proved methods and means for the manufacture of neckties.

Certain high speed necktie sewing machines such as that shown in U. S. Patent No. 2,098,009 issued November 2, 1937, to M. M. Newman et al., have possessed the disadvantages in that the tie element had to be manually folded, and that the proper gaging of the lining and tie elements was difficult. If the gaging was done manually, it was unreliable; if mechanically, a complicated gage and gearing was required which was expensive and not wholly reliable. In particular, the tie and lining elements would longitudinally stretch to different degrees, so that the result might be off by three or four inches or more in the length of the finished tie.

Accordingly, it is an object of the invention to provide such a sewing machine with a tie and lining presented thereto continuously preliminarily interconnected in a very simple and inexpensive manner, with the tie already folded and in gaged relation to the lining, and without causing the preliminary interconnection to interfere with the crimping of the tie and lining, and the final sewing together of the same.

Another object of the invention is the pro- I vision of such preliminary interconnection in such improved relation to the high speedsewing machine as to permit the tie and lining elements to be stretched as a unit while being fed to the machine.

Another object of the invention is to provide 11 a machine having improved means for gaging and guiding the preliminarily interconnected tie and lining to the sewing apparatus.

Another object of the invention is to provide an improved machine and apparatus for advantageously utilizing a machine such as is shown in U. S. Patent No. 2,186,552 issued January 9, 1940, to M. S. Malek, for gaging, folding and stapling the tiefor a preliminary securement.

Other advantages of the invention reside in that great flexibility of plant operation is obtained. For instance, if the sewing machine happens to break down, the operations with the Malek machine may continue and a reserve built up, or the product of the Malek machine may be ferent ways among the various operators to keep the maximum number of them busy or to utilize the skill of each in the most satisfactory way. These advantages are especially applicable to small plants, whose supply of work may be iriregular, and which may have a rather small number of high speed sewing machines.

Other objects and advantages of the invention will become apparent as the specification proceeds.

With the aforesaid objects in View, the invention consists in the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated in the annexed drawing, wherein like parts are designated by the same reference characters throughout the several views.

In the drawing:

The advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined in one and the same structure, but, useful devices may be produced embodying less than the whole.

It will be obvious to those skilled in the art to which the invention appertains, that the same may be incorporated in several different constructions. The accompanying drawing, therefore, is submitted merely as showing the preferred exemplification of the invention.

, Referring in detail to th drawing, ll! denotes an apparatus embodying the invention, for the practice of the novel, improved method of making ties. This apparatus may include a high speed sewing machine ll, for example, of the type disclosed in the Newman patent referred to. For present purposes, it is suificient to state that this sewing machine comprises endless belts or chains |2 trained over pulleys I3, and carrying cn'mping portions M which are centrally slotted as at IE to receive a needle such as I6. As the members l2 travel, the tie and lining elements are received between adjacent runs of the members and are crimped and continuously fed to the needle which is thus passed through the crimped portions to sew together the tie and lining. After being thus sewn together, the tie is turned inside out.

Th tie unit which is fed to the sewing machine H is indicated at IT, and comprises a longitudinally folded tie ['8 and a lining IS. A preliminary fastening means may consist of a longitudinal clamping means, preferably a row of staples 20, which interconnect the meeting edge portions 2| of the tie IS with the central region of the lining. The tie has been accurately folded and gaged and removably stapled to the lining as by the machine of said Malek patent.

The unit I! is placed upon a table 22 having gage means to properly feed the unit to the sewing machine As the feeding progresses, an operator may remove the staples 20 so that they will not interfere with the needle Hi. If desired, the staples may be retained until after the sewing operation has been completed, and then removed, but this may entail a waste of material at the seam, while if the staples are moved toward the fold lin of the tie, they may catch the yarn in silks and the like.

Co-operating with the tie unit I 1, a gage 23 may act along the relatively straight raw edge at 2| of the folded tie, While a pointer 24 may lie above the row of staples 20. One or preferably both such gages are used, and they may be adjustably affixed to the table 22 as by a set screw 25. Desirably the gaging means lies relatively close to the sewing machine as shown, so that the tie unit may feed between the crimping belts in alined relation therewith.

