In Sweden June 21, 1934 3 Claims.

This invention relates to neckties of the kind wherein a strip of? metal, celluloid or other durable material is secured to the neck-portion of a fabric tie, so that the said strip, by diminishing friction, facilitates the sliding of the tie on or through the collar.

The primary object of the invention is to provide improved means for securing the said strip to the fabric portion or portions of the necktie. The invention also comprises certain improvements in the strip itself to be disclosed in detail hereinafter.

The invention will now be described with reference to the accompanying drawing, in which: l

Figures 1 and 2 illustrate a partly sectioned elevation and side view respectively, o-f one embodiment of apparatus according to the invention. f

Figures 3 and 4 are elevations, drawn to a larger scale than Figures l and 2, of pressing tools included in the said apparatus.

Figure 5 is a broken plan view of one embodiment of the str-ip. r

Figure 6 is a vertical section of the strip shown in Figure 5.

Figures 7, 8 and 9 show a plan view, crosssection and longitudinal section, respectively, of a connecting device intended to be used for securing the strip to the fabric of the tie.

Figures 10, 11 and 12 illustrate different stages in the process of folding the connecting device over the strip and fabric.

Figure 13 shows the necktiey in final condition on a reduced scale.

Figures 14 and 15 are a cross-section and a plan View respectively of another embodiment of the connecting device.

Figure 16 is a view similar to Figure 12and illustrates the connecting device according to Figures 14 and 15 secured to the fabric of the tie.

Figure 17 .shows a part of the necktie provided with the connecting device illustrated in Figures 14 to 16.

Figures 18 and 19 are modified embodiments of the pressing tool.

Figure 20 illustrates a cross-section of a connecting device after having been closed by either of the tools according to Figure 18 or Figure 19.

Referring to Figures l to 4 reference a designates a support or bracket, carrying a substantially horizontal shaft b and two approximately vertical spindles c, d. Shaft b carries two swingable levers e above the spindles c and d. Each of the levers has a cam e1 acting to move the spindles vertically, against the action of spring means c1, d1, whenthe levers are pressed downwardly. On releasing the levers the spindles are returned upwardly by the springs. yIn order to avoid rotation of the spindles each of them may be guided by a pin h projecting through a slot g formed in the spindle guide, as shown, or by any other means.` At their lower ends the spindles carry pressing tools y', k, which, in the depressed position of the spindles, enter a groove Z in a die i.

The shape of the twol pressing tools is shown in Figures 3 and 4, from which it will be seen that tool lc has two internal pressing surfaces k1 inclined to the bottom of groove l, while tool 1:1' has a pressing surface il substantially parallel to the said bottom. l

The apparatus described is designed to be used in securing a. strip of metal, Celluloidl or a similar material to the neck portion of a tie. The strip may either be secured at the inner side of the fabric neck band of a single piece tie, or may entirely replace such fabric neck band, in which latter case the tie comprises two separate pieces of fabric, secured each to one end of the strip. Only the latter method will be described, but it should be clear that the invention also comprises methods wherein the strip is secured to the neck band of a single piece tie.

Figure 5 illustrates one embodiment of the strip m. I prefer to make the strip of a relatively thiny sheet of stainless steel and to corrugate its surface (Figure 6) but it will be clear that the strip could also be made smooth (Figures 16 and 17) and of any other material. Corrugating the strip, however, gives it amore beautiful appearance and makes it better able to resist undesired deformation; moreover the friction between the strip and the collar is reduced in this way, because the strip can slide more easily on the rounded ribs of the corrugations.

At each end portion the strip may be provided with teeth n, or the like,` along a length thereof having reduced width and preferably terminating at a slight distance from the ends. According to .one embodiment yof the invention the teeth n may incline inwardly from the ends of the strip.

In securing the strip m the ends of the fabric pieces are fitted over or placed close to the part of the strip ends carrying the teeth n, and then a U-shaped clamping member p (Figures 7 to 9) having the same or approximately the same Width as the strip, is fitted outside each fabric piece, so that the flanges of the clamp press the fabric o against the teeth it (Figure 10). Now the tie, with strip and clamps, is placed in the groove Z and the tool k is moved down to bend one of the clamps p to the shape shown in Figure 11. The tie is then slipped forwardly in the groove l to the tool j which when operated, presses the flanges of the same clamp down on the fabric (Figure 12) to grip the latter' firmly and secure it to the strip m. Then the other clamp is treated in a similar way.

