29 Claims; (01. 112 174) This invention relates to sewing apparatus and more particularly to a machine which is adapted to sew neckties.

Sewing machines having an elongated needle for stitching together the necktie lining and the edges of the necktie are known but their use has been associated with some disadvantages. For example, the machines are not well adapted to accommodate neckties which deviate from predetermined dimensions. In other words, if the machine is set up to sew neckties of a particular size, those which have been cut larger will produce distorted finished products which may be rejected as unusable. Another disadvantage has been frequent breakage of the needle in that its guiding path was not properly formed.

The sewing apparatus of theinstant invention eliminates the above mentioned disadvantages. In addition, a more positive and reliable operation is secured in that there is less chance-for interacting elements to become improperly engaged.

Another object of the instant invention is to produce such asewing apparatus wherein the tie elements may be initially disposed in proper position which position will be substantially maintained until the sewing operation is completed. Thus, the operator may be substantially assured that the elements of the necktie will be properly sewn in the relationship which he considered desirable.

' Another object of the instant invention is to provide a necktie sewing apparatus wherein the initialpositioning of the fabric insures 1711630? curacy of the fold for sewing its edge together and brings such edges properly together in position to be sewn by the travel therethrough of an elongated needle. I

The apparatus of the instant invention is fur.- ther designed so that it may sew neckties of differing dimensions and shapes. Thus, the lining and fabric supporting elements may be initially shifted into proper position for producing runs of varying necktie sizes.

Other advantages and objects such "as the comparative simplicity of the apparatus will appear from the following detailed description and drawings.

. Fig. 1B is a third embodiment.

Figs. 1 to '7 disclose a simplified form of the apparatus and comprisea pair of platforms or blocks I5 and it which are formed with ears I! wherein are disposed pivots 18 so that the platforms [5 and I6 are pivotally connected. As noted in Figs. 4 and 5, platform [5 may be stationary and supported on legs 20 and 2!.

Maintained on platform I5 is the corrugated strip 22 which preferably, but not necessarily, as:- sumes the approximate form of the necktie lining which is to be sewn to the necktie. In this embodiment, the strip 22 has been illustrated as a single unit, but in actual practice it may be desirable to employ the split or adjustable form thereof illustrated in Fig. 8 et seq. Strip 22 engages the complementary strip of platform 16, in forming a predetermined needle guide path for sewing the necktie and in determining the-nature disposition of the stitches. As illustrated in Fig. 2, the surface of strip 22 is formed from crest 23 and valleys 24. Each crest 23 has formed therein a recess 25 which extends substantially to the dotted line position of Fig. 2. 7 Such recesses may be produced by filing each crest to the desired depth. Strip 22 may be shaped to comprise two somewhat trapezoidal end sections 26 and 21 and a connecting central elongated rectangular sec tion 28. Sections 25 and 21 respectively accommodate the front and back portions of the necktie while section 28 represents the neckband portion. The axis of each end section 26 and=2l is arranged to be inclined to the axis of section 25,

such inclinations of the end sections being toward each other. The strip 22 is formed with needle holes 30 in which the fabric impaling nee' dles travel as will be hereinafter described:

Platform IB is provided with a strip 35 which is complementary to the strip 22 of the platform 3 I 5. Strip 35 is formed with flattened crests 3'6 and narrowed valleys 31 which mate with the respective crests and valleys of strip 22 when the platform I6 is pivoted and overlie platform in the position illustrated in Fig. 5. Strip 3 5 substantially duplicates the shape of strip 22. It

is formed with a series of somewhat elongated,

recesses .38 in the crests thereof, the approximate depth being indicated by the dotted line of Fig. 3. Such recesses 38 may be similarly formed by filing away central portions of the crests 36. Fabric lmpaling needle holes are likewise formed through strip 35 so as to mate with such needle holes of strip 22.

