Fig. 11 is a vertical section taken on line I Ill of Fig. 10.

Referring now to the accompanying figures and first to Figs. 5 and 6, my improved dress goods material comprises a base fabric l of suitable textile material on the outer surface of. which parallel rows 2 of decorative tapes are secured. Each of the rows 2 comprises at least two strips being disposed in sinusoidal form and strip 4 being superimposed upon strip 3 in such manner that the strips cross one another at intervals, as indicated, for example, at 5.

The two strips are secured to each other and to the base fabric 1 by means of a single continuous line of stitching indicated by reference numeral 6. At the regions I intermediate the points where the strips cross one another the concave edges of the two strips preferably just touch each other so that the maximum widths of. the rows 2 are the sum of the width of the tape strips 3 and 4, and at the same time the single line of stitching 6 secures both of the tapes to the base fabric substantially continuously throughout the entire length of the rows 2.

The strips 3 and 4 may be of any appropriate width and of the same, or contrasting, colors to suit the taste of the designer. As shown, the sinusoidal, or wavey, forms of the two strips 3 and 4 are preferably arranged so that the crests of one strip come opposite the valleys of the other strip, or, in technical language, the phases of the two wave forms are apart, but any desired modification of this arrangement may be made.

In the modified form of dress goods illustrated in Figs. 8 and 11, the base fabric is. is provided with tucks 8 and the rows 2a of sinusoidal tapes are sewed into the tucks in such a manner that a portion of each row of. sinusoidal tapes is concealed within the tuck, leaving the other portion exposed and providing a decorative effect along the edges of the tucks. The rows 2a of sinusoidal strips are held in place by means of the same lines of stitching 9 which hold the folds of the base material is which form the tucks.

Referring now to Fig. 1 of the drawings, there is here illustrated a sewing machine having a table l0 mounted at the right hand end of which is the usual overhanging arm H which supports at its left hand end the mechanism for actuating the needle l2 of the stitch-forming mechanism. The shuttle and other parts of the stitch-forming mechanism including the feeding mechanism for feeding the material to the stitch-forming mechanism, none of which are shown in the drawings, are contained within a housing l3 (see Fig. 2) which is supported upon the table Ill, and thereby elevates the stitching or sewing level above the top of table [0. The various shafts, cams, etc., for actuating the stitch-forming mechanism, including the feeding mechanism, are contained in the housing I3 and the overhanging arm H, and are driven by means of a shaft I4 shown at the right of Fig. 1. Power for driving this shaft is applied by means of a small belt 5 to a suitable pulley mounted upon shaft M.

The mechanism for guiding the tapes 3 and 4 and properly presenting them to the needle l2 of the stitch-forming mechanism in order that they may be secured to the base fabric by the line of stitching I (see Fig. 3) comprise a pair of shifting, or reciprocating, guide plates l6 and I! which are secured to the right-hand ends of a pair of parallel slide bars l8 and I9. These bars slide in a pair of parallel grooves in a supporting arm 20. The slide bars l8 and 19 are reciprocated in appropriately timed relation with respect to each other by means of crank pins 21 and 22, respectively, arranged in the faces of a pair of small crank pinions 23 and 24. The crank pins 2! and 22 are connected to the slide bars l8 and i9, respectively, by means of connecting rods 25 and 26.

These crank pinions 23 and 24 are driven from a common driving gear 21, and, as illustrated, are so meshed with this gear as to place the crank pins 2| and 22 180 apart so that as the base material l and the tape strips 3 and 4 are simultaneously fed to the needle [2 and feeding mechanism of the stitch-forming mechanism, the two tapes will bev applied in crossed sinusoidal form, as shown for example in Fig. 4 which shows the guide plates l6 and H in the positions which they occupy when crank pins 2! and 22 have rotated one half a revolution. In other words, in Fig. 4 the shifting of the guide plates l6 and if has caused the tapes 3 and 4 to be shifted respectively to the opposite sides of needle i2 from that which they occupy in Fig. 3. This causes the tapes to be applied to the base fabric in the form of two sine waves directly out of phase with one another.

