.Application filed April 1920. serial No. 374,786. a

To all whom it may concern Be it known that Frances M. CoNs'rAnLn,

a citizen of the United States,.residing at Columbus, in the'county of Franklin and State of Ohio, has invented certain new and useful Improvements in Curtain-Stretchers,

of which the following is a specification.

This invention relates to curtain stretchers, and has for its primary object to provide a curtain stretcher of novel, simple and improved construction, and which is of such form that the same may be readily connected with a window frame oimotlier equivalent structure for the purpose of stretching curtains While the same are applied to the frame.

In carrying out the invention, I ably employa plurality of brackets which are of such construction that the same may be detachably clamped to the sill of a window frame and to provide a vertically ,adjustable stretcher bar in connection with said brackets with-which the lower edges of .a curtain may be detachably connected, whereby upon the verticlal'adjustment of the bar with respect to said brackets, the necessary tension may be imparted to the curtain to effect the desired stretching of the latter.

Another object of the invention resides in a curtain stretcher which is of simple and economical formation, may be readily applied in its operative position and when not in use will be of such proportion and construction as to occupy but a minimum of storage space.

With these and other objects in view, as will appear as the description proceeds, the invention accordingly consists, in the novel features of construction, combinations of elements and arrangement of parts, hereinand to have the scope thereof pointed out in the appended claims.

In the accompanying drawing, forming a part of this specification and in which similar characters corresponding views thereof:

Fig. 3 is a detail verticalitransverse sectional view taken through the stretcher.

The curtain stretcher 1 comprising the presentinvention consists essentially of a horizontally disposed stretching bar '2. This bar is of the usual formation provided in a a curtain stretcher constructions, and ispreferably formed from wood, the same embodying the usual longitudinally disposed pins 3 with which the lower edge of a curtain 4 is bar 2 is arranged to be adjustably carried byv a pair of metallic brackets 5. These brackets are of angular formation and are so constructed as to embody vertically disposed legs 6, angularly disposed terminating ends 7 and sill engaging ledges 8. The legs 6, asshown, are provided with elongated yertically disposed slots 9 which are of such width as to receive the horizontally disposed shanksof clamping bolts 10. Theheads of these bolts are arranged on the inner sides of the legs 6, and the shanks thereof are so dis posed as to extend through the 'slotsf9. and also through elongated horizontally disposed slots 11 provided in the ends of the bar 2. Threaded ends of the bolts 10 are arranged to receive wing nuts or their equivalents 12, which are adapted to be threaded into engagement with wear receiving washers 13 which are so disposed as to protect the material of the bar from being damaged by the pressure exercised when said, nuts occupy their clamping positions; The ends 70f the brackets are also provided with threaded openings which are arranged to receive vertically disposed clamping screws 14, the latter being moved relatively toward or away from the ledges 8 and are provided with felt covered ends 15.

In operation, the stretcher is set up in its applied position by locating the brackets 5 at the opposite ends of a window sill 16, said sill being received between the upper ends 7 of said brackets and the ledges 8. The brackets are then firmly yet detachably clam ed to the sill by rotating the screws 14. his results in causing said screws to frictionally engage with the upper surface of the sill with ample and su clent pressure to maintain the positions. By protecting the ends 15 of the screws, it willbe obvious that the window frame construction will not be damaged by the engagement of the screws therewith.

This brackets in their applied The upper edges of the curtain l may be connected with the window frame 17 inany suitable manner, such for example by means of rods 18, normally found to effect the support of the curtain, while the lower edgeof the latter is connected to the bar2 by means of the pins 8. stretcher as a wholemay to the width of a curtain, and this is effected :by shifting the longitudinal positions of the brackets 5 upon the'sill 16, the horizontal slots 11 in the ends of the bar 2- serving to adapt the latter to this horizontal adjustment. The desired tension may be then placed upon thevcurtain a by lowering or raising the bar 2 relatively to the brackets 5. This allows the bolts 10 to loosely slide within the slots 9, and when the desired adjustment is reached, the same may be maintained by threading the wing nuts 12 inwardly. upon the threaded ends of the bolts 10. This results in frictionallyclamping the bar -52 in a rigid manner with the brackets 5 and thus prevents unduemovement on the part of said bar.

From the foregoing description, taken in conjunction with the accompanyingdrawing, it will'be apparent that there is provided a curtain stretcher of very simple yet efficient construction and one of considerable utility in its particular field. The very simplicity of the stretcher enables the latter to bequickly set up for use and by being attachable to a window frame, the same will ,tains to such lengths as will be It will be noted that the be adapted readily to stretch accompanying curnecessary to adapt the curtains to the proportions of the window frame. WVhen not in use, the

enable its user stretcher will occupy but a minimum of storage space and furthermore said stretcher may be admirably used in restricted areas.

What is claimed is:

1. A curtain stretcher for window frames comprising a pair of angular brackets, threaded means for detachably securing said brackets at various longitudinal positions upon the sill of a window frame, a stretcher to which the edges of a curtain may be secured, and'clamping screws connecting said bar with said brackets'for vertical and horizontal adjustments with regard thereto. 7

2. A curtain stretcher for window frames, comprising a pair of spaced brackets, said brackets being formed to include vertically slotted legs, the upper ends of said legs being 'angula-rly bent, a clamping screw threadedly carried by said ends, a. sill engaging ledge stationarily carried by said brackets and toward which. said screws are relatively movable, a stretcher bar horizontally connecting saidbrackets, and clamping screws passing through said bar and through the vertical slots of said legs to permit of vertical adjustment on the part of said bar.

In testimony whereof I affix my signature.
