"Toa/ZZ whom it may concern,.-

a citizen of the United States, residing at Hagerstown, in the county of Washington and State of Maryland, have invented certain new and useful Improvements inW'indow- Shades, ofwhich the following is a specifica- This invention relates to improvements in window-shades, particularly of that class in which the shade is held at various elevations bya spring-actuated device or devices engagi ing With frictional contact the walls of grooves in the vertical stiles of the window-frame.

#The object of the invention is to Aprovide an improved window-shade of this character i in `which the holding devices are of simple tures of the' invention.

and efficient construction and do not project so as to be in the way of a persons hand or arm resting on the window-sill and which will not rattle when the invention is applied to the window of a car or other vehicle.

i The invention consists of certain constructions and arrangements of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which the invention is illustrated applied to a carwindow; and while the invention is particularly designed for such application it is to be understood that it is also applicable toother Windows. j

In the drawings, Figure l is a face view of awindow with a shade embodying the fea- Fig. 2 is a horizontal sectional view, on a larger scale, of the shadeholding devices with the shade detached therefrom. i Fig. 3 is a similar view illustrating a slightly-different form in which the invention may be embodied. Fig. 4 is a detail perspective view of `the end of one of the holder-rods.

The stiles a ofy the'window-frame are provided in their `opposing faces with vertical grooves h, angular in cross-section, as illustrated in Fig. 2. Within the hem c at the bottom of the flexible and spring-roller shade A or secured in any other suitable manner to said shade is a tube or casing d, whose ends are preferably reduced and are entered into the grooves h with sufficient accuracy to seria No. 129,199. (No modela prevent the said tube from rattling when the window-frame is jarred and yet sufficiently loose to slide up and down in the grooves, which latter thereby serve as guides.` The said tube d contains, as illustrated in Fig. 2, two rods f, pivoted intermediate of their ends on studs or pins g, with their adjacent ends overlapping and pressed apart by an interposed transversely-acting expansion-spring h, which may be contracted to press the said ends of the rods together by means of twoV buttons z', each of which is secured to one end of each rod and works through an aperture in the wall of the tube, so that it may be pressed upon by a persons fingers. The other end of each rod f proj ects out through the end of the tube d and extends in a lateral direction into the correspondinglyturnedportion of the contiguous angular groove, anda boxing j is secured or formed integral withthe said laterally-extending end of each rod and carries rollers 7c, adapted to roll in a slight depression Z in the far Wall of the groove; said rollers normally pressing with sufficient frictional contact against said wall, when the spring 7L is allowed to act, that they will hold the shade at any desired elevation against the action of the shades elevating spring-roller. To release the rollers in order to raise or lower A,the shade from one point Ato another, it is only necessary tograsp the two buttons i between the forenger and thumb and pressthebut-` tons together, which action will rock the rods f in a horizontal direction and Will carry the rollers out of contact with the Wall of the groove. y i

In that form of the invention illustrated in Fig. 3 the angular grooves b' are T-shaped in cross section and there are four rods f, two for eachI groove, as shown. lnprinciple and mode of operation this form of the invention is the same as that illustrated in-Fig. 2.

It will be seen that I have provided a win i dow-shade of the class before referred to which can be easily operated merely by pressing the two buttons 'L' together, said buttons not only being susceptible of ornamentation and producing a pleasing appearance, but being also to all intents and purposes substantially flush with the face of the shade and IOG having no projecting sharp ends liable to in` jure a persons hands or clothes.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination with a Window-frame whose stiles are provided with vertical grooves, and a shade in'said Window-frame, of a tube or casing secured to the shade; rods pivoted intermediate of their ends in said tube and adapted to engage with one end, a wall of said grooves; and a spring acting to press the other ends of said rods apart whereby to rock said rods, as set forth.

2. The combination with a Window-frame whose stiles are provid ed with vertical grooves, and a shade in said window-frame, of a tube or casing secured to said shade; oppositely-extending rods pivoted intermediate of their ends in said tube and carrying at their outer ends rollers adapted for engagement with a wall of said grooves; a transversely-acting spring interposed between the inner ends of said rods whereby to press said ends apart; and buttons with which a persons lingers may engage to press the said in ner ends of the rods together, as and for the purpose set forth.

3. The combination with a window-frame Whose stiles are provided in their opposing faces with vertical grooves angular in crossseetion, and a shade in said window-frame, of a tube or casing secured to the bottom of the shade with its ends mounted to slide in the said grooves; oppositely-extending rods pivoted intermediate of their ends in said tube with their outer ends extending into the grooves and turned in a lateral direction, and with their inner ends overlapping; rollers carried on the outer ends of said rods; an eX pansion-spring interposed between said overlapped inner ends; and buttons secured to said inner ends and working through the wall of lthe tube in position to be grasped by a persons fingers, as and for the purpose set forth.

In testimony whereof I affix my signatur in the presence of two Witnesses.
