15 Claims.

This invention relates to the production of neckties and more particularly to a machine which is adapted to sew the necktie fabric and lining together. The application is a continuation in part of my prior application Serial No. 75,595, filed February 10, 1949. y

In the above entitled prior application, it was pointed out that sewing machines having an elongated needle for stitching together the necktie lining and the edges of the necktie were known but that their use had been associated with some disadvantages. Such disadvantages included the non-adaptability of many prior mafchinestoward accommodation of necktie fabrics which deviated from predetermined dimensions. Such machines would produce a distorted finished product which would be rejected as unusable. A further disadvantage was frequent breakage of the needle in that its guiding path was not properly formed. The instant invention is an improvement over the sewing apparatus disclosed in the above entitled application and further corrects or eliminates the above mentioned disadvantages.

The instant invention further produces an apparatus which does not distort or stretch the fabric in 'corrugating it preparatory to sewing the necktie elements together. This is. accomplished by providing a collapsible stand comprising a plurality of lazy tong mechanisms and whereby the fabric, including the lining, becomes reduced in length through collapsing of the lazy tongs whereupon the elongated needle is actuated throughout the length of the necktie. Mounted on the lazy tongs are a plurality of aligned crimper bars which determine the crimping or corrugation of the necktie elements preparatory to sewing them together. The crimper bars are further provided with impaling needles for preventing undue movement of the necktie elements while they are being properly folded and sewn. The crimper bars are further formed with mating recesses which jointly provide the needle guide path.

The invention further simulates hand operations in the sewing of neckties in that it aifords an adjustment of the crimper bars so that the lining is not stitched to the outer fabric along front and end portions thereof as is desirable in necktie production.

The sewing apparatus of the instant invention greatly simplifies the mechanism heretofore required in effecting what I consider superior results to those of prior constructions. Thus, the instant machine is simple to operate and far more economical to manufacture while nevertheless 2 providing superior action in the sewing of neckties.

The invention will be further understood from the following description and drawings in which:

Fig. 1 is a top plan view of a sewing machine constructed according to the instant invention.

Fig. 12 is a cross-sectional view along the lines !2f2 of Fig. 1. l

The apparatus comprises a frame 20 having a top flange 2| and a center flange 22. Center flange 22 supports the lazy tong mechanism comprising the lazy tong arms 23, upper bars 24, and lower bars 24a. Lazy tong bars 24 and 2412 are respectively disposed on both sides of the lazy tong arms and are interconnected as by rivets 25. Arms 23 are pivotally mounted on end pins 26, quarter point pins 26a, each of which is vertically movable in relation to the bars, while the central point of the lazy tong arms are pivotally mounted on the center rivets 21 which are connected to the bars. Spacers or washers 2B are disposed on the pins or rivets between the lazy tong arms for the usual purposes. It will be recognized from the foregoing that the lazy tongs per se comprise the usual elongated arms which, as illustrated in Figs. 1 and 2, are pivoted at their ends, center, and quarter points and cross other arms at such pivot points to accomplish the scissor-like action characteristic of lazy tong mechanisms. The bars 24 and 24a have end flanges 29 which embrace the pins or rivets 26 nected t'o'bar 24 as by screw 41.

so that the lazy tong arm ends may slide within the bars during extension or collapse.

Supported on the bars 24 are the crimper elements or bars which corrugate or crimp the fabric in cooperation with the collapse of the lazy tongs. Thus, stationary crimpers 38 are con-- nected as by screws 3| to the upper bars 25, the term stationary being employed to indicate absence of relative movement between them and the bars, Each. crimper 3! has a triangular working surface terminating in an apex 32. It

is this triangular face of the crimpers whicheifects the crimping action in cooperation with the opposing swingable crimper element-or bar as will hereinafter be described. 7

As will be understood in the operation of this machine, it is necessary to form a needle guide path when the tie lining and fabric are corrugated or crimped. A portion of such needle guide path is provided by central recesses '35 formed in the apex 32 of crimper bar 30. Means are also provided in the present application to hold the lining and fabric securely in position when theyare set in place, and impaling needles 36' serve this purpose. Needles 36 are formed with integral enlargements 31' for insuring retention of thefabric elements after they have been set in place.

The invention further contemplates adjustability of the'crimper bars to accommodate neckties of various dimensions. For this purpose, the crimper bars are rendered transversely adjustable on the bars 24. Thus, crimper bar 30 is formed with a slot 38 through which operates the screw 3! for tightening the crimper bar 30 to bar 24' in various positions of transverse adjustment. 7 The opposing or swingable crimper bar has a working or surface element which is V-shaped so as to complement the triangular faceof crimper bar 30. The extremeupper ends of the V arms of crimper bar 40 are provided with end recesses 4| which mate with recesses 35 when the lazy tongs are collapsed so as'to form a continuous needle guide path. Crimper bar 40 is further formed with a central hole 42 for receiving impaling pin 36 when the crimper bars are engaged as illustrated in Fig. '7. It will be recognized from Fig. 2 that the crimper bars 30 are alternately provided withimpaling needles 36 and recesses 42, the same arrangement being found in the crimper bars 40 so that the impaling needles are found on both sets of crimper bars.

