CURTAIN -ROLLER.

Specification of Letters Patent.

Patented Jan. 2,1912.

application filed March 21, 1910. Serial No. 550,583.

a citizen of the United States, residing at Coatesville, Chester county, Pennsylvania, have invented certain new and useful Improvements in Curtain-Rollers, of wh ch the following is a specification.

The object of my invention is to provlde a novel; simple and efiicient curtain roller formed principally of sheet metal and havbe=shortened or lengthened as desired; secondly, whereby the roller may be supported to rotate in suitable brackets; thirdly, whereby one end of a shade or curtain may be readily attached to or removed. from the roller; fourthly, whereby the various parts of the roller maybe held in proper relation to each other; .and fifthly, whereby the roller may be actuated by a spring controlled means. 'With the object thus generally stated the invention will be hereinafter fully described and particularly pointed out in the claims.

In the drawings :Figure 1' is a front view of my improved roller. Fig. 2 is a. front view of the upper end of a shade or curtain adapted to be attached to the roller. Fig. 3 is an edge view enlarged of the shade shown in Fig. 2. Fig. 3 is an end view of the strip of metal detached from the edge of the curtain. Fig. 4 is a view of the right hand end of the roller shown in Fig. 1, having the shade shown in Fig. 2 applied to the roller. Fig. 5 is a perspective view of one of the end heads of the roller and the 'adjacent parts ofthe spring actuated means for rotating. Fig. 6 is a longitudinal section through the roller. Figs. 7, 8, 9, 10 and 11 are transverse sections of the roller on lines 7-7, 88, 9-9, 10-10 and 1111, respectively, of Fig. 6. Fig. 12 is a view of parts of the spring actuated mechanism forthe surrounding the other end of the body section. The end section 3 is secured to the body section 2 by soldering or other means .and the end section 4 is adapted to slide upon the body section 2 in a manner to in crease or decrease the length of the roller as desired.

The body' section 2 is formed of sheet metal bentinto substantially tubular form bringing its longitudinal edges adjacent each other and forming a slot 5 therebetween. The longitudinal edges of the body section 2 are bent inwardly and clenched upon the longitudinal edges of a separate sheet metal strip 6 which is bent to form an undercut groove 12 in the body section 2, as shown. The end section 4 is formedof sheet metal bent into substantially tubular form around the body section 2 and having formed therein an undercut groove 13, the metal forming the same being fitted to and adapted to. slide within the undercut groove 12 of the body section 2. The longitudinal edges of the end section 4 are bent to overlap and embrace each other and are clenched together as at 14 forming a seam. The body section 2 has bent or formed there- -in a longitudinal groove 15 to accommodate the seam 14 so that the outer face of the end section 4 may be made smooth. The end sec tion 3 is formed of sheet metal bent into substantially tubular form around the body section 2, the longitudinal edges being bent inwardly around the edges of the body section 2 as shown in Fig. 7. The outer end of the end section 4 is provided with an end head ltihaving an inwardly extending peripheral flange 17 which is inclosed bv the end section 4. The inner end of the flange 17 abuts against the part of the section 4 of the end section 4 forming the seam 14 which parts terminate inwardlv of the end of the section 4 as shown in Fig. 6. The outer end of the end section 4 is bent inwardly over the outer end of the end head 16 thereby firrrly holding the end head in place as clearly shown in Fig. 6. The end head 16 is provided with an undercut opening 18 therein which is in registry with the undercut groove 13- and which forms in effect a continuation thereof.

From the foregoing description it will be seen that the undercut opening 18 and the

undercut grooves

12 and 13 form in effect a continuous undercut groove extending longitudinally of the roller and open at one end.' This continuous groove is adapted to receive one end of a curtain provided with a metal strip which I shall now describe,

forming the undercut groove 13 and parts referring to Figs. 2, 3 and 4. 19 designates the upper portion of a curtain and 20 a metal strip secured thereto. The

longitudinal edge portions

22 and 23 of this strip of metal are bent toward each other, one edge portion 23 being inclose'd between the other edge portion 22 and the body of the strip 21. This bent strip of metal is en aged with one end of the curtain 19 by having one end of the curtain 19 folded and inserted between the body 21 of the strip and the outer edge portion 22 thereof in a manner to have the folded end of the curtain embrace the inner edge portion 23 of the strip of metal, as clearly shown in Fig. 3, thereby holding I the end of the curtain and metal strip 20 in secured to the body section 2.

positive engagement with each other. The outer edge portion 22 of the strip of metal 20 is made narrower than the inner edge portion 23 thereof so that the curtain 19 may extend substantially at right angles from the central portion of the entire strip of metal 20 when the same is inserted in the groove in the roller shown in Fig. 4. This metal strip with the end of the curtain engaged therewith is adapted to be inserted longitudinally of the roller into the opening 18 in the end head 16 and into the

undercut grooves

12 and 13 of the sections 2 and 4 respectively. The dimensions of the bent metal strip 20 and the dimensions of the undercut groove in the roller issuch that when the end of the curtain carrying the strip. of metal has been inserted therein it cannot be removed therefrom laterally of the roller through the undercut groove, but can only be removed longitudinally of the roller and through the opening in the end head 16 thus preventing any liability of accidental disengagement of the curtain from the roller when in operation.