In Figs. and 6 is shown a modified gaging means which may comprise a table 26 having alongitudinal recess 2'! for the lining. A gage 28 for the edge 2| of the folded tie may be of U-shaped elongated form to receive the meeting edges 2| of the tie. The lower jaw 29 of the U-shaped guide may be quite thin or beveled to readily enter between the tie and lining up to the staples 29, so that a positive guide is obtained by causing the staples to press laterally against the straight edge or jaw 29. The gage 29 may be adjustably connected to the table 26 as by a set screw 39. Th tie unit I! as thus gaged may be slid along the table 26 to be progressively fed to the sewing machine II with one hand, While with her other hand the operator removes the staples 29 as they come near to the sewing ma chine, all as hereinbefore described.

In course of feeding the tie, the operator may pull on the tie unit I l at the end remote from the sewing machine to stretch the unit and assure an accurate feed to the sewing machine. Such stretching is easily effected when once the tie unit has been caught between the crimping jaws. If desired, a tensioning means may include a weight 3| which may be connected to a cord 32 trained over a pulley 33 and having a clip 34 for releasable securement to the end of the unit H to leave the operator free to rapidly remove the staples 20.

In Figs, 7 and 8 are indicated a modified apparatus and method for the practise of the invention, so that the staples 20 need not be removed until after the tie has been sewn. Thus each crimping jaw member 40, which may diagrammatically represent portions of the belt members, has transverse crimping portions or teeth 4| interrupted by grooves for a longitudinal guideway 42 for the needle 43, and smaller transverse groove forming a longitudinal guideway 44 for the travel of the staples 20, as the crimped tie and lining unit I! moves along by operation of the belt members of the machine Ill. Thus the danger of the needle striking the staples is avoided, and the tie unit I! may be transversely crimped to a substantial degree for the sewing operation. While the staples to some degree tend to restrict the crimping, yet the stretchability of the bias fabrics will permit ample yield; in fact, the resultant increased tension will cause the staples to snugly hug the guideway 44 to lie therein.

In the practise of the invention according to Figs. 7 and 8, the staples 20 may be placed further from the edges 2| or closer to said edges to leave some space between the row of staples and the line of sewing. By retaining the staples during the sewing, there is no opportunity for relative shifting between the tie and lining during the sewing operation. The feeding of the tie unit may be effected with gages and means hereinbefore described.

It will now be apparent that the several advantage of the machine and method and flex-- ibility of plant operation can be realized in a high degre by this invention.

I claim:

1. A machine for sewing stapled tie units having confronting jaw members having transverse crimping teeth and a longitudinal groove through the teeth forming a guideway for a needle, and a second longitudinal guideway through the teeth lateral to but closely related to the first mentioned guideway to receive the staples of a stapled tie unit, the second guideway being substantially narrower and less in depth than the first guideway for receiving the said staples and for thus forming a positioning gage for the tie unit.

2. The method of making neckties including folding a tie and gaging a lining therewith, preliminarily interconnecting the tie and lining along a proposed line of sewng by stapling together said tie and lining at spaced points along a line spaced from the proposed line of sewing, longitudinally crimping the tie and lining to form a row of crimps along the proposed line of sewing and sewing them together through said crimped portions while the staples are in position by utilizing a needle of suificient length to pass through a multiplicity of the crimps simultaneously.

3. The method of making neckties including folding a tie and gaging a lining therewith, preliminarily interconnecting the tie and lining along a proposed line of sewing by stapling together said tie and lining at spaced points along a line spaced from the proposed line of sewing, then gaging the tie and lining unit by means of said staples while longitudinally crimping the tie and lining to form a row of crimps along the proposed line of sewing and sewing them together through said crimped portions while the staples are in position by utilizing a needle of suflicient length to pass through a multiplicity of the crimps simultaneously.
