8 Claims.

This invention relates to drapery and other spaced ribs formed thereon transversely disposed to the longitudinal dimension of the strip in which the ribs are collected into groups in order to form uniformly spaced groups of pleats in the drapery,

Another object of the invention is to providey means for reinforcing the ribs formed in a drapery pleater.

A further object of the invention is to provide a drapery pleater having ribs formed thereon,

the ribs havin-g longitudinally spaced apertures:

therein in which drapery hooks are inserted so that when placed in diierent of the apertures,

' the drapery may be adjusted toward and away from the floor.

A still further object of the invention is to provide a pleater strip for drapery made from comparatively light weight material having transversely disposed ribs thereon for forming pleats in which the ribs not used for pleats, stiften the strip between groups of pleats.

This invention consists of la strip of stiff but foldable material having ribs formed thereon by folding o1' crimping the material at uniformly spaced distances along the length of the strip,

each rib being made secure by sewing it at thev base thereof or gluing the abutting faces of the ribs together. A plurality of uniformly spaced -apertures are cut into each rib. A succession of these ribs are collected together to form a group of pleats in the drapery after the strip of ribbed material has been sewed latwise along or near the upper edge of the reverse side of the drapery so that the ribs project outwardly therefrom. Groups of pleats are uniformly spaced by Iarranging a uniform number of ribs between each group of pleats.

The invention also consists in arranging single o r double draw strings through selected successive groups of ribs so that when the strings are drawn, the pleats will be formed on the drape.

' The invention also consists in providing tubular means between groups of pleats or between the ribs intermediate the groups of pleats so rthat the pleated groups will rem-ain uniformly spaced as Well as assist in preventing folding or buckling ,2 of the drapery between the groups of pleats. The ribs also stiften the material in the vertical direction so that the upper portion of the drapery to form groups of pleats,

The invention is embodied in Vthe structure illustrated in Fig. 1 of the drawings in which the numeral l designates a drapery hung from a rod 2 securable to a window frame in the usualmanner. 'The pleats for the drapery are formed by the use of a pleater strip 3 which is preferably a pyroxylin or a buckram material, sewed on the reverse side and usually along the upper edge of the drapery material.'

The strip 3 has a plurality of uniformly spaced outwardly projecting ribs 4 lformed therein which are made by folding or crimping the strip of material and gluing the abutting faces of the crimped material together or sewing them at the base of the ribs to retain it in position as well as to maintain uniform spacing thereof. Each rib has a plurality of uniformly spaced apertures 5 cut therein and through which an improved drapery hook 6 is inserted. The details of the hook 6 are nhereinafter described in greater detail. Tabs 'I are formed at the end of each rib by cutting a V notch 8 therein, which tabs are sewed flat against the strip 3 when it is sewed atwise to the drapery l The cuts forming the tabs permit ribs d to project outwardly frr'n strip 3. The pleats in the drapery are formed by collecting four ribs into a group and inserting hoo-k E through one of the aligned apertures therein and, when so collected, the pleats 9 are formed on one side of the drape. Another series of ribs A maybe collected to form a second series of pleats 9 and by rspacing 'a predetermined number 'di 'ribs il between the ribs collected and held by a 'drapery hok, the spacing of the pleats will be uniform along the upper edge of the drapery.

The number of ribs collected in 'the above "and iii the succeeding disclosure is always Aone greater than the number of pleats formed. The ribs not llected, 'stiffe'n the material between groups of pleats, thereby 'obviating the use of a heavy stiff material therefor andpermitting the use of lighter weight pyroXylin o'r buclram.

The iii'o'die'cl lfrrn of pleater show-n in Figs. 8 and 9 is processed in a manner similar to that 'shown in Fig. 2 with the exception that the cuts forming the tabs l are omitted. The pleater I has L'ribs vrII uni-formly'spaced thereon, 'each being provided with uniformly spaced apertures lI I for receipt of the drapery hook. The pleater III) is then sewed along the upper edge of the drapery in the customary manner and groups of ribs Il are collected to formpleats similar to those villustrated in Figs. and 6 and are held in position by insertion of the drapery hook through a selected aperture in each 'of the collected ribs. A

tube I 2 is -sewed to the pleater l0 between groups f,

of pleats, thus assisting in maintaining a uniform 'spacing of the pleats A draw string I3 is secured to one of vthe vertical edges of the drapery and is inserted through tube lf2 and through one of the apertures in each Aof the ribs A to be collected, or through a special one for the purpose of forming pleats, and when pleater IIJ is moved rela-tive to the draw string, the ribs through which the 'draw string 'i3 passes, will be collected in groups of four,` thereby forming groups of three pleats, or any other number; such as lillustrated in Figs. 5 and 6. Drapery lhcoks are then inserted through selected apertures in the ribs to furtherfassist in holding the groups of pleats in assembled condition. The tube I2 prevents buckling or folding of the drapery material between the groups of pleats.

