1 Claim. (01. 11z-174) This invention relate to a machine for making neckties and more particularly to assembling, folding and sewing together the necktie parts.

Necktie sewing machines in common use today, which are capable of inserting slip stitches, require the services of an operator to first fold the necktie materials into proper superimposed position by hand before commencin he sewing operation. In some cases a number of necktie materials are first pinned together in proper assembled relationship in one operation and are then sewn together in another completely distinct operation at a position remote from that where the fabrics were assembled. This procedure has been followed with the aim of cutting down the time consumed in folding necktie masame station in the machine throughout all of 1 said operations.

Another object is to provide a simplified necktie making machine which will reduce the length of time and cost of making neckties by machine.

A further object is to provide a machine which will fold and sew necktie materials in one operation and in one position.

A further object is to secure a, more accurate registration of folded necktie blanks and necktie linings with respect to one another and with respect to a needle inserting a slip stitch through said fabrics.

Other objects and features of the invention will appear as the description of the particular physical embodiment selected to illustrate the invention progresses.

Fig. 7 shows a necktie lining and necktie blank sewn together. 7

Referring to Fig. 1, the frame In supports a. corrugated pleating bed I I. At one end of the pleating bed I I are formed several corrugations l2 which are somewhat smaller in size than the corrugations 46 making up the rest of the pleating bed. A second pleating rack I3 is pivotally mounted on the frame l by means of arms. l4 pivotally connected to lugs l by means of pivot pins I6. The lugs l5 are fixedly connected to the frame ID. A foot pedal I1 is also pivotally connected, by mean of shaft l8, to the. frame ||l of the machine, and by means of the connecting rod 41 impartsraising and lowering movement to the upper pleating rack l3. The spring l9 serves to hold the foot pedal I1 and upper pleating rack l3 normally in elevated position and yields under the foot pressure of an operator to permit the upper pleating rack to be pulled down upon the lower pleating rack, and by co-action of the corrugations 46 with corrugations 48 pleat necktie materials positioned on the lower pleating rack. A slot is formed across the corrugations of the lower and upper pleating racks II and I3 which is adapted and arranged to receive, guide and support a sewing needle 2|. The sewing needle 2| is fixedly connected at one end to the sprocket chain 22. The endless sprocket chain 22 is carried by sprockets 23 and 24, which are fixedly mounted on shafts 29 and 28 respectively. Shafts 29 and 28 are freely mounted in a suitable bracket 25 fixedly secured to the frame Ill, A crank arm 26 having a crank handle 21 is fixedly connected to the shaft 28 and serves, when actuated by the operator, to impart forwarding and retracting movement to the needle 2| by means of the sprocket chain 22. The upper run of the sprocket chain 22 is guided between support bars 53 and 54. The upper bar 53 has a longitudinal slot 55 for guiding and supporting the needle 2| as it is forwarded and retracted by the sprocket chain 22.

A needle guide 30 having a countersunk opening 3| receives and guides the needle 2| into'slot 2|] when the needle is forwarded by the operator.

' To facilitate positioning of the necktie lining and necktie blank with respect to each other prior to folding, a lining guide 32 (Fig. 4) is provided ud acent to the lower pleating rack so that the operator can place the edge 33 of the lining against the edge of the guide 32, guide 32 being secured to a plate Hill supported by frame Hi. A slid-able folding plate 34 has slide strips 35 fixedly connected thereto which are adapted to slide in slots 3'6 which are formed in the rectangular block l] attached to the plate I02 secured to the top of frame ID to restrict the plate 34 to a predetermined sliding path of travel. Adjustably secured to the plate 34 are necktie blank guides or gauge members 31 which have slots 38. A screw 39 passes through each of the slots 38 and is threaded into the plate 34. By loosening the screws 39, guide members 31 may be moved backward and forward and also turned about screw 39 so that they may be accommodated or adjusted to guide various shapes and sizes of necktie blanks.

