ROLLER-CURTAIN GUIDING AND LOCKING DEVICE.

App1ication filed February 6, 1922. Serial No. 534,548.

Improvement in Roller-Curtain Guiding and Locking Devices, of which the following is a full, clear, and exact description.

My invention relates to improvements in roller curtain guiding and locking. devices for roller porch curtains or the like, and it consists in the combinations,constructions, and arrangements herein described and claimed. 7

An object of my invention is to provide a roller curtain guiding and locking device which is adapted to positively lock the roller from a vertical or a rotative movement.

A. further object of my invention is to provide a device of the type described which holds the unrolled portion of the curtain taut, thus preventing any flapping thereof.

A further object of my. invention is to provide a device of the type described which is adapted to be secured to any roller curtain without altering the construction ofthe latter.

A further object of my invention is to provide a device of the type described which makes use of but a single guiding wire on g each side thereof.

A further object of my invention is to provide a device of the type described which is adapted to positively lock the curtain roller in adjusted position, thus doing away with the necessity of tying the cords which raise and lower the roller.

A further object of my invention is to provide a device of the type described which is simple in construction, consists of a minimum number of parts, and which is not likely to easily get out of order.

Other objects and advantages will appear inthe following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which- Figure 1 is a front elevation of the device as shown operatively applied to the upper posed in openings and lower beams of a porch orthe like,

ings 17"therein,

Figure 4; is a perspective detail view of the members 13 and 19 shown in dismantled relation. V

In carrying out my invention, I make use of the ordinary, transverse members or beams land .2, to which I secure vertically extending guide wires 3 and 4. A roller curtain of ordinary type which comprises a roller 5 and a curtain 6,

has its. free ends secured to the inner side of the member. 1 by'means of 'tacks'7, or the like. To each end of the roller 5 I secure, by means of screws 8, a tapered pinion 9. As clearly shown in Figuresl and 2, the pinion-9 is provided with a flange 10, which is disposed adjacent, to the end of the roller 5; and'is also provided with a bore 11 which communicates with a recess 12 for a purpose hereafter described. A guide member 13 has a stub shaft ll which is disposed inthe bore 11, and which is upset atitsin ner end so as to grip a washer 15. This construction preventsv the movement of the member 13 inan axial direction with respect to the pinion 9. The member 13 is also pro-- vided with a circular portion 16, on the face of which thepinion 9 is adapted to rotatively engage. V 2

The members 13 are provided with openthroughwhich the wires 3 and 4c areadapted to GXtQIldx As clearly shown in Figure 2, the members 13 have outwardlyprojecting lugs ls'against which'the wires 3 and l are adapted-to lie. then provide a means by which the roller 5 is prevented from rotating or from moving along. the wires 3 and 4. This means comprises a clamping member 19 which has sides 20 that are adapted to straddle thebody portion of the member 13.;

The ends of the sides 20" iii) are adapted to engage with the wires 3 and 4, and to force the latter against the lugs 18 so as to prevent movement of the member 13 with respect to the wires. The members 19 are also provided with a tooth-shaped member 21 which takes the place of a pawl,

and is adapted to engage-with the pinion 9 so as to preventlrotation thereof with re spect to the member 13. The members 19 areope'ratively secured to the members 13 bymeans of wing bolts 22 which' are dis- 23 and 2a inthe members 13 and 19, respectively. "It will thus be seen that a slight; rotation of the wing nuts 22 will cause the members 19 to movetowardthe members 13 so as to'positively grip the wires 3 and 4 and to engage the pinion 9 to prevent the rotation thereof.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The curtain roller is provided with the ordinary cords which are adapted to raise or lower the roller in the ordinary manner. The cords 25 are disposed adjacent to each side of the curtain 6 and are secured at one of their ends to eyelets 26 which are carried by the member 1. The cords are then passed down and around the roller 5, are passed through the eyelets 26, and are then passed through an eyelet 27, from which they hang clownwardly so as to be readily grasped by the operator.

When the curtain is desired to be raised, the wing nuts 22 are rotated so as torelease the wires 3 and 4 and the pinions 9 from the members 19. The curtain is now free to be raised. The cords 25 are pulled, which in turn rotate the roller and cause the roller to move'upwardly, and at the same time to wind the curtain 6 thereon. in the ordinary case, the cords would have o be tied at their free ends so as to prevent the unwinding of the roller 5. In my present device, however, the wing nuts 22 are tightened so as to cause the members 19 to positively grip the wires 3 and 4 to engage with the pinions 9 so as to prevent the rotation of the pinions. It will therefore be seen that the roller 5 is positively clamped in position, and is prevented from move ment along the wires 3 and 4. Furthermore, the roller 5 is prevented from rotation, since the portions 21 of the members 10 engage with the pinions 9, and prevent the rotation of the pinions 9 with respect to the members 13. If a gust of wind should strike the curtain 6, the curtain would not flap, since it is held taut by the roller 5. In the ordinaryroller, if a gust of wind shouid strike the curtain 6, the curtain would unwind from the roller 5, even though the rollcr was held in a fixed position. In the present device, however, this is obviated, since the roller 5 is positively prevented from rotation and therefore cannot feed any more of the curtain G to the unwound portion of the curtain. The'extended portion of the curiain 6 will act as a rigid wall.

The device is very simple, and consists of a minimum number oi parts. It may be readily applied to any curtain roller without altering the construction of the lat ter. It is obvious that the device provides a positive means for preventing the rotation of the roller, or of the movement of the roller in a vertical direction. The device is durable and efficient for the purpose intended, and is not likely to easily get out of order.