As illustrated in Fig. 6, the necktie lining L is placed in position along strip 22 asis a longitudinal edge portion of the necktie fabric T. The opposing strip 35 receives only the opposite longitudinal edge portion of the necktie fabric T and no portion of the lining L. Means are then provided to press the layers of fabric into the valleys 24. Such means take the form of the pivoted rod structure 46 comprising a series of rods 4| rigidly supported by a shaft 42. Shaft 42 is pivotally maintained in bearing lugs 43 and 44 and is provided with a handhold member 5. Pivotal rotation of hand hold member 45 from the position shown in Fig. 1 brings the rods 4| into the position shown in Fig. 6 so that the rods push the fabric inwardly and into substantially snug fitting engagement with the crests 23 of strip 22. 'Theqrods 4| may be of varying lengths as illustrated so that they occupy the same relative outward position as the line of recesses 25. It may be here noted that both the necktie lining and necktie fabric are generally cut on the bias so that they may stretch inlengthwise direction. Such bias cut is of assistance in permitting any required stretch ofthe fabric in order that it may be properly seated in the recesses 24. However, and as will be evident, the rods 4| may be individually pressed down when in operative position soas to assure proper seating of the fabric onthe strip 22. Platform I6 is also provided with a rod structure .50 which serves the same function as the rod structure 40. Thus, when pivoted inwardly, the rods 5| depress the necktie fabric so .thatit assumes the general'surface shape of strip .35.

' In order to commence the sewing of the necktie. theentire platform I6 is pivoted so that it overlies platform l5 and the strips 22 and 35 engage. the fabric being between them. However, it-is considered desirable in the form of the invention shown, to impale the fabric prior to rotation of the platform IS in order that the predetermined disposition of the fabric be not unduly disturbed or varied. Accordingly, means are provided to cause a series of needles 60, to penetrate the fabric at points inwardly of the recesses. Such needles will just barely penetrate thepfabric layers and will be received in complementary needle holes of the opposite strip. An elongated plate 6| supports all of the fabric impalingneedles .66inperpendicular relationship. When the plate 6| is raised, theneedles 60 rise accordingly in the needle holes 30 and upwardly in valleys 24into thecorresponding needle holes of the crests 36 of the strip 35. As illustrated in Figs. 4 and 5, the actionof the plate 6| is controlled by a rod 62 which rides in the eccentric slot 63 of a disc 64. Disc 64 is provided with a shaft 65 to which is connected a handhold member 66. A downwardly de endi b a 1 umm t he shaft 65- When handhold member 66 is rotated, the rod 62 will ride in slot 63 so as to cause the plate 6| and the needle 60 to be raised or lowered accordingly. The bearing lug 61 and disc 64 may be repeated at the other end of the machine as illustrated by the broken lines of Fig. 1 whereby the plate 6| will be properly supported at both ends.

Platform I6 is provided with a similar plate I6, handhold member 69 andvdisc duplicating the fabric impaling needle arrangement of the platform I5 and serving the same function for the other edge of the necktie. When the necktie elements have been shaped into the position of the respective strips 22 and 35 by the rods 4|,

and after the impaling needles have been driven into the fabric, the platform [6 is pivotally actuated so that the edges 15 and 16 of the necktie T (Fig. 6) are caused to be superimposed and intermeshed. At this time, the recesses 25 are brought into staggeredalignment with recesses 38 so as to form a guided pathfor the elongated needle which sews'the tie together. 'Thusfin'the form shown, the recesses '38, in cooperation with recesses 25, form a somewhat angular or slightly bent and substantially continuous path which guides the sewing needle adjacent the edges "15 and 16 which are disposed in inclined position relative to the platforms.

The elongated sewing needle '86 assumes conventional form, it being of a somewhat resilient steel so that it may travel a bentpath and yet be sufficiently sturdy to. be driventhrough such path while penetrating the fabric layers. The thread 8| which'isplaced through the eyeofth'e needle 60 serves to produce thestitches. Means for actuating the needle .86 are known, in.th 'e industry, but in any event, the n'eedlemay beactuated manually by providing a handhold memher on the rear end thereof. However, inthe ordinary commercial formof the apparatus the needle will generally be actuated by'mechanical driving equipment such as by the Needle Driving Apparatus for Sewing Machines" described in an applicationbeing filed vby me herewith, now Patent'No. 2,522,582, dated September 19, 1950.

