Definitions

  • the present invention relates to novel apparatus for pleating and stretching draperies and positioning them for folding and finishing and more particularly relates to such apparatus employing a pair of spaced-apart upright posts or channels with a horizontal hanger bar for engaging the upper end of said draperies, extending between said channels and a horizontal pleater bar assembly extending between said channels below said hanger bar for clamping the lower end of the draperies so that they can be stretched in a pleated condition by elevating the hanger 'bar.
  • Apparatus for pleating and stretching draperies between a pair of drapery engaging members vertically movable relative to each other between a pair of upright channels has been previously proposed. Such apparatus, however, has been found unsatisfactory from several aspects, such as in the means for locking the lower member or pleater bar in gripping engagement with the lower end of the drapery, in the means for releasably attaching the upper end of the drapery to the hanger bar, in the means for vertically manipulating the hanger bar, and in the means of moving the pleater bar assembly vertically along the channels. Drapery pleating and stretching apparatus as proposed heretofore, has also been relatively complex and costly. Apparatus of the type under consideration is used for pleating draperies initially in preparing them for folding and may also be used after the draperies have been cleaned, to stretch and repleat the draperies and position them in a convenient position for banding in the pleated condition.
  • an object of the present invention to .provide an improved drapery pleating and stretching apparatus having a pleater bar assembly for clamping the lower end of said draperies in a pleated configuration so that said draperies may be stretched by elevating the upper portion of said draperies.

  • FIG. 18 is a side elevation of the apparatus shown in FIG. 17.
  • our present invention provides a horizontal hanger bar 86 and a horizontal pleater bar assembly which are vertically movable along vertical, spaced-apart members on channels 11 and 12.
  • Drapery 162 may be pleated and stretched by hanging the upper end to the hanger bar, clamping the pleater bar assembly 160 on lower end of the drapery with the pleater bar asassembly locked against vertical movement along the channels 11 and 12, and elevating the hanger bar 86 by operating the winch 24.
  • a pair of upright channels 11 and 12 with their open sides facing each other, are supported on pedestals 13 and 14 respectively.
  • the upper ends of these channels are tied together by a horizontal tie bar 81.
  • the left upright channel 11 is braced in its veritical position by a diagonally extending front brace 15 and a similar diagonally extending rear brace 16.
  • the right upright channel 12 is similarly braced in its Vertically position by a front brace 15a and a rear brace, not shown.
  • a first or back pleater bar 19 is mounted for limited lateral movement on a rectangular bar 47 Whose opposite ends are respectively attached to the vertical plates 59 and 59a which slidably engage channels 11 and 12 respectively.
  • the pleater bar 19 has a plurality of laterally extending, equally spaced, pleater blades 22 disposed at right angles thereto.
  • a second pleater bar 18 also carries a plurality of pleater blades 21 having the same spacing as the pleater blade 22.
  • These two pleater bars 18 and 19 have a generally comb-like configuration. In the operative position of the pleater bar 18 shown in full lines in FIG. 5, these blades 21 extend toward pleater bar 19, the pleater blades 21 of pleater bar 18 interdigitating with the pleater blades 22 of pleater bar 19.
  • Pleater bar 18 is carried upon a rectangular cross-bar 85 whose opposite ends are respectively attached to the arms 76 and 76a. The opposite ends of these arms are respectively pivoted on members 62 and 62a which extend vertically upward from the sideplates 59 and 59a respectively.
  • the comb-like pleater bar 18 is thus movable in a large are from the operative position shown in full lines in FIG. 3 to the parked position shown in broken lines above the mating pleating bar 19.
  • the pivoted pleating bar 18 may be detented or hooked in its raised or inoperative position in any appropriate manner.
  • the pleater bar 18 may be arranged for movement into the integrated position with pleater bar 19 by means other than the pivot means shown in FIG. 3, as, for example, by horizontally movable means or by detachable means.
  • the pleater bar assembly including both of the mating pleater bars 18 and 19 may be raised and lowered as a unit with the supporting sideplates 59 and 59a which are vertically movable up and down the channels 11 and 12.
  • two pulleys 66 and 66a are rotatably carried in the U-shaped brackets 69 and 69a, respectively. These are attached to the sideplates 59 and 59a, respectively and traverse one edge of the side channel 11. Two other similarly grooved rollers 64a and 66a traverse one of the inner edges of the channel 12.
  • the sideplates 59 and 59a and all the parts connected thereto are indirectly supported by the large eyelets 63 and 63a, FIG. 5, the latter of which may also be seen in FIGS. 7 and 8.
  • Sideplate 59a is secured to plate 60a by the spacer 88 and by the shaft on which lever 23 is pivoted.
  • the entire pleater bar assembly 160 is counterbalanced by a weight in the tube 72 which is secured to channel 11. This weight is attached to the cable 68 which traverses the pulley 74 rotatably mounted at the top of channel 11, the other end of this cable 68 being secured to the ring 63.
