Specification of Letters Patent.

Serial No. 405,423.

T o all whom it may concern:

Be it known that I, EDWARD I-I. MoCLoUD, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Supports for Rolling Curtains or Shutters, of which'the following is a speciiication.

The object of this invention is to provide improved means for compensating for the diminution or increase in the size of the roll of a curtain so as to keep the unrolled portion substantially tangent to the roller and therefore facilitate the movement oi' the curtain in a channel.

The invention is embodied in the improved construction hereinafter described and claimed for permitting the roller to move laterally as the curtain is wound and unwound, theinvention not being confined in its practical application to the forms and proportions shown in the accompanying drawings.

In said drawings-Figure 1 isa view in elevation of the right-hand end bracket containing the invention; Fig. 2 is a horizontal section on the line :r- Fig. l; Fig. 3 is a similar section of the left-hand bracket, Fig. 4 is a fractional view showing the assembled parts in connection with a curtain g Fig. 5 is a vertical sectional view.

In the views 1 and 1a designate end brackets upon which can be secured a suitable hood if desired. These brackets are provided with slots 1b and 1C parallel to each other and slightly inclined to the horizontal and from the outer portions of the brackets inwardly.

2 designates the curtain roller, and 13 the curtain attached thereto, said roller having suitable studs or bearings at its opposite ends. These studs or bearings project through the slots 1b and 1c of the end brackets and enter

carrier bars

3 and 3 at the outer sides of the brackets 1 and la. The carriers 3 and 3a are supported by means of the limbs or

links

4 and 4a and 5 and 5, all of substantially equal length, the.

links

4 and 5 being pivotally attached to the upper portions of the outer sides of the brackets and to the inner ends of the carrier bars 3 and 3a, and the links 4a and 5L being pivotally attached to or supported on rests at the lower portions of the outer sides of the brackets beyond the carriers, and to the outer ends of the carrier bars 3 and 3a, so that when said links are swung the intermediate points of the carrier bars, where the bearings are supported, will move in a substantially straight line inclined from the outer portions of the brackets inward. The aim of this construction is to secure a normal tendency of the roller and curtain to gravitate or press laterally inward. By reason of this tendency to inward move ment the unrolled portion of the curtain, while being wound or unwound, can be kept substantially tangent to the edge of the roll while in the channel, the mouth of which is in the plane indicated by the character 15 Fig. 5. Cooperating with and resisting the inward pressing of the curtain and its roller, and to maintain the curtain in a position tangent to the roll while in the channel, is a roller device or bearing comprising a rocking bracket-arm 6 pivoted at its middle in the rear of the hood, and containing at its opposite ends anti-friction rollers 6a and 6b against which the curtain bears. The mounting of the rollers 6a and 6b on the rocking bracket-arm permits the device to accommodate itself to the changing form of the surface of the curtain, especially when it is of the slatted variety, at the place where it passes the device.

The means for operating the curtain comprises a large spur gear 7 secured on the outer end of the right-hand stud journal of the curtain roller, as seen in Fig. 1, a pinion 8 journaled on a pin 9 projecting from an eX-A tension 3b of the carrier bar 3, a sprocket wheel 10 also on the pin 9 and turning with the pinion 8, and a sprocket chain 11 running over the sprocket Wheel 10. The pin 9 can be further supported by a bracket 12 secured to the extension of the carrier bar 3 and to the stud journal -of' the curtain roller. It will be observed from this construction that the mechanism for operating the curtain moves with the roller and curtain.

It will be .observed that, in the instance shown, where these

links

4, 4a and 5, 5a engage the bearing carriers they move in oppositely-curved arcs of circles and consequently cause the bearings and roller to move in substantially a straight line laterally;

The curtain 13 is depicted as being of wood, but I do not know of any reason why my invention cannot be used in connection with other constructions of curtains.

Lugs on the bearing carriers, as indicated at 16, 16a, to engage the end brackets, can be employed to prevent longitudinal disturbance of the roller with. reference to the brackets.

What .I 'claim and desire to secure by Letters Patent is:

1. In combination with a curtain roller and curtain, of means for supporting the same comprising brackets, carriers to receive the bearings of the roller, and swinging supports pivotally connected .to each of saidV carriers, said supports being pivoted to swing laterally with reference to the roller and adapted to guide the latter in substantially a straight line.

2. In combination with a curtain roller and curtain, of means for supporting the same comprising brackets, carriers to receive the bearings of the roller, and swinging supports for each oi said carriers, said supports being pivoted to swing laterally with reference to the roller and adapted to guide the latter in substantially a straight line inclined to the horizontal.

3. Means for supporting a curtain roller and curtain thereon, comprising, in combination, brackets, means forming channels for the curtain, carriers to receive the bearings of the roller, and swinging supports for each of said carriers adapted to permit the bearings to move in a substantially straight line inclined to the horizontal and downwardly toward the channels.