,In order to discourage accidental displacement of the rods duringrotation of the platformli, and in any event, to enhance the function of such rods, spring may be effectively connected to shaft 42 so as to urge the rods into clamping,engagement with the fabric. Spring 86 serves a similar purpose for the rodsof platform I6.

' After the needle 80 has been reciprocated through the path formed bythe aligned recesses, andthe thread 8| has been sewn throughithe fabric layers, the sewing of Lthetie may be considered as effected. However, the disposition of the rods 4| and 5| prevents reverse pivoting [or restoration .of the platform l6 because the sewing thread is over such rods. Accordingly. 'rn'ea ns are. provided to remove the rods whilejthe platforms are in superimposed orengaged relationship. Bearing lugs 43 and are formed sets to ride over pinion racks 90 and 6| respectively. Thus, referringto Fig. 4,.a pinion wheel 92 is rotatably connected asby shaft to lug. ,When the wheel '92 travels across rack 80, the lug 4 3 is moved accordingly and the rods 4| may be withdrawn from withinthe folds 'oftheicorfrugated strips. Crank handle 84 actuates ,wheel 92 in effecting withdrawal of the rod structure 40. Crank handlei95 actuates-the wheel 36. of the platform l6 so as .to produce acorresponding withdrawal of .the rod structure 50. It will be understood, therefore, that aftersewing o'f'th tie has been effected, and prior toseparation of the platforms, the crank handles ,94 and 95 will be actuated so as to withdraw the rods laterally and out of the composite platform structure.

The rods having been withdrawn, the platform It will be returned to its position of horizontal alignment with platform I 5 so that the sewn tie and lining may be removed.

In Figs. 8 to is illustrated a preferred embodiment which permits shifting of the strip portions to accommodate different sizes of neckties. It is not considered desirable to shift the strips bodily because the relative dimensions and shapes of the tie portions change as the size changes. Accordingly, portion 26a of strip 22a is separated from strip 251:. at the line I00. Portion 25a is separated from portion 21a at the line "H. Each strip section is thereforemovable in relation to the remaining sections. Section 26a is formed with ears I02 having slots wherein are slidably maintained bolts I03. Platform I501. is formed with three slots I04 which are somewhat perpendicularly related to the slots of the ears I02. Accordingly, strip section 260. is not only capable of lateral adjustment in relation to platform or block I5a, but its capability of movement further includes a horizontal component whereby the section may be horizontally tilted in order to secure proper adjustment.

, In the same manner, ears I05 of central strip section 25a cooperate with the traverse slots I06 in permitting lateral adjustment of the central strip section. Adjustment of section 21a is effected by means similar to that of section 260..

It will be recognize that by virtue of the movability of the strip sections, the fabric impaling needles are neecssarily shifted in relation to the strips so that the needle holes III might ordinarily be misaligned. Accordingly, the platforms are formed with elongated and widened slots I I2 which accommodate movement of the needles commensurate with movement of the needle receiving holes by virtue of shifting of the strip sections. A modified form of impaling needle system is employed in that the impaling needles II5 are connected to enlarged holders I I6 which are spring loaded in tubes I I1, the spring H8 serving to depress the holder H6 in the tube II1 which is itself threadedly connected to the corrugated strip. Accordingly, the normal action of the needle H5 is to become withdrawn below the surface of the corrugated strip. Referring to Fig. 10, if the bolt I20 is loosened at the same time as the other bolts securing strip 21a to the platform, thestrip may be suitably shifted laterally or inclined to the longitudinal axis of the supporting platform. The needle holding tubes II1 will likewise shift within the slots H2 of the platform.

