13 Claims. Cl. 112-174) Neckties of the four-in-hand type customarily are composed of an outer tubular covering f abric and an inner reinforcing lining fabric. This invention relates to a method of and app for simultaneously stitching together the edges of the covering fabric to form the tubular outside, and the interior lining fabric.

The object of the invention contemplates a very simple method whereby with a small and inexpensive apparatus the stitching of a cover and lining can be easily, quickly and satisfactorily accomplished.

In attaining this object the covering material is folded upon itself with the inside out and placed full length flatwise on a bed, and'the lining material is laid over the free edges of the covering material. The cover and lining are then engaged at intervals and looped transversely, preferably by intermeshing .the teeth of an upper comb with the teeth of a lower comb, and a threaded needle is thrust through all of the several loops at one pass. Following the'withdrawal of the needle the thread is cut, leaving a thread through the loops, the cooperating looping means are disengaged, the fabric is stretched out to open the loops and finally the tie is turned inside out, so that the cover will be on the outside with its free edges stitched together and the lining stitched approximately down the middle of its length inside of the cover. l

The accompanying drawings illustrate an apparatus by means of which the method may be practiced, showing the various. actions of the mechanisms and the product produced thereby.

Fig. 1 shows a top plan View of the apparatus with the teeth of the upper comb raised and the teeth 'of the lower comb separated and in position to receive the covering and lining to be stitched.

Fig. 2 shows a front elevation of the same.

Fig. 3 shows a view of the stitched lining and covering material.

Fig. 4 shows on larger scale a top view of a portion of the needle end of the lower comb with the teeth separated and a piece of lining and piece of covering material laid thereon.

Fig. 5 on still larger scale is a vertical section taken on the dotted line 55 on Fig. 6, which shows a side view of a tooth of the lower comb in position to receive the fabrics, and also in full lines one of the clamps and the upper comb that cooperate with the lower comb for looping the tie fabrics, raised.

Fig. '7 is a section on the planedenoted by dotted line l-l on Fig. 8 showing the relative positions of the comb teeth and clamp jaws when they have acted to loop the tie fabrics, with the needle about to enter and eflect the stitching.

Fig. 8 is a. side view of what is shown in Fig. 7.

The apparatus illustrated for practicing the method has a bed I of sufficient length and width to receive a tie laid flatwise thereon. n the bed is a collapsible comb which is comprised of a plurality of separable transversely movable blocks 2 provided with teeth I. The upper edges of the teeth are approximately flush with the upper surface of the bed, and, with the blocks, are movable transversely with relation to each other. The blocks have T-shaped tongues 4 on their under side that are slida'ble in a correspondingly shaped groove in the bed, and they are connected together by lost motion links 6 so that they may be drawn apart to separate the teeth from each other and may be pushed together so that there are but small spaces between the teeth. The blocks may be drawn apart or may be pushed together by a lever and link mechanism I that may be actuated by hand or any suitable mechanism.

Pivoted to each block near its rear end, and movable transversely therewith, is a forwardly extending arm 8. The front end of the arm has a clamp jaw 9 with a roughened under surface that is adapted to be swung into engagement with or turned away from the tooth 3 of the block to which the arm is pivoted. A small spring l0 normally tends to press eac law against its tooth with a light tension. Ea h arm has a rearward extension H with a forked end that is adapted to be engaged by a rod I! the ends of which are supported by vertically movable slides B that may be drawn down at the proper time by hand or by a treadle, as desired.

Mounted on the bed so that it may be swung to and from the collapsible comb is a comb which is comprised of a bar H with thin teeth I5 projecting therefrom. The teeth ii of this comb are located transversely so that they will alternate with, or mesh with, the teeth 3 of the collapsible comb when the latter comb is collapsed. The ends of the bar M are fastened to-arms l6 that are attached to a shaft H which is pivotally carried by brackets l8 secured to the back of the bed. This upper comb may be swung up and down manually by a handle I9 attached to the shaft H or by any convenient mechanism. When the teeth 3 of the collapsible comb are drawn together and the upper comb is swung down, its teeth II .will pass into the spaces between the teeth l. Across the upper edges of the comb teeth 3 are notches ll, and across the lower edges'of the comb teeth ll are'notches Ii. when the comb teeth are meshed all of these notches are aligned and form a guide forthe stitching needle. r

Movable transversely of the bed, near the side to which the collapsible teeth I are pushed to bring them together, \is a slide 22 to which is attached a long needle 21 with. an eye 24 near its point end. When the slide is drawn out to one side, which may be accomplished manually by a'handle II or by any convenient mechanism, the point of the needle is free from'the comb teeth. With the teeth of the comb meshed together the slide may be pushed low that the needle will pass through and be guided by the aligned notches ll and 2| in the comb teeth.

a spindle II'may be set on the bed near the needle slide-for a spool of thread, and if desired a cutting blade 21 may be attached to the' bed at this end. Acres the upper surface of the 'flngersiisalineil andalsoallnell- These lines may be formed by notching the upper surfaces of the fingers and filling the notches with material having a color that contrasts with the color of the fingers.

In using this apparatus and practicing the method, the fabric II that is to be the outside of the tie is folded lengthwise upon itself with the inside out, and placed full length fiatwlse on the bed overthe collapsible'conib with its free edges flush with the line 28. The lining fabric II is then laid over the free edges of the covering fabric with its rear edge fiush with the line 29. The arms with the clamp laws 9 are turned down so as to lightly bind the covering material and lining between the jaws and the teeth of the collapsible comb. This comb is then collapsed'so that the teeth and jaws will slacken the fabric between the teeth. The comb I4 is then turned down until itsfteeth pass between the teeth of the collapsible comb and uniformly loop the slack fabric between the teeth. With the covering and lining. held in this relation the threaded needle is thrust through the loops. As the notches inthe upper comb teeth complement the notches in the lower comb teeth and.

form a guidingpassage the needle will not flex but pass straight through the loops. After the threaded needle is thus passed through the loops the thread may be held and the needle drawn back out of the loops.

The thread is cut with ends sufilciently long to be fastened so that the thread will not be withdrawn from the loops when the stitched tie is straightened out. With the needle withdrawn the upper comb is turned up, the teeth of the lower comb and the clamp jaws are separated, and the tie is drawn out so as to flatten the loops. The lining and. the covering thus stitched areturned inside out so that the covering fabric will be on the outside and the lining fabric on the inside of the seam which stitches together the free edges of the covering.

By this method and with'this simple apparatus the covering and lining are stitched with one movement of the needle.
