This invention relates to novel shade bracket for window shade rollers and the like,

ventilating shade bracket and more particularlyto a detachable which has for its particular object the provision of a bracket for malntainlng a window shade in position so that it may be moved up and down with the window, preferably the upper window or sash, to provide for prop ventilation at the top of er and convenient thecwindow when the upper sash is lowered, without permitting the shade to blow or flap under the action of air current or wind in such a manner as to mutilate the shade or to injure curtains suspended or hung at theinside of the window, as well as to facilitate window cleaning and the maintenance of the shade in a clean and sanitary condition and avoid the possibility of the shades getting'in a condition of dis'-' repair in undue time;

Another object of this invention is the provision of a shade bracket for supporting win dow shades or the like which shall bemounted directly upon the upper or rearward window sash and which will not interfere with the motion of one sash past the other when it is desired to clean the windows or for any other operation which necessitates the move ment of the sashes up an d down past each other, and which is so constructed that the cont-act of the top rail of the lower sash with the bracket will be cushioned in such a manner as to absorb the shock should the lower sash be unduly raised or the upper sash unduly lowered to open the brackets are in position with or window when the without the shade hung therein, and which will also ob viate the possibility of the shade being dis lodged from the brackets, and particularly at the splndle end of the shade which is usually provided with a. rectangular or other polygonal shaped end in cross section which engages a'rectangular opening in the bracket to cause the spring to function in winding the shade upon the roller 1n the usual manner. I Another ob ect of the invention is to provide a novel form of bracket for supporting shade rollers and the like, tached to the upper sash which will be ac'commodat which may be atof the window and ed in the space be- 1924. Serial No. 716,?22.

tween the parting strip and inner stop of the-frame, so as to permit a shade of extra width to be employed, thereby allowing a minimum of space between the edges of the shade and the sides of the frame of the window, especially in connection with modern window frame construction where the mould ings at the inside of the frame as have heretoround spindle end of the roller and then in serting the rectangular spindle end in the respective brackets, the bracket havlng the rectangular opening being constructed in a novel manner and provided with an entrance slot opening at the rear and adjacent to the sash cord, so that the sash cord will close the mouth of the slot ove'rwhich is provided a top portion or hood designed to guide the rectangular spindle end into the vertical portion of the slot of the bracket but adapted to prevent dislodgement of the roller in an upward direction due to the lower sash striking the roller or otherwise.

A stillfurther'object of the invention is to provide a novel bracket including the bracket properhaving'therectangularbearingopening for the correspondingly shaped spindle end of the shade rollenin which'the spindle engaging portion is offset outwardly'from the main portion of the bracket so that a wider and longershade will be accommodated by the brackets between thesides of the window frame in the space between the parting strip and the innerstop, as heretofore referred to, thus obviating wide openings between the side edges of the curtain or shade and the window frame so that vision into a room is obstructed or prevented from the outside, even at a very sharp angle, owing to the narrow space between the sides of the shade and the sides of the window frame, as 00111 pared with the spaces allowed by shades as heretofore hung. The bracket is so constructed at the slot and opening that the entrance and removal of the rectangular spindle into and from the slot will be facilitated, and may be readily accomplished without inconvenience.

A further important object of this invention is the provision of a two-part bracket for window shades or the like which is adapted to have one of its parts readily removed from a window so that the window panes may be cleaned and so that there will be no obstruction to the movement of one of the sashes past the other, said two-part letachable shade bracket being adapted to maintain the shade on its roller in a position upon the upper window sash so that it may be movable with the window, while a deep offset or curved portion between the main portion of the bracket and the bearii'ig portion which elfset outwardly, permits the shade to track or be accommodated therein it is moved up and down to raise and lower the shade and to wind and unwind the same upon and from the roller without engaging and mutilating the side edges of the shade, and also to serve as a stop to engage the shade slat at the bot tom or thickened portion whereby the end of the shade ill be prevented from running over the roller and unwinding therefrom when once wound thereon and set or adjusted to a proper position with proper spring tension to cause complete winding of the shade upon the roller.

Other and further important objects of the invention will be apparent from the disclosures in the accompanying drawings and the following specifications.

The invention, in a preferred form, is illus trated in the drawings and hereinafter more fully described. 7

In the drawings:

Fig. 1 is an inside elevation of a window with a pair of co-operating window sashes therein, showing the improved bracket of this invention.

