CHRISTIAN HEILRATH, OF SACRAMENTO, CALIFORNIA.

ADJUSTABLE SHADE-BRACKET.

SPECIFICATION forming part of Letters Patent No. 784,490, dated March '7, 1905.

Application filed June 24,1904. Serial No. 214,049.

l T0 ctZZ whom it may concern.-

Be it known that I, CHRISTIAN HEILRATH, a citizen of the United States, residing at Sacramento, in the county of Sacramento and State of California, have invented a new and useful Adjustable Shade-Bracket, of which the following is a specification.

The invention relates to improvements in adjustable shade-brackets.

The object. of the present invention is to improve the construction of window-shade brackets and to provide a simple, inexpensive, and efficient one of great strength and durability adapted to be attached to a window frame or casing by a single fastening device and capable of ready adjustment to suit shaderollers of different lengths without changing the fastening device, whereby the injury to window frames or casings resulting from the frequent changing of fastening devices is prevented.

A further object of the invention is to provide a device of this character in which the means for adjustably securing the bracket to a window-frame will be concealed beneath or behind the shade-roller.

\Vith these and'other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of an adjustable shade-bracket construct ed in accordance with this invention and illustrating the arrangement of the parts when the bracket is clamped against the wind0\ frame. Fig. 2 is a longitudinal sectional ,view of the same. Fig. 3 is a transverse sectional view. Fig. 4 is an elevation, the cam-lever being arranged for releasing the bracket. Fig. 5 is a perspective view of the bracket, illustrating the construction of the slotted arm. Fig. 6

is a detail perspective view of the cam-lever.

Fig. 7 is a detail view illustrating the construction of the wedge-shaped head of the cam-lever.

Like numerals of reference designate corresponding parts in all the figures of the drawings. 4

1 designates an adjustable shade-bracket adapted to support one end of a shade-roller in the usual manner and provided with an inwardly-extending arm 2,forming a base-plate and adapted to fit against the top of a window'- frame 3 in the ordinary manner. The arm 2 is arranged horizontally and extends inwardly from the bracket, so as to lie beneath or be' hind the shade-roller when the latter is in position, whereby the means for adjust-ably mounting the bracket on the window-frame will be concealed by the roller. The arm 2 is provided with a longitudinal slot 4 to receive a screw 5 or other fastening device for mounting a cam-lever 6 on the window-frame. The screw passes through the slot 4, and the bracket is capable of longitudinal adjustment, as will be readily understood. The cam-lever is provided at one end with a circular head 7, which is bent transversely to form a substantially wedge-shaped head, the engaging face of which presents an intermediate apex and oppositely-inclined side faces. The head of the lever is provided with a central opening 8 to receive the screw, and it is adapted to be partially rotated thereon to arrange the apexv of the head either longitiulinally or trans versely of the arm of the bracket. \Vheu the apex is arranged transversely of the arm of the bracket, as illustrated in Figs. 1 to 3 of the drawings, the arm is forced into engagement with the window frame and is firmly clamped against the same. In this locking position the cam-lever extends longitudinally of the arm and of the shade-roller and is concealed beneath and behind the latter. \Vhen the arm is swung downward to a vertical position, as illustrated in Fig. 4 of the drawings, the apex of the head is arranged longitudinally of and extends into the slot of the arm, whereby the latter is released and is capable of adjustment to move the bracket inward and outward to enable it to be properly positioned to receive a shade-roller.

In order to enable the arm or base-plate of the bracket to be firmly engaged with the window-frame, the side portions at opposite sides of the slot are grooved or bowed transversely at their inner faces to present inner concaved faces and to provide longitudinal engaging side edges 9, which are firmly embedded in the window-frame When the lever is in its locked position. By grooving the inner faces of the side portions of the arm the body of the metal is otfset from the plane of theside edges, and each side is provided with a pair of Iongitudinal gripping edges, which are partially sunk into the window-frame. By this construction the bracket is effectually prevented from accidentally slipping. The end portion 10 of the arm is similarly'grooved or bowed to provide engaging edges.

The adjustable shade-brackets are designed to be constructed in pairs, one of the brackets being designed to be provided with an ordinary circular opening to receive the journal at one end of the shade-roller and the other being slotted, as illustrated in the accompanying drawings, to receive the journal which is connected with the spring of the roller.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1 An adjustable shade-bracket having a slotted arm, said arm being provided at opposite sides of its slot with projecting longitudinal edges arranged in pairs, a fastening device arranged in the slot, and means pivotally mounted on the fastening device for engaging the arm to force the saidedges into the supporting-surface, said means being also arranged to release the arm for adjusting the bracket.

2. An adjustable shade-bracket provided with an arm having a slot, a fastening device arranged in the slot, and a cam-lever pivoted on the fastening device and having a substantially wedge shaped head arranged to be turned transversely or longitudinally of the slot to clamp and release the bracket.

3. An adjustable shade-bracket provided with aslotted arm having projecting edges at opposite sides of the slot, a cam-lever provided with a head bent to form an approximately wedge-shaped portion, and a pivot passing through the head and through the slot of the arm, whereby the head is adapted either to extend into the slot or engage the arm at opposite sides of the same.

4. An adjustable shade-bracket provided with an arm having a slot, a lever provided at one end with a head having an approximately wedge-shaped portion, and a pivot passing through the head and through the slot of the arm to permit the head to be turned longitudinally or transversely of the arm, said lever being disposed longitudinally of the arm when the headis in engagement with the same.

In testimony that I claim the foregoing as my own I have hereto aifixed my signature in the presence of two witnesses.

CHRISTIAN HEILRATH.