The two tapes 3 and 4 are fed to the needle l2 through a horizontal tube 28 which is mounted on the edge of the supporting arm 20 nearest the operator, and passing out of the right-hand end of this tube the tapes pass through two guiding slots 29 and 30 which are placed at an angle of 45 to the tube 28, thereby changing the direction of feed of the two tapes into parallel relation with the feed of the base fabric l which, it will be understood, is fed to the stitching mechanism manually by the operator. Guide slots 29 and 30 are positioned in a thin metal plate 3! which is mounted in the upper side of supporting arm 20 and projects beyond the right-hand end thereof and serving as a guard for the base fabric l to prevent it from becoming entangled with the tape shifters It and I! and. the slide bars I8 and i9; Plate 35 is mounted in adjustable position on arm 20 by means of two screws 32 which engage suitable slots in the plate and in this way the position of guide slots 29 and 39 can be accurately adjusted with respect to the needle l2 It will be observed from Fig. 2 that the tapeshifting plates l5 and I! are made of metal which is as thin as possible and still provide the necessary rigidity to properly shift the tapes back and forth, and also that the two tape-guiding slots 33 and 3 are vertical so that the tapes pass downwardly through these slots and are delivered thereby closely adjacent the surface of the base fabric l This permits the guide slots 33 and 34 to be placed closely adjacent to the needle l2 and shortens the movement of the tapes between delivery from these slots and the point of stitching. It also enables the tapes to be delivered through the guide slots into frictional contact with the surface of the base fabric. All of these factors assist in the desired end of placing the tapes accurately in position on the base fabric.

The arm 2t which carries the tape-shifting mechanism is supported on a housing 35 which is fixed to the sewing machine table [0 near its lefthand end, and the height of which is substantially equal to that of the housing I3. Arm 2!] is constructed so as to be interchangeable with the tucking blade controlling arm i5 of the aforementioned patent of Messrs. Carroll and Meyers in order that whena sewing machine is once equipped with housing 35 and its associated mechanism, arm 29 of the present application can be placed upon a housing when it is desired to make the improved fabric described herein, and this arm can be replaced by arm |5 of the patent when it is desired to make graduated tucks upon the sewing machine in accordance with the provisions of the patent.

Accordingly, housing l5 and its associated mechanism are identical with the corresponding housing l4 and its associated mechanism of the aforesaid patent. This mechanism will therefore be described only briefly herein, reference being made to the specification of the patent for the details. Vertical shaft 36 which corresponds to shaft 29 of the patent is driven through a jaw clutch 3'! which is releasable by a horizontally slidable pin 38 by means of a reducing bevelled gearing 39 and a reducing helical gearing 40 by means of a flexible shaft 4|. This flexible shaft is driven by means of a belt 42 and stepped pulleys for speed adjustment from the right-hand end of shaft l4 of the sewing machine.

The upper end of vertical shaft 36 projects through the top of housing 35 and terminates in a threaded portion 43 upon which is a knurled nut 44, or equivalent means for removably positioning the arm upon vertical shaft 36. When it is desired to change over the sewing machine from making graduated tucks, for example, to making the fabric of the. present invention, knurled nut 44 is removed and a straight bushing 45 is inserted in place of the shouldered bushing l6 of the patent. Arm 20 is then placed upon bushing 45 and gear 46 upon the slabbed portion 41 of the upper end of shaft 36 and knurled nut 44 is then replaced upon the top of the shaft to hold the parts in place.

