UNITED STATES PATENT oFFrcE.

ERNST ENGSTFELD, OF JERSEY CITY, NEW JERSEY,-

WINDOW-SHADE FDITURE.

Be it known that I, ERNST Exos'rrnu), a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented new and useful Improvements in Window-Shade Fixtures, of which the following is a specification.

This invention relates to window shade fixtures. 1

The object of the invention is to provide an article of this character which may be readily attached to a window casing and be easily detached therefrom without marring or 111 any way injuring the'casing; which shall be capable of a novel and extended range of adjustment, whereby one set of brackets may be utilized for supporting many lengths of shade rollers; and which shall be simple of construction, eflicient and durable in use, and cheap and easily manufactured.

\Yith the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the 'novel construction and combination of parts of a shade fixture, as will be fully hereinafter described and claimed.

In the accompanying drawings forming a part of this specification and in which like characters of reference indicate corresponding parts, Figure 1 is a view in front elevation of a portion of a window casing showing one of the shade fixtures attached thereto. Fig. 2- is a vertical transverse section through the fixture. Fig. 3 is a perspective detail view of one of the roller bracket-s.

In illustrating the invention, but one of the fixtures is shown, that on the right-hand side of the window casing, that on the lefthand side being a counterpart, except that the disposition of certain of its parts is transposed.

The fixture embodies a bracket support designated generally 1 and a. roller bracket designated generally 2. The bracket support which may be formed of a single piece of; metal cast or stamped to the appropriate shape, or constructed of two or more pieces of metal suitably assembled, comprises an attaching plate 3, a rack bar 4: and two Specification of Letters Patent. Application filed October 22, 1907. Serial No. 398,633.

Patented Aug. 11, 1908.

once to Fig. 1, the right-hand sides of the teeth are rounded and the left-hand sides are straight, the reason for this arrangement being hereinafter explained, it being understood that the teeth of the right-hand bar are the reverse of that just described.

The roller bracket may be cast or be stamped to shape and comprises the usual arm 7 having an orifice 8 to receive the pintle of the shade roller, a bearing plate 9 disposed at right angles to the arm, a guard 10 and a keeper or do 11 carried by a lip 12 extending at ri ht ang es to the bearing plate 9. The guarr is disposed at the lower edge of the bracket and at the point of juncture of the arm and bearing plate, is carried by the latter, and is rearwardly and upwardly bent to embrace the lower upwardly beveled edge 13 of the attaching plate, the coaction between the two parts operating in a positive manner to prevent the loosening of the bracket should the curtain pull string slip from the hand of the operator and thus allow the eurtain to wind up violently and without re straint upon its roller. The upper edge of the arm is provided at its point of juncture with the bearing plate 9 witha slot 14 that is designed to straddle the rack bar and thus 7 increase the stability of the assemblage be tween the parts. The dog 11 is carried by the upper edge of the bearing plate diagonally opposite the guard and is designed to engage with the teeth of the rack bar to hold the bracket at any desired adjustment.

Intermediate of the ends of the bracket support and in its upper outer portion is a deression 15 over which and in the lower edge of the rack-bar is a recess 16, the function of these two parts bein to permit assemblage of the bracket with the support. This is effected in the following manner: The dog is assed through the recess to the rear of the rack-bar, the bracket being held at an an le to the face of the supporting plate for his purpose. This will brmg the rack-bar into the slot 14 and upon the bracket being moved to the left until the slot will enter the recess, the bearing plate will be moved into contact with the supporting plate, whereupon the dog will engage the rack teeth and the guard the under edge of the supporting plate. The supporting plate is secured to the window casing by screws 17 three in this instance being shown which will permit of the supporting plate being readily positioned or removed as required and without injuring the window casing.

When the shade roller is to be hung the gfpintles are en aged as usual in the bracket orifices and tie brackets are adjusted as requisite. Owing to the weight of the our tam. the dogs will be caused to bear against the straight faces of the teeth and thereby be the attachin late and a do to en a e the v D Y D D D rack-bar.

2. A window shade fixture comprising an attaching plate provided with terminal stops, a rack-bar secured to the stops and spaced from the attaching plate to provide a guideavay, a roller bracket having a bearing late to engage with the attaching plate and .iaving a guard to engage with the rear side of the attaching plate, and a dog to engage wit-h the rack-bar.

3. A window shade fixture comprising an attaching plate, a rack-bar spaced therefrom to )rovide a guide-nay, a roller bracket provided with a bearing plate to engage with the attaching plate, a guard carried h the bracket and engaging the rear face of t 1e at:

taching plate, a lip projecting from the bearing plate, and adog carried by the lip to engage with the rackbar.

4. A window shade fixture comprising an attaching plate, a rack bar carried thereby and spaced therefrom to provide a uide-way, a roller bracket having a bearing plate to roject through the guide-way, a do" carried by the bearing plate to engage with the rackbar, and a guard carried by the bracket to engage with the rear side of the attaching plate.

5. A window shade fixture comprising an attaching plate havin its lower edge rearwardly beveled, a rac '-bar carried thereby and spaced the refrom to provide a guide-wa a roller bracket provided with an angularly disposed guard to engage the beveled edge of the attaching plate and with a dog to engage the rack-bar, and means for limiting lateral movement of the roller bracket relatively to the attaching plate.

. 6. A window shade fixture comprising an attachingplate having its lower edge rearwardly beveled, a rack-bar carried by the attaching plate and spaced therefrom to provide a guide-way, a roller bracket having a bearing )late to project through the uideway, ant a slot to straddle the rackar, a

guard carried bythe bracket to engage the beveled edge of the attachin plate, and a dog carried by the bearing p ate to engage with the rack-bar.

In testimony whereof, I aifix my signature in presence of two witnesses.