Fig. 2 is a fragmentary sectional elevation partly broken away and showing the brackets applied to the upper sash of the window with the shade and its roller mounted therein, the frame being shown in section.

Fig. 3 is a horizontal sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a vertical sectional view taken on the line 44 of Fig.2 and showing the ac tion of the top of the lower sash engaging the roller and brackets or effect of upward force being applied to the roller tending to dislodge the spindle ends from the brackets, which is prevented by the present construction.

Fig. 5 is a dis-assembled perspective view of the two part detachable bracket showing the rectangular spindle engaging end, and

Fig. 6 is a face view of the bracket proper illustrated in Fig. 5 and showing the manner of engaging and disengaging the rectangular spindle end of the roller therewith.

Referring to the drawings in detail, in which like reference characters designate corresponding parts throughout the several views, the numeral 7 indicates a window frame having the usual outer stop 8, control stop or parting strip 9 and inner stop or bead 10, between which the grooves or guide-ways 11 and 12 are provided for the upper and lower sashes l3 and 14 respectively, of the window having the usual window panes. The sash cord is designated at 15, and it is understood that the outer sash is set rearward from the inner or lower sash and provision made for clearance between the same at opposite sides of the parting strip 9 in the usual manner, in connection with window frames having the usual innermouldings or in which such mouldings are provided at the inside wall or where such mouldings or panels are omitted and the same terminate at the inner stop 10, as is well known in modern construction.

As shown in the drawings, the improved detachable ventilating shade bracket of my novel invention is applied directly to the face of the upper sash 13, being applied so that the top edge thereof is in line with the top of the glass or window pane and lower edge of the top part of the upper sash. The bracket is made in two parts, one part consisting of a plate 16 adapted to be fixed to the top windoi sash and held in predetermined position thereon by means of ordinary wood screws or the like. The plate 16 is provided at its top and bottom with bent over lugs or ran es 17 which provide a pair of grooves or slots into which is adapted to ride a cone spending plate 18 which forms an integral part of the detachable bracket member 19. Vi hile I have described the bracket as having the plate or angular base portion 18 to engage the grooves of the plate 16, I desire to have it understood that the bracket may be made in one piece and. fastened directly to the sash or frame if'desired, or otherwise anchored thereto, without departing from the spirit and scope of the invention herein defined and to be subsequently pointed out as claimed, reference being particularly bad to the construe tion of the bracket for accomplishing the objects set forth in the statement of the objects of the invention and the mounting of the rectangular spindle end of the shade roll-er, although the construction shown and'described is the preferred one. As shown more particularly in Fig. 5 of the drawings, an opening or slot 20 is provided in each bracket 19 and 19, the latter being the bracket provided for the round spindle end of the shade roller. The slot 20 is provided in the base portion 18 spaced from its inner edge and extends into the bracket proper angular relation to the plate or base 18, as indicated at21 at right angles thereto, these parts being formed integral.

The plate 16 is provided with a plurality of screw holes 22, preferably three in number, one being provided near its inner edge and two in line near its outer edge, the three openings being arranged in substantially triangular relation so that when the plate or base 18 is engaged with the grooves formed by the top and bottom flanges 17, the bracket member or part extending at right angles to the base 18 will ride over the head of a screw 23 engaging the innerhole and used for fixing the plate in position on the sash. However, as above set forth and as will be noted fro-m the drawings, since the slot 20 does not extend completely through the plate or base 18, when the bracket is applied to the fixed plate 16 with'the edges thereof sliding under the lugs 0r flanges 17, the inner end of the slot 20 will form a stop to engage the screw23, so that the position of the bracket will be auto matically determined by the contact of the' forward end of the slot with the screw which also serves as an anchoring means'for the plate and thereby limits the outward displacement of the bracket proper on its fixed mounting member or plate 16. After the shade roller is then applied to thebracket there is no possibility of the roller becoming detached or falling off in'use as the pressure against the brackets 19 and 19 acts only in the direction to force the rear end of the slot 20 more firmly against the wood screw or otherfastening means which maintain the plate 16 in position.