A knob 40 is provided for the operator to move the holding plate 34 backward and forward to fold and hold the necktie blank. A back plate 4| is provided for holding the necktie blank in position with respect to the lining blank prior to the folding operation. The folding edge 42 of back plate 4| is shaped to impart the proper folding line to the necktie blank N and lining guide.

Extensions 49 of the plate 4| are pivotally mounted in rectangular sliding blocks 50 which are adapted to slide in conventional slide-ways ormed in the inner lateral faces of members 5|. The members5| are secured to the plate I00. Suitable torsion springs 52 are provided to press the plate 4| downwardly and thereby impart a clamping action to back plate 4| when it is placed over the lining and necktie blank. Back plate 4| is pulled forwardly over the lining and necktie blank while at a slightly elevated angle and is withdrawn after the folding operation along a horizontal path of travel to avoid disturbing the necktie fabrics.

The operation of the machine may be briefly described as follows: With the upper plate rack l3 in elevated position, the folding plate 34 and back plate 4| in withdrawn position, and the needle 2| in retracted position, an operator places an unsewn lining blank over the lower pleating rack so that the edge 33 of the lining is positioned against the fixed lining gauge 32. The operator then positions the outer edge of the necktie blank N against the guides 31 and lays the rest of the necktie blank over the lining L already positioned over the pleating rack II with its edge abutting guide plate 32 as shown in Fig. 4.

he operator now grasps back plate 4|, holding it in raised position, and moves it forward, placing it down over the lining L and necktie blank N so that the edge 42 thereof is placed where the fold line of the necktie blank is to be. The operator then grips knob 40 and pushes the folding plate 34 forward in the direction'indicated by the arrow in Fig. 4 to fold the necktie blank along the fold line formed by edge 42.

After this operation, the operator withdraws back plate 4|, leaving folding plate 34 holding aaeaesc the folded necktie blank and lining in overlapped and superimposed position. Next, the operator steps on the foot pedal l1, bringing down upper pleating rack i3 upon lower pleatin rack H so as to pleat the overlapped and positioned necktie fabrics. Then by means of crank handle 21, the operator forwards needle 2! through the pleated necktie fabrics to position 43, shown in Fig. 1, the thread T having been previously drawn from the spool supported on the holder 44 and passed through the guide 45 and threaded through the eye of the needle 2|. The operator then takes hold of the free end of the thread and holds the same while retracting the needle by turning handle 21 in the opposite direction, thus leaving a thread in the pleated necktie materials. After the needle has been withdrawn, the thread is severed adjacent member 3| by suitable shears or a knife. At the completion of the sewing operation, the tie is turned inside out so that the necktie blank will be on the outside of the lining.

It is not always necessary to incorporate a necktie lining with a necktie blank and sometimes neckties are made without linings. Applicants device can be used for making neckties either with or without linings without requiring any structural changes to be made in this machine.

The term "slip stitch, when used in this specification and claims, is intended to mean any conventional resilient stitch suitable for use in sewing necktie materials together which is capable of being stretched longitudinally.

The invention above described may be varied in construction within the scope of the claims, for the particular device selected to illustrate the invention is but one of many concrete embodiments of the same. The invention therefore is not to be restricted to the precise details of the structure shown and described.

What is claimed is:

In a sewing machine, the combination with means for supporting an outspread necktie lining and an outspread necktie fabric, said necktie fabric and lining being associated in superimposed relationship with each other with one longitudinal edge of said necktie fabric extending along a longitudinal axis of said lining, of mechanism for folding the fabric on said means to lap one of its longitudinal edges upon the edge thereof arranged to extend along alongitudinal axis of said lining, said means including a member having a corrugated face adapted to support the lining and folded fabric, a device having a corrugated face coacting with the corrugated face of said member to pleat and hold the lining and folded fabric supported on said member in pleated condition, a needle adapted to be passed through the pleated fabric and lining while held by said member and device to stitch the same together, and mechanism for operating said needle while said fabric and lining are held in pleated condition, to stitch the pleated fabric and lining together.
