6 Claims.

The invention relates to new and useful improvements in a binder supporting means for sewing machines, and more particularly to a binder supporting means for a machine of the type shown and described in the patent granted Norman V. Christensen and Frederick F. Zeier, March 25, 1930, No. 1,751,508.

An object of the invention is to provide a binder supporting means whereby the binder may be attached to the standard of the machine and supported entirely free of the work support.

A further object of the invention is to provide a binder support of the above type wherein the binder may be moved from operative to inoperative position and secured in either position.

A still further object of the invention is to provide a binder support of the above type wherein the binder may be adjusted vertically and laterally and longitudinally of the line of feed.

In the drawings which show by way of illustration one embodiment of the invention Figure l is a front view of a machine having the invention applied thereto;

Fig. 2 is a plan view of the same with a portion of the needle head broken away to show the position or" the binder relative to the work support;

Fig. 5 is a view partly in front elevation and partly in section of the supporting bar and the carrying plate therefor on which the binder is mounted, the bar being shown in broken lines with the binder shifted to inoperative position, and

Fig. 6 is a section on the line 6-6 of Fig. 5.

In the Christensen and Zeier patent there is shown a machine of the type wherein there is a supporting standard carried by a supporting bed, and this standard carries a projecting portion having bearings for the actuating shaft. The actuating shaft extends in the general direction of the line of feed. There is a work support mounted on the bed which extends only a short distance beyond the line of feed and toward the standard. The present invention has to do with the placing of a binder for directing a binding strip about the edge portion of a fabric being stitched, and a supporting means therefor which is mounted on the standard. The supporting means includes a carrying plate which is attached to the standard and which is provided with a dovetailed recess in which a supporting bar slides.

A latch is provided for holding this bar in two difierent fixed positions on the carrying plate. Attached to the bar is a bracket on which the binder is mounted. The binder is mounted on the bracket so that it is adjustable bodily longitudinally of the feed. The bracket is mounted on the bar so that it is bodily adjustable in a direction laterally of the line of feed, and the carrying plate is mounted on the standard so that it is adjustable vertically. This provides for all the necessary adjustments to insure the proper setting of the binder relative to the work support, and it also provides a means which is entirely independent of the work support for supporting the binder.

Referring more in detail to the drawings, the machine to which the binder is applied includes a supporting bed 1 carrying a standard 2. The standard has a laterally projecting portion 3 carrying bearings 4 and 5 in which the actuating shaft 6 is mounted for rotation. At the forward end of the standard is a needle bar 7 carrying a needle 8. Cooperating with the needle beneath the work support is a suitable stitch forming mechanism for forming a line of stitches. The shaft is connected to the needle bar for reciprocating the same. Also mounted on the supporting bed 1 are supporting members, one of which is indicated-at 9, and the work support 10 is carried by these supporting members. The work support it is provided with a throat plate 11. The needle passes through an opening 12 in the throat plate. The throat plate is provided with slots through which the feed dog 13 operates. The line of feed is in the direction of the arrow a in Fig. 2. It will be noted that the work support 10 extends for a short distance beyond the line of feed, that is, to the right thereof toward the standard 2. The invention has to do particularly with a binder and the supporting means therefor on a machine of the type described. The binder is indicated at 14. It is of the English binder type, and it is not thought that a detail description thereof is necessary. It may be said that as the strip passes through the binder, its edges are folded on to one face of the strip, and the'strip is then caused to pass in a direction at right angles to its direction of movement into the binder, and is inverted and thus placed about the edge portion of a fabric with the edges of the binder strip infolded. If a binding strip with a selvedge is used, then, of course, the binder will not necessarily be provided with means for folding the edges of the strip. The strip, however,

a recessed portion 15 in front of the needle opening 12. The binder 14 extends into this recess. The throat plate is elevated slightly from the plane of the work support 10 so that the body fabric is raised sufiiciently to permit the body fabric to pass through the end of the binder and between the upper and lower portions of the binding strip as they pass from the binder. The binder is mounted on a carrier 16 which is attached t0 the standard 2 by screws, one of which is indicated at 1'7. These screws pass through elongated slots 18 in the carrier plate, and these slots are so shaped as to permit the carrier plate to be raised and lowered or moved in a vertical direction and then secured in the desired set position. The carrier plate 16 is provided with a dove-tailed recess 19. A dove-tailed bar 20 is mounted in this dove-tailed recess, and thus the bar is held on the carrier plate so that it can move only in an endwise direction thereon. It will be understood, of course, that while a dove-tailed recess is used, other ways may be provided for mounting the supporting bar on the carrier plate for endwise movement thereon. Attached to this bar 20 is a supporting bracket 21. Said bracket 21 has elongated slots 22, 22 therethrough, and screws 23, 23 passing through these slots firmly clamp the bracket to the bar. By loosening the screws, the bracket can be shifted in an endwise direction on the bar. This is for the purpose of adjusting the position of the binder in a direction at right angles to the line of feed or laterally thereof.

The bracket 21 has a right angle plate 24. Attached to this right angle plate 24 is a supporting plate 25 on which the binder 14 is mounted. The supporting plate 25 is provided with elongated slots 26. Screws 27 pass through these slots and secure the supporting plate 25 to the bracket 21. These elongated slots 26 extend in a direction substantially parallel with the line of feed and provide for adjustment of the binder toward and from the needle. The supporting plate 25 has an upturned portion 28 and the binder is attached to this upturned portion by screws 29, 29. These screws 29 pass through elongated slots in the supporting member 30 which is integral with the binder and supports the same. This provides another means for shifting the binder vertically.

As a means for holding the bar 20 in set positions, a latch arrangement has been provided which consists of a rod 31 mounted in a vertically extending recess 32. The rod is provided with a handpiece 33 at the upper end thereof. The recess 32 terminates short of the lower end of the carrier so that the bottom end of the recess serves as an abutment for the spring 34 located in the recess. This spring at its upper end bears against the lower end of the rod. The rod is cut away at 35 for a distance so that when the rod is depressed the bar 20 is free to slide back and forth in the recess 19. The lower edge portion of the bar 20 is provided with two notches 36 and 37. The portion 38 of the rod when in register with the notch 36 will be raised by the spring into the notch. By pressing on the handpiece 33, the rod is depressed so as to release this portion 38 from the notch, and the bar can then be shifted until the portion 38 springs into the notch 37. When, the latch rod is in the notch 3'7, the binder is in inoperative position and will be held from movement. When the latch is in the notch 36, then the binder is in operative position. When the latch. is depressed, the bar may be completely removed from the'recess l9 and thus the binder taken from the machine. This provides a means for supporting the binder from the standard of the machine. The cloth plate terminating as it does adjacent the line of feed, does not afford a supporting means for the binder which must be so disposed as to lead the binding strip toward and about the edge of the fabric being stitched. Furthermore, the supporting means includes a ture whereby the binder may be quickly shifted from one set position to another, that is, from operative to inoperative or from inoperative to operative position. During the shifting of the binder, there is no adjustment of the supporting parts lost. All of the supporting parts which provide for the adjustment of the binder in the direction of f ed and laterally of the feed, are bodily shiftable to the inoperative position. Therefore, when the binder is returned to its set operative position, the same adjustment is obtained as before moving it away to inoperative position. Furthermore, the structure for supporting the binder affords a ready means whereby the binder may be adjusted on the bar which is shiftable on the carrier plate.

It is obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is-
