CURTAIN SHADE ROLLER Original Filed Feb. 8, 1919 2 Sheets-Sheet 2 Reiaued Nov. 26, 1929 UNITED STATES PATENT OFFICE CECIL A. DANIEL, OF GREENSBORO, NORTH CLROLINA, ISSIGNOR 'I'O CUNNINGHAM SPRINGLESS SHADE COMPANY, OF GREENSBORO, CAROLINA, A CORPORA- DION OF N ORTH CAROLINA CURTAIN-slum nonfinn Original application filed February 8, 1919. Serial Not-27am! neniewmimu' L; 1991-", serial No. 477,864. Original No. 1,404,837, dated January 31, 1922. Application on mime filed August 1, 1925. Serial My invention relates to an improvement in curtain shade rollers, and the means for raisin and lowering the same.

is invention is an improvement on the 5 construction disclosed in Letters Patent to Dawson, No. 1,181,852, dated May 2, 1916, on

which Reissue Patent No. 14,37 5 was granted I -2 or pulley constructed and adapted to cooperate with its support to receive and guide the curtain-raising and lowering cord in both the raising and lowering operation, and so automatically pinch or clamp the cord be- I tween itself and its su port when the curtain reaches the desired ad uStment.

In the accompanylng drawings Fig. 1 is a view in perspective;

Fig. 2 is a longitudinal section through the a bracket, the end of the roller, and the pulley on the line 2-2 of Fig. 1;

Fig. 3 is a section on the line 33 of Fig 2, taken at right-angles to Fig. 2;

Figs. 4 and 5 are sections on the lines 4-4. and 5-5 of Fig. 2, showing the stop pulley in difl'erent positions with respect to the curtain raising and lowering cord;

Fig. 6 is an end View;

Fig. 7 is an enlarged View of the pulley in the position shown in Fig. 2, with only a fragment of the bracket showing.

A, represents a roller, and 1 is a reel at the left-hand end thereof, within which the cur- 5 tain raising and lowering cord 2 is secured and reeled. The pintle 3 at the end is preferably round and turns in a correspondinglyshaped hole 4 in the arm 5 of the bracket 6, which supports the end of the roller, and

80 the pintle 7 at the opposite end turns in an open slot 8 bymeans'of which the roller and shade may be lifted and removed: from the bracket. 'l hebrack et preferably hasan overhanging arm 9 which: terminates in proximity to'the reehand, in the-particular form shown, a little over and beyond the vertical plane of the-pintle 3: The stop-pulley 10 is rotatably mounted on a pin 11 secured at theends in the ears of the overhanging arm 9:

This stop-pulley has three grooves therein, the main-circumferential groove 12 of uniform depth at' oneside'and the two switchooves Band 14 extending spirally thererom-and-of gradually decreasing depth until they reach nothing at thecyli'ndrical surface ofthe pulley, the function of which is to receive and pinch the curtain-shade raising and lowering cord 2' betweemthe'pu-lley and tfiie'adjaoentvsurfaoe of the overhanging arm of thebracket when it" is desired. to stop and hold the curtain-shade at the elevation desired. 'Fhis'is accomplished by pulling-the cord slightly to the rightand slackening the pulley, whereupondt isswitched into one of the'spinal grooves and caught between its shallowend and the" arm of the bracket Where it is'wedged'and held (the weight of the cumin co operatinga to tighten and: perfeet; the fastening) until again pulled, whereupon: the cord automatically switches back into the main circumferential groove 12, Where it is held while the curtain is being either raised or lowered until'it is again d'esired to" fasten it. Then the cord is pulled slightly totheright' and allowed to slack, it immediately becoming pinched and caught or wedged in between the spiral groove in which'it he's and the adjacent surface of the bracket-arm In this way; a: simple automatic device is provided allin one'attachment at the point where the curtain-shade roller is held, thus dispensing with any other fixture or fastening common in the springless curtain shades for fastening the cord.

I have described the foregoing as an illustrative type of my invention, although con scious that it is susceptible of modifications, and it is my desire to so cover the invention that it will comprehend all legitimate forms involving the principles set forth.

' I claim: i

1. A device of the character described ineluding a curtain-shade, and a roller, having a round pintle, and provided With a reel at one end and a cord attached to the reel'and adapted to wind thereon, and-a bracket hav ing an integral bearing formed to fit the pintle of the roller and a pair of integral ears in planes parallel With the bearing, a stop-pulley rotatably mounted in said ears to turn on an axis parallel with the axis of the curtain-shade roller, said stop-pulley having grooves therein, and between which and the bracket the cord on the reel extends, certain of said grooves being adapted to guideand clamp the cord, the curtain and cord being wound around the roller and reel in 2Q opposite directions, the cord being wound to roll up the curtain, and the curtain being unrolled by releasing and slackening the tension of the cord. v

2. The combination with a curtain-shade roller and a curtain-shade and cord, said shade and cord secured to and adapted to wind thereon in opposite directions, of a bracket or fixtureforming a bearing for the roller and a guide, for the cord, located above the roller, and rotatable means carried by the bracket to which the cord extends directly from the roller, and between Which and the bracket the cord passes :and is adapted to be pinched when directed laterally to a predetermined osition thereon, the cordvbeing free and isconnected from the point Where it leaves the rotatable means, so that its manipulation is at all times entirely within the control of the operator. I 4o '3. The combination with a curtain shade roller and a curtain shadeand cord, said shade and cord secured to and adapted tov wind thereon in opposite directions, of a bracket or fixture forming a bearing for the roller and a guide for the cord, and rotatable means carried by the bracketto which the cord extendsdirectly from the roller, and between which and the bracket the cord passes and is adapted to be pinched when directed. laterally to a predetermined position thereon, the cord being free and disconnected from the point where it leaves the rotatable means, so that its manipulation is at all times entirely within the control of the operator.

In testimony whereof I affix my signature. I CECIL A. DANIEL.
