To on whom, it may concern.-

Be it known that I, JOHN F. CANNON, a citizen of the United States, residing at Erick, in the county of Greer and Territory of Oklahoma, have invented certain new and useful Improvements in Adjustable VVindow- Shade-Supporting Means, of which the follow ing is a specification.

This invention consists of improved means for adjustably supporting window shades upon windows or the like.

In the practical embodiment of the invention it is contemplated to mount the windowshade in such away as to permit of raising and lowering the same so that its function as a means for shutting off the light may be performed at either the upper or lower por tion of the window, this being advantageous under certain conditions of service. Ordinarily in the common types of windowshades, when the shade is pulled down to shut off the light at the lower-portion of the window, it will obstruct the upper portion of the window. In the practical use of the present invention the shade may be so adjusted as to permit light to enter the upper portion of the window, while the shade shuts off the light at the lower portion thereof The invention includes, essentially, a novel mechanical means employed for adjusting the position of the shade or mounting the same upon the window-frame or part upon which it is attached.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a perspective view showing the invention applied. to a window. Fig. 2 is a side elevation. Fig. 3 is a front elevation, partly broken away, the shade being removed. Fig. 4 is a detail perspective view of the extensible rod connecting the bracket, the supporting-plate being adjacent thereto. Fig. 5 is a section on the line X X of Fig. 3.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

In the drawings, the numeral 1 designates a window-frame in which are mounted the upper and lower sashes 2. At opposite sides of the window-frame are secured vertical guide-rods 3, said rods beingprovided at the upper and lower extremities thereof with transverse openings, through which supporting extensions 4 of supporting-plates 5 pass. The extensions 4 are horizontally arranged, and the rods 3 are held from accidental displacement from the extensions 4 by means of small spring-mousings 6, arranged to cooperate with the extensions, as very clearly shown in the drawings. Mounted for sliding movement upon the guides 3 are the brackets 7, each bracket standing out from its guiderod and having a shade-roller journaled on the roller 8 mounted therein. Further, each bracket 7 is formed with a tubular guide 9, which receives one of the guide-rods 3, thereby slidably connecting the bracket with such rod. The shade-roller 8 and the shade 10, which is adapted to be wound thereon, is of the common spring type most commonly in use at the present time. The brackets 7 are connected together by extensible means, comprising a rod or member 11, composed of telescopic sections. The provision of the extensible member 11 admits of applying the invention to windows of different widths, this being necessary or very desirable in the practical use of means such as comprised by the present invention.

From the foregoing it will be observed that the shade 10 is adapted to be raised and lowered bodily by reason of the peculiar mounting of the brackets 7 on the guide-rods 3. The means for adjusting the shade includes a supporting-plate 12, located at a point intermediate of the brackets 7 and formed at its lower end with a transverse tube 13, which receives the extensible rod or member 11, connecting the brackets 7. The upper portion of the plate 12 is connected with flexible operating me ans, preferably consisting of a chain, cord, or rope 14, which extends over a pulley 15 at the top of the window-frame centrally of the latter, from the pulley 15 over another pulley 16 at one of the upper corners of the window-frame, the chain then passing or extending downwardly to the bottom of the frame. The chain or member 14 is adapted to be connected with a pin 17 at the lower portion of the frame, so as to hold the shade 10 at a desired adjustment vertically of the frame of the window. The chain or member 14 passes through small guide members 18, located at intervals in the length of the chain and secured in any substantial way to the window-frame In actual use it will be observed that the 12 may be raised so as to carry the windowshade upwardly to a desired point of adjustment thereof To lower the shade, it is only necessary to relieve the pull upon the chain or member 14 and the weight of the shade will pull downwardly on said chain until said shade reaches the desired point of adjustment.

The parts of the invention are very easily detachable from the window-frame, and this l is advantageous in that it admits of displacing the shade whenever the same interferes in any way so far as access to the different 5 portions of the window-frame and its sashes is concerned.

sirable feature thereof. Furthermore, the simplicity of construction and operation of the parts is important in order to conduce to the practicality of mechanism such as employed in carrying out the present invention.

Having thus described the invention, what 1 is claimed as new is- 1.

In testimony whereof I affix my signature in presence of two witnesses.
