UNITED STATES PATENT OFFICE vnNn'rmN nmvn Aumt-'1.-Viotori, Pawtucket, a. 1., assignor to gator-aft Venetian Blind Company, Hasloton,
Application much 1c, 1934, Serial so. 115,984
eam. (01. 150-11 T In describing the invention in detail, reference will be had to the accompa y drawing wherein like characters denotelike or corresponding parts throughout the several views, and in which:- p Figure 1 is an'enlarged view of the up r corner of a window, showing the means for. adjusting the tilt of theslats.
Figure 2 is a vertical sectional view through the upperpartoftheblind. 1 Figure 3 is a view ofone of the brackets shown 'in Figure 1. i Figure 4 isa view of the pinion carrying bracket. I x
Figure 5 isan edge view of Figure 4. v v Figure 6 is a 'view showing the means for sup:
porting the pulley bar in a corner of the window' frame.
In the drawing, a portion of a window frame is shown at A and the pulley bar of the blind or shade is shown at ly and is supported in the upper part of the frame byv the brackets, one of which is shown at 2. The tapes or flexible strips of the blind or shade are shown at 3. and the operating cords at I. These cords, pass through the openings l I in the slats I! of the blind, these slats being connected to the cross pieces I! which connect the strips ontapes of each pair of tapes or strips together, as more clearly shown in-Figure 2.
These cords pass into the groove it of the pulley bar and over the pulleys I5 carried by the bar and eirtend downwardly adjacent one side of the window.
A bracket It is fastened inthe upper left hand corner of the window frame and is provided with 'zontal partof the Figure '7 is a section on line "-44 ofFigured.
the perforated cars It whi form bearings for a shaft 20 having a worm 2| thereon and with a pulley ?22 connected to one-end thereof. The cord 23 passes over this Pulley so that by pulling one end ofthe cord, the shaft is rotated in one 5.
' direction and by pulling the other end, the shaft is driven in the other dire'ctionand the two parts 'of this cord pass through the eyes 24 in the hon-.- bracket IS. A second bracket 26- is fastened to one end of the top rail 10 21 and carries the stub shaft 28 which finds a bearing in the hole 29 in the'bracket I8, the shaft carrying a gear 30 which meshes with the worm 2| so that rotation of this worm 2| will rock the top rail 21 in either direction from a horizontal position, inaccordance with the direction of rotation, of the shaft 20, and thus the slats I2 will be tilted in one direction or the other, due to the lifting of one tape ,or strip 3 of each pair and the lowering of the other strip or tape of each pair. 20
It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent. I
It is to be understood that changes may be made in the. construction and-in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim What is claimed is:-
In a Venetian blind including a top rail, a 3 bracket connected to one end of the top rail and having a pinion attached thereto, a second bracket attached to a stationary membe a pair of spaced horizontal arms on the second bracket extending to a point above the first bracket and said. second bracket having a hole therein located below the arms for receiving a part of the first bracket, a shaft journaled in'thearms of the second bracket and having a worm thereon enaging the pinion, a pulley on the shaft, a cord, passing over the pulley and depending therefrom, said second bracket having a horizontally arranged .part connected with its lower end, said part having a pair of spaced holes therein 1 through which the two partsof the cord pass. 7