In connection with the screws 24 which engage the outer two' holes of each plate 16, the brackets 19 and 19 as shown more particularly in Figs. 4 and 5 of the drawnigs are provided'with ribs, and indentations'25 which stiffen the bracket at the bend and accommodate the heads of the screws 24: in case countersunk screws are not employed, also furnishing an additional stop to limit the displacement of the bracket in its mounting. The heads of the screws do not overlie the surface of the base 18of the slot 2 0 and this prevents the formation of a' leverage tending to lift the screws from their securing posi-v tion and provides for firmly securing the mounting member 16 to the sash. The screws 24 also provide the greatest securing strength near the outer portion of the, plate 16 so that should the top of the lower sash or check rail strike the bracket at its bottom edge and corner 26, dislodgement of the fastening means and parts of the brackets will prevented. Furthermore, owing tothe corner portion 26 engaging the comparatively soft wood of the sash as shown in Fig. 4 of the drawings, the impact will be cushioned and shock absorbedowing to the metal'of the bracket slightly sinking or embedding into the wood, thus relieving the fastening screws of the bracket of unnecessary stresses.

As Will be observed from the drawings, and particularly in Figs. 3, 4 and 5, the brackets 19 and 19 are of angular formation in plan, the bracket proper extending substantially at right angles to the securing portion or base plate 18 which latter fits fiat against the anchoring member or sash, and after extending perpendicularly fromthe sash, is offset or bent outwardly at an obtuse angle, sul stantially at right angles, as indicated at 27 and then forwardly in an obtuse angle, substantially at right angles, as indicated at 28 parallel to the main portion between the )filllS 18 and 27 but offsetoutwardly therefrom and then bent inwardly at obtuse angles, substantially at right angles, as indicated at 29 to provide a comparatively deep offset or outwardly curved bend adapted to accommodate the edge of the shade, and in which the latter is adapted to track as it is moved up and down to raise and lower the shade30 and to wind and unwind the same upon and from the roller 31 without engaging or 'mutilating the side edges of the shade. Furthermore, the outer portion 32 at the s end of the bracket is offset outwardly with relation to the inner portion but is disposed inwardly from the portion 28 and therefore the portion 27 forms a shoulder or serves as a stop to engage the shade slat 33 at the bottom or thickened portion whereby the end of the shade will be prevented from running over the roller and unwinding therefrom when once wound thereon and set or adjusted to a proper position with proper spring tension to cause complete winding of the shade upon the roller. That is, the slat will not be permitted to pass the portion 27 but will. be held or wedged between the shade and the bracket at the part 27, as indicated in Fig. l of the drawings. shade from blowing or flapping under the action of air currents entering the room above the upper sash when the latter is lowered for ventilation, in addition to the fact that the shade is attached to the upper sash and lowered therewith so as to be primarily free from being blown, torn or causing any rattling incidentto the air curren Another important improvement in the bracket and constituting a distinctively novel part of the same, is at the part 32whichis This will also prevent the shown substantially circular in face view, in

the preferred construction and provided with e a vertical slot 34 of substantially rectangular V contour, to receive and lit the rectangular spindle end 35 of the shade roller 31. It will disposed over and rearwardly oi the hon while the front portion is provided with an upward and rearward extension at the top of the outer portion 32, thus providing a slot at the top portion oi'f the bracket entering from the rear on a. level with the top edge of the bracket, and providing an overhanging part or hood 37 at the top overlying the vertical slot 3a, to prevent the spindle end of the shade from being forced up out of the slot or hearing and thereby preventing displacement of the shade roller from the bracket. The overhanging part or hood may be of any suitable length, that is, its degree of extension rearwardly beyond the vertical portion ot the slot and the top edge of the bracket rearwardly of he vertical portion ofthe slot Pi l, may be varied, with relation to the sash cord 15 from a point in close proximity to said sasn, cord to a point alongside of or in rear of the same, thus necessitating that the sash cord be displaced rearwar when the rectangular spindle end of the roller inserted into the slot or removed therefrom. In this connection, it is pointed out that the opposite bracket is construct d in the same way except that it is provided with a circular bearing or opening to receive the round spindle end 39 of the shade roller and the bracket 19" is attached to the upper sash in the manner set forth above.

