CURTAIN-BRACKET.

Specification of Letters Patent.

Patented Dec. 14:, 1%15.

Application filed November 23, 1914. Serial No. 873,575.

which the following is a specification.

My invention relates to curtain brackets and particularly to brackets of the adjustabletype movable laterally to accommodate blindsand other hangings of diii'erent width.

The object of the invention is to simplify the structure as well as the means and mode of operation of such devices whereby they will not only be cheapened in construction butwill be more eiiicient in use, easily adjustable, capable of being rigidly engaged in adjusted position, and unlikely to get out of repair. 7

Vith the above primary and other incidental objects in view, as will more fully appear in the specification, the invention consists of the features of construction, the parts andcombinations thereof, and the mode of operation, or their equivalents, as hereinafter described and set forth in the claims.

Referring to the drawings, Figure 1 is a perspective view of the adjustable curtain and blind bracket forming the subject matter hereof. Fig. 2 is a side elevation of the construction shown in Fig. 1, the shape of the supporting arm belng slightly changed.

Fig. 3 is a detail view of the engaging portion of the adjustable arm removed from the support or frame. Fig. 4 is a perspective view of a modification of the device embodying a locking means for positively engaging the adjustable arm with the support in its adjusted position. Fig. 5 is a side elevation of the assembled device showing a further modification of the locking means. Fig. 6 is a detail perspective view of the locking pawl employed in the construction shown in Fig. 5. Fig. 7 is a side elevation of a separable supporting arm, the sections of which are adapted to be interengaged one with the other in alternative relation. Figs. 8 and 9 are detail views of the interengaging parts by which the respective sections of the supporting arms shown in Fig. 7 are engaged one with the other. Fig. 10 is an end view of the supporting arm. Fig. 11 is a detail view of a modification of the frame.

Like parts are indicated by similar char acters of reference throughout the several views.

The curtain and blind bracket forming the subject matter hereof is designed to obviate the necessity for relocation of the supporting brackets for blinds or other draperies of different width. lhe readjustment of the blind brackets or supports, particula-rly in rented houses where each tenant is provided with blinds of different width, causes the woodwork to become badly marred.

window may be adjusted to and from each other throughout an extended range of movement sufficient to accommodate blinds of various width without changing the con nection of the device with the window frame.

The blind bracket or support herein clescribed comprises a frame member or support 1 adapted to be secured to the window frame, wall, or other structure, and an adjustable supporting arm 2 capable of lateral movement upon the base or frame 1 to various positions thereon and in addition to its lateral movement is capable of a limited vertical movement by which the supporting arm is securely engaged with the frame or support in its adjusted position. The frame or support 1 comprises a plate having in its upper edge a series of spaced notches or open slots 8 and adjacent to its opposite edge a series of holes or slots 4 closed at both ends. The plate is flanged or flared outward adjacent to its lower edge. The shape of the plate is such that the holes or slots 4 are located in the flanged or flaring portion of the plate. In the drawing the plate has been shown provided with an arcuate flange. It is obvious that the perfora-ted lower portion of the plate may be bent outward in angular relation with the upper portion of the plate as in Fig. 11. At the opposite ends the plate is provided with extensions 5 which are turned rearward for a limited distance and then outward in parallel relation with the plate to form attachment ears by which the frame or support is secured to the window structure. If so desired, the lower flange or arcuate edge of the plate may be notched similar to the upper edge. In other words the slots l may be formed with open ends similar to the slots or notches 3, the sole object in forming the slots 2 with closed ends is to provide a continuous lower edge for the plate to assist in guiding the sup By the use of the present device the brackets at the opposite sides of the porting arm in its lateral movement. If the holes or slots ff were open at their ends there might be a tendency for the supporting arm to engage in such notches during its sliding movement and thereby interfere with the quick adjustment of the device. As shown in Fig. 1, the edge of the frame forms a continuous bearing upon which the arm slides. It is obvious that in the event the slots L in the lower or flanged edge of the suppport are open at their ends, as before mentioned, the extension 8 of the slot 67 may be omitted as the object of the extension S is to receive the closed end of the slot i when the supporting arm is depressed.

The supporting arm 2 comprises a flat plate having therein a vertical slot 6 terminatingat its lower end in an arcuate portion 7 which communicates with a vertical extension 8 of the slot thereby forming intermediate the extension 8 and the main portion 6 of the slot a tongue 9. The frame or support 1 is introduced through the slot o-78 by first introducing the ear and turning the frame or support to enable the supporting arm to pass the angles of the extension of the plate until the arm passes into the main portion of the frame, as shown in Fig. 2. Vhen in this position the supporting arm 2 may be slidingly adjusted to and fro upon the frame or sup port 1,.

\Vhen the supporting arm has been moved to the desired position it is pressed downward through a limited vertical movement,

' as indicated by dotted lines in Fig. 2. This movement causes the tongue 9 to be projected through one of the slots or holes in the flanged portion of the plate and at the same time causes the portion of the plate immediately above the main slot 6 to extend within the corresponding notch or slot 3 in the upper edge of the plate. The engagement of the tongue 9 in the slot or hole at the bottom of the plate and the engagement of the upper portion of the arm in the slot 3 secures the supporting arm against further lateral movement and securely holds it against any tipping or tilting movement in relation with the supporting frame 1.

