6 Claims. (Cl. 112-262) This invention relates to button holding and feeding means, and more particularly to self-shank button holding means, and still more particularly to methods for holding buttons for sewing the same.

This invention particularly deals with button holding means for self-shank or shankless buttons described and claimed in an application entitled Self-Shank Buttons, Serial No. 584,025, filed May 20, 1956.

In the application aforesaid, there is described and illustrated a self-shank button generally of lenticular body, having a transverse aperture open to each side edge of the button substantially in parallelism with and between the front and rear faces of the buttons, to provide a thread opening and an open groove on the rear face to one side of the thread aperture having utility for purposes here de-v here described The contour, shape and semi-spheroidal faces introduce a problem in handling these buttons for effective sewing in commercial button sewing operations.

Accordingly, it is an object of my invention to provide a button holding device securely to clamp the button whereby effective stitching operations may be performed quickly and facilely, and to accomplish, in a most efiective manner, a relationship between the rear face of the button and the fabric to which the button is sewn, which relationship pre-determinedly integrates the button to the fabric from which it is supported by the threads.

Still more particularly, it is an object of my invention to provide a button holding and clamping and button feeding device whereby stitching operations may be carried out quickly, including the feeding of buttons seriatim to known clamps of button sewing machines, whereby the benefits of a self-shank button of partispheroidal or lenticular body may be achieved economically without the awkwardness incident to the handling of. such buttons.

Still more particularly it is an object of my invention to provide a mitten for sewing shankless buttons with economy, making the use of such buttons commercially practicable.

To attain these objects and such further objects as may appear herein or be hereinafter pointed out, I make reference to the accompanying drawing, forming a part hereof, in which,

Figure l is a perspective view of the holder;

Figure 2 shows the holder supporting a button in position;

Figure 3 is another embodiment whereby a series of buttons may be held in position;

the shank protrudes from the rear face in the form of a semior parti-spheroidal contour of such magnitude as may be considered a shankless button. In this latter type of button construction, a transverse thread aperture extends in a plane substantially in parallelism to the primary plane of the front and rear faces. A specific embodiment of such button is more clearly illustrated in the application of Sidney Emsig aforesaid.

The self-shank button in accordance with said application particularly includes an open groove on the rear face, exposing a pair of ridges to one side of the thread aperture and preferably at right angles to the axis of the aperture.

I have found that this button, with all its desirable attributes, may be handled economically despite its awkwardness, due to its general spheroidal contour, by a button clamp and holder in accordance with my invention, to provide novel and economical sewing methods. For this purpose reference is made to Figure 1 wherein the button holder 10 comprises spaced branches 11 and 12, resiliently joined by a loop 13. The branches 11 and 12 are substantially in parallelism and are constituted of spring wire resiliently to urge the branches 11 and 12 in relation to each other, thereby forming spaced clamping members. The branch 11 may terminate in a dull edge 14. The branch 12 is preferably extended beyond the end 14 and terminates at 15 in a fabric piercing end or needle point.

With a construction as shown, a lenticular button B may be held between the branches 11 and 12. Employing the shankless button in accordance with the Emsig patent application aforesaid, it will be observed that I may extend the button to have the branch 12 guided within the open groove 16 transverse to the thread apertures 17. The branch 11 clampingly retains the button oriented with the thread aperture at right angles to the branch 12, which acts as a guide slidingly to hold the button along the length of the branch 12 under the biasing influence of the branch 11 on the front face 18. The rear face 19 of the button is thereby exposed and spans the branch 12, which acts as a rear face contacting clamp member.

With such asembly, the button 13 may be facilely and quickly handled without awkwardness, extending the thread apertures to one side of the loop 13 at a sufficient distance so that the assembly may be manipulated by the loop 13. In this form, the holder may be used to locate the button on any fabric F, as shown in Figure 4, piercing the point 15 and locating the rear face 19 adjacent the portion of the fabric at which the button is to be sewn, with the thread aperture 17 oriented transversely to the holding clamp 12.

Stitching may then be efiected through the aperture 17 and about the rear clamp member 12. When an adequate number of needle and thread passes has been extended through the thread aperture of the button and fabric, the holder 10 may be removed without relaxing the effectiveness of the thread passing through the button.

Figure 4 is a perspective view illustrating the method The form of construction described provides the meansfor handling of these awkwardly shaped buttons, par-.

7 ticularly small sizes of shankless or self-shank buttons without hazard and with speed making their use eco-. nornically possible commercially. Likewise, the clamp may be used temporarily to tack a number of buttons to. a garment, thereby assuring a predetermined location of buttons on a garment.