F-igs. 'l0 and ll illustrate another-modified form of the invention in which `a pleater strip I6 is vprovided having a `plurality of uniformly spaced I 5 formedtherein in a manner similar to that described in connection with Fig. 2. Each of these ribs has a :plurality of apertures cut therein for receipt of a drapery hook. One end of each draw string I5 and I'l is secured to opposite vertical edges of the drapery and each `passes through a suitable aperture provided in each of the ribs. When the strings are drawn so as to move the pleateriil with respect thereto, `the strings will collect some o-f the ribs `into Cil 'uniform spacing between the rings and groups of pleats, thus preventing folding or buckling of the drapery material between the groups of pleats, The ribs l5 may have their mechanical strength increased by weaving into the stri-p I/i reinforcement threads I5', each rib being reinforced in a similar manner. The rib is formed in the reinforced portion of the strip and may be held crimped by sewing it along the base of the rib, or the abutting faces may be glued, as described above. The ribs of each of the foregoing and the remaining disclosures to be described may be similarly reinforced if so desired.

Figs. l2, 13 and 14 illustrate another form of the invention in which the pleater strip I9 has a plurality of uniformly spaced ribs 2li formed thereon in a manner similar to that described in connection with Fig. 2. Drapery rod apertures 2| are cut in the pleater strip I9 adjacent to each of the ribs t@ and a group of three or more of the ribs are collected together so that pleats 2li vmay be formed in the drapery to which the pleater strip i9 is sewed. A rod 23 -is then inserted through the apertures formed in the strip so that the collected group of ribs will be maintained in collected condition. The rod 23 is not passed through ribs 2i) arranged between the groups of ribs so that the spacing between them may be maintained uniform. The ribs 2l) do not have apertures cut therein for receipt of drapery hooks for the reason that the drape is suspended from rod 23.

Under certain conditions the pyroxylin or buckram material having a simple crimp therein, may not have the required mechanical strength to support the drape and in order to overcome this mechanical weakness the pleater strip 24 having a rib 25 formed therein, has a reinforcing strip 26 placed between the crimped material; This reinforcing strip may be sewed in -place orglued thereon, as desired. An additionalo'reinforcing strip, which is a continuation of strip 26, may be positioned adjacent to one of the Afolds or the ribs 25 and secured thereto by stitching or gluing. This mode of reinforcement may be applied to each rib of the Aforegoi'r'ig disclosures and used in each of said disclosures in lieu of that discussed in connection with Figs. l0 and ll1.

l N Another modified form of the invention is illustrated in Figs. 17, 1S and 19 which comprises fapleater strip 21 in which ribs 28 are woven.

This is accomplished by uniformly looping some f the warp threads between the sides of the strip to form ribs 25. Other of the warp threads are not so looped and, in combination with the transversely "arranged Woof threads, will hold the ribs in Iposition and maintain the uniform spacing thereof. The ribs 23 are not provided with apertuies, such as shown in Fig. 2, but to enable a drapery hook to be uniformly positioned in each of the 'collection of ribs whereby pleats are formed after the pleater strip is sewed to the drapery, a variety of colored warp threads 29 are provided in order to serve as a guide for insertin of the drapery hook at the same level. The same result may be achieved by omitting selected warp threads and introducing a given number of larger threads than the warp threads forming the main body of the pleater strip 21. Each of these expedients will enable the person hanging the drapery to place the hook in the same relative vertical position on the pleater strip.

An improved drapery hook 6 is illustrated in Fig. '7 and comprises a pointed member 30, looped as at 3|, and having a member 32 extending parallel to the pointed member 30. It also has a loop 33 formed therein and a continuation thereof in member 34 constitutes, with member 32, the hook which is placed over a suitable support or drapery rod. The plane in which

members

30 and 32 lie, is preferably disposed at right angles to the plane in which .the members 32 and 34 lie. This right angle plane arrangement of the hooks enables the

members

30 and 32 to act as a clamp for the ribs on the pleater strips held by loop 3l, thus clamping the group of ribs so that the pleats may be more perfectly formed in the drapery. The members 32 and 34 are thereby better enabled to support the dr-ape in the desired position. The drapery hook 6 is formed from a single piece of Wire and constitutes an effective and eicient accessory for the various pleater strips illustrated and described.
