METHOD AND MEANS FOR SEWING AND SHANKING BUTTONS Filed Feb. 25, 1963 2 Sheets-Sheet 2 INVENTOR Joseph So/anko ATTORNEY United States Patent 3,213,816 METHOD AND MEANS FOR SEWING AND SHANKING BUTTONS Joseph Solanka, Baltimore, Md., assignor to The Londontown Manufacturing Company, Baltimore, Md., a

corporation of Maryland Filed Feb. 25, 1963, Ser. No. 260,648 7 Claims. (Cl. 112-265) This invention relates to a method and means for shanking buttons and is a continuation-in-part of my earlier application Serial No. 119,916 filed June 27, 1961, and now abandoned.

As conducive to a better understanding of the instant invention the following background material is set forth. In the garment industry it is conventional, in sewing a button or the like on a piece of fabric or a garment, to space the button therefrom and after the sewing has been completed to wrap a thread around the connection between the button and the fabric to provide a shank. This shank strengthens the attachment and facilitates buttoning and unbuttoning the garment. The conventional shanking procedure is relatively time consuming and expensive and many methods and means have been suggested heretofore in an effort to improve thereon. It has been suggested, for example, to provide a spacer or a washer-type element to be positioned between the fabric and the button and having openings corresponding to the conventional apertures in the button. Such means have either been uncommercial because of undue expense in manufacture and in handling or because the relatively loose fit of the aforementioned element around the thread securing the button to the fabric has caused relative movement between these parts and friction on the thread, resulting in excessive wear thereof and frequent loss of buttons from the garment. Others have suggested sewing directly through a penetrable spacer element but this has caused great dulling of the sewing needles and excessive expense in handling.

It is therefore a primary object of the instant invention to provide an improved method and means for performing the shanking operation.

Another object of this invention is the provision of a shanking method which eliminates the necessity of a separate shanking machine and which results in a substantial saving of thread during the manufacture of a garment.

It is a further object of the instant invention to provide a method for shanking buttons which is relatively quick and easy to accomplish and requires little skill on the part of the operator.

A still further object of this invention is the provision of a shanking method which results in an improved final product wherein the button is spaced from the fabric by a resilient band means tightly surrounding the thread connecting the button to the fabric.

Another object of this invention is to provide a shanking method resulting in a product of high uniformity and good aesthetic appearance.

Yet another object of the instant invention is the provision of an improved means for shanking buttons, which means is reliable and efiicient in operation and relatively simple and inexpensive to manufacture and utilize.

Another object of this invention is to provide a shanking means comprising a holder having an opening therethrough for the passage of the threads connecting the 3 ,Z l 3 ,8 l 6 Patented Oct. 26, 1965 button to the garment and a supporting means extending around the opening to retain a resilient band means during the sewing operation, wherein the holder is frangible so that it may be easily broken and removed, leaving the resilient band means in relatively tight engagement with the button threads.

A still further object of this invention is to provide a shanking means of the type described wherein the supporting means is comprised of a substantially continuous flange means adapted to retain a small rubber band or the like therearound during the sewing operation.

Yet another object of this invention is the provision of an improved shanking means wherein a plurality of pins are disposed in spaced relationship about an opening therein to support and retain a resilient band means thereon during the sewing operation.

Other and further objects reside in the combination of elements, arrangement of parts and features of construction.

Still other objects will in part be obvious and in part be pointed out as the description of the invention proceeds and as shown in the accompanying drawings wherein:

Like reference characters refer to like parts throughout the several views of the drawings.

Referring now to the drawings, particularly FIGURES 1 to 3, one form of the shanking means or holder of therein and an upstanding supporting means 2d disposedabout the opening 24. A substantially V-shaped notch 28 is diametrically defined in the base portion 22 on opposite sides of the opening 24 and a continuation 30 of the notch 28 separates the supporting means 26 into two substantially semi-circular flange means 32. The notch 28 and its extensions 3% provide a weakened line to render the holder 20 readily frangible for a purpose to be described further in detail hereinafter.

A resilient band means 34, for example a small rubber band or the like, is readily secured in stretched relationship over the free end of the supporting means 26 surrounding the opening 24.

Another embodiment 40 of a holder according to the instant inventive concept is shown in FIGURES 4 and as having a circular base portion 42 with a central opening 44 therethrough. In this modified form, the supporting means is comprised of a plurality of pins 46 or the like secured in spaced relationship about the periphery of the opening 4-4 to retain a resilient band means 48 thereon in a manner similar to the holder 20. A V- shaped notch 50 or other such weakening line is defined in the base portion 42 to facilitate rupture of the holder 40 to release the resilient band means 48 in a manner to be described further hereinafter.

Another embodiment of a holder in accordance with this invention is shown generally at 60 in FIGURE 6 and comprises a substantially square base portion 62 having a circular opening 64 defined therethrough and a plurality of pins 66 or the like disposed in spaced relation around the opening 64 to retain a resilient band means 68 thereon. A notch 70 renders the holder 60 frangible in the same manner as the holders 20 and 4-0 described hereinbefore.

It is to be understood that the holder of the instant invention may be formed of any relatively rigid but readily frangible material such as plastic or the like and that the particular size or shape of the base portion, opening or supporting means is not critical to the instant inventive concept.

The use of the shanking means or holder, preferred embodiments of which have been shown and described hereinbefore, will now be set forth with particular reference to the embodiment of FIGURES 1 to 3 and to the improved method of shanking as shown in FIGURES 7 to 14.

A portion of a garment or a piece of fabric to which a button 80 is to be secured is designated by the reference numeral 82. A stay button, used in the manufacture of more expensive garments, is shown at 84 and may be utilized in the method of the instant invention if desired. The holder 20, with the resilient band means 34 supported thereon in stretched relationship, is placed over the fabric 82 in a position where the button 80 is to be sewn and shanked. The button 80 is then supported on the holder 20 and the sewing operation is performed, passing threads 86 in the conventional manner through the apertures (not shown) in the button 80 and in the stay button 84, if the latter element is utilized.

It is to be understood that the holder 20 may be placed with the bottom of the base portion 22 on the fabric 82 and the button 8t) supported on the free end of the supporting means 26 as shown in the drawings, or the holder 20 may be inverted so that the free end of the supporting means 26 is in contact with the fabric 82 while the button 80 is supported on the bottom of the base portion 22.

The button 80 is then pulled upwardly as shown in FIGURE 9, if necessary, in the direction of the arrow 88 to facilitate grasping opposite edges of the holder 20 by the fingers 90 of the operator. This will pull a portion of the fabric 82 upwardly through the opening 24 in the base portion 22 of the holder 20 so that the holder 20 may be broken along the notched weakening line 28, 30 as seen in FIGURE 10. The broken portions of the holder 20 will then be removed, allowing the resilient band means 34 to slip off the supporting means 26 and remain in place in a relatively tight engagement with the threads 86 as shown particularly in FIGURES 10 and 14.

It will now be seen that there is herein provided an improved method and means for shanking buttons which satisfies all of the objectives of the instant invention and others, including many advantages of great practical utility and commercial importance.

Since many embodiments may be made of this inventive concept, and since many modifications may be made of the embodiments hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.
