8 Claims.

This invention relates to improvements in work holders for sewing machines.

The objects of the invention are:

First, to provide an improved work holder for the attaching of patches or labels and for general use as well.

Second, to provide such a structure which is conveniently used as an attachment,

Third, to provide such a work holder with a presser foot which acts by gravity.

Objects relating to details of construction and operation will appear from the detailed description to follow.

A structure showing a preferred embodiment of my invention is illustrated in the accompanying drawings, in which:

Fig. l is a perspective view of my improved work holder and label presser foot in position on a sewing machine, the sewing machine being indicated by dotted lines.

Fig. 2 is an enlarged detail iront elevation of the structure seen in Fig. l, portions being in section on a line corresponding to line 2 2 of Figs. 1, 3, 4 and 5.

Fig. 3 is an enlarged sectional fragmentary `detail plan View taken on a line corresponding to line '3 3 of Fig. 5, showing the label at the completion of the stitching operation.

Fig. 4 is an enlarged plan view of the main presser foot detached and the label presser foot omitted, showing operation by dotted lines.

Fig. 5 is an enlarged detail vertical section taken on line corresponding to line 5-5 of Figs. 2, 3 and 4.

Fig. 6 is an enlarged detail perspective view of the label presser foot.

Fig. 7 is a detail perspective view of a label attached to fabric.

The parts are identiiied by their numerals of reference which are the same in all the views.

1 is the sewing machine base, 2 is the arm and 3 is the head. The machine is provided with a traveling work holder plate 4 which is oo ntrolled and actuated by the actuating mechanism' like that appearing in my former Patent No. 1,223,617, issued April 24, 1917.

6 is the work presser foot capable of heilig raised by the connection 7 for the introduction of the fabric of a garment therebeneath for the application of a label thereto. This presser foot is made up of a main shank 61 which carries side members 62, 63 which are adjustable on the back bar 64 by set screws 65, 66. Between the sides 62, 63 is formed a space 67 to receive a label.

Patch or label guides 8, 8 are carried by the side members 62, 63 and are retained by screws 81. The guides 8, 8 are adjustable in ways 82 so that they can be adjusted to and from-the back bar 64 to `Vregulate the size of the label space.

The work presser foot 6 is carried on the plate 4. after it has clamped the work in place. There is a central aperture in the plate 4 across which the fabric is extended.

9 is the label presser `foot of dimensions to substantially ll the label space provided in the work presser foot 6. 10 is the label presser foot shank which projects laterally at 102 and to which the label presser foot is pivoted Yat 91. This presser foot shank is slotted at 101. Pin 92 on presser foot 9 engages in slot 101 to limit the movement of presser foot 9 and permit it to seat evenly.

l1 is the guide plate for the shank 10. The shank is freely retained thereon by the cross bars 111 and 112. The shank is narrower at the bottom than at the top and free to swing from side to side, but is guided in a vertical Vplane transverse to the arm 2 of the-sewing machine and parallel with the front of the sewing machine head 3. The shank 10 projects laterally at `the bottom at 162 so that when the label presser foot is elevated it tends to swing Ato one side.

A sloping rest 12 with stop screw 121 is provided on the work presser foot to support the label presser foot in elevatedA position while la label or patch is being fed in.

The label presser foot is provided with transverse ways 93 to embrace and travel over the label guides 8, 8. The shank l`0 is provided with a lift pin 103 which is engaged by lift finger 13 connected tothe starting and stopping lever of the sewing machine.

.14 is the needle bar carrying a vertically reciprocatng needle of the usual form. The shuttle, stitching means, and thread are not illustrated as they are of usual construction and not part of my invention'.

I have thus described the parts and relations o1" my improved label presser foot device. In operation the label presser foot is Yswung up vand supported. at the sidef as 'indicated in Fig. 1. A label is then introduced and slides down the label guides 8, 8 into the space provided for it. The sides 62, 63 are adjusted in proper dimension and relation to the side of the label and the guides 8, 8 are adjusted to such point that the label slides down and beyond the end of the same into the space, as indicated in Figs. 4 and 5.

The operation is as follows, considering the operator as sitting at the left of Figure 3. The work and label carrier move forward (toward operator), thus stitching the left hand end of the label from the center thereof to the far corner. The work and label carrier, as Well as the label presser foot, then move toward the left a distance equal to the length of the label, thus stitching the far side of the label. The work and label carrier then move outwardly, or away from the operator, a distance equal to the Width of the label, thus stitching the right hand end of the label. The work and label carrier then move to the right a distanceequal to the length of the label, thus stitching the front side of the label adjacent the edge of the label presser foot, and finally the carrier moves toward the operator, whereby the forward half of the left hand end of the label is stitched.

It will be seen that the shank 10 adds to the Weight of thepresser foot and assists in holding it in place, and is a convenient and expeditious means for handling the same. The presser foot, however, might be a mere weight and be introduced by hand, and the operator might manipulate it so that it would hold the label and do its work in the manner here indicated. It is, of course, much better to have the presser foot handled by the shank.

While this structure is illustrated particularly in attaching labels, it is often desirable to stitch in designs, as in squares or rectangles as for ornamental purposes,and my improved structure with the presser foot within the apertured work holding presser foot capable oi movement similar to that here illustrated and described, is of great advantage in accomplishing this work, as it prevents the skipping of stitches and insures even perfect work. The structure can be adapted to various designs by proper formation of the relative parts.

I desire to state that the structure can be very greatly modified without departing from my ine vention. I desire to claim the invention in the speciiic form illustrated and also broadly as pointed out in the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. The combination with a sewing machine, of a traveling work holder plate with an aperture at the center, a work presser foot with label opening with adjustable sides to regulate the size of said opening for receiving a label, label guide fingers leading to the label opening, a label presser foot of a size corresponding to the label opening with slots to accommodate the label guide lingers, a pivoted shank for the label presser foot, a stop for limiting the movement of the said presser foot thereon, and vertical guides for guiding the shank in a plane transverse to the face of the sewing machine head whereby the label may be stitched with its edges in close proximity to said label presser foot and the label moved under the label presser foot in lateral direction when stitching the ends, coacting as specified.

2. The combination with a sewing machine, of a traveling work holder plate with an aperture at the center, a work presser foot with label opening, label guide iingers leading to the label opening, a label presser foot of a size corresponding to the label opening with slots to accommodate the label guide ngers, a pivoted shank for the label presser foot, a stop for limiting the movement of the said presser foot thereon, and vertical guides for guiding the shank in a plane transverse to the face of the sewing machine head whereby the label may be stitched with its edges in close proximity to said label presser foot and the label moved under the label presser foot in lateral direction when stitching the ends, coacting as speciiied.