The reducing gearing comprising worm gear 40 and bevelled gears 39 is provided within housing 35 for the purpose of operating shafts 36 at the proper speed to actuate the graduated tucking mechanism of the aforesaid patent. The tape shifters l6 and I? of the present mechanism, however, must be reciprocated at a comparatively high rate with respect to the speed of the stitch-forming mechanism. Consequently the crank pinions have a small number of teeth in comparison to their driving gear 21, and the speed at which the crank pinions are operated is still further increased by means of gear 46 which drive gear 21 through two small pinions 48 and 49. It will be understood that the distance between crests of the sinusoidal tapes can be varied for a given setting of the sewing machine feed mechanism by shifting belt 42 upon its stepped pulleys, thereby changing the number of reciprocations of the tape shifters l6 and I! for a given number of revolutions of the sewing machine shaft I4 or, what amounts to the same thing, for a given number of stitches.

My improved tape guiding mechanism is unusually convenient for the operator to use, inasmuch as the arm 20 can be swung toward the operator, as indicated by the arrow and dotand-dash lines in Fig. 1, to facilitate the threading of the sewing machine or the manipulation of the base fabric and tapes. The arm may be swung about bushing 45 as a pivot to any desired position, that is, it can be swung only a short distance away from operating position, as indicated by the dot-and-dash line just referred to, or it can be swung into a position or more from the operating position if desired, in

order, for example, to use the machine temporarily for plain stitching.

The tape-shifting mechanism isalsoconvenien to set up for operation. The manner of mounting arm 20 upon shaft 36 of support 35 has been described above and requires only a few seconds time. In addition, however, to mounting arm 20 in its operating position, the tape shifters l6 and i! must be adjusted to cause the tapeguiding slots 33 and 34 to reciprocate equal distances on opposite sides of the needle [2 and line of stitching To facilitate this adjustment the .slide bars i8 and I9 which actuate the tape shifters I6 and I! are each made in two sections connected to one another by means of the screw and slot connections 50. By this means the positions of the tape-guiding slots 33.and 34 can be quickly adjusted.

Referring now to Figs. 9 to 11, inclusive, there is here illustrated a modification of the tapeshifting mechanism above described by means of which the modified form of fabric shown in Fig. 8 is produced. By means of this mechanism the base material la is tucked and the crossed sinusoidal tape strips are simultaneously sewed into the tuck and secured therein by the same line of stitching 9 which form-s the tuck.

The modified form of tape-shifting mechanism of Fig. 9 is similar to that previously described except that metal guard plate 3| is removed and in its place there is provided a guidiing blade 5| of thin sheet metal. Tape guiding slots 29a and 30a are provided in this blade in line with the right hand end of tape-feeding tube 28 for changing the direction of feed of the tapes 3 and 4 into the line of feed of the base mate-rial is to the needle IZa.

Referring more particularly to Fig. 10, in operating this mechanism the base material la, is folded around the right-hand edge of blade 5| and carried beneath this blade, the position of the right-hand edge of the blade having been adjusted by means of screws 32a to the proper distance from the needle |2a to give the desired width of tuck. The tape shifters It and I! are also adjusted by means of the screws 50a to cause their tape guiding slots to reciprocate equal distances on opposite sides of the needle. The sewing machine is then started and the base material '8, is fed by hand around the tucking blade 5| to the stitch-forming mechanism by the operator in the usual way. This causes the two plies of the material '8. on the upper and lower sides of tucking blade 5| to be stitched together by the line of stitching 9 and simultaneously therewith the two tape strips 3 and 4 are automatically placed in position between these two plies of fabric by means of the tape-shifters l6 and I1. As shown in Fig. 10, a previous tuck has been made, and this serves as a guide-.for the operator in making the tuck just described.

It will be observed that tucking blade 5| is provided with a finger 52 which guides the fold of the tuck up substantially opposite the needle lZa so that there is no opportunity for the material to shift out of position after leaving the tucking blade. Also the blade is provided with a recess. 53 just to the left of the finger 52, as viewed in Fig. 10 so as to facilitate the adjusting of the tape shifters l6 and I1 independently of the adjustment of tucking blade 5|, and also to facilitate the threading of the tapes 3 and 4 through the tape guide slots in the tape shifters.

It will be understood that changes may be made both in the improved product and the improved apparatus of my invention without departing from the spirit thereof, the scope of the invention being defined in the appended claims.