The corner of the slot at the top edge of the bracket 19 where the entrance portion 36 leads into the vertical portion 2a, is rounded off as indicated at 40 to guide and permit the rectangular spindle end of the shade roller to pass into and out of the vertical portion of the slot, which action would not be possible were the corner lett square, unless the slot was made unnecessarily wide or otherwise formed for this purpose. However, when the spindle end is in position in the vertical portion of the slot, it will be retained in, this posi tion by the vertical portion below the rounded corner in conjunction with the opposite side wall and held from turning during the winding and unwinding of the shade.v hen the spindleend 35 is moved into and out of slot, it will be turned owi. to the rounded portion 4-0 and guided or permitted to pass from the horizontal portion into the vertical portion and vice ver by applying upward pressureon the roller and then rearward pr "e, or lorward nessure and then downward pressure. Thus, when the shade is hi; i the round end of the spindle inserted in the bracket hole 38, preferably after slightly lowering the upper sash, and then the rec angular spindle end is in (ii) constituting the top guard of the slot 34: to prevent displacement oi"? the rectangular spindle end of the roller in an upward direction, and then moved forwardly through the en trance portion 36 and finally turned into the vertical portion 34s as previously explained. Removal of the shade is accon'iplished by reversing the action just described, which however may be readily and easily accomplished as it is thought will be apparent. From. 3 of the drawings, it will be noted that the outer portion 32 of each bracket is disposed slightly inwardly ot' the inner face of the beans 10 constituting the inner stop of the window, that the portion 28 is offset into the groove between the center parting strip 9 and the stop 10, and that the spindle ends of the roller also extend into said grooves or slideways, thus accon'imodating a shade roller of extra length and a shade of extra width so that the edges will. lie in close proximity to the stop 10 and obviate the usual extrawide SPRCQF; or gaps between the side edges of the shade and the Window frame present with shades as heretofore hung.

It will thus be seen that the device thus provided will provide effectively for ventilation of rooms and at the same time altord proper privacy by means of shades which can be drawn down as far as desired but left open at the top. In addition, the length of the bracket is such that the shade will be rolled from the inside and passed over the face of the outer or lower sash without contacting therewith, while also avoiding unnecessarily longbrackets. Furthermore, no obstruction will be encountered between the movement of the sashes one past the other, as the top or check-rail of the lower sash will clear the upper sash by removing the shade and brackets when itis desired to move one sash past the other for cleaning purposes, and this will mean that the shade will be removed and dusted off so that its life of usefulness will be lengthened and its condition maintained sanitary and clean. In other words. the top or check-rail of the lower sash will clear and pass by the anchoring member or plate 16 when the brackets proper are removed therefrom by sliding the base portion 18 of the bracket out of the grooves 17, but the brackets can be readily hung by reinserting the base portions into the grooves. Where the brackets are attached directly to the frame or otherwise without rendering the same detachable V or constructing the same in two parts as described, so that the base portion or plate 18 forms an anchoring means, the same advantages accrue from the formation of the rectangular spindle receiving part including the slots 34 and 36 and the overhanging hood or guard parts 87.

I am, aware that many changes may be made on numerous details of construction therein throughout the wide range without departing from the principles of this invention and I therefore do not purpose limiting the patent granted hereon otherwise than as necessitated by the prior art.

Having thus described my invention, what I claim is:

1. A support, a grooved slide fixed to said support and having stop projections extending from the face thereof, a shade supporting bracket slidable into said slide and having recesses formed therein to receive said projections and limit-said sliding movement. I

2. A support, a grooved slide, screws with projecting heads securing said slide to said support, a shade-supporting bracket slidably mounted in said slide and. having recesses adapted to receive the heads of said screws whereby said bracket is properly positioned on the slide. 7 v

,3. A support, a grooved slide, screws securing said slide to said support and. having heads projecting from said slide, a shadesupporting bracket slidably mounted in said of plates associated with the window, bracket members having one end of each slidably adjustably secured in said plates for varying V the relative distance of said members, a roller curtain pivoted between the free ends of said brackets, and having a curtain stick at its free end, each of said brackets being shaped to form a channel, said channels opening inwardly and said brackets spaced apart to provide clearance for the edge of said ourtam in said channels, one wall of each of said channels being spaced to engage the-ends of said stick when the curtain is fully rolled and prevent the passage thereof past said brackets. i

In testimony whereof I afiix my signature.