  • the cable 28, FIGS. 1 and 5 is connected to the ring 63a which is rigidly attached to the plate 59a, and the other end of this cable, after passing over pulleys 75 and 74, is likewise connected to the counterweight in the tube 72.
  • the draperies that are to be pleated or stretched must be hung, in a manner hereinafter to be described, from the horizontal hanger bar 86 which is vertically movable against the weight of the bar and the draperies in response to the clockwise rotation of the crank 25 attached to the winch 24.
  • a ratchet wheel 27, rigidly and concentrically secured to the winch 24, is releasably held in any adjusted position by means of the pawl 43, (FIGS. 5 and 6) which is pivotally carried on the bracket 45 secured to the upright channel 12.
  • One end of the extension spring 46 is attached to the pawl and the other end of this spring is attached to a pivoted lever 26 whereby this spring may be moved over the pivoting point of the pawl to give it a toggle action in a manner well-known in the mechanical arts and therefore not further described here.
  • the groaved wheels 64 and 66 which are rotatably mounted within the U-shaped brackets 65 and 49 traverse one edge of the channel 11 while the corresponding grooved wheels on the opposite side of the vertically movable assembly traverse the corresponding edge of channel 12.
  • the hanger bar 86 is shown in enlarged view, FIGS. 10-12, and as shown may be an extruded member 114 with a front track member 116 upon which the drapery hook carriage 118 is mounted for lateral or horizontal movement upon the hook or hanger bar 86.
  • the hook carriage 118 is provided with a wheel 120 which may be journalled on the opposite end of the hook wire 122, as best shown in FIG. 11.
  • the hook 110 is connected to the carriage member 118 by fastening the hook wire end 122 through an aperture 124 and is also connected or fastened to the carriage by a crimped portion 126 of the carriage.
  • This firm engagement of the hook to the carriage at two locations provides a firm support for the hook so that the drapes can be removed from the hooks all at once by merely grasping the upper end of the drapery and pulling upwardly.
  • the hook 110 would tend to break away from the carriage.
  • the crimped connection 126 prevents the hook 110 from pulling or moving outwardly from the carriage 118 when the drapery is removed from the hook bar 86.
  • the carriage members 118 are slideable on the track 116 of the hook bar 86 and binding of the carriage as it slides a along the track is prevented at the bottom end of the carriage by rounding at 128 the lower fold or loop 117 which wraps around the lower surface 130 of the track 116.
  • Adjacent hook carriages 118 are connected together with a flexible means such as a chain 132 which permits close spacing of adjacent carriages not in use as shown in FIG. 10 and a predetermined spacing when it is desired to move the carriages apart to conform to the spacing of the drapery pleats.
  • the pleater blades 21 and 22 of the pleater bars 18 and 19 are preferably of the configuration shown in FIGS. 13 and 14.
  • the blade 22 on the back pleater bar 19 may have a rounded enlargement or top 133 on its outer end which is designed to prevent the drapery from catching on the ends or corners of the projecting blades as the drapery folds are placed in between the blades 22.
  • frictional pads 112 are provided on facing sides of the blades 21 and 22 to facilitate clamping of the drapery fold.
  • the thickness of the two pads 112 on facing surfaces of interdigitated blades 121 and 122 as shown in FIG. 13 is approximately equal to the crosssectional thickness of the blade tip 133.
  • the drapery Before the drapery is attached to the hanger bar 86, it is first folded longitudinally a sufiicient distance downward from the top end to permit individual folds to be fastened to sharp books 110 that are slidably mounted on the hanger bar 86, as shown in FIGS. 10-12.
  • the hanger bar should then be adjusted vertically to a convenient height for fastening the drapery.
  • the weight of the bar itself, plus that of the drapery, is sutficient to lower the bar whenever the pawl 43 is disengaged from the ratchet wheel.
  • the ratchet wheel holds the hanger bar in whatever position it may have been placed by the turning of the crank 25.
  • each individual fold should then be fastened to one of the drapery hooks 110 on the bar while the pivoted pleater bar 18 is in an inoperative or rest position (broken line position of FIG. 3) above the hanger bar.
  • the drapes will then hang down in front of the forwardly projecting pleater blades 22. While they are thus hanging, the folds should be individually placed between adjoining blades.
  • the pleater bar 18 should next be swung down so that its pleating blades 21 will each be disposed on one side of a fold while the other sides of these particular folds are resting against the blades 22.
  • the interleaved or interdigitated pleater bar assembly may then be lowered slowly to permit them to comb out, straighten and pleat the drapery all the way to its lower end.
  • the pleater bar assembly may be freely moved up and down the channels 11 and 12 to effect pleating of the drapery.
  • the ease of movement of the relatively heavy pleater bar assembly is facilitated by the counterweight suspension of the pleater bar assembly with cables 28 in the guide tube 72.
