WINDOW-BLIND.

' Specification of l lletters Patent.

Patented May 27. 1913.

' Application filed .Tu i 22 1912, Serial No. 705,281.

To all whom, it may concern Be it known that I, HENRY KRUEGER,'C1t1- zen of the United States; residing at ,Spo- -kane, in the county ofSpokane-and State of lVashingt-on, have invented certain new and useful Improvements in Window.- Blinds, of which the following is a specification, reference being had therein to the accompanying drawing. 1

This invention relates to window blinds of the type commonly known as Venetian blinds, and the principal object of the invention to so construct this blind that-it may be mounted outside the window but operated from the inside,v thus making it'u nnec-- essary to raise the window in order to open or close the blind.

Another object of this invention is to provide a blind which will bevery strong and durable so that the different parts of' the blind will operate properly and notvery easily get out of order.

This invention is illustrated in the accompanying drawings, wherein F Figure 1 1s a vertical sectional View through a vwindow frame and blind constructed in accordance with this invention.

Fig. 2 is a fragmentaryview showing the blind closed and the supporting bars of the blind shown in section. Fig3 is a top plan view of the supporting bar for the blind. Fig. 4 is a reduced view of the blind in a raised position. Fig. 5 isa sectional View through the lowenpart. of the blind. Fig. 6 is a View of the device for holding the ad justed ropes in a desired position. Fig. 7 is a side elevation of the bracket and easing which hold the wires upon which the blinds slats of the blind. Fig. 9 is a front eleva run under the desired tensionQ Fig. 8 is a side elevation of the links carried by the tion of the bracket shown in Fig. 7

Referring to the accompanying drawings, it will be seen that this blind is connected with the 'jamb 10 of the window outside of the window sashes, and comprises the upper bar 11which: is secured to the' top of the window jamb-and supports the blind. This bar 11 is provided with longitudinally ex tending grooves 12 and with openings 13 in are mounted,

which pulley wheels 14 and 14 the grooves forming tracks in which i the adjusted lines for the blinds are mounted.

A plate 15 is mounted upon one end of the bar 11, and pulley Wheels are mounted'beneath the plate so that the lines may .pass

' over the pending ear 21, 'the shaft being-mounted between the ear 21 and the body. portion of the bracket. The shaft is provided with a reduced and flattened outer end portion 22 "so' that it may be rotated by means of a inner. end portion 23 is also reduced and flattened as shown in Fig. 9 so that a latch 24 may engage the shaft and thus hold the cable under the desired tension.

Chains 25 are carried by the bar 11 and chains 26 have their upper ends connected with lines 27 which l4so that the angle'of the slats which form part of this blind I 28 is mounted at the lower end of the blind and is connected with thechains 25 and 26 by means of the links 29, the bar being .slidably connected with the cables 16, thus permitting the bar: to be upon the cables When desired.

Slats' 30 are provided with slots 31 in their end portionsthrough which the cables 16 pass, the slats being held in engagement with the cables by means of the wires 32. It should be noted "that the wires are mounted as shown in Fig. 2 with one end portion extending .above the slat and the remaining end portion positioned below the slat,'thus.bracing the slat and making a stronger blind. Links 33 are carried by the slatsand are formed of two sections the eyes 34 which are brought together and connected by a ring 35 which connects them with thechains 25 and 26 as clearly shown in Fig. 1. It will, therefore, be readily seen that when the line 27 is drawn upwardly that the angle of the slats will be changed from that shown in Fig. 1 to that shown in Fig. 4, thus opening the blinds and when the lines 27 are released, the weight of the bar 28 willreturn the slats to the closed position.

maybe regulated. A bar moved vertically Lines 36 have their lower ends passing through openings 37 formed in the bar 28 and secured to the lower face of the bar and their upper ends passed through openings 38 formed in the slats 30 and passed over the pulleys 14 so that by pulling upon the lines 36, the bar 28 may be drawn up wardly upon the cable 16 thus carrying with it the slats 30 and.:raising the blind to the desired height as shown in Fig. 4. When the lines are released, the weight of the bar 28 returns the blind from the position shown in Fig. is mounted upon the side of the window casing and comprises the bracket 39 which is provided with side walls having the diagonal slots 40 cut therein. These slots are sloped toward the window casement toward the upper end of the bracket so that when the lines 36 are drawn in order to raise the blind, the roller 41 may be moved upwardly by means of its handle 42 and thus brought into engagement with the lines so that when the lines are released, the weight of the bar 28 will keep the lines under tension, thus, causing the rollers to securely grip the lines and holding the blind at the desired height. The same means may be used if desired, for. the lines 27 or if desired, any other suitable means may be used for holding the slats at the desired angle.

When using this blind, the bar 11 is secured to the window frame outside of the window sashes and the cables 16 carried by the bar 11, connected with the brackets 19 and placed under a tension. The lines 27- and 36 are led over their pulleys 14 and 14' and through the window casing to the inside of the house. The blind is then in position for use and by drawing upon the lines 36 the height of the blind may be regulated.

' lated by the lines 27.

4 to the lowered position. A clutch After the height of the slats has been regulated, the angle of the slats may be regu- It will thus be seen that there has been provided a blind which is easy to operate and which may be operated from the interior of the house without the necessity of raising the window. This would be very convenient in case it were very cold outside or raining, and not desired to raise the window thus permitting cold or rain to enter the room.v It is, of course, obvious that if desired, the lines 27 and 36 could be brought down the side of the window casement outside the window, so that the blinds could be raised and lowered from a porch outside the windows.

Having thus described my invention, what I claim as new is A blind of the character described comprising a supporting bar, a lower bar, flexible means supporting said lower bar, slats positioned between said supporting bar and said lower bar, links passing above and below each of said slats and having their end portions formed into eyes positioned in alinement, links connecting'the eyes of said first mentioned links with said flexible sup porting means, means for drawing said lower bar upwardly to raise the blind, and means for vertically adjusting certain of said flexible supporting means for adjusting the angle of said slats.

In testimony whereof I hereunto "aflix my signature in presence of two witnesses.

HENRY KRUEGER.
