This invention relates to curtain-operating apparatus, and more especially it relates to apparatus for opening and closing a pair of curtains, portieres, drapes or the like, that 'are supported at the top and are movable toward and away from each other.
The invention is of especial utility for operating the curtains oi theatres or the like, wherein the curtains in extended or closed position overlap at the center of the proscenium, and in the opening .or withdrawing operation they gather only at their remote end portions, which portions may be concealed from the audience.
The chief objects of the invention are to provide an improved supporting frame for the apparatus; to provide improved track-travelers that operatively engage the operating cord when the latter is moving in one direction only; and to obviate the use of extraneous means, such as cams and the like, for causing the travelers operatively to engage the cord, or to become disengaged therefrom. Further objects include reduced initial cost and lower maintenance costs. Other objects will bemanifest.

Figure 5 is a vertical longitudinal section of the apparatus, at one end thereof, showing one series of curtain-supporting travelers moving to curtain-opening position;
Figure 6 is a section on the line 6-6 of Figure 1 and Figure 4; T
Figure 7 is a section on the line 1-1 of Figure 9;
Figure 8 is a section on the line 8-8 of Figure 5; and
Figure 9 is a vertical longitudinal section of the apparatus, similar to Figure 5, but viewed from the opposite side of the apparatus and at the opposite end thereof, showing the other series of travelers moving to curtain opening position.
Referring to the drawings, I0 is 'an overhead metallic frame that is tubular in form, generally rectangular in cross-section, and formed throughout with a centrally-disposed longitudinal slot H in its bottom wall, the latter being formed, at 5 each side of said slot, with respective fiat-bottom grooves l2, l2 constituting runways for respective series of wheeled travelers T, T. The latter support the two sections A and B of a curtain, said sections overlapping somewhat at the midl0 dle of the apparatus as is most clearly shown in Figures 1 and 4.
The curtain sections are opened and/or drawn together by means of an operating line or cable l5 that is trained about a grooved pulley is that 15 is journaled upon a vertical axis in one end of the frame in (the right end as viewed in Figures 1, 2, 3, and 5), the cable extending in two parallel reaches the length of the frame, directly over the runways l2 therein. At the opposite end of 20 the frame the cable extends over respective grooved pulleys l1, l1 that are journaled on a horizontal axis, the free ends of the cable extending downwardly to any suitable cable-operating mechanism (not shown).
The travelers T include two master travelers T, T that are disposed over the adjacent or inner ends of the respective curtain sections A and B. As is most clearly shown in Figures 4 and 6, each of said master travelers comprises 0 a relatively long metal plate 19 that has its upper and lower marginal portions bent in the same direction atright angles thereto to constitute marginal flanges. Suitably journaled on the plate-l9, near each end thereof, are respective wheels or rollers 20, 20 that are positioned in a frame groove I2, the arrangement being such that the plate l9 extends through the frame-slot II, the upper flange of the plate lies along the cable l5 below the same, and the lower 40 flange of the plate is disposed in spaced relation to the bottom of the frame. A generally 0- shaped clip 2! lies against the inner face of the plate 89 centrally thereof and extends through. suitable .slots in the respective flanges of said plate, the upper end of clip 2i being hooked over cable l5 and there being a set screw 22 extending through the-bottom portion of said clip and bearing against the under side of the lower plate-flange. By setting up screw 22 the clip 2| is caused to clamp the cable 15 to the upper flange of plate l9 whereby movement of the cable in either direction also moves the master traveler. The curtain sections are attached to the master travelers by respective S-hooks 23 that engage in grommets in the upper margin of the curtain and in respective loops or eyes 24 depending from the lower flanges of plates I9.
As is most clearly shown in Figure 4, the rollers 20 of the master traveler associated with curtain section A are disposed in a different framegroove l2 than are the rollers of the traveler associated with curtain-section B, and since the plates l9 and clips 2| are relatively thin, there is ample room in the slot II for one master traveler to pass the other. The arrangement is such that overlapping of the curtain-sections A and B at the middle of the apparatus is accomplished without the use of separate track and frame structures for each curtain section. Respective stop plates 25 are adjustably mounted by means of screws 26 interiorly of the frame ID in position to obstruct the runway grooves l2, and thereby to provide positive stops for therespective master travelers in the closed or drawn position of the curtain.