  • the pleated drapery may then be secured by means of bands 164 placed at various intervals along the length of the drapery.
  • the outer end of the bell crank is pivoted to link 29, and the opposite end of link 29 is pivotally fastened to bracket 32 whose hub 33 is pinned, as by a cotter pin 89, to the rod 37.
  • This rod is slidably mounted in the end members 90 and 91 of the U-shaped bracket 34 which is secured, as by welding, to the rear surface of the square tube 50 which carries the pleating bar 19.
  • a compression spring 36 surrounds the portion of rod 39 that extends beyond the upright end 91 of the U-bracket.
  • a washer 42 is mounted on rod 39 adjacent to the spring 36. Both ends of rod 37 are threaded.
  • Nut 38 is threadedly secured to the end of rod 37 that extends beyond bracket 90, and nut 40 is threaded to the opposite end of the rod and tightened against the washer 42.
  • a second compression spring 35 is mounted on rod 37 between bracket 32 and the upturned end 90 of the U-shaped bracket 34. It will be observed that the effective length of these springs and their tension are determined by the positions of the nuts 38 and 40 on the threaded ends of the rod. Springs 35 and 36 control the clamping or locking tension on the drapery. Due to this spring arrangement the clamping tension will be constant irrespective of the thickness of the drapery material. The tension on the springs can be adjusted by tightening nut 40.
  • the entire pleater bar assembly may be locked at any desired elevation by means of lever 23, FIGS. 5, 7, and 8, which actuates two brakes that arrest the vertical movement of the narrow U-shaped channels 69 and 69a, FIGS. 5 and 6, that respectively straddle the rear side members 92 and 92a, FIG. 5, of the upright side channels 11 and 12.
  • the brake on the right side comprises a brake shoe 93a, FIG. 8, to which is attached a frictional lining 79a that grips the outer surface of the side member 92a of channel 12, whenever pressure is applied to the shoe. Pressure is applied to the brake shoe through the compression springs 94 and 95 upon movement of the cam follower plate 70a toward the brake shoe whenever the cam 53a is in a horizontal position, as shown in FIGS. 6 and 8.
  • the cam follower 70a is provided near its opposite ends with apertures that slidably receive the guide pins 77 and 78.
  • the cams 53 and 53a are the opposite semi-cylindrical ends of the brake shaft 52 that is housed within the tube 51, FIGS. 1 and 6, which is welded or otherwise appropriately secured to the opposite end plates 59 and 59a.
  • the brake shaft 52 may be turned through the full angle within which the semi-cylindrical cams move from the position in which they apply no pressure whatever to the cam-actuated clamping plates to the position shown in FIGS. 6 and 8 in which maximum pressure is applied.
  • Lever 23 applies this pressure by means of the compound lever system shown in the broken away portions of FIG. 7. It will be seen here that lever 23 is pivoted on a short shaft 96 extending through the lever 23 and through its hubs 54 which are best seen in FIG. 5.
  • the link 57 which is pivoted to lever 23 intermediate its ends applies an amplified force to the outer end of the arm or pin 58 to which it is pivoted, this arm being integrally attached to the cam shaft 52.
  • Bracket 103 is secured to end wall 104 of channel 60a, FIG. 6, and bracket 103a is secured to end wall 104a of this channel.
  • Spring 102 which surrounds pin 78, expands between bracket 103 and the cam follower plate 70a, and spring 102a, which surrounds pin 77, expands between bracket 103a and the cam follower plate. This expansion moves the plate toward the right (when these parts are oriented as shown in FIG. 8) and the consequent release of pressure from springs 94 and removes the tension from pressure plate 93a and the friction material attached thereto, and the vertically movable pleater bar assembly 160 is then free to move up and down the side channels 11 and 12.
  • the drapery whose folds have been locked between the pleating blades of the two pleater bars 18 and 19 may be stretched, as hereinbefore set forth, by raising the hanger bar 86 by means of the winch 24.
  • the hanger bar is held at its adjusted elevation by the pawl 43 which immoblizes the ratchet wheel 27 attached to the winch.
  • the hammock-like basket 97 serves this purpose.
  • One edge of the fabric forming the basket is held between the cleats 100 and 101 whose ends are mounted on the diagonals 15 and 15a, FIGS. 1 and 2.
  • the opposite edge of the fabric is wound around the rod 99 and attached thereto.
  • the rod 99 is supported by a pair of brackets 98, one of which is shown attached to the rear diagonal 16, FIG. 2. It will of course be understood that a companion bracket 98 is provided on the other side of the pedestal structure.
  • the hammock-like basket 97 hangs down between the diagonals, as clearly shown in FIGS. 1 and 2.
  • FIGS. 15-17 show a modification of the present apparatus to permit the operator to release the hanger bar by merely depressing the foot pedals 136 which are connected to linkage 138 and chain 140 to a winch locking mechanism 141.