Preferably the clamp has the same length as the toothed part n. In order to secure a firm gripping action the anges of the clamp may also have teeth as indicated at 111. Furthermore I prefer to provide the short sidesV of the clamp with upwardly bent parts p2 (Figure 9) enabling the clamp to fit tightly to the fabric and the strip.

The space between the tools il', lc may be the same as the distance between the clamps on the strip. In this case the clamp at one end of the strip may be treated by tool 7c at the same time as the clamp at the other end of the strip is treated by tool y'.

Figure 13 shows the finished tie, illustrating that the clamps p at the ends of the strip m have substantially the same width as the strip so that the edges of the clamps close tightly to the corresponding edges of the strip.

The length of the strip should be sufficientlyl short to leave sufficient lengths of fabric free outside the collar for making the usual knot.

The apparatus may be modied in several ways without departing from the spirit of the invention. Thus it is not necessary to bend or close the clamp to its final shape in two stages. If the clamp be made with suficiently short flanges only one pressing tool is required and this may take the form diagrammatically shown in Figure 18. In this case two opposite edges of the lower surface of the tool have grooves or recesses s, preferably with rounded bottoms, adapted to bend the flanges inwardly and press them against the fabric in one single pressing operation. In

, using such tool the bent clamp assumes in cross section the appearance shown in Figure 20.

Even if it is desired to bend the clamp in two stages, only one single tool is required, if the transverse section of said tool be such as first to give the clamp the shape shown in Figure 11 l and then to bend the flanges down to the position shown in Figure 12. Moreover it is not necessary to provide two levers e even if two separate tools are arranged; instead there may be one single lever furnished with two or more cams coming in operation successively.

If desired the cams el can be mounted on a rotating shaft or shafts, in which case the apparatus can be power driven instead of being manually operated.

It is also possible to give the apparatus the form of a pair of tongs or the like', having jaws similar to the tools now described, by means of which the flanges of the clamps are closed.

In some cases it may be preferable to have the ends of the clamp flanges turned slightly inwards (Figures 14 and 16) and to bevel or round off the corners of the flanges (Figure 15) thereby affording a rmer gripping action.

According to a further embodiment I may fit a thin sheet r (Figure 16) of metal or other material between the flanges of the clamp before finally closing the latter, the object being to prevent the fabric of the tie from being injured by the clamp. The appearance of a portion of a finished necktie provided with such sheet is shown in Figure 1'7, also illustrating the use of .a smooth strip m instead of a corrugated one.

When using the sheet 7 the pressing tool shown .in Figure 19 may be employed for xing the parts together. According to this embodiment the tool comprises one external member t, provided at the bottom with recesses s for closing the clamp, and an inner member u slidably arranged within the member t, and acted upon by a spring 1J. On pressing the member t down towards the necktie the member u first engages the sheet 7 and presses it tightly against the said necktie, Whereafter the member t continues to descend until the iianges of the clamp are ,turned over to the gripping position by the recesses s (Figure 16). In order to ensure that the rounded corners (Figure 15) of the clamps are pressed tightly to the sheet r the bottom of the member t may have small projections acting upon the said corners when the tool is depressed.

If desired the clamps and/or the sheet r may be corrugated.

The teeth n may be replaced by suitable projections or rough surfaces.

When it is desired to secure the strip m to the fabric neck portion of a single piece necktie the strip is placed on the inner surface of the neck portion, the edges of the fabric portions are fitted close to the longitudinal edges of the end por'- tions of the strip and then the clamps p are bent over the strip in the way described to firmly press the fabric against the edges of the strip. In this case the clamps may extend over greater lengths of the strip than in the embodiment illustrated in the drawing.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

1. A method or securing a strip of resilient material to the neck portion of a necktie, comprising the steps of tting the fabric of the tie over the end of the strip, applying a subfstantially U-shaped clamping device outside the fabric at the said end of the said strip, tting a sheet of material, having approximately the same width as the interior width of the clamp, between the flanges of the said clamp, and bending the flanges of the clamp inwardly on to the sheet to secure the fabric and the strip rmly together.

2. A necktie provided at the neck portion with a strip of resilient material having toothed or serrated longitudinal edges at each end.

' 3. A necktie provided at the neck portion with a strip of metal the whole surface of which is corrugated longitudinally on both sides.
