DUPLEX CURTAIN Filed July 19, 1934 i fiery'amin Holyqfe Patented Apr. 14, 1936 UNITED STATES DUPLEX CURTAIN Benjamin 'Holgate, Lowell, Mass, assignor to Boott Mills, Lowell, Mass, a corporation of Massachusetts Application July 19, 1934, Serial No. 736,080

3 Claims.

My present invention relates generally to ornamental fabric curtains for window and like openings, and more particularly to curtains of that type which, in order to permit of the entry of maximum light and air, and at the same time present a pleasing appearance, have been made in two hanging sections, each section presenting a net-like lengthwise panel adjacent to the other section and having the remaining portion of a different relatively close Woven material.

Up to the present time such curtain sections have been made up by stitching the lengthwise close woven and net panels together and it has been necessary not only to stitch gathered rufiles around the edges of the sections but also along the said stitched adjoining edges of the panels in order to conceal the juncture thereof.

According to my invention, I form each of the curtain sections in a single piece having a loosely woven net-like portion or panel adjacent to one side edge, and relatively close woven portions or panels at opposite sides of the loosely woven panel, one side panel being a relatively narrow edge band, so that the above stitching of panels and concealment of the stitched edges is eliminated, with a consequent considerable reduction of the cost of manufacture, while retaining and, if anything, enhancing the pleasing appearance of the curtain as a whole.

The foregoing may be better understood and more thoroughly appreciated from the following detailed description of my invention, reference being had to the accompanying drawing, which forms a part of this specification, and in which,

Figure 1 is a front elevation illustrating my improved curtain in use, and

Figure 2 is a detail plan or face view of a portion of one of the sections.

Referring particularly to Figure 1, I have shown the two sections I0 and II of the curtain, each in one piece. The sections are of like form and constructed from a single oblong web of fabric. Each section includes a group of weft threads A and groups of warp threads B, C, and D. The group A is common to the .said other groups. The threads of group A are arranged throughout in equi-distant spaced relation and include intermediate stretches A, outer end stretches A and inner end stretches A. The stretches A are of greater length than the other of said stretches. The stretches A" are of greater length than the stretches A. The warp threads of the group B are arranged throughout in substantially abutting relation. The warp threads of the group D are arranged throughout in substantially abutting relation. The warp threads of the group C are arranged throughout in equi-distant spaced relation. The distance between the warp threads of the group C is substantially the same as the distance between the weft threads. The number of warp threads B is greater than the number of warp threads D. The number of warp threads C is greater than the number of warp threads B. The warp threads .0 coact with the intermediate stretches A of the threads A to form section I0 or II length-- Wise and from end to end of the section with a loosely woven intermediate panel I2 of uniform width throughout and of lattice-like form to permit of entry of maximum light and air. The threads of group B coact with the outer end stretches A of the threads of group A to form the section II] or II lengthwise and from end to end of the section with a closely woven outer side panel I4 of uniform width throughout and of less width than panel I2. The panel I4 acts to conceal one side of the window frame. The threads of the group D coact with the inner end stretches A' of the threads of group A to form the section I0 or II lengthwise and from end to end of the section with a closely woven inner side panel I2 of uniform width throughout and of materially less width than panel I4. The panel I3 acts as a reinforcing means for the innerside of the section Ill or II.

Owing to the above arrangement of the panels, the curtain in place at a window as in Figure 1 substantially conceals the window frame, by virtue of closely woven innerside panels I4, and also the center sash bars, if there are such, by virtue of the inner closely woven outer side I3, leaving the loosely woven intermediate panels opposite to and extending across the major portions of the glass panes of the window sashes, or the window opening if one or both sashes are open. The intermediate panels I2 are eccentrically disposed with respect to the side edges of the sections of the curtain.

In Figure 1 I have shown the loosely woven intermediate panels I2 of the two curtains in a conventional cross weave, while in Figure 2 I have shown a somewhat more ornamental weave for the intermediate panels I2**, and with reference to Figure 2, there is shown an outer side group of warp threads 14 of the ordinary form, an inner side group of warp threads I4 of the ordinary form and an intermediate group of warp threads I5 of the chain type. The group of weft threads common to the groups I4, I 4 and I5 is designated I6. The threads I6 include outer end stretches I6, intermediate stretches I6 of greater length than the stretches I6 and inner end stretches 16 of less length than the stretches I6. The threads I4 and I4 are arranged relative to the stretches I6 and I6" in the same manner as the threads B and D are arranged with respect to the stretches A and A. The threads I5 are arranged relative to each other in the same manner as the threads 0.. The threads I5 are employed to separate and bind off sets of the intermediate stretches I6" of the threads H5. The outer threads of the group I5 are spaced from the inner threads of the groups [4, I4". The intermediate stretches l6 of each set are arranged in close proximity to each other from one outer thread to the other outer thread of the group I 5. The threads 15 coact with the stretches It" to provide the lattice-like intermediate panel I2 The threads 14' coact with the stretches IE to provide the outer side panel l4, and the threads 14" coact with the stretches W to form the inner side panel 13. However, this arrangement may obviously be varied in other ways so long as the loosely woven panel is of net-like nature in the sense that it readily distinguishes in appearance from the panels l3 and I4 and otherwise answers the foregoing requirements and purposes.

What I claim is:

As an improved article of manufacture, an ornamental window curtain in two similar hanging sections, each section comprising an oblong body including an outer side panel, an intermediate panel and an inner side panel, each of said panels forming an integral lateral continuation from another and disposed lengthwise of and coextensive With said body, said body being formed of an outer, an intermediate and an inner group of warp threads and a group of spaced weft threads common to the said other groups and with the weft threads being formed of outer end stretches, intermediate stretches and inner end stretches, the weft threads being permanently spaced from each other, the warp threads of the outer group being arranged substantially in abutting relation throughout and coacting with said outer end stretches of the weft threads to provide the said outer side panel, the latter having a closely woven characteristic, the warp threads of the inner group being arranged substantially in abutting relation throughout and coacting with the said inner end stretches of the weft threads to provide the said inner side panel, the latter having a closely woven characteristic, the said warp threads of the intermediate group being permanently spaced from each other a substantial distance and coacting with the intermediate stretches of the Weft threads to provide the said intermediate panel, the latter having a loosely woven characteristic to provide it throughout in the form of a lattice, said inner side panel being of a width materially less than that of said outer side panel and constituting a reinforcing means for the inner side of the section, said intermediate panel being of a materially greater width than said outer side panel and of a form to provide for a maximum entry of air and light, and said outer side panel constituting a concealing means for the side of the window frame.
