WINDOW-SHADE FIXTURE.'

Patented oct-30,1906.

Application filed January 5,1906. Serial No. 294.685.

To dll whom it may concern:

Be it known that I, DANIEL HoYT, a citizen'of the Unite(i States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful improve'ments vin Window-Shade Fixtures, of-whieh. the following is a specification, reference being had therein .to the aecon'lpanying drawings. i l

This invention relates tothe class o shadeixtures wherein the shade is mounted -on a spring-aetuated rellerwhieh eonstantl y tends to wind or roll the shade thereon, the shade being held at the bottom by a rigid bar and an attached iixture forced in frictional engagement with, and guided by,`grooves in the casing oi' a window-fram f Curtainfixtures of the type shown'in the l-lall patent, No. 483,490, of September27, 1892, possess the grave disadvantage ol the liability ot' the stick being disengaged i'roin the window-jambs when tilted.I ()n the other hand, eurta'in-iixt-ures ol' the type shown in the Forsyth and Forsyth patent, .\'o. :559,446, oi' May 5, ls'tlt'), possess the advantage of greatly-diminished liability ol'the stiel( being disengaged lroin the guidinggrooves in the window-janxh when it is tilted through careless handling, and thisI is due to the presence of the wings extending on opposite sides pf the irietion-tip; hut this type ol' fixture polt-slesses the disadvantage that when spring oi" the shade-roller is 'not nicely adthe )arts are not in perfect working order the stieli whentiltcd is apt to remain in a posit-ion far removed from the horizontal, due to the fact that the ends oi" the wings simultaneous] y contact with the bottom of the grooves in the opposite jambs of the window and remain stuck in that position. i

The object of my present invention is to devise a fixture which shall combine the advantages of both the Hall and the Forsyth types and shall avoid the disadvantages ofv both. This 1 accomplish by providing the friction-tip with wings which when the stick is tiltedv by careless handlingwill maintain their engagement in the grooves of the windowframe, and thus pre-ent the. stick coming out,` l and which are so construeted and arranged that both will not'simultaneously contact clear] shown in the drawings.

with the oppositev bottom surfaces of the grooves when it is tilted, and so will not prehorizontal osition when it is released.

The pre erred form of the invention 1s clearly illustrated in the accompanying drawelevation, showing the horizontal or holding position oli the iixture.

Referring to the drawings, the windoweasing l is iornied with longitudmally-arranged grooves or guideways 2, the usual shade 3, having a shade-har 4 at the lower end, being mounted lor eotiperation with the windowopening in the easing. y l

The holdingr means ol' the present invention is in duplicate at each end of the shadehar -4 and comprises a sleeve 5, secured Within a here formed in the end oi the shade-bar and held therein by a set-screw 7 engaging the sleeve near its outer end. rlhe opposite or' inner end oi' the sleeve is closed hy a block 8, the relative lengths of the sleeve 5 and bore 6 providing a free space inl rear or beyond the inner end of the Sleevel and A s lank 9 is mounted for movement block 8, the end oi' the stem beyond the block being formed with a head 1], adapted on the forward movement of the stem to contact with the block and limit said movement.

The free and outer en d of the Shank 7 is provided with a friction-head 12, preferably of a size and shape to 'fit within the gui deway 2, the operative or outer faceof said head 'bei ng rough cned, as at 13, or otherwise formed to insure frictional engagement with the bottom of the guideway.
