To all whom it may concern.'

Be it vknown that l, G-noiion lli-Liann a subject of the King of l-lungary, residing at Daisytown, in the county of llilashington and State of certain new and useful Improvements in Adjustable Vil/Yindoiv-Shade Supports, of which the following is a speciiication.

rlhis invention relates to Window shade supports such as are used in supporting .the usual shade rollers, the invention having more particular' reference to a support having an adjustable finger or projection toreceive the trunnion oi? the shade roller, Whereby shades of slightly varyii'ig Width may be supported The invention has for an object to provide a simple support of this sort provided with means for facilitating adjustment oi the said trunnien-receiving projection.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the folloiih ing` description and accompanying drawing, and to the appended c ms in which the Various novel features of the invention are more particularly set forth.

Fig. 1 of the drawing is a face view sliowing a shade mounted on a Window frame by means of my improved supports.

Fig. 2 is a detail face View one of the supports.

Fig. 3 is a transverse sectional view taken on the line 8 S of Fig. 2.

Fig. l is a longitudinal sectional view taken on the line Ll-ll of Fig. 3.

-Fig. is a like view taken on the line m of Fig. 3.

ln the drawing the reference numeral 10 indicates the usual. frame of a Window. To support the Window shade a pair of braclfets `are provided, one at each side of the window, as Will be understood. Since these brackets are of like construction one 'will be described. The bracket comprises a base in the form of an elongated rectangular plate l2 that fits the windowl frame with its main length horizontally extended, and which is formed 'with a number of apertures 13 to receive screws whereby it is fixed to the Window frame. Formed integral with this bracket, and extending from end to end thereof, is a housing element 15 that is projected from the front face of thebraclet, lthis housing element being formed with a slot 1G extending the length thereof on its llennsylvanim have invented,

lower side to accommodate the adjustable trunion-receivinJT element.

lintending loi 'udlnally throne-'li this limising l5.` and sapported at its ond in the ond Walls of the lil. isi is a screw shaft 1S that has one end projet ed from the housing and provided with in enlarged head l5) for turning purpof l shaft i h is screw supports the trunnion 'receiving element which is here shown in the form of an angular one z i of 1vliich projects downward through tVV Ut ill, in close ad ence to the iso or plate 1&2', while the other arm ill is exis-.ended horizontally forward, and has forward end suitably formed to receie the roller trunnion. The arm 21 here shown formed with upirarifl projec ns enflosing a slot to receive the flat end of the triinnion, and it will be understood that the other trunnion-receiving element Will be formed with an aperture to receive the round trunnion on the other end of the roller.

rlhe member 21 is preferably engaged with the screw shaft 18 to be adjusted along the support by rotation of the shaft, this screvv thread connection between the member 21 and the shaft being preferably displaceable to permit of ready adjustment of the member from end to end of the shaft when desired. To this end the member 21 is formed with a semi-circular groove 25 through which the shaft passes freely, While operative engagement of the member With the shaft is effected by a semi-cylindrical nut element 26. rlhis nut element is formed on opposite sides with flat extensions 27 that lie along the bar 21 and have fixed thereto the pins 28 that project into sockets 29 in the bar, these sockets being formed With enlargements 29 in which are located expansion springs 30 that are coiled around the pins and bear outward on the nut elements to urge the latter to inoperative position. These nut elements are retained in operative position by a substantially semicylindrical member 33 that extends the full length of the housing, Within the latter, and pressed against the extensions 27 on the nut element, being retained against vertical displacement, that is transversely to itself by means of the shoulder parts 34, on the said nut elements, which are straddled by the edges of the member 33. Threaded through the housing 15 are one or more screWs 36 that bear on the member 33 and hold it in position with the nut element engaged with the screw shaft 18, it being understood that these screws do notbind against the member 33 and clamps the latter against the nut element, although they may be caused to do so when itis desired to lock the trunnion-receiving element to the screw shaft. l/Vhen it is desired to adjust the member 2l from end to end of the shaft, the screws 36 are loosened slightly, and the springs push the nut element :2G out of operative engagement with the shaft 1S, permitting the trunnion-receiving member 2l to be moved freely along the shaft.

lFor ordinary adjustment to accommodate the supports to slight variations in width of shade, the screw-shaft is rotated by means of the knob 19.

Having thus described my invention, what l claim as nevi7 and desire to protect by Letters Patent of the United States is as follows:

i. A Window shade bracket comprising a base, a housing thereon, a screw shaft supported by and in said housing, a trunnionreceiving element supported by said shaft and having a circular groove through which said shaft passes freely, a semi-cylindrical nut member supported by the said trunnionreceiving element and normally operatively engaged with said shaft, resilient means urging said nut member to inoperative position, and a movable channeled element in said housing extending substantially the full length thereof retaining the nut member operatively engaged with the shaft.

2. it window shade bracket comprising a base, a housing thereon, a screw shaft supeported by and in said housing, a trunnionreceiving element supported by said shaft and having a circular groove through which said shaft passes freely, a semi-cylindrical nut meniber supported by said trunnion-receiving element and normally operatively engaged with said shaft, resilient means urging said nut member to` .inoperative position. and a moveable channeled element in said housing extending substantially the full length thereof retaining the nut member operatively engaged With the shaft, and screws threaded through said housing and engaged with said channeled element to retain the nut member in operative relation to said shaft.

p In testimony whereof I have affixed my signature.

GEORGE BERoziK.
