This invention relates to an improvement in window shade adjusters, more particularly for adjusting the position of a window shade bodily with respect to a window, whereby the shade may bemoved bodily to differentvertical and angular positions with respect to the window.

The object of the invention is to provide suitable shade effect, while at the same time maintaining proper ventilation at the top and bottom of a window without rattling of the shade. This is accomplished by the bodily adjustment of the shade vertically and angularly relative to the window which leaves ventilating space at the top and bottom, when desired, allowing free circulation of air through the top and bottom of the window into and out of the room for complete and thorough ventilation thereof, without creating an undue disturbance due to the shaking and rattling of a shade as was frequently the case heretofore. By providing proper ventilation for the room, by letting fresh air in at the bottom of the window and foul air and gases out at the top, proper ventilation is obtained which will materially improve living conditions for a large number of people. Furthermore, this ventilator and noiseless shade will'allow users thereof to sleep peacefully although they may have been awakened heretofore almost every night by noisy window shade equipment. By adjusting the shade to different bodily positions relative to the window, it is useful for various other purposes, such as an awning, a ventilator, a light reflector, etc.

Another feature of the present invention is its use to prevent the shade from rolling up at the top and getting out of reach, as frequently occurs with shades of the type used heretofore, and it also serves to hold the shade against blowing through the open window out of its proper normal position.

In carrying out these objects of the invention, the shade is supported by balance weights which are enclosed in channels fastened to opposite sides of the window frame. In addition to the balance weights, a pair of arms is provided to position the shade bodily with respect to the window and to adjust it to different positions, which arms are connected with a support for the shade and have provision for detachable and adjustable connection with the channels.

A preferred embodiment of the present invention is illustrated in the accompanying drawings, in which:

55 Fig. l is a front elevation of the shade adjuster applied to a window;

Fig. 2 is a vertical sectional view therethrough;

Fig. 3 is a top plan view of a window showing the shade in a different position with respect thereto;

Fig. 4 is an enlarged plan View of the holder and arm adjuster;

Fig. 5 is a front elevation thereof;

Fig. 6 is an enlarged view of the guide and weight supporting the carrier.

In the preferred embodiment of the invention illustrated in the accompanying drawings, the window frame is designated W, and has secured to the inner side thereof a pair of channels I, which extend vertically along the inner side thereof, and each of these channels is sectional with the sections telescoped so as to fit windows of different sizes. F

The shade is designated generally by the numeral 2, and may be of the spring-type having pintles 3 at the opposite ends thereof, which are received in brackets i of a shade carrier 5, which is also made in two sections telescopically connected together and which extends transversely ofthe window. The carrier 5 has cords 6, secured to opposite ends thereof for supportingthe same, and the shade carried thereby, which cords 9 extend over guides I at the top of the channels I, thence downwardly into the channels, and having counter-weights 8, attached to the lower ends thereof, or the cords may extend through openings in the counter-weights and then upwardly for attachment to the channels or frame at the opposite side, allowing the counter-weights to Work in loops of the cords, in order to have less movement of the counterweights vertically in the channels.

The carrier 5 has sockets 9 formed therein, and receiving the inturned ends II] of arms II which are used to adjust the shade to different positions with respect to the window. The arms II are formed of spring metal normally tending to spread apart, in order to bear against the inner sides of the window frame. Each arm II has its opposite end formed in a reversed bend I2, which serves as a hand-hold for adjusting the arms and shade, and this portion l2 also serves to hold the window curtains and drapes in place when thewindow is open. The extreme end I3 of the arm is formed to enter any one of a series of holes I4, formed in the inner side of the channel I, in order to hold the arm in a desired position.

By grasping the portions I2 of the arms, the shade may be moved bodily up or down, as desired, with respect to the window, which upward movement is assisted by the counter-Weights 8 on the cords 6, and in Fig. 1 the shade is shown in the position where it allows the window to be openat top and bottom for complete ventilation of the room. When the shade is moved up or down to the desired position, the ends I3 of the arms II are inserted into holes I4 in the channels, in order to hold the shade in this position.

In Fig. 1, the shade is fiat against the window in which position it serves merely as a shade, but

shade it should be evident from Figs. 2 and 3, that it may be adjusted to other positions to serve as an awning, a light reflector, draft protector, or it may be moved to one side or other of the window, so as to allow light to come into the room by one side of the window from which the shade is moved, while the shade covers the other side only, as shown in Fig. 3, and may serve to reflect light to the opposite side. In that position, only one arm II need be attached to its adjacent channel, while the other arm may hang free and the shade will then stand out at an angle to the window for the purpose described. I

As shown more particularly in Fig. 2, the shade extends laterally from the window with its upper edge spaced therefrom, so as to serve as an awning, or the like, or if lowered to the bottom of the window, it will serve as a draft protector, but in either event the shade is held forwardly away from the window by the arms I I, which are attached to the carrier 5 and which serve to swing the shade forwardly from the window on the cords 6.

In the different adjusted positions of the shade, particularly as represented in Fig. 2, the free edge of the shade opposite the roller 2, should be fastened to the channels I, in order to hold the shade in place and toprevent rattling or blowing thereof by the wind. This is accomplished in this form of the invention by the provision of pins or rods I5, which are shaped to enter the holes I4, if desired, or to press against the inner sides of the channels in order to hold the free edge of the shade in place by friction. The pins or rods I5 are spring-pressed in order .to hold them in an extended position normally.

By the provision of inside awnings for the room, rather than outside awnings, a very large percentages of fires will be prevented which have resulted heretofore from dropping lighted cigarettes or matches on the awnings. At the same time accidents resulting from putting up or taking down or adjusting awnings will be eliminated. The adjustment of the shade to prevent a view into the room from the outside, may be made without disturbing the ventilation and lighting of the room, so as to let in light and air from the outside and yet excluding vision into the room.