The end sections 3 and 4 of the roller are of substantially equal diameter to engage the outer edges of the curtain and insure its uniform winding upon the roller as will be readily understood. The roller is provided with a suitable spring actuated rotating means which I shall now proceed to describe.

Extending centrally through the outer end of the body section 2 of the roller is a shaft 24 the inner end of which extends into an opening in a block 25 located within and Located within the outer end of the shaft 24 and secured thereto is the inner portion of a pin 27 the outer portion of which extends centrally through and beyond an end head 28 for'the endsection 3. This end head 28 is secured to the end section 3 and bod section 2 as will be hereinafter describe and the pin 27 and shaft 24 are fitted to the end head 28 and block 25 in a manner to permit the entire roller to be rotated independently of the shaft 24 and its pin 27.

Arranged within the outer pro ecting end of the end section 3 and against the outer end of the body section 2 is a disk 29 which is provided with an inwardly projecting collar 30 surrounding the shaft 24. The 1nner face of this disk 29 is provided with pro-. jecting arms 31 which are engaged by one endo a torsion spring 32 surrounding the collar 30 and shaft 24 and having its other end engaged with the'shaft 24 by being extended into a transverse slot 32 therein. The disk 29 is provided with an opening 33 into which the bent edges of the end section 3 extend in a manner to engage the wall of the opening 33 and cause the disk 29 to 'rotate with the roller.

Arranged against the outer face of the disk 29 is a disk or member 34, the outer face of which is engaged by the inner edge of a flange 35 projecting from the end head 28 in a manner to hold the end head in spaced relation to the member 34. The flange 35 is provided with an opening or notch '35 to receive the inturned edges of the end section 3, as shown. The outer end of the end section 3 is bent inwardly against the outer face of the end head 28 to firmly hold or clamp the end head 28 and

disks

29 and 34 between the outer end of the body section 2 and the inturned edge of the end section 3. Extending from the member or disk 34 into the space within the flange 35 are two pairs of

flanges

36 and 37, which extend tangentially with respect to the shaft 24 and which form

pockets

38 and 39. Within each

pocket

38 and 39 is arranged a ball 40, each' ball 40 being adapted to roll within its pocket toward and from the pin 27 of the shaft 24. The pin 27 is provided with acollar 41 arranged between the

pockets

38 and 39 and the collar 41 has notches cut therein, forming teeth 42 upon the collar. The balls 40 are adapted to engage the teeth 42 of the collar 40 and the

flanges

36 and 37 of the member 29 in a manner to prevent the rotation of the member under certain conditions as will be hereinafter explained. The disk or member 34 is provided with an opening 43. therein, the walls of which are engaged by the inturned longitudinal edges of the end section 3 to cause the rotation of the member 34 with the roller.

The outer end of the pin 27 of the shaft 24 is flattened andis adapted to be inserted into the slot of a bracket of well known construction in the curtain fixture art, which bracket is adapted, as'is well known, not only to support the outer end of the shaft 24 but also to prevent the rotation thereof by the engagement of the flattened end of the pin 27 with the walls of the slot in the bracket. The end head 16 is provided with a projecting pin 44 which is adapted to be inserted into an opening in a bracket which is also of well known-construction in the curtain fixture art. Thus the two ends of the curtain. roller may be so that the pins 27 ported by the pins and 4% when the rol er is in operation.

The operation is as follows :Assuming and 44 are supported by suitablefixtures as previously described, it will be seen that the roller may be rotated and that the shaft 24 will remain stationary. The curtain 19 is so wound upon the roller that in lowering or unwinding the curtain from the roller, the roller will be turned in the direction of the full line arrow in Fig. 11, and the spring 32 will. be wound upon the shaft 24. After the curtain has been unwound or lowered to the desired extent and is released, one of the balls 40 will roll into one of the notches in the collar 41, and will be engaged by one of the teeth 42 of the collar and onset the

flanges

36 or 37, in a manner to lock theroller in position upon the shaft 24 and prevent the action of the spring 32 from rotating the roller to rewind the curtain thereupon. When it is desired to permit the spring 32 to rotate the roller and rewind the curtain, the curtain is first drawn downwardly against the action of the spring and is then permitted to move upwardly with such speed that it will permit the spring 3240 rotate the roller with sufiicient speed and maintain the balls 40 in the outer portions of the pockets 88 and 39 and prevent. the engagement of the balls 40 with the teeth 42 of the-collar 41 until the curtain has reached the desired position, whereupon, by retarding the movement of the curtain, the speed of the roller being turned by the spring 32 will be decreased sufficiently to permit one of the balls 40 to reengage one of the teeth 42 and prevent the further rotation of the roller by the action of the spring as previously explained.
