a full, clear, and exact description thereof', reference being had to the aceompanyingdrawings, and to the letters of reference marked thereon.

The nature of' ourinvention consists in having the window-blind {ixed either on the outside or inside of thetvindow-frame, and arranged with loaded tassels a-nd cords to raise the slats and the whole blind, whichever may be desired. To enable others skilled in the art to make and use our invention, we ivill proceed to describe its construction and operation.

In the annexed drawings, forming part of this specification- Figure, 1 represents aninside view of the blind' with the slats down. Figure 2, an outside view of the samewith the slats raised. Figure 3, a plan-view ofthe window-frame., Figure 4, a s'i'de sectional view;` and Y Figure 5, a plan sectional view. The window-blind consists of slats A A and a folding bar, B, at the bottom, which all are hung on some Vsubstantial and lasting material in'grooves on each side of lthe moulding C. This moulding C is represented in the annexed drawings as being screwedion the'ontsideV casings of the vwindow', but can easily be taken o' and placed on' the inside of the window', so that the blinds will answerfor either the outside or insideof a house.

At each end of the folding bar B are cords D D attached, which run through the window-casing at the top of theiwindow, as shown in figs. 3 and 4, and are joined together von the inside of the house with a vloaded tassel, E. Wheny the tassel E, attached to cords D D, is pulled, it raises the folding bar B, and enables the blinds or sla-tsA. A to be raised to 'any height required, theloaded tassel E acting :is a. balance to the blind. The cord 4Iiwhieh is attached to the centre of the edge of each slut, and which also runs through the window-"casing at the top of the window, and attached on the inside of the house to a loaded tassel, G, is to pull the slats A A edgeways, so that if light is wanted i n at the window, it cnn be obtained, Without raising the blind, by merely turning the slats. v

The advantages of this blind over all otliers aremainly in the simplicity oi' its construction, and its cheapness and durability. 1

Having thus fully described our invention, whatwe claim as new, and desire to secure bylLetters Patent, is-

The arrangement of the slats A A and folding barB in casing C, arranged either outside or inside of the window, and operating by means ofthe cords D andF and loaded tassels E and G, substantially as and for thc purposes above set forth. Y

In testimony that we claim the foregoing, we have hereunto set ourhands, this 11th day of April, 1868.

WILLIAM BELLAIRS, HENRY DEMOTT.