Means are provided to render crimper bars 49 swingable' in relation to bars 24 so that the crimper bars may become engaged when the bars 40' are swung into position over the bar 33. Thus; acentral hinge comprising a fixed hinge arm 45-and a swin'gable hinge arm 46 are con- A connecting link 48 having a longitudinal slot 49 adjustably connects crimper bar 40 to hinge arm 43 as by the screws 50 which may be tightened in slot 49 to provide transverse adjustment of crimper bar 40. It will beunderstood that when the crimper bars are engaged as illustrated in Fig. '7, it is necessary for both the recesses to align themselves properly and for the holes .2 to be in correct position for receiving the needles 35. The distance between the longitudinal center of the machine and either sets of

recesses

35 or 4! must be the same because hinge pin 52 is at such center of the machine. bar 30 is adjusted transversely as hereinabove described, it is necessary to do the same with crimper bar 40 by means of link 48. In this way,

Therefore, if crimper the needle path recesses may be aligned, the im paling needle receiving holes 42 assuming the correct position at such time. with relation to the impaling needles. In order that the approximate center of the fabric be securely held during the swinging engagement of the crimper bars, a central impaling needle 53 is provided as will be hereinafter made clear.

Referring to Fig. 1, most of the swingabl crimper bars are interconnected by a manipulating member 55 comprising a handle and an elongated rod extending through substantially all of the swingable crimper bars 40. However, two end crimper bars 40 are not connected to manipulating member 55 so that they may be swingably actuated'independently of the remaining swingablecrimper bars as will be hereinafter more fully explained.

The invention is practiced as follows:

A tie lining L is first applied over the stationary crimper bars as illustrated in Fig. 2, the impaling needles 3B penetrating the lining as it is thus applied. In conventional manufacture of neckties, it is desirable to run the thread through the end of lining L without sewing the necktie fabric thereto. Accordingly, the two end crimper bars are then swung over the stationary crimper bars as illustrated in Fig. 3 before the necktie fabric F is applied in position. In this way, the needle will enter the aligned needle guide path Without sewing the fabric F to the lining at the end crimpers.

Thereafter, the necktie fabric F is placed in position over'the lining L and so that the impaling needles 36 securely hold both edges of the necktie lining. It will be observed that central impaling needle 53 holds the center of the fabric down so as to prevent accidental displacement during operation of the crimper bars.

The operator then grasps manipulating member 55 and swings the crimper bars 49 over crimper bars 30, an action which folds the fabric F so that its ed'gesbecome coincident over the lining L as illustrated in Fig. 4. It will be observed-inFig. 3 that the

recesses

35 and 4| are disposed laterally and inwardly relative to the impaling needles 36 so that the aligned needle path is--formed' directly laterally inwardly of the coincident or superimposed edges of fabric F. Accordingly, when the sewing needle is caused to enter and traverse the aligned needle guide path, thesuperimposed longitudinal edges of the fabric F are then sewn to the approximate center of the lining L.

After the crimper bars have been engaged as illustrated-in Fig. 4, the entire lazy tong mechanism is collapsed in order to crimp or corrugate the lining and superimposed fabric. This step is illustrated in Fig. 5-where the small end of the necktie fabric is bent back to illustrate the entry of the'needle into the guide path.

Collapse of the lazy tong mechanism with the consequent crimping of the fabric and necktie lining and the formation of the aligned needle guide path is-illustratedin Fig. 8. It will be observed that the recesses 35 and 41 mutually align to form a substantially continuous needle guide path, the continuity being interrupted by the thickness of the fabric and tie lining between adjacent crimper bars. It will be "understood that the representation of the lining and fabric thickness are-exaggerated i-n Fig. 8 so that in actual practice the space between adjacent portions of the needle guide path is minimal. When-the needle N'bearing the thread T is caused to enter and traverse the needle guide path emerging therefrom as indicated in the broken lines of Fig. 8, the thread T will sew the longitudinal edges of the fabric F to the lining L through the crests thereof, the stitches being slip stitches and being spaced according to the width of the corrugations as will be evident. After this operation, the lazy tongs may again be extended and the sewn necktie fabric and lining removed from the apparatus.

In order to provide lengthwise adjustment of the lazy tong mechanism so as to accommodate neckties of various lengths, a bolt 60 (Fig. 1) may be screwed through a selected one of a series of openings BI so that the end bar of bars 24 will be limited in its extending movement according to requirements. The opposite end bar is, of course, secured to the frame as illustrated in Fig. 2. Some of the bars are further provided with rollers 62 to facilitate the collapsing or extending action of the lazy tong mechanism.

It will be understood from the foregoing that a necktie sewing machine has been provided wherein a series of crimper bars are actuated by simple means so as to prepare a combined necktie lining and fabric for crimping and subsequent sewing for the purposes herein described. The mounting of such bars on the lazy tong mechanism insures proper sewing without distor tion of the fabric. Other advantages will be ap parent to those skilled in the art of manufacturing such neckties.