To cause a more rigid engagement of the supporting arm with the frame, the tongue 9 may be bent slightly out of alinement with the plane of the supporting arm, as shown in Fig. 10. By so doing the tongue 9 is placed under tension when forced downward into the opening or slot L and thereby provides a frictional engagement with the side of the slot tending to resist displacement of the supporting arm.

The particular shape of the extension of the supporting arm is immaterial. In Fig. l the arm is shown provided with two triangular notches 10 adapted to receive the supporting rod for a drapery or curtain. In Fig. 2 the arm is shown with a semicircular recess of comparatively large size to accommodate a curtain pole.

There is provided in the supporting arm 2 an opening 12 within which the trunnion of a roller blind 13 may be engaged. The opening 12 for the reception of the blind roller trunnion. comprises preferably a circular central portion having oppositely disposed notches or slots. The blind rollers commonly in use are provided with a round or cylindrical trunnion at one end and with a. flat trunnion at the opposite end. The hole or socket 12, as shown in the drawing, is adapted to accommodate either the round or flat trunnion. Thus the supporting arms are either right or left handed and may be used interchangeably. The usual boss or bearing 14 is provided around the trunnion socket.

If so desired, various means may be employed for positively locking the supporting arm in its depressed position. Although the frictional engagement ofthe unalined tongue 9, as previously described, will be found sufficient under ordinary circumstances, as a further precaution the tongue 9 may be provided with a hole 15 through which a retaining pin or cotter may be introduced after the parts have been adjusted. Such pin or cotter will prevent the withdrawal of the tongue 9 from the hole or. slot 1. r

In Fig. there is shown other means for locking the supporting arm 1n its depressed or adjusted position comprising a spring tongue or depressible bar 16 formed by V I slotting the main or central portion of the supporting frame 1. The main slot 6 of the supporting arm 2 is provided with a lateral notch or recess 17 so located that the spring tongue or depressible bar 16 will adjacent to the slotted extension Sand bent iv 7 upon itself to parallelism about the side of the opening. The shape and proportion of the detent is such that when resting upon the bottom of the opening 19 the preponderance of the weight of the detent on the side adjacent to the frame will cause it to be oscillated beneath the flanged edge of the frame or support 1 thereby locking the supporting arm against withdrawal. The detent 18 is preferably provided with the project- I ing arm 20 by which the device may be con- =veniently Withdrawn from looking position.

the lower edge of the frame or support 1 will accomplish the same purpose.

In Fig. 7 thereis shown a modification embodying an independent reversible exten-.

"sion 23 up'onthe'supporting arm whichinay be lnteren'gaged with the frame engaging portion ofthe arm in either one of lllS posi- 15 tions. This independent arm is provided with af' large semicircular recess'upon one edge to engage a curtain or drapery pole of large diameter and is'pro-vided with two triangular recesses or notches in the opposite edge to engage rods of small diameter. The main portion 22 of the supportingarm is provided with the slot 6-78 and the trimnion socket 14: as before described. To detachably engage-the main portion 22 and the detachable extension 23 one with the other, one of said members is provided with -T shaped tongues 24: and 25 projecting perpendicular to the plane thereof; In the drawing these tongues have been shown upon the detachableextension as in Fig. 9. They might be located on thefmain portion '22. The other member is provided with two openings 26 and 27. These openings comprise 'slots substantially equal in size with the tongues 2d and 25 and correspondingly positioned in relation one with the other. Theslots, however, are arranged in angular relation with the normal position" of the tongues upon the independent extension. The slot or opening 26 is provided-with a triangular notch or recess in one side thereof, the "side of said notch corresponding with the normalposition of the tongue 24. The other slot or opening 27 isintersected by an arcuate slot 28 concentric with one end of the slot 26. The terminal of the-slot 28 corresponds with the normal position of the tongue 25 when the parts are interengaged one with the other.

' To interengage the partsthe tongues 24: and 25 are inserted through the corresponding openings 26 and 27 and the independent extension is pressed upward to bring the stem of the T; shaped tongue 24: into the lateral recess or notch of the slot 26. The independent extension is then oscillated about the bearing of the stem of the tongue upon. the end of the slot 26 causing the stem of the tongue 25 to travel through the arcuate slot 28 until it engages the end of said slot. The stem of the tongue 24 then rests upon the shoulder of the offset or notch of the slot 26 which forms a fulcrum for the independent extension 23, the oscillatory movement of which is resisted by the engagement of the stein of the tongue 25 with the end of the slot 28.. r

To provide an increased bearing for the supporting arm upontheframe, the material of the arm adjacent to the slot 6 is bent in opposite directions, as shown in Fig. 10. The material intermediate the slot 6 and the edge of the arm is deflected beyond the plane of the plate in one direction and the material adjacent to the opposite side of the slot is deflected in the other direction. This provides a bracing effect which tends to resist any lateral oscillation. a

From the above description it will-be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enu- -.1nera'te'd as desirable but which obviously is susceptible of modification in its form, proportion, detail construction or arrangement of parts, without departing from the principleinvolved or sacrificing vantages.

While in order to comply with the statute the invention has been described in language more or less specific as to certain structural any of its ad- -features, it is to be understood that the invention is not limited to any specific details, but that the means and construction herein described comprise but one mode of putting the invention into effect, and the invention is thereforeclaimed broadly in any of its possible forms or modifications Withinthe scope of the appended claims.
