ADJUSTABLE BRACKET Filed June 29, 1939 IN VENTOR.

A TTORNEYS Patented Apr. 23, 1940 ADJUSTABLE BRACKET Alfred Peckham, Sturgis, Mich., assignor to Kirsch Company, Sturgis, Mich.

Application June 29, 1939, Serial No. 281,933

19 Claims.

This invention relates to improvements in adjustable brackets.

This invention relates to brackets for swinging curtain rods or cranes or for similar curtain 5 rods which are supported at one end only. Heretofore such curtain rods or cranes have been provided with brackets attachable to the wall by means of attaching screws or the like and it has been difiicult to place the brackets so as to be sure that when curtains or draperies are hung upon the rods, the rods will be level. Various adjusting means have been employed but have not been entirely satisfactory.

The objects of this invention are:

First, to provide a new and improved bracket for swinging curtain rods or the like.

Second, to provide such a bracket which is easily adjustable to level the curtain rod either before or after the drapes or curtains have been hung thereon.

Third, to provide such a bracket which may be easily and simply adjusted by means of a screw driver and in which the one adjusting the bracket may position himself out away from the window during the adjusting to simplify the leveling of the curtain rod.

Fourth, toprovide such a bracket which is unitary in its nature and which may be inexpensively produced.

Other objects and advantages pertaining to details and economies of construction and operation will appear from the description to follow. Preferred embodiments of my invention are illustrated in the accompanying drawing, in 35 which:

Fig. 1 is a perspective view of my improved bracket showing in dotted lines how the bracket may be easily adjusted from the front by means of a common screw driver} V 40 Fig. 2 is a front face view of a bracket made according to my invention showing in dotted lines the positions to which the bracket may be adjusted.

Fig. 3 is a detail sectional view of the lower 45 portion of my bracket taken on the line 33 of Fig. 4.

Fig. 4 is a detail view from the front of the adjusting portion of the bracket, with the cam in section.

Fig. 5 is a detail view of the adjusting portion of the bracket, showing a slightly modified form of the invention shown in Figs. 1-4.

- Fig. 6 is a detail view of the lower portion of a modified form of the invention showing a 5; slightly diiferent type of adjusting mechanism.

Fig. 7 is a detail sectional view taken on line I'! of Fig. 6.

In Fig. 1, I show my improved bracket l attached to a. window casing or wall 2. I show a swinging curtain rod 3 attached by pivot 4 to the bracket I, although it will be apparent that my invention is applicable to similar curtain rods supported at one end and not pivoted to the bracket. The bracket is made of sheet metal and the sheet metal base 5 which lies flat against the wall is provided at its upper end with a hole 6 to pivotally receive an attaching screw 1.

The lower portion 8 of the base is slightly offset from. the rest of the base and is provided with an elongated slot 9 extending upwardly from the lower end of the bracket. A cam'lll is rotatably disposed in said slot and engages the sides of the slot. The periphery of the cam is provided with a groove H into which the edges of the slot fit so that the cam will be retained in the slot, making a unitary bracket structure. The cam I is provided with an eccentrically disposed hole [2 to pivotally receive an attaching screw 13. The side of the cam is provided with a slot I4 to receive a screw driver, as shown in dotted lines in Fig. 1, so that the cam may be rotated about the screw l3 as an axis.

I prefer to have the slot I4 extend radially from the hole {2 as shown. In the form of invention shown in Figs. 1-4, the sheet metal of the base is formed to provide ears l5 which,

after the cam H] is placed in the slot, are bent inwardly as shown, so that the cam will not fall out of the slot so that there is a complete unitary structure.

In use my bracket is attached to the wall or window casing by means of the screw I extending through the hole 6. The rod is roughly leveled with the cam I0 in the position shown in Fig. 1 and the screw I3 is screwed into place but not completely to position. I prefer to have the screw tight enough to hold the cam. in position against the wall or window casing, but not tight enough to'prevent turning of the cam. by insertion of a screw driver in the slot M. It may be possible to accomplish the adjustment without tightening the screw I 3 to this extent if the frictional engagement between the wall and the base of the bracket is sufiicient to momentarily hold the bracket in adjusted position. The finalv leveling of the bracket is accomplished by making use of a screwdriver l5 shown in dotted lines in Fig. l, which is grasped by the hand I6 of the one adjusting the bracket who may, because of the arrangement of the slot, positioni himself out in front of the window so as to be able to determine when the bracket has been adjusted to a proper level. This can be accomplished easily when the curtains or drapes are on the rod, so that any sagging caused by the weight of the curtains or draperies can be compensated for during adjustment.

After the proper level has been obtained by adjustment, the screw 13 is tightened so that frictional engagement between the back of the cam l6 and the wall or window casing holds the cam in desired position and thus holds the rod in adjusted position. The upper screw 7 also may be tightened to assist in holding the bracket in position.

In Fig. 5, I show a slightly modified form. of the invention. Instead of forming the ears 5 at the bottom of the slot 9 and bending such ears in, I merely deform the metal in a press as indicated at H5, so that the cam H0 cannot slip from the slot. The bracket i515 and cam l H] are otherwise identical, in this form of the invention, with those shown in Figs. 1-4.

In Figs. 6 and '7, I show a further modification of the invention. The lower portion 208 of the bracket 205 is not offset from the wall as in the form of invention shown in Figs. 1-4 or in Fig. 5. The slot 209 is vertically elongated and receives a cam 2H) which does not have a peripheral groove. The cam 2H1 fits in the slot 209 for rotation and is provided with the hole 2l2 eccentrically located and the slot 2H4 to receive a screw driver is similar to the slot 14 of the form of invention shown in Figs. 1-4 and functions in the same way. The adjustment of the bracket and the rod is obtained in the same way, but the cam is not held in position to form a unitary structure. The rod is held in adjusted position by having the screw 2l3 clamp the cam 2 I0 tightly against the wall or window casing.

It will be apparent that one can modify the structure above described without departing from my invention and I do not wish to be limited to the specific form of the invention shown. I

.have defined the invention in the appended claims.
