O. R. MEYER. ADJUSTABLE CURTAIN SUPPORT.

APPLICATION FILED DEG.-l8, 1908.

Patented Feb. 22, 1910.

N1 sns i r a ADJUSTABLE CURTAIN-SUPPORT.

To all whom it may concern:

Be it known that 1, CHARLES R. MEYER, a citizen of the United States, residing at- Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Adjustable Curtain-Supports, of which the following is a specification.

My invention relates to window curtain appliances, and particularly to an adjustable bracket or support for window blinds and curtains or portieres.

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, but will be more efiicient in operation, pleasing in appearance, easily and readily adjust ed to accommodate different sizes of ourtain rolls or rods, and unlikely to get out of repair.

With the above primary and other incidental objects in view, as will more fully ap pear in the specification, the invention consists of the devices, the features of construction, parts and combinations 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 view showing the upper portion of the window with the improved adjustable curtain support forming the subject matter hereof attached to the window-casing and supporting the roller blind and the curtain rod. Fig. 2 is a perspective view of the adjustable supporting device removed from the window-casing. Fig. 3 is a detail perspective view partly in section, of the main frame member viewed from the rear. Fig. 4: is a detail transverse sectional view showing in dotted lines the movement of the bracket for the purpose of longitudinal adjustment. Fig. 5 is a detail view similar to Fig. 4, showing a slight modification.

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

Referring to the drawings, 1 is the window surrounded by the casing 2 to which is secured the adjustable support which carries the roller blind 3 of ordinary construction and also the curtain rod 4 from which is suspended the curtain 5.

In constructing the adjustable support there is employed a main frame member 6 Specification of Letters Patent.

formed hollow or of a somewhat box-like construction. The frame member 6 is provided, in its forward side, with a longitudinal slot 7 along the lower edge of which and on the inner side is located a longitudinal head 8. On the outer face of the frame member 6 and parallel with the slot 7 is a series 9 of serrations. A similar series 10 of serrations is located on the inner side of the frame member 6 and at the opposite side of the longitudinal slot 7 The frame member is provided with lugs or ears 11 by which it may be secured to the window-casing by screws passing through said ears. At the lower rear portion of the member is provided a projecting ledge 12 adapted to project beneath the heading of the windowcasing enabling the frame to be adjusted square with the window and closing any unsightly opening which might otherwise exist between the member and the windowcasing thereby, improving the appearance of the device or it may be omitted if desired.

Slidingly mounted in the member 6 is a supporting bracket which may be of any desired form, the usual supporting brackets for the roller blinds being shown at 13 and 14, while at 15 is shown an arm bifurcated or forked at its extremity and adapted to support the curtain rod l. Whatever the shape of the supporting bracket may be, the connection of the same with the main frame member 6 will be identical. The upper portion of the bracket is off-set as at 16 and extends within the frame member 6 through the slot 7 and is provided with one or more teeth 17 to engage the serrations 10 on the inner side of the frame member. Below the slot 7, the bracket extends substantially parallel with the face of the frame member for a limited distance, and is provided with one or more teeth 18 adapted to engage the serrations 9 on the outer side of the frame member. On the inner side of the bracket is provided a projecting lip 19 engaging over the bead 8 and forming a fulcrum for the bracket whereby the bracket will be capable of oscillation upon the longitudinal head 8 in addition to its sliding or longitudinal movement within the slot 7. There is provided at the rear of the main frame member 6 a longitudinal bar 20 forming a bearing for a spring which engages the bracket at a point above its fulcrum and tends to move the bracket about its fulcrum point and cause a simultaneous engagement of the teeth 17 with the serrations 10 and the teeth 18 with the serrations 9.

In Fig. 4 is shown a plunger 21 mounted in the bracket member and having a head 22 bearing on the bar 20. A helical spring 23 surrounds the plunger and is interposed between the bracket and the head 22. By this construction the head 22 of the plunger forms the bearing surface which rides on the bar 20 as the bracket is longitudinally adjusted on the frame member. It is obvious, however, that the plunger 21 might be omitted and the spring 23 alone employed which would then operate at one end on the bracket as now and at the opposite end on the bar 20.

lVhen it is desired to shift the bracket in the main member in order to accommodate a curtain roll of difierent length, the bracket is pulled out or away from the frame member as indicated in dotted lines in Fig. l oscillating on the bead 8 engaged by the lip 19 until the teeth 17 and 18 are disengaged from the serrations 10 and 9, which movement also compresses the helical spring 23. The bracket may then be moved longitudinally within the slot 7 to the desired position and upon being released, the bracket will return to normal position with the respective teeth 17 and 18 engaging the serrations 10 and 9 through the action of the spring 23.

In Fig. 5 is shown a modification in which the set screw 24; is substituted for the helical spring 23. The set screw 24 engages the longitudinal bar 20 and by further operation tends to oscillate the bracket to engage it with the serrations in the same manner as the spring. In order to shift the bracket with this construction, it would be necessary to first release the set screw 24. As shown in Figs. 1 and 2 both the bracket supporting the blind and the bracket supporting the curtain rod may be carried in the same frame member as before stated the method of engaging these brackets with the main member is identical. However, if only one bracket is required the other may be omitted without in any way impairing the action of the device.

From. the above description it will be apparent that there is thus produced an ad.- justable curtain support of the character described, possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportion, detail construction, and arrangement of parts, without departing from the principle involved or sacrificing any of its advantages.

Having thus described my invention, I claim:

1. In an adjustable curtain support, a

. recessed frame member having a longitudinal slot therein, and a series of serrations adjacent to said slot and on the inner side of said recessed frame member in combina tion with a bracket slidingly mounted within said slot and adapted to engage the serrations, and a spring yieldingly holding the bracket in engagement with the serrations, substantially as specified.

2. In an adjustable curtain support, a frame member having a longitudinal slot therein, serrations adjacent to said slot, a longitudinal bead adjacent to the slot, in combination with a movable bracket slidingly mounted in said slot and adapted to fulcrum on said bead, means for moving said bracket about its fulcrum on said bead whereby it will be caused to engage said serrations, substantially as specified.

3. In an adjustable curtain support, a recessed frame member having a longitudinal slot therein, two series of serrations in said member located at opposite sides of the slot, one of said series being on the outer side of the member, and the other series on the inner side thereof, and a bracket adjustably mounted in said slot and adapted to simultaneously engage both series of serrations, substantially as specified.