The outer or remote ends of the curtain-sections are supported by S-hooks 23 that engage respective loops or eyes 21 that are fixedly attached to the bearing blocks that carry 'pulleys I6, I! at each end of the frame l9. Between the eyes 21 and the eyes 24 of the master travelers the curtain sections are suspended from the respective series of travelers T, which travelers are so constructed as automatically to operatively engage the cable l5 when the latter is moved in the direction to open the curtain, and automatically to release their engagement with said cable after they have reached the limit of their travel. Since the respective series of travelers engage respective reaches of the cable l5, and said reaches move in opposite directions during operation of the cable, the travelers require to be in reversed relationship according to their series, but all travelers T may be identical.
Each traveler T comprises a plate 29 carrying a laterally projecting stub shaft 39 upon which is journaled a roller 3| that is disposed in a frame-groove l2, the said plate extending through slot H of the frame l0 and being supported by said roller. The-lower margin of the plate '29, below the frame, is bent laterally to form flange 32 that carries a depending loop or eye 24, an S-hook 23 being suspended in the latter for attachment to a curtain-section.
Swivelled on the stub shaft 30 is a device for releasably connecting the traveler T to the cable l5, said device comprising a pair of legs 33 that straddle roller 3| and at th eir juncture are integrally formed with a cable-engaging structure consisting of an annular thimble 34 through which the cable 15 passes, and a horizontal lip 3 spaced somewhat from the thimble 34, and in contact with the under side of cable IS. The thimble 34 is somewhat larger than the cable so that the latter passes' freely therethrough, and has a rolled or flared margin on the side nearest lip 35. The thimble 34 and lip 35 are so arranged that the lip trails the thimble during the opening of the curtain, that is, when the traveler is moving toward the end of the frame l9.
Struck out from the upper margin of plate 29 is a lug 36 which limits the pivotal movement of the cable-engaging structure in one direction, the cable [5 limiting its pivotal movement in the opposite direction. The lateral margin of plate 29 that is remote from the end of the frame [9 is locally bent to form a flange 31, and when the travelers T are in laterally abutting relation the said flange 31 on each traveler will abut a leg 33 of the cable-engaging structure of the adjacent traveler to hold said structure in upright position, in which position the axis of thimble 34 is horizontal. Suitable fixed abutments 38, 38 at the'respective ends of frame l0 serve the same purpose as flanges 31 in engaging and tilting the cable-engaging structures of the travelers at the outer ends of each 'seriesof travelers.
In the operation of the apparatus, assuming the curtain to be in closed position as shown in Figures 1 and 4, the curtain-sections A, B will be in overlapping position and the travelers T will be uniformly distributed lengthwise of the frame I0. Opening or withdrawing of the curtains is accomplished by operating the cable I5 in the proper direction so that its respective reaches move in the direction, indicated by the arrows in Figures 4 and 9, it being understood that said reaches move in opposite directions. This movement of the cable so tilts the cableengaging structures of travelers T at an angle to the cable that lips 35 of said structures are drawn upwardly against the cable with sufiicient force frictionally to grip the cable and slightly flex it as shown, with the result that there is no farther relative movement between the cable and travelers T and said travelers move along with the cable in properly spaced relation. Master travelers T being normally fixed to the cable also travel with it, and pass each other on their respective trackways as the curtain-sections move apart. With the cable firmly gripped by all of the travelers, it will be apparent that the curtain sections will move apart without any substantial gathering between travelers.
As each traveler T at the outer end of each series of travelers approaches the end of frame I0, its cable-engaging structure engages the abutment 38 thereat whereby said cable-engaging structure is forced into upright position, with the result that its lip 35 releases its grip on the cable and the latter is permitted to move freely through the thimble 34 of said structure. With the outermost traveler T motionless, the curtain begins to gather as the adjacent traveler approaches the motionless one. The said adjacent traveler ceases moving after a leg 33 of its cableengaging structure strikes flange 31 of the motionless traveler whereby said structure is forced into upright position and thus releases the cable. This operation is repeated until the curtain is fully open and the master traveler T abuts the nearest traveler T.
When the directionof movement of the cable I5 is reversed to draw the curtain-sections together in overlapped relation, the pull on the cable draws the master travelers T toward the middle of the frame l0, said master travelers carrying the curtain sections with them, the cable sliding freely through the thimbles of the travelers T. As successive portions of the curtainsections become taut they pull successive travelers T along with them, the cable-engaging structures of the travelers being inoperative at this time because the direction of movement of the travelers, and because the latter and the cable are moving at the same speed.
The invention provides an improved curtainoperating apparatus that is superior in construction and operation, and which achieves the several advantages set out in the foregoing statement of objects.
