Application December 6, 1950, Serial No. 199,404

This invention relates to improvements in but.- ton attachments for sewing machines and re-. lates more particularly to such attachments as are used on power machinesemployed in the manufacture of garments.

The principal object of the invention is the provision of a device which has a wall extending upwardly from the foot portion and having therein' a passage to receive the shank or stem of the button, so that as a button is firmly held against this wall with its stem positioned in said passage, the stem is in the correct position to have the needle of the machine to pass vertically down through it. and the fabric to which the button is to be sewn, during one stroke and to have the needle clearthe end of said stem during the next stroke-,so that the length of the bundle of threads on the opposite face of the fabric is no longer thanthe spacingof the two paths of the needle.

Another-object of the invention is the provision of said upwardly extending wall both as a firm.

support against which the buttons arepressed, and also as a safety device which positively prevents the fingers of an operator from getting into the range of the needle.

Yet another Object of the invention is the provision of an improved support for the garment, or other work, beneath the foot of my device, which insures faster application of the buttons to the garment and the disposal of the buttons in a neater array.

Another object of the invention is the formation-'of a single blank form which is adapted to be cut out to accommodate any given size and style of button, so that as new styles, types, and size are encountered, devices embodying the features of the invention may be easily made up.

Other objects and advantages of the invention will be apparent to those skilled in the art upon a study of this specification and the accompanying drawings.

Referring to the drawings, which are given by way of example to teach others to practice the invention;

Figure 16 is a view of the opposite face of a piece of fabric after a button has been applied thereto with my device; and

Figure 17 is a view of the opposite face of a piece of fabric after a button has been sewn thereon utilizing the prior art device shown in Figure 2.

In the prior art there are two general forms of button devices. One of them is shown in Figure 1 and designated by the numeral 20.. It has avertical plate portion Zlwhich is slotted for attachment to the machine, and a horizontal plate portion with a notch 23 therein to accommodatethe stem or shank of the button, and aslot 24 communicating therewith for the needle. With this device, there is nothing to guide the operator as to whether the button is straight or not, and also there is nothing to keep the'fingers of the operator out of the path'of the needle.

The other form is shown in Figure 2, and designated by the numeral 25. It has a vertical plate portion 26 which is slotted for attachment to the 1 machine, and has a horizontal plate portion 21 formed integral therewith. Extending downwardly from the left edge of the portion ZI'are parallel portions 28 and 29 with a space 30 between them. A slot 3| in the portion 21 flares outwardly and joins thespace 30 which is widened at 32 to accommodate the stem or shankof the button. With this device a work support; 33 in the form of a rod having a slotted end is employed. The fabric to which the button is to of my new de-- be sewn is shown at 34 in Figure 2, and the reverse side of this fabric, after the button 35 has been applied, is shown in Figure 17. The bundle of threads 36 securing the button is not only objectionably long but it wastes thread.

In this form, the portions 28 and 29 do tend to guide the button straight, but the position is awkward and there is nothing to prevent the operators fingers from getting into the path of the needle.

According to my invention, referring first to Figures 3 to 9 inclusive, my device 40 comprises an L-shaped member and a vertical plate portion 31 having a vertical slot 38 formed therein for attachment to the machine. Formed integral with the portion 31 is a horizontal portion 4| which has a laterally extending slot 42 therethrough, through which the needle passes to engage the shuttle. The portion 4| also has a depression 43 formed therein, centralized with respect to the axis of the slot.

Preferably formed integral with the horizontal portion 4|, although it may be made of a sepa-- ratepiece of material secured thereto, is an. upstanding vertical wall 44 which has apassage 45 therethrough of a shape andsize to accommodate the shank or stem of the button. Since the central horizontal plane of this passage is substantially level with the upper surface of the portion' 4|, an extension 4541 of this passage 45 is formed in the portion 4| and communicates with the depression 43, as may be seen in Figure 9. In Figure the passage 45 isshown as somewhat ovalin form, but'itwill be understood that this passage may be of any other shape, to accommodate the shank of. any type or style of. button to be used.

A vertical slot 46 is formed in the portion 4.4, and it communicates with the passage 45 and with a depression 41 also formed in the portion 44.

This depression extends through the upper edgeof the portion 44, leaving a narrow web of material 41a and thereby providing ample clearance forthe needle.

Referring toFiguresll and 12, I show one of my new devices described above, and its relative position with respect to a work supportv 50. A button 49 is placed on' the device with its shank 5| positioned in the passage 45 with the hole 52 therein extending vertically in line with one path 53a of the needle. The needle when moving vertically alongits second path 53b clears the end of the shank 5|. It will be noted that the work 48 is horizontally disposed and consequently the length of the bundle of threads 54 (Figure 16) on the opposite face of the work is approximately equal to the distance apart of the needle paths 53a and 53b, and thereby a neater job is performed and a substantial sewing of thread is effected.

Thework support 50, which may be also seen in Figures 13 and 14 is preferably comprised of a stamping having an open slot 54 extending in from one end, and oppositely disposed depending locating tabs 55 and 56. Adjacent to the other end is an elongated slot 5'! which extends axially of the support and provides clearance for the needle. On said last end is a depending tab 58, the inner'surface of which is beveled. This work support is secured on a shaft element 59 by means of a screw 6|, and due to the slot 54, which rides the screw, the end 58 may be set in any desired position relative to my device.

In Figure 15, I show my improved blank, designated by the numeral 60. The vertical plate 4 portion 3'! has the attachment slot 38 formed therein, and the portions 4| and 44 are blank so that they may be formed to accommodate practically any type of button.

Although I have herein shown and described by way of example one embodiment of my invention, it will be understood that many variations in the device, shown and described, are within the scope of the appended claims.