The employment of the button holder having a clamp member of a dimension interfitting the groove on the rear face of the button, particularly fitting within the confines of the groove, permits stitching about the rear face contacting clamp member without relaxing the thread which holds the button in position when the clamp member is removed, thus permitting an effective section or quantity of fabric to be engaged by the stitch and thereby positioning the button uprightly on the fabric, as well as in a close contacting relationship not previously experienced with self-shank buttons.

While I have shown and described a button holder for'selfshank buttons which provides the novel means for handling one button at a time, I may provide a holder in which a series of buttons to be affixed to a garment are grouped and handled simultaneously. A construction for this purpose is illustrated in Figure 3 wherein the holder 100 has a front face clamp member 11:: joined to a rear face wire clamp member 12a, by an intermediate loop 3.3, the members are of a length to hold a plurality of the self-shank buttons, as previously described. In the illustration, six buttons are shown guided along the wire clamp member 12a. As in the prior embodiment, the rear face clamp member 12a is provided with a needle point 15 where temporary location and contact on a fabric is found desirable. The assembly of a plurality of buttons may be used as in the prior embodiment, iocating the thin-wire rear-face clamp member in the open groove on the rear face of the buttons. The buttons may be slid progressively along the wire 12a after each sewing operation, the thread aperture being oriented thereby and, in this specific form, transversely to the clamp member 12a, while permitting access alternatively to the thread aperture and piercing the fabric as each stitch is made about the exposed ridges to each side of the groove 16, previously described,

As each button is sewn in position, the holder with the remainder of the buttons thereon may be removed without relaxing the tension of the thread, holding the button on the fabric in the manner previously described. Thus, a series of buttons may be progressively slid along and from the rear face clamp member 12a, while holding the button in contact with the fabric by the stitches.

While I have described and illustrated a button holder for carrying out a stitching operation by hand, the holder may be employed with existing button sewing machines to facilitate a speedy feeding of the shankless button in existing button sewing machines. 7

In the illustration, the base will be recognized as the base of a Singer No. 175 button sewing machine wherein the usual work clamp arm 31, under the influence of the sewing machine treadle, has mounted thereon a machine button holder 32, capable of moving toward and from the work supporting anvil 33. In opposed position to the button holder 32 there is shown a button finger 34 which terminates in a seat or socket 35 of generally concave outline to receive, centrally seated thereon, the front face 18 of a self-shank button.

With a holder such as described in Figures 1' and 3, buttons B, particularly those arranged in series in edgeto-edge contact as shown in the embodiment in Figure 3, may be used to feed a single button in oriented position with respect to the needle 'N between the button holder 32 and the finger 34, to hold the same between the holder and finger in executing the cycle of movement in the sewing of the button sewing machine.

The usual button sewing machine work and button holding clamp 31, where it is released upon the work supporting anvil 33, may retain the manual button holder 10 or 10a in position without hazard to the operator, as the branches 11 and 12, of 11a and 12a of the holder in no way interfere with the clamping engagement of. the machine buttonholder 32 and the opposed finger 34.

'By'the construction described, the ridges 20 are brought into intermediate clamping engagement with the fabric F over the anvil, to provide an effective sewing'operation as described in connection with the manual sewing method.

While I have shownand describedabutton seat 35 in the form of a concave surface which .isarranged to seat the ffrontface ofthebutton, .with thebranch 11 or 11a of the"holder removed, I may retain the holder 10 or 10a in position during button sewing operations and for this purpose the seat 35 may be formed with a clearance slot 36, extending diametrically across the seat 35, thereby further guilding the branch 11 or 11a in an oriented position transverse to the direction of movement of the needle N, and thereby accurately orienting the sewing hole aperture 16.

The construction not only permits a rigid holding of the button in accurate oriented position of the thread aperture to the needle but provides an intimate clamping of the rear face of the button on the fabric in relation to the work supporting anvil 33, to locate the button in an erect position, whether the stitch is effected over an edge of the fabric or by a blind stitching penetration.

A method of sewing buttons is thereby provided in which close contacting engagement of the button and fabric is made possible by the use of a shankless button by positioning one or both ridges of the button against the fabric and an anvil portion while orienting the sewing holes quickly to carry out the stitching operations.

The device and the method of operation therefore lend themselves to sewing shankless or self-shank buttons without hazard-and without requiring unusual skill and highly dexterous operators to carry out the operations.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent, is
