EDSON S. TAYLOR, OF COLDWATER, MICHIGAN.

ATTACHMENT FOR WINDOW-SHADES.

Specification of Letters Patent.l

Application filed December 22, 1909.

Patented Nov. 22. 1910.

seriai No. 534,511.

To all whom t may concern.'

Be it known that I, EDsoN S. TAYLOR, a citizen of the United States, residing at Coldwater, in the county of Branch and State of Michigan, have invented certain new and useful Improvements in Attachments for VVindow-Shades; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in attachments for window shades having for an object to provide a device which will permit the shade to be moved vertically without interfering with the roller mechanism.

A further object of my invention is to provide a guide-way wherein the window shade may be moved vertically upward or downward.

A still further object is to provide a device which will hold the window shade at a predetermined point along the guide-way.

A further object is to provide a device which will permit of ventilation through the top of the window by positioning the shade at a point below the opening in the window.

A still further object is to provide a device which may be employed not only with window shades but with awnings and the like used on the exterior of buildings.

These and other objects will be hereinafter referred to and more particularly pointed out in the claims.

In the drawings forming a part of this application, Figure 1 is a front elevation of a window having` a shade therefor showing my device as applied to use with said shade. Fig. 2 is a transverse sectional view of the construction shown in Fig. 1. Fig. 3 is a detail plan view of the member used for raising and lowering the roller on which the shade is adapted to be wound. Fig. 4 is a longitudinal sectional view of the member shown in Fig. 3. Fig. 5 is a transverse sectional view of the member shown in Fig. 3, and, Fig. 6 is a detail fragmentary view partly in section showing the guide-way for the bracket supporting the shade roller.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 and 2 are the usual side frames of a window casing, while 3 and 4: are the bottom and top frames respectively, 5 and 6 being the lower and upper sash respectively of the window.

A usual or preferred form of shade 7 is shown wound upon the usual form of roller 8 supported in the usual or preferred form of brackets 9, said brackets being designed to carry the roller 8 vertically upward or downward along a channel formed in the guide-way members 10, one of said guidemembers extending vertically along the frames 1 and 2 adjacent the sashes 5 and 6, said guide members being formed by bending the unsecured portion of a strip of metal throughout its length downwardly toward the secured portion thereof.

A cord 11 or the like is secured to one of the brackets 9 in order to manually move said brackets along the channel of the guide members 10.

A wire 12 or the like has each of its terminals secured to the brackets 9 and extends around a pair of pulleys 13 secured on the frame 4t and in alinement with the guide members 10. The length of said wire 12 is adapted to coil or uncoil upon a cylinder 14, said cylinder being rotatably mounted in a housing 15 formed in sections, said housing being secured by means of screws 16 or the like passing through the ears 17 and into the frame 4.

In order to cause the cylinder 14: to rotate in the housing 15 and thus coil and uncoil the wire 12, said cylinder is mounted on a stem 2O carried by the inner section of said housing, a spring 1S being positioned in' the hollow portion of said cylinder, one end of which is secured to the housing 15, while the other is engaged with a lateral extension in the cylinder which may be termed an inner cylinder 19. That end of the spring engaged withthe housing is provided with a lateral lug 22 positioned in an opening in the outer section of the housing and a pair of pivotally mounted dogs 21 carried by said inner cylinder are adapted to register in notches of said stem 20, when the latter is used to wind or unwind the spring 18 on the inner cylinder 19.

The housing 15 being located at about the longitudinal center of the window, the amount of tension exerted on the wire 12 will be the same at all times. When it is desired to move the window shade upward or downward, it is only necessary to pull on the cord 11 which will,.as is obvious, cause the wire 12 to rotate onv the cylinder 14, and in so'doing, cause one of the dogs 21 to pass out of engagement with its corresponding notch on theV pin 20, thus Vcoiling or uncoiling the spring 18, as may be the case and when the desired point is reached for positioning the shade, the cord l1 is released, whereupon one of the dogs 21'registers in a pin 2O and thus holds the cyltion being the same employed for rolling or unrolling a window shade on its roller.

n It will be appreciated that the shade may be positioned at any point between the frames 3 and 4t without interfering with the mechanismrused'to roll the shade upon its roller and it will furthermore be appreciated that light and ventilation may enter the top as well asthe bottom of the window when employing my device.

It 1s obvious that my device may be employed with awnings or the like, the only requisite being that the working parts contained in the housing 15 must be made proportionately strong enough to stand the strain.-

My device being soreadily and simply constructed, it may be installed without much additional cost.

. What I claim isz-f 1. The combination with a shade roller,

l brackets therefor slidably mounted in window frames, wires secured to said brackets and pulleys in alinement with said brackets, over which said wiresV extend; of a sectional housing mounted above and about centrally of said shade roller, said housing Vcontaining a cylinder, about which said wires are wound, an extension forming substantially an inner cylinder, a spring within said first referred to cylinder and encompassing said inner cylinder, said spring having an end thereof in engagement with said extension and the other end in engagement with the housing, a notched pin extending from one section of said housing, and means within the inner cylinder adapted to engage the notches of said scribed.

' 2. The combination with a shade roller, brackets therefor slidably mounted in Window' frames, wires secured to said brackets and pulleys in alinement with said brackets, over which said wires extend; of a housing formed in sections, on section being provided with an inner lateral stem, a cylinder rotatably mounted on said stem about which said wires are adapted to wind, said cylinder being provided with a spaced apart portion to form substantially an inner cylinder, a spring mounted in the spaced portion around said cylinder and having one end in engagement therewith, the opposite end of said spring being engaged with said housing, and means carried by the inner cylinder adapted to engage notches in said stem, for the purpose described.

8. The combination with a shade roller, brackets therefor slidably mounted in window frames, wires secured to said brackets and pulleys in alinement with said brackets, over which said wires extend; of a housing formed in sections, one section being provided with an inner lateral stem having notches therein and the other with a small opening in the face thereof, a cylinder rotatably mounted on said stem, about which said wires are adapted to wind, said cylinder being provided with a spaced apart portion to form substantially an inner cylinder, a spring mounted in the spaced portion around said inner cylinder and having one end in engagement therewith, the opposite end of said spring being provided with a laterally extending lug, said lug being inserted within the opening in the section of said housing, and a pair of dogs pivotally mounted to said inner cylinder and adapted to engage the notches in said stem.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