Modified means are provided to actuate the needle holders II6 for the purpose of either impaling or releasing the tie fabric. Thus, the handhold member I25 is connected to a shaft I26 which rotates or oscillates the eccentric wheel I21. A depending plate I28 serves as a bearing for shaft I26 and is formed with two vertical slots I29 and I30. Pins I3I and I32 are arranged to ride in such slots and such pins are disposed on the top and bottom of the eccentric wheel I21. Integral with pins I3I and I32 is the elongated plate I33 which is arranged to serve as an abutment for the needle holders IIB so as to prevent their displacement from within the tubes II'I. a V

When handhold member I25 is actuated soas to bring the higher portion of wheels I21 into an upward position, the pin I3I is raised as shown in Fig. 9 and the plate I33 israised accordingly so that the needle holders IIG are forced upwardly against the action of the springs H8, and the needles H5 are then caused to impale the fabric seated on the corrugated strip. If the handheld member I25 is rotated another half turn, the pin I3I is permitted to descend so as to permit the holders I I6 to be actuated upwardly by springs IIB so as to cause the needles to be withdrawn.

If desired, indicia lines I35 are formed-on the platform surfaces so as to assist in the matched adjustments of the opposing strip sections. However, it is proposed that such-strip sections may be adjusted in situ as a test sewing needle is being directed through the aligned recesses; In other words, after approximate and preliminary adjustment of the opposed strip sectionshas been effected, the platforms may be superimposed and a test elongated needle may be applied through the formed guide path. If end strip section 35a is not in proper alignment, its holding bolts may be loosened and the stripshifted until the elongated needle travels freely through the engaged strips. In order that the holding bolts maybe actuated, their position on platform [6a is reversed in that the bolt heads appear on the underside. To permit rotation of thebolts I20 so as to loosen the strip sections to permit a required adjustment, the bolts are provided with nuts I36 which have reduced portions I31 of rectangular form and which enter the slots in the platform, such as slots IBM... Accordingly, when the bolt head is rotated, the nut I36 will remain stationary so as to effect loosening of the strips in relation to the supporting platform and their adjustment thereon.

The operation of the apparatus will be under-' stood from the foregoing description of its components. It will be understood that inasmuch as the recesses occupy a predetermined position, variations in the width of the tie T cannot affect the size of the tie even if it is accidentally precut to over-size dimensions. After the tie has been sewn in the manner heretofore described, it is turned inside out so as to be in its wearing position. If, then, the tie has been accidentally cut over-size or is in some other manner distorted as to width, such distortions or variations will occur on the inside of the tie so that the tie will always assume the same predetermined shape, as long as the tie fabric and lining are initially pre-set so as to cover the recesses in the corrugated strips. The presence of the pivots I8 practically assures the proper guiding path for the needle as predetermined because the platforms cannot become mismatched to any important degree. Furthermore, the pre-positioning of the tie elements is of importance in facilitating the operation of the device and in decreasing the number of rejects or discards due to improper initial feeding of the tie to the structure or in shifting thereof after having been preset. The controlled operating position of the platforms is further useful in forming an accordingly controlled needle guide path so that recesses are properly aligned and needle breakage is less frequent.

An important feature of the instant invention is the fact that when'the tie fabric has been initially positioned on the strips as illustrated, it is automatically in proper folding position;

and such folding is automatically accomplished when the platforms are pivoted to bring together the edges of the tie fabric.

InFigs. 11 and 1-2 is illustrated a further modifled embodiment wherein the rod structures are substantially eliminated. Thus-shaft I50, which is pivotally supported in the bearings I51 and I52 has connected thereto three elongated bars, two of which are illustrated, viz I53 and I54. Bar I53 is adjustably connected to arms such as arms I-55a which in turnare connected to the shaft I50. Bar I53 serves the top strip section 26b in holding down the lining and tie fabric edges while they are penetrated by the impaling needle in needle hole III. Since strip section 26b is shiftable as was its counterpart in Fig. 8, bar III is likewise made shiftable in order'that its needle holes I51 may be properly aligned with those of thestrip 2 Gb. The needles of strip 261) are actuated in the same manner as those of 26a heretofore described. Bar I54 is likewise connected to shaft I50 by arms I55 and I56 and serves strip section 21b.

Bar I54 is rendered adjustable by the provision of slots I58 and I59 in the connecting arms while further slots I60 and I'Iil are formed adjacent the respective ends of the bar I54. Nuts I62 and I63, when tightened, clamp the bar to the connecting arms, and when loosened, permit adjustment thereof so that the respective needle holes may become aligned. The nuts are disposed at the upper side of bar I54 so as not to rest upon'strip 21b when the bar I54 is applied thereover. In actual practice, the bar I54 may be swung over strip section 21b and may then be adjusted untilthe respective needle holes are properly aligned. Of course, needle holes I51- may be made larger than shown or somewhat oval as were needle holes- H2 in order to provide a tolerance of adjustment.

In the same manner, bar I65 serves strip section 35b and bar I56 serves strip section 350. Referring to Fig. 12, the tie lining and fabric will first be placed upon the strip sections as illustrated in Fig. 6, and the bars I53, I54, I55, I56 et seq. will be swung thereover so as to hold the tie lining and fabric down. At this time, the needle actuating plates will be operated so as to cause the needles to rise and impale the lining and fabric in the proper position. Thereafter, the bars will be swung outwardly and the platforms or blocks will be pivoted around the pivot I69 so as to bring the parts into superimposed relationship illustrated by the broken lines of Fig. 12. This crimps the fabric edges and produces the needle guide path I10 whichp ermits reciprocation of the elongated needle-for sewing of the necktie. Spring III is prov-idedto maintain bars I65, I-66et seq. in outwardly supported position when the platforms are superimposed asillustrated in Fig. 1-2.

In Fig. 13 is illustrated a third modification which may accommodate neckties-of differing sizes without requiring shifting of the strip sections. Thus. strip H is formed as was strip 22 of Fig. 1- but with its topend section I16 provided with three rows or sets of recesses. The-center row of recesses III: is similar to the recesses of the first embodiment while recesses- I 18' and H9 are aligned on both. sidesthereof converging near the commencement of central strip; section I80. All the strip sections, including lower strip section I8 -I, are integral. The-strip sections I80 and. IBI are not provided with a plurality of recess lines because those sections respectively represent. the neckband and narrow end of the necktie andare accordingly not considered of importance. The front portion of the tie is the most important portion thereof and itis the size of such'front portion that is-accommodated by the plurality of recess rows. If a necktie having a narrow front portion is to be sewn, row I19 will be employed. These recesses will engage, of course, with the recesses I82 of the opposite strip as hereinabove described, On the contrary, a necktie having a'wide front portion will employ the recesses I18 and I 83. Selection of the desired rows of recesses is accomplished by shifting of the elongated sewing needle as illustrated at the top of Fig. 13.-

An advantage of avoiding shifting of the strip sections is the fact that the impaling needle holes I84 will alwaysbe in the same position so that the holding bars, not shown, need-not be shifted.

In any ofthe-foregoing embodiments, the impaling needle function is considered to be of importance because the tie and lining will be .securely maintainedin place during the folding processnotwithstanding different weaves of fabric and other variable characteristics thereof. Further, in order that the force of the driven needle does not disturb the aligned or engaged strips, a lock such as latch liaof'Fig. 1 may serve to maintain the platforms properlysuperimposed during the sewing process.

One of the difliculties in the operation of previous necktie sewing machines-has-been the requirement of skilled labor. It was necessary in many cases to fold the tie accurately and apply the lining insuch a way that the necktie elements were properly sewn through the action of the machine. In using. the present invention, the operation is almost foolproof in that the elements need merely be laid down in position on the strips, the mach-ineclosed and the needle actuated. The strips themselvesand the recesses formed therein dictate the position of thetie elements so that relatively unskilled labor is required therefor. If a tie lining has been cut oversize. it will nevertheless be sewn to the correct size as described above. It is further possible to utilize linings which have been cut slightly undersize by manually pulling the fabric transversely until the operator is certain that'the: edges have passed the-rowsof recesses. Only a slight extension is possible forthis purpose, but other-' wise unusable fabrics may often beusefully employed instead of being discarded.
